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 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 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...

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...

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...

Many stylized facts of leverage, trading, and asset prices obtain in a frictionless general equilibrium model that features agents' heterogeneity in endowments and habit preferences. Our model predicts that aggregate debt increases in expansions when asset prices are high, volatility is low, and...

Money is debt that circulates with no questions asked. Stablecoins are a new form of private money that circulate with many questions asked. We show how stablecoins can maintain a constant price even though they face run risk and pay no interest. Stablecoin holders are indirectly compensated for...

We explore the consequences of global capital market segmentation by currency for the optimal currency composition of borrowing by firms. Global bond portfolios are driven by the currency of denomination of assets as investors prefer to lend in their home currency or the international currency,...

We provide new evidence that debt creates shareholder value for firms that face agency costs. Our tests are unique in two respects. First, we focus on a sample of firms with potentially extreme agency problems. We study emerging market firms where the routine use of pyramid ownership structures...
