We argue that the Soros account of reflexivity does not provide a clear-cut distinction between a social science such as economics and the physical sciences. It is pointed out that the participants who attempt to learn from refutations of conjectures in the Soros world are likely to be haunted by the Duhem–Quine problem of conjointness of hypotheses and unfocused refutation. On a more constructive note, we argue that models of inductive learning, in which participants form conjectures on the… Expand
Dynamic Model of Optimal Production Control in a Hysteretic Behaviour of Economic Agents
The hysteresis nature of demand, depending on the price ratio and purchasing power, is well-known, but mathematical models that describe this relationship have not been developed so far. This articleExpand
Realization of Arbitrary Hysteresis by a Low-dimensional Gradient Flow
We consider gradient systems with an increasing potential that depends on a scalar parameter. As the parameter is varied, critical points of the potential can be eliminated or created throughExpand
Dynamics of Discrete Time Systems with a Hysteresis Stop Operator
TLDR
A piecewise linear two-dimensional dynamical system that couples a linear equation with the so-called stop operator is considered, motivated by modifications to general-equilibrium macroeconomic models that attempt to capture the frictions and memory-dependence of realistic economic agents. Expand

TLDR
It is the wish of the author to keep general terms distinct from abstract singular terms, so that the over-all dis­ pensability of some assumption that has always rankled as ad hoc and unintuitive is discovered. Expand
