This paper proposes a theoretical explanation of the empirical finding that private consumption increases in response to an increase in government spending. The explanation requires two ingredients. First, labor demand expands (e.g. prices are sticky). Second, general non-separable preferences...

We study the incentives of parents to invest in their children when these investments improve their marriage prospects, in a frictionless marriage market with non-transferable utility. Stochastic returns to investment eliminate the multiplicity of equilibria that plagues models with...

A growing economic literature stresses the importance of relative comparisons, e.g., for savings and consumption or happiness. In this literature it is usually assumed that reference standards against which people compare themselves are exogenously given. In contrast, findings from social...

Consumers, when buying health insurance, do not know the exact value of each treatment that they buy coverage for. This leads them to overvalue some treatments and undervalue others. We show that the insurance market cannot correct these mistakes. This causes research labs to overinvest in...

What structure of income taxation maximizes the social benefits of redistribution while minimizing the social harm associated with distorting the allocation of labor input? Many authors have advocated scrapping the current tax system, which redistributes primarily via marginal tax rates that...

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...

We study dynamic optimal taxation in a class of economies with private information. Constrained optimal allocations in these environments are complicated and history-dependent. Yet, we show that they can be attained as competitive equilibria in market economies supplemented with simple tax...

We analyse how, in representative democracies, income distribution influences the stringency of environmental policy and economic growth. Individuals (who differ in abilities) live for two periods, working when young and owning capital when old. Externalities are caused by a polluting factor....

Emission taxes under oligopoly with both fixed number and endogenous market structure (perhaps the most relevant market structures for policy issues) are examined. In the latter case, and contrary to what is expected under imperfect competition, the optimal tax could exceed marginal external...

The fact that according to the celebrated Coase theorem rational parties always try to exploit all gains from trade is usually taken as an argument against the necessity of government intervention through Pigouvian taxation in order to correct externalities. We show that the hold-up problem,...
