This paper analyzes the determination of the optimal environmental regulatory policy under imperfect competition when the firms differ in their polluting technologies and degree of honesty. We show that more honesty does not necessarily imply lower social losses. The effect of honesty in social welfare depends not only on the degree of honesty measured by the proportion of honest firms and their particular cost features but also on the industry structure.  相似文献

Given the intense competition experienced in the sector, retailers have been designing strategies to create an environment conducive to consumer satisfaction and purchase, particularly in supermarkets and hypermarkets. This paper develops a conceptualization of customer satisfaction based on field data collected in a specialty store, focusing on the relative importance of the environmental factors on satisfaction. The results show that the most important environmental determinant of customer satisfaction is the variety of products. The help from employees, lighting, layout and design also stand out from the set of stimuli considered.  相似文献

This article explores the drivers of regional stock market integration with a focus on the agribusiness sector across relevant regional trade blocs around the world. We implement panel cointegration models to analyze the stock indices of agribusiness firms in the Southern Common Market (MERCOSUR), European Union (EU), Asia‐Pacific Economic Cooperation (APEC), and North American Free Trade Agreement (NAFTA). Based on the literature on market integration and stock return pricing, we identify nine possible determinants of stock market integration, which we separate into three categories: individual market performance, macroeconomic conditions, and agricultural trade. In our analysis, we account for agriculture‐specific factors to control for possible structural shifts in financial markets regimes by including the two main commodity price bubbles during last 20 years. Our results show that most of the variables included in our categories have been important factors in promoting regional stock market integration. Moreover, integration among regional stock markets was strengthened by the implementation of trade agreements. This effect is stronger in trade blocs with fewer members, such as NAFTA and MERCOSUR, compared with larger and more heterogeneous blocs, such as the EU and APEC.  相似文献

As documented in the literature, the effects of firm size, financial leverage, and R&D expenditures on firm earnings are inclusive. Our hypothesis is that the inconsistent empirical results of such effects may be driven by the regression models implemented in data analysis. Using the quantile regression (QR) approach developed by Koenker and Basset (1978), this study analyses S&P 500 firms from 1996 to 2005. We find that the effects of firm size, financial leverage and R&D expenditures on firm earnings differ considerably across earnings quantiles. Comparing the results from the QR approach with those from the ordinary least squares (OLS) and least absolute deviation (LAD) methods, this study further explains the puzzling relationship between firm size, financial leverage, R&D expenditures and firm earnings.  相似文献

In this paper we examine the impact of foreign bank penetration on the competitive structure of domestic banking sectors in host emerging economies. We focus our analysis on Asia and Latin America during the period 1997-2008. Using bank-level panel data to identify foreign banks and to estimate measures of banking competition, we are able to provide robust empirical evidence that an increase in foreign bank penetration enhances competition in these host countries’ banking sectors. We find that this positive foreign bank penetration and banking competition link is associated with a spillover effect from foreign banks to their domestic counterparts. This spillover effect becomes stronger when more efficient and less risky foreign banks enter into less concentrated host country markets. We also find that the spillover effect is greater when foreign banks enter in the form of ‘de novo penetration’ than through mergers or acquisitions of domestic banks (‘M&A penetration’).  相似文献

This paper explores a wide range of corporate restructurings, all available deals from wire services, in the banking and insurance sectors that led to bancassurance ventures. An event study methodology is employed to calculate excess returns on and around the deals’ announcement date. Using both univariate and multivariate analysis the paper finds bank driven mergers, deal's size and regional categorization all triggering positive and significant market reactions. Unlike the univariate framework, multivariate analysis shows that geographic focus and language are not significant factors. The results also indicate that markets are indifferent with respect to bank withdrawals from the bank‐insurance operations. Finally, Canadian, U.S. and European bank‐insurance deals produce positive results, while Australasian bidders offer statistically insignificant equity returns.  相似文献

This article analyses 336 German venture capital transactions from 1990 to 2005 and seeks to determine why selected financial securities differ across deals. We find that a broad array of financial instruments is used, covering straight equity, mezzanine and debt‐like securities. Based on the chosen financial securities’ upside potential and downside protection characteristics, we provide an explanation for the differing use of these securities. Our results show that investors’ deal experience, adverse selection risks and economic prospects in the public equity market influence the selection of financial securities.  相似文献

This paper reports the findings of a longitudinal comparative case study of three National Health Service (NHS) hospital Trusts in England, investigating the perceptions of clinical, managerial and accounting professionals towards changing cost accounting and performance measurement practices. It incorporates both qualitative and quantitative data analysis, and is based on a contextualist understanding of change management, utilising the content‐process‐context approach (Pettigrew and Lapsley, 1994) to investigate the influence of receptive versus non‐receptive contexts on change. The analysis reveals limited success in improving performance measurement practices (the content of change) in Trusts. Nevertheless the specific context within which change was operationalised was found to be very important, with central mangers playing a key role in influencing change. The process of change indicated slow shifts in clinical‐accountant‐managerial relations, partly driven by changes in financial flows within the organisations.  相似文献

We analyze the statistical properties of three price discovery measures: The variance ratio, the weighted price contribution (WPC), and the R2 of unbiasedness regressions. We find that, if the price process is a driftless martingale, only the WPC is an unbiased estimator for the return variance explained during a time interval. For autocorrelated processes with a drift, only the R2 of the unbiasedness regression is consistent, but it is biased for small samples.  相似文献

This study investigates the signalling role and rectification effectiveness of an audit partner disciplinary system. The signalling role refers to whether sanctions reflect the poor audit quality of disciplined audit partners, and rectification effectiveness addresses whether disciplinary actions enhance subsequent audit quality. The sample consists of Taiwanese listed companies, in the period 2000 to 2006, where the identities of audit partners who sign audit reports and who are sanctioned are accessible. Empirical results indicate that in the pre‐sanction period, the probability of financial restatements by clients of disciplined audit partners is significantly higher than that of non‐disciplined audit partners. The more severe or frequent the sanctions, the higher the likelihood of financial restatements in the pre‐sanction period. These findings imply that audit partner disciplinary actions can serve as a signal of lower audit quality provided by those partners. The rectification effectiveness of disciplinary actions is examined from two perspectives: (1) the effects on subsequent improvements of audit quality of disciplined audit partners; and (2) audit quality enhancement of successor non‐disciplined audit partners who accept clients from disciplined audit partners. Empirical results show a lower probability of restating financial statements audited by disciplined audit partners after sanctions. We also find a lower likelihood of restating financial statements audited by successor non‐disciplined audit partners in the post‐sanction period. Both findings support our conclusion that audit partner sanctions improve audit quality. Overall, audit partner disciplinary actions can signal lower quality audit partners and are effective in enhancing audit quality.  相似文献
