Negli anni ’80, paesi in via di sviluppo (DCs) e paesi meno sviluppati (PMS) hanno subito cambiamenti strutturali, muovendosi da politiche di sostituzione di importazione a strategie di liberalizzazione. Questi paesi hanno assistito ad una crescita dinamica risultata dall’aumento della produttività dovuto alla maggiore esposizione delle industrie locali alla concorrenza, dall'aumento delle importazioni tecnologiche incarnate in capitale e in beni intermedi, e ad una maggiore diffusione di conoscenze e informazioni. Questo lavoro esamina come liberalizzazione commerciale ed aggiornamento tecnologico abbiano influito sull’occupazione in paesi DCs e PMS, e studia il fenomeno del cambiamento tecnologico skill biased. Si esaminano il settore manifatturiero turco tra il 1980-2001 e quello etiope tra il 1996-2004. Questo studio, basato sul System Generalized Method of Moments (GMM-SYS), implementa un quadro dinamico di due equazioni che raffigurano tendenze occupazionali a livello enterprise per lavoratori qualificati e non qualificati. I risultati confermano l'aspettativa teorica che DCs e LDC affrontano fenomeni di skill-biased technological change e incrementano il potere d’importazione di tecnologia, aumentando il divario d’occupazione tra lavoratori qualificati e non qualificati. Tuttavia, le cause specifiche di skill-bias e la portata del loro effetto possono variare in base a diverse infrastrutture istituzionali e capacità nazionali.

Abstract
In the 1980's developing countries (DCs) and least developed countries (LDCs) underwent structural changes, moving from import substitution policies to liberalization strategies. These countries witnessed a dynamic growth effect that emerges from productivity growth due to increased exposure of local industries to competition, increased technological imports embodied in capital and intermediate goods, and to the transfer of knowledge. This work looks into the employment impact of trade liberalization and technological upgrading in DCs and LDCs, and studies the phenomenon of skill biased technological change in those countries. It takes the case of the Turkish manufacturing sector for the period 1980 - 2001, and the case of the Ethiopian manufacturing sector for the period 1996 - 2004. It deploys System Generalized Method of Moments (GMM-SYS) procedure to this effect, implementing a two-equation dynamic framework that depicts enterprise-level employment trends separately for skilled and unskilled workers. The results confirm the theoretical expectation that DCs and LDCs face the phenomena of skill-biased technological change and skill-enhancing technology import, both leading to increasing the employment gap between skilled and unskilled workers. However, the specific determinants of skill bias and the size of their effect can differ due to diverse institutional infrastructures and national capabilities.File | Dimensione | Formato | |
