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...

This paper presents a model of investment in a duopoly with firms that choose the scale and timing of investment. Decision-making flexibility and the costs saved by investing in large steps rather than sequences of small steps determine an incumbent's ability to deter entry by a potential...

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 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 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'...

During the second half of the twentieth century economic theory moved increasingly away from price theory, which was gradually displaced by more modern trends such as game theory, decision theory, behavioral-empirical-experimental economics, heterodox economics, etc. This was due to serious...

Do firms respond to cost shocks by reducing the quality of their products? Using microdata from a large Russian retailer that refreshes its product line twice-yearly, we document that higher quality products are more profitable than lower quality ones, but that the number of high quality...

We present estimates of inventory models based on firm level panel data and investigate whether over-simplified specification of the production technology may account for the frequent failure to find technological incentives to smooth production in the context of the standard linear-quadratic...

This paper presents a tractable model of a firm that chooses both the scale and timing of its investment. The value-maximizing investment policy is lumpy, and sensitivity analysis shows that greater demand volatility is associated with the firm choosing to invest in larger increments, less...

We question a deep-ingrained doctrine in asset pricing: if an empirical characteristic-return relation is consistent with investor “rationality,” the relation must be “explained” by a risk factor model. The investment approach changes the big picture of asset pricing. Factors formed on...
