Estimation, inference and interpretation of the causal effects of programs and policies have all advanced dramatically over the past 25 years. We highlight three particularly important intellectual trends: an improved appreciation of the substantive importance of heterogeneous responses and of...

This paper shows that the Conditional Quantile Treatment Effect on the Treated can be identified using a combination of: (i) a conditional Distributional Difference in Differences assumption and, (ii) an assumption on the conditional dependence between the change in untreated potential outcomes...

This paper proposes a method to estimate treatment effects in difference-in-differences designs in which the treatment start is staggered over time and treatment effects are heterogeneous by group, time, and covariates, and when the data are repeated cross-sections. We show that a...

This study investigates the effects of public policy supports on the export performance of bioenergy technologies; it uses panel data from 18 countries from the 1992 to 2008 period. Panel unit-root and cointegration tests are applied, taking into account the results of structural-break tests for...

The aim of this article is to investigate the causal relationship between remittances and poverty reduction for 14 emerging and developing countries over the period 1980 - 2012. We proposed a cointegration analysis, using the method of non-stationary dynamic panel data. Our estimation results...

In this paper, we revisit the inequality-growth relationship using an enhanced panel data set with improved inequality data and special attention to the role of transition countries. We base our analysis on the specification of Forbes (2000), but also address the functional form concerns raised...
