Are U.S. Corn And Soybeans Becoming More Drought Tolerant?, Tian Yu, Bruce A. Babcock Oct 2009

Are U.S. Corn And Soybeans Becoming More Drought Tolerant?, Tian Yu, Bruce A. Babcock

CARD Working Papers

An objective drought index that measures the dry and hot conditions adversely affecting crop yields is used in a regression analysis to test whether corn and soybeans have become more drought tolerant. Results indicate that corn yield losses from a drought of a given severity, whether measured in quantity terms or as a percentage of mean yield, have decreased over time. The null hypothesis that the absolute level of soybean yield losses due to drought has not changed cannot be rejected. But soybean yield losses in percentage terms have decreased over time. Because drought is the primary cause of yield ...

Does Local School Control Raise Student Outcomes? Evidence On The Roles Of School Autonomy And Parental Participation, Victoria Gunnarsson, Peter F. Orazem, Mario A. Sanchez, Aimee Verdisco Oct 2009

Does Local School Control Raise Student Outcomes? Evidence On The Roles Of School Autonomy And Parental Participation, Victoria Gunnarsson, Peter F. Orazem, Mario A. Sanchez, Aimee Verdisco

Economics Publications

As early as 1962, international agencies such as the United Nations and the World Bank were advising that the decentralization of public service delivery could serve as a development strategy. The strategy has become even more prominent over the past 15 years, particularly in education.1 Decentralization efforts in developed countries include various programs in Australia, Canada, New Zealand, Spain, the United Kingdom, and in at least 44 states in the United States. Among the developing countries, Burkina Faso, Brazil, Chile, Colombia, El Salvador, Honduras, India, and Nicaragua have introduced new programs aimed at devolving power to the local schools ...


Cooperatives: A Competitive Yardstick For Health Care, Mark A. Edelman, John R. Dunn Sep 2009

Cooperatives: A Competitive Yardstick For Health Care, Mark A. Edelman, John R. Dunn

Economics Working Papers (2002–2016)

As the national debate over health care reform continues, consideration is increasingly being given to the use of consumer-focused health care cooperatives as a key strategy for providing access to affordable health care and insurance for the millions of consumers and small businesses not presently able to afford or obtain adequate health care. Historically in many other sectors, the cooperative form of business has been successfully adapted by farmers, consumers, businesses, and public bodies as an effective strategy for attaining scale, lowering costs, improving incomes, providing services, and creating a better functioning marketplace. Reasons for forming cooperatives and analysis of ...


Hazards Of Basing An Estate Plan On Successive Life Estates, Neil E. Harl Sep 2009

Hazards Of Basing An Estate Plan On Successive Life Estates, Neil E. Harl

Agricultural Law Digest

Recent reviews of two fact situations, hundreds of miles apart and both the products of planning a half century or more ago, illustrate the hazards of using a deceptively simple estate plan – basing the plan on successive life estates.1 The strategy often involves unexpected federal estate tax consequences,2 federal gift tax problems,3 income tax basis complications4 and assorted problems relating to like-kind exchanges, involuntary conversions and easements, to mention just a few of the more likely events occurring during the term of the life estates. Although often viewed as more complex (and costly to set up ...

Human Development and Family Studies Publications

Background: Schools are the most frequent target for intervention programs aimed at preventing child obesity; however, the overall effectiveness of these programs has been limited. It has therefore been recommended that interventions target multiple ecological levels (community, family, school and individual) to have greater success in changing risk behaviors for obesity. This study examined the immediate and short-term, sustained effects of the Switch program, which targeted three behaviors (decreasing children's screen time, increasing fruit and vegetable consumption, and increasing physical activity) at three ecological levels (the family, school, and community).

Methods: Participants were 1,323 children and their parents ...


More On Related-Party Like-Kind Exchanges, Neil E. Harl Sep 2009

More On Related-Party Like-Kind Exchanges, Neil E. Harl

Agricultural Law Digest

Although like-kind exchanges have been almost routine for decades for trades involving machinery, equipment and business vehicles,1 the use of like-exchanges for real estate has become much more widespread in recent years.2 Until 1989, there were no limitations imposed on related-party like-kind exchanges. The 1989 amendment imposing limits on related party like-kind exchanges3 was motivated by concern overthe tax avoidance potential of transactions in which related parties enter into like-kind exchanges involving low-basis property (which the owner contemplates selling) for high basis property with the new owner of the high basis property selling the property received at ...

