Advocated across the international community for more than 15 years, the Extractive Industries Transparency Initiative (EITI) is now widely recognised as a hallmark anti-corruption scheme in the extractive sector. This study presents an assessment of the relationship between EITI membership and countries’ progress in tackling corruption. It provides the first study that looks at this issue using a ‘state-of-the-art’ indicator called the Bayesian Corruption Indicator. It also introduces an innovative estimation strategy combining entropy balancing with a difference-in-difference framework to address the baseline inequalities that exist between member and non-member countries. Contrary to the findings of many leading studies, this analysis finds corruption scores have improved significantly among EITI member countries. In particular, the evidence is strongest when we examine a sub-group of EITI members designated fully compliant with the initiative's transparency standards.

In response to the CITES ban on trade in elephant ivory, mammoth ivory began to be produced in post-Soviet Russia. We investigate how this substitute to elephant ivory has affected the poaching of elephants. We argue that the early success of the 1989 ivory ban at increasing the African elephant population was driven in part by increasing supply of mammoth ivory. The more recent increases in poaching appear to be driven by increasing demand and falling African institutional quality. We find that absent the 80 tonnes of Russian mammoth ivory exports per annum 2010–2012, elephant ivory prices would have doubled from their $ 100 per kilogram level and that the current poaching level of 34,000 elephants per year may have increased by as many as 55,000 elephants per year on a population of roughly half a million animals.

Farmland reallocation between farmers through rental transactions is critical for improving Japanese rice productivity. This study examined effects of socio-institutional and emotional factors as well as economic factors on rental transactions. A stochastic choice model was applied to contingent valuation data by considering regional heteroscedasticity. Empirical results showed (1) existence of economic inefficiencies, 3% loss of economic surplus due to socio-institutional restriction, which is probably reflected in transaction costs; (2) a 15% reduction in surplus due to emotional reluctance of farmers; and (3) strong influences of rice price, wages, and geographical location on the rental rate and agreement level.

Because of the decline of the Ogallala Aquifer, water districts, regional water managers, and state water officers are becoming increasingly interested in conservation policies. This study evaluates both short-term and long-term water rights buyout policies. This research develops dynamic production functions for the major crops in the Texas Panhandle. The production functions are incorporated into optimal temporal allocation models that project annual producer behavior, crop choices, water use, and aquifer declines over 60 years. Results suggest that long-term buyouts may be more economically efficient than short-term buyouts.

Three economic opportunities are presented for rural areas in this invitedpaper session: self-employment, investments in broadband infrastructure, andagritourism. Self-employment has shown growth in rural regions at theexpense of wage and salary employment in the long-term. Productionagriculture interests by themselves are unlikely to provide sufficientfunding to expand infrastructure for broadband in rural areas. Agritourismapproaches appear to be very wide ranging with many educational demandsneeding to be met to maximize its diversification possibilities. Researchand extension faculty should be careful to focus on explaining the tradeoffsof these opportunities so that rural stakeholders do not fall victim to thelatest academic economic development fad.

We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where the biofuel sector expands with higher energy price, raising the prices of most agricultural commodities through demand side adjustment channels for primary feedstocks and supply side adjustment channels for substitute crops and livestock. On the other hand, the biofuel sector shrinks coupled with opposite impacts on agricultural commodities with the removal of all support including the tax credit. Also, we find that given distribution bottlenecks, cellulosic ethanol crowds marketing channels resulting in a corn-based ethanol price that is discounted. The blenders' credit and consumption mandates provide a price floor for ethanol and for corn. Finally, the tight linkage between the energy and agricultural sectors resulting from the expanding biofuel sector may raise the possibility of spillover effects of OPEC's market power on the agricultural sector.

This research analyzes two groundwater conservation policies in the Kansas High Plains located within the Ogallala aquifer: 1) cost-share assistance to increase irrigation efficiency; and 2) incentive payments to convert irrigated crop production to dryland crop production. To compare the cost-effectiveness of these two policies, a dynamic model simulated a representative irrigator's optimal technology choice, crop selection, and irrigation water use over time. The results suggest that the overall water-saving effectiveness can be improved when different policy tools are considered under different conditions. High prevailing crop prices greatly reduce irrigators' incentive to give up irrigation and therefore cause low enrollment and ineffectiveness of the incentive payment program. In areas with low aquifer-saturated thickness, the incentive payment program is more effective, whereas in areas with relatively higher water availability, the cost-share program could be a better choice.

The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities.

Agriculture in the Texas High Plains depends entirely on the Ogallala Aquifer. Texas enacted water conservation legislation to address declining reserves in the aquifer. We developed an integrated regional water policy model that links a hydrology model with an economic optimization model to estimate policy impacts with respect to economic cost and water conservation. Testing the effectiveness of two policies, a groundwater extraction tax and extraction quotas, we observe that neither significantly inhibits groundwater use. Although both policies conserve similar amounts of groundwater, the regional cost of the tax policy to agriculture is more than the quota policy.

Since the Internet's inception its impact has been felt across the UnitedStates, but the distribution and adoption of the Internet has notnecessarily been uniform geographically. As more consumers and businessesrely on the Internet to access information, the data transmissionrequirements have also increased. Consequently, access to broadband hasbecome increasingly more important since dial-up cannot realistically handlethe increased requirements. The use of broadband in agriculture can providebetter access to price, weather, and management information while alsoopening new markets. However, many rural communities lag behind urban areasin broadband access and adoption rates. This study evaluates, through theuse of a producer survey, the level of broadband Internet use, motivationsfor its use, degree of access to broadband, and willingness-to-pay (WTP) tofund broadband infrastructure investments. Results from the producer surveysuggested farmers utilize the Internet primarily for accessing weatherreports, e-mail, market reports, and agricultural news. Notably, thesurvey's WTP questions allowed for the use of an interval regression tocalculate producer WTP for varying demographics. The results suggested thatproducers who were younger, farmed larger farms, and those who currently usethe Internet but do not have broadband access were WTP more in propertytaxes to support broadband infrastructure investments than those of adiffering demographic. Because WTP levels varied drastically depending onthe underlying demographics, it becomes difficult to pinpoint a WTP levelfor a one-time payment in property taxes that would be acceptable from apolicy standpoint.

This paper provides a brief overview of policy intervention mechanisms affecting the preservation of the historic environment in Britain. This covers half a million “listed buildings” in England alone. Within this policy framework, the paper then discusses stated preference valuation exercises on the built environment and the results of a long – term exercise comparing returns of listed and unlisted office properties in the UK since 1980.
