The IT, the Internet, or the Computing & Communications (C&C) technology revolution has been central to the economic discussion for several decades. Before the mid-1990s the catchword was the “productivity paradox” coined by Robert Solow, who stated in 1987 that “computers are everywhere...

Recent theoretical advances in consumption theory suggest that there may exist predictable consumption surges which, if not taken sufficiently into account in forecasting, may lead to predictable forecast errors. We use this insight to identify economic variables that might help improve the...

We present a non-linear solution method of saddlepoint dynamics in discrete time optimization problems. It is based on the backward attractivity of the stable manifold and is very easy to implement. After an introduction to the general method we present two applications. First we consider the...

A model of cumulative causation is extended to incorporate endogenous structural change. This is achieved via the use of a non-linear feedback of the growth rate on to the income elasticity of demand for exports. The result is a model that, under certain conditions, exhibits chaotic switches...

It is often objected that we cannot use mathematical methods in finance because (1) finance is dominated by unpredictable unique events (the black swans), (2) there are qualitative effects that cannot be quantified, and (3) the laws themselves of finance keep on changing. In this paper we...
