Taking advantage of a unique quasi-experi-mental survey design, this study analyzes the productivity impacts of the Ethiopian land certification program by identify-ing how the investment effects (technological gains) would measure up against the benefits from any improvements in input use...

This paper follows a quasi-experimental research design to assess the impact of the electronic payment system of Mexico.s Oportunidades programme. The switch from cash payments to electronic payments delivered via a bank account is found to have implicati

This paper formalizes the design of experiments intended speciï¬cally to study spillover effects. . By ï¬rst randomizing the intensity of treatment within clusters and then randomly assigning individual treatment conditional on this cluster-level intensity, a novel set of treatment effects...

We introduce a canonical representative for the isomorphism classes of non-regular orthogonal arrays based on the generalized wordlength patterns (GWLP) of delete-one-factor projections. These GWLP values have been used recently to introduce a fast isomorphism test for two-level regular arrays....

This paper follows a quasi-experimental research design to assess the impact of the electronic payment system of Mexico's Oportunidades programme. The switch from cash payments to electronic payments delivered via a bank account is found to have implications in terms of reallocation between...

Consumer products and services can often be described as mixtures of ingredients. Examples are the mixture of ingredients in a cocktail and the mixture of different components of waiting time (e.g., in-vehicle and out-of-vehicle travel time) in a transportation setting. Choice experiments may...

Background: Experimental designs constitute a vital component of all Stated Choice (aka discrete choice experiment) studies. However, there exists limited empirical evaluation of the statistical benefits of Stated Choice (SC) experimental designs that employ non-zero prior estimates in...
