This paper presents an intuitive model of university-industry (hereafter, UI) research linkages (or collaborations), focusing on the sharing principle under uncertainty. The paper draws from an earlier more complicated dynamic control theory model, but it differs in that it brings into the...

In this paper, we present some striking facts learned from a random subsampling of the global database of retracted academic papers, which have not been reported before and not discussed in the recent (famous) paper in Science by Brainard and You (Science 2019, doi:10.1126/science.aav8384). Our...

Although there exists a vast literature on convergence and divergence of income levels across countries or regions at the aggregate level, there is only little work on convergence and/or diver- gence processes of productivity and wage levels at the more disaggregated industrial level. These are...

Previous research on optimal R&D subsidies has focussed on the long run. This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R&D subsidization in...

While most countries have harmonized intellectual property rights (IPR) legislation, the dispute about the optimal level of IPR-enforcement remains. This paper develops an endogenous growth framework with two open economies satisfying the classical North-South assumptions to study (a)...

Fifty years ago, Punjab embarked on its famous Green Revolution, leading the rest of India in that innovation, and becoming the country's breadbasket. Now its economy and society are struggling by relative, and sometimes even absolute, measures. Using the original Green Revolution as a...

This study investigates whether capital-skill complementarity is the explanation for skill-biased technical change. For this to be the case, capital-skill complementarity must exist in the first place and, secondly, all technical change must be embodied in nature, i.e. embedded in new capital...

We show that the two-sector version of the AK model proposed by Rebelo (1991) can be read as an endogenous growth extension of Greenwood, Hercowitz and Krusell (1997). By confining constant returns to capital to the investment goods sector, the model generates endogenously the secular downward...

The fraction of women in economics has grown significantly over the last forty years. In spite of this, the differences in research output between men and women are large and persistent. These output differences are related to differences in the co-authorship networks of men and women: women...
