The study examines the effect of ATM on the performance of deposit money banks in Nigeria for the period of 7 years from 2012 to 2018. The study adopted ex-post research design. The population of the study is all the deposit money banks in Nigeria. The study collected data from the Central Bank of Nigeria statistical bulletin. The study adopted pre-test analysis of correlation and unit root test using Augmented Dickey- Fuller (ADF) test. After analysizing the unit root test, regression was used. The study found that there was a positive and insignificant effect of ATM on performance of deposit money banks in Nigeria. Other findings were that volume of transaction of ATM has positive and insignificant effect on the return on asset of deposit money banks in Nigeria while value of transaction of ATM also has positive and insignificant effect on return on asset of deposit money banks in Nigeria. The study recommended that ATM machines should be re-strategies by deposit money banks in Nigeria and they should careful increase the volume of transaction by ensuring that network is properly maintain. They should use ATM network that is very good to satisfy customers during weekends. They should provide more ATM and encourage customers to use ATM and try to reduce the problem of cash jam and lack of cash dispense.

Nonlinear Unit Root Tests

This paper aims to explore the convergence of per capita carbon and ecological footprints in G7 countries during 1961–2016. For this purpose, we propose a new unit root test in the panel setting–the panel Fourier threshold unit root test. This test takes into consideration both multiple smooth structural changes and nonlinearity. According to the literature, the power of the nonlinear unit root tests is reduced in the case of ignoring structural breaks. Therefore, we expect to get more reliable empirical findings by utilizing this methodology. The empirical results of this paper show that these series have nonlinear behaviors for the period 1961–2016. Furthermore, they demonstrate that the absolute convergence hypothesis is valid in G7 countries for both regimes. Thus, governments can conduct common environmental policies, including international climate summits and agreements, instead of national-based policies to mitigate environmental deterioration in their countries.

Long Run

This study examined short run and long run relationship between endogenous and exogenous variables. Specifically, it studied the relationship between real export, real import, labor force participation and real effective exchange rate (REER) and real GDP in Malaysia from 1988 to 2017. These variables were tested in various tests, namely, unit root test, granger causality test, vector autoregressive (VAR), Johansen Juselius test and Error Correction Term (ECT). The result revealed that all variables were non-stationary at the level form and stationary at first difference in ADF unit root test. The findings also exhibited the existence of bilateral relationships between real export and real GDP, real import and real GDP, as well as labor and real GDP. Nonetheless, there were no relationship found between REER and real GDP. On the other hand, in VAR, the lag optimum was lag 10 because it indicated the smallest value of AIC. Moreover, for Johansen Juselius cointegration test, it showed two cointegrated vector at both, 5% and 1%, level in trace test. In addition, Max-Eigen value test indicated two cointegrated vector at 0.05 and one cointegrated vector at 0.01. As for the Wald test, there were long run cointegration relationship between real GDP and its determinants, namely real export, real import, labor and REER. Apparently, Malaysia, as a small open economy, has relied heavily on foreign trade. Consequently, our domestic economic performance is susceptible to the changes in international markets and exchange rate. Therefore, suitable international policy implementation is vital to ensure Malaysian economy will be able to adjust to current global changes.
