The tax-payer-as-gambler (TAG) model of tax non-compliance is the classic vehicle for providing some simple insights. Under fairly general conditions this model supports the following four propositions: (1) if the rate of return to evasion is positive everyone evades tax; (2) people with higher...

The May 2007 issue of the Journal of Monetary Economics published a paper of mine entitled ‘Investment-Specific Technological Progress and Growth Accounting’ which critiqued the work of Greenwood, Hercowitz and Krusell. I argued that the Greenwood-Hercowitz-Krusell (GHK) model is a special...

This paper proposes an empirically feasible method for correcting the path-dependence bias of chain indices of the cost of living. Chain indices are discrete approximations to Divisia indices and it is well known that the latter are path-dependent: the level of a Divisia index is affected not...

Building on previous studies on perceptions of inequality, welfare and risk we investigate the structure of individuals' rankings of uncertain prospects in terms of risk and their relationship to individual preferences. We examine three interlinked propositions that are fundamental to the...

Studies of firm-level data have shown that there is a huge dispersion of productivity across firms even when industries are narrowly defined. So there is a significant opportunity for the least productive firms to catch up to the most productive. The formers’ convergence could therefore...

If the rich just get richer and the poor get poorer, the answer might seem easy. But what if the income distribution changes in a complicated way? Can we use mathematical or statistical techniques to simplify the comparison problem in a way that has economic meaning? What does it mean to measure...

Modelling Lorenz curves (LC) for stochastic dominance comparisons is central to the analysis of income distribution. It is conventional to use non-parametric statistics based on empirical income cumulants which are in the construction of LC and other related second-order dominance criteria....

We study the impact of private ownership, incentive pay and local development objectives on university licensing performance. We develop and test a simple contracting model of technology licensing offices, using new survey information together with panel data on U.S. universities for 1995-99. We...

We study the impact of incentive pay, local development objectives and government constraints on university licensing performance. We develop and test a simple contracting model of technology licensing offices, using new survey information together with panel data on U.S. universities for...

The commercial value of basic knowledge depends on the arrival of follow-up developments mostly from outside the boundaries of the inventing firm. Private returns would depend on the extent the inventing firm internalizes these follow-up developments. Such internalization is less likely to occur...
