The Impact

In China, the thermal power is the main structure of power source. We consider that analysis thermal power’s date generation process is very important to precise planning of thermal power and whole electricity market. For testing the impact of inspection and external factors on thermal power, we study date generation process of thermal power by structural change model that carry unit root test and trend stationary test. This conclusion indicates that thermal power’s date generation process is the unit root process of structure change and isn’t trending stationary process.

The Relationship

The main objective of this paper is to examine the relationship between tax revenue and economic growth in Nepal. The 43 years' annual time series data from 1974/75 to 2016/17 of GDP, tax revenue and nontax revenue have been used to test the causal relationship of the variables. A unit root test, Engle-Granger’s co-integration and Error Correction Model have been applied for the data analysis. The variables have been found stationary after first differencing I(1) when Augmented Dickey-Fuller unit root test is employed. From Engel-Granger test, it has been found that the variables are co-integrated. The short-term coefficients are not significant, however error correction term (ECT) is significant and contains a negative sign in the error correction model (ECM). It validates the ECM model. The ECT has shown that the annual speed of adjustment from disequilibrium to equilibrium is 34.3 percent. So far as the relationship is concerned, there is a long run relationship between tax revenue and economic growth in Nepal controlling the non-tax revenue. The impact of tax revenue on economic growth could be a good impetus for the policy maker and planner to increase the collection of revenue for the country.

The Impact

The primary aim of this study is to analyze the impact of financial services and real sector confidence indexes on some macroeconomic and financial indicators such as industrial production, inflation, stock market index, foreign exchange rates and interest rates in Turkey for the period from May 2012 to May 2019. In this study, the unit root properties of these series are tested by using the Narayan and Popp (2010) unit root test with two structural breaks and the Enders and Lee (2012) Fourier ADF unit root test with multiple structural breaks. We investigate the causal link between confidence indicators and macro-financial variables using the Fourier Toda Yamamoto causality test proposed by Nazlioglu et al. (2016). The results suggest a strong link between financial services and real sector confidence indexes on macro-financial indicators such as stock market index and inflation, supporting the evidence of the short-run impact of confidence indexes on these variables.

The Impact

This paper examines the impact of public capital expenditure on inflation rate in Nigeria. The data for the study were sourced from various issues of the Central Bank of Nigeria’s statistical bulletin. The data was subjected to unit root test using Augmented Dickey fuller (ADF) approach to ascertain the time series properties. Descriptive statistics was used to assess the socioeconomic characteristics of the variables. Due to the mixed order of integration witnessed in the unit root, ARDL- Autoregressive Distributed Lag approach was used for cointegration and regression analysis. The result found that Public capital expenditure is negatively and statistically significant (tcal = -2.903) in influencing Inflation Rate in Nigeria. This outcome is highly directional in the sense that prudent and productive spending will always subdue inflation in any economy; therefore, this study recommend that government should increase its investment in production sectors and encourage skilful and willing citizens to participate, since this would reduce the expenses being incurred on business as a result low currency value and raise the profitability of firms.

The Current Account

In this study, we examine the linkages between External debt, Exchange rate, Current account deficit, and GDP at Factor cost for India over the period of 1975-76 to 2018- 19 using the Unit root test and Autoregressive Distributed Lag (ARDL). The results of the unit root test reveal that GDP growth rate and External debt are integrated at the level I(0); while the Current Account deficit and Exchange rate are integrated at first order I(1). The results of the ARDL technique reveal that the current account deficit has a positive and significant impact on Real GDP. It clearly reflects the role of imports in accelerating the growth of a developing economy like India. There is also evidence that the external debt has a positive and significant impact on the Current account deficit while the Exchange rate does not have an impact on the Current account deficit. The authors opine that the external debt assists in a gradual reduction in the current account deficit and contributes to economic growth by narrowing down the saving-investment gap. As the demand for Indian exports is inelastic in the global market, the country has not benefitted from the depreciation of its currency. The authors stressed the need for focusing on further diversification of its export markets, creating a conducive environment for attracting longer-term FDIs, liberalization, promoting commercial services exports, and achieving exchange rate stability in the context of the USA-China trade war and stagnation in the world output growth. Huge untapped potential for IT-enabled services should be exploited to promote service trade. The authors point out the current account deficit in the range of 2-3 percent of GDP can be manageable.

