Purpose – This paper aims to provide a new quantitative methodology for predicting turning points and trends in financial markets time series based on information-gap decision theory. Design/methodology/approach – Uncertainty in future returns from financial markets is modeled using...

The finite lattice method of series expansions is used to calculate a number of extended series for susceptibilities of the three- and four-state Potts models on the square lattice. We analyse all these series and estimate their critical amplitudes. We resolve an uncertainty in amplitude ratios...

Purpose – The purpose of this paper is to outline a method for evaluating gearing ratios when the loan rate and the rate of growth of the asset value are subject to severe uncertainty. Design/methodology/approach – Gearing ratios often are determined without any explicit methodology to deal...

Purpose – The purpose of this paper is to provide a quantitative methodology based on information-gap decision theory for dealing with (true) Knightian uncertainty in the management of portfolios of assets with uncertain returns. Design/methodology/approach – Portfolio managers aim to...

Purpose – The purpose of this article is to introduce a new method of estimating risk as an alternative to value at risk (VaR), drawing on the risk assessment literature in environmental science. Design/methodology/approach – A commonly used and accepted measure of market risk is VaR,...

"The successful management of transgenic technology is likely to depend on the economic behavioral response of farmers to the regulated use of transgenic crops. A well-studied example is the widespread use of Bt-corn, in the United States, and elsewhere, to control the European Corn Borer, a...
