We analyse congestion pricing in a road and rail network, where the two modes are imperfect substitutes. On the road there is bottleneck congestion; in each train there is crowding congestion. We model two dimensions of preference heterogeneity; these two dimensions have opposite effects on the welfare impact of congestion pricing and lead to different distributional effects. The distributional...

Migration, Transfers and Child Labor We examine agricultural child labor in the context of emigration, transfers, and the ability to hire outside labor. We start by developing a theoretical background based on Basu and Van, (1998), Basu, (1999) and Epstein and Kahana (2008) and show how hiring labor from outside the household and transfers to the household might induce a reduction in children’s...

This paper focuses on a congestion externality in the labor market which is caused by non sequential search. A model is presented in which unemployment is caused by selection delays of the employers It is shown that the individual probability to get a job offer is increasing in the number of applications but that the aggregate hiring rate is decreasing in the average amount of applications per ...

We introduce ill will among the players of the classic two-sided assignment game of Shapley and Shubik, by letting each player’s utility be negatively correlated with the payoff of all players in his group. The new game is very complex, but under a certain assumption of bounded rationality we derive a straightforward notion of stable outcomes as certain conjectural equilibria. We prove that sev...

In this work Public Goods are analyzed from the point of view their definition as «non-excludable» and «non-rivalry» in order to show contradictions it entails. Also we propose Political a proper name define those goods provided by state apart basic ones (security justice) therefore how these result political pressure arbitrary decisions bureaucrats (which is studied works James Buchanan on Dem...

Epigenetic changes in response to external stimuli are fast emerging as common underlying causes for the pre-disposition to adult disease. Prenatal androgenization is one such model that results in reproductive and metabolic features that are present in conditions such as polycystic ovary syndrome (PCOS). We examined the effect of prenatal androgens on liver function and metabolism of adult she...

The front cover image illustrates the successful production of “heavy” deuterated linoleic acid. Deuterium was installed at beginning synthesis via hydrothermal deuteration readily available saturated fatty acids. acids were stitched together to ultimately afford requisite cis,cis-skipped diene Deuterated acid is required for labelled biologically relevant linoleoyl lipids, whereby facilitates ...