The Impact

In this paper we investigate the impact of persistent (nonstationary or near nonstationary) cycles on the asymptotic and finite-sample properties of standard unit root tests. Results are presented for the augmented Dickey–Fuller (ADF) normalized bias and t-ratio-based tests (Dickey and Fuller, 1979, Journal of the American Statistical Association 745, 427–431; Said and Dickey, 1984; Biometrika 71, 599–607). the variance ratio unit root test of Breitung (2002, Journal of Econometrics 108, 343–363), and the M class of unit-root tests introduced by Stock (1999, in Engle and White (eds.), A Festschrift in Honour of Clive W.J. Granger) and Perron and Ng (1996, Review of Economic Studies 63, 435–463). We show that although the ADF statistics remain asymptotically pivotal (provided the test regression is properly augmented) in the presence of persistent cycles, this is not the case for the other statistics considered and show numerically that the size properties of the tests based on these statistics are too unreliable to be used in practice. We also show that the t-ratios associated with lags of the dependent variable of order greater than two in the ADF regression are asymptotically normally distributed. This is an important result as it implies that extant sequential methods (see Hall, 1994, Journal of Business & Economic Statistics 17, 461–470; Ng and Perron, 1995, Journal of the American Statistical Association 90, 268–281) used to determine the order of augmentation in the ADF regression remain valid in the presence of persistent cycles.

The Impact

The study comparatively examined the impact of oil rent on healthcare in Nigeria and Cameroon from 1995 to 2015. The objectives of the study are to; study the trend of oil rents and healthcare in Nigeria and Cameroon; examine the relationship between oil rent and healthcare of Nigerians and Cameroonians and determine the impact of mineral rent on the healthcare of Nigeria and Cameroon. To achieve these objectives panel data were collected on health, oil rent and mineral rent and analyzed using the econometric techniques of panel unit root test and panel cointegration test as well as graphical method. The panel unit root and cointegration test showed that all the series are indeed stationary and have long run equilibrium relationship. Comparatively, the graph showed that the rents from oil in Nigeria are lower than that of Cameroon. Also, Cameroon performs better in rents from minerals than Nigeria. Thus, Cameroon capital expenditure on health has steadily increased since 1995 up to 2015 while Nigeria seems not to take healthcare expenditure serious hence the dismal performance in the infant mortality rates. Based on the findings, it is recommended that revenue from oil should be towards inclusive growth, thereby impacting significantly on the healthcare and welfare of the citizens. Thus, there should be investment in primary as well as maternal health in the rural areas for the disadvantaged in society.

<p><em>Despite the Central Bank of Nigeria’s (CBN) initiatives to encourage banks to extend their services and facilities to rural areas, a high percentage of the rural dwellers still remain unbanked and as such, the initiatives appear not to promote financial inclusion services among the poor in Nigeria. As a result, small entrepreneurs often lack enabling financial environment to grow. The study undertakes an empirical analysis of the impact of microfinance in promoting financial inclusion in Nigeria between 1990 and 2014 using OLS regression method. Unit root test was conducted on the variables to examine their level of stationary to avoid spurious regression results. The findings showed that minimum deposit amount have a positive and significant relationship with saving. It was observed that access to microfinance minimum deposit amount has significant effect on savings account opened by rural dwellers. Microfinance interest rate was however found to have a negative and insignificant relationship with the rural dwellers loans and advances.</em><em> </em><em>Recommendations were made among which are that Government should facilitate microfinance branches close to the rural area, products and services accessible to a large segment of the potentially productive Nigeria population, who are currently not being served by the formal financial sector.</em></p>

The Impact

The goal of this study is to determine the impact of non-performing loans (NPLs) on the financial performance of all Bangladeshi listed banks. To accomplish so, the study analyzed data from the previous twenty-three years, from 1997 to 2019 in order to find out the effects of non-performing loan ratio (NPLR), capital adequacy ratio (CAR), inflation (INF) and provision maintenance ratio (PMR) on the return on asset (ROA). Researchers have attempted to investigate the primary cause of NPLs and their implications while taking into account a number of bank-specific characteristics as well as macroeconomic factor. The annual reports from Bangladesh Bank are considered for collecting data that has been examined through OLS and VAT models, along with Test of Heteroscedasticity, Test of Normal Distribution and also Unit Root Test by using STATA 11 (statistical software). By analyzing the OLS regression, it has found that all independent variables i.e. NPLR, CAR, INF and PMR are statistically noteworthy to explain the dependent variable i.e. ROA.
