Programs to reduce traffic congestion and air pollution by restricting use of motor vehicles on working days have generally not met with success, given existing studies of such programs. We conduct the first study of Quito, Ecuador's four‐year‐old Pico y Placa program and find that it has reduced ambient concentrations of carbon monoxide (CO), a pollutant primarily emitted by vehicles, by 9% to 11% during peak traffic hours. Given that ambient concentrations of CO generally track the spatial and temporal distributions of traffic, these reductions in pollution suggest similar reductions in vehicle flows. We find no significant evidence that traffic has shifted to other times of the day or week, or to other locations. 相似文献

This paper investigates the relationship among auditor quality, International Financial Reporting Standard (IFRS) adoption and stock price crash risk. Using 657 unique listed companies spanning 2002–2014 in Korea, this study finds that stock price crash risk decreases, especially for firms using Big 4 auditors, after IFRS adoption in Korea. Stock price crash risk decreases for a firm included in Big 4 auditors, while it does not increase for a firm excluded from Big 4 auditors after IFRS adoption. Finally, this study finds that Big 4 auditor decreases stock price crash risk only when the firm size is above-median. 相似文献

The number of strategic alliances for R&D activities in the biotechnology industry is sharply increasing. Some studies show that each alliance partner type has different alliance motives, resources and capabilities, organizational structures and cultures, and degrees of competition with partners, which can lead to different performances of strategic alliances. In this regard, this study conducts an empirical analysis of the different impact of each type of alliance partner on technological innovation performance and finds the moderating effect of absorptive capacity and potential competition by categorizing strategic alliances for R&D activities in the biotechnology industry into three types: vertical-downstream alliances, vertical-upstream alliances, and horizontal alliances. This study analyzed 206 Korean biotechnology firms and their strategic alliances for a total of 292 R&D activities. The results of the analysis showed that vertical alliances have a positive impact on technological innovation performance, while horizontal alliances have an inverted U-shaped relationship with technological innovation performance caused by the effect of competition. Additionally, it was confirmed that the R&D intensity of biotechnology firms has a moderating effect of increasing the impact of vertical-upstream alliances on technological innovation performance. 相似文献

The world’s nations often produce commodities for which they have no apparent comparative advantage, and do so with techniques
that are not particularly efficient by world standards. These inefficiencies may arise from various forms of trade and domestic
distortions, as described in Chau et al., Int Econ Rev 44:1079–1095, (2003). We estimate these distortions for 33 countries of the world using a newly compiled data set. We find that domestic distortions
tend to be slightly more important than trade distortions. For the average country, revenues in the agricultural sector would
be 26% higher if domestic distortions were eliminated, but 21% higher if trade distortions were eliminated. Our measures of
trade and domestic distortions across countries provide a complement to measures of protectionism such as producer subsidy
equivalents. 相似文献

This paper presents a model of rent competition in a mixed economic system in which wealth maximizing interest group coalitions share wealth according to their relative political power. The model solves for optimal lobbying expenditures of a producer group, a consumer group, and individual firms. The existence of monopolistic rent is not presupposed. Instead, the equilibrium market price, output, and market shares of firms are determined endogenously. As a result, the distribution of rent depends upon the relative political power of each interest group coalition and total lobbying expenditure decreases as the asymmetry in marginal political power among interest group coalitions increases. 相似文献

ABSTRACTOur model relates the variability of stock returns to the variability of consumption velocity and shows that real stock returns tend to co-vary negatively with expected inflation in a period (or regime) of low and stable inflation and to co-vary positively with expected inflation in a period (or regime) of high and volatile inflation. Long-run real stock returns are shown to be positively related to expected inflation. Our empirical results for 20 countries provide consistent support for our propositions, indicating that the standard deviation of the annual inflation rate roughly equal to 10% is the dividing line between negative and positive return-inflation relations. 相似文献
