This study re-examines the Wagner's law of public expenditure for six sub-Saharan African countries while relaxing the assumption of a symmetric adjustment process underlying standard cointegration tests and error-correction models. The empirical methodology uses threshold cointegration tests to establish that there is a long-run relationship between government expenditure and per capita GDP for five countries, with income being positively related to public spending. Furthermore, the results of asymmetric Granger-causality tests provide support for Wagner’s law in the long run for five countries (Cameroon, Cote d’Ivoire, Ghana, Kenya, and Senegal), while the Keynesian view holds only in the short run for three countries (Benin, Cameroon, and Cote d’Ivoire). The short run evidence for two countries (Kenya and Senegal) support both Wagner’s law and Keynesian view.

In this study, we concern mainly about the short and long-run relationship between economic growth and financial development. We use a multi-steps methodology, namely the Autoregressive Distributed Lag (ARDL) approach and the Vector Error Correction Model (VECM) approach to test this relationship in Côte d’Ivoire from 1980 to 2014. Following our results, we conclude that there is a unidirectional causal relationship, both long run and short run, between GDP per capita and financial development index in Côte d’Ivoire running from economic growth to financial development.

The development of Ivorian public debt in recent years has raised concerns. Is its current level capable of boosting the economy or, on the contrary, being at the source of a recession? This paper analyzes the effect of the level of indebtedness on economic growth in Côte d’Ivoire using the Threshold Autoregressive (TAR) model over the period 1970-2018. The results obtained in the short run shed light on the no relationship between public debt and economic growth. In the long run, on the other hand, there is a bi-directional granger causality between public debt and the sustainability of economic growth. The non-linearity between the variables of interest has been studied and the results show the presence of a threshold effect: beyond 48.03 percent of GDP, any increase in public debt by 1% should reduce economic growth by 0.28%. Thus, the study questions the relevance of the criterion set by the WAEMU: public debt <70% of GDP.

There is a lack of consensus on the impact that population growth has on economic growth, even though this issue continues to be of utmost importance for policymaking, particularly in developing economies. This paper examines the causality between population growth and economic growth in Africa, using Johansen and Granger-causality models. Our results show that the variables are cointegrated, implying the existence of a long run relationship in Nigeria but not in Cote d’Ivoire. We also found a negative, long run causal relationship between the two variables in Nigeria: population growth negatively affects economic growth in the long term. In Cote d’Ivoire, our results show that population growth causes economic growth in the short run.

The aim of this article was to investigate empirically the link between financial development and economic growth in Cote d’Ivoire using time series data covering the period of 1970-2014, both in short and long run. The Error correction model and cointegration method were performed to capture the short and long run dynamics of this relationship respectively. The cointegration test result showed evidence of long-run and significant causal between financial development and economic growth in Cote d’Ivoire during the study period. Furthermore, the coefficient of the error correction term (ECT) in the short-run dynamic model was statistically insignificant with inappropriate sign and weak. Consequently, the empirical evidence suggests that countries authorities should promote domestic private credit to boost liquidity level to ensure long-term price stability and strengthen local industries production capacities.

This paper empirically examined the broad money demand function and its stability in two West African countries namely Cote d’Ivoire and Ghana covering the period of 1980 to 2015 using the Autoregressive Distributed Lag (ARDL) Bounds testing procedure. The empirical results confirm the stability of the money demand function and support the choice of M2 as a viable instrument for policy implementation in both countries cited above. The study also demonstrates that a long-run relationship exists between money aggregate (M2) and its determinants during the study period. In fact, the real income tends to be the most significant factor explaining the demand for broad money in both countries. In addition, the overall short run estimation of our model is statistically significant for Cote d’Ivoire and insignificant for Ghana at the conventional level. This means that money demand is stable for Cote d’Ivoire in short run and unstable for Ghana in the same period. It is recommended that monetary policy authorities should continue to implement policies that will reinforce macroeconomic stability and facilitate economic growth.

This paper examines the relationship between financial development, economic growth and energy consumption in Cote d’Ivoire over the period 1971-2011. To do so, the study first built a synthetic indicator of financial development through the principal component analysis technique (PCA) and used four energy sources such as electric power consumption, electricity production from renewable sources, electricity production from oil sources and electricity production from hydroelectric sources. Then, employing the autoregressive distributed lag (ARDL) bounds testing approach to cointegration, we find that there is a long run relationship between financial development, economic growth and energy consumption sources. Furthermore, the results of the vector error correction models (VECM) reveal unidirectional causality running from financial development to energy consumption sources, bidirectional causality between economic growth and energy consumption and unidirectional causality from financial development to economic growth in the long run. The mixed results are due to the use of different proxies for energy consumption. Accordingly, this paper recommends that policy makers should solicit the support of financial sector in order to solve energy problems and further the diversification of the energy consumption sources since financial development has a positive effect on energy consumption in long run. Moreover, government should develop public-private partnership (PPP) to stimulate economic growth, improve the access to energy and maintain a sustainable development in Cote d’Ivoire.

This study aims to model the long run determinants of domestic private investment in Côte d'Ivoire. Advanced econometric technique of Auto-Regressive Distributed Lag (ARDL) bounds testing approach is employed. Data from our study covers the period from 1970 to 2012. The results indicate that public investment, foreign direct investment, trade are the major determinants of short run and long run domestic private investment in Côte d'Ivoire while the real GDP growth rate and the interest rate are statistically insignificant. Thus, efforts should be geared to the development of necessary public investments in infrastructure such as supply constant electricity, good highways and elimination of the negative effects of external shocks engendered by the investment uncertainty and the deterioration of terms of trade.
