Board diversity and risk-taking of family firms: Evidence from China

Using a sample of more than 1,500 Chinese listed firms over four years of observation (2015–2018), this study examines the effects of family ownership and certain features of board diversity (gender diversity, age diversity, and education diversity) on the risk-taking of Chinese listed firms. First, a two-way fixed effects regression model is proposed. Then, this study finds that the examined Chinese family firms’ risk-taking, which is measured by their Z-scores and innovation intensity, is lower than that of the nonfamily firms. This result confirms the prediction of social-emotional wealth theory. Second, a diversity index is formulated to summarize the above three dimensions of board diversity. By regressing risk-taking measures on these board diversity features, this study finds that firms with less-diverse boards take more risks. Finally, the effects of the interaction between family ownership and board diversity are explored. The results reveal that the examined dimensions of board diversity have significant influences on risk-taking: family firms with lower levels of board diversity generally take more risks than those with higher levels of board diversity. Our study contributes to the literature on risk-taking of family business and has important practical implications for motivating family business innovation in China.

Marshallian labour market pooling: Evidence from Italy

This paper employs a unique Italian data source to take a comprehensive approach to labour market pooling. It jointly considers many different aspects of the agglomeration — labour market relationship, including turnover, learning, matching, and hold up. It also considers labour market pooling from the perspective of both workers and firms and across a range of industries. Overall, the paper finds some support for theories of labour market pooling, but the support is weak. Specifically, there is a general positive relationship of turnover to local population density, which is consistent with theories of agglomeration and uncertainty. There is also evidence of on-the-job learning that is consistent with theories of labour pooling, labour poaching, and hold up. In addition, the paper provides evidence consistent with agglomeration improving job matches. However, the labour market pooling gains that we measure are small in magnitude and seem unlikely to account for a substantial share of the agglomeration benefits accruing to Italian workers and firms.

Production functions and productivity of family firms: Evidence from the S&P 500

This paper examines whether the higher profitability and valuation of family firms is related to differences in production technologies and production efficiency. Using data on S&P 500 manufacturing firms, we find that family firms are more productive than comparable non-family firms. Furthermore, our results show that the production technologies of family and non-family firms do not differ per se, thereby suggesting that the differences in the level of production output are caused by higher production efficiency of family firms. These findings indicate that the superior performance of family firms is related to their more efficient use of labor and capital resources.     

The impact of ADR activity on stock market liquidity: Evidence from Latin America

This paper examines the impact of ADR activity on liquidity of four major Latin American stock markets. We construct a measure of ADR activity in U.S. markets for a sample of ADRs trading during January 2003–December 2010, which is subsequent to the financial liberalization episodes and currency crises that shocked emerging markets in the 1990s. The sample lists 164 depositary receipt programs (Levels I, II, and III): 16 from Argentina, 81 from Brazil, 19 from Chile, and 48 from Mexico. Using System GMM methods to handle the potential effects from stock market development on economic growth and ADR issuance, we find that higher ADR turnover in U.S. markets has positive effects on domestic market turnover, particularly for issuance of exchange-listed (Levels II and III) ADRs. This positive relationship is not a statistical artifact created by the global financial crisis of 2008.     

A reexamination of the market efficiency hypothesis: Evidence from an electronic intra-day,inter-dealer FX market

Researchers acknowledge that the evidence of autocorrelation (price dependency) in daily/weekly asset returns provides no conclusive evidence against the market efficiency hypothesis since the holding period of actual speculative positions may be less than a day. Using a high frequency (up to one hundredth of a second), transaction-based, electronic foreign exchange (FX) brokerage data set, we show that dealers in this market tend to close their speculative positions in less than a minute. We provide evidence that there is a significant negative autocorrelation in the rate of return on DM/USD exchange rate. However, when we sample data at frequencies shorter than a minute, profits are infeasible for two reasons: (1) the structure of the autocorrelation pattern is not consistent enough; (2) the largest potential speculative profit derived from the autocorrelation pattern is smaller than the regulated tick size. Our results support the market efficiency hypothesis as dealers have evidently engaged potentially profitable speculation based on price dependency.     

The impacts of family involvement on R&D investment intensity in firms: Evidence from China

Drawing on the perspective of socioemotional wealth, this paper explores the types of family involvement in family firms and their impacts on R&D investment intensity. Using data from the forecasts issued by A-share family firms listed on Chinese stock markets between 2008 and 2019, the study finds that the separation of ownership and control is negatively associated with R&D investment intensity in non-high-tech firms, whereas potential gains of socioemotional wealth from R&D activities by high-tech firms produce a positive influence that offsets the negative impact of the separation of ownership and control on R&D investments. It reveals the importance of gains of socioemotional wealth. In contrast to the separation of ownership and control, family involvement in management is negatively associated with firms’ R&D investment intensity in both high-tech firms and non-high-tech firms. Our results capture the diversity of family members’ identity recognition, which leads to family members’ different evaluations of the potential gains and losses of socioemotional wealth. Overall, the distinction between high-tech family firms and other family firms is shown to be significant, as is the distinction between the impacts of different types of family involvement.

