全支付寡头垄断:不可观测库存选择下的价格竞争

All-Pay Oligopolies: Price Competition with Unobservable Inventory Choices
Review of Economic Studies · 2020 · João Montez、Nicolas Schutz

中文摘要

我们研究预先生产的情形,其中企业首先采购对竞争对手不可观测的库存,然后同时设定价格。在唯一的均衡中,每个企业偶尔会相对于其参考价格进行打折,导致企业有时会留有未售出的库存。在库存成本变得完全可收回的极限下,该均衡收敛至企业仅选择价格并按订单生产的博弈的均衡——即相关的伯川德博弈(其例子包括完全非对称的清算所模型)。因此,远离该极限时,我们的研究将伯川德型均衡推广至预先生产,并挑战了将预先生产与古诺结果相关联的普遍观点。作为中间步骤,该分析将价格-库存博弈映射为一个具有外部选项以及非单调赢和输函数的非对称全支付竞赛。我们将该框架应用于有关信息共享、并购、卡特尔和税收的公共政策。

Abstract

Abstract We study production in advance in a setting where firms first source inventories that remain unobservable to rivals, and then simultaneously set prices. In the unique equilibrium, each firm occasionally holds a sale relative to its reference price, resulting in firms sometimes being left with unsold inventory. In the limit as inventory costs become fully recoverable, the equilibrium converges to an equilibrium of the game where firms only choose prices and produce to order—the associated Bertrand game (examples of which include fully asymmetric clearinghouse models). Thus, away from that limit, our work generalizes Bertrand-type equilibria to production in advance, and challenges the commonly held view associating production in advance with Cournot outcomes. The analysis involves, as an intermediate step, mapping the price-inventory game into an asymmetric all-pay contest with outside options and non-monotonic winning and losing functions. We apply our framework to public policy towards information sharing, mergers, cartels, and taxation.
