In this paper, we examine the ability of Fisher effect to describe the subjective behaviour of monetary policy responses for nations constrained by global factors. We developed and estimated a simple DSGE model for appraising the consequence of an integrated financial market predictor on national monetary policy response in Africa’s largest economies – Nigeria and South Africa. The paper integrated the theoretical intuition of the famous Fisher effect on the New Keynesian DSGE model with global predictors to describe national monetary policy response as it influence domestic financial variables and macroeconomic fundamentals. Simulations show that the existence of global factors threatens the abilities of national monetary policy to predict financial variables and macroeconomic fundamentals in their economies.

We examine the predictors of investment in the Chinese economy for the period 1973-2018. Our study adopts the Mark Nerlove (1962) partial adjustment hypothesis combined with instrumental econometric techniques based on the condition of the data used. Our results provide strong evidence that supports savings, export earnings, and final consumption expenditure as correlates of predictors of investment in China. Based on empirical results, we strongly recommend the integration of the unbaked population to a formal financial service to further stimulate more investment in the Chinese economy.

This paper forecasts the world population using the Autoregressive Integration Moving Average (ARIMA) for estimation and projection for short-range and long-term population sizes of the world, regions and sub-regions. The study provides evidence that growth and population explosion will continue in Sub-Saharan Africa, tending the need to aggressively promote pragmatic programmes that will balance population growth and sustainable economic growth in the region. The study argued that early projections took for granted the positive and negative implications of population growth on the social structure and offset the natural process, which might have implication(s) on survival rate. Given the obvious imbalance in population growth across continents and regions of the world, a more purposeful inter-regional and economic co-operation that supports and enhances population balancing and economic expansion among nations is highly recommended. In this regard, the United Nations should compel member states to vigorously and effectively implement domestic and international support programmes with this objective in view.

The study investigates the effect of New Keynesian liquidity trap on fiscal stance in the United States, United Kingdom and Japan economies. We developed our DSGE model in the context of an optimal and persistent interactive fiscal policy, which allows us to track the transmission channel through which shocks are distributed among real economic variables. The evidence suggests that zero lower bound mitigates the ability of monetary policy to absorb the effect of exogenous shock on the macroeconomic variables while expansionary fiscal policy was able to absorb the shock persistence transmitted from the nominal interest rate.
