10/21/2023 — Customer review manipulation is a common strategy employed by sellers of online marketplaces to combat competitors. The impact of this deceptive behavior on the competitive pricing of online marketplaces is intricate. First, buying fake reviews incurs additional costs and alters customer demand in competitive settings by misrepresenting product information. Second, the pricing is determined through internal competitions, where sellers compete with each other within an online marketplace. This is because the winner's price is the default price displayed to customers, representing the price of the online marketplace. Meanwhile, online marketplaces also effectively manage prices in order to stay competitive in external competition against multi-channel retailers, further complicating this problem. To unravel this influence mechanism, we build instrumented econometric models and develop a game-theoretic model to empirically and theoretically analyze this influence mechanism in the context of internal and external competitions, respectively.

6/23/2023 — It is common wisdom that practice makes perfect. And, in fact, we find evidence that when given a choice between practicing a task and reflecting on their previously accumulated practice, most people opt for the former. We argue in this paper that this preference is misinformed. Using evidence gathered in ten experimental studies (N = 4,340) conducted across different environments, geographies, and populations, we provide a rich understanding of the conditions under which the marginal benefit of reflecting on previously accumulated experience is superior to the marginal benefit of accumulating additional experience.
