This assumption allows us to make a priori estimates of weak solutions satisfying the entropy inequality ∂tu+ divQ(u) ≤ 0, such that u(·, t)− ū is square integrable. The purpose of this paper is to study viscous extensions of (1) that are compatible with the entropy, in the sense that there is an entropy inequality for classical solutions of the extended system. In our weakest setting, such an ...

We study the nature of regional inequality in Colombia over the past 200 years. The main empirical fact is that regional inequality has been highly persistent despite the large changes that have taken place and the modernization of the society. We show that regional inequality is highly correlated with significant within-country differences in economic and political institutions, which are them...

This thesis examines salary structure types (hierarchical or compressed) as predictors of team performance in the National Hockey League (NHL). Additionally, an analysis of goalie statistics is completed in order to determine what, if any, performance measures relate to salary. Data in this research were collected from the 2005-06 season up to the 2010-11 season. Salary inequality/equality (Gin...

This paper is concerned with the asymptotic behavior solutions of stochastic differential equations dyt = dωt − ∇V (yt)dt, y0 = 0. When d = 1 and V reflects media characterized by an infinite number of spatial scales V (x) = ∞ k=0 Uk(x/Rk), where Uk are smooth functions of period 1, Uk(0) = 0, and Rk grows exponentially fast with k, we can show that yt has an anomalous slow behavior and obtain ...

Sufficient conditions for robust stability using generalized stability multipliers are presented for systems with sectorand norm-bounded, block-structured real uncertainty. Two parametrizations of the multiplier are considered and the robustness criteria are written as linear matrix inequalities. Upper bounds for the peak structured singular value over frequency, which eliminate frequency gridd...

Capital accumulation can modify the relative productivity between skilled and unskilled workers, leading to changes in the wage structure. In particular, if capital goods are relatively more complementary to skilled workers, a positive correlation between investment in physical capital and the wage premium would be expected. In this paper, we present evidence for this hypothesis by taking advan...

This paper examines the link between access to credit and child labor at a cross-country level. Even though access to credit is central to child labor theoretically, there has been little work done to assess its importance empirically. We measure child labor as a country aggregate, and credit constraints are proxied by the level of financial development. These two variables display a strong neg...

Using a linked employer-employee data set of the German manufacturing sector, this paper analyses the role of exporting establishments in explaining rising wage dispersion. Over the period of analysis (1996–2007), the raw wage diff erential between exporters and domestic establishments increased substantially, which can only partly be attributed to corresponding changes in human capital endowme...
