We study the effects of broadband internet use on the investment decisions of individual investors. A public program in Norway provides plausibly exogenous variation in internet use. Our instrumental variables estimates show that internet use causes a substantial increase in stock market participation, driven primarily by increased fund ownership. Existing investors tilt their portfolios toward funds, thereby obtaining more diversified portfolios and higher Sharpe ratios, and do not increase their trading activity in stocks. Overall, access to high‐speed internet spurs a “democratization of finance,” with individuals making investment decisions that are more in line with the advice from portfolio theory.

Offering a comprehensive exploration of the revolutionary developments occuring in the world's financial markets and institutions, this edition looks at innovation, globalization and deregulation - with a focus on the actual practices of financial institutions, investors and financial instruments.

The proliferation of big data makes it possible to better target city services like hygiene inspections, but city governments rarely have the in-house talent needed for developing prediction algorithms. Cities could hire consultants, but a cheaper alternative is to crowdsource competence by making data public and offering a reward for the best algorithm. A simple model suggests that open tournaments dominate consulting contracts when cities can tolerate risk and when there is enough labor with low opportunity costs. We also report on an inexpensive Boston-based restaurant tournament, which yielded algorithms that proved reasonably accurate when tested “out-of-sample” on hygiene inspections.

The federal tax code provides preferential treatment for the production and use of renewable energy. We report estimates of the subsidies' effects on greenhouse gases (GHG) emissions developed in a recent National Research Council (NRC) Report. Due to lack of estimates of the impact of tax provisions on GHG emissions, new modeling studies were commissioned. The studies found, at best, a small impact of subsidies in reducing GHG emissions; in some cases, emissions increased. The NRC report also identified the need to capture the complex interactions among subsidies, pre-existing regulations, and commodity markets.

We examine the role of investor relations (IR) in private debt markets. We find that firms with dedicated IR officers (IROs) receive significantly lower loan spreads, particularly when lenders require a better understanding of the borrower’s risk profile. Among firms with IROs, those with longer tenured officers experience lower spreads, especially when IROs also manage financial responsibilities. To address endogeneity concerns, we demonstrate that loan spreads decline when a firm establishes an IR program and rise when the program is discontinued. Furthermore, when a different individual assumes the IRO role, loan spreads increase, even though there are no reductions in firm disclosure. Loans issued to firms with IROs also have shorter syndication duration, attract more nonrelationship, foreign, and nonbank participant lenders, feature more customized covenants, and are less likely to undergo renegotiation. Overall, our study provides robust evidence of the relevance of IR in private debt markets.

Creativity drives profit in an idea economy, and many companies organize teams to facilitate creativity. This paper investigates the strategic deployment of individuals to boost a team’s creativity. More individualistic team members tend to generate highly original ideas yet are less likely to share these ideas. We theorize that adding a connector—an individual strongly predisposed to form and foster relationships—to a team will enable more idea sharing among individualistic team members, thus increasing the likelihood that the team’s creative potential will be realized. We leverage a new conceptualization of the “connector” construct to identify connectors and then use an experiment to study the impact of their presence or absence on team creative performance. Our results support these predictions and suggest that connectors improve team creativity by enabling others to share in the creative process and not because connectors themselves exhibit greater creative performance than their average peer. Data Availability: The data reported in the paper are available from the authors.

Prior research finds that clients of high-quality auditors report higher-quality GAAP earnings. We extend this research to investigate whether auditor quality is associated with the quality of voluntarily disclosed non-GAAP earnings measures. Using a sample of Australian firms disclosing annual non-GAAP metrics, we find that clients of high-quality auditors are more likely to voluntarily disclose non-GAAP earnings numbers. However, clients of high-quality auditors make adjustments in calculating non-GAAP earnings (non-GAAP exclusions) that are less predictive of future earnings and less value relevant than those of other firms. These results indicate that their adjustments are of higher quality. We also find similar results for U.S. firms using a sample of quarterly non-GAAP earnings disclosures. Overall, our evidence indicates that commonly used indicators of audit quality for GAAP reporting are positively associated with the quality of voluntarily disclosed non-GAAP earnings measures.

The stylized fact that volatility is not priced in individual equity options does not withstand scrutiny. First, we show that the average return of heavily traded deep out‐of‐the‐money call options on stocks is −116 basis points per day. Second, Fama‐MacBeth estimates of the volatility risk premium in stock options are similar to those in S&P 500 Index call options. Third, the mean return of heavily traded delta‐hedged at‐the‐money calls (puts) is −23 (−30) basis points. Fourth, the variance risk premium in stock options is negative. Our analysis highlights the importance of microstructure biases and robustness in empirical work with options.

We empirically investigate one form of illegal investor‐level tax evasion and its effect on foreign portfolio investment. In particular, we examine a form of round‐tripping tax evasion in which U.S. individuals hide funds in entities located in offshore tax havens and then invest those funds in U.S. securities markets. Employing Becker's ( ) economic theory of crime, we identify the tax evasion component by examining how foreign portfolio investment varies with changes in the incentives to evade and the risks of detection. To our knowledge, this is the first empirical evidence of investor‐level tax evasion affecting cross‐border equity and debt investment.
