1. Introduction
Despite extensive empirical research on investment efficiency, the existing literature usually considers that variations in capital structure are mainly justified by firm, industry, and market-level characteristics (
Myers and Majluf 1984). From the perspective of the agency theory, prior research in this field has largely ignored managerial effects on corporate decisions, assuming that managers follow the same objectives (
Andreou et al. 2015). However, according to the upper echelon theory, managers are not homogeneous (
Hambrick and Mason 1984), and individual differences in personal managerial styles can lead them to make dissimilar corporate decisions. In this regard, a recent body of literature has shown the consequences of managerial ability on firm performance (
Bertrand and Schoar 2003), earning quality (
Demerjian et al. 2013), accounting conservatism (
Ahmed and Duellman 2013), accruals (
Dejong and Ling 2013), and voluntary disclosure (
Bamber et al. 2010).
Investment decisions are among the most important corporate decisions that managers can make due to the efficiency in the allocation of capital affects the growth and productive capacity in the economy. Despite the growing research on investment efficiency determinants, the relevant role of individual managerial behavior in corporate investment practices has largely been ignored. Therefore, in this paper we hypothesize an association between managerial ability and investment efficiency. We argue that managerial ability is behind firms’ financial policies and suggest that able managers play a significant role in explaining efficient investment behavior.
Managerial abilities and their influence on investment decisions are even more relevant in the banking industry due to the large informational asymmetries, opaqueness, and complexities existing in the financial sector (
Levine 2004). Bank managers face many types of risk (
Nichols et al. 2009). According to the upper echelon theory, in complex situations, managers’ decisions can be greatly affected by their personal experiences and values. Therefore, in financial firms, more able managers may make better decisions by having improved techniques for evaluating both existing and potential business, and they may better take strategic plans, available resources, bank industry characteristics, and the macroeconomic environment into consideration (
Gan 2015). In this respect,
Andreou et al. (
2015) show that more talented managers create greater liquidity and therefore attain better performance. Hence, we assume that more able bank managers will select better investment projects and will implement them more ably, with the objective of gaining greater investment efficiency.
Using a large bank sample from nine countries, we hypothesize a relationship between managerial ability and investment efficiency. We also expect that this association will be negative (positive) in those banks operating in settings predisposed to overinvestment (underinvestment). We build our hypotheses based on the upper echelon theory and the resource-based view, which suggest that managers’ characteristics affect how they interpret corporate situations, and therefore have an impact on their financial decisions (
Holcomb et al. 2009).
The interest of the analysis period resides in the time frame that we analyzed, which is closely linked to the previous economic recession on which information is available. In relation to the geographic distribution of the sample, this represents the reality of large banks at the international level, a bias that must be present in any analysis. Their joint consideration allows the study to control the diversity of managerial ability and the favorable or unfavorable predisposition to investment linked to different institutional contexts, enriching the results that would be obtained with a sample from a single country.
Our paper is inspired by
Bertrand and Schoar’s (
2003) work, who noted the influence of managers on corporate behavior and performance, as well as the work by
Demerjian et al. (
2013), who studied the significant consequences of managerial ability on efficiency. Given the specificity of financial firms, we cannot infer from these studies whether managerial abilities affect investment decisions in banks. In addition, although most researchers in this field traditionally focus on specific managerial characteristics, such as tenure or education, to measure managerial ability, we follow
Demerjian et al. (
2012). In accordance with previous research, the model used for testing investment efficiency is based on
Biddle et al. (
2009). We examine the relationship between managerial ability and three different types of investments that demand significant resources: capital expenditure, R&D expenditure, and acquisition expenditure. In the second step, we analyze whether managerial ability is related to increased (reduced) investment in banks prone to underinvesting (overinvesting).
Our evidence indicates that, after controlling for bank and country-specific institutional factors, managers’ abilities are an economically relevant determinant of investment efficiency in banks. Overall, the results indicate that when firms have a predisposition towards underinvestment, higher managerial ability is shown to increase levels of R&D, acquisition expenditures, and total investments. In contrast, when firms have an increasing tendency towards overinvestment, managerial ability tends to reduce the levels of R&D and acquisition expenditures, as well as total capital investments. We obtain similar evidence by using other investment measures.
