This paper analyzes deforestation in areas of overlapping land tenure in the northern Ecuadorian Amazon. We use a random coefficients model to test for differences in forest cover across tenure forms over time. Tenure categories are significantly associated with changes in deforestation, even...

Managing harvests from natural resource systems is often seen as necessary to recover resource rent, that is, for wise and sustainable use. This paper develops a method to estimate resource rent recovery for a class of nontimber forest products and, using a unique dataset on the harvest of wild...

Value and momentum portfolios exhibit strong opposite signed exposure to an aggregate risk factor based on low frequency fluctuations in the capital share. This strong opposite signed exposure helps explain why both strategies earn high average returns yet are negatively correlated. But the...

Value and momentum strategies earn persistently large return premia yet are negatively correlated. Why? We show that a quantitatively large fraction of the negative correlation is explained by strong opposite signed exposure of value and momentum portfolios to a single aggregate risk factor...

Most national health surveys do not permit precise measurement of the health of racial/ethnic subgroups that comprise 1 per cent of the U.S. population. We identify three potentially promising sample design strategies for increasing the accuracy of national health estimates for a small target...
