One of the surprising features of modern economic growth is that economies abundant in natural resources have tended to grow slower than economies without substantial natural resources. In this paper we show that economies with a high ratio of natural resource exports to GDP in 1970 (the base year) tended to grow slowly during the subsequent 20-year period 1970-1990. This negative relationship ...

We extend Real Option Theory to evaluate natural resource development projects that may bring negative net bene ts and require costly restoration. Based on a new concept, irreversibility cost, we show that the degree of irreversibility becomes an endogenous choice, rather than an exogenously given economic constraint. The xed cost of restoration has continuous impacts, over and above the widely...

With huge amounts of information connected to the global information network (Internet), e cient and e ective discovery of resources from the \global information base" has become an imminent research issue, especially with the advent of the Information Highway. This article proposes the use of novel Arti cial Intelligence and Database techniques (Assumption Grammars, Concept Hierarchies, Multi-...

In 1971, I spent five months in Ghana, West Africa, collecting data for an MSc thesis, "On the Ecology and Fishery of a Small West African Lagoon". I was puzzled at the time by the behavior of the fishermen who exploited the Sakumo lagoon, near Tema (Fig. 1). Based in a nearby village, they were part-timers or full-timers, but fished in either case rarely more than about 4 hours at a time, then...

Operations research is becoming increasingly prevalent in the natural resource sector, specifically, in agriculture, fisheries, forestry and mining. While there are similar research questions in these areas, e.g., how to harvest and/or extract the resources and how to account for environmental impacts, there are also differences, e.g., the length of time associated with a growth and harvesting ...

Why does conflict occur over the use of natural resources? How are external factors built into local conflicts? What governing mechanisms are conducive to equitable and sustainable natural resource management by communities? When do local strategies for conflict management need to be complemented or replaced by external or new mechanisms? How can research help identify opportunities for turning...

The purpose of the study was to verify, through the use of an experimental method, the assumption that the ‘economic human’ pays more attention to the externality he/she causes as the strength of externality increases. We used a social-experiment design within an undergraduate classroom to test assumptions, using statistical method. A lakeside plant was used as an example. Our results confirmed...

entrepreneurship willingness that is one of the main preconditions of entrepreneurship behavior is influenced by psychological factors. accordingly, the main purpose of this study was to investigate relationship between problem solving styles and entrepreneurship willingness among agricultural and natural resource students, in university of zabol. the statistical population consisted of 3000 ag...