We make several contributions. First, we extend previous research on managerial ability (
Bertrand and Schoar 2003;
Demerjian et al. 2013;
García-Sánchez and García-Meca 2018) by showing that able managers in financial firms contribute to better investment efficiency. This paper also covers the gap in the literature that calls for a further exploration of the individual roles played in financial firm decisions, and it is the first empirical study to investigate this association in the international financial industry. Second, we provide better knowledge about the role played by individual managerial characteristics in financial decisions. Therefore, we contribute to the growing literature showing that individual able managers affect corporate decisions beyond firm, industry, and market determinants. Third, this paper has relevant macroeconomic and firm implications given that investment is highly relevant in the growth of countries and the return on investment capital (
Biddle et al. 2009). It also highlights the limitations of governance mechanisms in terms of aligning managers’ and shareholders’ preferences (
Malmendier et al. 2010). Finally, there are relevant policy-related implications in this paper for bank supervision regulators and policymakers, as we show managerial ability to be a performance indicator.
3. Data and Empirical Setting
3.1. Sample
The sample for analysis is composed of 877 observations, corresponding to more than 150 banks from 9 countries, and it spans the time period from 2004 to 2010. We obtained the financial data from the Compustat and EIRIS databases, and the Spencer & Stuart Board Index provided the corporate governance data.
Initially, we accessed economic and financial information from 524 listed banks through the Compustat database. Then, we eliminated from the sample 344 banks with no information on their board composition in the Spencer & Stuart Board Index. Finally, we discarded 21 more banks which had no information on their ethical commitment in the EIRIS database. After this process, we obtained a sample composed of 159 financial entities from Canada, Spain, the UK, Germany, the Netherlands, France, Italy, Sweden, and the USA. This made it possible to take the different banking sector regulations related to national characteristics into account. The time period considered is 2004–2010, although no information is available for some years, resulting in an unbalanced panel database of 877 observations.
Regarding the sample distribution (
Table 1), we observe that more than 45% of companies are from the USA and more than 20% are from the UK.
3.2. Dependent Variable
Investment is an extremely relevant firm activity, having the same objective as other corporate practices, namely to maximize bank value. Inefficient investment decisions affect shareholder wealth because they not only waste significant resources but also result in negative impacts in the long term.
In our paper, ‘investment’ is a measure of future investment in both capital and non-capital goods. Following
Biddle et al. (
2009), we measure total investment as the addition of capital, R&D, and acquisition expenditures, minus cash receipts from the sales of property plant, and equipment, scaled by average total assets.
Nowadays, with the advent of internet banking, the growth of channels to access online bank services has exploded. These entities undertake greater investment in R&D policies that favor the growth of these new channels rather than traditional investment in tangible goods. In addition, in order to increase their size and expand their presence in other countries, banks acquire financial entities located in their geographic objective. Thus, we have analyzed these different typologies of investment independently. In this regard, Capital_Invest reflects the level of capital expenditure, R&D_Invest, the level of R&D expenditure, and Acqui_Invest, the level of acquisition expenditure. By using different investment measures, we can identify the effect of managerial ability on bank decision-making. In addition, banks are currently reorienting their capital investment policies towards R&D and acquisition expenditures that allow them to operate in digital and other geographic areas.
Theoretically, investment opportunities with positive present net values are undertaken by banks. However, in the real world, financial market imperfections do exist, and underinvestment and overinvestment occur. Hence, we explore the influence of managerial ability on investment efficiency, considering that a bank may deviate from its optimal level of investment influenced by managerial ability levels. To carry out this exploration, we consider that advanced managerial ability leads to improved capital investment efficiency when banks are more vulnerable to agency problems, i.e., reducing (increasing) investment when there is a tendency to overinvest (underinvest). Consistent with
Biddle et al. (
2009), we categorized banks into deciles according to their cash and leverage levels. Leverage is multiplied by −1 before ranking, so that it can be interpreted the same way as cash balance. Deciles constructed in this way are rescaled to range from 0 to 1. We then develop a new variable,
Over_Invest, equaling the mean of the ranked values of the two partitioning variables. This variable increases with the tendency to overinvest. The underlying rationale for using these two criteria is that the levels of free cash flow and leverage may indicate agency problems (
Jensen 1986;
Myers and Majluf 1984).
3.3. Managerial Ability
Demerjian et al. (
2012) define managerial ability by calculating a data envelopment analysis (DEA) score that reports whether managers use their firms’ resources in an efficient way. They estimated firm efficiency (DEA score) within industries, comparing firm sales and several inputs used by firms: cost of goods sold, net property, selling and administrative expenses, plant and equipment, net R&D, net operating leases, purchased goodwill, and other intangible assets. Later, they regressed the DEA score in order to obtain the residuals, i.e., values that identify the efficiency attributable to managers. This efficiency measure can be applied to all firms but, according to
Leverty and Grace (
2012), it is necessary to use a specific measure of firm efficiency for a single industry.
