Importance of dynamic managerial capabilities on the performance of small family businesses

This research aims to determine how an entrepreneurial chief executive officer’s (ECEO) level of dynamic managerial capabilities (DMCs) influences the performance of small family firms, as well as family firm governance structure moderates this relationship. Additionally, this paper offers insights into one antecedent of ECEOs’ DMCs, namely managerial human capital. A total of 213 observations were obtained from ECEOs who have founded and operate a minimum of one small family firm in Mexico. After testing the hypotheses using a structural equation model, a positive relationship was found between the level of an ECEO’s DMC and family firm performance. It was further observed that family governance structure in the firm could positively moderate ECEO DMCs’s effect on firm performance, where family governance structure was calculated as the number of family members that work in the family firm independently, formally, or informally, as well as whether they work full-time or part-time. Overall, the results indicate that in small family firms, the ability to change and adapt to create a sustainable competitive advantage depends, to some degree, on certain types of individual capabilities (DMCs), rather than simply on organizational capabilities, known as dynamic capabilities (DCs).  Corresponding author.

Introduction
Today's fast paced-world forces firms to adapt fast to environmental changes. Such adaptation behaviors can include, among others, doing nothing and ignoring the situation, ad-hoc problem solving, trial and error efforts, and developing dynamic capabilities (Teece, 2007;Teece, 2018;Winter, 2003;).
There are well-documented cases where the use of dynamic capabilities (DCs 1 ) has resulted in positive firm-level outcomes. One of such examples is IBM's impressive transformation in the 1990s, which saw the firm successfully shift its core business from hardware manufacturing to providing services and software. In 1993, these latter divisions roughly represented 27 percent of the firm's revenues, but by 2001, they represented 58 percent (Harreld et al., 2007). Samsung Electronics' transformation in the semiconductor industry is another case where use of developed dynamic capabilities (DCs) contributed to firm survival and success (Lee and Slater, 2007).
In contrast to the IBM and Samsung Electronics cases, Smith Corona, once the world's leading typewriter manufacturer, collapsed by the mid-1980s due to rapid and pronounced market dissipation of their main products and despite its efforts to exercise all available DCs (Danneels, 2011). In this case, DCs only served to delay for some years the firm's unavoidable and imminent financial bankruptcy.
These three cases demonstrate how DCs are necessary but not sufficient alone to achieve superior performance; furthermore, simply applying DCs will not always enable successful organizational adaptation (Eisenhardt and Martin, 2000;Ferreira et al., 2019;Leih, and Teece, 2016;Miles et al., 1978;).
In 2003, Adner et al. asserted that individual characteristics are a central element in an organization's general dynamic capability to change by introducing the concept of dynamic managerial capabilities (DMCs 3 ). Martin (2011) and Zhang (2007) argue that top managers' DMCs can be considered one of the most critical determinants of a firm's long-term competitive advantage and survival probability. DMCs highlight the importance of managers in building, integrating, and reconfiguring a firm's resource base.
In this sense, our study is mainly built upon the foundation of the DMC approach, applying it to the context of small family firms to answer the following questions: (1) how does an ECEO's level of DMCs influence firm performance; and (2) how does family involvement moderate that relationship?
In general, our results provide several insights into how DMCs allow small family firms to survive longer and achieve superior financial performance. Also, since all the ECEOs that responded to the study questionnaire were purposely chosen for also being their firm's founders, our study is able to link to entrepreneurship, which has been argued by several authors to be of special interest to the managerial literature (Friedman et al., 2016;Teece, 2016).
Furthermore, our results support other studies that have found that dynamic capabilities have an indirect effect on performance and competitiveness, via managerial capabilities, among other variables (Ferreira et al., 2019).
Our study also shows how family firm governance structure positively moderates the positive effect of an ECEO's DMCs over the firm performance. Finally, we explore how the managerial human capital of an ECEO, one of the antecedents of DMCs, influences that ECEO's DMC levels.

