This paper focuses on induction, because the supposed weaknesses of that process are the main reason for favouring falsificationism, which plays an important part in scientific methodology generally; the paper is part of a wider study of economic methodology. The standard objections to, and...

Fuzzy logic and genetic algorithms are used to rework more realistic (and more complex) models of competitive markets. The resulting equilibria are significantly different from the ones predicted from the usual static analysis; the methodology solves the Walrasian problem of how markets can...

This paper examines the role that weight restrictions play in Data Envelopment Analysis (DEA). It is argued that the decision to include a factor (input or output) in a DEA model represents an implicit judgement that the factor has a non-trivial weight. It therefore seems perverse to allow DEA...

The pursuit of equity of access to health care is a central objective of many health care systems. This paper first sets out a general theoretical framework within which equity of access can be examined. It then applies the framework by examining the extent to which research evidence has been...

The Euler equation model is used to determine the fraction of consumers who are liquidity constrained in ten Asian developing countries. Our estimates of the fraction of liquidity constrained consumers range between 0.5 and 0.9. We further investigate whether financial liberalization has...

The mean variance efficiency (MVE) of a portfolio of international bonds and equities is tested using a CAPM model of excess returns. The conditional variances and covariances of the portfolio returns are allowed to time-vary according to shocks in up to three global macro-economic variables...
