This paper analyses simultaneous regulation of cost and quality when firms have private, correlated information about productivity and the regulator receives a signal about quality. It is shown that managerial effort and expenditures on quality are positively correlated in the optimal contract....

The introduction of antibiotics as a medical treatment after World War II helped to dramatically increase life expectancy in the industrialized world. However, over-prescription of antibiotics during the last few decades has led to a sharp increase in multi-resistant bacteria, disarming once...

We study the effects of parallel trade in the pharmaceutical industry. We develop a model in which an original manufacturer competes in its home market with parallel-importing firms. The theoretical analysis results in two key hypotheses. First, if the potential for parallel imports is...

We consider policy issues regarding parallel imports (PIs) of brand-name pharmaceuticals in the European Union, where such trade is permitted. We develop a simple model in which an original manufacturer competes in its home market with PI firms. The model suggests that for small trade costs the...

The policy debate in recent years has increasingly focused on issues concerning size distribution of firms and employment. It is often claimed that we are approaching a new economic era where large enterprises have lost their importance in developed economies. This raises the question of what we...

Quantifying possible inefficiencies stemming from regulation is important to both policymakers and researchers. We use a dynamic structural model to evaluate the role of local market entry regulations in the productivity of retail trade. Our model is flexible with respect to how local market...

This paper examines the evolution of a skew distribution of firm sizes from the viewpoint of the 'Bounds' approach to market structure. It confines attention to the role played by non-strategic factors (statistical independence, and cost side effects). A model is proposed, which leads to a...
