In many parts of the world, soils poor in nutrients are farmed with little addition of fertilizer, further depleting the farmland. The very same farmers often face poor sanitary solutions. So-called ecological sanitation aims at providing sanitation and at recycling nutrients as fertilizer. This...

When a public good is excludable it is possible to charge individuals for using the good. We study the role of prices on excludable public goods within an extension of the Stern-Stiglitz version of the Mirrlees optimal income tax model. Our discussion includes both the case where the public good...

This paper addresses optimal taxation, when the relationship between consumption and environmental damage is uncertain and treated as a random variable by policy makers. The main purpose is to analyze how additional uncertainty about this relationship affects the optimal unit tax on the...

In this paper we study the consequences of endogenous active labor market policies. In particular it is assumed that all viable policies have to please the employed majority. The main objective is to seek the answer to the following question: In what sense does the political equilibrium deviate...

This paper addresses transboundary environmental problems in the context of an optimal tax problem, when part of the labor force is mobile across countries. The policy instruments include both commodity taxation and nonlinear income taxation. We show how the tax policy in a noncooperative...

Should unemployment compensation be paid indefinitely at a fixed rate or should it decline (or increase) over a worker’s unemployment spell? We examine these issues using an equilibrium model of search unemployment. The model features worker-firm bargaining over wages, free entry of new jobs,...

The paper discusses which redistributional policies are efficient when the identity of the high and low skill persons is private information. Our major purpose is to identify the more efficient policy when, presumably for administrative reasons, the policy option is confined to the choice...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...

Several contributions in the optimal taxation literature have emphasized that, when individuals’ preferences are not separable between leisure and other goods, it is desirable to supplement a nonlinear income tax with public provision of private goods. Moreover, it has also been shown that the...