We adopt this strategy and define managerial ability using a two-stage DEA approach. First, we use DEA to create an efficient borderline that determines the relative efficiency of a firm by measuring the resources (inputs) used to obtain revenues (outputs).
Outputs identify the monetary volume of deposits, loans, and other investments, as well as the interest income generated by loans and other investments (Deposits, Loans, Investment, and IntIncome). As inputs we include tangible and intangible acquired assets. The first acquired asset is represented by the net PP&E value (PPE). The second is measured by the net value of intangible assets that incorporates all the investments in intangibles, especially goodwill for those banks that have acquired other financial entities (Int). We also incorporate labor costs in order to represent the importance of personnel in the financial industry (Labor) and the interest expenses paid to banks for deposits (IntExp). In addition, we include operating rental expenses in order to incorporate those bank offices that are excluded as assets but contribute to generating revenues (RentalExp).
The DEA model maximizes Equation (1) for each decision-making unit in relation to the rest of decision-making units in the group by changing the weights u and v.
In
Table 2, we present the mean of the DEA score for each year as well as the number of efficient banks in absolute and relative terms. It is possible to observe that efficiency is relatively stable in all the periods, at around 75%. In contrast, there is significant variance in the number of efficient banks.
Second, to isolate firm effects on managerial ability, we run a tobit regression mode—Equation (2)—in which the DEA measure is determined by those firm characteristics expected to aid (size, market share, free cash flow, and firm age) or hinder (bank regulatory environment) management’s efforts. We suggest that in banks with higher market value, managers will be more effective when negotiating with customers and suppliers. Similarly, in those banks with more available cash, positive net present value projects can be easily obtained by managers. We also expect the life cycle of the bank and the start-up costs of investments to have an influence. Finally, following
García-Meca et al. (
2015), we consider the influence of the banking regulatory environment.
The residuals of Equation (2) identify the level of efficiency attributable to managers and comprise the managerial ability variable (Ability).
3.4. Models Testing Managerial Ability and Capital Investment Efficiency
In this section, we investigate whether high managerial ability is able to improve investment efficiency when banks are more vulnerable to agency problems, i.e., reducing (increasing) investment when there is a tendency to overinvest (underinvest). Consistent with this approach, we pose a model [1] which is designed to test the association between managerial ability and investment levels:
where:
Investment is the level of total capital investment equal to the sum of capital expenditure, R&D expenditure, and acquisition expenditure minus cash receipts from the sale of PP&E;
Capital/R&D/Acqui_Invest is the level of capital, R&D, or acquisition expenditure;
Ability measures managerial ability and is created by the residuals from the DEA score regression that identify the level of efficiency attributable to the managers;
Size is measured by the natural log of total bank assets;
MtB denotes the growth opportunities measured as the ratio of the market value of total assets to the book value of total assets;
Loss takes the value of 1 if net income before extraordinary items is negative and 0 otherwise;
SdSales is the standard deviation of the sales scaled by average total assets over the previous five years;
SdInvestement is the standard deviation of investment over the previous five years;
Op_Cahs_flow denotes the operating cash flows divided by sales;
Slack is the ratio of cash to PP&E;
Dividend is an indicator variable equal to 1 if the firm paid dividends and 0 otherwise;
Zscore = 0.033 *earnings before extraordinary item/total assets + sales/total assets + 0.014 *retained earnings/total assets + 0.012 *(working capital/total assets) + 0.006 *(market value of common stock/total liabilities);
Tangibility is PP&E scaled by total assets;
Kstructure is the debt (long-term) scaled by the addition of long-term debt and the market value of equity;
Board denotes the level of independence, diversity, and financial expertise of the board;
IP is the level of investor protection by country; and
Regulation is the strength of bank industry characteristics.
Model [2] incorporates the variable
Over_Invest, which indicates the tendency to overinvest as well as the interaction between
Over_Invest and managerial ability. The value of this variable increases in line with the tendency to overinvest. In this model,
β1 shows the influence of managerial ability on investment levels when underinvestment is most likely, i.e., when
Over_Invest is 0,
β3 measures the incremental effect of managerial ability on investment levels, and the sum of
β1 and
β3 measures the overall influence of managerial ability when
Over_Invest is not 0. If more able managers make more efficient investment decisions, we will observe a positive
β1 and a negative
β3.
In this model, we control for several variables that influence investment decisions. Among these, sales volatility and return on assets and loss indicate firm performance and profitability. Both firm size and the market-to-book ratio represent growth opportunities. The cash flow to sales ratio, cash to PPE ratio, dividend, the possibility of bankruptcy, and capital structure suggest free cash availability, the degree of financial constraint, and the magnitude of agency problems, respectively. In addition, we isolate the influence of bank and country characteristics (see
García-Meca et al. 2015 for a description of the measures) and use fixed effects (
Year_dummies).
