The design of environmental spending at the national or local level stands on the concept of subsidiarity and on the theory of fiscal federalism. The main question is, so forth, studying when centralization of a public economic function, such as the protection of the environment, is welfare...

Our hypothesis: during the twentieth century governments used state emergency measures to overcome its economic crisis. Such measures did better on the revenue in fiscal expenditures, thereby caused severe imbalances of public policy. It holds that in Colombia there has been no welfare state...

Tax compliance can be affected by many factors such as magnitude of compliance cost, the extent of penalty, perceived fairness of the tax system, awareness level of taxpayers and perceptions of government spending. The purpose of the study is identifying factors that affect compliance of...

This paper analyzes optimal taxation of charitable giving to a public good in a Mirrleesian framework with social comparisons. Leisure separability together with zero transaction costs of giving imply that charitable giving should be subsidized to such an extent that governmental contributions...

This paper deals with tax policy responses to charitable giving based on a model of optimal redistributive income taxation. The major contribution is the simultaneous treatment of (i) warm-glow and stigma effects of charitable donations; (ii) that the warm glow of giving and stigma of receiving...

A large tax wedge can lead to a dramatic increase in economic efficiency. The market share of 'deadweight loss' produced by a tax wedge consists of inefficient producers and indifferent consumers. The high costs in resources involved in production of the relatively small quantity of 'deadweight...

We study optimal linear income taxation in a model with heterogeneous agents where earnings potentials are endogenously determined through human capital accumulation. Agents differ in initial conditions and ability to learn. Capital market imperfections prevent poor agents to invest optimally in...

Using a general equilibrium model with heterogeneous waste, this paper studies optimal waste policy when households have to exert separation effort to produce near-homogeneous waste streams suitable for recycling. Our model explicitly allows for changes in the composition (quality) of waste...

This paper investigates optimal airport pricing when airlines provide imperfect substitutes products, and make decisions on capacity, scheduling and pricing. We show that the first-best toll per flight may be higher than the simple market-shares formulae that were recently derived for Cournot...

In this paper I sketch out the rough contours of the challenge faced by the WTO in dealing with non-tariff measures (NTMs) as seen from the economic theories of trade agreements. The key questions for the WTO - the answers to which largely dictate the choice between shallow and deep approaches...
