We revisit a quality-then-pricing duopoly game, theoretically and experimentally exploring how heterogeneity in consumers' preferences affects firms' decisions and profits. We find that firms differentiate less their products in the lab than the theoretical model predicts, especially when the heterogeneity in consumers' preferences is high. When this heterogeneity is small, the firm producing the low-quality good profits more than the rival in the lab, which contradicts the theoretical predictions. [ABSTRACT FROM AUTHOR]

Most quality‐then‐price decision models under vertical product differentiation consider a predetermined market configuration. We endogenize market configuration considering quality‐dependent marginal costs and conclude that a strictly interior full coverage duopoly holds for some parameter values, unveiling the relevance of this commonly assumed market structure. Moreover, we show that a monopoly never arises in equilibrium, and (i) there are multiple equilibria at the frontier between interior and corner full coverage duopoly, (ii) the market is fully (partially) covered when relative tastes' heterogeneity is low (high), and (iii) there is a discontinuity in the transition from partial coverage to full coverage duopoly.

As consensus grows for low-carbon development, innovation becomes vital for green growth, given the substantial technology adoption needed for long-term environmental targets. This paper explores market-driven incentives for green product innovation in an asymmetric duopoly using a game theory approach without relying on direct government intervention. The roles that market dynamics and rivalry have on the supply of green or brown products are explored in simultaneous and sequential scenarios, considering technology costs, demand-creating effects, rivalry gains, and information availability. Results reveal that a fully green market is contingent on low innovation costs, depending especially on the magnitude of demand creation effects. Notably, product differentiation occurs only under extreme cost asymmetry. Recommendations underscore the importance of incentivising low-cost innovations, assessing the impact of product differentiation and diversity, especially concerning lower-income consumers, and proposing measures to improve the transparency of firms' strategic choices.

This paper addresses the impact of horizontal mergers on innovation, in an industry with a generic number of low‐cost and high‐cost competitors who first decide their level of process innovation and then compete in quantities in the product market. We derive the Nash equilibrium expressions for this game as a function of all the parameters involved, including number of players of each type, production costs, cost reductions achieved, and associated process innovation costs. Model results and parameter dependency are then illustrated in with a simulation of horizontal merger effects. [ABSTRACT FROM AUTHOR]

This paper examines the single and the joint influence of environmental policy stringency and oil prices on green innovation, admitting the possibility of different magnitudes of the response of innovation depending upon whether oil prices are increasing or decreasing, and accounting for endogeneity of policies. A panel data set of OECD countries is used over the period 1990–2016. Results suggest that increasing the stringency of environmental regulation can, beyond inducing green innovation, shield the effect of oil prices on innovation. In addition, a more stringent environmental policy reduces the asymmetric response of innovation when oil price increases or decreases. Thus, environmental policy and oil prices can be complements when inducing green innovation. Exploiting these complementarities requires an interdependent use of environmental and energy policies, through dynamic adjustments of subsidies and taxes on oil prices alongside reasonable levels of stringency in environmental policy.
