Última ALLOCATING BIOSECURITY RESOURCES IN SPACE AND TIME AgEcon Cacho, Oscar J.; Hester, Susan M.. Invasive species can cause significant damage to natural environments, agricultural systems, human populations and the economy as a whole. Biological invasions are complex dynamic systems which are inherently uncertain and their control involves allocation of surveillance and treatment resources in space and time. A complicating factor is that there are at least two types of surveillance: active and passive. Active surveillance, undertaken by pest control agencies, has high sensitivity but generally low coverage because of its high cost. Passive surveillance, undertaken by the public, has low sensitivity and may have high coverage depending on human population density. Its effectiveness depends on the extent to which information campaigns succeed in...

Ano: 2011 URL: http://purl.umn.edu/100535 A Search Model for Joint Implementation AgEcon Bella, Giovanni. The aim of this paper is to present a search model in the field of environmental economics, where so-called clean and dirty producers enter the trading market, both looking for a partner with whom to exchange the goods they are endowed with. The model derived in this paper is rather simple. Nevertheless, it is able to produce a series of interesting results and useful insights, and is conveniently used here as a framework to explain the functioning of Joint Implementation programmes for polluting emissions’ reduction.

Ano: 2009 URL: http://purl.umn.edu/54356 Weed Search and Control: Theory and Application AgEcon Cacho, Oscar J.; Spring, Daniel; Pheloung, Paul; Hester, Susan M.. The detectability of invasive organisms influences the costs and benefits of alternative control strategies, and the feasibility of eradicating an infestation. Search theory offers a mathematically rigorous framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. To demonstrate the application of search theory to invasive species control, invasive species detectability is incorporated into a population simulation model. The model is applied to a base set of parameter values that represent reasonable values for a hypothetical weed. The analysis shows the effects of detectability and search time on the duration of an eradication program. Furthermore, for a given level of...

Ano: 2004 URL: http://purl.umn.edu/12919 EFFECTIVENESS OF USE-VALUE ASSESSMENT IN PRESERVING FARMLAND: A SEARCH-THEORETIC APPROACH AgEcon Tavernier, Edmund M.; Li, Farong. Search theory is used to present a theoretically defensible model to examine the effectiveness of use value assessment (UVA) in preserving farmland. The model is empirically tractable and supports the findings of past research. The analysis considers the impact of farm income, uncertainty, and the distribution of the offer price on the effectiveness of UVA in preserving farmland and shows, through the effect on the reservation price, that for a given distribution of the offer price, property-tax rate, and the difference between market-value and use-value of land, the preservation of agricultural land only takes place within a relevant range.
