This paper provides a critique of standard theories of money, in particular those based on money as a medium of exchange. Money is important because of the relationship between money and credit. The process of judging credit worthiness, in which banks play a central role, involves the collection...

The optimal income taxation problem has been extensively studied in one-period models. This paper analyzes optimal income taxation when consumers work for many periods. We also analyze what information, if any, that the government learns about abilities in one period can be used in later periods...

The optimal income taxation problem has been extensively studied in one- period models. When consumers work for many periods, this paper analyzes what information, if any, that the government learns about abilities in one period can be used in later periods to attain more redistribution than in...

This paper provides an explanation for situations in which the state variables describing the economy do not change, but aggregate consumption experiences significant changes. We present a theory of pseudo-wealth—individuals' perceived wealth that is derived from heterogeneous beliefs and...

This paper, an extension of the Presidential Address to the International Economic Association, evaluates alternative strands of macro-economics in terms of the three basic questions posed by deep downturns: What is the source of large perturbations? How can we explain the magnitude of...

The optimal income tax problem, since it requires self-selection constraints which define nonconvex feasible sets, is one of the many problems in economics for which randomization in the solution may be desirable. For a two-class economy. we characterize the optimal random tax schedules and we...

This paper surveys recent developments in the theory of pareto efficient taxation. This literature attempts to characterize those tax structures which, given the limitations on the government's information and other limitations on the government's ability to impose taxes, maximize the welfare of...

When government expenditures exceed current tax revenues, the resulting deficit must be financed either by issuing bonds, which imply obligations to levy future taxes, or by creating high-powered money. The choice between money and bonds is often thought to be of great moment for both real and...

Schumpeter argued that economic downturns had positive effects, in the incentives that it provided for firms to increase their efficiency. Part 1. provides a simple model confirming Schwnpeter's insight At thesame time, the model shows that there are real costs to economic fluctuations which...

This paper shows that the patterns of optimal tax rates and borrowing in the presence of endogenous borrowing constraints differ considerably from the patterns observed with fully integrated capital markets. We study a developing country characterized by a costly tax collection. Its access to...
