I study the effect of the demolition of 22,000 units of public housing on crime in Chicago using an approach that is designed to capture general equilibrium spillovers. Point estimates that incorporate both the direct and spillover effect of the demolitions indicate that in the short run the...

We evaluate the impact of specially designed youth unemployment programmes (YUPs), intended to provide young unemployed unskilled workers with skills. If unemployment among skilled workers is lower than among unskilled workers, YUPs imply that unemployment falls. However, YUPs potentially crowd...

Many theories and public discussions about pension systems and their reforms are based on the assumption that individual age is a major factor in determining individual preferences for or against public pension schemes. The aim of this paper is to explore whether different age groups do indeed...

Most of the workers who earn at or below the minimum wage are either less educated, young, or female in the United States. In light of this, we examine the extent to which the minimum wage influences the wage differential among workers with different observed characteristics and the wage...

In this article, we consider identification, estimation, and inference procedures for treatment effect parameters using Difference-in-Differences (DID) with (i) multiple time periods, (ii) variation in treatment timing, and (iii) when the ``parallel trends assumption" holds potentially only...

Empirical evaluations of national minimum wages, such as in Germany or the UK, rely on bite measures that capture treatment variation; measured from the incidence (or intensity) of employees paid below the threshold before the minimum wage was introduced or raised. Bite-dependent estimations...

Recently the software industry has experienced fundamental changes in market structure through the entry of open source competitors, e.g. Linux‘s entry into the operating systems market. In a simple model we examine the effects of such a change in market structure from monopoly to duopoly...

We analyze the formation of environmental policy to regulate transboundary pollution if governments are self-interested. In a common agency framework, we portray the environmental policy calculus of two political supportmaximizing governments that are in a situation of strategic interaction with...

A theoretical model is adopted in order to explain incentives and actual safety behaviour for drivers, pedestrians and other road users which do not utilise motorised vehicles. A road user's outcome is supposed to be dependent on her individual actions and cares decided upon by other individuals...
