In contrast to recent literature, we show that market access requirements (MARs) can be implemented in a procompetitive manner even in the absence of threats in related markets. By focusing on subsidies that are paid only when the requirement is met, we show that a MAR can increase aggregate...

Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

In oligopolistic situations content protection can have unexpected effects as it changes the nature of interactions between input suppliers. With a duoply, it does so in a manner that makes the foreign firm wish to match price increases and decreases of the domestic firm. Domestic input...

This paper deals with the effect of trade restrictions on competition in oligopolistic markets. Quantitative restrictions, such as VER's (Voluntary Export Restrictions) are shown to affect the extent to which foreign firms can compete in the domestic market, and hence to raise the equilibrium...

Thereare three points made in this paper. The first is that the question concerning choice of a product line by a monopolist is similar in structure to other adverse selection problems -- and can be analyzed in an elementary way by adapting techniques recently developed for such problems. Such...

The prospect of capital obsolescence inhibits investment. Investors thus become more optimistic when the obsolescence of their capital slows down. We propose a model with no fixed costs of investment, and random technological progress that induces obsolescence of capital in place. Spikes occur...

We study the effects of parameter uncertainty prompted by structural breaks. In our model, agents respond differently to uncertainty prompted by regime shifts in shock processes than they react to comparable perceived increases in shock volatility. The magnitude of the response to an increase in...

We study private equity in a dynamic general equilibrium model and ask two questions: (i) Why does the investment of venture funds respond more strongly to the business cycle than that of buyout funds? (ii) Why are venture funds returns higher than those of buyout? On (i), venture brings in new...

The computable general equilibrium models used in the literature tend to be a bit of a black box. This paper provides some intuition behind what goes on in these black boxes by laying out a simple general equilibrium model and intuitively explaining what lies behind the demand for emissions. It...

This paper proposes a new test of the Protection for Sale (PFS) model by Grossman and Helpman (1994). Unlike existing methods in the literature, our approach does not require any data on political organizations. We formally show that the PFS model predicts that the quantile regression of the...
