This study explores multivariate methods for investment analysis based on a sample of return histories that differ in length across assets. The longer histories provide greater information about moments of returns, not only for the longer-history assets, but for the shorter-history assets as...

The headline numbers appear to show that even as banks and financial intermediaries suffered large credit losses in the financial crisis of 2007-09, they raised substantial amounts of new capital, both from private investors and through government-funded capital injections. However, on closer...

Derivatives exposures across large financial institutions often contribute to - if not necessarily create - systemic risk. Current reporting standards for derivatives exposures are nevertheless inadequate for assessing these systemic risk contributions. In this paper, I explain how a...

The global imbalance explanation of the financial crisis of 2007-09 suggests that demand for riskless assets from countries with current account surpluses created fragility in countries with current account deficits, most notably, in the United States. We examine this explanation by analyzing...

We analyze asset-backed commercial paper conduits which played a central role in the early phase of the financial crisis of 2007-09. We document that commercial banks set up conduits to securitize assets while insuring the newly securitized assets using credit guarantees. The credit guarantees...

What is the effect of financial crises and their resolution on banks' choice of liquid asset holdings? When risky assets have limited pledgeability and banks have relative expertise in employing risky assets, the market for these assets clears only at fire-sale prices following a large number of...

This study explores the role of investor sentiment in a broad set of anomalies in cross-sectional stock returns. We consider a setting where the presence of market-wide sentiment is combined with the argument that overpricing should be more prevalent than underpricing, due to short-sale...

A plot of expected returns versus betas obeys virtually no relation to an inefficient index portfolio's mean-variance location. If the index portfolio is inefficient, then the coefficients and R- squared from an ordinary-least-squares regression of expected returns on betas can equal essentially...

A representative-agent model with time-varying moments of consumption growth is used to analyze implications about means and volatilities of asset returns as well as the predictability of asset returns for various investment horizons. A comparative-statics analysis using non-expected-utility...
