Global environmental concerns have increased the sensitivity of governments and other parties to the actions of those outside their national jurisdiction. Parties have tried to extend influence extraterritorially both by promising to reward desired behavior and by threatening to punish undesired...

This paper assumes that workers can move from a market with high unemployment to one with low unemployment at a cost. In principle. equilibrium mobility can be greater or less than the social optimum. For most plausible parameter values. however. mobility is too low. Intuitively. mobility has a...

Public financing of private health insurance may generate external effects beyond the subsidized population, by influencing the size and bargaining power of health insurers. We test for this external effect in the context of Medicare Part D. We analyze how Part D-related insurer size increases...

Although the corrective tax has long been viewed by economists as a theoretically desirable remedy for the problem of harmful externalities, its actual use has been limited, mainly to the domain of pollution. Liability, in contrast, has great importance in controlling harmful externalities. I...

Taxation and liability are compared here as means of controlling harmful externalities. It is emphasized that liability has an advantage over taxation: inefficiency of incentives arises under taxation when, as would be typical, it would be impractical for a tax to reflect all variables that...

Generating electricity from renewable sources is more expensive than conventional approaches, but reduces pollution externalities. Analyzing the tradeoff is much more challenging than often presumed, because the value of electricity is extremely dependent on the time and location at which it is...

We use changes in Brazil's tax on capital inflows from 2006 to 2011 to test for direct portfolio effects and externalities from capital controls on investor portfolios. The analysis is structured based on information from investor interviews. We find that an increase in Brazil's tax on foreign...

This paper shows that in a small open economy model with downward nominal wage rigidity pegging the nominal exchange rate creates a negative pecuniary externality. This peg-induced externality is shown to cause unemployment, overborrowing, and depressed levels of consumption. The paper...

We illustrate the welfare benefit of tax subsidies to corporate debt financing. Two firms engage in a socially wasteful competition for survival in a declining industry. Firms differ on two dimensions: exogenous productivity and endogenously chosen amount of debt financing, resulting in a two...
