Abstract:The relationship between trade openness and economic growth has been extensively investigated yielding to mixed and inconclusive results. This might be attributed to the omission of the role of capital stock and labor in the trade-growth nexus. This paper examines the impact of trade openness on economic growth for Cote d'Ivoire over the period 1965-2014 in a multivariate framework including capital stock, labor and trade openness as regressors. It uses the Autoregressive Distributed Lag bounds test to cointegration and the Toda and Yamamoto Granger causality tests. The results show that trade openness has positive effects on economic growth both in the short and long run. Furthermore, they reveal a positive and strong complementary relationship between trade openness and capital formation in promoting economic growth.

This study investigates the determinants of private consumption expenditure in Cote d'Ivoire using time series data from 1970 to 2016. The Autoregressive Distributed Lags bounds testing approach to cointegration is employed to depict the presence of a long run relationship between private consumption and its determinants and an error correction model is estimated to derive short run dynamics. The results show the presence of a long run relationship among the selected variables. In the long run, current income, wealth and government consumption expenditure play a positive role in determining private consumption, with the effect of current income being higher. Furthermore, consumption expenditure is negatively affected by inflation rate and real interest rate on deposits. In the short run, only income and wealth appear to have positive effects on private consumption while the effects of government consumption, inflation and interest rate were found to be insignificant. This study provides evidence for government to improve the level of private consumption.

JEL Classification: C32, E44. AbstractThe relationship between saving and investment has been sharply debated in the empirical literature following the pioneering work of Feldstein and Horioka (1980). This paper contributes to this literature. As opposed to most previous studies, which have used panel estimation methods, we test for cointegration and causality between saving and investment in time-series settings for the UEMOA member countries by using the bounds test for cointegration proposed by Pesaran et al. (2001) and the Granger causality test of Toda and Yamamoto (1995). The results show that domestic saving plays an active role in financing investment in only three countries. For the other four countries, the domestic savings rate and investment rate are not related.
