How useful are signals? A micro-structure analysis

We analyze how the market processes a signaling event by studying a sample of self-tender offers, events often viewed as signals of firm value. By examining changes in the degree of informed trading, we find asymmetric information costs fall at announcement, remain low throughout the event, and increase at offer expiration. By 1 month following expiration, informed trading returns to a level not significantly different from that prior to the offer. Higher risk firms have significantly larger declines in information asymmetry during the offer. Increases in information asymmetry persist 1 month following expiration for firms with lower pre-offer informed trading.

Investment and dynamic DEA

A dynamic version of data envelopment analysis (DEA) is developed in the present paper. Our model introduces investment in traditional DEA and imposes intertemporal cost minimization. Adding an intertemporal adjustment constraint into the cost minimization problem, we derive the relation between the DEA variables of the variable cost function and those of the primary production frontiers’ coefficients. The augmented DEA model can be solved using standard linear programming. This dynamic framework enables computing the production frontiers, measuring the productive efficiencies and evaluating the potential economies all in the presence of adjustment costs.

The geography of new firm formation: Evidence from independent start-ups and new subsidiaries in the Netherlands

This paper investigates to what extent determinants of the rate of independent start-ups and the rate of new subsidiaries are different. Using a regional database for the Netherlands over the period 1988–2002, we investigate the impact of two types of agglomeration effects, localization and urbanization, while controlling for a range of economic variables. We find urbanization economies to be particularly important for the creation of new subsidiaries while localization economies are more important for the creation of independent new ventures. Finally, the effect of agglomeration variables is found to be stronger for manufacturing industries compared to services industries.

Productivity efficiencies in Ukrainian polyclinics: lessons for health system transitions from differential responses to market changes

Ukraine’s recent elections revealed deep divisions between eastern regions, which favored central economic planning, and western regions, which preferred more free market reforms. This study compares polyclinics in Ukraine to see if the inflexibility of Soviet-style planned economies results in lower economic efficiency in eastern regions. Using data from two geopolitical regions, Data Envelopment Analysis (DEA) scores for polyclinic efficiencies are modeled as a function of demographic and economic determinants. Surprisingly, results indicate that polyclinics in western Ukraine are less efficient. Possible explanations, including case mix intensity, responsiveness to local preferences, physician entrepreneurial behavior and a legacy of inequitable funding, are discussed.

Inter-industry differences in layoff announcement effects for financial institutions

This study expands the examination of workforce layoffs by banks to include non-bank financial institutions and explores inter-industry differences in market reactions to layoff announcements. In examining inter-industry differences, we control for variables that influence the market’s reaction to a layoff announcement, such as firm size, the size of the layoff, the reason given for the layoff, and the governance structure of the firm. We provide evidence of inter-industry differences in market reaction to layoff announcements by financial institutions, with banks experiencing more favorable stock-price reactions than other types of regulated firms. These results provide evidence that bank regulation reduces asymmetric information surrounding managerial announcements to a greater degree than the regulation of other types of financial institutions.

Stochastic productivity measurement

Stochastic productivity indicators are defined, and superlative measures of these indicators are derived. It is shown that, in the presence of complete markets or a common-expectations equilibrium, differences in the market values of firms are superlative indicators of cross-sectional productivity differences. Exactness results are used to decompose nonstochastic productivity indicators into a measure of true productivity change and a measure of ‘luck’. The decomposition is illustrated empirically.

The motives of off-the-books entrepreneurs: necessity- or opportunity-driven?

In recent years, it has become common to represent entrepreneurs as either necessity- or opportunity-driven. Drawing upon face-to-face interviews in England with 70 entrepreneurs trading wholly or partially off-the-books, this paper evaluates critically this dichotomous representation. The finding is that squeezing the motives of off-the-books entrepreneurs into one side or the other of this dichotomy not only over-simplifies their rationales since both necessity and opportunity motives are often involved but also obfuscates how their motives change over time. The outcome is a call to replace this either/or depiction with a richer and more nuanced both/and understanding of off-the-books entrepreneurs that recognises their diverse and dynamic motives.