Dynamic Capabilities
The recently proposed concept of DCs has its roots in other strategic theories, such as the resource-based view (RBV), transaction cost theory (TCT), behavior theory, and evolutionary theory. The DC framework extends the RBV by explaining how some firms, especially multinational ones operating in dynamic environments, can "integrate, reconfigure, renew, and recreate its resources and capabilities and, most importantly, upgrade and reconstruct its core capabilities in response to the changing environment to attain and sustain competitive advantage" (Wang and Ahmed, 2007:35). Since its emergence in the last decade of the XX century, the field of DC has advanced, but many areas remain to be developed (Ambrosini and Bowman, 2009). From its inception, DCs have been defined in varied ways, but to some degree, all share some basic congruence. First, Teece et al. (1997) describe DCs as "the firm's ability to integrate, build, and reconfigure internal and external competences to address rapidly changing environments." Eisenhardt and Martin (2000) disaggregate DCs neither as capabilities nor abilities, but as processes to integrate, reconfigure, gain, and release resources. Teece (2000) disaggregated DCs in two main capabilities-sense and seizing opportunities. In 2007, Teece expanded his theory to incorporate a firm's transformation capability. In this sense, according to Teece (2007), DCs "can be disaggregated into the capacity (a) to sense and shape opportunities and threats, (b) to seize opportunities, and (c) to maintain competitiveness through enhancing, combining, protecting, and, when necessary, reconfiguring the business enterprise's intangible and tangible assets" (Teece, 2007). Furthermore, recent advances in the field of DCs has emphasize a need for a more dynamic perspective that addresses innovation in the business model (e.g., Hacklin et al., 2018;Massa et al., 2017).

From Dynamic Capabilities to Dynamic Managerial Capabilities
Although DCs have been described as an organization's meta-routine (Feldman and Pentland, 2003), this complex, intricate set of processes can be untangled to reveal the individual routines performed by specific individuals, such as executive leaders, CEOs, ECEOs, and the top management team (TMT). Building on the work done by Teece et al. (1997), Adner andHelfat (2003) introduced the concept of DMCs to stress the importance of managers' strategic role in decision making to "build, integrate, and reconfigure organizational resources and competences." This was extended by Helfat and Martin (2015) as "the capabilities with which managers create, extend, and modify the ways in which firms make a living." This definition also implies a possible modification in the current business model. Martin (2011) mentions that DMC is "a dynamic capability;" that is, DCs encompass all levels of analysis for examining the organizational meta-routines and processes, whereas DMCs reflect the individual level of analysis of routines and processes, as highlighted by Eisenhardt and Martin (2000) and Rothaermel and Hess (2007). In a sense, managers are the facilitators of DCs. Augier andTeece (2009), andTeece (2018) argue that managers play important roles in firms, in spite of being omitted from several business and economic theories.
Managers must act entrepreneurially, think strategically, and execute flawlessly to provide their organization with the capacity to sense and seize opportunities, and then transform and reconfigure according to the dictates of such opportunities and competitive forces (Augier and Teece, 2009). In this regard, the fundamental and distinctive role played by managers in the DCs framework centers on "selecting and/or developing routines, making investment choices, and in orchestrating non-tradable assets to achieve efficiencies and appropriate returns from innovation." Martin (2011) and Zhang (2007) argue that top managers' DMCs are one of the most crucial determinants of DCs and a firm's long-term competitive advantage and survival, evidence 6 to sustain such ideas can be found on the work done by Fainshmidt, et al. (2017). According to Zhang (2007), top managers' DMCs not only allow executive leaders to enhance a firm adaptability to adapt to its environment, but also let them to acquire and incorporate into the firm other valuable resources and capabilities that serve as the antecedents of valuable products and services.

DMCs in Small Family Firms: Role of Entrepreneur CEOs
Our literature review shows that numerous studies have explored the macro-foundations of DCs and how they affect organizations. However, the literature on the micro-foundations of this type of (dynamic) capabilities is more limited, with many aspects still unexplored. One of these aspects is the DMCs of major owners and general managers of small family firms.
Former studies focusing on CEOs and/or top managers and their DMC conducted their analyses in the context of large-size organizations. Furthermore, they analyze CEOs who are not necessarily the founder of the firm. Due to the importance of DCs in general and in DMCs in particular, the aforementioned arguments have motivated this study to make ECEOs' DMCs the principal subject of analysis. Furthermore, this study focuses on a very particular type of CEO, namely CEOs who are also founders of the firm they manage, referred to hereafter as an entrepreneurial CEO or ECEO. Friedman et al. (2016) conducted a more detailed analysis of CEOs' DMCs in small firms. They found that CEOs may be more influential in small entrepreneurial firms than in larger ones, specifically in terms of influencing the firm's capacity to adapt to a changing environment. This positive influence is possible due to the fact that the CEO's transformational leadership "facilitates behavioral integration and comprehensiveness in the decision process among members of the TMT, which in turn enhances organizational capacity to adapt to environmental changes" (Friedman et al., 2016). Analyzing the structure and trends in the literature regarding family business during the period 1961-2008, Benavides-Velasco et al.
(2013) identified the importance of using the RBV and DCs (Teece et al., 1997;Teece 2007) as potential avenues for future research that could be significant in advancing consolidation in the discipline.
In general, we discovered that the empirical studies in our literature review confer a positive influence from underlying managerial resources (like managerial cognition, managerial social capital, and managerial human capital) on DMCs (Bertrand and Schoar, 2003;Salvato, 2003;Tripsas and Gavetti, 2000). Also, several reviewed studies show that DMCs positively influence firm performance (Fainshmidt et al., 2016).

