For policy purposes, it is important to understand the relative efficacy of various methods to target the poor. Recently, participatory methods have received particular attention. We ex-amine the effectiveness of a hybrid two-step process that combines a participatory wealth ranking and a...

Accurate measurement of stock levels, turnover, and profitability in microenterprises in developing countries is difficult due to the fact that the majority of these firms do not keep detailed records. We test the use of RFID tags as a means of objectively measuring stock levels and stock flow...

We study the design of randomized controlled experiments in environments where outcomes are significantly affected by unobserved effort decisions taken by the subjects (agents). While standard randomized controlled trials (RCTs) are internally consistent, the unobservability of effort provision...

We study the recent evolution of top incomes in Switzerland, analyzing both social security data on labor incomes and tax data on total income. The results show that in the last 20 years, the share of top incomes has risen, and the top 0.01 percent’s share even doubled, putting Switzerland...

This paper investigates the determinants of group membership, and in particular the effect of income inequality on individual incentives to join economic groups. Drawing on a simple model, we show that an increase in inequality has an ambiguous effect and that the type of access rule (open...

This paper examines the implications of labour force growth in one region for wages, employment, and production patterns in other regions. These issues are first explored in a stylized dual model incorporating features of both standard factor-based trade models and models of two-way trade and...

This paper constructs a simple model of the steel sector in Europe distinguishing eight West and two East European regions. It models the production of steel and also the various trade restrictions extant in 1992. It uses this model first to calculate the output and welfare effects of...

This study shows that Target2 net claims are a poor measure of Bundesbank loss exposure, and even more so of German loss exposure to the rest of the Eurozone. This is true even under plausible assumptions about a comprehensive break-up scenario that leaves Germany as the only member of the euro...

Comparisons of economic performance over space and time largely depend on how statistical evidence from national accounts and historical estimates are spliced. To allow for changes in relative prices, GDP benchmark years in national accounts are periodically replaced with new and more recent...

This paper looks at the channels through which intangible assets affect productivity. The econometric analysis exploits a new dataset on intangible investment (INTAN-Invest) in conjunction with EUKLEMS productivity estimates for 10 EU member states from 1998 to 2007. We find that (a) the...