Individual, organizational and environmental determinants of new firm employment growth: evidence from Latin America

New ventures are increasingly playing an important role in Latin American economies. However, little is known about the determinants of new firm growth in this context. The purpose of this study is to gain an understanding of the factors influencing new firm growth in Argentina, Brazil, Mexico and Peru. Individual, organizational and environmental factors are included in an empirical model, which is tested using data collected by face-to-face interviews with 582 entrepreneurs. Different specifications of employment growth and regression approaches are employed. Results suggest that growth strongly depends on the characteristics of the entrepreneur. National environment and firm-related factors are also important factors in determining growth.

Measuring performance in the presence of stochastic demand for hospital services: an analysis of Belgian general care hospitals

Since demand for hospital services is subject to substantial variability, the relationship between uncertain demand, excess capacity, hospital costs and performance should be investigated thoroughly. In this paper a waiting time indicator to proxy hospital standby capacity is incorporated into a multi-product translog cost function for Belgian general care hospitals. The indicator is derived from queuing theory and improves on the conventionally used (inverse of the) occupancy rate. The multi-product stochastic frontier specification allows calculation of cost elasticities and marginal cost of seven hospital departments, as well as the degree of economies of scale and scope and enables identification of differences in efficiency.

A closer look at Black–Scholes option thetas

This paper investigates Black–Scholes call and put option thetas, and derives upper and lower bounds for thetas as a function of underlying asset value. It is well known that the maximum time premium of an option occurs when the underlying asset value equals the exercise price. However, we show that the maximum option theta does not occur at that point, but instead occurs when the asset value is somewhat above the exercise price. We also show that option theta is not monotonic in any of the parameters in the Black–Scholes option-pricing model, including time to maturity. We further explain why the implications of these findings are important for trading and hedging strategies that are affected by the decay in an option’s time premium.

The J-Curve: Evidence from commodity trade between Canada and the U.S.

Several studies in the literature have tried to assess the impact of real depreciation of the Canadian dollar on the Canadian trade balance. They have either relied on the trade data between Canada and the rest of the world or between Canada and her major trading partners. In this paper we consider the trade between Canada and her major trading partner, the U.S. However, unlike previous research, we disaggregate the trade data between the two countries by commodity. We use export and import data over the period 1962–2004 from 152 commodities and the bounds testing approach to cointegration and error-correction modeling and show that real depreciation of the Canadian dollar has short-run effects on the trade balance of two-thirds of the industries. However, only in 50% of the industries, the short-run effects translate into the long-run favorable effects.

The Neuer Markt as an institution of creation and destruction

The market for publicly traded equity is the heart of a modern capitalist system. In particular, the market for newly listed firms is in turn a bellwether for the public equity market because the entry gives firms expanded access to capital, allowing them to emerge and grow. On the other hand, stock markets also serve as an institution to reallocate productive resources from non-surviving to surviving firms. We describe the Neuer Markt—a special segment of the Frankfurt Stock Exchange in Germany—as an institution to foster the creation of new firms and their destruction.

Incorporating correlation regimes in an integrated stressed risk modeling process

The practice of using stress tests to complement Value at Risk (VaR) estimates suffers from some limitations such as the lack of coherence between a statistical risk measure and a subjective one. On the other hand there is a wide consensus that using the same correlation matrix to design various stress tests is not likely to provide an accurate representation of relationship amongst risk factors in periods of market stress. In this paper we introduce a solution to these problems by explicitly considering different correlation regimes and incorporating the result of the stress test to the traditional market risk measurement models.

