The end result is an individual life history and its projection into a future time period.ġ.2 Microsimulation can be a useful tool for policymakers because it allows an evaluation to be conducted of the effects of proposed government policy interventions before they are implemented in the real world. A set of rules (for example transition probabilities) intended to represent individual preferences and tendencies, is then applied to each unit, leading to simulated changes in state and behaviour. In empirical terms, each unit is represented by a data record containing a unique identifier and a set of associated attributes, such as age, gender, marital status and education. Investigation of point estimates and distributions of outcomes can then be performed for a range of heterogeneous subgroups of interest. Microsimulation can be distinguished from other types of computer modelling in that it simulates the state and behaviour of individual units such as people or households and relies on empirical data for initial conditions and rules ( Gilbert and Troitzsch 2005).

Microsimulation, Software Frameworks, Policy Tool, Java, Rġ.1 Microsimulation is an empirically based data modelling methodology traditionally used in the areas of taxation, pensions, and other types of economic activity, but is increasingly being applied to the social sciences ( Brown and Harding 2002). Here we describe microsimulation, our functional requirements, a review of tools used by other micro-simulators and an evaluation of existing software, followed by the architecture, features and use of JAMSIM. Combining the leading open source statistical package R and one of the foremost agent-based modelling (ABM) graphical tools Ascape, JAMSIM is available as an open source tool, for public reuse and modification. JAMSIM (JAva MicroSIMulation) is an innovative synthesis of open source packages that provides an environment and set of features for the creation of dynamic discrete-time microsimulation models that are to be executed, manipulated and interrogated by non-technical, policy-oriented users.
