Economic growth and unemployment exhibit an ambiguous relationship – according to empirical studies. This ambiguity can be investigated by observing the role of the underground economy in shaping the productivity of firms. Indeed, unemployment may be absorbed by underground firms, which adopt...

This set of three volumes argues that the mind – human consciousness – may be measured by considering mathematically the aggregate of that consciousness, i.e. social history. From this beginning theme of discussion three questions must arise. 1. How might this measurement be made? 2. Of what...

I argue that a form of consciousness may be found in American economic history, one which is both mathematically demonstrable and important. In this book I present a model of economic and political growth based upon systematic addition. We begin with a philosophic model of trade (pp. 34-46);...

“Okun’s Law” states a 3:1 proportion between percent growth in U. S. real GNP and percent decrease in the rate of unemployment. This paper argues that this ratio is actually a Pi:1 proportion, heretofore unrecognized because it is displayed through a form of mathematic / harmonic inverse....

In sum, in these essays I explore the self-similarity between levels, the fractal structure of reality, through an investigation of an inherent and unavoidable uncertainty which is unique to each level. These essays will demonstrate that as each level struggles to resolve its own inherent...

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...

We present a comprehensive macroeconomic model for the U.S. There exist strict long-term relations between real GDP, price inflation, labor force participation, productivity, and unemployment. The evolution of real GDP depends only on exogenous demographic forces. Other macro-variables follow up...

We have modeled the employment/population ratio in the largest developed countries. Our results show that the evolution of the employment rate since 1970 can be predicted with a high accuracy by a linear dependence on the logarithm of real GDP per capita. All empirical relationships estimated in...

The desired professional insertion (placement) after training is under the influence of personal and exogenous variables. In the present paper we identify the constraints and devices that, in an interactive way, can shape and affect the professional insertion. This paper is a result of a...

A linear and lagged relationship between inflation, unemployment and labor force change rate, π(t)=A0UE(t-t0)+A1dLF(t-t1)/LF(t-t1)+A2 (where A0, A1, and A2 are empirical country-specific coefficients), was found for developed economies. The relationship obtained for France is characterized by...