Research Hypothesis
The literature review implies that the greater underlying managerial resources that a CEO possesses, the more DMCs he/she will possess, and in consequence, he/she will better enhance the firm's performance (Figure 1). Building on this view, we argue for the existence of a moderation effect of family firm governance structure on ECEO's DMC, where performance is contingent on specific firm characteristics (e.g., lifecycle stage).

ECEO DMCs and Firm Performance
We discuss that if the TMT and the CEO, in particular, can have such a dramatic impact on the DCs of a firm and its performance (Augier and Teece, 2009;Fainshmidt, et al., 2017;Helfat and Peteraf, 2015;Kor and Mesko, 2013;Rodenbach and Brettel, 2012), then it is logical to think that an ECEO could have even a greater imprint on a small organization's DCs as well as on the firm's performance. Further, ECEOs could provide greater hints regarding the so-called micro-level origin of DC (Rodenbach and Brettel, 2012). These arguments are supported by a great number of theoretical and empirical studies on DCs and DMCs, many of which have been mentioned above, such as, Augier and Teece (2009) Prior empirical studies on DCs found a positive and significant influence on performance outcomes such as firm performance (Fainshmidt, et al., 2017;Martin, 2011;Rosenbloom, 2000;Sirmon and Hitt, 2009;Zhang and Rajagopalan, 2010); adaptive intelligence of organizations (Tripsas and Gavetti, 2000); and competitive advantage (Schilke, 2014). In this study, we are interested in measuring firm performance as an outcome variable of DMCs.
Regarding prior empirical studies that focused on the relationship between DMCs and firm performance, Sirmon and Hitt (2009) observed that asset orchestration, a central component of DMC, generally enhances firm performance. According to them, firm performance, referring to economic performance, is measured using a market-based measure of economic performance, namely Tobin's q, which compares the firm's market value to the replacement costs of its assets. Furthermore, Fainshmidt, et al. (2017). found evidence that suggest that top managers' DMCs, referred as asset management capabilities, is positively associated with the in-crisis performance of the firm.
In his study, Martin (2011) explores the relationship between the DMC characteristics of the set of business-unit general managers (i.e., DMCs characteristics at group level) and firm performance. The profit measures used by Martin (2011) are return on investment or return on sales, which are similar to that used by Zhang and Rajagopalan (2010).
Firm performance can not only be measured on financial terms, but also by other means.

Family Firms Governance Structure moderates the ECEO DMC and Firm Performance relationship
When discussing about a family firm governance structure, it should be noted that in essence one is talking about the different ways that the family's involvement in the firm significantly influences its behavior and outcomes (e.g. performance). Family involvement in the firm could be throughout its ownership, management, and governance, aspects that researchers have long sought to understand (e.g., Daspit et al., 2018;Sharma et al., 1997). Prior studies suggest that two particular types of governance (family involvement in firm ownership and management) are among the main sources of family firm heterogeneity, and that both influences the financial performance of family firms Dekker et al., 2015;Stewart and Hitt, 2012).

