  1. Does Outsourcing to Central and Eastern Europe really threaten manual workers’ jobs in Germany? Ingo Geishecker Juni 2005

  2. Outline • Stylised facts: Skill upgrading in manufacturing • International Outsourcing • The literature • The econometric model • Estimation

  3. Motivation: Wage and employment trends Unskilled worker‘s employment • Germany: continued rise in unemployment of low-skilled workers • skill upgrading of employment Unskilled workers‘ earnings • relative wages close to stable

  4. Unskilled employment

  5. 25% 20% no Training 15% 10% Average Vocational Training 5% University/Technical College 2000 1975 1980 1985 1990 1995 Unskilled unemployment Source: IAB calculations

  6. Shift-share analysis change in cost share of low-skilled labour in total wage bill decomposed into change in relative wages and change in relative employment: - 23%-pts = - 2%-pts - 21%-pts confirms Literature on stable relative wages and relative fall in low-skill employment

  7. Shift-share analysis change in employmentshare of low-skilled labour decomposed into within-industry and cross-industry skill upgrading: - 3.2 %-pts = - 3.9 %-pts + 0.7 %-pts summarising: skill upgrading occurs within and not across industries under nearly constant relative wages Question: What drives skill upgrading?

  8. Theory of outsourcing and labour demand • General equilibrium models • Feenstra Hanson (1996) • Jones and Kierzkowski (2001) • Arndt (1999) • Kohler (2003) • How outsourcing effects demand for low-skilled labour in general equilibrium is not clear. • Empirical question. But first can we even find effects of outsourcing in partial equilibrium?

  9. Empirics of fragmentation and wages • industry level studies: • Feenstra and Hanson (1996), Morrison-Paul and Siegel (2001) and others: composite demand equation for low-skilled labour, outsourcing is shift parameter • problem: aggregation bias, endogeneity bias, measurement • Falk and Koebel (2002): use relative prices and no shift parameter • problem: outsourcing only captured by relative price changes • micro level studies: • Geishecker, Görg (2004) on outsourcing and wages

  10. International Outsourcing Use trade data, allocate imports to domestic industries by utilising input-output data • wide definition: all imported inputs of an industry i • narrow definition: international Outsourcing is outcome of a “make or buy” decision, hence only imported inputs from the same industry i abroad are relevant

  11. International Outsourcing by region Differentiate import data by geographic region (as in Anderton and Brenton, 1999) , allocate to industries holding use coefficient constant • wide definition: • narrow definition:

  13. Wide Outsourcing by geographic region Source: OECD commodity trade data, Statistisches Bundesamt Input-Output Tables, authors calculations

  14. Empirical Model • Potential endogeneity of relative Wage and Outsourcing • GMM using one and two year lagged values • GMM is consistent but not efficient • therefore endogeneity tests first

  20. Summary • substantial within industry skill upgrading • nearly constant relative wages • in the narrow outsourcing model the predicted overall decline in manual workers wage bill share is 4.7 %-pts • of this, increasing outsourcing can explain 2.7 %-pts • technological progress can explain almost 3 %-pts • with nearly constant relative wages, decline in relative demand has to be met by reductions in relative employment • Therefore: manual workers jobs are indeed threatened by outsourcing towards CEC
