Proposes an economic-growth model that adheres to the salient features of the European economies during the millennium prior to the Industrial Revolution and shows how the Industrial Revolution, generated by the model, can be conceptualized as an escape from the Malthusian trap.

Develops a model that can reproduce the basic features of the European state-system based on the assumption that wars farther removed from the center of power are more difficult to win.

We aim to shed light on the debate among policy-makers trying to find prescriptions that will take troubled economies out of their debt trap. We do this with a highly stylized two-compartment dynamic model consisting of the stocks of money in Government and Society. The dynamics of the system...

Le Bras Hervé and Artzrouni Marc. ? Interference, indifference and independence. Interference in demographic phenomena can be dealt with in two different ways, either by assuming the indifference of the two phenomena or by adopting the Markovian method of multiple decrement. An examination of...

We explore sustainable paths out of a debt trap with a highly stylized two-sector differential equations model for the stocks of money in Government and Society. The model fits the data for the U.S. between 1981 and 2012 with a coefficient of correlation of 0.996. The solutions provide detailed...

Artzrouni Marc. ? A new family of growth curves : application to the demographic transition. The demographic transition is characterized by birth and death rates that decrease from one asymptotic value to the other. These rates can be approximated by "antilogistic" » functions, i.e. "a constant...

A first order linear differential equation is used to describe the dynamics of an investment fund that promises more than it can deliver, also known as a Ponzi scheme. The model is based on a promised, unrealistic interest rate; on the actual, realized nominal interest rate; on the rate at which...
