摘要：The typical analysis on the effectiveness of soda taxes relies on price elasticity estimates from static demand models, which ignores consumers' inventory behaviors and their persistent tastes. This article provides estimates of the relevant price elasticities based on a dynamic demand model that better addresses potential intertemporal substitution and unobservable persistent heterogeneous tastes. It finds that static analyses overestimate the long-run own-price elasticity of regular soda by ...

摘要：We study the exclusionary properties of nonlinear price-quantity schedules in an Aghion-Bolton style model with elastic demand and product differentiation. We distinguish three regimes, depending on whether and how the price charged by the dominant firm depends on the quantity purchased from the rival firm. We find that the supply of rival good is distorted downward. Moreover, given the quantity supplied from the rival, the buyer may opportunistically purchase inefficiently many units from the...

摘要：From a theory viewpoint, the use of auctions with zero public reserve prices, also called absolute auctions, or of auctions with secret reserve prices, is somewhat puzzling despite being common. By allowing that buyers differ in their processing of past data regarding how the participation rate varies with the auction format and how reserve prices are distributed when secret, we show in a competitive environment that these auction formats may endogenously emerge. We also analyze how buyers wit...

摘要：This article considers investment decisions within an uncertain dynamic and duopolistic framework. Each investment decision involves to determine the timing and the capacity level. The simultaneous analysis of timing and capacity decisions extends work on entry deterrence/accommodation to consider a timing/delay element. We find that, when applying an entry deterrence policy, the first investor, or incumbent, overinvests in capacity for two reasons. First, it delays the investment of the secon...

摘要：This article analyzes the welfare effects of monopoly differential pricing in the important, but largely neglected, case where costs of service differ across consumer groups. Cost-based differential pricing is shown to increase total welfare and consumer welfare relative to uniform pricing for broad classes of demand functions, even when total output falls or the output allocation between consumers worsens. We discuss why cost-based differential pricing tends to be more beneficial for consumer...

摘要：We propose an extension of the Olley and Pakes () productivity decomposition that accounts for the contributions of surviving, entering, and exiting firms to aggregate productivity changes. We argue that the other decompositions that break down aggregate productivity changes into similar components introduce some biases in the measurement of the contributions of entry and exit. We apply our proposed decomposition to Slovenian manufacturing data and contrast our results with those of other deco...

摘要：Merger efficiencies provide the primary justification for why mergers of competitors may benefit consumers. Surprisingly, there is little evidence that efficiencies can offset incentives to raise prices following mergers. We estimate the effects of increased concentration and efficiencies on pricing by using panel scanner data and geographic variation in how the merger of the brewers Miller and Coors was expected to increase concentration and reduce costs. All else equal, the average predicted...

摘要：We offer a new explanation for why platforms, such as Internet service providers and mobile-phone networks, offer plans with download limits: through one of two mechanisms, doing so causes content providers to reduce prices or improve quality. This generates greater surplus for consumers, which a platform captures via higher consumer access fees. Even accounting for congestion externalities, a platform limits downloads more than would be welfare maximizing; indeed, by so much, that barring suc...

摘要：We investigate the feasibility of implementing an allocation rule with a gradual-revelation mechanism in which agents reveal their private information over time (rather than all at once). With independently distributed types, private values, and transferable utilities satisfying a single-crossing property, an ex-post monotonicity condition is sufficient for budget-balanced implementation of any incentive-compatible allocation rule with any gradual-revelation scheme. When we extend the single-c...
