This paper derives Pareto efficient policy rules for the provision of national as well as global public goods in a two-country world, where each individual cares about relative consumption within as well as between countries. Furthermore, we compare these policy rules with those that follow from...

This paper examines power issues for the ADF and four break models (Perron 1989, Zivot and Andrews 1992) when the DGP corresponds to one of the break models. Choosing to test an incorrect break model can but need not greatly reduce the probability of rejecting the null. Break points that are...

This paper integrates soil science variables into an economic analysis of agricultural output among small-scale farmers in Kenya’s highlands. The integration is valuable because farmers’ choice of inputs depends on both the status of the soil and socio-economic conditions. The study uses a...

We use panel data from rural Ethiopia to investigate if participation in a safety net program enhances fertilizer adoption. Using a difference-in-difference estimator and inverse propensity score weighting we find that participation in Ethiopia’s food-for-work program increased fertilizer...

This article studies second-degree price-discrimination in markets for credence goods. Such markets are affected by asymmetric informationbecause expert sellers are better informed than their customers about the quality that yields the highest surplus from trade. We show that discrimination...

This paper studies how different NOx abatement technologies have diffused under the Swedish system of refunded emissions charges and analyzes the determinants of the time to adoption. The policy, under which the charge revenues are refunded back to the regulated firms in proportion to energy...

The optimal provision of a state-variable public good, where the global climate is the prime example, is analyzed in a model where people care about their relative consumption. We consider both keeping-up-with-the-Joneses preferences (where people compare their own current consumption with...

We examine the impact of the 2004 Indian tsunami on international remittance transfers using aggregate country data and synthetic control methodology. This procedure implies identifying the causal impact of the disaster by comparing the share of remittances to GDP in Indonesia, the country most...

Providing health insurance involves a trade-off between the benefits from risk spreading and the costs due to moral hazard. Focusing on pharmaceuticals consumption, this paper examines theoretically whether reference pricing, requiring individuals to pay the price difference if, in this case,...
