When a nation can finance its investments via foreign-currency denominated debt or domestic-currency claims, what is the optimal capital structure of the nation? Building on the functions of fiat money as both medium of exchange, and store of value like corporate equity, our model connects...

We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

This paper presents a framework for analyzing the costs and benefits of internal vs. external capital allocation. We focus primarily on comparing an internal capital market to bank lending. While both represent centralized forms of financing, in the former case the financing is owner-provided,...

The leverage effect refers to the generally negative correlation between an asset return and its changes of volatility. A natural estimate consists in using the empirical correlation between the daily returns and the changes of daily volatility estimated from high-frequency data. The puzzle lies...

A review of major lines of thinking about developments in the 1980s bearing on the likelihood of a financial crisis in the United States supports four principal conclusions:First, financial crises have historically played a major role in large fluctuations in business activity. A financial...

Over the past twenty years, macroeconomic performance has improved markedly in industrialized and developing countries alike. Both inflation and real growth are more stable now than they were in the 1980s. This stability has been accompanied by dramatic changes in financial structure. We examine...

We propose that financial institutions can act as asset insulators, holding assets for the long run to protect their valuations from consequences of exposure to financial markets. We demonstrate the empirical relevance of this theory for the balance sheet behavior of a large class of...

This paper introduces the impact of debt misvaluation on merger and acquisition activity. Debt misvaluation helps explain the shifting dominance of financial acquirers (private equity firms) relative to strategic acquirers (operating companies). The effects of overvalued debt might seem limited...

This paper describes interactions between monetary and fiscal policies that affect equilibrium price levels and interest rates by critically surveying theories about (a) optimal anticipated inflation, (b) optimal unanticipated inflation, and (c) conditions that secure a "nominal anchor'' in the...

To prevent firms from manipulating prices, U.S. regulators set price ceilings for open-market share repurchases. We find that market structure reforms in the 1990s and 2000s dramatically increased share repurchases because they relaxed constraints that prevent firms from competing with other...