Sacristan-Navarro et al. (2011) mention that what matters is the extent to which the family
is involved in management, and that ownership does not affect family firm performance and profitability. Some explanation to the later ideas is that the proportion of family members in the management team allows the implementation of family objectives within the business enabling the principal-agent alignment .
In this regard, this paper focuses on one specific type of family involvement, the management one. For practical purposes, we will refer to this type of family involvement simply as the governance structure of the firm.
Family firm governance structure could have both positive and negative outcomes. Previous research has not been conclusive, and results are mixed regarding how and in what circumstances family involvement functions as an enabler resource or a barrier for growth in small firms (Rutherford et al., 2008;Zahra, 2005).
Sirmon and Hitt (2003) list some specific instances where there is a possibility that family firms have a superior competitive advantage over non-family firms, and it could be inferred that these advantages can be traced to family governance structure. Additionally, scholars have found that when a small number of family members owns and controls the business, such as the founders, their focus is predominantly on the firm's long-term economical sustainability (Schulze et al., 2003). Moreover, family members' participation in the firm's activities is generally acknowledged as essential in fostering the accumulation of socioemotional wealth, forging a shared vision and goals for the firm and generating a positive set of feelings in relation to commitment and collaboration to the business (e.g., Chirico et al., 2011;Eddleston and Kellermanns, 2007;Goel et al., 2011;Le Breton-Miller and Miller, 2013;Lubatkin et al., 2005).
Contrarily, family governance structure can have negative consequences or a "dark side" for business outcomes due to additional demands by family members, rule of primogeniture, dysfunctional conflicts, and a lack of professional knowledge (Nicholson, 2008;Schulze et al., 2001). Campopiano et al. (2014) contend that family governance structure, which is measured as the ratio of family members in key managerial positions to total number of family members working in a particular firm, can result in opportunistic behaviors and can, subsequently, prove to be detrimental to the business' sustainability.
In addition to the aforementioned studies, it should be noted that the effects of family governance structure could also be contingent upon circumstances. For instance, Jaskiewicz et al. (2013) found that nepotism could be either beneficial or harmful depending on the specific circumstances of each individual firm. Similarly, Karra et al. (2006) argue that family governance structure could be an advantage or a disadvantage depending on the stage of the firm. Specifically, they find that when a family firm is in its early stages, the positive effects include alignment of the interests among family members due to altruism and a reduction in the agency costs. However, as a family business becomes more mature and bigger, these benefits start decreasing.
Another study related with governance contingency is that of Madison et al. (2018). These authors suggest that family firms are heterogeneous in their application of human resources practices, and that in some instances family and nonfamily employees are treated differently, while in other both employees are treated the same. Perceptions of injustice may attenuate the firm-level benefits (e.g. enhance firm performance) associated with human resources practices of hiring more nonfamily employees.
Based on the studies above, we argue that the effect of family governance structure on performance-related outcomes in small family firms is contingent on specific firm characteristics (e.g., lifecycle stage) and the family members involved. That is, that for small family firms the family involvement should positively influence the firm performance, rather than negatively.
H2. Family governance structure will positively moderate the relationship between the level of an ECEO's DMCs and firm performance. Helfat and Martin (2015) state that DMCs employ a set of underlying managerial resources: managerial cognition, managerial social capital, and managerial human capital (MHC). For these authors, the concept of MHC refers to the knowledge and learned skills that individuals develop through multiple different experiences, such as education, training, work, and extracurricular activities. MHC also includes other individual psychological attributes like general intelligence (cognitive ability), values, interests, type of leadership, and personality (Helfat and Martin, 2015).

Relationship between MHC and DMCs
The evidence suggests a positive relationship between the underlying managerial resources and DMC of managers and CEOs (Haunschild, 1993;Huy and Zott, 2019;McDonald and Westphal, 2003;Nadkarni and Narayanan, 2007;Prashantham and Dhanaraj, 2010). Studies further confirm the influence of MHCs on DMCs; however, the direction of such an effect is not entirely clear (Barker and Mueller, 2002;Bertrand and Schoar, 2003;Rosenbloom, 2000;Tripsas and Gavetti, 2000). Barker and Mueller (2002), Bertrand and Schoar (2003), Datta et al. (2003), and Rothaermel and Hess (2007)  H3. The MHC of an ECEO will be positively associated with the levels of his/her DMCs.

