In recent decades, a large and increasing number of leading firms in a diverse set of industries have faced allegations of ‘unethical' practices along their international value chains. In many cases this has triggered consumer boycotts and NGO campaigns, introducing a new link between upstream...

The paper combines an economic-geography model of agglomeration and periphery with a model of species diversity and looks at optimal policies of biodiversity conservation. The subject of the paper is "natural" biodiversity, which is inevitably impaired by anthropogenic impact. Thus, the economic...

This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these margins respond to changes in average and marginal corporate tax rates. Intensive investment refers to the size of a firm’s capital stock. Extensive...

Papers on optimal harvesting regimes for maximizing land expectation value (LEV) that compare different logging practices often ignore differences in variable costs and in damages on the residual stand between logging practices. We use data on a multi-age, multi-species forest in East-Kalimantan...

There is a widespread consensus among the most important players in developed countries (voters, politicians, producers, traditional and green interest groups and bureaucracies) that a shift towards an eco-social market economy is essential for sustainable growth. Nevertheless, market-based...

Social interactions are considered pivotal to agglomeration economies. We explore a unique dataset on mobile phone calls to examine how distance and population density shape the structure of social interactions. Exploiting an exogenous change in travel times, we show that distance is highly...

We study the relationship between ethnicity, occupational choice, and entrepreneurship. Immigrant groups in the United States cluster in specific business sectors. For example, the concentration of Korean self-employment in dry cleaners is 34 times greater than other immigrant groups, and...
