We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and...

The IT, the Internet, or the Computing & Communications (C&C) technology revolution has been central to the economic discussion for several decades. Before the mid-1990s the catchword was the “productivity paradox” coined by Robert Solow, who stated in 1987 that “computers are everywhere...

In this paper we consider a simple model of horizontal differentiation and derive the closed form solutions for the level of the variables in the decentralized economy and in the social planner case. This enables us to analyze consumers’ welfare as a function of the parameter representing...

This paper provides new evidence on the relationship between innovation, competition and distance to the technology frontier, using enterprise surveys from 40 developing and transition countries. Different from previous empirical studies, the distance to frontier is measured by a firm's...

One of the important characteristics of Web2.0 is the collaboration between Web2.0 service providers. They allow users (i.e., providers, developers, consumers) to combine their services. The prerequisite for this collaboration is openness of the Web2.0 service system. Although the Web2.0...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

This paper builds a dynamic stochastic general equilibrium (DSGE) model of endogenous growth that is capable of generating substantial degrees of endogenous persistence in productivity. When products go out of patent protection, the rush of entry into their production destroys incentives for...

Although the structural reforms, initiated in 1991, did not lead to any appreciable increase in either the efficiency or the export orientation of Indian manufacturing firms, unexpectedly, there has been a visible improvement in manufacturing design capabilities in certain segments, for...
