Central Bank Independence & Coordinated Wage Bargaining: Their Interaction in Germany & Europe. CES Germany & Europe Working Papers, No. 04.4, 1994

This paper explores the fashionable proposition that with a more independent central bank, a country can secure lower levels of inflation without higher unemployment. Hall shows that the operation of the central bank depends on the character of wage bargaining. He illustrates this point with some cross-national data and an analysis of how coordinated wage bargaining is secured in Germany. He concludes by exploring the implications of this analysis for European Monetary Union.

Filling the gap: open economy considerations for more reliable potential output estimates. Bruegel Working Paper 2015/11, October 2015

This paper argues that the Phillips curve relationship is not sufficient to trace back the output gap, because the effect of excess demand is not symmetric across tradeable and non-tradeable sectors. In the non-tradeable sector, excess demand creates excess employment and inflation via the Phillips curve, while in the tradeable sector much of the excess demand is absorbed by the trade balance. We set up an unobserved-components model including both a Phillips curve and a current account equation to estimate ‘sustainable output’ for 45 countries. Our estimates for many countries differ substantially from the potential output estimates of the European Commission, IMF and OECD. We assemble a comprehensive real-time dataset to estimate our model on data which was available in each year from 2004-15. Our model was able to identify correctly the sign of pre-crisis output gaps using real time data for countries such as the United States, Spain and Ireland, in contrast to the estimates of the three institutions, which estimated negative output gaps real-time, while their current estimates for the pre-crisis period suggest positive gaps. In the past five years the annual output gap estimate revisions of our model, the European Commission, IMF, OECD and the Hodrick-Prescott filter were broadly similar in the range of 0.5-1.0 percent of GDP for advanced countries. Such large revisions are worrisome, because the European fiscal framework can translate the imprecision in output gap estimates into poorly grounded fiscal policymaking in the EU.

Wage inequality in Germany – What role does global trade play? Policy Brief #2015/03

Wage inequality in Germany has increased significantly since the mid-1990s. The intensification of international trade relations is a frequently cited cause for this issue. However, an empirical study revealed that global trade can only directly explain around 15 percent of the increase in wage inequality in Germany. Primarily, the growing heterogeneity among companies in Germany plays a greater role – especially within industries. The decline in collective bargaining is the primary company-specific driver of wage inequality. Nevertheless, protectionist measures would not be effective for achieving greater wage equality.

An Italian job: the need for collective wage bargaining reform. Bruegel Policy Brief ISSUE 2016/11 - JULY 2016

Highlights: Since the mid-1990s, Italy has been characterised by a lack of labour productivity growth, combinedwith a 60 percent growth in labour costs, 20 percentage points above euro-area average consumer price growth. As a consequence, Italy has become less competitive compared to its euro-area partners, the profitability of its firms has dropped and real GDP-per-capita has flatlined. • At the root of the substantial discrepancy between wages and productivity is Italy’s system of centralised wage bargaining which, in many ways, is designed without regard for the underlying industrial structure and geographical heterogeneity of the Italian economy.This has fostered perverse incentives and imbalances within Italy. • Collective wage bargaining, and in particular the determination of base salaries, should be moved from the national to the regional level for all contracts, in the public and private sectors.The Mezzogiorno,which might superficially be seen as losing out from this policy, would actually gain the most in competitiveness terms. • Furthermore, measures should be taken so that, in the long run, the Italian industrial structure evolves into a less fragmented small-company-based economy. This firm consolidation would likely expand the use of firm-level agreements and performance payments, and would improve Italy’s productivity and competitiveness overall.
