    Entrepreneurship and income inequality

    PublicationArticle (with peer review)
    Arbetsmarknad, Daniel Halvarsson, Entreprenörskap, Inkomstfördelning, Karl Wennberg, Martin Korpi, Ojämlikhet

    Abstract

    Entrepreneurship research highlights entrepreneurship as a simultaneous source of enhanced income mobility for some but a potential source of poverty for others. Research on inequality has furthered new types of models to decompose and problematize various sources of income inequality, but attention to entrepreneurship as an increasingly prevalent occupational choice in these models remains scant. This paper seeks to bridge these two literatures using regression-based income decomposition among entrepreneurs and paid workers distinguishing between self-employed (SE) and incorporated self-employed (ISE) individuals in Sweden. We find that the proportion of self-employed in the workforce increases income dispersion by way of widening the bottom end of the distribution, whereas the proportion of incorporated self-employed contributes to income dispersion at the top end of the distribution. Implications for research are discussed.

    Entrepreneurship Theory and Practice (ETP)

    Abstract

    Configurational research has great promise in entrepreneurship. There are few universal laws or relationships that hold under all circumstances. More often, optimal entrepreneurial outcomes are contingent on many factors. Consequently, configurational analysis using qualitative comparative analysis (QCA) has become increasingly popular. However, methodological research in sociology and political science has raised concerns about possible false positive findings produced by this method. In this editorial, we explore the potential and the common pitfalls of QCA in entrepreneurship research, as well as guidelines for its use.

    Abstract

    This study investigates the relationship between the urban wage premium and employer concentration using Swedish full population employer-employee data. Departing from an AKM modeling framework to distinguish worker from firm specific heterogeneity – a measure of rent-sharing – we then measure the urban wage premium using differences in the estimated firm fixed effects at the level of local industries, nested within local labor markets. Our results suggest that labor market employer concentration, as calculated using the Hirschman-Herfindahl index and a leave-one-out instrumental variable design, can account for a significant share of the estimated urban wage premium (UWP). Addressing city-level wage income inequality by applying our model to different segments of the local labor market income distribution, we find that while the UWP pertains to all income segments, it is largest for top-income levels (above the 90th percentile), and within this segment employer concentration also has the largest explanatory power. Thus, while being an important explanatory factor for all percentiles of the local income distribution, a relatively lower employer concentration within larger cities, and vice versa, higher concentration within smaller cities, primarily help explain the variance of top wages within these cities/labor markets.

    Seeking opportunity or socio-economic status? Housing and school choice in Sweden

    Abstract

    Residential choices and school choices are intimately connected in school systems where school admission relies on proximity rules. In countries with universal school choice systems, however, it remains an open question whether families’ residential mobility is tied to the choice of their children’s school, and with what consequences. Using administrative data on all children approaching primary-school age in Sweden, we study to what extent families’ financial and socio-economic background affects mobility between neighbourhoods and the characteristics of schools chosen by moving families. Our findings show that families do utilise the housing market as an instrument for school choice over the year preceding their firstborn child starting school. However, while families who move do ‘climb the social ladder’ by moving to neighbourhoods with more households of higher socio-economic status, their chosen schools do not appear to be of higher academic quality compared to those their children would otherwise have attended.
