This paper develops a simple framework to analyze the links between corruption and the unofficial economy and their implications for the official economy. In a model of self-selection with heterogeneous entrepreneurs, we show that the entrepreneurs option to flee to the underground economy...

This paper provides a conceptual review of how the impact of taxes on the incentive to invest in the corporate sector can be measured. The focus is on measures derived from economic theory. Two measures are derived effective marginal and average tax rates which reflect different forms of...

We look at the tax burden on direct investment from three perspectives. The first section illustrates how the recognition of company tax planning and of the importance of intellectual property affects measures of effective tax rates. It also discusses the methodological issues that arise, such...

This paper examines the impacts of a wide range of tax provisions on the incentive to invest in human capital, and shows how these effects can be quantified using effective tax rates, or ETRs. For individuals with median earnings, ETRs on the human capital formed in first-degree university study...

Measuring effective tax rates using tax revenue data is attractive, given that revenues collected capture the net effect of tax provisions and taxpayer behaviour that are difficult to model. Yet reliance on aggregate tax and income data requires restrictive assumptions and significantly limits...

This paper outlines the methodology used by the OECD in its Taxing Wages publication, compares this approach to other measures of the effective tax rate on labour and uses recent results to illustrate its use. It argues that the strength of this methodology lies in its ability to make...

This paper explores the empirical properties of alternative measures of the taxation of income from capital, using UK data over the last thirty years. We analyse measures of effective marginal and average tax rates, based on applying the legal parameters of the tax system to a hypothetical...

This paper analyzes the incentive properties of the standard and burden of proof for a finding of negligence, when evidence is imperfect and rests with the parties. We show that the preponderance of evidence' standard provides maximal incentives to exert care. This holds even though litigants...

In this paper we construct a stylised general equilibrium macromodel to show that demand led expansions may have unexpected effects when market imperfections lead to changes in labour productivity. We find some empirical support, from a number of European countries, for the main predictions of...

The macroeconomic effects on growth, investment and private sector employment of different ways of rolling back the welfare state are analysed. Cutting public spending on private goods induces a lower interest rate, a higher wage, a lower capital stock and a fall in employment. Cutting public...
