Trade liberalization and demand labor elasticities : evidence from Tunisia

Ce papier étudie les effets de la libéralisation des échanges sur les élasticités de la demande du travail. Une équation de demande d'emploi est estimée en se fondant sur des données (1971-1996) portant sur six industries manufacturières tunisiennes. Les résultats des tests économétriques ne vérifient pas l'idée que la libéralisation des échanges peut permettre une augmentation de l'élasticité de la demande du travail. Dans la majorité des industries considérées, l'hypothèse de l'absence d'une relation entre l'ouverture commerciale et l'élasticité demande de travail ne peut pas être rejetée. La faiblesse de l'élasticité de demande de travail peut être expliquée par les régulations du marché du travail mises en place durant 1987-1996. Cependant, les résultats sont robustes par rapport au type de statut du travail considéré (main-d'oeuvre contractuelle et permanente). Ces résultats confortent l'idée qu'au cours de la période de libéralisation, le marché du travail est devenu plus flexible, et que les chefs d'entreprise préfèrent embaucher des travailleurs contractuels. This paper investigates the effects of trade liberalization on labor demand elasticities. Employment demand equation is estimated by using data (1971-1996) for manufacturing industries in Tunisia. Results from empirical testing using the model find a weak support for the idea assuming that trade liberalization will lead to an increase in labor demand elasticities: in the vast majority of the industries we consider, we cannot reject the hypothesis of no relationship between trade openness and labor-demand elasticities. This weakness of labor demand elasticity in practice is perhaps explained by the tight labor market regulations in place during the 1987-96. However, our results are robust to the type of labor considered (contract labor and permanent labor). This supports the conclusion that under liberalization period labor markets have become more flexible, and that employers prefer recruiting contracts worker. (Full text in english)

Economies of Scale in the Tunisian Industries

To date, empirical investigations of trade liberalization under the conditions of increasing returns to scale (IRS) and imperfect competition (IC) have either assumed or imposed the market and productive structures necessary for such a model. However, of the recent IRS/IC models used to simulate the effects of trade liberalization none have empirically tested for the presence of increasing return to scale prior to the analysis. With Tunisian data (1971-2004) and rigorous test procedures, we investigate evidence of IRS at the industry level. Using an econometric approach based on the estimation of the translog cost function and its associated cost share equations, we identify the sectors characterized by increasing returns to scale. Analysis of the results shows that specification of the model is sensitive to inclusion of time trend representing technology. The model accounting for technology did not fit the data well for most sectors. The estimation results without time trend interactions are different. Here most of the sectors show signs of increasing returns to scale.economies of scale, trade liberalization, new trade theory, Tunisian industries, cost functions

Consequences of trade liberalization on the labor market in developing economy : The case of Tunisia

This paper investigates short and long run effects of trade liberalization on employment and wages using a specific factor trade model. Employment and wage equations areestimated using data (1971-1996) for importable and exportable sectors in Tunisia. Results fromempirical testing using the model find some supports for the theoretical predictions of Edwards(1988) for the exportable sector. On the other hand, in the importable sectors, we find resultsthat are opposed to those predicted by Edwards (1988) since employment and wages increase. Apossible reason for the divergence of theory and practice is that the Edward's model is premisedon the basis of a fixed supply of labour. Exportable employment could therefore only rise ifimportable employment fell. However, as we have seen, the supply of labour increaseddramatically in Tunisia as women entered the labour market. This allowed employment inimportable to be maintained (even slightly increase) as the exportable sector expanded.

Labour-Use Efficiency in the Tunisian's Manufacturing Industries: A Flexible Adjustment Model

This paper investigates the process of adjustment in employment. A dynamic model is applied to a panel of six Tunisian manufacturing industries observed over the period 1971-1996. The adjustment process is industry and time specific. The adjustment parameter is specified in terms of factors affecting the speed of adjustment. Industries are assumed to adjust their labour inputs towards a desired level of labour-use. A translog labour requirement function is specified in terms of observable variables and is used to model the desired level of labour-use.The labour requirement is specified to be function of wages, output, quasi-fixed capital stock and technology. The empirical results show that in the long-run, employment demand responds greatest to value added, followed by capital stock changes, and least by wages. The speed of adjustment in employment and the degree of labour-use efficiency show large variations among thesectors and over time.

The Impact of Arab Spring on Hiring and Separation Rates in the Tunisian Labour Market

This paper analyses the hiring and separation rates in Tunisia before and after the Arab Spring of 2011. Several models are specified to study employment decisions based on quarterly administrative firm level data over the period of 2007 to 2012. The data provides information about important firm characteristics such as industry sector, number of hiring and separation, total employment effects and composition of labour force by gender, managerial level and age cohorts. Six models are estimated to investigate hiring, separation, hiring rate, separation rate, mobility, and net-employment. The results indicate presence of continued risk factors in Tunisia's labour market resulting from the global financial crisis in 2008 and the Arab Spring in 2011. Hiring was little changed during this time period, and the results suggest that factors that impact separation decisions remained present in Tunisia's labour market. In addition, the paper looks at various social issues such as youth unemployment and infer on how more efficient policy actions that will further engage the private sector could result in more sustainable positive net-employment and increased labour mobility

The Effects of Union Wage-Settings on Firms' Production Factor Decisions

This study is concerned with the development of a theoretical model and its empirical application to the estimation of the interaction between firms and trade union in determining wages and employment. The focus is on analyzing the effects of unions? demands on the firm?s choice of factors of production. In a two-step process the union and firm determine wages and capital stock, conditional on which the firm decides on production factors of employment, working hours and capital operating time. We suggest the use of a panel data approach applied to manufacturing data. A dynamic model is specified in which the optimal levels of the variables of interest and the speed of their adjustments are modeled in terms of observable policy variables

Can the UAE Avoid the Oil Curse by Economic Diversification?

Recent research conclude that the GCC economies have failed to address the oil curse. They are far behind other countries, especially those in the G7, which possess huge reserves of oil wealth but have undertaken economic diversification to correct the ill-effects of an oil curse. This paper takes an in-depth look into the UAE economy as a model but also as a reminder of the struggles ahead. The findings support the fact that the UAE is facing an oil curse. Declining levels of total factor productivity, GDP volatility, negative returns on investment, and a labor force that is too reliant on government's supply of jobs are among the many reasons that support the thesis. The UAE has made good progress in recent years to diversify its economy. However, the drivers of economic growth in the UAE are vulnerable to external shocks outside of the Emirate's control. It is now critical that the UAE take steps to mitigate economic disruptions that might result from these shocks. In this case study the UAE economic performance is examined, and a data-driven roadmap for sustainable growth is suggested. The analysis shows that greater efforts are needed to stimulate the diversification of the production base by encouraging increased domestic, especially private, investment. Well-targeted policies should be adopted to accelerate reform and facilitate the involvement of the private sector in the economy
