Identifying High-Growth Enterprises in Italy: A Workshop Recap

This workshop focused on identifying high-growth enterprises in Italy using specific criteria and analysis methods. The process involved comparing distributions of active and potential populations, setting growth thresholds, and identifying HG enterprises by growth rate and events. It also explored the concept of gazelles and alternative measurement bases, such as the Birch index.

  1. OECD WORKSHOP ON THE MEASUREMENT OF THE HIGH-GROWTH ENTERPRISES THE IDENTIFICATION OF HG ENTERPRISES The Italian case Paris, November 19, 2007

  2. Identification of HG Let Nxx be the active population in year xx, reference year (xx=2005) Step1: a merge by identification code of the population Nxx and Nxx-1 to xx-3 → AA=N2002 ∩ N2003 ∩ N2004 ∩ N2005 Step2: we exclude the real births in xx-3 i.e. Rb(2002) from AA, then Poten_population=AA-Rb(2002)

  3. Comparing distributions Potential population AA versus Active population N By size class Dissimilarity index : Nxx versus AA Calculated by nace&size

  4. Potential population AA

  5. Size threshold : 10 or more employees in the beginning Step3: If employees(2002) ≥ 10 → reference for HG =140,401 for year 2005 Growth threshold : 20% per annum Step4: HG are obtained applying to the population of reference (step 3) the following rules to employees and to turnover: HG_empl - yes IF [empl(2005)/empl(2002)] ≥ 1.728 HG_tur - yes IF [turnover(2005)/turnover(2002)] ≥ 1.728

  6. Growth measured by employees or turnover Ratio= HG/pop_ref_hg= 14033/140401 *100= 10.0%

  7. HG by type of growth (employees or/and turnover) by sector of activity (%)

  8. Growth by events Step5: HG can grow because events of takeover. Takeover from units that cease Takeover from units that transfer activity Looking for such events in the period 2002-2005, we have identified 979 (7%) of HG with events. By excluding such events we obtain the “pure” HG, HG*= 13054 Ratio*= HG*/pop_ref_hg= 13054/140401 *100= 9.3%

  9. HG: with or without events?(1) HG with events and “pure HG”, by sector of activity (%)

  10. HG: with or without events?(2)

  11. HG : Turnover and employment Growth rates by size and sectors

  12. Gazelle It is that subset of HG that are real births in xx-5 and xx-4. For xx=2005 gazelles are obtained by merging the real births 2000 and the real births 2001 with HG by identification code Step1: potential gazelle are identified as the potential population of HG born in 2000 and 2001 (the subset of real births in 2000 and 2001 surviving in 2005, with employees(2002) ≥10)

  13. Gazelle

  14. Working in progress Changing Growth threshold

  15. Working in progress Alternative bases for measurements Varying threshold of growth BIRCH index m=(xt1-xt0) xt1/xt0 where xt1=employees(2005) xt0=employees(2002) HG by Birch are: the AA having m>=m[90%] OR m>=m[95%] of the distribution in the whole economy

  16. Working in progress Problem: which base to be used as reference population? AA size [1+] ? AA=902068

  17. Working in progress Comparison between HG and Birch top 10%
