Nexus of bank personnel and cost-income ratio (CIR) in Nigeria

The purpose of this paper is to provide an analytical analysis of cointegration between Europe and the other significant trading partners, namely US, China, Japan and Australia, for the period from January 1, 2010 to December 30, 2016. This captures the impact of the sovereign European debt crisis and the Greek crisis. A range of parametric techniques were adopted including Johansen cointegration analysis, Vector Error Correction Model and Granger causality. The results of the crisis Granger causality test during the European sovereign crisis implies the highest influence to be that of the US and Japanese stock market over the other four markets. Overall, found that the Asia-Pacific region plus the US stay closely related to each other, while European countries influence all the studied markets except each other. For the post-crisis sub-period, the Granger causality is slightly different. It is observable that the UK and Germany are influencing all the markets. This is probably due to the recent Brexit referendum outcome and potential consequences not only for the EU, but also for the rest of the world too. Overall, the Granger outcome shows the dependence between Europe and other global markets, but there is no European interdependence during the sovereign debt crisis period. It may be concluded that there is a separation of Asian markets from the European markets and even though cointegration exists, the relationship is rather weak.

Foreign direct investment (FDI) inflows to Vietnam have increased significantly in recent years. Theoretically, capital inflows will put pressure on the overvaluation of local currencies in countries, despite different exchange rate mechanisms. So, the problem facing the Vietnamese government is the need to examine the relationship between the exchange rate and FDI in order to develop effective policies. This study examined the relationship between the exchange rate and FDI in Vietnam in the period of 2005–2019 using the VAR (vector autoregression) model based on quarterly frequency data. The new points of this study are: (i) using the real effective exchange rate (REER) of the Vietnamese currency with 143 major trading partners of Vietnam; and (ii) adding two control variables into the VAR model to examine the relationship between the exchange rate and FDI in Vietnam – a case study for developing countries. The findings show that, firstly, there is a positive causal relationship between FDI and Vietnam’s real effective exchange rate. Secondly, trade openness has a positive impact on FDI and REER in Vietnam. Thirdly, economic growth has an impact on REER, but no statistically significant impact on FDI was found. The findings can provide useful information to help policymakers plan and make decisions on future policies and support further research studies.

The integration of the Slovak Republic into the European Union and the globalization process create conditions that significantly reduce barriers to entry into particular markets, but, on the other hand, enhance the intensity of competition. The relevance of the study lies in the extent of the European Union’s support for the effectiveness of innovation activities in Slovakia. This paper investigates the influence of endogenous and exogenous factors on the competitiveness of Slovak enterprises over the period 2006–2018. The study is aimed at determining the causal relationship of factors that determine the competitiveness of enterprises. To investigate the relationship between the endogenous and exogenous factors, the Granger causality method is used. Mathematical models are used to identify the relationship between innovation expenditures on the one hand and different types of innovation activity with market expansion on the other. The results of the study provide a statistically significant relationship between the performance measured by the percentage of revenues of enterprises that have introduced innovations with a two-year lag and the concentration measured by the total R&D expenditure of an enterprise. The results of this study should also be used to ensure that, in the case of the Slovak SME sector, R&D expenditure is a significant driver of innovation in enterprises, as innovation in enterprises is expected to improve the quality of products and services, increase profits and expansion in domestic and foreign markets.
