Sticky Expectations and the Profitability Anomaly

We propose a theory of the “profitability” anomaly. In our model, investors forecast future profits using a signal and sticky belief dynamics. In this model, past profits forecast future returns (the profitability anomaly). Using analyst forecast data, we measure expectation stickiness at the firm level and find strong support for three additional model predictions: (1) analysts are on average too pessimistic regarding the future profits of high‐profit firms, (2) the profitability anomaly is stronger for stocks that are followed by stickier analysts, and (3) the profitability anomaly is stronger for stocks with more persistent profits.     

Information Inertia

We show that aversion to risk and ambiguity leads to information inertia when investors process public news about assets. Optimal portfolios do not always depend on news that is worse than expected; hence, the equilibrium stock price does not reflect this bad news. This informational inefficiency is more severe when there is more risk and ambiguity but disappears when investors are risk‐neutral or the news is about idiosyncratic risk. Information inertia leads to news momentum (e.g., after earnings announcements) and is consistent with low household trading activity. An ambiguity premium helps explain the macro and earnings announcement premium.     

AN ANALYSIS OF INTERNATIONAL PRICE DIFFERENTIALS ON EBAY

Online auction sites like eBay provide ways to measure what consumers buy and how much they pay. Does this imply that consumers pay similar prices, irrespective of their location? Comparing prices for homogeneous, tradable goods in the euro area and the United Kingdom, we find that prices differ significantly. The differential is not related to countries' having different currencies. However, price dispersion—the variance of prices—does seem to be smaller if two countries share a common currency. Our results confirm the importance of national borders in explaining price differences and their magnitude is related to (not) sharing a common currency. (JEL E30, E31, E50, F40)     

Efficient Recapitalization

We analyze government interventions to recapitalize a banking sector that restricts lending to firms because of debt overhang. We find that the efficient recapitalization program injects capital against preferred stock plus warrants and conditions implementation on sufficient bank participation. Preferred stock plus warrants reduces opportunistic participation by banks that do not require recapitalization, although conditional implementation limits free riding by banks that benefit from lower credit risk because of other banks’ participation. Efficient recapitalization is profitable if the benefits of lower aggregate credit risk exceed the cost of implicit transfers to bank debt holders.     

A Model of Monetary Policy and Risk Premia

We develop a dynamic asset pricing model in which monetary policy affects the risk premium component of the cost of capital. Risk‐tolerant agents (banks) borrow from risk‐averse agents (i.e., take deposits) to fund levered investments. Leverage exposes banks to funding risk, which they insure by holding liquidity buffers. By changing the nominal rate the central bank influences the liquidity premium, and hence the cost of taking leverage. Lower nominal rates make liquidity cheaper and raise leverage, resulting in lower risk premia and higher asset prices, volatility, investment, and growth. We analyze forward guidance, a “Greenspan put,” and the yield curve.     

Bank Mergers, Competition, and Liquidity

We model the impact of bank mergers on loan competition, reserve holdings, and aggregate liquidity. A merger changes the distribution of liquidity shocks and creates an internal money market, leading to financial cost efficiencies and more precise estimates of liquidity needs. The merged banks may increase their reserve holdings through an internalization effect or decrease them because of a diversification effect. The merger also affects loan market competition, which in turn modifies the distribution of bank sizes and aggregate liquidity needs. Mergers among large banks tend to increase aggregate liquidity needs and thus the public provision of liquidity through monetary operations of the central bank.     

Morgenstern's Forgotten Contribution: A Stab to the Heart of Modern Economics

In contrast to physics, there is no estimate of statistical error within economics in spite of Oskar Morgenstern's book On the Accuracy of Economic Observation. The problem of error in economic observations is still a widely neglected problem. The various sources of error that come into play in the social sciences suggest that the error in economic observations is substantial. As the error might be substantial, this paper argues that the usefulness of econometrics becomes questionable.     

Who Borrows from the Lender of Last Resort?

We analyze lender of last resort (LOLR) lending during the European sovereign debt crisis. Using a novel data set on all central bank lending and collateral, we show that weakly capitalized banks took out more LOLR loans and used riskier collateral than strongly capitalized banks. We also find that weakly capitalized banks used LOLR loans to buy risky assets such as distressed sovereign debt. This resulted in a reallocation of risky assets from strongly to weakly capitalized banks. Our findings cannot be explained by classical LOLR theory. Rather, they point to risk taking by banks, both independently and with the encouragement of governments, and highlight the benefit of unifying LOLR lending and bank supervision.     

A Pyrrhic Victory? Bank Bailouts and Sovereign Credit Risk

We model a loop between sovereign and bank credit risk. A distressed financial sector induces government bailouts, whose cost increases sovereign credit risk. Increased sovereign credit risk in turn weakens the financial sector by eroding the value of its government guarantees and bond holdings. Using credit default swap (CDS) rates on European sovereigns and banks, we show that bailouts triggered the rise of sovereign credit risk in 2008. We document that post‐bailout changes in sovereign CDS explain changes in bank CDS even after controlling for aggregate and bank‐level determinants of credit spreads, confirming the sovereign‐bank loop.     

The WACC Fallacy: The Real Effects of Using a Unique Discount Rate

In this paper, we test whether firms properly adjust for risk in their capital budgeting decisions. If managers use a single discount rate within firms, we expect that conglomerates underinvest (overinvest) in relatively safe (risky) divisions. We measure division relative risk as the difference between the division's asset beta and a firm‐wide beta. We establish a robust and significant positive relationship between division‐level investment and division relative risk. Next, we measure the value loss due to this behavior in the context of acquisitions. When the bidder's beta is lower than that of the target, announcement returns are significantly lower.
