A number of behaviours influence health in a non-monotonic way. Physical activity and alcohol consumption, for instance, may be beneficial to one’s health in moderate but detrimental in large quantities. We develop a demand-for-health framework that incorporates the feature of a...

Unlike most studies of subjective well-being in developing countries, we use a fixed effects regression on three rounds of rich panel data to investigate the impact of relative standing on life satisfaction of respondents in urban Ethiopia. We find a consistently large negative impact of...

We investigate the relationship between intimate partner violence (IPV) and HIV among married women using Demographic and Health Survey data from ten sub-Saharan African countries, and find a strong association. The association is due to higher HIV risk among violent men; neither women’s...

This paper provides evidence on ability peer effects in university education. Identification comes from the random assignment of students to sections. We find that students on average benefit from better-ability peers. Low-ability students, however, are harmed by high-ability peers. We introduce...

We consider games where agents are embedded in a network of bilateral relationships and have multivariate strategy sets. Some components of their strategies correspond to individual activities, while the other strategic components are related to joint activities and interaction with the...

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...

When Romania and Bulgaria joined the EU in 2007 Sweden was one of two EU15 countries that did not restrict access to its labor market and welfare systems for Romanian and Bulgarian citizens. This article evaluates the net fiscal contribution in 2011 of Romanian and Bulgarian migrants who arrived...

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...
