In the 1980s, many U.S. cities initiated programs reserving a proportion of government contracts for minority-owned businesses. The staggered introduction of these set-aside programs is used to estimate their impacts on the self-employment and employment rates of African-American men. Black...

This paper assesses the effects of changes in scoring weights in auctions, using a unique sample of biddings of private Welfare-to-Work (WTW) organizations to reintegrate groups of unemployed and disabled workers. WTW-organizations did not only bid on prices, but also received points for three...

In this paper we assess the effectiveness of a social public procurement policy in Switzerland that gives firms that train apprentices a preferential treatment. We estimate the effectiveness of this social procurement policy on a firm's training participation, training intensity, and training...

Public support of research typically relies on the notion that universities are engines of economic development, and that university research is a primary driver of high wage localized economic activity. Yet the evidence supporting that notion is based on aggregate descriptive data, rather than...

In 1997, Australia implemented a gun buyback program that reduced the stock of firearms by around one-fifth. Using differences across states in the number of firearms withdrawn, we test whether the reduction in firearms availability affected firearm homicide and suicide rates. We find that the...

We investigate the relationship between the time politicians stay in office and the functioning of public procurement. To this purpose, we collect a data set on the Italian municipal governments and all the procurement auctions they administered between 2000 and 2005. Identification is achieved...

This paper examines the relationship between product demand and the pattern of rising skill premia and rising employment of skilled workers in the US and the UK since the 1980s. If more skilled workers demand more skill-intensive goods, then an increase in relative skill supply will also induce...

There is a widespread belief that a lack of education is the primary cause of public apathy to climate change. Yet, despite the global campaign to promote education as a tool to combat global warming, empirical evidence on the causal effect of education on climate literacy and pro-environmental...

The literature has pointed to different causes to explain the productivity gap between Europe and United States in the last decades. This paper tests the hypothesis that the lower European productivity performance in comparison with the US can be explained not only by a lower level of corporate...

This paper tests the differential effects of the generosity of the welfare state under free migration and under policy-controlled migration, distinguishing between source developing and developed countries. We utilize free-movement within the EU to examine the free migration regime and compare...
