This paper evaluates the ex-post impact of adopting improved groundnut varieties on crop income and rural poverty in rural Uganda. The study utilizes cross-sectional farm household data collected in 2006 in seven districts of Uganda. We estimated the average adoption premium using propensity...

The Altham statistic is often used to calculate intergenerational associations in occupations in studies of historical social mobility. This paper presents a method to incorporate individual covariates into such estimates of social mobility, and to construct corresponding confidence intervals....

Weather and temperatures vary in ways that are difficult to explain and predict precisely. In this article we review data on temperature variations in the past as well possible reasons for these variations. Subsequently, we review key properties of global climate models and statistical analyses...

This study assesses the potential cost-effectiveness of incentive payment programs relative to traditional top-down regulatory programs for biological conservation. We develop site-level estimates of the opportunity cost and the nonmonetized biological benefits of protecting biodiversity...

We study the effects of various environmental regulations on environmental performance measured as emission intensity. Moreover, we aim to test whether any such effects are persistent or only temporary. Conventional theory predicts that indirect regulations as opposed to direct regulations...

We evaluate how nonresponse affects conclusions drawn from survey data and consider how researchers can reliably test and correct for nonresponse bias. To do so, we examine a survey on labor market conditions during the COVID-19 pandemic that used randomly assigned financial incentives to...

Soil fertility depletion is considered the main biophysical limiting factor to increasing per capita food production for most smallholder farmers in Africa. The adoption and diffusion of sustainable agricultural practices (SAPs), as a way to tackle this impediment, has become an important issue...

This paper analyzes estimators based on the instrumental variable quantile regression (IVQR) model (Chernozhukov and Hansen, 2004, 2005, 2006) under the local quantile treatment effects (LQTE) framework (Abadie et al., 2002). I show that the quantile treatment effect (QTE) estimators in the IVQR...

This paper studies estimation of conditional and unconditional quantile treatment effects based on the instrumental variable quantile regression (IVQR) model (Chernozhukov and Hansen, 2004, 2005, 2006). I introduce a class of semiparametric plug-in estimators based on closed form solutions...

Abstract Standard economic models predict that individuals smooth consumption over the life cycle. In contrast, there exists controversial empirical evidence showing that consumption declines at retirement. This paper investigates whether there is evidence for this so-called Retirement...
