摘要：Combining forecasts is an established approach for improving forecast accuracy. So-called optimal weights (OWs) estimate combination weights by minimizing errors on past forecasts. Yet the most successful and common approach ignores all training data and assigns equal weights (EWs) to forecasts. We analyze this phenomenon by relating forecast combination to statistical learning theory, which decomposes forecast errors into three components: bias, variance, and irreducible error. In this framew...

摘要：How does market competition affect pay inequality between and within firms? Using division managers as a pool of similar workers and the Canada-U.S. Free Trade Agreement, we find that greater competition increases overall pay inequality between, but not within, firms. This null effect within firms is not driven by a lack of statistical power. Instead, we find that it arises primarily within subsamples of firms with higher predicted levels of social comparison. Increased competition leads to gr...

摘要：Consumers are often uncertain about their valuations for product quality when choosing among different products and will learn their valuations only after buying and using a product. Some consumers may thus experience overpurchase or underpurchase regret, depending on whether they have purchased a higheror lower-quality level than what they would have chosen had they known their true valuations. When consumers anticipate their potential postpurchase regret, their purchase decisions may be affe...

摘要：We develop a conceptually grounded approach, based on the International Accounting Standards Board's conceptual framework, to the accounting for the rights and obligations embodied in a cap-and-trade program. Under this approach, firms recognize allowances as intangible assets, initially measured at fair value with a credit to cash for purchased allowances and to a current period gain for allocated allowances; firms recognize current period expense and accrue liabilities, at fair value, as the...

摘要：We integrate the results of a social network survey and a forecast information sharing experiment to examine the roles of trust and trustworthiness in impacting highranking executives' decisions in supply chain interactions. The members of our executive sample have, on average, 17 years of work experience. A significant portion of them holds positions at the C-level in world-leading organizations that span a wide range of industries. By examining the roles of trust and trustworthiness in the d...

摘要：We explore marketplace design in the context of a business-to-business platform specializing in liquidation auctions. Even when the platform's aggregate levels of supply and demand remain fixed, we establish that the platform's ability to use its design levers to manage the availability of supply over time yields significant value. We study two such levers, each using the platform's availability of supply as a means to incentivize participation from buyers who decide strategically when/how oft...

摘要：Copy trading allows traders in social networks to receive information on the success of other agents in financial markets and to directly copy their trades. Internet platforms like eToro, ZuluTrade, and Tradeo have attracted millions of users in recent years. The present paper studies the implications of copy trading for the risk taking of investors. Implementing a novel experimental financial asset market, we show that providing information on the success of others leads to a significant incr...

摘要：This article investigates the effect of patent protection on the mobility of early career employee-inventors. Using data on patent applications filed at the U.S. Patent and Trademark Office between 2001 and 2012 and examiner leniency as a source of exogenous variation in patent protection, we find that one additional patent granted decreases the likelihood of changing employers, on average, by 23%. This decrease is stronger when the employee has fewer coinventors, works outside the core of the...

摘要：Based on a simulation, the authors of Newsvendor Demand Chasing Revisited recommended using correlation of orders with lagged demand to measure chasing behavior. They concluded that measuring chasing with regression based on partial adjustment is prone to false positives. We show the purported false positives are due to autocorrelation and recommend using partial adjustment regression-based approaches to evaluate chasing.

摘要：Current regulations on e-cigarettes are minimal compared with cigarette regulations, despite their growing popularity globally. Advocates of e-cigarettes claim that they aid in ceasing smoking habits. However, leaving e-cigarettes unregulated has raised growing health concerns. Policymakers in several countries, including the United States and those in Europe, are considering and experimenting with policy interventions. To evaluate current policies and implement potential regulations on e-ciga...