In relation to firm characteristics, we have included the board of directors measure (Board), considering the independence, diversity, and financial expertise of board. The indicator IP represents the country level of investor protection. The effect of the banking regulatory system is represented by the factor Regulation. We have used different bank characteristics to define the strength of the banking industry: industry size, banking activity and ownership restrictiveness, prompt corrective action, power of official supervisory systems, and deposit insurance design. We expect that with higher regulation and investor protection levels, banks will carry out efficient investment, as in this environment investors have greater information available on bank transactions. Moreover, the strongest boards have greater power in monitoring managers’ investment decisions.
We estimate both models by using the generalized method of moments (GMM), designed by
Arellano and Bond (
1991), which allows us to control for endogeneity problems by using instruments.
4. Results
Table 3 displays the descriptive statistics of the full sample and of low versus high ability groups. In the first two columns of
Table 3, the mean (standard deviation) of total investments is 0.231 (±0.297). Regarding the components of total investments, the mean (standard deviation) of R&D is 0.694 (±0.335), the mean (standard deviation) of acquisition expenditure is 0.224 (±0.118), and the mean of capital expenditures is 0.007. A mean of zero for capital expenditures indicates that less than 50 per cent of the firm-year observations reflected capital investment during the sample period. The managerial ability score has a mean (standard deviation) of 0.798 (±0.026).
The other columns of
Table 3 report the descriptive statistics by low versus high managerial ability groups, using the industry median of the managerial ability score as a benchmark. They show that the high-ability group has higher values for total investment, R&D, and acquisition expenditures, and lower values for capital expenditures, compared to the low-ability group.
Table 4 presents the Pearson correlations among selected variables. While capital expenditures are negatively correlated with managerial ability, the other types of investment and total investment are shown to be positively correlated with the ability variable.
Here, we reflect on the results for model [1] (
Table 5, Panel A), in which we investigate the association between managerial ability and actual investments without conditioning firms’ tendencies towards overinvestment or underinvestment. Managerial ability is positively associated with total investments and the three components of total investments (capital expenditures, R&D, and acquisition expenditures).It is not significant, however, for capital investment. More concretely, managerial ability has a significant statistical impact on total and R&D investment with a confidence level of 99% and on acquisition expenditures at 95%. These results are in line with
Chemmanur et al. (
2009), who find that better managers may select better firm projects, achieving higher levels of capital expenditures as well as investments in R&D. Results are related with
García-Sánchez and García-Meca (
2018), who also noted that managerial abilities play a significant role in the quality of financial reporting in banks, and that capable bank managers are less likely to manage earnings opportunistically. Similar studies also found that superior operating ability leads to implementing operating decisions more effectively (
Demerjian et al. 2013;
Choi et al. 2015).
We tabulate the results for model (
2) (
Table 5, Panel B), analyzing the association between investment and managerial ability conditioned by firms’ tendencies towards overinvestment or underinvestment. We find evidence that managerial ability influences total, R&D, and acquisition investments when firms are most likely to underinvest (β
1). Again, we do not find the same effect on capital expenditures when firms are predicted to underinvest. Using total investments as an example, an increase of one standard deviation in managerial ability results in an increase of 3.040 in total investments among firms that are likely to underinvest. Furthermore, the results show that as the tendency to overinvest increases, higher managerial ability tends to reduce total investments, R&D, and acquisition expenditures (β
3). The result is not statistically significant for capital expenditures.
Overall, the results indicate that when firms have a predisposition towards underinvestment, higher managerial ability is shown to increase the levels of R&D, acquisition expenditures, and total investments. When firms have an increased tendency towards overinvestment, managerial ability tends to reduce the levels of R&D and acquisition expenditures as well as total capital investments. However, neither result can be generalized with regard to capital expenditures.
The estimated coefficients of the control variables are consistent with prior research, and thus, larger (Size) and growing firms (Mtb) with more operating cash flow are more likely to increase investment levels, while distributing dividends (Dividend) negatively affects investment levels. The likelihood of bankruptcy (Zscore), a capital structure with a higher ratio of leverage (Kstructure), and higher volatility in sales (SdSales), or negative results (Loss), are negatively associated with investment levels. In relation to control factors, firms located in countries with the strongest bank regulations (Regulation) and investor protection rules (IP) carry out more efficient investment. Independence, diversity, and board expertise (Board) are relevant in monitoring investment decisions.
