There is a pool of techniques and methods in addressing dynamics behaviors in higher frequency data, prominent among them is the ARCH/GARCH techniques. In this paper, the various types and assumptions of the ARCH/GARCH models were tried in examining the dynamism of exchange rate and international crude oil prices in Nigeria. And it was observed that the Nigerian foreign exchange rates behaviors did not conform with the assumptions of the ARCH/GARCH models, hence this paper adopted Lag Variables Autoregressive (LVAR) techniques originally developed by Agung and Heij multiplier to examine the dynamic response of the Nigerian foreign exchange rates to crude oil prices. The Heij coefficient was used to calculate the dynamic multipliers while the Engel & Granger two-step technique was used for cointegration analysis.  The results revealed an insignificant dynamic long-term response of the exchange rate to crude oil prices within the periods under review. The coefficient of dynamism was insignificantly in most cases of the sub-periods. The paper equally revealed that the significance of the dynamic multipliers depends greatly on external information about both market indicators which are two-way interactions. Thus, the paper recommends periodic intervention in the foreign exchange market by the monetary authorities to stabilize the market against any shocks in the international crude oil market, since crude oil is the main source of foreign exchange in Nigeria.

This paper is driven by the vast influence oil money have on the current account balance of major oil producing countries in Africa and the role policy measures could play to soften these effects. Dwelling on the nonlinear techniques, two types of Threshold Regression were used to estimate data on 8 African countries from 1995-2019. The results show evidence of nonlinear impacts of oil revenue on the current account balances of the 8 countries. The nature of the impact relies significantly on the levels of the threshold variable. Precisely, the estimated threshold benchmark for financial development was 33.34; below this threshold the sensitivity of current account balance to crude-oil shocks is higher and the probability of policy measures to mitigate the effects is low and, beyond the threshold the sensitivity of current account balance to crude-oil shocks is low and the probability of policy measure to mitigate the effects is higher. The finding suggested among others that crude-oil shocks is not the primary problem of the current account imbalance of oil-exporting countries rather the nature of the domestic economic policy environment.

The improvement in the standard of living of citizenry is beyond lack of money but the poverty to access financial instruments and means to financial platforms. Such that lack of access to financial instruments and services is a major veritable channel for poverty amplification in the society. This paper examines the relationship between Mobile Money Operations (MMOs) and Financial Inclusion in the Niger Delta region of Nigeria. The paper also analysis the trends of the instruments of financial inclusion and MMOs in Nigeria from 2012 to 2019. The primary and secondary were data sourced and analyzed with the Net Balance Methods, Instruments of inferential and descriptive statistics. The survey results show a visual cycle of higher number of respondents with secondary school qualifications and less which have led to low income and an ineffective participation to mobile money and financial inclusions in the rural areas. We equally observed that poor internet and mobile networks, epileptic power supply, unclear economic policies among others are major setback for the insignificant relationship between MMOs and financial inclusion in the Niger Delta region. This implies that the growth of mobile banking and financial inclusions to facilitate financial system soundness and enhances economic growth and development required more motivations from institutions other than the financial institutions; as a ways of encouraging increased Nigerians participation. Base on the result the paper can assumes that the financial system has provided the needed instrument for citizen participation but the social and economic conditions of the country is the bottleneck for financial inclusions.
