This paper aims to solve two fundamental problems on finite or infinite horizon dynamic games with complete information. Under some mild conditions, we prove the existence of subgame-perfect equilibria and the upper hemicontinuity of equilibrium payoffs in general dynamic games with simultaneous...

This paper offers a resolution to an extensively studied question in theoretical economics: which measure spaces are suitable for modeling many economic agents? We propose the condition of “nowhere equivalence” to characterize those measure spaces that can be effectively used to model the...

Recent studies have proposed a large set of powerful anomaly-based factors in the stock market.This study examines the role of investor inattention in the corresponding anomalies underlying these factors and other underreaction-related anomalies. Using media coverage as a proxy for investor...

We find that the degree of extrapolative weighting in investors' belief (DOX) proposed by Cassella and Gulen (2018) has strong predictive power for a broad set of overreaction-related anomalies in the stock market. The average return spread of these anomalies is about 0.81% per month following...

Similarity between two stocks is measured by the distance between their characteristics such as price, size, book-to-market, return on assets, and investment-to-assets. We find that after a stock's most similar stocks have experienced high (low) returns in the past month, this focal stock tends...

Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and at a lower...

Photovoltaic (PV) semiconductor degrades in performance due to temperature rise. A super thin-conductive thermal absorber is therefore developed to regulate the PV working temperature by retrofitting the existing PV panel into the photovoltaic/thermal (PV/T) panel. This article presented the...

We define and investigate a property of mechanisms that we call "strategic simplicity", and that is meant to capture the idea that, in strategically simple mechanisms, strategic choices are easy. We define a mechanism to be strategically simple if strategic choices can be based on first-order...

We study a robust version of the single-unit auction problem. The auctioneer has confidence in her estimate of the marginal distribution of a generic bidder's valuation, but does not have reliable information about the joint distribution. In this setting, we analyze the performance of...
