Firm break-up and performance

We analyze the effects of firm break-up on corporate performance. Our analysis is based on a unique data set for a large number of Czech firms spanning the period 1996–2000. We employ a propensity score matching procedure to deal with endogeneity problems. Our results, which are generally in line with the positive effects of firm break-up found in the developed-market literature, show that the initial effects of firm break-up are positive but after a certain point they disappear within a short time. Factors like changes in ownership structure or management are found to be behind later improvements in the performance of firms.     

Technical efficiency in competing panel data models: a study of Norwegian grain farming

Estimation of technical efficiency is widely used in empirical research using both cross-sectional and panel data. Although several stochastic frontier models for panel data are available, only a few of them are normally applied in empirical research. In this article we chose a broad selection of such models based on different assumptions and specifications of heterogeneity, heteroskedasticity and technical inefficiency. We applied these models to a single dataset from Norwegian grain farmers for the period 2004–2008. We also introduced a new model that disentangles firm effects from persistent (time-invariant) and residual (time-varying) technical inefficiency. We found that efficiency results are quite sensitive to how inefficiency is modeled and interpreted. Consequently, we recommend that future empirical research should pay more attention to modeling and interpreting inefficiency as well as to the assumptions underlying each model when using panel data.     

Ownership structure, corporate governance and productive efficiency in China

This paper investigates whether and to what extent ownership structure and corporate governance affect productive efficiency in a sample of 744 publicly listed manufacturing firms in China between 1999 and 2006. The paper finds that firm efficiency, as estimated using stochastic frontier analysis and data envelopment analysis, is negatively related to state ownership while positively related to public and employee share ownership. In addition, the relationship between ownership concentration and firm efficiency is U-shaped, indicating that the largest shareholder may engage in tunneling activities. As the identity of the largest shareholder changes from government, government-controlled legal entity to other types of legal entity, firm efficiency significantly improves. These results provide strong evidence that political interferences have reduced firm efficiency. Moreover, firms with more independent board are more efficient, supporting the argument that board of directors can be an effective internal governance mechanism. Furthermore, provincial market development, a proxy for the strength of external governance mechanism, is positively related to firm efficiency. Overall, the findings illustrate that restructuring state-owned enterprises via improvements in corporate governance has enhanced firm efficiency, but partial privatization without transfer of ownership and control from the state to the public remains a major source of inefficiency in corporate China.     

Ownership,firm size and rent sharing in Bulgaria

Using a unique three-digit firm-level data set of all medium and large manufacturing enterprises in Bulgaria covering the years 1997–1998, we investigate how wages are affected by ownership status, firm size and rent sharing. Our pooled OLS, panel and first-difference TSLS estimates clearly point to ownership structure as an important determinant of both the wage level (for given productivity) and the degree of rent sharing. Rent sharing is very pronounced in state-owned firms but far less pronounced in private domestic and foreign firms. The results strongly confirm the existence of a multinational wage premium. In addition, we find weak evidence of a positive firm size-wage effect and a positive effect of firm size on the degree of rent sharing. If these effects exist, they are often more pronounced in private domestic firms.     

Technical efficiency and firm heterogeneity in stochastic frontier models: application to smallholder maize farms in Ethiopia

This study estimates the technical efficiency measures of maize producing farm households in Ethiopia using stochastic frontier (SF) panel models that take different approaches to model firm heterogeneity. The efficiency measures are found to vary depending on how the estimation model treats both unobserved and observed firm heterogeneity. Estimates from the ‘true’ random effects (TRE) models that treat firm effects as heterogeneity are found to be identical to those from pooled SF models. Those results differ from the ones generated from the basic random effects (RE) models that treat firm effects as part of overall technical inefficiency. The more flexible generalised ‘true’ random effects (GTRE) model that splits the error term into firm effects, persistent inefficiency, transient inefficiency, and a random noise component indicates the presence of higher levels of persistent inefficiency than transient inefficiency. The basic truncated-normal RE model and heteroscedastic RE model yields similar efficiency estimates. The GTRE model predict persistent efficiency measures similar to those from the basic RE and flexible RE model with environmental variables incorporated in the variance function as well as in the deterministic production frontier. These results imply that the RE and GTRE panel models provide reliable efficiency estimates for our data compared to the TRE models. All the estimated SF models generate comparable production function parameters in terms of magnitude and sign. Overall, the results underscore the importance of scrutinising stochastic frontier models for their reliability of analytical results before drawing policy inferences.