     

Competition and optimal departures from stock market value maximization by firms

Models of firm decisionmaking under uncertainty have done a good job of explaining the implications of spanning and competitive behavior. An opportunity set dominance argument under these conditions predicts the optimality of stock market value maximization. This paper reexamines the firm's choice rule assuming competitive behavior but without the restrictive assumption of spanning. The resulting rule breaks into two parts consisting of the traditional market value maximization component plus another term depending on the welfare effect of a change in the contract structure. Necessary and sufficient conditions, including spanning, for this term to be zero are derived.     

Transaction costs and market efficiency: Evidence from commission deregulation

This study analyzes the impacts of explicit transaction costs on weak-form market efficiency within the context of the brokerage commission deregulation in Japan in October 1999, which led to lower commission rates across the market. Applying two alternative statistical tests to both daily and weekly data, we find that return randomness (unpredictability) increases significantly for stocks listed in Japan, but not for the Japanese stocks dually listed in the United States, which are immune to the deregulation. These results suggest an inefficiency loss or an efficiency gain in the Japanese equity market following the deregulation, insofar as randomness proxies for efficiency.     

Labor market rigidities and economic efficiency: Evidence from Spain

In the 1990s, Spain approved two labor reforms aimed at reducing the unemployment level and its volatility. Overall, these reforms involved two measures designed to induce firms to meet their labor needs via adjustment of permanent positions: restricting the use of temporary workers and reducing the amount of severance payments. This paper empirically assesses the impact of these reforms on the allocative efficiency of the labor input employing Petrin and Sivadasan's (2011) value of the marginal product-marginal cost gap methodology. We find a statistically significant increase in within-firm permanent labor gaps following the reforms. These results suggest that restrictions on the use of temporary workers (increasing the probability of hiring fragile workers for permanent positions), when coupled with uncertainty about enforcement of reduced severance payments, could more than offset the reduction in severance payments; hence, the net effect of the reforms could be to increase adjustment costs for permanent positions.     

Default rates in the loan market for SMEs: Evidence from Slovakia

Financial markets in emerging economies are often perceived as more risky than those in developed countries. We investigate whether this is true for loans to SMEs using a unique unbalanced panel of nearly 700 loans made to SMEs in Slovakia between 2000 and 2005. Several probit and panel probit models show that liquidity and profitability factors are important determinants of SME defaults. Moreover, we find that indebtedness significantly increases the probability of default. Liability as proxied by the legal form of SMEs has important incentive effects. Finally, there exist significant differences between sectors. We show that default rates and factors converged to values found in developed financial markets.     

Inventory management effects,isolated: Evidence from the federal funds market

The federal funds market is highly competitive, has uniform information, and does not have most order-processing cost components of equity markets. Hence, it provides an opportunity to study the effect of inventory management on the bid-ask spread in an isolated fashion. Using a unique data set of daily borrowing and lending federal funds quotes posted by a large commercial bank, we find that the bank maintains a fairly constant bid-ask spread throughout a two-week reserve maintenance period. It acts similarly to a market maker facilitating flow of funds between depository institutions throughout the reserve maintenance period. The bank becomes more active toward the end of the period. In particular, on settlement Wednesday it increases the bid and ask quotes relative to the effective federal funds rate in an apparent attempt to manage its reserve inventory and satisfy its own reserve requirements.     

Stock returns and volatility: Evidence from the Athens Stock market index

This paper investigates the volatility of the Athens Stock excess stock returns over the period 1990–1999 through the comparison of various conditional hetero-skedasticity models. The empirical results indicate that there is significant evidence for asymmetry in stock returns, which is captured by a quadratic GARCH specification model, while there is strong persistence of shocks into volatility.     

The relationship between entrepreneurial orientation and speed to the market: The case of incubator firms in Norway

Incubators and incubator firms work to promote the development and commercialization of technology and products. This study shows that entrepreneurial orientation can help achieve this aim. Using survey data from incubator firms, we show that entrepreneurial orientation has a statistically significant positive effect on ability to bring technology and products quickly to the market. This finding is important for managers of incubator firms and managers of incubators alike as they have a common interest in speed to the market. An implication of our study is that managers of incubators should try to enhance the entrepreneurial orientation of the incubator firms.     

The impact of monetary policy on stock market bubbles and trading behavior: Evidence from the lab

We investigate the effect of monetary policy on stock market bubbles and trading behavior in experimental asset markets. We introduce the possibility of investing in interest bearing bonds to the widely used laboratory asset market design of Smith et al. (1988). Treatment groups face a variable interest rate policy which depends on asset prices, while control groups are subjected to a constant interest rate. We observe a strong impact of our interest rate policy on liquidity in the stock market but only a small impact on bubbles. However, we find that announcing the possibility of reserve requirements significantly reduces bubbles.     

The housing market effects of discrete land use regulations: Evidence from the California coastal boundary zone

The California coast line borders some of the most beautiful and expensive land in the entire world. The California Coastal Commission was created in 1976 to protect the coast line and to regulate land use within the coastal boundary zone. This well defined regulatory boundary offers a unique opportunity to study the consequences of land use regulation on nearby housing located in the same political jurisdiction. Using two different geocoded data sets, we document gentrification within the boundary and discuss possible explanations for these patterns.
