Teams Promise but Do Not Deliver

Individuals and two-person teams play a hidden-action trust game with pre-play communication. We replicate previous results for individuals that non-binding promises increase cooperation rates, but this does not extend to teams. While teams promise to cooperate at the same rate as individuals, they consistently renege on those promises. Additional treatments begin to explore the basis for team behavior. ...

Decentralization and Public Procurement Performace: New Evidence from Italy

We exploit a new dataset based on European Union (EU) procurement award notices to investigate the relationship between the degree of centralization of public procurement and its performance. We focus on the case of Italy, where all levels of government, along with a number of other public institutions, are involved in procurement and are subject to the same EU regulation. We find that (a) municipalities ...

The Effect of Restructuring Electricity Distribution Systems on Firms' Persistent and Transient Efficiency

We evaluate the efficiency of electricity distribution operators (DSOs) as providers of local public infrastructure. In particular, we consider two types of efficiency, i.e., short-term (transient) and long-term (persistent). We apply the recently developed four-component stochastic frontier model, which allows identifying determinants of the two types of efficiency, after controlling for firm heterogeneity ...

Early Education and Care Quality: Does It Matter for Maternal Working Hours?

This study investigates whether mothers whose children enter early childhood education and care (ECEC) centers of higher quality are more likely to work longer hours. The empirical analysis links the Socio-Economic Panel (SOEP) Study with the K2iD-SOEP extension study, which collected ECEC quality information from childcare centers across Germany. Based on a sample of 556 mothers of 628 children with ...

Is There Still Son Preference in the United States?

In this paper, we use 2008-2013 American Community Survey data to update and further probe evidence on son preference in the United States. In light of the substantial increase in immigration, we examine this question separately for natives and immigrants. Dahl and Moretti (2008) found earlier evidence consistent with son preference in that having a female first child raised fertility and increased ...

Looking for the Missing Rich: Tracing the Top Tail of the Wealth Distribution

We analyse the top tail of the wealth distribution in France, Germany, and Spain using the first and second waves of the Household Finance and Consumption Survey (HFCS). Since top wealth is likely to be under-represented in household surveys, we integrate big fortunes from rich lists, estimate a Pareto distribution, and impute the missing rich. In addition to the Forbes list, we rely on national rich ...
