Internet recommender systems are popular in contexts that include heterogeneous consumers and numerous products. In such contexts, product features that adequately describe all the products are often not readily available. Content-based systems therefore rely on user-generated content such as product reviews or textual product tags to make recommendations.
Shadow bank market share in residential mortgage origination nearly doubled from 2007 to 2015, with particularly dramatic growth among online "fintech" lenders. We study how two forces, regulatory differences and technological advantages, contributed to this growth.
We use a very accurate panel of all individual spending, income, balances, and credit limits from a financial aggregation app and document significant payday responses of spending to the arrival of both regular and irregular income. These payday responses are clean, robust, and homogeneous for all income and spending categories throughout the income distribution. Spending responses to income are typically explained by households' capital structures: households that hold little or no liquid wealth have to consume hand-to-mouth.
We study the intertemporal properties of accounting conservatism with a focus on managerial incentives. In our main model, conservatism results in smaller expected payouts to the manager (agent) in early periods and larger expected payouts in later periods. Conservatism shifts (ambiguous) evidence that might be used to recognize good performance in early periods to later periods. In later periods, good performance is less informative, since good news might mean good current period performance and might also mean good prior period performance whose recognition was delayed.
This paper studies how hedge fund activism impacts corporate innovation. Firms targeted by activists improve their innovation efficiency over the five-year period following hedge fund intervention. Despite a tightening in research and development (R&D) expenditures, target firms increase innovation output, as measured by both patent counts and citations, with stronger effects among firms with more diversified innovation portfolios. Reallocation of innovative resources, redeployment of human capital, and change to board-level expertise all contribute to improve target firms' innovation.
Firms often finance their inventory through debt and subsequently sell it to generate profits and service the debt. Pricing of products is consequently driven by both inventory and debt servicing considerations. In the present paper, we analyze how debt distorts dynamic pricing decisions and reduces generated sales revenues. We show that debt induces sellers to always price higher than the revenue-maximizing price.
We examine the Cochrane and Piazzesi (2005, 2008) model in several out-of-sample analyzes. The model's one-factor forecasting structure characterizes the term structures of additional currencies in samples ending in 2003. In post-2003 data one-factor structures again characterize each currency's term structure, but we reject equality of the coefficients across the two samples. We derive some implications of the model for the predictability of cross-currency investments, but we find little support for these predictions in either pre-2004 or post-2003 data.
We develop a theory of banking that explains why banks started out as commodities warehouses. We show that warehouses become banks because their superior storage technology allows them to enforce the repayment of loans most effectively. Further, interbank markets emerge endogenously to support this enforcement mechanism. Even though warehouses store deposits of real goods, they make loans by writing new "fake" warehouse receipts, rather than by taking deposits out of storage.
People can be surprisingly insensitive to quantities in valuation judgments—a phenomenon called scope insensitivity, which is generally attributed to the operation of affective processes in judgment. Building on research showing that affect is inherently a decision-making system of the present, we propose that scope insensitivity is more likely to be observed in decisions that are psychologically proximate to the immediate self.
