摘要:
This paper studies games of voluntary disclosure in which a sender discloses evidence to a receiver who then offers an allocation and transfers. We characterize the set of equilibrium payoffs in this setting. Our main result establishes that any payoff profile that can be achieved through information design can also be supported by an equilibrium of the disclosure game. Hence, our analysis suggests an equivalence between disclosure and design in these settings. We apply our results to monopoly pricing, bargaining over policies, and insurance markets.

摘要:
We assess whether unconventional monetary and fiscal policy implemented in response to the COVID-19 pandemic contribute to the 2021-2023 inflation surge through the lens of several different empirical methodologies—event studies, vector autoregressions, and regional panel regressions using granular data—and establish a null result. The key economic mechanism works through a disinflationary channel in the Phillips curve while monetary and fiscal stimuli put positive pressure on inflation through the usual demand channel. We illustrate this negative supply-side channel both theoretically and empirically.

摘要:
本文构建了可用于研究参与电商平台如何影响企业创新的理论模型,并在此基础上匹配了2002—2019年1688电商平台与中国专利数据库中高度细化的微观企业数据,实证检验了参与电商平台对制造业企业创新的影响效应和内在机制。本文主要的研究发现是:(1)参与电商平台将显著提升制造业企业的创新水平,该结果在经过倾向得分匹配、基于工具变量的内生性处理等一系列稳健性检验后依然显著成立。(2)影响机制分析表明:参与电商平台主要通过扩大市场规模和促进知识溢出两个渠道推动制造业企业创新。(3)基于创新网络的拓展性分析发现,参与电商平台还将显著提升制造业企业在创新网络中的专利中心度以及明星专利数。因此,本文研究为探索数字经济与实体经济深度融合的创新驱动路径提供了有益支撑。

摘要:
We study how firms adapt hedging policies to manage increased weather-related risks due to climate change. We introduce a parsimonious model of financial and operational hedging, and financing frictions. Financial hedging reduces the firm's exposure to weather risk, lowering the firm's subsequent incentive to hedge operationally. However, financial hedging also makes the firm's debt safer and reduces borrowing costs, mitigating the conventional debt overhang problem that typically discourages operational hedging investments. The two types of hedging policies are strategic complements when financing frictions are sufficiently severe; otherwise, they are substitutes. We test the model's predictions using the U.S. electric power industry as an empirical setting. We document a financial hedging overhang: firms that hedge via financial contracts subsequently engage in less operational hedging, such as maintaining gas inventories.
