Today, the role of government spending which is considered as the main instrument in the promotion of economic development is seen in the public investment budget (PIB). This study analyzes the role of the public investment spending in the economic growth of Cameroon. Specifically, it brings out the effect of Public and Private Investment on GDP growth in Cameroon. The role of the PIB as an instigator of economic growth should be clarified in order to justify government investment expenditure. Many studies have analysed the relationship between government spending and economic growth but the analysis of the composition of government spending and induced economic growth is an aspect of economic analysis which deserves more interest. This study analysis the effect of government investment spending on economic growth in Cameroon going from the components of the GDP5 and using VAR (Vector Auto Regressive) model. Our results show the intervals in which the various components of government spending have an effect on economic growth in Cameroon. We find that the lagged GDP and government investments have a positive effect on growth whereas private investments affect it negatively.

The aim of this paper is to analyze the impact of human capital, notably education, on environmental quality in Cameroon. Used is made of ARDL bound testing techniques to analyze annual data spanning the period 1971-2019. The data was obtained from the World Development Indicators published by the World Bank website. The results show a positive impact of human capital development on environmental quality. Also, evidence was found to support the existence of the environmental Kuznets curve in the context of Cameroon. These results indicate that the government of Cameroon can improve on its environmental quality by developing the human capital of its citizens. This can be done by enhancing environmental education in the country.

The aim of this study is to analyse the relationship between financial liberalization, financial development and economic growth in Cameroon. Use is made of a tri- variate VAR model on Cameroon data for the period 1973- 2017. The results obtained show that financial liberalisation and financial development positively affect economic growth. Though financial development does not individually cause economic growth, when considered with financial liberalisation, they jointly cause economic growth.Financial liberalisation and economic growth are individually and jointly found to granger cause financial development. Financial development causes financial liberalisation while economic growth causes financial liberalisation only when jointly considered with financial development. The impulse response functions reveal that economic growth positively responds to both financial development and financial liberalisation though the effect of financial development soon fates out to become negative.Financial development is found to positively react to innovations in financial liberalisation and negatively to economic growth.As concerns financial liberalisation, it negatively responds to financial development and positively to economic growth. Also,variance decomposition reveals that variations in economic growth are mostly explained by its past values, followed by financial liberalisation and finally financial development. Financial development on its part is also mostly explained by its past values followed by financial liberalisation and finally economic growth. Based on all these, the policy recommendation we make is that the on-going financial liberalisation process in the country should be enhanced in view of permitting the financial sector to efficiently play its role in the growth process of the country.

This study examines the relationship between internal absorption, financial and business cycles in selected African countries. Using Markov's regime change model on data for the period 1960-2018. The data was obtained from the online version of the World Bank's World Development Indicators. The results show that the Keynesian or monetary effects on each phase of the business cycle is different in the various countries. During the phase of economic expansion, the rate of evolution of consumption and gross fixed capital formation accelerate the expansion trend. During the phase of recession, these variables play a stabiliser role by moderating the fall in real GDP. Liquidity ratio and nominal exchange rate affect the behaviour of real GDP in a mixed manner in both the phase of economic expansion and economic recession. These results show that economic policies should focus on household consumption and gross fixed capital formation to regulate the dynamics of the economy. Contribution/ Originality:This study uses a new estimation methodology-Markov's regime change modelto ascertain the relationship between financial, absorption and business cycles in a developing country Cameroon.Furthermore, the study contributes to the literature on business cycles by distinguishing deterministic cycles from stochastic cycles using the market hypothesis equilibrium.
