The Appalachian Regional Commission’s definition of the Appalachian region is the one used most often by researchers, politicians, and the popular press. The uncritical use of this definition of Appalachia raises issues of both selection bias and excess heterogeneity in regression analysis of...

We measure the effect of resource sector dependence on long run income growth using the natural experiment of variation in coal endowments in a set of 409 relatively U.S. counties selected for homogeneity. Using a panel data set that extends over two separate boom and bust cycles (1970-2010), we...

There is an ongoing literature in economics examining the deterrent effect of police officers on criminal activity. However, this literature tends to focus on the aggregate number of officers employed versus the relative allocation of an officer's time. In this paper, we examine how the...

A consistent finding in health services research is the report of uneven uptake of research findings. Implementation trials have a variable record of success in effectively influencing clinicians' behaviour. A more systematic approach may be to conduct Intervention Modelling Experiments before...

This study applies psychological theory to the implementation of evidence-based clinical practice. The first objective was to see if variables from psychological frameworks (developed to understand, predict and influence behaviour) could predict an evidence-based clinical behaviour. The second...

Premenstrual Syndrome (PMS) is a controversial and ill-defined phenomenon, the aetiology of which remains an enigma, despite considerable research effort. In this paper, four meta-theoretical approaches to PMS are described and evaluated. Approaches to PMS can be criticised on three...

We discuss specification of regression models for using migration data to infer the living standards of different regions, and for observing how much of the standard of living is determined by economic opportunities versus non-pecuniary amenities. We estimate a regression using Canadian data...

Regulation of an industry often produces unintended consequences. Averch and Johnson (1962) argue that certain regulation of electric utilities provides utilities the incentive to purchase an inefficiently large amount of capital. Another possible and related unintended consequence of electric...

We develop and test a model describing the influence of natural gas storage on the electricity forward premium. The model is constructed by linking the effect of gas storage on the higher moments of the distribution of electricity prices to an established model of the effect of those moments on...