Methods
A quantitative survey study was conducted to examine the theory of DCs, specifically the relationship between DMCs and firm performance, which was controlled by factors such as firm age, size (sales and employees), and sector (manufacturing, services, or mixed). The unit of analysis for this study is the ECEO, and the research context comprises the small family firms in which those ECEOs work. Our general independent variable is the ECEO's level of DMCs: capabilities to sense and seize opportunities and threats, and create, extend, and/or change the ways in which firms make a living (i.e., how do managers improve their organizational DCs). The moderation variable of interest for this study is related to the family firm governance structure that was established by these ECEOs.
To test our hypotheses, we conducted a survey with a sample of 213 ECEOs from Mexican companies from diverse industries. The questionnaire went through an intensive pretesting process, with a pilot study conducted among four former ECEOs and three academic researchers (DeVellis, 2003). The questionnaire is composed of validated scales and has been published in high impact management journal in the field. Since the questionnaire was composed of different validated scales that were originally written in English, we rely on the use of the back-translation technique for the Spanish version of the questionnaire.
The final version was administered either online or face-to-face; in both cases, the questionnaire was self-administered by respondents. We used a three-wave mailing approach via e-mail, in accordance with Dillman (1978), to obtain more responses. From the total mailing list of 750 emails, we received 110 responses from Mexican ECEOs, giving a response rate of 14.6%, which is higher than the 9% proposed by Klassen and Jacobs (2001). We also collected 103 responses via face-to-face self-administration of the questionnaire. Data collection took place from July 2016 to February 2017.
We compared respondents with non-respondents by running the Mann-Whitney U tests concerning different important variables like firm sales, number of employees, and firm age.
No significant differences were discovered between the respondents and non-respondents, either in the e-mailed or in-situ surveys. Therefore, we find no evidence that suggests a significant non-response bias in our data.
Also, in order to verify the suitability of the selected key informants, we included some questionnaire items that asked whether the respondent founded the firm and/or ran the business as ECEO. We also asked if the respondent had founded more than one business. In case of the respondents who had founded more than one, we explicitly asked them to focus on only one of their businesses.
Finally, all the aforementioned procedures were used with the aim of increasing the quality of responses (Cycyota and Harrison, 2006). For instance, all respondents were assured full anonymity of the information given.

Sample Sample Design
The empirical analysis is mainly based on survey data collected from ECEOs of small enterprises located in totality within Mexico. SMEs are firms that have no more than 250 employees or annual sales of no more than €50 million. According to the standards given by According to Wilden et al. (2013), small and medium firms tend to have more emergent strategies and a less formalized division of responsibilities. Furthermore, Friedman et al.
(2016) argues that small and medium-sized firms are great candidates to study DCs and DMCs.

Sample Selection
The sampling technique used to select subjects was convenience sampling because access to our key informants was hard to obtain, given their limited time availability unless the researcher was recommended by someone close to the interviewee. Convenience sampling is a procedure in which "the researcher selects participants because they are willing and available to be studied" (Creswell, 2005:149).
In addition to convenience sampling, we ensured that all our observations came from an ECEO, which, as we mentioned earlier, is defined as an entrepreneur who is the founder as well as CEO of the company under study.

Scale Development and Measures Independient Variable: DMCs
This study measures one complex construct, namely DMCs (independent variable). The scale was adapted from Wilden et al. (2013), who developed and validated a scale to measure dynamic capabilities from an organizational perspective instead of an individual one. We decided to adapt this scale after meticulously contrasting the theoretical differences between DCs and DMCs. One of the great advantages of Wilden et al. (2013)'s scale is that it can be broadly applied to many different types of organizations. Another advantage is that instead of measuring a specific type of dynamic capability, as is the case with most of the other scales in the literature, it measures the three sub-dimensions of DCs proposed by Teece (2007): sensing, seizing, and reconfiguring. The instrument was developed as a reflective measurement model.
Respondents were asked to assess how much they contributed into the processes that emerge from the three original dimensions of DCs on a seven-point interval Likert scale, where 1 = rarely or extremely infrequent and 7 = extremely frequent. Table 2 presents the constructs for measuring DCs exhibited convergent and discriminant validity. All Cronbach's alpha values were above the suggested value of 0.70 (Subramaniam and Youndt, 2005), and all loadings and weights were significant at the 0.001 level (2-tailed). Therefore, the instrument for measuring DMCs is valid and internally consistent. Discriminant validity was inspected using the Fornell and Larcker (1982) criterion, which basically states that in order for discriminant validity to exist, the AVE should be larger than the square root of its largest correlation with any construct, which all the constructs of DCs fulfilled.  Agle et al. (2006) pointed out that the operationalization of a variable like organizational performance has always been a challenge to scholars, and the literature on strategy, finance, and accounting has long suggested that both market and accounting-based measures suffer from a number of issues, like measurement and controllability, and that these different measures might even represent different constructs of organizational performance.

