Difference-in-differences with matching is a popular method in impact evaluation. Traditional impact evaluation methods including difference-in-differences with matching often deal with impact measurement of a single binary program. Imbens (1999) and Lechner (2001) extend the matching method to...

Most existing semi-parametric estimation procedures for binary choice models are based on the maximum score, maximum likelihood, or nonlinear least squares principles. These methods have two problems. They are difficult to compute and they may result in multiple local optima because they require...

The impact of trade liberalization on productivity and economic growth has received considerable attention in recent policy debate. Besides the theory, there is also a large body of empirical literature on the impact of trade policy reforms on productivity growth. We contribute to this...

This paper presents an overview of several widely-used methods in program impact evaluation. In addition to a randomization-based method, these methods are categorized into: (i) methods assuming “selection on observable” and (ii) methods assuming “selection on unobservable”. The paper...

Traditional literature on impact evaluation often deals with binary programs. In reality, a program can provide different amounts of treatment for people, and it is regarded as a continuous variable. This paper discusses impact evaluation of a continuous program using matching methods and...

Microcredit has been shown to be effective in reducing poverty in many developing countries. However, less is known about its effect on human capital formation. In this paper, we develop a model examining the relation between microcredit and child labour. We then empirically examine the impact...

This paper assesses the causal effect of relaxing equity constraints on the cultivation of tobacco in Malawi, a crop viewed by the local population as Malawi’s green gold. Applying the counterfactual outcome framework we find that relaxing equity constraints substantially increases the amount...

We study the behavior and interaction of systematic and idiosyncratic components of risk in a cross-section of U.K. stocks. We find no clear evidence of a trend in any component of total risk, but we document different “regimes” in the behavior of each component of total risk, in their...

The relationship between calorie and nutrient (fat, protein, and carbohydrates) intake as a function of income is explored using data for 171 countries over two time periods 1990-1992 and 2003-2005. Three types of analysis are employed: i) nonparametric, ii) panel regressions, and iii) quantile...

Estimation of causal eects in regression discontinuity designs relies on a local Wald estimator whose components are estimated via local linear regressions centred at an specic point in the range of a treatment assignment variable. The asymptotic distribution of the estimator depends on the...
