What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore cross-country spillovers of tax...

I examine optimal taxes in an overlapping generations economy in which each consumer's utility depends on consumption relative to a weighted average of consumption by others (the benchmark level of consumption) as well as on the level of the consumer's own consumption. The socially optimal...

We study optimal monetary and fiscal policy in a model with heterogeneous agents, incomplete markets, and nominal rigidities. We develop numerical techniques to approximate Ramsey plans and apply them to a calibrated economy to compute optimal responses of nominal interest rates and labor tax...

This paper explores the trade-off between incentive effects and administrative costs associated with the implementation of various environmental tax instruments, with special reference to carbon taxes. In a simple model, we show under what conditions it is optimal to use input rather than...

This paper examines 'traditional' (non-environmental) efficiency consequences and environmental effects of two energy tax policies: a tax on fossil and synthetic fuels based on Btu (or energy) content and a tax on consumer purchases of gasoline. It uses a model that uniquely combines attention...

This paper shows that the output losses from energy taxes are significantly larger than usually computed when due account is taken of imperfect competition among energy using firms. Even with perfect competition among these firms, the loss in GNP is of the same order of magnitude as the revenue...

How can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention? I derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand, the size of the price change, and the degree of...

This paper provides a theoretical analysis of optimal minimum wage policy in a perfectly competitive labor market. We show that a binding minimum wage -- while leading to unemployment -- is nevertheless desirable if the government values redistribution toward low wage workers and if unemployment...
