An excessive increase in public debt characterizes the contemporary development of the global economic and financial system. The paper aims to examine the short- and long-run impact of state debt on economic growth in Nigeria. The model was estimated using an autoregressive distributed lag (ARDL) bounds testing method to co-integration for the long-run investigation. At the same time, the contemporaneous dynamics were explored using an unrestricted error correction model. The data were collected from the Central Bank of Nigeria’s statistical bulletins and annual reports, and it spanned the years from 1990 to 2020. The study uncovers evidence of a long-term link between the study variables. In addition, the study finds that all the explanatory is statistically significant. Specifically, economic growth is significant and negatively responsive to changes in external debt by 0.19% and debt servicing by 0.07%, contrary to its positive response to changes in domestic debt and exchange rate by 0.27% and 0.18%, respectively. The paper, therefore, recommends that government may consider more domestic borrowings to foreign borrowings that should only be resorted to when it is indispensable. Moreover, the government should also strive to balance loan servicing and the economic sustainability.

<p>The paper focuses on the impact of macroeconomic determinants on industrial productivity in Nigeria for the period, 1981-2013. It was discovered that while the Nigerian government had embarked on a number of industrial development strategies with the sole purpose of boasting industrial productivity in Nigeria, they seem to have yielded little or no result. The macroeconomic variables in the study include industrial production index, exchange rate, consumer price index, interest rate, broad money supply, foreign direct investment, credit to manufacturing sector and gross domestic product. The study employed OLS technique and found that exchange rate exert significant positive impact on industrial productivity in Nigeria.  Also, the impact of interest rate, FDI and real GDP on industrial production index is positive. On the other hand, consumer price index, broad money supply and credit to manufacturing sector exert negative impact on industrial development in Nigeria. The paper recommended that a workable M2 that can enhance credit to manufacturing sector and at the same time control interest rate to boast investment should be determined.</p>

The paper aims to develop scientific and methodological approach to assessing the interaction of nonperforming loans of Ukrainian banking institutions, the profitability of the banking sector and its financial stability, which will allow a more detailed assessment of the directions and degree of mutual influence of these elements. To substantiate this interaction economically and mathematically, structural equation modeling was chosen. Particularly, Statistica was chosen as a software tool to assess the adequacy of the resulting model and determine the level of statistical significance of its parameters. Six key indicators were selected as a research information base, two for each subject of research: indicators of nonperforming loans in the banking sector (the volume of nonperforming loans and the ratio of problem loans excluding capital reserves), profitability indicators of the Ukrainian banking sector (assets profit and rate of return on capital), and indicators of financial stability of the Ukrainian banking sector (regulatory capital-to-risk-weighted assets ratio and liquid assets-to-total assets ratio). For calculations, statistic data of selected indicators for 2005–2019 were used. As a result of calculations, mathematical data were obtained that accurately described the interaction of nonperforming loans of Ukrainian banking institutions, the profitability of the banking sector and its financial stability. The adequacy of the model was verified based on the following criteria: main summary statistics (ICSF criterion, ICS criterion, discrepancy function, maximum residual cosine), noncentrality fit indices (noncentrality parameter, population noncentrality parameter, Steiger-Lind RMSEA index, McDonald noncentrality index, adjusted population Gamma index), other single sample indices (Akaike information criterion, Schwarz criterion), and a normal probability plot.

The paper explores theoretical and practical aspects of forecasting the government debt in Ukraine. A visual analysis of changes in the amount of government debt was conducted, which has made it possible to conclude about the deepening of the debt crisis in the country. The autoregressive integrated moving average (ARIMA) is considered as the basic forecasting model; besides, the model work and its diagnostics are estimated. The EViews software package illustrates the procedure for forecasting the Ukrainian government debt for the ARIMA model: the series for stationarity was tested, the time series of monthly government debt was converted into stationary by making a number of transformations and determining model parameters; as a result, the most optimal specification for the ARIMA model was chosen.Based on the simulated time series, it is concluded that ARIMA tools can be used to predict the government debt values.

Attracting foreign investment is a viable means of ensuring the economic growth of any country. The relevance of the study is substantiated by the creation of a favorable investment climate in the country, which will allow the establishment of guarantees of protection of foreign investments and stability of the legal basis for entrepreneurship performance. The article aims to analyze and forecast the inflow of foreign direct investment (FDI) into Ukraine. In order to achieve the stated purpose, the econometric model was developed, which demonstrates the correlation between macroeconomic indicators, their characteristics and the amount of FDI. A set of general scientific and special research methods were used, in particular: induction and deduction, grouping, summarization, comparison, complex and systemic approaches. The article reveals the essence of foreign investment for the Ukrainian economy and defines the characteristics of FDI. The impact of FDI on the economy of Ukraine is analyzed in detail and the conditions for their attraction are substantiated. Using statistical methods, the structure and dynamics of FDI by types of economic activity and investor countries are investigated. The conducted research has shown that through the attraction of foreign direct investment economic growth, the well-being of the population, the reduction of foreign indebtedness and efficient state capital investments are ensured. Taking all this into account the necessary preconditions for the attraction of foreign direct investments into the Ukrainian economy were substantiated.
