Microdata Evidence on Rent-Sharing

We examine the effect of firm profits on wages for individual workers while focusing on the empirical complications associated with estimating the extent of rent-sharing. Controlling for worker and firm fixed-effects and using several instruments to deal with the endogeneity of profits, we report results indicating that Ordinary Least Square (OLS)-estimates strongly underestimate the effects of profits on wages. Moreover, the effect of profits on wages are estimated separately for firms with increasing and decreasing profits within a given time period. We find a positive and stable effect only in firms with increasing profits. This is in line with the idea that falling profits do not lead to wage cuts while increasing profits imply higher wages.

Firm Size or Firm Age? The Effect on Wages Using Matched Employer-Employee Data

This paper uses matched employer-employee data set for Sweden to study the relationship between firm age and wages, systematically addressing a variety of possible explanations for observing a firm age-wage effect. Results show considerable heterogeneity across years, along segments of the firm age distribution and across industries. For 1995, a positive relationship is found between firm age and wages. This relationship is robust to inclusion of variables that might affect results. Taking into account that larger firms are also older firms, results show that inclusion of firm age does not alter the positive effect of firm size on wages.

Multinationals, cross-border acquisitions and wage dispersion

We examine the impact of cross-border acquisitions on intra-firm wage dispersion using a detailed Swedish linked employer-employee data set including data on all firms and about 50% of the Swedish labour force with information on job-tasks and education. Foreign acquisitions of domestic multinationals and local firms increase wage dispersion but so do also other types of cross-border acquisitions. Hence, it is the acquisition itself rather than foreign ownership that increases wage dispersion. The positive wage effect is concentrated to CEOs and other managers, whereas other groups are either negatively affected or not affected at all.

Multinational Firms and Job Tasks

We analyze the impact of multinational and foreign ownership on the demand for job tasks and educational skills. By using Swedish matched employer-employee data, we find that both foreign and domestic multinational firms have high shares of non-routine tasks and tasks requiring personal interaction. Moreover, acquisitions of local firms by multinationals increase the relative demand for non-routine and interactive job tasks in the targeted firms. The differences in the demand for job tasks are only partly explained by firm characteristics. Dividing employees by education instead of job tasks does not result in the same effects on relative labor demand, which shows that task measures do indeed capture a new labor market aspect.

Competition, Takeovers and Gender Discrimination

Theories of taste-based discrimination predict that competitive pressures will drive discriminatory behavior out of the market. Using detailed matched employer-employee data, we analyze how firm takeovers and product market competition are related to the gender composition of the firms workforce and the gender wage gap. Using a difference-in-difference framework and dealing with several endogeneity concerns, we find that the share of female employees increases as a result of an ownership change, in particular when product market competition is weak. Further, increased competition reduces the gender wage gap, especially among highly educated employees. While the estimated wage effect is quite small, the results support the main theoretical predictions.

Employment Protection Reform, Enforcement in Collective Agreements and Worker Flows.

Differential enforcement of employment protection by explicit design of the legislation, for example through exemptions for small firms, has been exploited in a growing body of research. However, little is known about the effects of differential enforcement that is not defined by the letter of the law, presumably due to the lack of data. Our study incorporates aspects of both types of differential enforcement as we combine the evaluation of a partial reform with information on the more difficult-to-observe enforcement of the same reform in collective agreements. We analyse a reform of notice periods for employer-initiated separations in Sweden, which reduced the notice periods for newly hired older workers substantially but implied minor or no changes in the notices for younger workers. The reform was initiated at different times depending on collective agreement. These circumstances provide ample opportunity for the identification of its effects. Our findings indicate heterogeneous effects across collective agreements. Despite differences in terms of dynamics and size, a positive effect on hirings is found for all agreements. In most cases, our results also show an increase in separations, indicating an increase in employment turnover. A salient feature of the results is that the estimated effects increase with the treatment dose, i.e., the size of the reduction in notice periods across different age groups.

The Dynamics of Offshoring and Institutions

Abstract Previous research has found that weak institutions can hamper investment and alter patterns of trade. However, little is known about the impact of institutional quality on offshoring. This lack of knowledge is surprising, given that offshoring has become an important part of many firms’ internationalization strategies. This study uses detailed firm-level data for the 1997–2005 period to examine the relationship between institutional quality in 113 source countries and offshoring by Swedish firms. The results suggest that weak institutions are negatively related to offshoring in general and to the offshoring of R&D- and relationship specificity-intensive inputs in particular. An analysis of learning effects suggests that the impact of weak institutions on the offshoring of relationship specificity-intensive inputs vanishes when firms return to countries from which they have previous market experience. Our results are robust to the use of various measures of institutional quality.

Global Engagement, Complex Tasks and the Distribution of Occupational Employment

Building on a framework introduced by Chaney and Ossa (2013), we construct a task-based model of the firm’s choice of occupational inputs to examine how that choice varies with greater global engagement. We depart from Chaney and Ossa by assuming that more complex tasks are more costly to complete. Within the structure of our model, firms skew employment toward occupations engaged in more complex tasks. Moreover, the distribution of employment is more skewed for more globalized firms, while it is less skewed for larger firms. These results are consistent with our empirical findings in Davidson, et al (2015).

Foreign Direct Investment, Source Country Heterogeneity and Management Practices

This paper examines whether and, if so, why source country heterogeneity exists in foreign direct investment (FDI). Using detailed data on all Swedish firms for the period from 1996 to 2009, we find statistical evidence that affiliate performance differs systematically across source countries. For instance, affiliates of US multinational enterprises (MNEs) are, on average, approximately three times more productive than affiliates headquartered in the Nordic countries. One possible explanation for these discrepancies is differences in organization practices across source countries. Using new firm-level data from the World Management Survey to estimate a global index of the quality of management practices for MNEs with headquarters in our source countries of interest, we find that source country heterogeneity in affiliate performance is highly correlated with differences in management practices.
