In a plural form, two or more organisational arrangements possess a synergism when used simultaneously. For example, rather than specialising, many chains contain a large proportion of both franchised and company-owned stores. By franchising some stores while they own others, franchise systems...

In the evolutionary setting for a financial market developed by Blume and Easley (1992) the author considers an infinitely repeated version of a model B la Grossman and Stiglitz (1980) with asymmetrically informed traders. Informed traders observe the realisation of a payoff relevant signal...

This paper This paper develops a new approach to the problem of testing the existence of a long-run level relationship between a dependent variable and a set of regressors, when it is not known with certainty whether the underlying regressors are trend- or first-difference stationary. The...

The aim of this paper is to test the performance of the standard version of CAPM in an evolutionary framework. We imagine a heterogeneous population of long-lived agents who invest their wealth according to differential porfolio rules and ask what is the fate of those who happen to behave as...

The authors examine the implications for the optimal interest rate rule that follow from relaxing the assumption that the policy-maker's loss function is quadratic. They investigate deviations from quadratics for both symmetric and asymmetric preferences for a single target and find that (i)...

In econometric analysis, non-nested models arise naturally when rival economic theories are used to explain the same phenomenon, such as unemployment, inflation or output growth. The authors examine the problem of hypothesis testing when the models under consideration are ‘non-nested’ or...

This paper provides a general framework for aggregating linear dynamic models by deriving the aggregate model as an optimal prediction of the aggregate variable of interest with respect to an aggregate information set generated by current and past values of available aggregate observations. The...

This paper considers information criteria as model evaluation tools for nonlinear threshold models. Results concerning the consistency of information criteria in selecting the lag order of linear autoregressive models are extended to nonlinear autoregressive threshold models. Extensive Monte...

(1) The authors solve a two-stage model of electricity trading, with a forward market and a pay-bid balancing mechanism. They derive balancing mechanism strategies for generators which have sold forward and been scheduled to run, and for those which have not. Given these strategies, we can...

How many international agreements should there be, and who should sign them? When policy issues are separable, linking them in a ‘grand international agreement’ facilitates policy cooperation by reallocating slack enforcement power. When policy issues are substitutes, issue linkage further...
