Various plants and resources such as orchards are vulnerable to the detrimental effects of successful invasions by alien animal or plant species. To outline an appropriate policy response, we first use renewal theory to construct a stochastic model of optimal orchard management in the presence...

This paper introduces and surveys ecological-economic analysis and valuation of biodiversity. Furthermore, the notion and application of economic, monetary valuation of biodiversity is critically evaluated. A classification of biodiversity values is offered, based on a system of logical...

We build quadratic labor adjustment costs into an otherwise standard New-Keynesian model of the business cycle and show that this is sufficient to increase both, output and inflation persistence.