Firm entry and exit in Italian provinces and the relationship with unemployment

This study investigates the influence of the unemployment rate on firm entry, exit and net entry in Italian provinces. We attempt to explain these market dynamics in six different sectors, including manufacturing, construction, commerce, hotels and restaurants, transport and financial services. We control for other regional factors, such as patenting activity, economic growth, economic welfare, tourism, industrial districts and whether being a major city. Findings indicate that the effects of unemployment on entry and exit are dependent upon the sector under study, but are mainly negative. This suggests a lack of dynamics in the Italian regional labor markets.

Market entry of firms with different legal forms: an empirical test of the influence of institutional factors

Drawing upon institutional theory we develop a conceptual model and investigate the determinants of market entry for worker cooperatives, publicly traded and limited-liability companies. Our results show that formal institutional conditions (i.e., mercantile legislation) influence the start-up choice of entrepreneurs regarding the legal form of their new venture. In addition, we take into account the influence of informal institutional conditions (i.e., local corporate culture) on the market entry rate of firms with different legal structures. Findings show that, while market entry is sensitive to the general economic climate, entry rates of firms with a different legal structure respond differently to the same economic conditions.

Opportunity recognition in technology transfer organizations

The task of recognizing valuable technological opportunities is crucial for the organizations in charge of transferring technology from universities and publicly funded research institutes to the market. Difficulties in understanding the true commercial potential of an application result in failed subsequent commercialization and excess costs of technology transfer. This paper describes how the task of opportunity recognition is performed in five Technology Transfer Organizations (TTOs). The analyzed TTOs had different degree of independence to the structure of the parent and make use of information and competencies acquired through their formal and informal network ties.

Is competition really bad news for cooperatives? Some empirical evidence for Italian producers’ cooperatives

In this paper, we analyse the nature of the relationship between market power and technical efficiency for producers’ cooperatives. More specifically we test two hypotheses: first, we evaluate the extent to which increasing market pressure may help producers’ cooperatives to improve technical efficiency to guarantee positive profits; second, we test whether higher technical efficiency induces producers’ cooperatives to have a larger market share. These hypotheses are tested on a sample of Italian conventional and cooperative firms for the Wine Production and Processing sector, using both frontier analysis and dynamic panel techniques. The results support the hypothesis that increasing market pressure can affect positively the cooperatives′ efficiency, while gains in technical efficiency do not seem to have any impact on the cooperatives’ market share.

A Model for Predicting Outcomes of Sexual Harassment Complaints by Race and Gender

Organizational scholars have studied the impact of sex on sexual harassment outcomes but left unexplored the influences of race. Thus, we use social identity theory to explore the role of race stereotypes and their influences on sexual harassment outcomes. We posit that stereotypes of African-American women tend to be much more negative than those of white women and this serves to marginalize their position both as victims of sexual harassment as well as complainants.

Externalities, efficiency, regulation, and productivity growth in the U.S. electric utility industry

This paper examines the decomposition of total factor productivity growth for firms subject to regulation, given the production of a bad output. The production of good and bad outputs provides benefits and costs to society. Corporate socially responsible firms recognize the cost to society of producing the bad output. The paper separates the production technology and regulation effects from both the scale and technical change components. The paper also examines the measurement and decomposition of productivity growth when not accounting for production of the bad output. Using a 1992–2000 panel of 34 U.S. investor-owned electric utilities, results indicate that improvements in the scale, efficiency change, and technical change components contributed to positive growth. Not accounting for production of the bad output led to, on average, an overestimation of both the rate of productivity growth, and the contributions of scale economies and technical change to changes in productivity growth.

On understanding mutual fund terminations

We examine the determinants of US mutual fund terminations and provide estimates of mutual fund hazard functions. We find that mutual fund termination correlates with a variety of fund specific variables as well as with market variables such as the S&P 500 index and the short-term interest rate. We also test the underlying assumptions of the semi-parametric Cox model and reject proportionality, thus calling to question the use of this model in forming estimates of mutual fund hazard functions. We find that different fund categories exhibit distinct hazard functions depending on the fund’s investment objectives.
