There is a need for a conceptual approach that, with reference to explicit micro-level mechanisms and processes of industrial dynamics, articulates the role and function of entrepreneurial experimentation in innovation systems. This paper develops the concept of "entrepreneurial systems of...

Inventors generally know more about their inventions than what is written down in patent applications. Because they possess this tacit knowledge, inventors may need to play an active role when patents are commercialized. We build on Arora (1995) and model firm-inventor cooperation in the...

We estimate the effect of college education on business survival using the NLSY79. The endogeneity of both education and business ownership is accounted for by a competing risks duration model augmented with a college selection equation. Contrary to the previous literature, we fi nd no effect of...

The objective of this paper is twofold. First, against the background of an existing empirical literature on the duration of trade which has found that international trade is often of strikingly short duration, we aim to establish whether or not EU imports from the rest of the world also are...

Aiming to explore how the survival of trade flows has evolved over time, we analyze a rich data set of detailed imports to individual EU15 countries from 140 non-EU exporters, covering the period 1962-2006. We find that short duration is a persistent characteristic of trade throughout the...

The recent literature on the duration of trade has predominantly analyzed the determinants of trade flow durations using Cox proportional hazards models. The purpose of this paper is to show why it is inappropriate to analyze the duration of trade with continuous-time models such as the Cox...

This paper studies how cognitive and social skills in childhood are related to the duration of unemployment in adolescence and early adulthood. I estimate a flexible proportional hazard rate model for the probability of making a transition from unemployment to employment during an individual's...

I investigate the effect of human capital on entrepreneurship using the National Longitudinal Survey of Youth - 1979. I find that individuals with higher measured intelligence and self-confidence are more likely to be entrepreneurs. Furthermore I present evidence suggesting that intelligence and...
