The General Theory of Tax Avoidance

This paper outlines a general set of principles for tax avoidance. Most of at least the common tax avoidance schemes can be reinterpreted as making use of one or more of these principles. Four such methods are described. In a perfect capital market, these methods would enable the astute taxpayer to eliminate all taxation on capital income. The fact that the tax system raises revenue is attributed to lack of astuteness of the taxpayer and/or lack of perfection of the capital market. Accordingly, models which attempt to analyze the effects of taxation assuming rational, maximizing taxpayers working within a perfect capital market may give misleading results.A full analysis of tax avoidance cannot be conducted within a partial equilibrium model; transactions which reduce one individual's tax liability may at the same time increase another's.We delineate tax avoidance schemes which reduce the aggregate tax liabilities of the participants. Much of the"general equilibrium" gain from tax avoidance arises from differences in tax rates, both across individuals and across classes of income. Our analysis is shown to have implications both for patterns of ownership of assets and the timing of transfers.

Money, Credit, and Business Fluctuations

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 and processing of information. Like many other economic activities involving information, these processes are not well described by means of standard production functions. Changes in economic circumstances can have marked effects on the relevance of previously accumulated information and accordingly on the supply of credit. Changes in the availability of credit may have marked effects on the level of economic activity, while changes in real interest rates seem to play a relatively minor role in economic fluctuations. This alternative view has a number of implications for policy, both at the macro-economic level (for instance, on the role of monetary policy for stabilization purposes and the choice of targets) and at the micro-economic level.

Economics of Information and the Theory of Economic Development

This paper shows how recent developments in the Economics of Information can provide insights into economic relations in less developed countries, and how they can provide explanations for institutions which, in neoclassical theory, appear anomalous and/or inefficient. Sharecropping and other tenancy relationships in the rural sector and wage determination and urban unemployment are both investigated within this perspective.

The creation of the rule of law and the legitimacy of property rights : the political and economic consequences of a corrupt privatization

How does the lack of legitimacy of property rights affect the dynamics of the creation of the rule of law? The authors investigate the demand for the rule of law in post-communist economies after privatization under the assumption that theft is possible, that those who have"stolen"assets cannot be fully protected under a change in the legal regimetoward rule of law, and that the number of agents with control rights over assets is large. They show that a demand for broadly beneficial legal reform may not emerge because the expectation of weak legal institutions increases the expected relative return to stripping assets, and strippers may gain from a weak and corrupt state. The outcome can be inefficient even from the narrow perspective of the asset-strippers.Legal Products,Economic Theory&Research,Corruption&Anitcorruption Law,Public Sector Corruption&Anticorruption Measures,Governance Indicators

Vertical Restraints and Producers' Competition

This paper examines the rationale for vertical restraints. It shows that there are important circumstances under which these restrictions have significant anti-competitive effects. The paper focuses on the consequences of exclusive territorial arrangements among the retailers of two products which are imperfect substitutes. Such arrangements are shown to increase consumer prices; under plausible conditions the increase in consumer prices is sufficiently large to more than offset the deleterious effects from "double marginalization" resulting from reduced competition among retailers. The imposition of exclusivity provisions is may be part of a Nash equilibrium among producers. These results hold whether there are or are not franchise fees.

Macro-Economic Equilibrium and Credit Rationing

In this paper we investigate the macro-economic equilibria of an economy in which credit contracts have both adverse selection and incentive effects. The terms of credit contracts include both an interest rate and a collateral requirement. We show that in this richer model all types of borrowers may be rationed. Interest rates charged borrowers may move either pro or counter-cyclically. If pro-cyclical shocks have a greater effect on the success probabilities of risky techniques than on safe ones, then the interest rate offered depositors may also move counter-cyclically. Finally, we show that the impact of monetary policy on the macro-economic equilibrium is affected by whether or not the economy is in a regime in which credit is rationed.

Money, Imperfect Information and Economic Fluctuations

This paper summarizes the macro-economic and, in particular, monetary and financial market implications of recent developments in the micro-economic theory of imperfect information. These micro-economic models which lead to credit-rationing on the one hand and limitations in the availability of equity type financing on the other can account for a wide range of observed business cycle and monetary phenomena. These include (a) unemployment, (b) the existence of Keynesian-type multiples, (c) the observed lack of production smoothing in response to cyclical fluctuations in demand, (d) the impact of monetary policy on business activity despite the absence of significant changes in real interest rates, and (e) price rigidities which arise from rational firm decisions (not as an a priori assumption).