The Impact Of Biofuels Policy On Agribusiness Stock Prices, Fatma Sine Tepe, Xiaodong Du, David A. Hennessy Sep 2009

The Impact Of Biofuels Policy On Agribusiness Stock Prices, Fatma Sine Tepe, Xiaodong Du, David A. Hennessy

CARD Working Papers

Corn markets are important for many industries, including the seed, fertilizer, meat production/processing and agricultural machinery sectors, all of which are highly concentrated. Oligopoly theory suggests that corn input and field equipment suppliers likely benefit from policies that support corn markets, such as U.S. biofuels policy, while meat companies are likely adversely affected. Employing a linear two-factor (S&P 500 and corn prices) equilibrium asset pricing model, this study investigates the impact of biofuels policy on U.S. agribusiness and food processing firm stock prices. Conditional heteroskedasticity in stock returns is accounted for using a GARCH(1,1 ...


Dynamics Of Biofuel Stock Prices: A Bayesian Approach, Xiaodong Du, Dermot J. Hayes, Cindy L. Yu Sep 2009

Dynamics Of Biofuel Stock Prices: A Bayesian Approach, Xiaodong Du, Dermot J. Hayes, Cindy L. Yu

CARD Working Papers

We use Bayesian Markov Chain Monte Carlo methods to investigate the linkage between the volatility of ethanol security prices and the uncertainty surrounding the profitability of ethanol production and the price variations of non-ethanol energy securities. The joint evolution of return and volatility is modeled as a stochastic process that incorporates jumps in both return and volatility. While a strong and significant correlation is found between the volatility of ethanol securities and profit uncertainty from June 2005 to July 2008, the dynamic pattern of ethanol stock volatility is strikingly similar to that of the S&P 500 energy sector index ...


Impacts Of Agricultural Expansion On Surface Runoff: A Case Study Of A River Basin In The Brazilian Legal Amazon, E. E. Maeda, A. R. Formaggio, Y. E. Shimabukuro, Amy L. Kaleita Sep 2009

Impacts Of Agricultural Expansion On Surface Runoff: A Case Study Of A River Basin In The Brazilian Legal Amazon, E. E. Maeda, A. R. Formaggio, Y. E. Shimabukuro, Amy L. Kaleita

Agricultural and Biosystems Engineering Publications

This work presents an analysis of the Land Use and Land Cover (LULC) changes of a region in the Brazilian Legal Amazon, and an evaluation of their impacts on the surface runoff regime. This case study took place at the Suiá-Miçu River basin, located in the northeast region of Mato Grosso State. LULC maps were produced for the years 1973, 1984 and 2005 using remote sensing data. After analyzing the agricultural expansion in the study area, the Automated Geospatial Watershed Assessment Tool (AGWA) was applied in performing the surface runoff modeling for each of the analyzed years using the SCS ...


Crop Residues: The Rest Of The Story, Douglas L. Karlen, Rattan Lal, Ronald F. Follett, John M. Kimble, Jerry L. Hatfield, John A. Miranowski, Cynthia A. Cambardella, Andrew Manale, Robert P. Anex, Charles W. Rice Sep 2009

Crop Residues: The Rest Of The Story, Douglas L. Karlen, Rattan Lal, Ronald F. Follett, John M. Kimble, Jerry L. Hatfield, John A. Miranowski, Cynthia A. Cambardella, Andrew Manale, Robert P. Anex, Charles W. Rice

Economics Publications

Synopsis In the February 15, 2009 issue of ES&T Strand and Benford argued that oceanic deposition of agricultural crop residues was a viable option for net carbon sequestration (43 [4], 1000−1007). In reviewing the calculations and bringing their experience to bear, Karlen et al. argue in this Viewpoint that crop residue oceanic permanent sequestration (CROPS) as envisioned by Strand and Benford will not work. They further propose alternative possibilities in agricultural methods to achieve a net decrease of CO2 emissions.


