We set out a simple four sector macro model of the economy of the Roman Empire during a period of considerable economic prosperity. Our focus is on gold coins as currency and the seignorage which the government used to fund its activities. We solve numerically for a balanced growth...

We know that people strike bargains and that civilized life could not proceed otherwise. We do not know how bargains are struck. We have no explanation of bargaining, comparable to the general equilibrium in the economy, accounting for essential features of bargaining as we know it with...

Economists do not understand how bargains are struck. A bargain is the sharing of a pie between two or more people who are collectively entitled to the pie but cannot appropriate it until they agree how large each person's slice is to be. We know that people do strike bargains and that civilized...

It has long been recognized that solving the logical omniscience problem requires using some kind of nonstandard possible worlds. While many such logics have been proposed, none has an obvious claim as the "right" logic to use to describe the reasoning of agents who are not logically omniscient....

We study the optimal redistributive tax structure when the population can be disaggregated into tagged groups. We begin with the case in which the tag has no normative significance, but simply separates the population into identifiable groups with different distributions of ability-types. Under...

This paper derives optimal commodity taxes in a two-class economy, based on Chaudhuri (1986) and Diamantaras and Thomson's (1990) λ-equitability. An allocation is λ-equitable if no agent envies a proportion λ of the bundle of any other agent. We examine the properties of Pareto undominated...

Through tax evasion, through the labour-leisure choice or in other ways, taxpayers reduce the tax base in response to an increase in the tax rate. The process is commonly-believed to generate a humped Laffer curve with a revenue-maximizing tax rate well short of 100%. That need not be so. In the...

We examine how the introduction of self-control preferences influences the trade-off between two fundamental components of a public pension system: the contribution rate and its degree of redistribution. The pension regime affects individuals' welfare by altering how yielding to temptation (i.e....

A common, though by no means universally-accepted doctrine among practitioners of law and economics is that redistribution is no business of the law. This efficiency-only doctrine is not that redistribution is unworthy as a social objective, but that any given benefit to the poor is attainable...

Tax analysis and forecasting of revenues are of critical importance to governments in ensuring stability in tax and expenditure policies. To augment timely and effective analysis of the revenue aspects of the fiscal policy, governments have increasingly turned toward in-house tax policy units...
