2. Introduction – Model – Estimation – Empirical Results – Conclusion Motivation: Entry Restrictions and Productivity How do entry restrictions affect intersectoral factor reallocation when open economies are hit by global industry shocks? - Multi-sector world equilibrium model where countries put upper bound on entry of new varieties. - Implies that in response to global sectoral shocks there is less factor reallocation in economies with tighter restrictions compared to frictionless benchmark. - Test this prediction in 1980s and 1990s using 2 proxies for frictionless benchmark reallocation.

3. Introduction – Model – Estimation – Empirical Results – Conclusion Existing Theoretical Literature Entrycosts economic efficiency - Technology adoption (e.g. Parente and Prescott, 1994) - Industry efficiency (e.g. Hopenhayn, 1992) - Product variety (e.g. Dixit and Stiglitz, 1978) - Market power (e.g. Stigler, 1971). - Entrepreneurship and employment (e.g. Pissarides et al., 2001) Focus here - Interaction between entry restrictions/delays and economic shocks - Examine link: entry restrictions/delays  intersectoral factor reallocation Ciccone Papaioannou:Entry Regulation and Intersectoral Reallocation

6. Introduction – Model – Estimation – Empirical Results – Conclusion Set-Up, Preferences, and Technology - Continuum of countries and sectors (each mass=1). - Each sector is made up of freely traded varieties, differentiated by country of origin. - Range of available varieties is endogenous. - Symmetric Cobb-Douglas preferences across industries (equal expenditure shares across industries). - Symmetric Constant-Elasticity-of Substitution within industries (substitution elasticity = e > 1). - Labor only production factor - To produce q of a variety, firms need z=q/A production workers and 1 overhead worker. - There is heterogeneity in productivity A across countries, sectors, and varieties.

8. Introduction – Model – Estimation – Empirical Results – Conclusion Market Structure and Equilibrium - Each firm produces a distinct variety and sets price to maximize profits. - Goods markets clear internationally. - Wages adjust to clear national labor markets. Labor supply is inelastic and constant in time. Ciccone Papaioannou:Entry Regulation and Intersectoral Reallocation

19. Introduction – Model – Estimation – Empirical Results – Conclusion Proxies for Frictionless Employment Reallocation in Response to Global Shocks • Benchmark-country approach: use data from a country with low levels of entry regulation, where employment growth is unlikely to reflect frictions in product (or labor or capital) markets (Rajan and Zingales, 1998).  Idiosyncrasies of benchmark country introduces measurement error.  ME does not necessarily take the “classical form.” • Global estimation approach: estimate global employment reallocation in a frictionless economy using data on all countries and accounting for the fact that in countries with high barriers to entry (or other institutional frictions) employment reallocation might not reflect industry shocks (Ciccone and Papaioannou, 2006).  Does not reflect idiosyncrasies of any country.  Must be treated as a generated regressor. (Consistency of estimates under quite weak conditions. Valid standard errors somewhat more complicated. See Wooldridge 2002.) Ciccone Papaioannou:Entry Regulation and Intersectoral Reallocation

21. Introduction – Model – Estimation – Empirical Results – Conclusion Data • Country-Industry Level (from UNIDO) - Log change in employment (in the eighties and nineties). - 55-45 countries; 27-28 manufacturing industries (more than 1,000 obs.) • Country-Level - Entry restriction indicators from Djankov, La Porta, Lopez-de-Silanes and Shleifer (2002); focus on time to start business (model emphasis on delays) - Other controls (labor market regulation, financial development, income) • Industry-level - US Employment growth - Global employment reallocation in a frictionless economy - Other industry measures (external finance dependence, sales growth, etc).

27. Introduction – Model – Estimation – Empirical Results – Conclusion Sensitivity Analysis-Robustness Checks • Differential effect of financial development for external finance dependent sectors (Rajan and Zingales, 1998) and sectors with good opportunities (Fisman and Love, 2007). • Positive effect of schooling level and schooling accumulation in spurring growth of skill-intensive sectors. • Controlling for income. • Alternative measures of entry restrictions.

28. Introduction – Model – Estimation – Empirical Results – Conclusion Conclusion Potential effect of entry restrictions on intersectoral factor reallocation? - Slow down the entry of new varieties and therefore intersectoral factor reallocation towards expanding industries. Do entry restrictions matter for intersectoral reallocation empirically? - Yes; countries where new businesses can be incorporated more quickly see faster employment growth in globally expanding industries.