Robustness of Resuzlts
In our robustness tests, we measure investment as abnormal investment. We refer to this proxy as
abn_Investment, and it is calculated as the residuals from a one-year regression of annual bank future capital investment on annual current sales growth. Thus, banks with large positive (negative) residuals will demonstrate overinvestment (underinvestment) practices. This regression is estimated in time-series fashion, as follows in Equation (3):
In addition, we have considered the following: abn_Capital_Invest, the abnormal level of total capital expenditure, proxied by the residuals from the regression of a firm’s total capital investment on lagged sales growth; abn_R&D_Invest, the abnormal level of R&D expenditure, proxied by the residuals from the regression of a firm’s R&D expenditure on lagged sales growth; and abn_Acqui_Invest, the abnormal level of acquisition expenditure, proxied by the residuals from the regression of a firm’s acquisition expenditure on lagged sales growth.
We reflect the results of model [1] (
Table 6, Panel A), in which we investigate the association between managerial ability and abnormal investments without conditioning firms’ tendencies towards overinvestment or underinvestment. We observe a positive influence of managerial ability on total investments and on the three components of total investments (capital expenditures, R&D, and acquisition expenditures).
We also test the association between managerial ability and abnormal investment levels conditioned by firms’ tendencies to overinvest and underinvest. Panel B of
Table 6 displays the results. Specifically, when firms are most likely to underinvest (β
1), abnormal R&D, abnormal acquisition expenditures, and abnormal total capital investments increase with higher managerial ability. Managerial ability tends to reduce the abnormal levels of total investments, R&D, and acquisition expenditures as firms’ tendencies to overinvest increase.
Taken together, the earlier association tests, without conditioning firms’ tendencies towards overinvestment or underinvestment, show that higher managerial ability generally leads to greater investment. More importantly, the conditional association tests reveal that when firms are very likely to underinvest, higher managerial ability has a tendency to increase R&D and acquisition expenditures but not capital expenditures. Managerial ability also tends to increase abnormal R&D, abnormal acquisition expenditures, and abnormal capital investments when firms have a higher tendency to underinvest.
When firms’ tendencies to overinvest increase, higher managerial ability reduces R&D and acquisition expenditures but not capital expenditures. However, higher managerial ability is also shown to reduce abnormal R&D, abnormal acquisition expenditures, and abnormal capital expenditures when firms’ tendencies to overinvest are high. The above results provide evidence in line with the prediction that managerial ability can improve capital investment efficiency and alleviate agency problems.
5. Concluding Remarks
The relevant role of individual managerial behavior in corporate investment practices has largely been ignored. Our objective is to analyze the association between managerial ability in banks and three different types of investments that demand significant resources: capital expenditure, research and development (R&D) expenditure, and acquisition expenditure. We also analyze whether managerial ability is related to increased (reduced) investment in banks prone to underinvestment (overinvestment).
Using data on banks from nine countries over the period 2004–2010, we quantify managerial ability following
Demerjian et al. (
2012) and calculate a data envelopment analysis (DEA) score to estimate how efficiently managers use their firms’ resources.
The results indicate that when firms have a predisposition towards underinvestment, higher managerial ability is shown to increase the levels of R&D, acquisition expenditures, and total investments. In contrast, when banks have an increasing tendency towards overinvestment, managerial ability tends to reduce the levels of R&D and acquisition expenditures as well as total capital investments. Thus, our findings evidence that more able bank managers select and implement investment projects more efficiently and confirm the upper echelon theory and resource-based view, which suggest that managers’ characteristics affect financial decisions. Results are in line with previous papers that show that managerial ability increases investment efficiency (
Demerjian et al. 2013;
García-Sánchez and García-Meca 2018).
Investigating the effects of managerial abilitiy on firm policies, including investment policies, is highly relevant because managers can make decisions that reduce bank value, thereby affecting the economy of countries. Thus, the evidence from this study can help standard-setters and regulators to better understand bank business practices and investment behavior in light of managerial abilities. Given that research on managerial ability in banks is still in its early stages, it might be worth studying the effect of specific managerial characteristics, such as education, risk aversion, social connections, or financial experience, on bank financial and reporting choices in greater depth. In addition, from a practical point of view, our results suggest that manager selection processes are especially relevant in order to quantify managerial ability since this attribute is essential to avoid agency problems associated with managers´ individual preferences.
However, this study is subject to several limitations, especially the time period and sample distribution that have been taken into account to interpret our results. Therefore, future research could focus on specific countries in order to accept or reject our research hypotheses in specific countries like Islamic countries or those with emerging economies or geographic locations where the institutional environments are quite different in terms of cultural or religious values, among others. In addition, the economic recession associated with the consequences of COVID-19 could be an interesting framework for future analysis in pre and post economic recession periods.
