The public trust doctrine is an ancient doctrine of public property law that governs sovereign stewardship of natural resources. The doctrine both promote public access to trust resources and requires sovereign protection of them for the benefit of the public, including future generations. The...

This paper proposes that, when modeling for the relation between the convenience yield and current scarcity, time to maturity and time to harvest should interact with current scarcity, i.e. the two should enter multiplicatively. In implementing this idea we also compare three models for current...

This article applies public choice political theory to public lands decisionmaking and concludes that it explains why multiple-use management, the paradigm for most federal public lands, consistently overemphasizes commodity production at the expense of other values like watershed protection and...

Stochastic production frontier models are used extensively in the agricultural and resource economics literature to estimate production functions and technical efficiency, as well as to guide policy. Traditionally these models assume that each agent's production can be specified as a...

This paper considers those sectors of the economy that operate under the same regimes of rewarding private innovators as others, but differ in that they face recurring problems of resistance, as occur in the pharmaceutical and agricultural industries. This recurrence originates in the natural...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

We develop a variation of the Grossman-Helpman Protection for Saleʺ model, where organized groups, representing various sectors of the economy, influence government policy. In particular, this paper focuses on the rise of food prices and a greater level of influence of a food sector lobby,...

In the search for effective pesticide risk management tools, the design of pesticide risk indicators is nowadays receiving increasing attention as a complement to more established regulatory strategies. In the present paper, we apply some recently developed pesticide risk indices and test their...

Motivated by the conclusions from various modelling studies, modifications to the bioenergy sector regulations are under way in Europe and in the USA to account for emissions from indirect land-use change (ILUC). Despite their influence on the policy-making, evaluations of the capacity of...

We examine co-movements between biofuels (ethanol and biodiesel) and a wide range of commodities and assets in the USA, Europe, and Brazil. The main contributions are twofold. First, we analyze a unique dataset of 32 commodities and relevant assets (between 2003 and 2015) which is unprecedented...
