Impact of trade liberalization on firm's labour demand by skill: The case of Tunisian manufacturing

This paper investigates the impact of the trade liberalization process in Tunisia on employment by distinguishing different skills and different types of firms using micro level data covering the period of 1983–1994. There is considerable disagreement among analysts on the impact of recent trade reforms upon labour. Our contribution to these debates in this paper is essentially an empirical issue. The analysis of a Tunisian firm's data may be viewed as an attempt to apprehend how employment in Tunisia, a developing country, adjusted to the trade reforms. Using micro-level detail on individual firms, we are able to trace the relationship between changes in trade policies and manufacturing employment at firm level and by skill. Although trade reforms are generally implemented at the sector level, their effects may vary significantly across firm characteristics such as output orientation. We measure the effects of trade policy on employment according to different types of firms. We also associate changes in employment directly with a measure of change in trade protection, rather than linking them to changes in imports and exports which would be more common. The results suggest that the impact of trade liberalization on labour demand depends on a firm's characteristics. In particular, the estimates obtained suggest that trade liberalization has beneficial effects on employment for exporting-firms. Conversely, trade liberalization has negative and disciplinary effects on employment for domestically oriented firms. The reduction in tariff levels conducted in this first phase of liberalization in Tunisia seems to have had effects with different intensity on unskilled labour and on skilled labour; this justifies the examination of these two skills.