Dependent Variable: Firm Performance
In these latter cases, the alternative option to measure any type of organizational performance is that which is perceived by the key informants. To this matter, Delaney and Huselid (1996: 954) explain that researchers have found that measures of perceived organizational performance positively correlate with "objectives measures of firm performance".
In consequence, we decided to use two practical measures of financial performance. The first measurement is firm longevity. Respondents were asked for how long the firm has been in operation. The second is financial performance; basically, we asked for the average net income or profit for the total time the firm has been in operation.

Moderation Variable: Family firm governance structure
Family firm governance structure has been measured by scholars in different ways. For instance, Campopiano et al. (2014)

Control Variables
To test our hypotheses, several control variables that could influence the DMCs of ECEOs were specifically controlled for. Following Danneels (2008), we controlled for firm size and industry sector (goods or services). Firm size was measured by the number of employees (full-time-equivalent employees). Industry sector was differentiated with a dummy variable, whereby firms in the manufacturing sector were coded as 0, firms in the service sector were coded as 1, and mixed firms were coded as 2 (Rodebach and Brettel, 2012; Wilden et al., 2013). Therefore, two effect-coded variables were included as controls for industry.

Results and Discussion
Prior our statistical model testing and in order to develop our structural equation modeling, we first ensured that the data being evaluated complied with structural equation modeling (SEM) assumptions. We followed the main steps to develop a SEM model as recommended in literature (Weston and Gore Jr, 2006). Specifically, the assumptions analyzed for this study are as follows: sample size, multicollinearity, singularity, normality, and continuous variables.
Sample Size. Sample size has a direct effect on the predictive power of any statistical model, including SEM. The final sample size for this research is 213 observations, which could be considered sufficient according to the rule of thumb suggested in the literature (Tabachnick and Fidell, 2007;Hair et al. 2006;Luque, 2000).
Multicollinearity. Estimation with SEM can only be done properly if none of the independent variables in the model are perfectly correlated (Guillén, 1992). Our model contains no high correlation cases, a value higher than 0.80 is typically taken as indicating a multicollinearity problem (see Table 3). Additionally, we checked the Variance Inflated Factor (VIF) in all of our regressions models, and the highest value was below the threshold value of 10 given as a rule of thumb (Hair et al., 2006).
Normality. All analyzed variables in a regression model are required to be normally distributed to guarantee that the critical values do in fact determine the significance of each coefficient (Cea, 2002: 521). We first checked for individual normality in each variable in the model, which we then corroborated by checking for multivariate normality. Skewness values should be within the range ± 1 for normal distribution, and for kurtosis, values should be within range ± 3 for normal distribution (Cea, 2002: 521;Lowry and Gasking, 2014;Weston, and Gore Jr, 2006;735). In the present study all variables fit well /are well fit with these criteria.  Firm performance is an observable variable measured by profit average (profit Ave) and firm age (Firm Age).
Firm size (Firm Size) and industry (Industry) are introducing as control variables. The measures of model fit in Figure 2 also provide additional support for the fit of our theoretical model to the data. In many cases, the measures suggest an acceptable fit between the model and obtained data. Therefore, this supports the likelihood that our theoretical model is represents the actual experiences of the business owners in our sample. The most typical reported model fit indexes and the most common cutoff values are chi-square (CMIN/DF) less than 3 (for the present study is 2.47), CFI greater than .90 (.894), NFI greater than .80 (.836), and RMSEA less than .08 (.083) (Hair et al. 1999;Weston and Gore Jr, 2006).
Hypothesis 1 examined the relationship between the level of an ECEO's DMCs and firm performance. The model in Figure 1 shows that ECEO's DMCs are positively and significantly influential only when longevity is used to measure performance not for financial terms (annual profit average). The probability for this test is less than 0.001 (p < 0.001), thus partially supporting hypothesis 1. A standardized regression weight of 0.62 indicates that ECEO's DMCs influence the level of firm performance. Statistically, this means that a firm's performance improves by approximately 0.62 standard deviation units when the CEO's DMCs increases by one standard deviation.
Our findings support theory that exposes an ECEO's level of DMCs positively influences his/her firm's performance. This finding is consistent with the literature (Martin, 2011;Rosenbloom, 2000;Sirmon and Hitt, 2009;Zhang and Rajagopalan, 2010), specifically, when performance is measured in terms of longevity, such as the number of years that the firm has been operating, instead of financial terms (annual profit average). This could imply that in small family firms, ECEO DMCs are more relevant to firm survival than financial indicators.
As Friedman et al. (2016) study findings show that CEOs may be more influential in small entrepreneurial firms' capacity to adapt to a changing environment. Sensing the environment, seizing and combining external knowledge, and transforming organizational resources and capabilities over time may be more crucial to smaller family firms' ability to develop new opportunities for growth and thus to stay in the market and survive in the first years.
Hypothesis 2 proposed that the family firm governance structure will positively moderate the relationship between ECEO DMC levels and firm performance. The findings reported in Figure 2 reveal that family firm governance structure strengthens the positive relationship between the level of an ECEO's DMCs and firm performance, for this hypothesis 2 is confirmed. A standardized regression weight of 0.69 indicates that family involvement has a very considerable influence over this relationship.
In relation to our findings that family firm governance structure strengthens the relationship between the level of an ECEO's DMCs and firm performance, we have two important issues to discuss. First, the positive and significant relationship observed in the results lead us to argue that when doing research with small firms, scholars should consider the implications of how small family-firm governance structure is measured. It is often common in family firm research to only account for family members who formally work for the firm, omitting family members that participate informally or on a part-time basis. Our observed evidence suggests that in small family firms, especially in their early stages, family members generally carry out many tasks without being formally remunerated, but they are highly involved in making decision process. This finding supports Schulze et al., (2003)

