An analysis of irrigated agricultural outcomes under the prior appropriation doctrine: hypotheses and applications

This article measures irrigated agricultural outcomes under the prior appropriation doctrine by developing a model of farmers’ land allocations in response to water supply change. The modelling approach considers the institutional factors of water rights and permits the inclusive determination of water and land allocations. We utilize farm-level data of irrigated agriculture in Water District #1 in Idaho to examine the predictions from our theoretical model. The water rights priority date is consolidated at the farm level and used to differentiate farmers’ responses. We test a set of hypotheses that relate to water supply and crop revenue. Our results suggest that the water rights priority has a profound impact on agricultural outcomes, indicating strong institutional effects and weak influence of market-based approaches. Farmers respond to both long-term and seasonal water supply change and variation, and they respond to seasonal water supply forecasts in varied ways depending on their water rights portfolios, thus signalling a disproportionate distribution of potential impacts of water supply change.     

Dynamics of fine wine and asset prices: evidence from short- and long-run co-movements

This article examines short- and long-term price linkages among the majority of fine wine and equity markets over the period of 2003 to 2012. We do not consider the price index (LIV-EX 100 or 500), as is typically undertaken in previous studies, but rather examine the auction price series of the world’s most traded wine-vintage pairs (5 Bordeaux first growth, 8 Bordeaux second growth, 5 Burgundy, 3 Rhone, 4 Italian, 5 Californian, 1 Australian and 1 Portuguese). A global equity index is also included using the Morgan Stanley Capital International World. Cointegration procedures, the Granger non-causality test, and ECM are used to analyse short- and long-run relationships among these markets. The results indicate a strong effect of financial markets on wine prices and short-term causality for certain wines. Moreover, the findings indicate short-run causality between the wines themselves, revealing a leader (exogenous) or follower (endogenous) status of certain fine wines in price dynamics, and also long-run causality for endogenous wines. This approach is relevant to portfolio diversification strategies and allows price movements to be anticipated more accurately than using an index approach.     

Downtown parking meter demand in a border metropolitan economy

Prior research establishes that the price of parking in the city centre often impacts the decision to travel downtown and the mode of transportation utilized. Other factors that influence the decision to drive and park downtown have received less attention. This study uses time series data to analyse the demand for metered parking spaces in El Paso, Texas, USA. In addition to meter rates, the determinants of demand include personal income, gasoline prices and the price of a substitute good, parking garage spaces. Because international bridges connect downtown El Paso to neighbouring Ciudad Juárez, Chihuahua, Mexico, the impacts of trans-boundary traffic flows, bridge tolls and other cross-border economic variables are also included as potential determinants of metered parking demand. Results indicate that parking meter rates, other transportation-related costs, and economic conditions in both countries affect meter use.     

Evaluating the impact of the American Recovery and Reinvestment Act’s BTOP on broadband adoption

The American Recovery and Reinvestment Act’s Broadband Technology Opportunities Program (BTOP) spent $4.7 billion during 2009–2013 to, inter alia, increase broadband adoption in underserved communities. We characterize the BTOP grants and examine the impact of the awards on broadband adoption. Econometric specifications controlling for award endogeneity related to observed and unobserved county-level factors find that spending is apparently associated with increased broadband adoption. Further investigation, however, reveals that the impacts of spending are nonlinear and even nonmonotonic over the range of county-level BTOP spending in the data. Controlling for trends to reduce the potential for spurious correlation between spending and outcomes removes most of the significance of the results. We conclude with three lessons for policymakers derived from the uncertain outcomes of BTOP spending found in our exploration.     

Hedging effectiveness of fertilizer swaps

The fertilizer swaps market is a potential tool to protect against fertilizer price risk. The swaps evaluated here are cash settled using The Fertilizer Index. Hedge ratios and hedging effectiveness are calculated for urea and DAP diammonium phosphate (DAP)) swaps. Urea and DAP swaps perform poorly as a hedging tool over a one-week horizon. As the hedging horizon increases, the hedging effectiveness of swaps improves. The swaps are more effective in mitigating risk across ocean freight routes than across inland routes. The limited hedging effectiveness is due to high spatial basis risk in fertilizer markets.     

Technology Strategies For Economic Development In A Fast Changing Global Economy

East Asian development experience provides the basis for understanding which are the essential elements of effective technology strategy and policy, those that are required for the efficacious development of countries that have not yet embarked on a path of sustained modernization. Globalization has had a profound impact on development, enabling countries that could exploit its propelling forces to pursue a potent strategy of export-led economic and technological development. The policies needed to sustain this strategy are those required to foster institutions that permit effective commerce among economic agents, those necessary to generate the rapid accumulation of human and physical capital, and those essential to ensure that resources are allocated in accord with the economy's dynamic comparative advantage. Of crucial importance among the latter are effectively implemented policies of selective intervention designed to develop infant industries and to foster their fast-paced achievement of international competitiveness through rapid attainment of the requisite technological capabilities.     

Women,Ecology and Economics,edited by Ellie Perkins

This paper finds that black women earn 7 percent less than similarly skilled white women because of their race. Even within the same occupational category, black women earn 3 percent less than similarly qualified white women. Black women receive lower pay primarily due to occupational segregation and because they are rewarded with lower earnings than white women for equivalent levels of education and other human capital characteristics.     

Economic importance and statistical significance: Guidelines for communicating empirical research

Abstract

A critical objective for many empirical studies is a thorough evaluation of both substantive importance and statistical significance. Feminist economists have critiqued neoclassical economics studies for an excessive focus on statistical machinery at the expense of substantive issues. Drawing from the ongoing debate about the rhetoric of economic inquiry and significance tests, this paper examines approaches for presenting empirical results effectively to ensure that the analysis is accurate, meaningful, and relevant for the conceptual and empirical context. To that end, it demonstrates several measurement issues that affect the interpretation of economic significance and are commonly overlooked in empirical studies. This paper provides guidelines for clearly communicating two distinct aspects of “significance” in empirical research, using prose, tables, and charts based on OLS, logit, and probit regression results. These guidelines are illustrated with samples of ineffective writing annotated to show weaknesses, followed by concrete examples and explanations of improved presentation.     

The Roles of Independent Research and Technology Organizations in the United Kingdom's Technology Transfer Mechanism to SMEs

Independent Research and Technology Organizations (RTOs) provide an increasing proportion of the UK's technology services requirements. RTOs, often former state research establishments spun out into the private sector, provide technology consulting and networking services to specific sectors or for generic technologies; some are membership-based organizations while others work for contract clients. In this paper we explore the roles and services provided by RTOs, together with the measures being taken to assist small firms that, for many RTOs, form a new and challenging market. The diversity of services and approaches to SMEs are related, in part, to the different origins of RTOs. The research indicates three forms of technology services market failure that suggest a need for ongoing external support for the market's mechanism.
