The financial crisis of 2007–2008 was the most serious since the Great Depression and severely impacted the global economy. Yet more than 10 years after the crisis, we still lack clear understanding of its cause. Accounts point to some elements of fact but tend to be fragmented and sometimes contradictory. More than ever, we need an account that can put the puzzle pieces together and help us understand how to prevent a crisis like this from happening again.

The crash of some of the flagbearers of the equity bubble in recent years has been painful for investors. We have seen “pandemic winner” Netflix dive 75 per cent from 2021 peaks, crypto exchange operator Coinbase plunge 86 per cent and the one-time meme stock and cinema chain AMC lose 80 per cent.

We use supervisory loan-level data to document that small firms (SMEs) obtain shorter maturity credit lines than large firms, post more collateral, have higher utilization rates, and pay higher spreads. We rationalize these facts as the equilibrium outcome of a trade-off between lender commitment and discretion. Using the COVID recession, we test the prediction that SMEs are subject to greater lender discretion. Consistent with this hypothesis, SMEs did not draw down whereas large firms did, even in response to similar demand shocks.

I study whether banks' loan loss provisioning contributes to economic downturns, by examining the U.S. housing market. Specifically, I examine the aggregate effects of banks' delayed loan loss recognition (DLR) on house prices during the Great Recession and the channels through which these potential effects arose. I construct ZIP-code-level exposure to banks' DLR before the crisis and compare high- and low-exposure ZIP codes during the crisis to examine the aggregate effects of banks' DLR on the housing market.

It will take an evolution of fixed-income managers’ approach to make a difference to corporate behaviour.

Not to be left out of the ESG gold rush, a growing number of bond firms now offer environmental, social and governance funds. ESG integration has become a standard box to be checked (or not) on bond clients’ Requests for Proposals. Investment banks have created tools to help fixed income managers ESG-ify their portfolios.

We develop a model of information and portfolio choice in which ex ante identical investors choose to specialize because of fixed attention costs required in learning about securities. Without this friction, investors would invest in all securities and would be indifferent across a wide range of information choices. When securities' dividends depend on an aggregate (macro) risk factor and an idiosyncratic (micro) shocks, fixed attention costs lead investors to specialize in either macro or micro information.
