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...

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...

This study explores the impact of commodity price volatility on external debt accumulation under fixed, managed, and floating regimes. We estimate dynamic panel data models for 97 countries from 1993 to 2016. Our empirical findings show that commodity price volatility increases external debt...

This volume – Predicting Crisis: Five Essays on the Mathematic Prediction of Economic and Social Crises – is the first of three sets of essays. In this first set the economic and social history of the United States is shown to be a “system of movement,” i.e. a logical and mathematic...

This article proposes that Okun’s Law is an empirical relationship between employment and production which, in the United States, correlates to the relationship between the radius of a circle and one-half of its circumference i.e. numerically, the ratio 1 : π. This requires two new sets of...

In Albers & Albers (Spring, 2013) we demonstrated that the historic development of U.S. real GNP, 1869-present, may be structured in recurring 14-year periods. A steady-state rate of growth of 3.4969% is thereby calculated, generating an increase in real GNP proportional to the famous “Golden...

The behaviour of aggregate consumption is conventionally understood from the perspective of the permanent income and life cycle hypotheses. Both of these hypotheses are deduced from the theory of constrained optimization as applied to a ‘representative agent’ that consumes and saves. An...

The thirlwall law is also called the balance of payment constraints model. The basic model is anchored on the dynamic Harrod foreign trade multiplier, which is also known as Thirlwall law or the 45 degree rule, developed through the pioneer efforts of Thirlwall (1979). On the assumption of...

We consider economic agents, agent’s variables, agent’s trades and deals with other agents and agent’s expectations as ground for theoretical description of economic and financial processes. Macroeconomic and financial variables are composed by agent’s variables. In turn, sums of...

This paper presents further development of our economic model. We describe economic and financial transactions between agents as factors that define evolution of economic variables. We show that change of risk ratings of agents as their coordinates on economic space due to economic activity or...
