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.

In this work, we theoretically approach optimal taxing in a public good provision context in a society where wealth is Pareto distributed. Our main result shows that high levels of wealth inequality yield lower levels of tax compliance and, consequently, lower provision of public goods. [ABSTRACT FROM AUTHOR]
