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

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.

Labour Market Power and Between-Firm Wage (In)Equality

IWH-CompNet Discussion Papers,
Nr. 1,
2020
Abstract
This study investigates how labour market power shapes between-firm wage differences using German manufacturing sector data from 1995 to 2016. Over time, firm- and employee-side labour market power, defined as the difference between wages and marginal revenue products of labour (MRPL), increasingly moderated rising between-firm wage inequality. This is because small, low-wage, low-MRPL firms possess no labour market power and pay wages equal to or even above their MRPL, whereas large, high-wage, high-MRPL firms possess high labour market power and pay wages below their MRPL. These wage-MRPL differences grow over time and compress the firm wage distribution compared to the counterfactual competitive labour market scenario. Particularly for the largest, highest-paying, and highest-MRPL firms, wage-MRPL differences strongly increase over time. This allows these firms to generate increasingly large labour market rents while being active on competitive product markets, providing novel insights on why such “superstar firms” are profitable and successful.

Why Is there Resistance to Works Councils In Germany? An Economic Perspective
Steffen Müller, Jens Stegmaier
Economic and Industrial Democracy,
Nr. 3,
2020
Abstract
Recent empirical research generally finds evidence of positive economic effects for works councils, for example with regard to productivity and – with some limitations – to profits. This makes it necessary to explain why employers’ associations have reservations about works councils. On the basis of an in-depth literature analysis, this article shows that beyond the generally positive findings, there are important heterogeneities in the impact of works councils. The authors argue that those groups of employers that tend to benefit little from employee participation in terms of productivity and profits may well be important enough to shape the agenda of their employers’ organization and have even gained in importance within their organizations in recent years. The authors also discuss the role of deviations from profit-maximizing behavior like risk aversion, short-term profit-maximization and other non-pecuniary motives, as possible reasons for employer resistance.

Cross-country Evidence on the Relationship between Regulations and the Development of the Life Insurance Sector

2020
Abstract
Using a global sample, this study sketches the impact of insurance regulations on the life insurance sector, revealing a significant negative association between supervisory control on policy conditions of life annuities as well as pension products and the development of the industry. A similar inverse relation is observed between the index of capital requirements and insurance development. These results hold when we control for demographic factors, economic factors, religious inclination, culture, as well as for other relevant regulations. We also find some evidence that while the overall supervisory power does not matter, the ability to intervene at an early stage could have a positive effect on insurance development. Additionally, the impact of some regulations appears to differ between advanced and developing countries.

The Cleansing Effect of Banking Crises

Nr. 12,

Abstract
We assess the cleansing effects of the recent banking crisis. In U.S. regions with higher levels of supervisory forbearance on distressed banks during the crisis, there is less restructuring in the real sector and the banking sector remains less healthy for several years after the crisis. Regions with less supervisory forbearance experience higher productivity growth after the crisis with more firm entries, job creation, and employment, wages, patents, and output growth. Supervisory forbearance is greater for state-chartered banks and in regions with weaker banking competition and more independent banks, while recapitalisation of distressed banks through TARP does not facilitate cleansing.

Worker Participation in Decision-making, Worker Sorting, and Firm Performance
Steffen Müller, Georg Neuschäffer
IWH-Diskussionspapiere,
Nr. 11,
2020
Abstract
Worker participation in decision-making is often associated with high-wage and high-productivity firm strategies. Using linked-employer-employee data for Germany and worker fixed effects from a two-way fixed effects model of wages capturing observed and unobserved worker quality, we find that establishments with formal worker participation via works councils indeed employ higher-quality workers. We show that worker quality is already higher in plants before council introduction and further increases after the introduction. Importantly, we corroborate previous studies by showing positive productivity and profitability effects even after taking into account worker sorting.

Abstract
As we enter a second phase of the COVID-pandemic, in which we attempt to reopen economies and foster growth, investigating the efficiency and productivity of firms becomes essential if we wish to design the appropriate policies. The 2020 Flagship Firm Productivity report provides a comprehensive account of how productivity is changing –and what is driving those changes –in Europe, drawing from granular firm-level information.Although it was written before the crisis erupted, this report can therefore offer critical insights to current policymaking andprovides grounds for future research.
