The increase in energy prices between 2004 and 2007 has several potential consequences for aggregate agriculture in the U.S. We estimate the derived input demand elasticities for energy as well as capital, labor, and materials using the differential supply formulation. Given that the derived...

This paper fills the gap of modeling positive externality cases when private marginal cost is higher than social marginal cost. Within this unique type of divergence of marginal costs two cases are scrutinized: social marginal benefit being higher than private marginal benefit, and vice versa,...

Non market valuation and bio economic modelling are combined in a dynamic model of ecosystem services. A mathematical proof demonstrates that the imputed price of natural capital contains all non market values and that scarcity rent is the total value of ecosystem services. A dynamic demand...

This paper reports on a case study to establish dollar values for loss of biodiversity in the New Zealand coastal marine environment. The study uses the European Shore Crab (Carcinas maenas) as the example alien invasive species and the Pauatahanui Inlet, Wellington, New Zealand, as the...

Governments are under increasing pressure to deliver results. Therefore, it is important to evaluate the effectiveness, efficiency and relevance of the public service in implementing policies and programmes for social betterment. Without such evaluations, it is difficult to ensure that evidence...

Röling and others argue that research and extension should not be seen as separate processes involving distinct institutions which must somehow be linked. Rather, scientists, specialists, extension workers, consultants and producers should be seen as participants in a single agricultural...

Ricecheck, an extension program for rice developed by the NSW Department of Primary Industries, is based on eight best management practice recommendations (“key checks”) considered essential for achieving high yields. The program comprises grower meetings and field days. The Ricecheck...

Several trials have recently taken place in Australia of sealed bid discriminant price auctions for conservation contracts. The trials encourage landholders to competitively tender for funds to provide conservation actions on private land. In these auctions, environmental benefits of offers are...

Global climate anomalies affect world economies and primary commodity prices. One of the more pronounced climate anomalies is El Niño Southern Oscillation (ENSO). In this study I examine the relationship between ENSO and world commodity prices using monthly time series of the sea-surface...

Greater understanding of irrigator water trade decision-making processes provides insight into the efficient reallocation of water resources between competing uses. Water trade decisions are often modelled as single processes, although results in this paper suggest that sequential decision...
