The paper considers the use of artiï¬cial regression in calculating different types of score test when the logâˆ'likelihood is based on probabilities rather than densities. The calculation of the information matrix test is also considered. Results are specialised to deal with binary...

Abstract: Vector Autoregressive Moving Average (VARMA) models have many theoretical properties which should make them popular among empirical macroeconomists. However, they are rarely used in practice due to over-parameterization concerns, difficult - ties in ensuring identification and...

This article analyses negative externalities that policy makers in one region or group may impose upon the citizens of neighbouring regions or groups. These externalities may be material, but they may also be psychological (in the form of envy). The latter form of externality may arise from the...

This paper publishes the hitherto unpublished correspondence between Allyn Abbott Young’s biographer Charles Blitch and 17 of Young’s former students or associates. Together with related biographical and archival material, the paper shows the way in which this adds to our knowledge of...

In his new book Professor Muhammad Yunus, Grameen Bank founder and Nobel Peace Prize Laureate, proposes a novel strategy for the elimination of poverty worldwide. This strategy relies on the presumed effectiveness of what he calls “social business” in transforming the nature of the...

This paper uses data on the worldÂ's copper mining industry to measure the impact on efficiency of the adoption of the ISO 14001 environmental standard. Anecdotal and case study literature suggests that fiÂ…rms are motivated to adopt this standard so as to achieve greater efficiency through...

VAR methods have been used to model the inter-relationships between inflows and outflows into unemployment and vacancies using tools such as impulse response analysis. In order to investigate whether such impulse responses change over the course of the business cycle or over time, this paper...

This paper introduces a new model of trend (or underlying) inflation. In contrast to many earlier approaches, which allow for trend inflation to evolve according to a random walk, ours is a bounded model which ensures that trend inflation is constrained to lie in an interval. The bounds of this...

In this paper, we forecast EU-area inflation with many predictors using time-varying parameter models. The facts that time-varying parameter models are parameter-rich and the time span of our data is relatively short motivate a desire for shrinkage. In constant coefficient regression models, the...
