Finance

Finance is a featured research topic at Harvard Business School.

Our intellectual roots are based in a long line of scholars from Robert Merton whose collaborative work on risk management and option pricing won him the Nobel Prize in Economics in 1997, to John Lintner who co-created the Capital Asset Pricing Model and made significant contributions to dividend policy, and Gordon Donaldson whose work helped shape the field of corporate finance. We strive to understand how managers and firms make value-enhancing decisions; and how financial institutions, markets, and instruments contribute to this process. Our approach to research is distinguished by its unique combination of theory, empirical analysis, mathematical modeling, and field observations at companies.

Macroeconomic Drivers of Bond and Equity Risks
John Y. Campbell, Carolin E. Pflueger and Luis M. Viceira
Our new model of consumption-based habit generates time-varying risk premia on bonds and stocks from loglinear, homoskedastic macroeconomic dynamics. Consumers' first-order condition for the real risk-free bond generates an exactly loglinear consumption Euler equation, commonly assumed in New Keynesian models. We estimate that the correlation between inflation and the output gap switched from negative to positive in 2001. Higher inflation lowers real bond returns, and higher output raises stock returns, explaining why the bond-stock return correlation changed from positive to negative. In the model, risk premia amplify this change in bond-stock return comovement and are crucial for a quantitative explanation.

Playing Favorites: How Firms Prevent the Revelation of Bad News
Lauren Cohen, Dong Lou and Christopher J. Malloy
We explore a subtle but important mechanism through which firms can control information flow to the markets. We find that firms that “cast” their conference calls by disproportionately calling on bullish analysts tend to underperform in the future. Firms that call on more favorable analysts experience more negative future earnings surprises and more future earnings restatements. A long-short portfolio that exploits this differential firm behavior earns abnormal returns of up to 149 basis points per month, or almost 18 percent per year. We find similar evidence in an international sample of earnings call transcripts from the UK, Canada, France, and Japan. Firms with higher discretionary accruals, firms that barely meet/exceed earnings expectations, and firms (and their executives) that are about to issue equity, sell shares, and exercise options, are all significantly more likely to cast their earnings calls.

Dynamics of Demand for Index Insurance: Evidence from a Long-Run Field Experiment
Shawn A. Cole, Daniel Stein and Jeremy Tobacman
This paper estimates how experimentally-manipulated experiences with a novel financial product, rainfall index insurance, affect subsequent insurance demand. Using a seven-year panel, we develop three main findings. First, recent experience matters for demand, consistent with overinference from small samples. Second, spillovers also matter, in the sense that the recent payout experience of village co-residents affects insurance demand about as much as one's own recent payout experience. Third, the spillover effect decays as time passes while the effect of one's own experience does not. We discuss implications of this analysis for commercial sustainability of this complicated but promising risk management technology.

Expectations of Returns and Expected Returns
Robin Greenwood and Andrei Shleifer
We analyze time-series of investor expectations of future stock market returns from six data sources between 1963 and 2011. The six measures of expectations are highly positively correlated with each other, as well as with past stock returns and with the level of the stock market. However, investor expectations are strongly negatively correlated with model-based expected returns. The evidence is not consistent with rational expectations representative investor models of returns.

Mortgage Convexity
Samuel G. Hanson
Most home mortgages in the United States are fixed-rate loans with an embedded prepayment option. When long-term rates decline, the effective duration of mortgage-backed securities (MBS) falls due to heightened refinancing expectations. I show that these changes in MBS duration function as large-scale shocks to the quantity of interest rate risk that must be borne by professional bond investors. I develop a simple model in which the risk tolerance of bond investors is limited in the short run, so these fluctuations in MBS duration generate significant variation in bond risk premia. Specifically, bond risk premia are high when aggregate MBS duration is high. The model offers an explanation for why long-term rates could appear to be excessively sensitive to movements in short rates and explains how changes in MBS duration act as a positive-feedback mechanism that amplifies interest rate volatility. I find strong support for these predictions in the time series of US government bond returns.

