We investigated the role of public funding in cardiovascular device innovation across 31 countries in Europe. We rely on the knowledge production function (KPF) framework that establishes the knowledge output of a region as a function of innovatory effort and other characteristics of that...

Several studies have focused attention on the differences between organic and conventional farms in terms of efficiency, and controversial findings have resulted from these applications. One source of controversy concerns the assumption about the frontier(s) adopted for the comparison: a common...

Agricultural inputs are peculiar in nature as an asymmetry in their roles can be identified during the production process. These inputs can be grouped into a set of growth inputs or a set of facilitating inputs. The inputs affecting biological or physiological growth from the inside of the plant...

We study a production network where quality choices are interconnected across firms. High-quality firms are skill intensive and trade more with other high-quality firms. Using data from Turkish firms, we document strong assortative matching of skills in the production network. A firm-specific...

Commonly used methods of production function estimation assume that a firm’s output quantity can be observed as data, but typical datasets contain only revenue, not output quantity. We examine the nonparametric identification of production function from revenue data when a firm faces a general...

This paper examines the long-run impact of ordinal rank during primary school on productivity using comprehensive English administrative data. Identification is obtained from variation in test score distributions across cohorts and subjects, such that the same score relative to the class mean...
