Using tariffs as a measure of openness, this paper finds consistent evidence that the conditional effects of trade liberalization on inequality are correlated with relative factor endowments. Trade liberalization, measured by changes in tariff revenues, is associated with increases in inequality in countries well-endowed with highly skilled workers and capital or with workers that have very low education levels. Similar, although less robust, results are also obtained when decile data are used instead of the usual Gini coefficients. Taken together, the results are strongly supportive of the factor-proportions theory of trade and suggest that trade liberalization in poor countries where the share of the labor force with little education is high raises inequality. Simulation results also suggest that relatively small changes in inequality as measured by aggregate measures of inequality, like the Gini coefficient, are magnified when estimates are carried out using decile data. 相似文献

This paper analyzes the relationship between income inequality and inequality of opportunities for income acquisition in nine developed countries during the 1990s. Equality of opportunity is defined as the situation where income distributions conditional on social origin cannot be ranked according to stochastic dominance criteria. We measure social origin by parental education and occupation and use the database built by Roemer et al. (2003 ). Stochastic dominance is assessed using nonparametric statistical tests. Our results indicate strong disparities in the degree of equality of opportunity across countries and a strong correlation between inequality of outcomes and inequality of opportunity. The U.S. and Italy show up as the most unequal countries in terms of both outcome and opportunity. At the opposite extreme, income distributions conditional on social origin are almost the same in Scandinavian countries even before any redistributive policy. We complement the ordinal comparison by resorting to an original scalar “Gini” index of opportunities, which can be decomposed into a risk and a return component. In our sample, inequality of opportunity is mostly driven by differences in mean income conditional on social origin, and differences in risk compensate the return element in most countries. 相似文献

Recent research has shown that exposure to songs with prosocial lyrics was associated with prosocial behavior and accessibility of prosocial thoughts. However theses studies were performed in a laboratory setting where participants were instructed to listening songs alone in a room. So the effect of prosocial songs in a natural setting, with several people in a room and with various ambient noises still remained in question. An experiment was carried out in a restaurant in order to test if listening or not, prosocial songs by patrons, was associated with variation in their tipping behavior. Results showed that prosocial songs were associated with a significant increase in tipping behavior. 相似文献

We propose a model of two‐tier competition between vertically integrated firms and unintegrated downstream firms. We show that, even when integrated firms compete in prices to offer a homogeneous input, the Bertrand logic may collapse, and the input may be priced above marginal cost in equilibrium. These partial foreclosure equilibria are more likely to exist when downstream competition is fierce or when unintegrated downstream competitors are relatively inefficient. We discuss the impact of several regulatory tools on the competitiveness of the wholesale market. 相似文献

The best predictor of current investment at the firm level is lagged investment. This lagged-investment effect is empirically more important than the cash-flow and Q effects combined. We show that the specification of investment adjustment costs proposed by Christiano et al. (2005) predicts the presence of a lagged-investment effect and that a generalized version of their model is consistent with the behavior of firm-level data from Compustat. 相似文献

Abstract The following problem is considered: for which p ∈ (0, 1) and completely monotone functions g is g/[p+(1-p)g] completely monotone? This problem is shown to be equivalent to the inverse problem for thinned renewal processes. Some applications to gamma renewal processes are also discussed. 相似文献

The most important families of R&D project evaluation and selection methodologies and associated techniques are briefly reviewed. For each family, generally one or two methods were chosen to be analysed from the point of view of the integration with the strategy. But, first some definitions and some aspects of the new strategic role of the evaluation and selection of R&D projects, which were in mind during the interviews, are presented.
Finally, some empirical results of the use of these methodologies in France and Japan are presented. The strong and weak points of the most prevalent methods are described as they are considered by the users. 相似文献

We analyze the effect of investor attention on stock prices around Chapter 11 bankruptcy filings. We measure investor attention as abnormal search volume from Google, and find that attention‐grabbing companies have more negative abnormal stock returns in the days before and during bankruptcy filings and more positive abnormal returns immediately thereafter. That is, for companies receiving high attention, investors overreact to a bankruptcy filing; for companies receiving low attention, they underreact. This pattern is more pronounced for companies with low institutional ownership and holds after controlling for standard predictors of stock performance during bankruptcy. 相似文献

We examine the interaction between commodity taxes and parallel imports in a two-country model with imperfect competition. While governments determine non-cooperatively their commodity tax rate, the volume of parallel imports is determined endogenously by the retailing sector. We compare the positive and normative implications of having commodity taxes based on destination or origin principle. We show that, as the volume of parallel imports increases, non-cooperative origin taxes converge, while destination taxes diverge. Moreover, origin taxes are more similar and lead to higher aggregate welfare levels than destination taxes. 相似文献
