This paper uses data from the Greater Avenues for Independence (GAIN) initiative to discuss the evaluation of programs that are implemented at multiple sites. Two frequently used methods are to pool the data or to use fixed effects (an extreme version of which estimates separate models for each...

En un sistema formado por una red de nodos emisores y receptores de información, es necesario conocer el estado de señal que tendría cada uno de esos nodos en todo momento con el fin de lograr un flujo de información adecuado. El objetivo de este trabajo es obtener un modelo matemático que...

Despite the importance of trade facilitation as an area of trade and development policy, there have been very few impact evaluations of specific trade facilitation reforms. This paper offers an evaluation of in-house clearance, a reform that allows qualified firms in Serbia to clear customs from...

We study optimal transport networks in spatial equilibrium. We develop a framework consisting of a neoclassical trade model with labor mobility in which locations are arranged on a graph. Goods must be shipped through linked locations, and transport costs depend on congestion and on the...

This paper employs network analysis to study world trade from 1995 to 2014. We focus on the main connective features of the world trade network (WTN) and their dynamics. Results suggest that countries' efforts to attain the benefits of trade have resulted in an intertwined network that is...

Longitudinal network data are increasingly available, allowing researchers to model how networks evolve over time and to make inference on their dependence structure. In this paper, a dynamic latent space approach is used to model directed networks of monthly interbank exposures. In this model,...

Ohne weitere Effizienzsteigerungen sind Krankenhäuser in Deutschland langfristig weder dem finanziellenDruck noch den Herausforderungen des demographischen Wandels gewachsen. Zur Unterstützung von Ressourcenkapazitätsentscheidungen auf strategischer, taktischer und operativer Ebene wird in...

"Site selection bias" can occur when the probability that a program is adopted or evaluated is correlated with its impacts. I test for site selection bias in the context of the Opower energy conservation programs, using 111 randomized control trials involving 8.6 million households across the...
