In his "The World’s smallest macroeconomic model” (Krugman (1999)), Paul Krugman argued that under the assumption of price rigidity, a shortage of money supply leads to underemployment or recession, so increasing money supply can eliminate underemployment and restore full employment. But, how do we increase the money supply? I will show that we need a government deficit to increase the money supply in order to restore full employment from recession. Also, I will show that in a growing economy, if people hold money, a government deficit is necessary to maintain full employment under constant price or inflation. A government deficit is not only effective in pulling the economy out of recession, it is even necessary for continued growth without inviting either recession or inflation. The government deficit in this paper represents the difference between government expenditures and government revenues. When the difference is positive, we say that the government has a deficit. This paper seeks to explore theoretically and normatively the role of government deficits in achieving and maintaining full employment in a growing economy without causing inflation, using a very simple model by Krugman.

We employ the joint production decomposition model to conduct a full decomposition of CO2 emission among 36 industrial sectors in China from 1998 to 2011, under the framework of growth accounting. The results show that: (1) the average CO2 emission increases at an annual rate of 3.01%, and production technology progression is the main driving force, while the transformation toward clean production effectively curb the rapid growth of CO2 emissions; (2) the effect of technology changes on CO2 emission is larger during the "10th Five-Year Plan" compared with the "11th Five-Year Plan", which makes the annual growth rate of CO2 emission during the "11th Five-Year Plan" 1% lower than its counterpart; This study has important theoretical and practical significance for understanding the driving factors of CO2 emission and the corresponding emission reduction measures.

The paper examines how the growth of entrepreneurship affects the generation of employment opportunities in Nasarawa State. Even though entrepreneurship is crucial for generating employment, there are still obstacles in the way of its growth. These include limited support from governmental and non-governmental organizations, difficulty obtaining financing and microcredit, proper training and enlightenment etc. The objective of this paper is to investigate how the growth of entrepreneurship affects the creation of jobs in Lafia, Nasarawa State. The study used a descriptive research design, and the means used for gathering data was a questionnaire given to new entrepreneurs in Lafia, Nasarawa State. A sample size of 375 was determined from a population of 1604 using a Smith (1984) sampling formula; this sample represented the number of questionnaires that were delivered. This findings of the research demonstrated that the creation of jobs in Nasarawa State is significantly impacted by the growth of entrepreneurship. This implies that through entrepreneurship development, self-reliance and employment opportunities have been created in Lafia, Nasarawa State. Through this, youths have been able to develop a way to create value in the society. More so, this study revealed that access to credit (micro credit) has a significant effect on employment creation in the State. Having acquired knowledge on how to manage finance they make sound financial decisions. Lastly, the study showed that the number of new businesses established has a significant effect on employment creation in Nasarawa State. This result implies that youths who apply their entrepreneurship skills and creativity in one nature of business or the other have been able to earn a living out of it in Nasarawa State. This paper thus suggests that the Nasarawa State government should genuinely recognize the relevance of entrepreneurship development and provide an enabling environment. Both the government and institutions should ensure that youths get adequate financial credit (micro-credit).

In the dynamic landscape of exponential growth in the games industry, crowdfunding has emerged as an important funding method for indie games. Previous research has provided inconsistent results on the factors behind its success. This study closes this gap by examining which factors influence success and how success factors vary with different definitions of success and funding goals. The results show that caution is needed when interpreting the results as they depend on model specifications even within the same dataset. Furthermore, the study proposes a framework, supported by an empirical analysis of 1,967 campaigns, to increase the probability of crowdfunding success.

This study examines the factors influencing inflation stability in Nigeria from 2011Q1 to 2023Q1. We employ an ARDL model to assess the impact of monetary policy rate, money supply, crude oil price, GDP growth, and government budget deficit on inflation. Our findings reveal that broad money and fiscal deficit exert a positive and statistically significant influence on inflation in both the short and long run. Interestingly, monetary policy rate only affects inflation in the short term. These results suggest that Nigerian policymakers should prioritize managing broad money and fiscal deficits to achieve long-term inflation stability.

