A surprisingly neglected facet of sector evolution is the evolutionary analysis of firms', and thus a sector's, scope. Defining a sector as a group of firms that can change their scope over time, we study the transformation of U.S. banking firms. We undertake a sectoral, population-wide study of...

This paper provides direct evidence of the importance of firm attention to macro-economic dynamics. We construct a text-based measure of firm attention to macro-economic news and document firm attention that is polarized and countercyclical. Differences in attention lead to asymmetric responses...

This paper shows how idiosyncratic resources can be the basis of sustained profitability and persistent heterogeneity under competitive conditions: Generic inputs purchased in the market become idiosyncratic resources by investments in customization. Analytically, we show how heterogeneous firms...

Banks carry significant exposures to nonbanks from direct dealings, but they can also be exposed, indirectly, through losses in asset values resulting from fire-sale events. We assess the vulnerability of U.S. banks to fire sales potentially originating from any of twelve separate nonbank...

The globalization of banking in the United States is influencing the monetary transmission mechanism both domestically and in foreign markets. Using quarterly information from all U.S. banks filing call reports between 1980 and 2005, we find evidence for the lending channel for monetary policy...

We provide a framework for monitoring the shadow banking system. The shadow banking system consists of a web of specialized financial institutions that conduct credit, maturity, and liquidity transformation without direct, explicit access to public backstops. The lack of such access to sources...

I introduce the concept of hybrid intermediaries: financial conglomerates that control a multiplicity of entity types active in the "assembly line" process of modern financial intermediation, a system that has become known as shadow banking. The complex bank holding companies of today are the...

Using a synthetic control research design, we find that "living will" regulation increases a bank's annual cost of capital by 22 basis points, or 10 percent of total funding costs. This effect is stronger in banks that were measured as systemically important before the regulation's announcement....

Loan funds are open-end mutual funds holding predominantly corporate leveraged loans. We document empirically that loan funds are significantly more susceptible to run risk than any other category of debt funds, including corporate bond funds. Most importantly, we establish a link between loan...

Banks have progressively evolved from being standalone institutions to being subsidiaries of increasingly complex financial conglomerates. We conjecture and provide evidence that the organizational complexity of the family of a bank is a fundamental driver of the business model of the bank...
