Many street-level bureaucrats (such as caseworkers) have the dual task of helping some clients, while sanctioning others. We develop a model of such a street-level bureaucracy and study the implications of its personnel policy on the self-selection and allocation decisions of agents who differ...

This paper explores the meaning and implications of the desire by workers for impact. We find that this impact motive can make a firm in a competitive labor market face an upward-sloping supply curve of labor, lead workers with the same characteristics but at different firms to earn different...

Civil servants have a reputation for being lazy. However, people's personal experiences with civil servants frequently run counter to this stereotype. We develop a model of an economy in which workers differ in laziness and in public service motivation, and characterise optimal incentive...

To examine this question the Dutch economy is used as an exemplary case as the Netherlands are known as a nation of traders. This...</p></a>

This paper examines the consequences of creating a fully competitive market in a sector previously dominated by a cost-minimizing public firm. Workers in the economy are heterogeneous in their intrinsic motivation to work in the sector. In line with empirical findings, our model implies that...

More than a decade ago Oswald has formulated the thesis that homeownership increases unemployment. Empirical research on micro data has confirmed that unemployed homeowners are less inclined to move house in combination with accepting a new job elsewhere. However, in general for European...

This paper examines the empirical analysis of treatment effects on duration outcomes from data that contain instrumental variation. We focus on social experiments in which an intention to treat is randomized and compliance may be imperfect. We distinguish between cases where the treatment starts...

We relate our empirical analyses to the theoretical model of Gibbons and Waldman (1999). In the...</p></a>

The U.S. unemployment rate has remained stubbornly high since the 2007-2009 recessionleading many to conclude that structural, rather than cyclical, factors are to blame. Relying on astandard job search and matching framework and empirical evidence from a wide array of labormarket indicators, we...

We develop and empirically test a labor market model with Public Employment Agencies (PEA) in order to understand why not all vacancies use the costless services provided by the PEA. We show that both the search market and the PEA can be active in equilibrium. In such an equilibrium, workers...
