The standard workhorse models of monetary policy now commonly in use, both for teaching macroeconomics to students and for supporting policymaking within many central banks, are incapable of incorporating the most widely accepted accounts of how the 2007-9 financial crisis occurred and incapable...

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...

When the composition of assets outstanding in the market changes, the pattern of expected asset returns also changes, shifting to whatever return structure will induce investors to hold just the new composition of exisiting assets. The object of this paper is to determine, on the basis of the...

The object of this essay is to gain an overview of developments in theAmerican financial markets since World War II, with particular attention to changes that have occurred either between the prewar and post-war years or within the past several decades. Inevitably such an effort must be...

Among the numerous familiar sets of specific assumptions sufficient to derive mean-variance portfolio behavior from more general expected utility maximization in continuous time, the assumptions of constant relative risk aversion and joint normally distributed asset return assessments are also...

The extraordinary increase in reliance on debt by U.S. business in the 1980s has generated widespread concern that overextended borrowers may become unable to meet their obligations and that proliferating defaults could then lead to some kind of rupture of the financial system, with ensuing...

The principal rationales that give rise to financial intermediation are benefits of size and specialization, the diversification of specific asset risks, and the pooling of even broader classes of risk. Each is a significant factor in accounting for the U.S. economy's reliance on intermediation....

Empirical results based on two different statistical approaches lead to several conclusions about the role of time-varying asset risk assessments in accounting for what, on the basis of many earlier studies, appear to be time-varying differentials in ex ante asset returns. First, both methods...

The three sections of this paper support three related conclusions. First, asset demands with the familiar properties of wealth homogeneity and linearity in expected returns follow as close approximations from expected utility maximizing behavior under the assumptions of constant relative risk...

What stands out in retrospect about U.S. monetary policy during the Greenspan Era is the ongoing movement away from mechanistic restrictions on the conduct of policy, together with a willingness on occasion to depart even from what more flexible guidelines dictated by contemporary conventional...
