Title: Quantifying the productivity counterpart of outsourcing in the Italian manufacturing industries


1
Quantifying the productivity counterpart of
outsourcing in the Italian manufacturing
industries
  • F. Daveri - M. Iommi - C. Jona-Lasinio
  • OECD Productivity Workshop
  • Bern, 16-18 October, 2006

2
Motivation
  • Growing importance of international outsourcing
    of services in Western economies.
  • Evidence that both offshoring of services and of
    material inputs are associated with productivity
    gains
  • Amiti and Wei, 2006 Girma and Gorg, 2004
    Criscuolo and Leaver, 2005.
  • Outsourcing as such, irrespective of where to,
    should be associated to productivity growth
  • Italy was largely missing from previous research
    on this topic.
  • Availability of new symmetric I-O tables.

3
Our aims
  • Quantify the extent of domestic and international
    outsourcing in the Italian manufacturing sector.
  • Provide a comparison between direct and indirect
    measures of outsourcing.
  • Evaluate the productivity counterpart of
    outsourcing.

4
Data
  • Symmetric input-output tables (industry by
    industry matrix)
  • At the 60-sector level (according to the NACE
    Rev1.1 classification)
  • Time period 1995-2003
  • Focus on domestic and international outsourcing
    of manufacturing intermediates and services for
    14 manufacturing industries
  • Our broad - definition of market service
    providers
  • transports, storage and communications
  • finance and insurance
  • real estate and other business services

DIJ vs FH measures
  • FH measure imputes average propensity to import
    for the economy to each industry unwarranted
    assumption justifed by data limitations
  • We have the right data to directly compute
    offshoring
  • FH and DIJ measures are highly correlated
  • Across industries r is 0.8 on average 1995-03
    (but falls to .6 in
  • 1999-03)
  • FH shares systematically lower than DIJ shares
  • Feenstra-Hanson measures systematically
    optimistic in evaluating extent of offshoring
  • Use of indirect outsourcing measures may bias
    estimates

Conclusions and future research
  • Not all manufacturing industries outsource
    production to the same extent either inside or
    outside the country
  • Off-shore outsourcing took off in 1999-2003, not
    before
  • Only the international outsourcing of
    intermediates is positively related to
    productivity growth, while the other forms of
    outsourcing are not robustly related to
    productivity growth

16
Conclusions and future research
  • Direct and indirect measures of outsourcing
    provide different empirical results
  • The results obtained from our indicator of
    outsourcing are quite different from those
    arising from the commonly used Feenstra-Hanson
    measures of outsourcing

17
Conclusions and future research
  • Disaggregate market services further
  • Potential to do so I-O Table available with up
    to 101 industries
  • Improve econometric techniques to more
    satisfactorily deal with endogeneity issues
