Since the 1990s, the economic growth of the West African region has been remarkable, with average GDP growth of 5 per cent annually. In view of that, this article investigates the Total Factor Productivity (TFP) performance for the Economic Community of West African States (ECOWAS) region, which takes into account the recent development on political stability and trade openness. There were also periods when TFP fell sharply, the most significant happened in the late 1990s and 2000s where TFP dropped significantly which might be attributed to the spillover effect of the Asian and global financial crises. Our results showed that TFP was performing well for the region as well as for each member countries for the period of the study. We acknowledged that the estimated TFP in our model captures other factors such as human capital, health and other institutional factors that could affect economic growth. We also estimated the Technical Efficiency (TE) for the ECOWAS region using the Stochastic Frontier Modelling and the result indicates that the TE performance is well below the optimal level of production.

Southeast Asia has experienced an economic growth since the 1980s. This growth triggered by reforms to increasing global and regional integration has been remarkable. This article aims to examine whether regional integration promotes economic growth in Southeast Asia. It further investigates whether the economic and social factors affect economic growth. The panel data were collected over 43 years (1970–2013) in Southeast Asia. We employ a cross-country growth model using a generalized method of moments in the dynamic panel framework to empirically examine the impact of regional integration on economic growth. Our results found that regional integration had a significant effect on economic growth. More specifically, our empirical results suggest that, in order to enhance regional integration and economic growth in the region, public institutions should work towards eliminating corruption and stabilizing macroeconomics and political stability while promoting international trade among member countries. This article sheds light on the key determinants of economic growth and policy formulations to achieve higher economic growth in Southeast Asia.

Interest rates are critical to any economy. Usually the central bank of a country supervises and tries to control the interest rates but there is always an element of uncontrollable effects: local or international. A central bank adopts a monetary strategy to affect various macroeconomic parameters such as inflation, exchange rate (ER), economic growth and many others. A country may decide to adopt Ultra-low Interest Rate Policy (ULIRP) or Negative Interest Rate Policy (NIRP) or a policy with moderate/high rate of interest. In today’s global business scenario, economies are connected and influence one another. The US and UK economies have seen a very low and negative interest rates historically, at least in recent past. Indian and Sri Lankan economies are integrated with the US and UK economies and thus are affected by their prevailing interest rates. The effect of low and zero interest rate policy of a country (USA and UK) on interest rates and economy of co-integrated economies (India and Sri Lanka) have been studied in this research. The objective of this study is to understand the implications of ULIRPs and NIRPs in the context of Indian and Sri Lankan economies. Two significant conclusions of the research are that Indian and Sri Lankan economies are affected by the US and UK policies and that they are affected at a lag of eight years.
