We study the different levels of corporate social responsibility (CSR) disclosures of the largest European firms. We find that firms are more predisposed to disclose more CSR information in countries with better investor protection, higher levels of democracy, more effective government services, higher quality regulations, more press freedom, and a lower commitment to environmental policies. Our analysis of the association of different levels of CSR disclosure with share prices indicates that a high level of CSR disclosure is associated with higher share prices, whereas a low level of CSR disclosure in sensitive industries is associated with lower share prices (compared to no disclosure). These results are also present when we analyse changes in CSR disclosure and are robust to the inclusion of an accounting quality measure in our model. The overall effect of the association of higher levels of CSR disclosure with higher share prices is stronger in countries with more democracy, more government effectiveness, better regulatory quality, and more press freedom. Therefore, market participants find CSR disclosures more informative in countries where investors are in a better position to voice their concerns and where there is better regulation and more effective government implementation of regulations.  相似文献

We analyze the roles of inward foreign direct investment (FDI) and imports of capital goods as the main drivers of technology diffusion and productivity improvement in a sample of twenty-eight developing economies for the period 1999-2009. We examine changes in the sectoral composition of FDI as well as those local conditions that may facilitate technology adoption. Our results, obtained by the system generalized method of moments estimation method, suggest that the change of FDI from manufacturing to services is productivity enhancing. We also find that those countries with stronger institutions and better social and human development enjoy larger efficiency gains.  相似文献

Appeals to public participation and, more generally, to a wider involvement of civic networks in the management of environmental conflicts are becoming more common after the difficulties that both the Market and the State appear to have in regulating these conflicts. The concern of this paper is with how central elements in civic society, such as interpersonal trust and community-building mechanisms, are influenced by environmental catastrophes. The case of the toxic spill disaster in Doñana, Spain, is presented in order to examine whether this accident had any effect on interpersonal trust and the mobilization of civic networks in the area. From the analysis, it can be concluded that involvement of civic networks in the management of these situations depends on the magnitude (real or perceived) of the disaster but also on the performance of public institutions regarding the event.  相似文献

The literature on equity markets documents the existence of mean reversion and momentum phenomena. Researchers in foreign exchange markets find that foreign exchange rates also display behaviors akin to momentum and mean reversion. This paper implements a trading strategy combining mean reversion and momentum in foreign exchange markets. The strategy was originally designed for equity markets, but it also generates abnormal returns when applied to uncovered interest parity deviations for five countries. I find that the pattern for the positions thus created in the foreign exchange markets is qualitatively similar to that found in the equity markets. Quantitatively, this strategy performs better in foreign exchange markets than in equity markets. Also, it outperforms traditional foreign exchange trading strategies, such as carry trades and moving average rules.  相似文献

The main purpose of this paper is to compare the White (1980) heteroskedasticity-consistent (HC) covariance matrix estimator with alternative estimators. Many regression packages compute the White (1980) heteroskedasticity-consistent (HC) covariance matrix estimator. The common procedure in Accounting and Finance research to deal with the heteroskedasticity problem is based on this estimator, despite its worse finite-samples properties when compared with other consistent estimators. In this paper we compare several HC covariance matrix estimators based on a sample of 3706 European listed companies from Austria, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Portugal, Spain, Sweden and the United Kingdom. We conclude that HC standard errors increase when finite-samples more appropriate estimators are considered and in the most part of countries the Ohlson (1995) model coefficients estimates became statistically insignificant. This can be explained by the high leverage points in the design matrix. To the best of our knowledge it is the first time that these alternative estimators are compared with the one of White (1980) in accounting research.  相似文献

This paper examines the prominence of non-GAAP financial measures in press releases, testing whether managers emphasize these adjusted performance measures relative to GAAP numbers in four different settings where their disclosure helps managers reach strategic earnings benchmarks on a pro forma basis when they would otherwise fall short using GAAP numbers. Moreover, this research investigates the information content of disclosures reconciling non-GAAP to GAAP earnings (and other financial statements). The data is hand collected from quarterly earnings press releases of a sample of S&P 500 firms during the 2001–2003 period. In this particular sample, the disclosure of non-GAAP financial measures is frequent. The results suggest that managers strategically give more prominence to non-GAAP measures than to GAAP figures when the GAAP earnings number falls short of a benchmark but the non-GAAP earnings number does not. This disclosure strategy may influence the perception of the firm's financial results. Furthermore, the results suggest that both the reconciliation and the non-GAAP income statement contain information useful for users.  相似文献

Using dry-cured ham as an anchor product, consumers’ preferences for EU Quality Certification schemes, region of origin and price have been investigated with conjoint analysis. In order to achieve this aim, a mixed rank-ordered logit which allows for the investigation of heterogeneous preferences and their sources has been estimated. In particular, we have analysed to what extent consumers’ socio-demographic traits affect their price-sensitiveness and whether consumers’ sensory (hedonic) valuations and attitudes towards ham with a Protected Designation of Origin (PDO) affect the preferences for specific attributes. Results show that consumers with a low-medium age and income are more price sensitive. Consumers more inclined sensorially towards the regional specialty (with or without PDO) are more likely to purchase this product, and consumers with a more favourable attitude towards PDO ham are also more prone to purchase cured ham with quality certification. Findings also suggest that although the PDO scheme attracts a segment of consumers, the origin by itself is still a more powerful signal of quality, and more specifically the region of origin.  相似文献

Most patent licensing agreements observed empirically include either per-unit or ad valorem royalties. The theoretical literature generally focuses on per-unit royalties. We provide a simple justification for the presence of ad valorem royalties in licensing contracts.  相似文献

The marketing literature has shown how certain attributes of the store are key for grocery retailers to differentiate themselves in the final markets. From this preliminary consideration the present work proposes a step forward by ascertaining the main factors that underlie the attributes of the store which have already been identified in the literature. All of this is taken into account with the object to examine which of these factors presents a greater influence on customer satisfaction. To test the proposed analysis, a sample of 358 Spanish customers that had carried out their purchase in different types of grocery stores (in particular, hypermarkets and supermarkets) has been analyzed considering a key variable of retail patronage behavior: the store format in which the purchase had been carried out. This study has enabled us to obtain interesting conclusions about the variables that have the most influence on customer satisfaction, providing useful managerial recommendations for decision-making in grocery retailing.  相似文献

This article studies the behavior of input cost shares in an environment where labor is costly to adjust, materials can be adjusted at no cost and capital is fixed. A model relating cost shares with relative prices and adjustment costs is proposed, allowing joint estimation of the elasticity of substitution and the adjustment cost function, which is an unknown function of the capacity utilization. Based on a panel of more than 700 manufacturing firms, we find evidence of strong input share variations according to the degree of capacity utilization. The estimated shapes of adjustment costs curves of labor are in agreement with our theoretical model, and we obtain sensible elasticities of substitution estimates. Based on such estimates, we find evidence of a negative (positive) bias in downturns (recoveries) in conventional productivity growth measures.  相似文献
