Financial sanctions have economic consequences for the oil-dependent economies. We examined the impact of financial sanctions on exchange rate fluctuations and macroeconomic variables in Iran. To this end, we employed a new Keynesian DSGE model. The results indicated that with the shock in foreign exchange, production (Y) and imports initially decreased. Oil production has shown a positive reaction initially and a negative reaction in the medium term, and after 7 periods, the effect of the shock has disappeared. The capital stock (K) also decreased initially, and in two periods, it reacted positively. In the tenth period, its effect disappeared, and in the long term, it became partially negative, and its effect disappeared. The inflation rate has decreased initially, and its effect disappeared over time. Consumption decreased, and after five cycles, the reaction became positive and then disappeared. The interest rate increased initially and then decreased, and in the 10th period, the shock effect disappeared. The exchange rate initially decreased and then increased after one period.

The development of the nation’s economy is supported by the growing diversity and enthusiasm of interest among academics, particularly in the transforming procedures with an entrepreneurial orientation. The study investigates changing entrepreneurial-oriented practices and the performance of SMEs utilizing a cross-sectional survey amongst the four top grocery registered SMEs operating in Ikorodu local government division of Lagos State, Nigeria. The tool for gathering data is a questionnaire with two sections: bio-data and research questions. While 100 respondents formed the sample size proportionally selected from the study focus. Pearson correlation is the statistical tool for data analysis. The study reveals that creativeness and alleviation of business loss have a highly significant impact on SMEs performance; with pro-activeness having a weak, but positive relevance on SMEs performance. In conclusion, to further improve and optimize entrepreneurial orientation practices and adapt to future threatening changes, firms need to strengthen the desire for healthy competition, identifying and targeting the weaknesses of their competitors. It is recommended that more innovativeness should be sought after as guiding principles for capability and adaptability to handle the complexity of the ever-changing business surrounding, while involvement in risk-taking should be adopted with inevitable zeal and willingness to attain organizational growth and improved performance. Pro-activeness should be given adequate consideration to maintain and surpass existing performance as opportunities come but once. Despite study limitations, future researchers may need to enlarge the sample size and create awareness of research conducted on SMEs generally.

Technological progress has transformed the payment industry. Although alternative payment instruments such as bank cards share some characteristics with banknotes, they are not direct competitors to cash. First, cash possesses unique attributes—its functionality without electrical power and its inherent anonymity. Second, statistical data indicate that the ratio of cash to M1 has stabilized at approximately 10% in recent years, primarily due to its substitution with demand deposits. In this paper, we model the demand for banknotes by incorporating technology-related characteristics alongside conventional theories of money demand. Our approach has important implications for central bank, particularly in liquidity management, currency issuance, effective management of physical currency, and continued investment in digital payment infrastructures. We adopt a macroeconomic perspective that considers banknote demand from both transactional and asset viewpoints. To this end, we estimate an autoregressive distributed lag (ARDL) model, which allows us to analyze both short-term and long-term coefficients within a framework of model uncertainty. A key focus of our study is the estimation of a payment system development index using logistic growth and Gompertz models, through which we assess its impact on cash demand. Our empirical evidence supports the notion of S-shaped growth in the adoption of payment technologies. The findings demonstrate that advancements in the payment sector have led to a significant decline in cash demand. Moreover, while increased real economic activity exerts a positive and significant influence on cash demand, a higher opportunity cost of holding cash has a pronounced negative impact.

The exchange rate is a critical variable that impacts the economy in the international environment. The purpose of this study is to evaluate and compare the two approaches to exchange rate determination outlined in the Law on Permanent Decrees of the Country's Development Programs under economic sanctions. The analysis involves a theoretical discussion of a set of mathematical equations and software results, obtained from the algebraic and numerical solving of a simulated version of a dynamic stochastic general equilibrium model in the context of the international economy for a small open economy. The model is calibrated using the structural parameters of the Iranian economy. The criterion for evaluating the rule and comparing it with other policy options is the "stability" of macroeconomic variables, a key aspect of the Resistive Economy Strategy as the obliging basic document in economic policy-making and planning. The stability is quantified using the "Variance" index. Based on the results of this study, the adoption of the rule-based inflationary exchange rate determination approach, compared with the contingency approach to exchange rate determination, on the one hand, offers the possibility of achieving lower inflation rates and exchange rate growth pace. On the other hand, it will reduce the instability of selected macroeconomic variables, which is desirable from the perspective of the overall policies of the resistance economy strategy. Therefore, it is recommended that, in the presence of foreign economic sanctions, the economic authority should implement inflationary rule of exchange rate determination based on the current inflation rate.

This study explores the considerable significance of candlestick chart patterns as a foundational asset within the realm of stock market analysis and prediction. As a graphical representation of historical price movements and patterns, Candlestick charts offer a distinct and valuable perspective for understanding how the financial market operates. This perspective assists us in accurately pinpointing the most advantageous times for making decisions to buy or sell financial securities, such as stocks or bonds. These charts provide insights into market trends and potential trading opportunities. We adopt an innovative approach by harnessing image processing techniques to extract and analyze patterns from Candlestick charts systematically. Our findings underscore the pivotal role of visual data in financial analysis, particularly in times of market volatility and uncertainty. Investors often resort to technical analysis strategies when confronted with erratic market trends, often relying on insights derived from chart-based analysis to guide their decision-making processes. By meticulously extracting essential insights from candlestick charts, our study aims to provide investors with more efficient and less error-prone tools. Ultimately, this endeavor contributes to the enhancement of decision-making precision and the mitigation of risks inherent in participating in the dynamic stock market landscape.
