The discrete schemes, which are implicit two-point block methods, are obtained by carefully and unevenly choose collocation points that ensure better methods’ stability via test. However, these schemes require seventh derivative functions unlike other existing numerical formulae. The new methods are found, investigated and proven to be convergent and A-stable. The implementation of methods is achieved by using Newton Raphson’s method. Experiments show the efficiency and accuracy of the developed formulae on different class of first-order initial value problems, including SIR, growth models and Prothero-Robinson oscillatory problem and with comparison to such existing methods. In addition, it is observed that uneven and positioning of collocation points greatly influence the efficiency and accuracy of numerical methods.\u0000","PeriodicalId":500839,"journal":{"name":"Qeios","volume":"184 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140235686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study employed a causational research design by utilizing data from 2011–to 2021. The study unit of analysis is 15 Commercial banks in Ethiopia. It utilized General Methods of Moment (GMM) dynamic panel regression.The finding showed that bank profit, interest rate margin, concentration ratio, and inflation havesignificantly negatively contributed to bank liquidity. However, capital adequacy has no significant effect on the bank's liquidity. Besides, the growth of the Gross domestic product and exchange rate significantly enhance the bank's liquidity. The study urges the bank management and regulatory body to search for the optimum trade-off point between profit and interest rate spread with the required level of liquidity. Besides, policymakers and regulators should take a measure that neutralizes the detrimental effect of the market structure of the banking industry. Since inflation and money supply (M2) negatively affect liquidity, it is vital to transform macroeconomic variables into a robust institutional mechanism to enhance liquidity. Generally, the study recommends continued supervision and support to shield banks from a liquidity crunch.\u0000","PeriodicalId":500839,"journal":{"name":"Qeios","volume":"76 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140242375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examine the effects of the invest-to-deposit ratio (IDR) by financial institutions, market interest rate (MKTINT), and Consumer Price Index (CPI) on market capitalization (MAKTCAP). This study utilizes a dataset spanning 83 months, encompassing the period from 2015 to 2021. The macroeconomic influence is examined empirically by using the Arellano–Bover/Blundell–Bond generalized method of moments (GMM) estimator, supplemented by the ordinary least squares (OLS) and weighted least squares regression (WLS). Also, use Breusch-Pagan and Cook-Weisberg tests to measure heteroskedasticity in the model. The findings show a strong correlation between IDR and MAKTCAP, pointing to IDR as the most important yet overlooked factor influencing capital market returns. However, MKTINT and CPI results address a negative relationship with MAKTCAP. Higher IDR indicates that the capital market receives more cash flow to enhance market capitalization. At the same time, lowering MKTINT and CPI enables the capital market to get more money flow.\u0000","PeriodicalId":500839,"journal":{"name":"Qeios","volume":"60 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140242464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
