Constructing an Urban Population Model for Medical Insurance Scheme Using Microsimulation Techniques

China launched a pilot project of medical insurance reform in 79 cities in 2007 to cover urban nonworking residents. An urban population model was created in this paper for China's medical insurance scheme using microsimulation model techniques. The model made it clear for the policy makers the population distributions of different groups of people, the potential urban residents entering the medical insurance scheme. The income trends of units of individuals and families were also obtained. These factors are essential in making the challenging policy decisions when considering to balance the long-term financial sustainability of the medical insurance scheme

Constructing a Basefile for Simulating Kunming’s Medical Insurance Scheme of Urban Employees

Focusing on China’s medical insurance scheme which covers all employers and employees in urban areas, this research aims to assess the distributional impacts of medical insurance policies and to predict medical expenses by using microsimulation techniques. As an important part of the project, this article provides a brief overview of China’s medical insurance reform of urban employees and detail the techniques and processes to construct a basefile in 2005 for projecting the medical expenditures for urban employees over the period of 2006-2010. The main data used are administrative medical records of medical insurance participants provided by the Bureau of Labour and Social Security of Kunming, Yunnan Province. Along with the initial analysis for the raw datasets and age processing and adjustment for the individual records, monthly income information was imputed and personal savings accounts were established for each individual record. Important modelling parameters such as death rates and income adjustment factors were constructed. Furthermore, this article identifies medical insurance for government officials by using the combination of logarithm curve fitting and binary discriminant analysis. Based on this basefile, a static microsimulation model can be built to assess the implementation effects of the medical insurance policy and analyse the impact of the medical insurance scheme on urban employees.Urban medical insurance, China, microsimulation, basefile, Policy Research

Challenges and Solutions in Constructing a Microsimulation Model of the Use and Costs of Medical Services in Australia

This paper describes the development of a microsimulation model =HealthMod‘ which simulates the use and costs of medical and related services by Australian families. Australia has a universal social insurance scheme known as =Medicare‘ which provides all Australians with access to free or low-cost essential medical services. These services are provided primarily by general practitioners as well as specialist doctors but also include diagnostic and imaging services. Individuals may pay a direct out-of pocket contribution if fees charged for services are higher than the reimbursement schedule set by government. HealthMod is based on the Australian 2001 National Health Survey. This survey had a number of deficiencies in terms of modelling the national medical benefits scheme. The article outlines three major methodological steps that had to be taken in the model construction: the imputation of synthetic families, the imputation of short-term health conditions, and the annualisation of doctor visits and costs. Some preliminary results on the use of doctor services subsidised through Australia‘s Medicare are presented.Economic microsimulation modelling, medical services, use and costs, Australia

Editorial - Special Issue on Health

This special issue is a collection of articles that had their origins as papers presented at the 1st General Conference of the International Microsimulation Association (IMA) “Celebrating 50 years of Microsimulation” Vienna, Austria, 20th to 22nd August 2007. The papers all discuss the development and application to policy of dedicated health microsimulation models. These models and applications are testimony to the realisation of Orcutt’s original vision in the late 1950's and early 1960's of applying microsimulation techniques to socio-economic modelling, expanding from the earlier focus on taxation and public transfers into the areas of health and ageing.health, microsimulation

Poverty among the Elderly in Latin America and the Caribbean

This paper provides evidence on the incidence of poverty among the elderly in Latin America and the Caribbean, based on household survey microdata from 20 countries. The situation of older people is characterized in terms of income, employment, education, health and access to services vis-à-vis the rest of the population. The paper identifies the role played by the current pension systems in Latin America, and assesses the efforts needed to achieve substantial improvements toward the reduction of old-age poverty.elderly, ageing, poverty, Latin America, Caribbean
