Lessons from the Eurobarometer 2007: Insights on Undeclared Work in Belgium

This analysis offers an in-depth look at the Eurobarometer's findings on undeclared work (UDW) in Belgium, exploring puzzling results and the effectiveness of econometric treatment. It discusses the dimensions of UDW, including demand for services and the impact of individual characteristics. The preliminary results identify key actors' attributes and emphasize the importance of national perceptions and institutional trust. The paper highlights limitations in sample size and cases while proposing a new survey targeting UDW specifics in Belgium.

Presentation Transcript

  1. Lessons from the Eurobarometer 2007 Additional analysis from the Belgian perspective Sergio Perelman CREPP, HEC-Ecole de Gestion, Université de Liège

  2. Outline • The Eurobarometer on UDW • Puzzling results • The limits of descriptive analysis • Econometric treatment • Lessons from the Eurobarometer • A new survey in Belgium

  3. The Eurobarometer on UDW • A first international large scale attempt • UDW dimensions retained - Demand of services/products - Supply: UDW as part of salary Other undeclared activities • Individual characteristics and perceptions • An invaluable tool for research purposes

  4. Puzzling results UDW and refusal rates NORDIC: DK, FI, SE CONTINENTAL: AT, BE, DE, FR, LU, NL + UK + IE SOUHTERN: CY, EL, ES, IT, MT, PT EASTERN: BG, CZ, LV, LT, HU, EE, PL, RO, SI, SK

  5. Puzzling results Sample representativity Belgium: Population aged 15+

  6. Puzzling results Perceptions and institutions

  7. Puzzling results Respondents’ cooperation

  8. The limits of descriptive analysis % UDW Other activities

  9. The limits of descriptive analysis % UDW Part of salary

  10. Econometric treatment • Probit/Logit Models • UDW participation (Demand/Supply) • Explanatory variables - age, sex, education, family size, origin - occupation, economic sector - urban/rural areas, house ownership • Control variables - country dummies - perceptions, respondents’ cooperation

  11. Econometric treatment ***, **, *: 1%, 5% and 10% Khi2 Test significativity

  12. Econometric treatment Undeclared work: Demand of services or products ***, **, *: 1%, 5% and 10% Khi2 Test significativity

  13. Econometric treatment Undeclared work: Part of salary ***, **, *: 1%, 5% and 10% Khi2 Test significativity

  14. Econometric treatment Undeclared work: Other activities ***, **, *: 1%, 5% and 10% Khi2 Test significativity

  15. Lessons from the Eurobarometer • Preliminary econometric results - Allowing to identify several actors’ characteristics - Demand and supply driven by country specificities - Perceptions on national institutions mater - Robust results • Drawbacks - Too small country sample size - Limited UDW cases to be analyzed

  16. A new Survey on UDW in Belgium • Sample design - Depending on demand and supply specificities studied - For instance, supply of UDW • Over sampled characteristics - Construction, repair services, transport, hotels/restaurants - Men aged less than 55 years old - Occupations other than employees
