    Price and quality competition

    This study considers an oligopoly model with simultaneous price and quality choice. Exante homogeneous sellers compete by offering products at one of two quality levels. The consumers have heterogeneous tastes for quality: for some consumers it is efficient to buy a high quality product, while for others it is efficient to buy a low quality product. In the symmetric equilibrium �firms use mixed strategies that randomize both price and quality, and obtain strictly positive pro�ts. This framework highlights trade-offs which determine the impact of consumer protection policy in the form of quality standards

Copyright @ 2008 Elsevier B.V.I consider an oligopoly model where, prior to price competition, firms invest in persuasive advertising and induce brand loyalty in consumers who would otherwise buy the cheapest alternative on the market. This setting, in which persuasive advertising is introduced to homogeneous product markets, provides an alternative explanation for price dispersion phenomena. Despite ex ante symmetry, the equilibrium profile of advertising outlays is asymmetric. It follows that endogenously determined brand loyal consumer bases are not symmetric across firms. This raises a robustness question regarding Varian's “model of sales” where symmetry is exogenously assumed.IVI

    Loyalty discounts

    This paper considers the use of loyalty inducing discounts in vertical supply chains. An upstream manufacturer and a competitive fringe sell differentiated products to a retailer who has private information about the level of stochastic demand. We provide a comparison of market outcomes when the manufacturer uses two-part tariffs (2PT), all-unit quantity discounts (AU), and market share discounts (MS). We show that retailer's risk attitude affects manufacturer's preferences over these three pricing schemes. When the retailer is risk-neutral, it bears all the risk and all three schemes lead to the same outcome. When the retailer is risk-averse, 2PT performs the worst from manufacturer s perspective but it leads to the highest total surplus. For a wide range of parameter values (but not for all) the manufacturer prefers MS to AU. By limiting the retailer's product substitution possibilities MS makes the demand for manufacturer s product more inelastic. This reduces the amount (share of total profits) the manufacturer needs to leave to the retailer for the latter to participate in the scheme.This study is funded from the Valencian Economic Research Institute (IVIE) and the European Commission

    The Optimal Minimum Wage with Regulatory Uncertainty

    Get PDF
    For two di¤erent regulatory standards, we examine the optimal minimum wage in a competitive labour market when the government is uncertain about supply and demand. Solutions are related to underlying supply and demand conditions, and to the extent of uncertainty and of rationing e¢ ciency. With expected earnings-maximization, greater uncertainty widens the range of parameter values for which a minimum wage should be set. With expected worker surplus-maximization and su¢ ciently e¢ cient rationing, a minimum wage should always be set. However, in both cases regulatory uncertainty may require a low minimum wage that may not bind in equilibrium

    Pro-Consumer Price Ceilings under Regulatory Uncertainty

    Get PDF
    We examine optimal price ceilings when the regulator is uncertain about demand and supply conditions and maximizes expected consumer surplus. We consider both a perfectly competitive benchmark and imperfectly competitive settings where symmetric firms compete in supply functions. Our analysis indicates that regulatory uncertainty does not eliminate the scope for intervention with a price ceiling. Instead, sufficient uncertainty calls for softer intervention, with the price ceiling set at a relatively high level. We formalize the relationship between competitive pressure and the optimal price ceiling and show that, if uncertainty is great enough, the optimal price ceiling is increasing in the degree of competition, so that greater competitive pressure justifies less restrictive regulatory intervention. For the perfectly competitive case, we also explore how the optimal price ceiling is related to the level of rationing efficiency, pinning down a cut-off level of efficiency below which a price ceiling should not be used

    Consumer Privacy and Marketing Avoidance: A Static Model

    No full text
    We introduce the concept of marketing avoidance--consumer efforts to conceal themselves and to deflect marketing. The setting is one in which sellers market some item through solicitations to potential consumers, who differ in their benefit from the item and suffer harm from receiving solicitations. Concealment by one consumer induces sellers to shift solicitations to other consumers, whereas deflection does not. Solicitations cause two externalities: direct harm on consumers and the (indirect) cost of consumer concealment and deflection. We find that in markets where the marginal cost of solicitation is sufficiently low, efforts by low-benefit consumers to conceal themselves will increase the cost-effectiveness of solicitations and lead sellers to market more. However, concealment by high-benefit consumers leads sellers to market less. Furthermore, concealment by low-benefit consumers increases direct privacy harm, and consumer welfare is higher with deflection than concealment. Finally, it is optimal to impose a charge on solicitations.marketing avoidance, privacy, advertising, promotion, segmentation
