Implications of Inertia for Assessing Drug Control Policy: Why Upstream Interventions May Not Receive Due Credit

Caulkins, Jonathan - 2007

Background: There is ongoing interest in assessing the effectiveness of various drug control strategies, including policy intended to reduce initiation and prevalence. Compartmental models of trajectories of drug use have been developed that demonstrate that drug “systems” display...

An analysis of future platinum resources, emissions and waste streams using a system dynamic model of its intentional and non-intentional flows and stocks

Elshkaki, Ayman - In: Resources Policy 38 (2013) 3, pp. 241-251

Platinum is increasingly used intentionally and non-intentionally in several applications. This has raised the concern about its future resources, emissions and losses during its life cycle. On the one hand, increasing platinum emissions might affect human health. On the other hand, the...

A tribute to Earl A. Thompson and, in his own words, a summary of his general economic and social theory

Allison, Don; Borcherding, Thomas - In: Public Choice 156 (2013) 1, pp. 7-29

Brilliant but little known, in part because his style was dense and crucial papers unpublished, Earl Thompson reformulated standard theory to achieve policy relevance, focusing on significant rent-seeking inefficiencies stemming from private information and transaction costs. Drawing on history,...
