Is There a Glass Ceiling over Europe? Exploring the Gender Pay Gap across the Wages Distribution Using harmonised data from the European Union Household Panel, we analyse gender pay gaps by sector across the wages distribution for ten countries. We find that the mean gender pay gap in the raw data typically hides large variations in the gap across the wages distribution. We use quantile regress...

Substantial racial disparities continue to persist in the prevalence of preterm births and lowbirth-weight births. Health policy aimed at reducing these disparities could be better targeted if the differences in birth outcomes are better understood. This study decomposes these racial disparities in birth outcomes to determine the extent to which the disparities are driven by differences in meas...

(2007) demonstrated. in addition to four traditional wedges, we introduce additional trade wedge. we then evaluate the contribution of these wedges to the fluctuations in iran during last three years. because of international sanction, trading cost increases, and firms have difficulty to...

The paper considers governments' public procurement decision as a way of influencing industry structure. In a federation in which capital is mobile and capital taxation is harmonized, a home bias in public procurement can potentially be explained as an effort to increase the capital intensity of local production and to attract taxable capital. As a result, governments may prefer domestic firms ...

Lotteries are introduced into Cavalcanti and Erosa (2008) [2], a version of Trejos and Wright (1995) [4] with aggregate shocks. Lotteries improve welfare and eliminate the two notable features of the optimum with deterministic trades: over-production and history-dependence. Moreover, the optimum can be supported by buyer take-it-or-leave-it offers. © 2011 Elsevier Inc. All rights reserved. JEL ...

The Income Gap Between Natives and Second Generation Immigrants in Sweden: Is Skill the Explanation?

Since, in principle, every male Swedish citizen takes the test when turning 18, we are able to b...

Using administrative data from the state of Georgia, this paper finds that, on average, across all firms, employing undocumented workers reduces a firm’s hazard of exit by 19 percent. The advantage to firms from employing undocumented workers increases as more firms in the industry do so, decreases with the skill level of the firm’s workers, increases with the breadth of a firm’s market, and in...

This paper provides a dynamic optimization model of durable good inventories to study the interactions between investment demand and production of capital goods. There are three major findings: First, capital suppliers’ inventory behavior makes investment demand more volatile in equilibrium; Second, equilibrium price of capital is characterized by downward stickiness; Third, the responses of th...