Financial Repression in the European Sovereign Debt Crisis
Bo Becker and Victoria Ivashina
By the end of 2013, the share of government debt held by the domestic banking sectors of Eurozone countries was more than twice its 2007 level. We show that this type of increasing reliance on the domestic banking sector for absorbing government bonds generates a crowding out of corporate lending. For a given domestic firm, new debt is less likely to be a loan—i.e., the loan supply contracts—when local banks have purchased more domestic sovereign debt and when that debt is risky (as measured by CDS spreads). These effects are most pronounced in the period following the second Greek bailout in early 2010.

Kaspi.kz IPO
Victoria Ivashina and Esel Çekin
This case follows Kaspi.kz, a private equity (Baring Vostok) co-owned retail bank in Central Asia that evolved into a fintech, payments and e-commerce company. It provides insights into private equity financing, portfolio company management, and initial public offering practices. In particular, the case focuses on (i) the bank’s journey from a traditional bank that serviced only corporations to an online platform, and (ii) the timing and process of preparation for an IPO. The management initially concentrated on profitability, but they soon shifted their emphasis to customer experience. The results were rewarding: Kaspi.kz became the number one player in online commerce, online payments, and consumer financing in Kazakhstan. The challenge of the IPO decisions is its timing: communicating the success of the fast transformation of the firm and its potential for further growth, especially in an emerging market like Kazakhstan, was far from trivial. From a business perspective, even a short delay of six months could potentially add millions of dollars to its value. Kaspi.kz’s private equity investor was interested in commencing a formal exit via an IPO, but the valuation was an important consideration. The case also provides a unique insight into financial fragility of the retail banking model, and how integration into an e-commerce platform interacts with the retail banking model.

Debt Redemption and Reserve Accumulation
Laura Alfaro and Fabio Kanczuk
In the past decade, foreign participation in local-currency bond markets in emerging countries increased dramatically. We revisit sovereign debt sustainability under the assumptions that countries can accumulate reserves and borrow internationally using their own currency. As opposed to traditional sovereign-debt models, asset-valuation effects occasioned by currency fluctuations act to absorb global shocks and render consumption smoother. Countries do not accumulate reserves to be depleted in “bad” times. Instead, issuing domestic debt while accumulating reserves acts as a hedge against external shocks. A quantitative exercise of the Brazilian economy suggests this strategy to be effective for smoothing consumption and reducing the occurrence of default.

Debt Traps? Market Vendors and Moneylender Debt in India and the Philippines
Dean Karlan, Sendhil Mullainathan and Benjamin Roth
A debt trap occurs when someone takes on a high-interest rate loan and is barely able to pay back the interest, and thus perpetually finds themselves in debt (often by refinancing). Studying such practices is important for understanding financial decision-making of households in dire circumstances as well as for setting appropriate consumer protection policies. We conduct a simple experiment in three sites in which we paid off high-interest moneylender debt of individuals. Most borrowers returned to debt within six weeks. One to two years after intervention, treatment individuals were borrowing at the same rate as control households.

Second Chance: Life Without Student Debt
Marco Di Maggio, Ankit Kalda and Vincent Yao
Rising student debt is considered one of the creeping threats of our time. This paper examines the effect of student debt relief on individual credit and labor market outcomes. We exploit the plausibly random debt discharge due to the inability of National Collegiate, the largest owner of private student loan debt, to prove chain of title for thousands of loans across the United States. Using hand-collected lawsuits filings matched with individual credit bureau information, we find that borrowers experiencing the debt relief shock reduce their indebtedness by 26%, by both reducing their demand for credit and limiting the use of existing credit accounts. They are also 12% less likely to default on other accounts. After the discharge, the borrowers' geographical mobility increases as well as their probability to change jobs. Ultimately their income increases by more than $4,000 over a three-year period, which is equivalent to about two months' average salary. These findings speak to the benefits of intervening in the student loan market to reduce the consequences of debt overhang problems by forgiving student debts.

It is Easy to be Brave From a Safe Distance: Proximity to the SEC and Insider Trading
Trung Nguyen and Quoc H. Nguyen
We use hand-collected data from SEC’s litigation releases for insider trading violations to examine the effect of geographic distance on its enforcement activities and insider trading activities. First, we find that the SEC is more likely to investigate companies that are closer to its offices. Second, we find that illegal insider trading increases with a company’s distance from an SEC office. Lastly, we utilize the closure of SEC offices as exogenous shocks to geographic proximity and find that insider trading at nearby companies increase significantly compared with trading at otherwise similar companies not affected by the closures.
