We examine the dynamics of ideas production and knowledge-productivity relationship in a panel of 19 OECD countries. A new data set of triadic patents is used. We rigorously address the issues of cross-country heterogeneity and endogeneity. Domestic and foreign ideas stocks exert positive but...

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

We examine the dynamics of knowledge production for a panel of 19 OECD countries. A new and unique data set is used to proxy the domestic flows of “new-to-the-world” knowledge and ideas. We rigorously address the cross-country heterogeneity in the production of knowledge and the endogeneous...

Innovation depends on exporting and, in particular, on scale and competition in export markets. We develop a theory featuring (1) quality-segmented markets, (2) step-by-step innovation that moves firms forward along the quality ladder, and (3) escape-the-competition motives for innovation. We...

There has been a growing concern of developing industrial clusters in developed nations and emerging economies in the past two decades to strengthen economic growth and development. The concept of properly organised industrial clusters has not yet been heavily implemented in developing nations,...

This paper studies the effect of competition on firm innovation by developing a discrete-time endogenous growth model where multi-product firms do two types of innovation subject to friction in technology spillovers. Firms improve their existing products through internal innovation while...

We quantify the contribution of the largest firms to South Korea's economic performance over the period 1972-2011. Using firm-level historical data, we document a novel fact: firm concentration rose substantially during the growth miracle period. To understand whether rising concentration...