Bounding The Effects Of Food Insecurity On Children’S Health Outcomes, Craig Gundersen, Brent Kreider Sep 2009

Bounding The Effects Of Food Insecurity On Children’S Health Outcomes, Craig Gundersen, Brent Kreider

Economics Publications

Previous research has estimated that food insecure children are more likely to suffer from a wide array of negative health outcomes than food secure children, leading many to claim that alleviating food insecurity would lead to better health outcomes. Identifying the causal impacts is problematic, however, given endogenous selection into food security status and potential mismeasurement of true food security status. Using recently developed nonparametric bounding methods and data from the 2001-2006 National Health and Nutritional Examination Survey (NHANES), we assess what can be identified about the effects of food insecurity on child health outcomes in the presence of nonrandom ...


Technology And Innovation In World Agriculture: Prospects For 2010-2019, Wallace E. Huffman Aug 2009

Technology And Innovation In World Agriculture: Prospects For 2010-2019, Wallace E. Huffman

Economics Working Papers (2002–2016)

The objective of this paper is to assess prospects for increasing agricultural productivity through advances in technology and innovation in farming techniques for developed and selective developing and transition countries over 2010-2019. Over this period of time, the net impact of climate change is expected to be small, perhaps positive on cereal yields. However, environmental concerns (carbon dioxide release from bringing new lands into crop production and erosion on marginal lands brought into crop production, additional agricultural chemicals applied, and less biodiversity) may grow if meeting future demand for food, feed, fiber and bio-fuels require the conversion of forests and ...


Firm Entry, Firm Exit, And Urban-Biased Growth, Li Yu, Robert W. Jolly, Peter F. Orazem Aug 2009

Firm Entry, Firm Exit, And Urban-Biased Growth, Li Yu, Robert W. Jolly, Peter F. Orazem

Economics Working Papers (2002–2016)

We introduce a taxonomy that classifies industries using three criteria: net growth in the number of firms; the interrelationship between firm entry and firm exit; and the degree of urban-bias in industry growth. We show that in 9 of 15 two-digit NAICS industries investigated, there is evidence of urban bias consistent with a comparative advantage to starting a business in urban markets. The urban advantage is due primarily to faster firm entry rates. Urban and rural firms have similar firm exit rates, consistent with a presumption that there are equal expected profit rates conditional on entry across markets. Urban areas ...


A More Formal Disaster Relief Program, Neil E. Harl Aug 2009

A More Formal Disaster Relief Program, Neil E. Harl

Agricultural Law Digest

Until 2008, with some exceptions which featured a more general scope,1 disaster relief tended to be enacted for a specific term and for a specific disaster.2 As an example, the $100 deductible was suspended for losses on or after August 25, 2005, attributable to Hurricane Katrina.3 However, in the Emergency Economic Stabilization Act of 2008,4 the Congress created what some have termed a national disaster relief program. Additional legislation may be needed to create a complete fabric of relief provisions, particularly in light of the fact that many of the 2008 enactments have a limited life ...

Unit Vs. Ad Valorem Taxes In Multi-Product Cournot Oligopoly, Harvey E. Lapan, David A. Hennessy Aug 2009

Unit Vs. Ad Valorem Taxes In Multi-Product Cournot Oligopoly, Harvey E. Lapan, David A. Hennessy

Economics Working Papers (2002–2016)

The welfare dominance of ad valorem taxes over unit taxes in a single-market Cournot oligopoly is well-known. This article extends the analysis to multi-market oligopoly. Provided all ad valorem taxes are positive, unit costs are constant, firms are active in all considered markets, and a representative consumer has convex preferences, it is shown that ad valorem taxes dominate in multi-product equilibrium. We discuss the role of unit cost covariances across multi-product firms in determining the extent of cost efficiencies arising under ad valorem taxation. The issue of merger under oligopoly is also considered. Conditions are identified under which a merger ...


