ItemDiscrete hours labour supply modelling: Specification, estimation and simulation(John Wiley & Sons, 2005)The assumption behind discrete hours labour supply modelling is that utility-maximising individuals choose from a relatively small number of hours levels, rather than being able to vary hours worked continuously. Such models are becoming widely used in view of their substantial advantages, compared with a continuous hours approach, when estimating and their role in tax policy microsimulation. This paper provides an introduction to the basic analytics of discrete hours labour supply modelling. Special attention is given to model specification, maximum likelihood estimation and microsimulation of tax reforms. The analysis is at each stage illustrated by the use of numerical examples. At the end, an empirical example of a hypothetical policy change to the social security system is given to illustrate the role of discrete hours microsimulation in the analysis of tax and transfer policy changes.

ItemRevenue Elasticities in Complex Income Tax Structures: An Application to Spain(WILEY, 2010-12)Abstract This paper derives analytical expressions for the revenue elasticity of complex income tax systems, as applied to tax units and in aggregate. Among the complexities considered are the schedular nature of income tax systems and the role of central and regional governments, along with the existence of a range of intricate tax credits and eligible expenditures and deductions. Empirical estimates are obtained for the case of Spain using a cross‐sectional data set, which enables a number of important ancillary elasticities (relating to allowances and tax credits, and different income sources) to be estimated. It is found that there is considerable variation among tax units in the revenue elasticity, with highly positively skewed distributions. The nature of the distributions varies among regions of Spain, and the aggregate elasticities for each region were found to display some variation associated with income distribution differences. The national aggregate is found to be around 1.3.
