The economic and financial variables of economic agents determine macroeconomic variables. Current models consider agents’ variables that are determined by the sums of values and volumes of agents’ trades during some time interval Δ. We call them first-order economic variables. We describe...

In this study, we evaluate the effectiveness of three popular econometric models ARIMA, MIDAS, and VAR for forecasting quarterly GDP in Madagascar. Our analysis reveals that ARIMA provides the most accurate forecasts among the three models, indicating its superiority in predicting the...

By utilizing the Fixed effect and GMM estimators for a sample of 57 Islamic banks and 102 conventional banks from 10 countries for the period 2002–2018, we examine the effect of the audit committees' and Sharia committees' effectiveness on the bank risk-taking behavior and its transmission...

Thomas Piketty stated that widening economic inequality is an inevitable consequence of free-market capitalism, in which the rate of return (r) on capital (K) exceeds the rate of economic growth (g): r g. Five System Dynamics models are developed to understand the underlying structure that...

The research examines Saudi Arabia's foreign policy against the background of the Syrian conflict. It focuses in particular on religious and historical backgrounds, which are of great importance for understanding developments in the Middle East. Saudi Arabia's changing role in a region that has...

We propose a scenario for computing the real gross domestic product in a macroeconomic framework. The scenario is designed upon simple assumptions while ensuring basic algebraic relationships between the four usual macroeconomic accounts.

This paper develops a dynamic general equilibrium (DGE) model to assess the impact of AI-driven automation on labor and capital allocation in an economy. The model considers the endogenous response of firms to task automation and labor substitution, showing how the increasing use of AI affects...

We develop an endogenous growth model where data drives innovation. In this model, big data fosters quality improvements by influencing the likelihood and magnitude of successful quality-enhancing innovations. It also promotes variety innovation through the efficient allocation of labor as a...

We develop an endogenous growth model incorporating the spirit of capitalism and examine how it influences innovation and economic growth. In the benchmark homogeneous-ability model, we find that the spirit of capitalism increases both the capital accumulation rate by enhancing consumer patience...

This contribution to the conference "Nach der Wertdiskussion?" of the Political Economy Research Group of the Philipps University of Marburg, which took place on 27 and 28 June 1998, analyses the "core" of the neo-Ricardian model, i.e. the mathematical approach underlying the determination of...
