How much information should governments reveal to consumers if consumption choices have uninternalized consequences to society? How does an alternative tax policy compare to information disclosure? We develop a price theoretic model of information design that allows empiricists to identify the...

Non-pecuniary incentives motivated by insights from psychology (“nudges”) have been shown to be effective tools to change behavior in a variety of fields. An often unanswered question relevant for public policy is whether these promising interventions can be scaled up. In cooperation with a...

Conflicting societal goals can lead to national and local policies that are at odds with each other. National policies promoting the adoption of solar photovoltaics may be counteracted by local policies defining the aesthetics of the built environment. As solar photovoltaic energy approaches...

The paper assesses the distributional and efficiency/disincentive aspects of the Greek indirect tax system, which provides 60% of total tax revenue. The marginal welfare costs of broad commodity groups were computed to identify welfare-improving directions of reform. The disincentive effects...

The theory of road pricing developed for single links suggests time andlocation varying charges equal to the marginal congestion cost at the efficientlevel of traffic. The second-best network counterpart is derived, but would beinfeasible to implement. Cordon tolls are feasible, and their...
