This paper studies how social relationships between managers and employees affect relational incentive contracts. To this end we develop a simple dynamic principal-agent model where both players may have feelings of altruism or spite toward each other. The contract may contain two types of...

The impacts of introducing or tightening time limits on welfare use are studied in an efficiency wage model. Those losing access to regular benefits receive some smaller benefit, which can be interpreted as food stamps. Stricter time limits raise both employment and profits and generally reduce...

This paper considers the optimal level of firm-specific training by taking into account the positive effect of training on the expected duration of workers’ current employment. In the framework of an efficiency wage model, a short expected job tenure represents a disamenity that reduces the...

Redundancy payments for collective dismissals are incorporated into a Shapiro-Stiglitz model of efficiency wages. It is shown that a fixed payment will lower wages, leave employment and welfare unaffected if there are no wage-dependent taxes, no additional firing costs and if unemployment...

In this paper we construct a stylised general equilibrium macromodel to show that demand led expansions may have unexpected effects when market imperfections lead to changes in labour productivity. We find some empirical support, from a number of European countries, for the main predictions of...

The impact of a stronger work requirement for welfare recipients in a workfare program is studied in an efficiency wage model where a representative firm chooses its level of monitoring activities. A stricter workfare policy raises employment and monitoring activities. It typically increases...

In this paper fiscal policy is examined for an open economy characterised by unemployment due to efficiency wages. We allow for capital and firm mobility in a model where the government chooses the level of wage, source-based capital and profit taxation. The taxing choices of governments are...

More progressive income taxes raise employment in models of imperfectly competitive labour markets. However, this prediction is not robust to modifications of the analytical structure. For example, in an efficiency wage setting, more progressive taxes reduce profits. This induces firms to exit...

The impacts of introducing work requirements for welfare recipients are studied in an efficiency wage model. If the workfare package is not mandatory, it will reduce employment, profits, and utility levels of employed and unemployed workers. In contrast, mandatory effort requirements will...

We study an important mechanism underlying employee referrals into informal low skilled jobs in developing countries. Employers can exploit social preferences between employee referees and potential workers to improve discipline. The profitability of using referrals increases with referee stakes...