     

Firm survival in new EU member states

We analyze firm survival determinants in four new European Union member states (the Czech Republic, Hungary, Poland and Slovakia). We employ the Cox proportional hazards model on firm-level data for the period of 2006–2015. We show that in all four countries, less concentrated control of large shareholders, higher solvency and more board directors are linked with an increased probability of firm survival. However, an excessive number of board directors has a detrimental effect. Firms with foreign owners and higher returns on their assets exhibit better survival chances. Conversely, across countries and industries, larger firms and those hiring international auditors have lower probabilities of survival. A number of specific determinants influence firm survival in different ways, emphasizing the importance of country and industry differences when studying firm survival. We also document that, in an economic sense, determinants associated with the legal form, ownership structure and corporate governance show the most beneficial effects with respect to firm survival.     

Corporate Governance,Investment, and Firm Valuation in Asian Emerging Markets

We investigate the effects of corporate governance and family ownership on firm valuation through investment efficiency in Asian emerging markets. Using 3 years of time series data from the Credit Lyonnais Securities Asia corporate governance score for 10 Asian emerging markets, we find that good corporate governance leads to better or more efficient investment decisions and eventually to higher firm value. We also find that investors reward firms for improvement in corporate governance. The findings do not hold for Asian firms with a family or concentrated ownership structure. The results are not driven by changes in accounting standards in these markets.     

Insider ownership and firm performance in Taiwan's electronics industry: a technical efficiency perspective

This paper applies agency theory to explore the relationship between insider stock ownership and firm performance, particularly in terms of technical efficiency. Insiders are further classified into executives, outside directors, and large shareholders to conduct a detailed study. Six‐year (1996–2001) panel data of 416 Taiwanese listed electronics firms are examined by the stochastic production frontier approach. It is observed that raising the executive‐to‐insider holding ratio first causes a decrease and then an increase in technical efficiency, forming a U‐shaped relationship. However, the board‐to‐insider holding ratio is negatively associated with technical efficiency. The results indicate that equity ownership of top officers in high‐tech firms should be encouraged to enhance firm productivity. Copyright © 2005 John Wiley & Sons, Ltd.     

Estimating Radial Measures of Productivity Growth: Frontier vs Non-Frontier Approaches

In this paper, we propose an alternative econometric framework for estimating and decomposing productivity change that does not require a distribution for inefficiency or the uncorrelatedness between inefficiency and the regressors. We develop our methodology for the input-oriented radial measure of productivity change and establish that this equals the negative of the time change in the log cost function. Our econometric framework is based on a fixed-effects, multiple-output cost frontier, where we decompose productivity change into discrete shifts in the frontier and changes in firm efficiency levels relative to the frontier. We also show that the standard non-frontier specification is nested within our frontier model and thus can produce different estimates of productivity change. Using a panel of twelve US railroads from 1951 to 1975, our estimated cost frontier suggests average annual productivity growth of roughly 0.3 percent, with efficiency change rising then falling over the period. Specification tests reject the non-frontier model, which yields smaller gains in productivity.     

Consistent estimation of the fixed effects stochastic frontier model

In this paper we consider a fixed-effects stochastic frontier model. That is, we have panel data, fixed individual (firm) effects, and the usual stochastic frontier analysis (SFA) composed error.     

