Product market regulation and employment protection are highly correlated across OECD countries. Using an augmented model of monopolistic competition we show why in countries with more regulated product markets, incumbent workers prefer to protect jobs relatively more. Product market regulation...

Collective dismissal costs are an important part of employment protection legislation (EPL) and make firms' exit more costly. We show in a model with step-by-step innovations that dismissal costs spur innovation if product markets are not too competitive: technologically more advanced firms...

We consider an economy where individuals privately choose effort and trade competitively priced securities that pay off with effort-determined probability. We show that if insurance against a negative shock is sufficiently incomplete, then standard functional form restrictions ensure that...

This paper analyzes the effect of labor and product market regulation in a dynamic stochastic equilibrium with search frictions. Modeling multiple-worker firms allows us to distinguish between the exit-and-entry (extensive) margin, and the hiring-and-firing (intensive) margin. We characterize...

In this paper we investigate the importance of labor market institutions such as unemployment insurance, unions, firing regulation and minimum wages for the evolution of wage inequality across countries. We derive a simple log-linear equation of the wage differential as a function of the...

Capital deepening may affect the evolution of the wage differential between skilled and unskilled workers differently in countries with different labor market institutions. If labor market institutions raise the relative wage of unskilled workers in Germany, firms have incentives to invest...

Interest rates on consumer lending are lower when funds are tied to purchase of a durable good than when they are made available on an unconditional basis. Further, dealers often choose to bear the financial cost of their customers’ credit purchases. This paper interprets this phenomenon in...

Defensive innovations in developed countries can explain the empirical phenomenon that openness towards trade with less-developed countries does not necessarily induce a substantial increase in the wage differential and trade volumes. Building on step-by-step innovations as introduced by Aghion...

We analyze dynamic interactions between market insurance, the stock of insurable assets and liquid wealth accumulation in a model with non-durable and durable consumption. The stock of the durable is exposed to risk against which households can insure. Since the model does not have a closed form...

Both personal bankruptcy and redistributive taxes can insure households’ consumption risk and both vary considerably across US states. We derive sufficient conditions under which more redistributive taxation makes bankruptcy exemptions less attractive both for the intratemporal insurance and...
