In 1997, SESIM was developed as a tool at the Swedish ministry of finance to evaluate the Swedish system to finance higher education. Part of that work was documented in Ericson and Hussénius (2000). We refer to this as version I of SESIM. Focus then shifted from education to pensions. SESIM was used to evaluate the financial sustainability of the new Swedish pension system. This new application implied that SESIM was developed into a general micro-simulation model (MSM) that can be used for a broad set of issues. We refer to this as the second version of SESIM and the documentation is presented in Flood (2003). The present version, SESIM III, maintains the focus on pensions but extends the analyses to include health issues, regional mobility, and wealth.

It is not easy to get a long perspective on the distribution of wealth in Sweden because there is no single data source that gives a consistent view for a long period of time. The early estimates of the distribution of wealth were based on the concept of tax-assessed wealth which is the basis of the wealth tax. This definition has the disadvantage of not including assets that were not taxed, and no or very unreliable data were given for the majority of the tax payers who were below the taxation threshold. Furthermore, this variable was defined for individuals and for jointly taxed individuals, but no economically meaningful household concept was available. Register data have since then improved, in particular after the late 1990s when data became available directly from banks, brokers, and insurance companies without the filtering of the tax payers. The problem with the household definition remains, but in SESIM we have made corrections to get a useful definition (see Chapter 3). A relatively large survey (HEK) run by Statistics Sweden which combines survey information about the household with register data on assets estimates the median household wealth to 156000 SEK in 1999 and 197000 SEK in 2003.² The latter estimate is in the 1999 price level.³ These estimates apply to all households independent of age. As will be shown below, the level of wealth depends very much on age.

Since SESIM is of a fundamental importance for this analysis, we also give a short presentation of the income-generating mechanisms in the model, focusing on earnings and income from capital.

This paper investigates the effect of household size, and in particular of the number of children of different age groups, on poverty, defined as being in a situation of low income. We apply various static and dynamic probit models to control for the endogeneity of the variables of interest and to account for unobserved heterogeneity, state dependence, and serially correlated error components. Using Luxembourg longitudinal data, we show that the number of children of different age groups significantly affects the probability of being poor. However, the magnitude of the effect varies across different specifications. In addition, we find strong evidence of true poverty persistency due to past experience, spurious poverty persistency due to individual heterogeneity, and transitory random shocks.

Soil is a non-renewable and increasingly deteriorating resource, yet it is barely protected by European Union (EU) legislation. This constitutes a puzzling gap within the otherwise encompassing and progressive environmental policy of the EU. To explain the integration resistance of soil protection, I draw on insights from rationalist and sociological institutionalist theory. The institutional rigidity of the community method of environmental decision-making limits policy change to favorable interest constellations, but this constraint is usually compensated by agenda competition among the national environmental pioneers. However, successful agenda-setting depends on the skillful combination of political venues and issue frames. Matters of land politics, such as soil protection, are difficult to frame in terms that make them suitable for European policy venues. The theoretical argument is illustrated using an in-depth case study of the agenda-setting, negotiation, and eventual withdrawal of the ill-fated proposal for an EU soil framework directive, with a focus on the changing role of Germany. Reframing of soil politics as locally bound and as essentially national affair, subnational actors extended the conflict to include the German federal chamber as policy venue. As a result, Germany turned from “pusher by example” and first mover to “defensive front-runner,” successfully pursuing a blocking strategy.

After Papua New Guinea’s contact with the western world several western scholars turned their attention toward the indigenous population and showed a special interest in the cults that were formed afterward as well as the (following) conversions of almost all indigenous population to the Christian faith. While the majority of the literature focuses on this process either as an act of desperation or as one of calculation, this chapter focuses on the practices in the actual process of “becoming a Christian,” viewing them as expressions of self-change and thus offering a new perspective for understanding those changes. Drawing on and expanding interactionist ideas of dramatic self-change, this chapter identifies the practices used to portray that a change of identity has occurred. Data was gathered through the analysis of existing anthropological and ethnological work, which provides information about a broad range of tribes, yet is limited to the information provided by the respective researcher. The practices found are divided into practices which need not be secured, which demonstrate the acceptance of the new religion in a way that is usually not challenged (like public confessions, verbal denigration of the old tradition, integration into the new structure, adopting new symbols, and destroying the old) and practices that need to be secured, ones which might be regarded as odd (like dramatizing enlightenment) and thus need another way of accounting to secure them from being challenged.