Firm efficiency and stock returns

In this paper, we investigate the role of firm efficiency in asset pricing using a sample of US publicly listed companies for the period 1988–2007. We employ non-parametric data envelopment analysis (DEA) on various input/output combinations, focusing on sales and market value as output measures in the construction of the frontier technologies. Using these performance measures, we examine whether efficient firms perform differently from inefficient firms following standard financial analysis procedures. First, we employ performance attribution regressions, by forming portfolios based on efficiency scores and tracking the performance of the various portfolios over time. Second, we perform cross-sectional/panel regressions to determine whether firm efficiency indeed has explanatory power for the cross-section of stock returns. Our results suggest that firm efficiency plays an important role in asset pricing and that efficient firms significantly outperform inefficient firms even after controlling for known risk factors.     

Adjustment and unobserved heterogeneity in dynamic stochastic frontier models

Stochastic frontier models with autocorrelated inefficiency have been proposed in the past as a way of addressing the issue of temporal variation in firm-level efficiency scores. They are justified using an underlying model of dynamic firm behavior. In this paper we argue that these models could have radically different implications for the expected long-run efficiency scores in the presence of unobserved heterogeneity. The possibility of accounting for unobserved heterogeneity is explored. Random- and correlated random-effects dynamic stochastic frontier models are proposed and applied to a panel of US electric utilities.     

OWNERSHIP, CONTROL, FINANCIAL STRUCTURE AND THE PERFORMANCE OF FIRMS

Abstract. The notion that the separation of ownership from control may create a divergence of interests between managers and shareholders has led to a large number of studies which investigate the influence of ownership structures upon a firm's financial structure and its performance. The purpose of this paper is to review and critically evaluate the literature that empirically analyses the effects of ownership and control structures on both the financial structure and the performance of the firm. In addition, further consideration is given to the dynamic relationships between ownership, control, financing and firm performance.     

Efficiency Measurement With Unbalanced Panel Data: Evidence from Tunisian Textile,Clothing and Leather Industries

This paper is concerned with the estimation of stochastic frontier production functions with unbalanced panel data when unobservable firm efficiency levels are related to explanatory variables. We use the weighted-means Instrumental Variables method acknowledged to R. Gardner (1998) which is a modification of the Hausman-Taylor (1981) procedure adapted for unbalanced panel data. The estimation method is used to examine technical efficiency in Tunisian textile, clothing and leather (TCL) industries during the period 1983–1994. Further, we assume a Translog production frontier where input uses are expressed in efficiency units and adjusted for the age of capital and types of labor. Firm-specific time-invariant technical efficiency is obtained using Schmidt and Sickles (1984) approach. The results suggest that the Instrumental Variables method produces more accurate estimates of the unknown firm level technical efficency. Mean efficency scores resulting from the MHT method is of 66.5%.     

Demutualization,outsider ownership,and stock exchange performance: empirical evidence

We employ a balanced panel data set of 28 stock exchanges to disentangle the effects of demutualization and outsider ownership on the operative performance of stock exchanges. For this purpose we calculate in a first step individual efficiency and factor productivity values via Data Envelopment Analysis. In a second step we regress the derived values on variables that—amongst others—represent the different governance regimes of exchanges in order to examine technical efficiency and factor productivity differences between (1) mutuals, (2) demutualized but customer-owned exchanges, and (3) publicly listed and thus at least partly outsider-owned exchanges. We find evidence that demutualized exchanges exhibit higher technical efficiency than mutuals. However, they perform relatively poor as far as productivity growth is concerned. Furthermore, we find no evidence that publicly listed exchanges possess higher efficiency and productivity values than demutualized exchanges with a customer-dominated structure.      

