RESOURCE OR NUISANCE? MANAGING AFRICAN ELEPHANTS AS A MULTI-USE SPECIES
Provedor de dados: 31
Autores: Horan,   Richard D.; Bulte,   Erwin H.
Increasing human interference with natural systems causes us to re-think our perception of wildlife species and the economic choices society makes with regards to their management. Accordingly, we generalize existing ‘'bioeconomic' models by proposing an economically-based classification of species.  The theoretical model is applied to the case of African elephant management.  We demonstrate that the classification of the steady state population of a species depends on both species' density and economic factors.  Our main results are threefold.  First, we demonstrate the classification-dependent possibility of multiple equilibria and perverse comparative statics for multi-use species. Second, upon comparing the optimal stock of a multi-use species to the...

Coevolutionary Investments in Human Speech and Trade
Provedor de dados: 31
Autores: Bulte,   Erwin H.; Horan,   Richard D.; Shogren,   Jason F.
We propose a novel explanation for the emergence of language in modern humans, and the lack thereof in other hominids.  A coevolutionary process, where trade facilitates speech and speech facilitates trade, driven by expectations and potentially influenced by geography, gives rise to multiple stable development trajectories.  While the trade-speech equilibrium is not an inevitable outcome for modern humans, we do find that it is a relatively likely result given that our species evolved in Africa under climatic conditions supporting relatively high population densities.

Competitive Exclusion, Diversification, and the Origins of Agriculture
Provedor de dados: 31
Autores: Horan,   Richard D.; Shogren,   Jason F.; Bulte,   Erwin H.
The beginnings of agriculture, or the agricultural revolution, is now recognized to be the widespread adoption of known practices – a change in behavior – as opposed to a phenomenon of discovery and innovation.  In this paper, we combine elements of three theories—climate change, property rights, and competitive exclusion—to create a paleoeconomic model of agriculture and its diffusion.   We focus on climate change as a necessary trigger, which combined with group property rights and competitive exclusion processes produced conditions sufficient for the diffusion of early agriculture. In contrast to other models in which farming emerges as technological progress or climate makes it a more productive option than hunting, farming emerges in our model even if...

COMPENSATION FOR WILDLIFE DAMAGE: HABITAT CONVERSION, SPECIES PRESERVATION AND LOCAL WELFARE
Provedor de dados: 31
Autores: Rondeau,   Daniel; Bulte,   Erwin H.
We study the environmental and economic consequences of introducing a program to compensate peasants of a small economy for the damage caused by wildlife. We show that the widely held belief that compensation induces wildlife conservation may be erroneous. In a partially open economy, compensation can lower the wildlife stock and result in a net welfare loss for local people. In an open economy, compensation can trigger wildlife extinction and also reduce welfare. The conditions leading to a reduction of the wildlife stock are identified and the implications for current and planned compensation programs are discussed.

A NOTE ON HIGH DISCOUNT RATES AND DEPLETION OF PRIMARY FORESTS
Provedor de dados: 31
Autores: Bulte,   Erwin H.; van Soest,   Daan P.
Conventional wisdom implies that high discount rates accelerate depletion of tropical forests. As shown in this article, this result does not necessarily hold in a two-state variable model that distinguishes between primary and secondary forest stocks. In the context of a fixed concession period and imperfect government control, logging of primary forests may be both accelerated and depressed as discount rates increase.

Resource Abundance, Poverty and Development
Provedor de dados: 31
Autores: Bulte,   Erwin H.; Damania,   Richard; Deacon,   Robert T.
The negative correlation between resource endowments and GDP growth remains one of the most robust findings in the empirical growth literature, and has been coined the “resource curse hypothesis”.  The policy consequences of this result are potentially far reaching.  If natural resources are an inescapable curse, this may imply that countries richly endowed with natural resources can only develop by turning their backs on their comparative advantage and diversifying into other non-resource based activities. This paper analyzes whether the negative statistical relationship between natural resource abundance and economic growth spills over to other important economic and social indicators.  The impact of resource wealth on several proxies of economic...

BANKING ON EXTINCTION: IVORY STORAGE AND ELEPHANT CONSERVATION
Provedor de dados: 31
Autores: Bulte,   Erwin H.; Horan,   Richard D.; Shogren,   Jason F.
Ivory poachers threaten the half million remaining African elephants.  In response, Kremer and Morcom (2000) offer a novel solution to reduce the risk of extinction -- a local government can stockpile ivory and threaten to dump it on the market if the elephant population falls too low lowering the expected returns from ivory sales and driving poachers out of business).  We show that ivory stockpiling could be detrimental to elephant conservation because large stocks create strong incentives for strategic extinction by African governments.  This result suggests an alternative strategy to enhance the viability of African elephant stocks -- international conservation organizations rather than governments should hold the stockpiles.

Horticultural Households Profit Optimization and the Efficiency of Labour Contract Choice
Provedor de dados: 31
Autores: Ndoye Niane,   Aifa Fatimata; Burger,   Kees; Bulte,   Erwin H.
In agriculture, the coexistence of different forms of land tenancy or labour contract has been explained so far by several theories related to Marshallian inefficiency, incentives, risk sharing, and transaction costs, including supervision costs. These theories and the empirical evidences have greatly contributed to explain the reasons behind land tenancy or labour contract choice. This study follows up on this. Moreover, it intends to take a further step by focusing particularly on the production technologies at plot level, and by designing and testing a theoretical model based on household profit optimization. This model will take into account the supervision costs of labour (i) to compare optimum profit derived from plots based on household labour, a...
