Management Of Fisheries In Eu: A Principal-Agent Analysis, Frank Jensen, Niels Vestergaard

Niels Vestergaard

In this paper, an EU tax on fishing effort is studied as an alternative to the system of Total Allowable Catches (TACs). The analysis is conducted under imperfect information, and the hypothesis adopted is that the EU lacks information about the costs of individual fishermen. In light of this imperfection, there are at least two reasons for considering an EU tax. First, it can be used to correct part of the market failure associated with fisheries. Second, it can be used to secure correct revelation of fishermen types in light of asymmetric information.

Bioeconomic Household Modelling For Agricultural Intensification, Gideon Kruseman

Gideon Kruseman

The study develops a bio-economic modelling framework that permits simultaneous assessment of the effects of technology change and policy measures on household welfare and agro-ecological sustainability indicators. The bio-economic modelling framework expands traditional farm household models to incorporate direct consumption utility functions, to allow for multiple objectives and to permit a meaningful interface with biophysical process models. The resulting model combines econometrically estimated equations in a mathematical programming framework. Model outcomes are analysed using metamodelling tecyhniques.

The bio-economic modelling framework is relevant for policy analysis related to resource degradation in developing countries. The model is applied to Cercle de Koutiala …

Domestic Demand For Petroleum In Opec Countries, Ujjayant N. Chakravorty, Fereidun Fesharaki, Shuoying Zhou

Ujjayant Chakravorty

The literature on OPEC energy policy has focused primarily on its production and export potential. The rapidly increasing domestic demand for petroleum products in OPEC countries has often been ignored. This study estimates domestic demand for petroleum products by the major OPEC economies and forecasts consumption trends under alternative assumptions regarding economic growth and price deregulation. It concludes that product demand is generally price and income inelastic and thus domestic consumption in OPEC will continue to grow rapidly, even if domestic prices are raised closer to world levels in the near future.

Dicko Prof.

Pr. Mamoudou H. DICKO, PhD

The objective of this study was the research of novel and inexpensive sources of polysaccharides degrading enzymes such as amylases and glucanases from local plants in order to justify their biotechnological applications. The isolation of two l3-amylases and an endo-1,3-ß-D-glucanase was reached using common protein purification methods such as buffer extraction, ammonium sulfate fractionation, ionexchange and gel filtration chromatographies. The methods used were simple and easily reproducible, suggesting the possibilfty of large-scale production. ln the crude extract of Curculigo pilosa tuber, only ß-amylase was detected as starch degrading enzyme and its activity was approximately 282 Uig of fresh material. The …

Amenities And Fringe Benefits: Omitted Variable Bias, Philip E. Graves, Robert L. Sexton, Michelle M. Arthur

Robert L Sexton

If labor is fairly mobile, as it is in the United States, one would expect that households would move from less desirable areas toward more desirable areas until all areas are equally desirable. The way that areas become equally desirable is through the impact of movers on wages and rents (and possibly "endogenous" disamenities, such as congestion or pollution). That is, as people move to desirable areas, they will increase the demand for land (raising rents) and increase the supply of labor (lowering wages); in equilibrium, the wage and rent "compensation" for the niceness of an area reveals, in dollar …

Measures Of Welfare Effects In Multiproduct Industries: The Case Of Multispecies Individual Quota Fisheries, Niels Vestergaard

Niels Vestergaard

A framework is developed to measure the welfare effects of individual quota reforms in multiproduct industries using the multimarket welfare measure techniques suggested by Just, Hueth, and Schmitz (1982) and the concept of virtual price in the production theory literature (Neary 1995; Squires and Kirkley 1996). Under joint in input production it shown that quasirent under a single quota can be measured by the producer surplus either in the output market for quota output or in the quota market. Under multiple quotas the welfare effects of quota policies can be measured in one of the quota markets using inverse derived …

Lessons Of A Drought, Ujjayant N. Chakravorty

Ujjayant Chakravorty

Water will become the most prized and precious commodity in the coming years. Internecine conflicts over the resource are already the order of the day and a global water crisis seems not too far away. But the water-guzzling US state of California is showing a way out of the problem - by allowing farmers to sell their share of water, it is pushing them to become efficient water users.

Endogenous Substitution Among Energy Resources And Global Warming, Ujjayant N. Chakravorty, James Roumasset, Kin-Ping Tse

Ujjayant Chakravorty

The theory of resource extraction has focused primarily on extraction when there is a single, homogeneous demand for the resource. In reality, however, we observe the simultaneous extraction of different resources such as oil, coal, and natural gas and multiple demands such as transportation, residential and commercial heating, and electricity generation. This paper develops a model with multiple resources and grades and multiple demands. The model is simulated with extraction cost, estimated reserves, and energy demand data for the world economy. It is shown that if historical rates of cost reduction in the production of solar energy are maintained, more …

Technology Adoption In The Presence Of An Exhaustible Resource: The Case Of Groundwater Extraction, Ujjayant N. Chakravorty, Farhed Shah, David Zilberman

Ujjayant Chakravorty

In this paper we integrate technology diffusion within Hotelling's exhaustible resource model. The modern technology is a conservation technology such as drip irrigation used with groundwater. Resource quality heterogeneity and rising water prices are responsible for the gradual adoption of the modern technology, and under reasonable conditions the diffusion curve is an S-shaped function of time. Without intervention, the diffusion process will be slower than is socially optimal, and optimal resource use tax will accelerate the diffusion of the conservation technology and slow down excessive resource depletion caused by market failure due to open access conditions.

Bæredygtig Udnyttelse Af Fornybare Ressourcer: Torskefiskeriet Ved Færøerne, Niels Vestergaard

Niels Vestergaard

The Faroe Islands cod fishery is analyzed for the period 1985-1992. It is shown that an approximately optimal and implementable fishery policy based on sustainability have increased the gross national income in the fishery by about 20%. This loss is due to an inoptimal organization of the fishery during that period combined with a very low cod stock at the end of 1992, which means reduced future catch possibilities. that the fishing capacity could have been reduced by about 1/3. The policy of sustainability is applied to the current situation in the fishery, and it is shown that the current …

Efficient Spatial Allocation Of Irrigation Water, Ujjayant N. Chakravorty, James Roumasset

Ujjayant Chakravorty

In the presence of conveyance losses, the efficient quantity of water applied falls with distance from the water source, but the amount of water "sent" (including conveyance losses) actually increases with distance from the source, except toward the tail end of the irrigation system. This implies that if marginal cost pricing were implemented, farmers at the middle and lower reaches of the system would have to pay more money for less water received. The model is illustrated and alternative financing schemes compared for an empirically derived demand function for irrigation water.

Competitive Oil Prices And Scarcity Rents When The Extraction Cost Function Is Convex, Ujjayant N. Chakravorty, James Roumasset

Ujjayant Chakravorty

The relationship between the time path of equilibrium prices and scarcity rents in the case of exhaustible resources depends on the nature of the extraction cost function. This paper examines the characteristics of the resource price path and scarcity rents when the extraction cost function is increasing and convex - a shape that seems to predominate in empirical work, especially in the case of oil. Scarcity rents eventually decline and the competitive price path inflects at the point where the scarcity rents stop rising. The theory is illustrated by using realistic cost and demand estimates from the oil industry.
