The theory for a general equilibrium ecosystem model that can include large number of interacting species is presented. Features include: 1) individual plants and animals are assumed to behave as if they are maximizing their net energy intake, 2) short and long-run equilibriums are obtained, 3)...

We present a model of a multi-species fishery and show that (i) consumer preferences for seafood diversity may trigger a sequential collapse of fish stocks under open-access fishery, (ii) the stronger the preferences are for diversity the higher is the need for coordinated multi-species...

Two agents possess the fishing rights to a lake. Each period they have two options, to catch without restraint, e.g., to use a fine-mazed net, or to catch with some restraint, e.g., to use a wide-mazed net. The use of a fine-mazed net always yields a higher immediate catch than the alternative....

In this study, we examine the differences in preference for renewable resources that arise as a result of the production locale; with the focus on the fish in individual nation's territorial waters, lakes and ponds etc. In addition, we look at incomplete regulation which often occurs in renewable...

Using differential games, this paper analyzes output controls of internationally shared renewable resources such as transboundary natural forests. A two-country, two-good (that is, shared-resource and nonresource based goods) general equilibrium trading model is employed for this purpose. Each...

We present a model of a multi-species fishery and show that (i) consumer preferences for seafood diversity may trigger a sequential collapse of fish stocks under open-access fishery, (ii) the stronger the preferences are for diversity the higher is the need for coordinated multi-species...

William Forster Lloyd's 1833 sketch about poor cattle on the commons and the well-fed animals on the adjacent enclosures published in his "Two lectures on the checks to population" has hitherto been assessed as one starting point of the economics of renewable resources. In the 20th century the...

The literature on trade in renewable resources implicitly assumes that the traded resources are perfect substitutes. We model trade in renewable resources as stipulated not only by autarky price differences, but also by consumers' love of variety. We show that the love-of-variety effect enables...

Risk of stock collapse is a genuine motivation for cooperative fisheries management. We analyse the effect of an endogenously determined risk of stock collapse on the incentives to cooperate in a Great Fish War model. We establish that equilibrium harvest strategies are non-linear in stock and...
