A large body of empirical research indicates that countries with relatively low policy-induced trade barriers tend to enjoy relatively rapid growth, ceteris paribus. In contrast, alternative theoretical models suggest that the relationship between trade barriers and growth may be contingent on the level of income. Employing a direct trade-barrier measure —(More)
In the context of a simple asset-pricing environment, we study the ability of self-control preferences to account for the stock-price volatility, risk-free-rate and equity-premium puzzles. Using a full-information estimation procedure, we estimate the presence of a quantitatively small selfcontrol e¤ect in the data. Moreover, with results obtained using(More)
Theoretical studies have shown that under unorthodox assumptions on preferences and production technologies, collateral constraints can act as a powerful ampliÞcation and propagation mechanism of exogenous shocks. We investigate whether or not this result holds under more standard assumptions. We Þnd that collateral constraints typically generate small(More)
The empirical evidence on income distribution for developing economies stands in contrast to the prediction of standard neoclassical trade theory according to which the skill premium should decrease in unskilled laborabundant countries following an opening to trade. This paper develops a dynamic, three-good, three-factor, general equilibrium model of a(More)
In this paper I suggest a uni...ed explanation for two puzzles in the inventory literature: ...rst, estimates of inventory speeds of adjustment in aggregate data are very small relative to the apparent rapid reaction of stocks to unanticipated variations in sales. Second, estimates of inventory speeds of adjustment in ...rm-level data are signi...cantly(More)
In spite of its low productivity, agriculture employs most of the labor force in countries in the lower part of the world income distribution. Moreover, agriculture differs from other activities in its intensive use of land. We show that ignoring agriculture, as most one-sector aggregate models do, gives rise to substantially biased results regarding the(More)
Dynastic altruistic models with endogenous fertility have been shown to be unable to generate enough intergenerational persistence. Using a Bewley model with endogenous fertility we show that it is possible to recover persistence. Key ingredients for our result include exponential child discounting, discrete number of children, diminishing costs of child(More)
I study the optimal taxation of families in an environment in which (i) characteristics of a family -labor productivity and desire for childrenare only observable by the family and (ii) child-rearing requires both goods and parental time. Potential parents simultaneously decide labor income and the family size. The government uses information on family(More)
