Gradient methods have been useful in economics, particularly in non-linear programming and estimation. This paper outlines a gradient model of dynamic consumer behaviour under uncertainty. An extension to a two-consumer bargaining model is suggested. A key role is played by the nature and extent...

Aaron and McGuire recently put forward a new method for imputing benefits of government expenditures on public goods for various income classes. They fail to present conclusive empirical results, however, lacking a parameter whose value is heretofore unmeasured. This note uses three independent...

Frank Bechling recently wrote that "the concentration on the trade-off between unemployment and inflation and the neglect of trade-offs between unemployment and other variables (balance of payments, economic growth, structural change, and income distribution) may lead to a suboptimal choice...

New operational definitions of incremental innovation, standard innovation, and radical innovation, are constructed using our ‘technometric benchmarking’ model. Based on this definition, optimal incremental innovation is formulated as a linear programming problem. The model is illustrated by...

How efficiently do countries translate scientific and technological excellence into export comparative advantage? Here the use of science and technology in generating exports is first modelled as a two-stage process. A variant of linear programming (data envelopment analysis, DEA) is then...
