The adoption of inflation targets by a number of industrialised countries in the last decade has reawakened interest in the study of rules to characterise monetary policy. In the literature a clear distinction is drawn between instrument rules, such as that of Taylor, which are backward looking,...

Interval arithmetic and computational (automatic) differentiation are powerful methods for use in optimization. Interval arithmetic operates on interval values rather than points and can be used to examine large areas of a space, often eliminating portions shown not to contain the global...

Here we give a model of co-evolution in a society of economic agents, defined as autonomous software entities equipped with their own utility functions. These utility functions are governed by the market mechanism. We also provide an evolutionary explanation of how social competence that...

This study reports on market power experiments for an agent-based computational model of a labor market. Workers and employers repeatedly choose and refuse worksite partners on the basis of continually updated expected returns, engage in worksite interactions modelled as two-person games, and...

In the stochastic switching regression model, it is not known which of several alternative regression models has actually generated the observed dependent variable. This study develops Bayesian methods for estimating the parameters of this model. A difficulty with this approach in this context...

Here we investigate the selection of an optimal horizon for inflation targeting in the United Kingdom. We examine each of several ways for interpreting optimal horizons. To assess robustness against model uncertainty, we derive results for a set of models „ rather than just one „ having...

Wilkinson Tests are entry-level tests for assessing the numerical accuracy of statistical computations that have been applied to statistical software packages. Some software developers whose products have failed these tests have corrected deficiencies in subsequent versions. Thus, these tests...

A number of test statistics arising in econometrics can be expressed as a weighted ratio of quadratic forms in normal variables (ROQNV), but tractable expressions for computing their pdf and cdf do not exist. A numerical method for evaluating the cdf is given in Imhof (1961) but has the...

We formulate an optimizing-agent model in which both labor and product markets exhibit monopolistic competition and staggered nominal contracts. We demonstrate that the household's unconditional expected utility can be expressed in terms of the unconditional variances of the outgap gap,...

This paper discusses the asymptotic and finite-sample properties of the Efficient Method of Moments (EMM) when applied to estimating stationary ARMA models. Issues such of identification, model selection, and testing are also discussed. The properties of these estimators are compared to those of...