Institutions and preferences in settings of causal complexity: foreign institutional investors and corporate restructuring practices in France

In this article, we illustrate how the interaction between institutional arrangements and the presence of different categories of firm stakeholders with specific preferences provides important insights to understand the conditions under which corporate restructuring practices are introduced. Institutions shape the range of actors' strategic options and mediate the translation of the preferences of firm stakeholders into corporate policies. Nonetheless, strategic choice remains possible since firm stakeholders constitute subgroups with different interests and incentives that influence how they operate in an institutional framework. In particular, we examine under what conditions UK/US-based institutional investors and equity-based compensation incentives are associated with the implementation of asset divestitures and employee layoffs in France. We uncover three key findings. First, the presence of hedge funds and equity-based pay influence the likelihood of French companies undertaking asset divestitures. Second, the impact of hedge funds on employee layoffs is contingent on the ownership structure of firms. Third, layoffs in France are driven by inferior performance – a result that contrasts with the American experience whereby employee layoffs are also used as a strategic mechanism to deal with institutional investors in good times. Our findings demonstrate the importance of the institutional constraints of (national level) employment protection and the moderating effects of ownership structure (firm level) on the strategic and employment policies of French companies.     

Inference in dynamic stochastic frontier models

An important issue in models of technical efficiency measurement concerns the temporal behaviour of inefficiency. Consideration of dynamic models is necessary but inference in such models is complicated. In this paper we propose a stochastic frontier model that allows for technical inefficiency effects and dynamic technical inefficiency, and use Bayesian inference procedures organized around data augmentation techniques to provide inferences. Also provided are firm‐specific efficiency measures. The new methods are applied to a panel of large US commercial banks over the period 1989–2000. Copyright © 2006 John Wiley & Sons, Ltd.     

Technical efficiency,specialization and ownership form: evidences from a pooling of Italian hospitals

We evaluate how the productive structure and level of specialization of a hospital affect technical efficiency by analyzing a six-year panel database (2000/2005) drawn from hospital discharge records and Ministry of Health data. We adopt a distance function approach, while measuring the technical efficiency level with stochastic frontier techniques. After controlling for environmental variables and hospital case-mix, inefficiency is negatively associated with specialization and positively associated with capitalization. Capitalization is typical of private structures which, on average, use resources less efficiently with respect to public and not-for-profit hospitals. Finally, by looking at scale elasticities, we find some evidence of unexploited economies of scale, leaving room for centralization.     

FIRM HETEROGENEITY,PERSISTENT AND TRANSIENT TECHNICAL INEFFICIENCY: A GENERALIZED TRUE RANDOM‐EFFECTS model

This paper considers a panel data stochastic frontier model that disentangles unobserved firm effects (firm heterogeneity) from persistent (time‐invariant/long‐term) and transient (time‐varying/short‐term) technical inefficiency. The model gives us a four‐way error component model, viz., persistent and time‐varying inefficiency, random firm effects and noise. We use Bayesian methods of inference to provide robust and efficient methods of estimating inefficiency components in this four‐way error component model. Monte Carlo results are provided to validate its performance. We also present results from an empirical application that uses a large panel of US commercial banks.

Inefficiency and heterogeneity in Turkish banking: 1990–2000

Recent studies have stressed the importance of privatization and openness to foreign competition for bank efficiency and economic growth. We study bank efficiency in Turkey, an emerging economy with great heterogeneity in bank types and ownership structures. Earlier studies of Turkish banking had three limitations: (i) excessive reliance on cost‐function frontier analyses, wherein volume of loans is a measure of banking output; (ii) pooling all banks or imposing ad hoc heterogeneity assumptions; and (iii) lack of a comprehensive panel data set for proper analysis of productivity and heterogeneity. We use an estimation–classification procedure to find likelihood‐driven classification of bank technologies in an 11‐year panel. In addition, we augment traditional cost‐frontier analysis with a labour‐efficiency analysis. We conclude that state banks are not particularly inefficient overall, but that they do utilize labour inefficiently. This partially supports recent calls for privatization. We also conclude that special finance houses (or Islamic banks) utilize the same technology as conventional domestic banks, and do so relatively efficiently. This suggests that they do not cause harm to the financial system. Finally, we conclude that foreign banks utilize a different technology from domestic ones. This suggests that one should not overstate their value to the financial sector. Copyright © 2005 John Wiley & Sons, Ltd.
