Abstract

This paper empirically examines industry determinants of the shape of Swedish firm size distributions at the 3-digit (NACE) industry level between 1999-2004 for surviving firms. Recent theoretical studies have begun to develop a better understanding of the causal mechanisms behind the shape of firm size distributions. At the same time there is a growing need for more systematic empirical research. This paper therefore presents a two-stage empirical model, in which the shape parameters of the size distribution are estimated in a first stage, with firm size measured as number of employees. In a second stage regression analysis, a number of hypotheses regarding economic variables that may determine the distributional shape are tested. The result from the first step are largely consistent with previous statistical findings confirming a power law. The main finding, however, is that increases in industry capital and financial constraint exert a considerable influence on the size distribution, shaping it over time towards thinner tails, and hence fewer large firms.

Abstract

This paper examines whether the Swedish regulatory system of dealing with industrial conflicts that affect essential services need an update or reform. Are the existing rules effective in a world where many essential services are upheld by many interdependent agents in complex systems where every single node becomes critical for the functioning of the system, and where the essential service activities could be either private or public? A comparative study is conducted with the corresponding regulatory systems of the United Kingdom, Germany, and Denmark.
The conclusion is that Sweden is a special case. The Swedish protection against and readiness in dealing with societally harmful industrial conflicts in essential services is weaker than in the countries of comparison. Just as in relation to other threats to essential services, it is not sustainable to claim that just because such a threat is not currently present, there would be no need for preparedness.
There are many alternative ways to handle this. Desirable methods should both prevent harmful conflicts from erupting and end conflicts that have grown harmful to society at a later stage. The labour market organisations should have a mutual interest in reforming the rules.

Abstract

The purpose of this paper is to study how municipalities work at the regional level with issues concerning skills shortages and recruitment. What information channels are used to obtain information about these shortcomings? How and with whom do the municipalities collaborate? This study provides a mapping of how collaboration between employers, regional policymakers, and other institutions works with regional recruitment. As such, this study provides important information and possible inspiration. The empirical findings obtained based on a survey targeted to the business sections in Swedish municipalities suggest that companies in rural regions turn to municipalities to a greater extent than companies in non-rural municipalities in regard to skills shortages and recruitment. In addition, it is perceived that there is a higher degree of cooperation between businesses and local politicians in regard to recruitment in rural municipalities compared to other municipalities. Even cooperation to develop competence at the regional level is thought to take place to a greater extent in rural municipalities than in non-rural municipalities.
