We report results of experiments designed to test the predictions of the best reply process. In a Cournot oligopoly with four firms, the best reply process should theoretically explode if demand and cost functions are linear. We find, however, no experimental evidence of such instability....

The public debt may hamper US GDP say studies that estimate debt tipping effects as if there were a single world currency. This means that such studies ignore the likely biggest cause of changes in growth rates, namely damage from exchange rate liquidity shocks because we do not live in the...

This paper introduces a new theoretic entity, a nominalist heuristic, defined as a focus on prominent numbers, indices or ratios. Abstractions used in the evaluation stage of decision making typically involve nominalist heuristics that are incompatible with expected utility theory which excludes...

The prior paper in this sequel, Pope (2009) introduced the concept of a nominalist heuristic, defined as a focus on prominent numbers, indices or ratios. In this paper the concept is used to show three things in how scientists and practitioners analyse and evaluate to decide (conclude). First,...

The paper re-expresses arguments against the normative validity of expected utility theory in Robin Pope (1983, 1991a, 1991b, 1985, 1995, 2000, 2001, 2005, 2006, 2007). These concern the neglect of the evolving stages of knowledge ahead (stages of what the future will bring). Such evolution is...

A central concern in health economics is to understand the influence of commonly used physician payment systems. We introduce a controlled laboratory experiment to analyze the influence of fee-for-service (FFS) and capitation (CAP) payments on physicians' behaviour. Medical students decide as...

In the evaluation of experiments often the problem arises how to compare the predictive success of competing probabilistic theories. The quadratic soring rule can be used for this purpose. Originally this rule has been proposed as an incentive compatible elicitation method for probabilistic...

Brander and Lewis argue in a seminal paper (AER, 1986) that a firm's debt-equity ratio should have important strategic effects on product market competition. We test their model in a duopoly experiment under both, Bertrand and Cournot competition. We find that leverage has strategic effects, but...
