The attractiveness of high-technology companies for skilled, creative and international talent is one of the most important factors for their global competitiveness. Recent research shows that highly skilled people increasingly demand their work place to be a place to work, live and socialize -...

This note adapts results by Huang and Hidiroglou (2003) on Generalized Least Squares estimation and Empirical Bayes prediction for linear mixed models with sampling weights. The objective is to incorporate these results into the poverty mapping approach put forward by Elbers et al. (2003). The...

For reason of empirical tractability, analysis of cointegrated economic time series is often developed in a partial setting, in which a subset of variables is explicitly modeled conditional on the rest. This approach yields valid inference only if the conditioning variables are weakly exogenous...

"The Impact of Microcredit on the Poor in Bangladesh: Revisiting the Evidence,"by David Roodman and Jonathan Morduch (2014) (henceforth RM) is the most recent of a sequence of papers and web postings that seeks to refute the findings of the Pitt and Khandker (1998; henceforth PK) article"The Impact...

This paper formalizes the design of experiments intended specifically to study spillover effects. By first 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 can be...

Using a global panel on research and development (R&D) expenditures, this paper documents that on average poor countries do far less R&D than rich as a share of GDP. This is arguably counter intuitive since the gains from doing the R&D required for technological catch up are thought to be very...

This paper examines the association between the intensity, timing, and persistence of personal history of mobility on individual support for redistribution. Using both rounds of the Life in Transition Survey, the paper builds measures of downward mobility for about 57,000 individuals from 27...

Incorporating qualitative methods into the evaluation of development programs has become increasingly popular in recent years, both for the distinctive insights such approaches can bring in their own right and because of their capacity to complement the strengths -- and where necessary correct...
