This paper contributes to the literature on integovernmental competition in two ways. First, the institutional setting within which public services are delivered is analyzed with respect to the impact on the quality of services provided. Previous studies have measured competition only in terms of governmental structure, ignoring the issue of service quality and the potential for differentiating local governmental jurisdictions along quality dimensions. Second, the outcome of competition is defined in terms of service quality. Previous studies generally have measured the outcome of competition by examining the fiscal effects of fragmentation and accountability through service costs or tax revenue impacts. School districts were used to empirically test quality competition. Student academic performance was modeled as a function of control variables and the degree of competition from neighboring school districts. Academic performance in public schools was positively associated with the performance of neighboring districts, although the effect was small. These findings, however, suggest that strategies to strengthen interjurisdictional competition may be useful in enhancing public service quality.  相似文献

Even though electrical companies attain a top ranking in the publication of CSR reports, they are often accused of 'green‐washing' due to their bad environmental reputation. The current economic crisis is testing their real CSR commitment more than ever, especially when this goes beyond its economic consequences. Based on a worldwide sample of electrical companies, we are going to study why companies are being socially responsible. We wish to know if it is due to the impact on the firms' performance or whether there are other motives (legitimation, improving their reputation) that lead companies to carry out these practices. We will also consider if it changes across the kind of CSR action considered. The results show that there is an economic justification beyond the socially responsible behaviour of the electrical companies. Additionally, most kinds of CSR action (community, diversity, corporate governance, product responsibility) are also carried out looking for economic rewards. However, the CSR actions oriented to the environment are mainly motivated by their need to improve their image and reverse their negative impact.

This article presents a new three-sector general-equilibrium model for tax incidence analysis. The model differs from the usual two-sector model not only in the addition of an extra sector but also in abandoning the classical tradition of specifying with capital and labor arguments. The property tax in the model is specified as a partial tax applying to real — but not to personal — property used in the production of housing services and other goods.The model is quantified by selecting numerical values for its parameters in order to estimate percentage changes in the endogenous variables caused by the introduction of an exogenous property tax. The major effect of the tax is to make real property relatively more expensive and to cause less real property to be produced.  相似文献

The betting market for the NHL is investigated using actual betting percentages on favorites and underdogs from real sportsbooks. Sportsbooks do not appear to attempt to price to balance the book as betting percentages are not proportional to set odds. As in the NFL and NBA, bettors are shown to have a strong preference for favorites and road favorites in particular. Simple strategies of betting against significant imbalances toward the favorite are shown to generate positive returns. Although not pricing to balance the book, sportsbooks do not appear to price to exploit known bettor biases in all cases. Clear bettor behavioral biases for road favorites are not priced into the odds as the prices set in these cases appear to be a forecast of game outcomes. Pricing as a forecast may ensure long-run viability for the sportsbook as it discourages entry into this market by informed traders and still allows the sportsbook to capture its commission on losing bets over time.  相似文献

This research adds to the growing literature on what draws consumers to ethical brands. Findings from three studies demonstrate that guilt motivates consumers to connect with ethical brands, especially those consumers with high levels of moral identity importance (MII). Specifically, Study 1 finds that consumers report stronger self‐brand connections (SBCs) with an ethical brand when they feel guilty (vs. control). Study 2 finds that guilt particularly motivates consumers with high MII to report stronger SBCs with an ethical (vs. unethical) brand. In turn, these strong connections lead to increased intentions to purchase the ethical brand. Finally, Study 3 finds evidence for the proposed motivation‐based process explanation by showing that high MII consumers’ propensity to connect with ethical brands when feeling guilty (vs. control) is attenuated when these consumers are first given the opportunity to donate to a charitable cause to alleviate their guilt. Overall, the findings suggest that ethical brands can foster strong connections with and elicit higher purchase intentions from consumers seeking ways to alleviate their guilt.  相似文献

This paper studies the exchange rate dynamics of the Mozambique metical with respect to the US dollar and the South African rand. However, instead of using standard I(0)/I(1) techniques, we use long memory and fractionally integrated and co‐integrated models. Our results indicate that the two exchange rates are highly persistent, with orders of integration equal to or above 1. They also seem to be co‐integrated, with an order of integration close to albeit above 0 but with an AR coefficient very close to 1. Thus, although the two series seem to be fractionally co‐integrated, shocks in the long‐run relationship between the two variables are persistent and take a long time to disappear.  相似文献
