This paper examines the ability of beta and size to explain cross-sectional variation in average returns in 12 European countries. We find that average stock returns are positively related to beta and negatively related to firm size. The beta premium is in part due to the fact that high beta countries outperform low beta countries. Within countries high beta stocks outperform low beta stocks only in January, not in other months. We reject the hypothesis that differences in average returns on size- and beta-sorted portfolios can be explained by market risk and exposure to the excess return of small over large stocks (SMB). Consistent with recent US evidence, we find that after controlling for size, there is no association between average returns and exposure to SMB.  相似文献

Of prime interest to border economies is exchange rate performance and currency valuation. Commonly used tools for this task include purchasing power parity (PPP) nominal benchmarks, and inflation-adjusted trade-weighted indices. The latter have the advantage of relying on commonly available international macroeconomic data but overlook microeeonomic information that may offer additional insight to issues surrounding exchange rate policy debates. Other efforts have utilized small samples of international product price comparisons to shed light on currency valuation questions. This paper develops one such tool by repeated sampling of prices charged for identical menu items sold at restaurant franchises in El Paso, Texas, and Ciudad Juárez, Chihuahua. A battery of statistical tests indicate that the international currency value of the peso consistently differed from the exchange rate implied by the border region restaurant price ratios in 1997, 1998, and 1999.  相似文献

We study the competition between two owners of identical goods who wish to sell them to a pool of potential buyers. The sellers compete simultaneously setting reserve prices for their second price sealed bid auctions. Upon observing the set reserve prices, the buyers decide simultaneously in which auction to bid. We show that this game has (at least) one equilibrium and that all equilibria are inefficient: reserve prices are not driven to zero (cost). We also discuss where and why the parallel between optimal auction design and optimal pricing in the case of monopoly breaks down for oligopoly.  相似文献

This paper aims at analysing the impact of environmentally oriented innovative strategies on firms’ economic performance in terms of employment, turnover and labour productivity growth. We exploit a unique dataset of 773 Italian service firms with 20 or more employees, based on 1993–1995 Community Innovation Survey (CIS) II data on innovation strategies and 1995–1998 System of the Enterprise Account (SEA). Using a Gibrat‐like empirical model, our findings show a negative link between environmental motivations and growth in employment and turnover in the short term, which then associates to a not significant or even negative effect on labour productivity growth, a result which is explainable by various factors: non‐mature markets; early movers that need more time to grasp the benefits of innovative actions; weaknesses of some service branches. The effect on employment is in part compatible with the existing evidence and may be based on efficiency improvements (dematerialisation processes), which also impact on efficiency by reducing workforce numbers. The effect on turnover of environmental innovation strategy is negative, implying either a short‐medium effect, possibly balanced in the long run by net benefits in terms of higher added value, or a real negative impact, which may be contingent on the period of observation, when environmental strategies where not at the heart of strategic management policies. Neither Porter‐like effects nor virtuous circles among environmentally strategies and performance seem to be present, at least in the short run and for services firms, calling for the necessity of further analyses on medium‐ long‐term effects and performances of specific service branches. Though effects on performances could turn out positive in the long run when mature green markets and investments provide their benefits, our evidence highlights that services could still find hard times in tackling the well‐known low productivity ‘disease’ even in the environmental realm.  相似文献

Abstract

The article examines the role of the board of directors in Local Public Utilities (LPUs). It aims at verifying empirically if a correlation exists between specific characteristics of the board of directors and the adoption of innovative arrangements addressing emerging needs of users and citizens (i.e. quality). By means of applying multivariate statistical methods to a random sample of sixty Italian LPUs, this study finds the relational capital of the boards affecting the take up of quality-oriented actions by LPUs. These results support the resource-dependence theory, neglected by mainstream literature.  相似文献

This paper investigates three main questions: are affiliates of foreign multinationals more likely to exit than domestic firms? Does the exit probability of multinationals depend on its export orientation?, and Does the presence of multinationals affect the survival of other firms in the economy? Our results show that foreign plants are more likely to exit the economy, controlling for other firm and industry characteristics, only during the late 1990s, a period when the Chilean economy experience a massive slowdown. Our data also suggest that only domestic market oriented multinationals responded to this negative shock by being more “footloose”. We also find that the presence of multinationals has a positive effect on plant survival in the early 1990s. This positive effect, however, is fully captured by productivity, once controlling for TFP in our exit regressions we do not find any further impact of multinational presence on a plant's probability of exit.  相似文献

