This paper introduces a generalised model building platform (MMEANS) for implementing and using tax-benefit microsimulation models. It is designed to aid in the construction of single- and multi-country tax- benefit models by providing all essential components and a system by which these can be...

In this paper, we survey the use of nowcasting methods in Microsimulation models. These nowcasting methods differ in a number of respects to the more established methods of forecasting. The main distinction is that while forecasting extrapolates from current data to estimate the future, the...

Alignment is a widely adopted technique in the field of microsimulation for social and economic policy research. However, limited research has been devoted to understanding the statistical properties of the various alignment algorithms currently in use. This paper discusses and evaluates six...

Most existing microsimulation models have been developed by separate (teams of) researchers. The drawback of each team working on its own is that they have to put a lot of time and effort in the customary development of fairly general simulation tools. Hence, economies of scale cannot be...

This paper studies the redistribution effect of personal income tax in Pakistan. We decompose the overall tax system in order to evaluate the contribution of rate, allowances, deductions, exemptions and credits. The structure given in Income Tax Ordinance, 2001, is applied to gross household...

This paper describes some of the issues related to constructing a dynamic microsimulation model. The paper considers the principle choices facing the model builder. These choices are whether the model should be probabilistic or incorporate behavioural response, whether model runs in discrete or...

Household micro-datasets often do not contain information on gross incomes. We present an algorithm which exploits the tax- and contribution rules built into tax-benefit models to convert net income information into gross amounts. Using EUROMOD, a multi-country taxbenefit model covering all...

Although demographic ageing will affect Ireland later than many EU countries, by 2050 it will result in significant pressures on the public pension system. Recent reform in Ireland has attempted to address these pressures by increasing the incentive to save for retirement and by introducing...

This paper studies the impact of changes in the external balance of a developing economy (Pakistan). We explain that the economic growth achieved during the past decade is highly dependent on the improvements in external balance. Between 2001 and 2007 Pakistan has benefited from, an increase in...

This paper considers the methodology of measuring replacement rates, comparing simulation based approaches, which simulate replacement rates for a representative sample of the population, with other approaches that simulate replacement rates for "typical" families or are entirely based on...
