How does the size of the transfer system evolve in the short and in the long run? We construct a model where taxation is distortionary because it discourages capital accumulation. We compare the Ramsey allocation with the time-consistent allocation. The latter can be interpreted as the outcome...

Market work per person is roughly 10 percent higher in the U.S. than in Sweden. However, if we include the work carried out in home production, the total amount of work differs by only 1%. I set up a model with home production and show that differences in policy - mainly taxes - can account for...

The question of how technological change affects labor markets is a classical one in macroeconomics. A standard framework for addressing this question is the matching model with vintage capital and exogenous technical progress. Within this framework, it has been argued that the impact of...

To study the political economy of immigration, we develop a common agency model where a trade union and a lobby of entrepreneurs offer contributions to the government to influence its decision on how many immigrants can enter the domestic economy. In the political equilibrium, anticipating that...

Many countries run substantial inflations. They do this despite the overwhelming theoretical arguments (and empirical evidence?) showing that price stability (or even mild deflation) is "better." This paper provides a simple model in which a government sometimes uses the inflation tax because it...

This paper uses a seminonparametric model and Consumer Expenditure Survey data to estimate life cycle profiles of consumption, controlling for demographics, cohort and time effects. In addition to documenting profiles for total and nondurable consumption, we devote special attention to the age...

Tobin's Q exceeds one, even without any adjustment costs, for a firm that earns rents as a result of monopoly power or of decreasing returns to scale in production. Even when there are no adjustment costs and marginal Q is always equal to one, Tobin's Q is informative about the firm's growth...

Economies respond differently to aggregate shocks that reduce output. While some countries rapidly recover their pre-crisis trend, others stagnate. Recent studies provide empirical support for a connection between aggregate growth and plant dynamics through their effect on productivity: the...

We construct a bilateral search model of the housing market in which agents differ in their flow rewards while searching. Buyers and sellers enter the market with high flow rewards, but move at a Poisson rate to a state with low flow rewards if they do not transact in the meantime. We...

The paper sets out a monetary business cycle model extended to include the production of credit that serves as an alternative to money in transactions and is subject to productivity shocks. The model provides some improvement on certain puzzles, in particular by capturing the procyclic movements...
