We investigate endogenous timing in a mixed duopoly in a differentiated product market. We find that private leadership is better than public leadership from a social welfare perspective if the private firm is domestic, regardless of the degree of product differentiation. Nevertheless, the public leadership equilibrium is risk-dominant, and it is thus robust if the degree of product differentiation is high. We also find that regardless of the degree of product differentiation, the public leadership equilibrium is risk-dominant if the private firm is foreign. These results may explain the recent revival of public financial institutions in Japan. 相似文献

Scholars of race tend to measure racial inequality in either absolute or relative terms. How much Blacks have advanced from their historical antebellum status is an absolute measure. How the status of Blacks compares with that of Whites is a relative measure. A more revealing measure might be how much racial equality will be strategically necessary to avoid a major politico-economic crisis like the ones that occurred during the civil war and the 1960s. Though it is easier to measure absolute or relative equality, measures of strategic equality yeild more important information. Using the Current Population Survey, General Social Survey, Center for Education Statistics, Multi-City Study of Urban Inequality, and Census Bureau estimates, I find that, strategically, America is actually declining in racial equality, not advancing. 相似文献

Voter participation rates vary widely across the 50 states. We seek to identify a source of this interstate variation, focusing upon the 2000, 2004, 2008, and 2012 general elections. Of note is that the latter two general elections featured a minority (i.e., African-American) nominee for president from one of the major political parties. Within the context of the rational voter model, we hypothesize that the presence of a minority candidate atop the ticket will boost minorities’ expected net benefits from voting, with the result that minority voter participation will be higher. Based on cross-sectional fixed-effects estimations, we find that states’ voter participation rates were unaffected by the percent of the population that was either African-American or Hispanic for the 2000 and 2004 election cycles, while states’ voter participation rates were positively related to the percent of the population that was either African-American or Hispanic for the 2008 and 2012 election cycles. 相似文献

Optimal Exchange-Rate Policy in a Model of Local-Currency Pricing with Vertical Production and Trade
In this paper, we examine optimal exchange-rate flexibility in a model of local-currency pricing with vertical production and trade. Following a large body of empirical evidence, we assume that final-goods prices are sticky, but intermediate-goods prices are flexible. We find that, unlike what is found in the literature, optimal nominal exchange rate is flexible under local-currency pricing. The key element in deriving our conclusion is the difference in expenditure shares between home and foreign households. The conclusion holds even if the degrees of home bias in production are identical between home and foreign final-goods producers, which contrasts with the findings in the literature. 相似文献

This paper investigates the effect of nearby nature substitute sites on preferences for nature restoration. Contrary to prior studies, we use a respondent-centric approach to control for substitute sites. We assess each respondent-specific spatial context by computing densities of nature substitute sites within various ranges from each respondent’s home. This approach considers the use and non-use values of nature together. Data from three similar discrete choice experiments carried out in Flanders (Belgium) are compared. Different spatial discounting factors are tested to explore how the substitution effect behaves with regard to distance. Latent class analyses are performed to account for preference heterogeneity among respondents. We observe divergent behaviours across groups of respondents. The “distance-to-substitutes” affects how respondents gauge substitute sites. We find a significant influence of the squared average buffer distance but this effect varies in sign across case studies and classes of respondents. Our results demonstrate that individual-specific GIS data can significantly improve the representation of the spatial context and the transferability of value functions. However, the roles played by preference heterogeneity and nature perception on respondents’ capacity to value nature still deserves further attention in future research. 相似文献

This study examines whether there was a Malthusian equilibrium mechanism in Sweden in the pre-industrial period. A unique data set on harvests, deaths, marriages and births going back to 1630 is used to calculate cumulative elasticities of vital rates with respect to harvest. While earlier studies have mostly focused on the impact of real wage, this study uses the calorie content of per capita harvests as an indicator of living standards. It finds that there indeed was a response of vital rates to harvest fluctuations, but there were important structural breaks. While positive checks attenuated after 1720, preventive checks were strengthened. After 1870 preventive checks disappeared, and possibly also positive checks. The results are robust to different models and trend specifications, with one crucial difference: while the distributed lag model shows that positive checks were significant up to 1920, the SVAR model shows that positive checks disappeared after 1870. 相似文献

How young firms achieve growth: reconciling the roles of growth motivation and innovative activities
This special issue focuses on entrepreneurship, innovation and enterprise dynamics, as these key components of any prospering economy are at the heart of the current policy discussion. It gathers the latest national and comparative cross-country evidence about: new business venture formation and the role of framework conditions in fostering entrepreneurial activities; the determinants and outcomes of firms’ innovative activities and, more generally, of business and innovation dynamics; and the determinants and patterns of post-entry firm growth performance. The contributions synthesised in this introductory piece all rely on sound micro-level data and robust econometrics and propose novel findings that are relevant for policy making. Among them, that risk aversion encourages individuals to invest in balanced skill profiles, making them more likely to become entrepreneurs; and that while micro firms may grow when they are young, they are less likely to do so when old. 相似文献
