This paper aims to present the Difference-in-Differences (DiD) method in an accessible language to a broad research audience from a variety of management-related fields.

The paper describes the DiD method, starting with an intuitive explanation, goes through the main assumptions and the regression specification and covers the use of several robustness methods. Recurrent examples from the literature are used to illustrate the different concepts.

By providing an overview of the method, the authors cover the main issues involved when conducting DiD studies, including the fundamentals as well as some recent developments.

The paper can hopefully be of value to a broad range of management scholars interested in applying impact evaluation methods.

The purpose of this paper is to analyze the impact of categorization endogeneity (CE), meant as the influence of endogenous elements (e.g. behavioral traits) in group categorization, in the persistence of group inequality.

The author integrates economic and sociological elements in a dynamic model of human capital accumulation by phenotypically distinct individuals. Both kinds of elements are influenced by the degree of CE.

Effect of CE in the incentive of members of dominated groups to accumulate human capital is twofold: it allows them to pass as belonging to the dominant group but, on the other hand, it reduces the social pay-off stemming from such behavior, as they may be “expelled” from the reference group by their peers. It is found that, under sufficiently low levels of discrimination, CE widens the range of values of the neighborhood effects parameter for which group inequality is stable.

Despite the endogeneity of categorization has been explored in other studies, this is the first one which argues that this element may underpin, under certain conditions, group inequality regarding human capital accumulation. The results presented here sheds some light on real-world issues, as the nature of neighborhood effects, the role of segregation on the maintenance of racial inequality and public policies to combat group inequality.

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.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The purpose of this paper is to provide an overview of the issue of social assistance receipt among immigrants to Sweden and compare to receipt by natives.

The paper describes the institutional background, reports statistical information and surveys the literature on the immigrant‐native disparity in social assistance receipt.

Most out‐payment for social assistance in Sweden refers to foreign‐born persons, a category comprising 14 percent of the population. Immigrants tend to assimilate out of social assistance receipt. However, receipt continues to be higher many years after immigration among immigrants from non‐rich countries than for natives with several identical characteristics. The elevated probabilities of social assistance receipt among immigrants from non‐rich countries are interpreted to be mainly due to failed integration into the labor market at the destination.

Policies for integrating immigrants into the labor market are also policies for reducing social assistance receipt among immigrants and reducing immigrant‐native social assistance disparity. However, other factors such as the structure of Swedish welfare policy play a role as well.

This is the first survey of the literature on disparities in social assistance receipt between immigrants and natives in Sweden.
