The purpose of the paper is to provide a discussion of the various approaches for accounting for labour supply responses in microsimulation models. The paper focuses attention on two methodologies for modelling labour supply: the discrete choice model and the random utility - random...

Existing tax schedules are often overly complex and characterized by discontinuities in the marginal tax burden. In this paper we propose a class of progressive smooth functions to replace personal income tax schedules. These functions depend only on three meaningful parameters, and avoid the...

This paper studies optimal unemployment benefit levels and optimal proportional income tax rates over the business cycle. Previous research suggests that policy makers should make unemployment insurance (UI) dependent on the business cycle because the UI system can be used to smooth consumption...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

Comprehensive modelling of the impact of taxes and tax policy options requires data on the impact at micro-level of both direct and indirect taxes. There are, however, limits on the amount of data that can be gathered by any one survey. With some exceptions, most notably the Living Costs and...

In 2007 and 2008 Polish governments introduced a series of reforms which led to a substantial reduction in the tax "wedge" (in Polish: "klin") on labour. We show that when considered together the package of introduced reforms brought much greater reductions in the tax burden compared to a widely...

The Mirrlees Review of the UK tax system, together with its companion volume of research papers, can be expected to influence future discussions of tax reform. Indeed, this can already be recognised in the Henry Review. As far as income taxation is concerned, the most substantive recommendation...

We estimate the responses of gross labor earnings with respect to marginal and average net-of-tax rates in France over the period 2003-2006. We exploit a series of reforms to the income-tax and the payroll-tax schedules that affect individuals who earn less than twice the minimum wage. Our...

The purpose of SWEtaxben is to evaluate the impact of changes in the tax/benefit systems on households as well as the central governmental budget. Relating to the micro simulation literature this model can be labeled a static micro simulation model with behavioral changes. This behavioral change...

Entrepreneurial activity is often regarded as an engine for economic growth and job creation. Through tax policy, governments possess a potential lever to influence the decisions of economic agents to start and close small businesses. In Germany, the top marginal income tax rates were reduced...
