In this paper, we endogenize the timing of policymaking in a simple two-country model of strategic environmental policy. We consider a timing game in which two policymakers non-cooperatively decide their preferred sequence of moves before setting emission tax rates. We show that whether the...

In this paper, we build a model of strategic misleading advertising in duopolistic markets with horizontal product differentiation and advertising externality between firms. We investigate the effects of regulating misinformation on market competition, behavior of firms, and social welfare. We...

This paper presents a duopoly model of firm rivalry in a vertically differentiated industry when market dynamics is explicitly accounted for. It shows how the interplay between demand (degree of product differentiation, demand elasticity) and cost (fixed and quality costs) factors determine...

A `collusion puzzle' exists by which, even though increasing the number of firms reduces the ability to tacitly collude, and leads to a collapse in collusion in experimental markets with four or more firms, in natural markets there are such numbers of firms colluding successfully. We present an...

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms' fixed costs...

This paper analyzes the impact of product market competition on unemployment, wage and welfare in a model where unemployment is caused by the efficiency wage consideration and oligopolistic firms compete in quantity. It is shown that while more intense competition in the product market increases...

This paper considers the effects of labels in a vertically differentiated duopoly. A label certifies the level of a product's measurable characteristic. It is shown that the certification label chosen by a private (for profit) certifier is lower than both the socially optimal and the firm's...

En este trabajo se muestran condiciones para la unicidad del equilibrio de Nash-Cournot para un juego de n-firmas. Estas condiciones garantizan que las funciones de mejor respuesta para n-firmas que compiten en forma oligopolica a la Cournot sean contracciones y generalizan las condiciones de...

We study the strategic disclosure of demand information and product-market strategies of duopolists. In a setting where firms may fail to receive information, we show that firms selectively disclose information in equilibrium in order to influence their competitor’s product-market strategy....

We investigate a linear state dfferential game describing an asymmetric Cournot duopoly with capacity accumulation à la Ramsey and a negative environmental externality (pollution), in which one of the firms has adopted corporate social responsibility (CSR) in its statute, and therefore includes...
