Corporate Finance

Being a successful manager or entrepreneur in the media and digital sector requires creativity, innovation, and performance. It also requires an understanding of the principles and tools of management. Aimed at the college market, this book is a short, foundational volume on media management. It summarizes the major dimensions of a business school curriculum and applies them to the entire media, media-tech, and digital sector. Its chapters cover—in a jargonless, non-technical way—the major functions of management.

We establish several facts about the aggregate idiosyncratic variances of equity markets in 23 countries. First, we document strong global commonality in aggregate idiosyncratic variances of returns and cash flows across countries. Second, the global and country level common factors of the idiosyncratic return and cash flow variances are mostly but not always countercyclical. Third, the time series variation of these common factors in idiosyncratic variances of returns and cash flows are highly correlated.

Shadow bank market share in residential mortgage origination nearly doubled from 2007 to 2015, with particularly dramatic growth among online "fintech" lenders. We study how two forces, regulatory differences and technological advantages, contributed to this growth.

The modern notion of an international currency involves use in areas of international finance and trade that extend well beyond central banks' coffers. In addition to their important roles as foreign exchange reserves, international currencies are most frequently used to denominate corporate and government bonds, bank loans, and import and export invoices. These currencies offer unrivaled liquidity, constituting large shares of the volume on global foreign exchange markets, and are commonly chosen as the anchors targeted by countries with pegged or managed exchange rate regimes.

We use a very accurate panel of all individual spending, income, balances, and credit limits from a financial aggregation app and document significant payday responses of spending to the arrival of both regular and irregular income. These payday responses are clean, robust, and homogeneous for all income and spending categories throughout the income distribution. Spending responses to income are typically explained by households' capital structures: households that hold little or no liquid wealth have to consume hand-to-mouth.

This paper studies how hedge fund activism impacts corporate innovation. Firms targeted by activists improve their innovation efficiency over the five-year period following hedge fund intervention. Despite a tightening in research and development (R&D) expenditures, target firms increase innovation output, as measured by both patent counts and citations, with stronger effects among firms with more diversified innovation portfolios. Reallocation of innovative resources, redeployment of human capital, and change to board-level expertise all contribute to improve target firms' innovation.

We examine the Cochrane and Piazzesi (2005, 2008) model in several out-of-sample analyzes. The model's one-factor forecasting structure characterizes the term structures of additional currencies in samples ending in 2003. In post-2003 data one-factor structures again characterize each currency's term structure, but we reject equality of the coefficients across the two samples. We derive some implications of the model for the predictability of cross-currency investments, but we find little support for these predictions in either pre-2004 or post-2003 data.

We propose a new theory of Optimum Currency Areas (OCAs) based on monetary sovereignty. We consider two economically integrated countries with separate currencies and monetary policies, but with exchange rate underreaction. We show that the two countries are then engaged in a strategic monetization game, which may generate excessive inflation in equilibrium. A monetary union between the two countries can eliminate this excess inflation cost, but also removes a nation's monetary sovereignty.

We develop a theory of banking that explains why banks started out as commodities warehouses. We show that warehouses become banks because their superior storage technology allows them to enforce the repayment of loans most effectively. Further, interbank markets emerge endogenously to support this enforcement mechanism. Even though warehouses store deposits of real goods, they make loans by writing new "fake" warehouse receipts, rather than by taking deposits out of storage.
