The study aims to derive the full multipliers of the economic variables that affect income, which are government expenditure, tax, money supply, the general level of prices, the exchange rate, and the lag of income. The reduced form of the income model was used by deriving the total expenditure equation from which the various income multipliers wer...
This paper attempt to assess the impact of the short and long run of devaluation on domestic currency on Sudan's current account over the period (1986-2020). With this objective, the autoregressive distributed lag (ARDL) cointegration test is employed to test the long run relationship hypothesis for the export and import demand functions, in additi...
The study proposes and discusses a model for knowledge production and truth discovery under the rubric of hosting versus control. The proposed model shows that there are two types of knowledge production methods. The first method is to control the phenomenon by studying it by knowing the initial root of the phenomenon or what the study calls a bott...
The study raises a fundamental question: is religion subject to an evolutionary process based on Darwinism, or was it formed in a space outside that? And a subsidiary question that is, are our rational justifications sufficient to establish a disciplined idea of religion, whether positive or negative, or do our minds mislead us? The aim of the stud...
The study aims to compare two based macroeconomic models, which they deal with the phenomena of income. The properties of the two models , one is potential income while the other is reduced form. the former seeking for the maximum potency of the economy, while the later seeking for the first root of the income. The former defined as top to bottom m...
The study proposes and discusses a model for knowledge production and truth discovery under the rubric of accommodating versus control.

The first method is to control the phenomenon by studying it by knowing the first root of the phenomenon or what the study calls a...
The study aims to test the monetary data of Sudan in order to detect whether the petroleum era is totally distinct from the none petroleum era or not. The study had used four discriminant variables which are money multi-plier, velocity of money, monetary deepening and quasi money. The study seeks to know what is the more discrimi-nant variable and...

The problem of this study is seeking to answer the question whether the COVID-19 pandemic has a serious effect on the Saudi economy or not. The main objective of the study is to highlight the degree of the Saudi economic flexibility in response to external shocks by using more frequent method, which is long memory technique, that is suitable in ana...
The problem of this study is how to make a link between four studies, which reflect how they integrated to make one pound study, or how they are aligned together in order to explain and interept the chanalenges facing the sudan economy. So study is aggregation to four studies by using meta-analysis method which is suitable for intergrating studies...
The study focuses on examining the concepts of knowledge, freedom, and subconscious and the interrelation between them. The study uses the results of two economic studies by addressing their implications to the field of knowledge and their connection with freedom and consciousness. The main objective of the study is examining the relationship betwe...
This paper aims to develop a mathematically reduced-form model to analyse
and interpret business cycle fluctuations and their consequences on economic
stability. The proposed model utilises national income identity and a set of six
behavioural equations including consumption, investment, taxes, money
demand, exports and imports. Using the tools of...
This study attempts to answer the main question: are there reciprocal effects between the variances of the stock returns in the Saudi market, also the answer to a sub-question. What are the leading stocks in the Saudi market?. Study selected a sample of five stocks representing the basic materials, banking, services, food and transport sectors (SAB...
In this study Sudanese commercial bank was examined through generalized regression models namely, fixed effect and random effect. The model incorporated two explanatory variables particularly assets and liabilities as main variables in explaining the profitability , more over three additional dummy variables were introduced as explanatory variables...
Estimating economic relations through model system is valuable, hence this study tackled the system of exchange rate as a part of Sudan economy model in order to provide key tools to the policy makers which can help in managing macroeconomic objectives. The suggested system of exchange rate comprise from five equations which are well identified. Ap...
Dynamic analysis is vital issue in econometrics, hence we were applied it to model and estimate exchange rate. The study variables covers the proxies of fiscal, monetary , and mixed policy. Furthermore GDP is introduced to reflect the overall performance of the economy. Some variables were stationary while Cointegration tests confirmed the existenc...
This study attempts to answer whether there is an interaction and volatility between the variances of the stock returns in the Saudi market. The sample represents daily stock prices of five sectors i.e. basic materials, banking, services, food, and transportation (SABIC, Al Rajhi, Etisalat, Almarai, and Al Bahri, respectively) from 2011 to 2016. Th...
The study raised the question of knowledge generation, in attempt to answer this question an economic model was introduced, namely, aggregate demand and aggregate supply. The final target equations can be solved by general rule (deterministic) of solving quadratic equations. The study use analytical geometry and matrix algebra tools to solve the mo...
This study asks about the existence of co-variances and correlations among variances in the Saudi stock returns and aims at knowing which stocks are the most closely related to other stocks. A sample of five stocks representing basic materials, banking, services, food and transport sectors and reflecting the main trends in the Saudi market were sel...
The main objective of this study is to know whether short and long run relationships exist between stock values in the Saudi market. For that purpose,
the authors extracted daily stock value data from five distinct Saudi economic sectors. Using modern statistical techniques through MGARCH (DVEC)
and error correction models, the authors estimated th...
This study aims to estimate the volatility of exchange rate through applying the GARCH model method which is appropriate in such cases. The study used symmetric and a symmetric model to the data of exchange of Sudan comparing two periods after and before separation of the country. The study found that the first period which is before separation is...
Macroeconomic indicators like inflation, unemployment as well as payment balance influence by national income level and growth. To manage macro indicators ought to compromise national income growth. Hence factorization of income helps in assessing these indicators beside achieving their target levels. This study approaching national income through...
This paper explores the role of private health insurance (PHI) in Gulf Cooperation Council states (GCC). It is assumed that the GCC states share similar characteristics and policy challenges for the effective integration of private insurance into national health care systems where there is a projected strong growth of PHI that needs to be accompani...
The study focusing in formulating an accurate mathematical formula that calculates precisely the internal rate of return.
