Orcutt’s Vision, 50 years on
Fifty years have passed since the seminal contribution of Guy Orcutt [Orcutt,1957],which gave birth to the field of Microsimulation. We survey, from a methodological perspective, the literature that followed, highlighting its relevance,its pros and cons vis-`a-vis other methodologies and pointing out the main open issues.
JAS-mine: A new platform for microsimulation and agent-based modelling
We introduce JAS-mine, a new Java-based computational platform that features tools to support the development of large-scale, data-driven, discrete-event simulations. JAS-mine is specifically designed for both agent-based and microsimulation modelling, anticipating a convergence between the two approaches. An embedded relational database management system provides tools for sophisticated input-output communications and data storage, allowing the power of relational databases to be used within an object-oriented framework. The JAS-mine philosophy encourages the separation of distinct concepts, objects and functionalities of the simulation model, and advocates and supports transparency, flexibility and modularity in model design. For instance, JAS-mine allows to store the list of regressors and their estimated coefficients externally to code, making it easy to change the specification of regression models used in the simulation and achieving a complete parallelisation between the tasks of the econometricians and those of the programmers. Moreover, tools for uncertainty analysis and search over the parameter space are also built in
A Population Based Regional Dynamic Microsimulation of Germany: The MikroSim Model
Microsimulation models are widely used to evaluate the potential effects of different policies on social indicators. Most microsimulation models in use operate on a national level, disregarding regional variations. We describe the construction of a national microsimulation model for Germany, accounting for local variations in each of the more than 10,000 communities in Germany. The database used and the mechanisms implementing the population dynamics are described. Finally, the further development of the database and microsimulation programs are outlined, which will contribute towards a research lab that will be made available to the wider scientific community
Agent-based Computational Demography and Beyond using JAS-mine
In this chapter we provide a hands-on guide on how to build a microsimulation using JAS-mine, a Java-based platform that provides unique simulation tools for discrete-event simulations, including both agent-based and microsimulation models. After presenting the rationale for the recent developments of the JAS-mine project and the main architectural choices made, we illustrate a step-by-step implementation of a rich dynamic microsimulation, which includes demographic processes (birth, death, household formation and dissolution) and other life course events (educational choices, labour market participation and employment outcomes).</p
New methods in pension evaluation : Applications of trajectory analysis and dynamic microsimulation
This study gives an overview of two new methods in pension evaluation finite mixture modeling technique called trajectory analysis and dynamic microsimulation. Trajectory analysis and microsimulation can be used to study longitudinal datasets and various topics related to life courses. In this study, the applications of these methods focus on early career labor market attachment, insurance behavior of the self-employed and evaluation of the 2017 pension reform. Furthermore, this study discusses measurement and classification questions in pension research. The analyzes are based on the register data of the Finnish Centre for Pensions.
