Regression Discontinuity (RD) models identify local treatment effects by associating a discrete change in an outcome with a corresponding discrete change in the probability of treatment at a known threshold of a running variable. This paper shows that it is possible to identify RD model...

Regression Discontinuity (RD) models identify local treatment effects by associating a discrete change in the mean outcome with a corresponding discrete change in the probability of treatment at a known threshold of a running variable. This paper shows that it is possible to identify RD model...

If dryland legumes are to meet the expectations of reducing poverty and hunger in the semi-Arid Tropics, there will be need for a full understanding of their potential for diffusion and the barriers to adoption. We apply a program evaluation technique to data obtained from Tanzania to derive...

In the literature on program impact evaluation, the popular impact parameters can the average treatment effect, the average treatment effect on the treated, the average partial effect, and the average partial effect on the treated. In empirical studies, these parameters are not always presented...

Training programs are an important tool of human resource management, especially in case of technological and organizational changes inside a company. According to the human capital theory, trainings generally lead to increased post-training wages. Having this into consideration, this paper aims...

This article is an empirical study of residential land values in the vicinity of the TransMilenio system (Bus Rapid Transit, BRT) in Bogota´ (Colombia). The results have been established through impact evaluation by means of nonparameteric approaches (Propensity Score Matching, PSM) and...

We apply propensity score matching (PSM) to the estimation of household motor fuel purchase quantities, to tackle problems caused by infrequency of purchase. The results are compared to an alternative, regression-based, imputation strategy using the infrequency of purchase model (IPM). Using...

The purpose of this paper is to analyze the impact of trust-based relations on firm’s performance in transition economies. The trade credit variable is used as a proxy of trust-based relations and the propensity score matching method is employed to establish casual link between relational...

Discrimination is a significant issue in labour market economics across developed as well as developing countries. In this paper we inquire the actual size of wage discrimination in the Republic of Soutn Africa, accounting for large differences in individual endowments. We apply the...

We examine the employment effects of international outsourcing by using firm-level data from the Finnish manufacturing sector. A major advantage of our data is that outsourcing is defined based on firms’ actual use of intermediate inputs from foreign trade statistics. The estimates show that...
