摘要：This paper tests whether home bias exists among information producers. We find that credit analysts are more generous when rating issuers from their home states compared with (a) benchmark analysts from outside the state and (b) their own standards for rating issuers from other states. This home analyst effect strengthens around key rating certifications (AAA and investment grade), reduces credit spreads, and expands affected issuers' debt capacity. We conduct several tests to address the poss...

摘要：We draw on the skewness literature to propose regression-based performance evaluation tests designed for investments with option-like returns. These tests deliver conclusions valid for all risk-averse mean-variance-skewness investors and can better account for nonlinearities in returns than option-based factor models. Applied to mutual and hedge funds, our tests usually suggest selecting different funds than standard tests and find that a significant fraction (11%) of hedge funds adds value to...

摘要：In this article, we examine whether consumers may accidentally endanger a product they own when a new version of the product is introduced. We propose that owners endanger their product when they want to upgrade to a new version but have difficulty justifying the upgrade and that owners find justification more difficult when a new version offers an improved design but does not offer a significant technological improvement. Owners endanger their product hoping that it will be fortuitously damag...

摘要：We consider the problem of A-B testing when the impact of the treatment is marred by a large number of covariates. Randomization can be highly inefficient in such settings, and thus we consider the problem of optimally allocating test subjects to either treatment with a view to maximizing the precision of our estimate of the treatment effect. Our main contribution is a tractable algorithm for this problem in the online setting, where subjects arrive, and must be assigned, sequentially, with co...

摘要：Using proprietary survey data of investor relations (IR) officers from 59 countries, we uncover new stylized facts on a wide variety of IR functions, such as the firm's interactions with brokers and investors, the formulation of its disclosure policies, and its global outreach efforts. We find that IR activities vary widely across firms, industries, and countries. They have become increasingly important, as reflected by the more frequent involvement of IR officers with senior executives on a d...

摘要：Blockchain-based platforms often rely on token-weighted voting (t-weighting) to efficiently crowdsource information from their users for a wide range of applications, including content curation and on-chain governance. We examine the effectiveness of such decentralized platforms for harnessing the wisdom and effort of the crowd. We find that t-weighting generally discourages truthful voting and erodes the platform's predictive power unless users are strategic enough to unravel the underlying a...

摘要：Many products have similar or common attributes and are thus correlated. We show that, when these attributes are uncertain for consumers, a complementarity effect can arise among competing products in the sense that the lower price of one product may increase the demands for the others. This effect occurs when consumers sequentially search for information about both common and idiosyncratic product attributes before purchase. We characterize the optimal search strategy for the correlated searc...

摘要：We report from a large-scale randomized field experiment conducted on a unique sample of more than 15,000 taxpayers in Norway who were likely to have misreported their foreign income. By randomly manipulating a letter from the tax authorities, we cleanly identify that moral suasion and the perceived detection probability play a crucial role in shaping taxpayer behavior. The moral letter mainly works on the intensive margin, while the detection letter has a strong effect on the extensive margin...

摘要：We explore conditions under which a multiproduct firm can profitably turn itself into a platform by hosting rivals, that is, by inviting rivals to sell products or services on top of its core product. Hosting eliminates the additional shopping costs to consumers of buying a specialist rival's competing version of the multiproduct firm's noncore product. On the one hand, this makes it easier for the rival to compete on the noncore product. On the other hand, hosting turns the rival from a pure ...

摘要：A classical approach to collecting and elaborating information to make entrepreneurial decisions combines search heuristics, such as trial and error, effectuation, and confirmatory search. This paper develops a framework for exploring the implications of a more scientific approach to entrepreneurial decision making. The panel sample of our randomized control trial includes 116 Italian startups and 16 data points over a period of about one year. Both the treatment and control groups receive 10 ...
