We study the impact of local competition on assortments' attractiveness. The first aim of our paper is to provide a simple and reproducible way to delineate a store trading area using widely available census data. The second aim is to develop a model of retail sales that takes into account competition intensity as well as assortment composition factors (namely price level and variety). We use s...

We study interfirm competition on a product market where effort decisions are delegated to the firms’ workers. Intrafirm organization is captured by a principal-multiagent framework where firm owners implement alternative compensation schemes for the workers.

We analyze the impact of these choices onmarket outcomes in oligopolistic industries. Our results highlight howdifferent contractual agreements change the intensity of price competition in service industries...

Questions: What factors influence tree species diversity of mangrove forests, an example of species-poor systems? What are the respective importance and interactions of these factors? Is the intermediate disturbance hypothesis applicable to such systems? Methods: We used the spatially explicit individual-based model KiWi to investigate the effects on species diversity of perturbation frequency ...

This paper empirically examines the effect of market competition – measured either by the Herfindahl Index or the Lerner Index – on productivity growth and R&D intensity using micro data for Japan’s manufacturing sector. We found evidence of an inverted U-shaped relationship between competition and innovation when we use the Herfindahl Index as a measure of competition in the market. In additio...

We find that hospital competition may increase both quantity and quality of hospital care, and if this is the case prospective payment has an unambigious positive effect on both quantity and quality. Hospitals may produce too little or ...
