    Building on Vijh (Rev. Financial Stud. 7 (1994)), we use additions to the S&P 500 to distinguish two views of return comovement: the traditional view, which attributes it to comovement in news about fundamental value, and an alternative view, in which frictions or sentiment delink it from fundamentals. After inclusion, a stock’s beta with the S&P goes up. In bivariate regressions which control for the return of non-S&P stocks, the increase in S&P beta is even larger. These results are generally stronger in more recent data. Our findings cannot easily be explained by the fundamentals-based view and provide new evidence in support of the alternative friction- or sentiment-based view.

    Bordalo, Pedro, Nicola Gennaioli, and Andrei Shleifer. 2016. “Competition for Attention.” Review of Economic Studies 83 (2): 481-513. Abstract

    We present a model of market competition in which consumers' attention is drawn to the products' most salient attributes. Firms compete for consumer attention via their choices of quality and price. Strategic positioning of a product affects how all other products are perceived. With this attention externality, depending on the cost of producing quality some markets exhibit “commoditized” price salient equilibria, while others exhibit “de-commoditized” quality salient equilibria. When the costs of quality change, innovation can lead to radical shifts in markets, as in the case of decommoditization of the coffee market by Starbucks. In the context of financial innovation, the model generates the phenomenon of “reaching for yield”.

    In cooperation with Lex Mundi member law firms in 109 countries, we measure and describe the exact procedures used by litigants and courts to evict a tenant for nonpayment of rent and to collect a bounced check. We use these data to construct an index of procedural formalism of dispute resolution for each country. We find that such formalism is systematically greater in civil than in common law countries, and is associated with higher expected duration of judicial proceedings, less consistency, less honesty, less fairness in judicial decisions, and more corruption. These results suggest that legal transplantation may have led to an inefficiently high level of procedural formalism, particularly in developing countries.
