Sammanfattning

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.

Sammanfattning

In this paper, we study foreign ownership as a vehicle for transferring gender norms across international borders. Specifically, we analyze how the wage differential between men and women in Swedish firms is affected by the degree of gender inequality in the home country of foreign investors. The results suggest that gender norms of the home country matter—the gender wage gap in foreign-owned subsidiaries appears to increase with the degree of gender inequality prevailing in the investors’ home market. This finding is identified from within job-spell variation in wages and proves robust across a series of specifications.

Sammanfattning

This paper considers a flexible class of asymmetric double Pareto distributions (ADP) that allows for skewness and asymmetric heavy tails. The inference problem is examined for maximum likelihood. Consistency is proven for the general case when all parameters are unknown. After deriving the Fisher information matrix, asymptotic normality and efficiency are established for a restricted model with the location parameter known. The asymptotic properties of the estimators are then examined using Monte Carlo simulations. To assess its goodness of fit, the ADP is applied to companies’ growth rates, for which it is favored over competing models.

Sammanfattning

This paper examines the role of wholesale firms as facilitators of exports for small and medium-sized Swedish businesses. Our findings suggest that wholesale firms do facilitate access to difficult markets located outside Europe. For exports of a particular good to a given market, we observe a positive correlation between the export volumes of wholesale and manufacturing firms. Finally, we present evidence that supports a prediction from recent trade models with differentiated firms, namely that wholesale firms can facilitate exports for firms that are not themselves capable of direct exports.
