The Journal of Economic Literature codes classification system (JEL) published by the American Association (AEA) is de facto standard for research literature in economics. JEL used to classify articles, dissertations, books, book reviews, and working papers EconLit, a database maintained AEA. Over time, it has evolved extended with over 850 subclasses.

We examine variation in the concentration of inventive activity across 72 of North America’s most highly innovative locations. In 12 of these areas, innovation is particularly concentrated in a single, large firm; we refer to such locations as “company towns.” We find that inventors employed by large firms in these locations tend to draw disproportionately from their firm’s own prior inventions...

Reductions in transport and transaction costs are expected to have a major effect on the functioning of food markets in developing countries. For many developing countries, this is a relevant issue as it may have important consequences for the food markets in urban and rural deficit areas. A partial equilibrium model is presented to analyze the effects of reduced costs on cereal price formation...

We construct a general equilibrium model of urban unemployment with a continuum of heterogeneous urban firms producing differentiated products in a monopolistic competitive market. We show that an increase in urban institutionally fixed minimum wage reduces urban aggregate output and each urban firm will experience an output cut proportional to the change in aggregate output. However, such prop...

Talent finding in sports can not only lead to winning teams but also ensure individuals continue to participate, improve their talents, and take preventive measures against injuries. Athletic talent often develops as the result of morphological, physiological, or psychological characteristics. Many of these characteristics are inherited, and genetics have important implications for talent. Tale...

The main conclusion is that the Romanian SME sector can represent an impor...

We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region. Different measures and estimation approaches lead to rather similar assessments. We find that both spillove...
