To reduce the chances of policy failures, policy makers need information about the effects of policies. Sometimes, policy makers can rely on agents who already possess the information. Often, the information has yet to be produced. This raises two problems. First, for a policy maker it is hard...

In many Western countries, a sizeable group of people live on welfare benefits for a long time. Many of them suffer from mental health issues. This paper studies the labor market and mental health effects of an activation program targeting these long-term inactive people. We exploit the...

A rich literature in public administration has shown that public sector employees have stronger altruistic motivations than private sector employees. Recent economic theories stress the importance of mission preferences, and predict that altruistic people sort into the public sector when they...

This paper develops a model in which workers to a certain extent enjoy working. We examine the implications of workers' intrinsic motivation for optimal monetary incentive schemes. We show that motivated workers work harder and, for a given level of e.ort, are willing to work for a lower wage....

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

We examine differences in altruism and laziness between public sector employees and private sector employees. Our theoretical model predicts that the likelihood of public sector employment increases with a worker's altruism, and increases or decreases with a worker's laziness depending on his...

In many public policy areas, randomized policy experiments can greatly contribute to our knowledge of the effects of policies and can thus help to improve public policy. However, policy experiments are not very common. This paper studies whether a lack of appreciation for policy experiments...

Civil servants have a bad reputation of being lazy. However, citizens' personal experiences with civil servants appear to be significantly better. We develop a model of an economy in which workers differ in laziness and in public service motivation, and characterise optimal incentive contracts...

A worker's utility may increase in his own income, but envy can make his utility decline with his employer's income. Such behavior may call for high-powered incentives, so that increased effort by the worker little increases the income of his employer. This paper uses a principalagent model to...

This paper offers a new argument for why a more aggressive enforcement of minor offenses ( zero-tolerance') may yield a double dividend in that it reduces both minor offenses and more severe crime. We develop a model of criminal subcultures in which people gain social status among their peers...
