We develop a dynamic general equilibrium model of imperfect competition where a sunk cost of creating a new product regulates the type of entry that dominates in the economy: new products or more competition in existing industries. Considering the process of product innovation is irreversible,...

This paper analyzes the effects of mergers and acquisitions on the markups of non-merging rival firms across a broad set of industries. We exploit expert market definitions from the European Commission's merger decisions to identify relevant competitors in narrowly defined product markets....

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 considers an international oligopoly where firms simultaneously choose both the amount of output produced and the proportion of R&D investment to output. The model captures the links between the exchange rate, market power, innovative activity and price, which are important for the...

This paper studies the introduction of new products (increase in product variety) in the automobile industry. The focus is on the two sources of market power that may allow the firms to get higher profits (and, thus, recoup investments): new products and brand-name reputation. The effects of new...

This article explores the possibility of associating firm size vis-à-vis industry size with firm-level R&D led-innovation and the resultant impact(s) on industry level output and price. We consider an oligopolistic industry having one dominant firm and some fringes. Innovation by the dominant...

By affecting prices and thereby market shares of green and brown firms, product innovations and process innovations influence industry emissions even when they do not directly affect the emission intensity of the innovating firm. Using a differentiated two-stage duopoly, this paper therefore...

This paper explores a panel data set matching establishment-based production statistics from Japan's Census of Manufacturers with wholesale price indices from the Bank of Japan, and Herfindahl indices from the Japan Fair Trade Commission. The data include annual observations over the period...
