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.

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).

I examine the problem of budget deficit in a growing economy in which consumers hold money as a part of their savings in the case where consumers live forever. For simplicity and tractability I use a discrete time dynamic model and Lagrange multiplier method. In the appendix I briefly explain the solution using a discrete time version of the Hamiltonian method. I will show the following results. 1) Budget deficit is necessary for full employment under constant prices. 2) Inflation is induced if the actual budget deficit is greater than the value at which full employment is achieved under constant prices. 3) If the actual budget deficit is smaller than the value which is necessary and sufficient for full employment under constant prices, a recession occurs. Therefore, balanced budget cannot achieve full employment under constant prices. I do not assume that budget deficit must later be made up by budget surplus.

In an effort to provide policy recommendations for Nigeria's transition to full-fledged inflation targeting, this study examines Ghana's monetary policy frameworks (monetary aggregates targeting and inflation targeting) using ARDL bounds test for cointegration and Error Correction Mechanism (ECM) on annual time series data spanning 1965 to 2022 obtained from the Bank of Ghana database and the World Bank database on World Development Indicators. The results demonstrate that monetary aggregates targeting has not been successful in both the short-run and long-run periods in moderating and stabilizing inflation; however, inflation moderated under inflation targeting in both the short run and the long term. This indicates that inflation targeting proves to be a superior monetary policy framework for inflation control.

Excessive volatility in financial markets can disrupt economic activity, affect investor and consumer confidence, and potentially lead to financial crises in an economy. Due to this backdrop, this study examined the link between asset class volatility and the output gap in Nigeria. The asset classes were categorized into stock, crude, gold, and bitcoin. The study adopted the GARCH and Bayesian VAR approach and found that all share index has an initial negative impulse with output gap while other asset classes have a positive impulse on output gap. The outcome of this study revealed to both policymakers and economists the potential risks and vulnerabilities of asset class volatility in the economy. Based on this result, recommendations are made amongst which is the strengthening of the Nigerian stock market to help with the inflationary pressures this is because the Nigerian stock market hurt the output gap also, the government should prioritize investing in crude, gold, and bitcoin to push the actual output to full capacity, which brings about employment.

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.
