Interest has been growing in testing for nonlinearity or chaos in economic data, but much controversy has arisen about the available results. This paper explores the reasons for these empirical difficulties. We designed and ran a single-blind controlled competition among five highly regarded...

The macroeconomic concept of "stabilization policy" implicitly assumes that the macroeconomy is unstable without imposition of a policy. Hence selection of a "stabilization policy" can be viewed as selection of a policy to bifurcate the system from an unstable to a stable operating regime. The...

Historically, microeconomics was the domain of scientific methodology in economics, while macroeconomics attracted less mathematically oriented economists. In recent years, the level of sophistication of macroeconomics has grown dramatically, and that field now attracts many of the most...

In specifications of tastes and technology, econometricians often impose curvature globally, but monotonicity only locally or not at all. In fact monotonicity rarely is even mentioned in that literature. But without satisfaction of both curvature and monotonicity, the second order conditions for...

The determinants of money velocity are theoretically explored under various assumptions of interest rate uncertainty in a monetary general equilibrium model. Money is introduced by putting monetary services in the utility function. Monetary assets pay interest. When interest rates are uncertain,...

This paper is an up-to-date survey of the state-of-the-art in dynamical systems theory relevant to high levels of dynamical complexity, characterizing chaos and near chaos, as commonly found in the physical sciences. The paper also surveys applications in economics and finance. This survey does...