We analyze the annual microdata of China's 100 commercial banks from 2007 to 2018 using the mediating effect analysis method, analyze the negative impact of economic policy uncertainty on the credit scale of commercial banks, and then verify the intermediary effects of the operational risks and short-term capital liquidity of commercial banks in the impact of economic policy uncertainty on the scale of commercial bank credit, separately. Moreover, we find that non-state-owned commercial banks, large-scale commercial banks, low-leverage commercial banks, and commercial banks with low profitability are more susceptible to economic policy uncertainty affecting commercial bank credit growth through short-term capital liquidity, and vice versa.

The paper is motivated by the growth of the electronic payments system and its relevance in enhancing the banking industry's earnings. Consequently, the paper examines the causal relationship between the electronic payments system and the banking industry's returns in Nigeria. The paper offers some important contributions to the literature involving the use of an approach that allows for data-driven identification of the change points in the electronic payments system and the banking industry's returns nexus. The paper discovered three important findings. First, the causal relationship between the electronic payments system and the banking industry's returns in Nigeria changes with time changes. Second, there is evidence of causality between the electronic payments system and returns on assets and equity, however, the causality was more evident under the recursive window. Third, the causal relationship was more evident in some specific periods such as 2020Q4, all quarters of 2015 to 2016, and 2020 to the end of 2023. The paper recommends that policymakers should revisit and reinvigorate the specific cashless policies instituted in 2012-2016 that aided higher returns to the banking industry. Similarly, the Central Bank of Nigeria and other banking industry players should intensify efforts to encourage the use of electronic payments due to their usefulness and ability to enhance the banking industry's earnings.

The study investigates the impact of COVID-19 on African exchange rates, employing a panel dataset over the period 2016-2022 from 13 African economies and employing pooled OLS estimator. The findings reveal a noteworthy positive correlation between COVID-19 levels and exchange rates within the region. However, this association necessitates deeper exploration due to its multifaceted implications, including economic disruptions, government interventions, global market interconnections, regional stability perceptions, and investor behavior. Economic indicators, such as GDP, inflation rate, real interest rate, and unemployment rate, significantly influence exchange rates. While GDP positively impacts exchange rates through economic growth, investor confidence, and trade strength, controlled inflation fosters investor confidence and export competitiveness, positively affecting exchange rates. Moreover, a pronounced positive impact of the real interest rate indicates economic stability, attracting investment and contributing to currency appreciation. Conversely, high unemployment negatively affects exchange rates, signaling economic weaknesses and eroding investor confidence. These findings emphasize nuanced policy responses for managing health crisis-induced economic disruptions and suggest future research directions focusing on specific country-level analyses and multifaceted factors influencing currency valuations within African economies.

This paper investigates the impact of monetary policy on the performance of deposit money banks in Nigeria, using monthly data series spanning the period 2008 to 2023. Total private sector credit of deposit money banks was used to proxy the performance of deposit money banks while money supply, monetary policy rate, cash reserve ratio, and maximum interest rate were used as proxies for monetary policy. The Ex-post Facto research design was adopted in this study. Data on total private sector credit of deposit money banks, money supply, monetary policy rate, cash reserve ratio, and maximum interest rate were obtained from the Central Bank of Nigeria (CBN) Statistical bulletin. The hypotheses of this paper were tested using the Autoregressive Distributed Lag statistics. The findings disclosed that total private sector credit of deposit money banks has a significant relationship with money supply and maximum interest rate while cash reserve ratio and monetary policy rate has an insignificant relationship with total private sector credit of deposit money banks. The researchers recommended among other things that the monetary authorities should consider policies that enhance liquidity within the banking system. This can be achieved through open market operations, reducing the reserve requirements, or other mechanisms that increase the availability of funds in the economy as the money supply was found to be statistically significant. Also, it is crucial for monetary authorities to monitor and adjust the maximum interest rates to ensure they remain conducive to deposit growth. High lending rates may discourage borrowing and subsequently reduce deposits, while more favorable rates could encourage economic activity and deposit inflows.