study in which researchers
found that when a small number of family members owns and controls the business, such as the founders, their focus is predominantly on the firm's long-term economical sustainability.
Second, this results also contradict those of scholars who argue that family firm governance structure negatively affects performance (Campopiano et al., 2014;Kellermanns et al., 2012;Nicholson, 2008;Schulze et al., 2001Schulze et al., , 2003. However, as acknowledged earlier, some researchers have argued that in some instances, the effects of family firm governance structure might be contingent on individual and organizational characteristics (e.g., type of nepotism, or size and stage of the firm) (Jaskiewicz, et al., 2013;Karra. et al., 2006). Therefore, one explanation is that in early stages of a family firm, i.e., when it is small with only a few family members as employees, the positive influence of family firm governance structure will be greater than any negative influence, but this could change and differ from the relationship found in larger and more mature firms.
Hypothesis 3 tested the antecedent role of an ECEO's MHC on his/her level of DMCs, stating that this relationship will be positive. The model in Figure 2 demonstrates that MHC is positively and significantly related to ECEO's DMCs with a probability less than 0.001 (p < 0.001). Thus, hypothesis 3 is upheld. A standardized regression weight of 0.51 indicates that a ECEO's MHC influences their DMC levels. Statistically, this means that a ECEO's DMCs is improved by approximately 0.51 standard deviation units for every one standard deviation increase in the ECEO's MHC.
This finding indicates that ECEOs of a certain age and having certain levels and types of formal education (graduate studies, preferably an MBA), and with a high level of entrepreneurial experience tend to have higher levels of DMCs, This confirms that skills from different organizational areas could be related to DCs, like R&D, strategic change, investment and valuation techniques, risk aversion, strategic decisions, and expertize-based intuition (Barker and Mueller, 2002;Bertrand and Schoar, 2003;Khatri and Ng, 2000;McDonald and Westphal, 2003;Nadkarni and Narayanan, 2007;Prashantham and Dhanaraj, 2010;Robert Mitchell, et al., 2011;Salas Rosen and Diaz Granados, 2010).
Achieving a higher level of education and/or possessing an MBA should be related with having a greater ability to sense, and seize opportunities and threats, and to transform the assets of a firm in order to sustain its competitive advantage. Education can enhance an individual's cognitive abilities, which in turn will prepare him to couple better with business and environmental changes Bertrand & Schoar, 2003). In this sense, in our literature review related to educational level, we found that higher education level is associated with i) a grea-ter tolerance for ambiguity, which is required on dynamic environments and changes in the firm's strategy; ii) an increased ability to process multiple alternatives, which is extremely necessary for a CEOs/ECEOs in order to sense and evaluate multiple opportunities and; iii) a source of innovation which is needed in order to create, extend, and modify the ways in which firms make a living.
Moreover, future research is needed in order to understand whether or not the possession of an MBA education by an ECEO is essential not only in influencing a greater level of DMCs, as our results shows, but also in specifically showing higher levels of one specific component of the DMCs, the seizing capability.
This list leads one to argue that entrepreneurial experience could be included as a new variable to evaluate the construct of MHC. The results of the present study indicate a clear need for further research, supported by the theoretical definition of DMCs and MHCs (Helfat and Martin, 2015) in conjunction with the current literature on individual experience (Barker and Mueller, 2002;Dearborn and Simon, 1958;Finkelstein and Hambrick, 1996).

