This paper investigates the impact of technical progress on the relationship between competition an investment. Using a model of oligopoly competition with di¤erentiated products where firms invest to reduce their marginal cost of production, I find that technical progress, which increases the...

This paper analyzes how market power can be measured in an industry characterized by significant technological progress. Using a Cournot’s oligopolistic framework with exogenous innovation and costly investment in new technology, It shows that the Lerner index and the Herfindahl-Hirschman...

This paper investigates the impact of technical progress on the relationship between competition an investment. The competition is measured as the degree of substitutability and technical progress enlarges the size of innovation in cost reduction. In a context of duopoly, technical progress...

This paper addresses the empirical relationship between the level of competition and the rate of productivity growth across thirty sectors of the French production system during the period 1978-2015. It shows that there exists an optimal level of competition for each sector that is defined by...

The relationship between competition and investment is generally characterized by an inverted-U relationship. The position of these curves and, in particular their maximum, i.e, the degree of competition that maximizes investment, depends on the degree of technical progress that characterizes...

We show that the relationship between the level of competition (the price markup) and the growth of labor productivity in 28 sectors of a panel of 8 euro area countries between 1995 and 2018 is consistent with an inverted U-shaped curve. We calculate an optimal price markup that maximizes...

This paper investigates the relationship between technical progress, competition, and the impact on consumer's surplus and welfare. A Hotelling model in symmetrical duopoly with full market coverage is introduced. Firms invest in order to improve the quality of their offer and thus consumers'...

This paper investigates the impact of technical progress on the relationship between competition an investment. Using a model of oligopoly competition with differentiated products where firms invest to reduce their marginal cost of production, I find that technical progress, which increases the...
