This Paper shows that price rigidity evolves in an economy populated by imperfectly rational agents who experiment with alternative rules of thumb. In the model, firms must set their prices in the face of aggregate shocks. The payoff depends on the level of aggregate demand, as well as on their...

This paper studies the effect of economic integration of two regions on the mobility of skilled and unskilled workers across regions and on the resulting location of industrial activity. In particular, it studies what happens when wages in both regions are set by the unions of the ‘West’ –...

This paper shows that multiple growth paths may occur in a politico-economic model of endogenous growth. This multiplicity is characterized by the coexistence of a low-tax, low-capital-flight equilibrium and a high-tax, high-capital-flight equilibrium. The likelihood of multiplicity is crucially...

In an overlapping generations model, rents to human capital play a key role in increasing savings. In the absence of such rents, the return to human capital is entirely appropriated by the old and accumulation is entirely determined by the income to fixed factors. If rents are introduced by...

We study and endogenous growth model where a profit-motivated R&D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones, which are produced by a monopoly owned by the inventor. We show that...

The distributional effects of the minimum wage are analyzed in a model where skilled and unskilled labor enter the production function. It is argued that distributional goals are best achieved by letting the labor market clear and achieving redistribution through taxes and transfers

This paper develops a matching model of the labor market under wage rigidity when hiring decisions are irreversible. There are two types of workers, the skilled and the unskilled. The model is used to analyze whether technological advances may have increased unemployment. It is shown that it is...

We develop a model to analyze the implications of firing costs on incentives for R & D and international specialization. The key idea is that, to avoid paying firing costs, the country with a rigid labor market will tend to produce relatively secure goods, at a late stage of their product life...

The Jewish Social Contract begins by asking how a traditional Jew can participate politically and socially and in good faith in a modern democratic society, and ends by proposing a broad, inclusive notion of secularity. David Novak takes issue with the view--held by the late philosopher John...
