Labor-use Efficiency in Tunisian Manufacturing Industiries
Haouas, Ilham; Yagoubi, Mahmoud; Heshmati, Almas - In: Review of Middle East Economics and Finance 1 (2003) 3, pp. 1-20
This paper investigates the process of adjustment in employment. A dynamic model is applied to a panel of six Tunisian manufacturing industries observed over a period of 25 years, from 1971 to 1996. Industries are assumed to adjust their labor inputs toward a desired level. A labor requirement...