Conclusions
To survive in a business environment where change is permanent, small business firms require CEOs able to sense, seize, and transform their organization, abilities often called DMCs. In that sense, this study emphasizes that, in addition to organizational dynamic capabilities, small business firms need to develop and/or strengthen their CEOs DMC in order to respond, adapt, and survive in the market. This study reveals certain characteristics of entrepreneur CEOs (ECEO), e.g., those related to their MHC like age, formal education, and entrepreneurship experience, have a significant impact on their ability to lead their organizations in uncertain and unpredictable business scenarios.
The construct of dynamic capabilities has been extensively explored by strategic management researchers for the last two decades. However, Chirico and Norvquist (2010) observed that only a few studies have focused on dynamic capabilities in family firms, and we might add that none have studied DMCs in these kinds of organizations. Our study therefore adds novel insights to the literature of dynamic capabilities and entrepreneurship by extending this concept to family firms and to understand how the entrepreneurial experience of an ECEO influences his DMCs.
A significant aspect for these kinds of firms is family firm governance structure, either as full-time, part-time, or only occasional participation, family members offer additional support to the ECEO's adaptability efforts. Hence, our findings provide practical implications for practitioners by understanding how the managerial human capital of an ECEO (age, career experience, education, entrepreneurial experience) might influence his DMCs and the strategic change of a firm and even its performance. For instance, individuals aged around 50 and with an MBA have greater chances to positively contribute to the development or strengthening of organizational dynamic capabilities. we have found some evidence that indicates, although not conclusively, that this is the optimal range for an ECEO to exhibit a greater level of DMCs. On the other hand, ECEOs/CEOs that are very young or very old will tend to exhibit lower levels of DMCs, therefore should be considerate for firms that operates in more stable environments.
Besides age, there are other aspects of the human capital of an ECEO/CEO that should be considerate when the sensing, or seizing opportunities and threats, or for transforming the resource in a firm is essential for its success. These aspects are an individual´s education and entrepreneurial experience. Regarding to education, there is evidence that indicates that the greater the number of years of formal education that an ECEO have, the greater the chances he will exhibit greater levels of DMCs, and in consequence a greater chance for a better performance of the firm.
For further research, the present study findings raise several questions whose answers would provide greater understanding of family businesses and DMCs. Firstly, most previous research has focused on family members formally involved in the firm, as indicated by Tabor et al. (2018), who have made a call to direct the research agenda toward the study of other types of family members that can influence a family firm. In this sense, the different roles and influences that family members who are not formally working full-time in family firms could have over the firm are not fully understood.
Second, we argue that family members fitting this description could serve as gatekeepers for the family firm (i.e., bring new information and ideas to the family firm from outside) because their part-time or sporadic involvement in the family enterprise could give them the opportunity to be involved with other organizations, even though more studies are needed to expand this finding.
Third, our literature review of DMCs indicates that scholars have focused their efforts on testing only one of the underlying managerial resource of DMCs, namely that of MHC.
However, much remains unknown about the other types of resources, such as managerial social capital, managerial cognition, and entrepreneurial experience.
Finally, some limitations of the present study should be taken into account. First, the cross-sectional nature of the study means that the conclusions are tentative; reverse causality might be present. Second, firm performance could be measured as a growth rate or profit average, even though in the present study was measured as firm longevity confirming how Dynamic Managerial Capabilities (DMC) impact on firm sustainability. Third, the sample study of this study is entirely from Mexico, which can limit the transferability of our findings.
