We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both...

The analysis of new product introduction using discrete-choice demand models has focused on successful products (e.g. the minivan) and their welfare impacts. Instead, we apply this approach to unsuccessful products to provide insight into the reasons for their failure. Our case study is the...

This paper investigates the effect of domestic market size on innovation activities across different durable good industries in the Chinese manufacturing sector. We address the endogeneity of market size by an IV strategy, based on a measure of potential market size, which is driven only by...

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 analyze the implications of entrepreneurial spawning for a variety of firm characteristics such as size, focus, profitability, and innovativeness. We examine the dynamics of spawning over time. Our model accounts for much of the empirical evidence relating to the relation between spawning and...

We analyze the implications of the decision to spawn or to retain a new product for the nature and evolution of the firm. In our model, a new product is spawned if the fit between the product and its parent firm organization is not adequate. We focus on the impact of the firm's history of...

The recent surge of patent disputes plays an important role in discouraging firms from entering new technology domains (TDs). Using a large-scale dataset combining data from the EPO-PATSTAT database and ORBIS-IP and containing patents applied at EPO between 2000 and 2015, we construct a new...

There is substantial heterogeneity across industries in the level of interdependence between new and old technologies. I propose a measure of this interdependence—an index of sequentiality in innovation—which is the transfer rate of patents in a particular industry. I find that...

High neo-natal mortality is one of the most salient 'facts' about firm performance in the industrial organization literature. We model firm survival and examine the relative influence of firm, industry and macroeconomic factors on survival for new vis-à-vis incumbent firms. In particular, we...
