Chebbi, H. and Olarreaga, M. (2019). Investigating exchange rate shocks on agricultural trade balance: The case of TunisiaThe Journal of International Trade and Economic Development.

Abstract: The paper studies the impact of changes in Tunisia’s exchange rate on the net external position of the agricultural sector. It shows that substitutability on production and consumption among domestically produced goods leads to an ambiguous impact for reasons that go beyond the Marshall-Lerner condition. Using cointegration techniques to disentangle the long and short-run impact of changes in the exchange rate on the net agricultural trade balance, we find that the depreciation of the domestic currency leads to a deterioration of the net external position of Tunisia’s agricultural sector in the long-run.

Guizani, B. (2019). The Impact of Exchange Rate Shocks on Trade in Times of Uncertainties: Evidence from Three Oil-Importing Countries in MENA, forthcoming in Statéco, No 113.

 

Abstract: On the basis of a monthly data relating to trade flows, nominal exchange rates and other economic variables and a VAR model framework, some impulse-response functions (IRFs) are estimated for three Oil-Importing Countries (OICs) of the MENA region. These IRFs were estimated for two sub-periods notably the periods of political transition in these countries that were characterized by high degrees of uncertainty. The main finding is that unlike what many might expect, during the periods of transitions a shock in the exchange rate has a very weak impact of the levels of exports and imports in all three countries. It is therefore concluded that the deteriorating international competitiveness of the OICs especially throughout the transition is related to other structural factors rather than the exchange rate.

Abstract: This paper analyzes the effect of nontariff measures (NTMs) on firms in Tunisia. It draws a precise picture of NTMs’ effects on firms’ imports. We use firm‐level data to take into account firm heterogeneity. We explore the impact of NTMs on small vs. medium and large firms. We also consider the differentiated impact of NTMs. Some measures have informational content and help reduce information asymmetries. When the endogeneity issue of NTMs is controlled for, results show an overall positive impact of NTMs on imports. They provide evidence that NTMs are more beneficial to the imports of medium and large firms. Moreover, NTMs with informational content have an import enhancing effect. An extended analysis separating importing and exporting firms from those solely importing suggests that both types of firms benefit from the positive effects of NTMs. This result highlights the need to assist small firms facing NTMs. Furthermore, some NTMs with informational content should be addressed carefully and not considered only as barriers to trade to be eliminated. Instead, harmonization efforts between countries can be a better policy.

Abstract: In this paper, we contribute to the literature by studying the effect of internationalization on the conditional firm growth rate distribution in eight countries from the MENA region. We use four measures of internationalization: exporting status, two-way trade, export intensity and export experience. We use the BEEPS data from the Enterprise Survey of the European Bank for Reconstruction and Development and the World Bank. The main results show that exporting status and export experience play an important role to improve both employment and sales growth in various quantiles. However, two-way trade has an effect on employment growth and export intensity has an effect on lower sales growth quantiles.
