In this article, we use a unique database on 542 villages in southwestern Darfur to analyze patterns of population growth and land reallocation that have emerged as a consequence of the recent conflict. Our analysis demonstrates that a displacement from this region alone of more than 300,000...

This paper carries out a critical reappraisal of the two contending theories purporting to explain long-run government spending: Wagner’s Law and different variants of the ratchet effect. We analyze data spanning from the early 19th century until the present day in Sweden and the United...

Trees have multiple purposes in rural Ethiopia, providing significant economic and ecological benefits. Planting trees supplies rural households with wood products for their own consumption, as well for sale, and decreases soil degradation. In this paper, we used cross-sectional household-level...

We examine the influence of guilt and trust on the performance of credence goods markets. An expert can make a promise to a consumer first, whereupon the consumer can express her trust by paying an interaction price before the expert's provision and charging decisions. We argue that the expert's...

This paper examines the relationship between immigrant occupational composition and wages in Sweden. Effects of changes in proportion of immigrant workers in different occupations on the wage levels of both natives and immigrants are estimated. Our results suggest that increases in immigrant...

In this paper we try to explain the academic performance of a sample of children starting their first year at public schools in 1999 in Montevideo, Uruguay. We are mainly interested in the effect of pre-school education on the children’s academic results. We found fairly strong empirical...

We develop a conflict model linking dissipation to the distribution of the population over an arbitrary number of groups. We extend the pure contest version of the model by Esteban and Ray (1999) to include a mixed public-private good. We analyze how the level of dissipation changes as the...

This paper proposes a new unit root test in the context of a random autoregressive coefficient panel data model, in which the null of a unit root corresponds to the joint restriction that the autoregressive coefficient has unit mean and zero variance. The asymptotic distribution of the test...

This paper proposes two new unit root tests that are appropriate in the presence of an unknown number of structural breaks. One is based on a single time series and the other is based on a panel of multiple series. For the estimation of the number of breaks and their locations, a simple...

In practice, targeted monitoring seems to be a strategy frequently used by regulators. In this paper, we study the effects of targeted monitoring strategies on the adoption of a new abatement technology and, consequently, on the aggregate emissions level when firms are regulated with uniform...
