Explaining Wage Losses after Job Displacement: Employer Size and Lost Firm Rents

Daniel Fackler Steffen Müller Jens Stegmaier

in: Journal of the European Economic Association, im Erscheinen

Abstract

Why does job displacement, e.g., following import competition, technological change, or economic downturns, result in permanent wage losses? The job displacement literature is silent on whether wage losses after job displacement are driven by lost firm wage premiums or worker productivity depreciations. We therefore estimate losses in wages and firm wage premiums. Premiums are measured as firm effects from a two-way fixed-effects approach, as described in Abowd, Kramarz, and Margolis (1999). Using German administrative data, we find that wage losses are, on average, fully explained by losses in firm wage premiums and that premium losses are largely permanent. We show that losses in wages and premiums are minor for workers displaced from small plants and strongly increase with pre-displacement firm size, which provides an explanation for the large and persistent wage losses that have been found in previous studies mostly focusing on displacement from large employers.

Firm Wage Premia, Industrial Relations, and Rent Sharing in Germany

Boris Hirsch Steffen Müller

in: ILR Review, Nr. 5, 2020

Abstract

The authors use three distinct methods to investigate the influence of industrial relations on firm wage premia in Germany. First, ordinary least squares (OLS) regressions for the firm effects from a two-way fixed-effects decomposition of workers’ wages reveal that average premia are larger in firms bound by collective agreements and in firms with a works council, holding constant firm performance. Next, recentered influence function (RIF) regressions show that premia are less dispersed among covered firms but more dispersed among firms with a works council. Finally, in an Oaxaca–Blinder decomposition, the authors find that decreasing bargaining coverage is the only factor they consider that contributes to the marked rise in premia dispersion over time.

Transferability of Skills across Sectors and Heterogeneous Displacement Costs

Moises Yi Steffen Müller Jens Stegmaier

in: American Economic Review: Papers and Proceedings, Nr. 5, 2017

Abstract

We use rich German administrative data to estimate new measures of skill transferability between manufacturing and other sectors. These measures capture the value of workers' human capital when applied in different sectors and are directly related to workers' displacement costs. We estimate these transferability measures using a selection correction model, which addresses workers' endogenous mobility, and a novel selection instrument based on the social network of workers. Our results indicate substantial heterogeneity in how workers can transfer their skills when they move across sectors, which implies heterogeneous displacement costs that depend on the sector to which workers reallocate.

Organised Labour, Labour Market Imperfections, and Employer Wage Premia

Sabien Dobbelaer Boris Hirsch Steffen Müller Georg Neuschäffer

in: Tinbergen Institute Discussion Paper, Nr. 20, 2020

Abstract

This paper examines how collective bargaining through unions and workplace co-determination through works councils shape labour market imperfections and how labourmarket imperfections matter for employer wage premia. Based on representative Germanplant data for the years 1999{2016, we document that labour market imperfections arethe norm rather than the exception. Wage mark-downs, that is wages below the marginalrevenue product of labour rooted in employers' monopsony power, are the most prevalentoutcome. We further nd that both types of organised labour are accompanied by asmaller prevalence and intensity of wage mark-downs whereas the opposite holds for wagemark-ups, that is wages above the marginal revenue product of labour rooted in workers'monopoly power. Finally, we document a close link between our production-based labourmarket imperfection measures and employer wage premia. The prevalence and intensityof wage mark-downs are associated with a smaller level and larger dispersion of premiawhereas wage mark-ups are only accompanied by a higher premium level.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?

Matthias Mertens Steffen Müller

in: IWH-Diskussionspapiere, Nr. 14, 2020

Abstract

East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms.