Zusammenfassung Zum “trade-off” zwischen Lohnindexierung und Intervention auf dem Devisenmarkt. - In diesem Aufsatz analysieren die Verfasser die Beziehung zwischen dem optimalen MaΒ für Lohnindexierung und dem für Wechselkursinterventionen. Die optimalen Gr?Βen für diese beiden wirtschaftspolitischen Instrumente werden mit Hilfe einer gemeinsamen Optimierung unter Berücksichtigung ihrer wechselseitigen Interdependenz ermittelt. Das bei der Untersuchung verwendete Modell wird gepr?gt durch die Charakteristika der stochastischen Schocks, die die Volkswirtschaft beeinflussen, und durch das Informations-bündel, das die Wirtschaftssubjekte annahmegem?Β besitzen. In der Analyse wird sowohl geprüft, wie der optimale Lohnindexierungsgrad mit dem gesamten Spektrum m?glicher Wechselkurssysteme zusammenh?ngt, als auch untersucht, wie das optimale AusmaΒ der Wechselkursinterventionen von dem gesamten Spektrum m?glicher Lohnindexierungsgrade abh?ngt. Eines der Hauptergebnisse ist, daΒ es keine monotone Beziehung zwischen den optimalen Werten der beiden wirtschaftspolitischen Instrumente gibt. Worin der “trade-off” zwischen ihnen genau besteht, wird in der Untersuchung im einzelnen dargelegt.
Résumé Le ?trade-off? entre l’indexation salariale et l’intervention en taux de change. — Dans cet article les auteurs analysent la relation entre les degrés optimum de l’indexation salariale et l’intervention en taux de change. Les valeurs optimum des deux instruments de politique sont obtenues par une ?optimisation? jointe considérant leur interdépendance mutuelle. Le modéle utilisé est déterminé par les caractéristiques des chocs stochastiques qui affectent l’économie et par les informations des individus. L’ analyse examine la dépendance du degré optimum de l’indexation salariale du spectre total des régimes possibles de taux de change et, vice-versa, la dépendance du degré optimum de l’intervention du spectre total des degrés possibles de l’indexation salariale. Un des résultats principaux est l’absence d’une relation monotone entre les valeurs optimum des deux instruments de politique. De plus, l’analyse détermine la nature précise du ?trade-off? entre eux.

Resumen Sobre el ?trade-off? entre la indexaci?n de salarios y la intervenci?n en el mercado de cambios. - En este trabajo los autores estudian la relaci?n entre grados óptimos de indexaci?n de salarios y de intervenci?n en el mercado de cambios. Mediante una optimizaci?n simultánea, que toma en cuenta la interdependencia de estas medidas, se obtienen valores óptimos para ambos instrumentos de politica económica. El modelo utilizado incorpora las caracterfsticas de los shocks estocásticos que afectan a la economfa y el conjunto de informaciones a disposici?n de los individuos. El análisis examina la dependencia del nivel ?ptimo de indexaci?n de salarios de todo el espectro de polfticas cambiarias posibles, como también la dependencia del nivel ?ptimo de intervenci?n en el mercado de cambios de todo el espectro de grados de indexaci?n de salarios posibles. Uno de los resultados centrales es la ausencia de una relaci?n monot?nica entre los valores óptimos de ambos instrumentos; en el análisis se détermina la naturaleza exacta del ?trade-off? que existe entre ellos.

We investigate the relation between ownership structure and firm performance in Continental Europe, using data from 675 publicly traded corporations in 11 countries. Although family‐controlled corporations exhibit larger separation between control and cash‐flow rights, our results do not support the hypothesis that family control hampers firm performance. Valuation and operating performance are significantly higher in founder‐controlled corporations and in corporations controlled by descendants who sit on the board as non‐executive directors. When a descendant takes the position of CEO, family‐controlled companies are not statistically distinguishable from non‐family firms in terms of valuation and performance.  相似文献