Fishing Behavior Across Space And Time, Luc Pierre Veyssiere, Quinn Weninger Aug 2009

Fishing Behavior Across Space And Time, Luc Pierre Veyssiere, Quinn Weninger

Economics Working Papers (2002–2016)

Models of fishing behavior rarely incorporate the complexities of marine ecosystems, multiple-stock harvest technologies, and regulations present in real world marine fisheries. We introduce a structural model of a multi-species, weak-output-disposability harvest technology. A latent target-cost-minimizing share vector is estimated to link the technology to a spatially and temporally heterogeneous fish stock. Data from the Gulf of Mexico reef fish fishery is used to estimate the model. The results provide a robust characterization of harvest and discard behavior across space and time. Our approach considerably improves methods used to study fishing behavior and evaluate alternative fisheries management policies.

International Extension Curriculum: Strengthening Extension's Capacity For International Engagement—Module 6: Exploring Cultural Perspective Of Families, Kimberly A. Greder, Beth Fleming, Tom Quinn

Human Development and Family Studies Extension and Outreach Publications

Families build the foundation of communities. As the demographic profiles of families in communities change, communities change. In order to design and deliver extension programs and services to effectively meet the needs of communities, it is important to understand the needs and wants of those who live there. This module can provide professional development to extension staff. However, activities in this module can also be used in extension programming to assist others in learning about the role of culture in families, how individuals can design and deliver programs and services.


The 2007/08 Iowa Grain And Biofuel Flow Study: A Survey Report, Tun-Hsiang (Edward) Yu, Chad E. Hart Aug 2009

The 2007/08 Iowa Grain And Biofuel Flow Study: A Survey Report, Tun-Hsiang (Edward) Yu, Chad E. Hart

CARD Staff Reports

Driven by the expanding production of biofuels, the linkage between the agricultural and energy markets is evolving, and that has changed the market for agricultural commodities dramatically. These developments in agricultural markets consequently shifted the distribution of domestic grains and feeds and the utilization of shipping modes for these agricultural products. As the leading producer of corn, soybeans, and biofuels, Iowa is at the forefront of this shift. Because of the importance of maintaining an adequate state transportation system to accommodate the evolving patterns of grain and biofuel flows, it is important to have current information about grain flows from ...


When Does Retrieval Induce Forgetting And When Does It Induce Facilitation? Implications For Retrieval Inhibition, Testing Effect, And Text Processing, Jason C.K. Chan Aug 2009

When Does Retrieval Induce Forgetting And When Does It Induce Facilitation? Implications For Retrieval Inhibition, Testing Effect, And Text Processing, Jason C.K. Chan

Psychology Publications

Retrieval practice can enhance long-term retention of the tested material (the testing effect), but it can also impair later recall of the nontested material – a phenomenon known as retrieval-induced forgetting (Anderson, M. C., Bjork, R. A., & Bjork, E. L. (1994). Remembering can cause forgetting: retrieval dynamics in long-term memory. Journal of Experimental Psychology: Learning, Memory, and Cognition, 20(5), 1063–1087). Recent research, however, has shown that retrieval practice can sometimes improve later recall of the nontested material – a phenomenon termed retrieval-induced facilitation (Chan, J. C. K., McDermott, K. B., & Roediger, H. L. (2006). Retrieval-induced facilitation: initially nontested material can ...

Economics Publications

We examine four scenarios for the evolution of the biofuel sector using a partial equilibrium model of the world agricultural sector. The model includes the new Renewable Fuels Standard in the 2007 energy act, the 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. Of the remaining two scenarios, one considers a pure market ...


The Tax Court And The U.S. Court Of Federal Claims Agree: Members Of Llcs And Llps Are Not To Be Treated As Limited Partners, Neil E. Harl Jul 2009

The Tax Court And The U.S. Court Of Federal Claims Agree: Members Of Llcs And Llps Are Not To Be Treated As Limited Partners, Neil E. Harl

Agricultural Law Digest

In a decision in late June, 2009, the United States Tax Court1 held that ownership interests in a limited liability company (LLC) or limited liability partnership (LLP) should not be treated as limited partners in a limited partnership.2 About a month later, the U.S. Court of Federal Claims decided a case3 that went a notch beyond the holding in the earlier Tax Court case. That provides major support for the view that the statute which states “. . . [e]xcept as provided in regulations, no interest in a limited partnership as a limited partner shall be treated as ...
