A Note on the Reliability Tests of Estimates from ARMS Data AgEcon
Kim, C.S.; Hallahan, Charles B.; Lindamood, W.A.; Schaible, Glenn D.; Payne, James.
USDA uses the concept of "publish-ability" rather than statistical reliability of an estimate for quality validation of USDA estimates, which is solely based on the sample size and the coefficient of variation (CV). We demonstrate conceptually how the reliability of the sample mean can be tested by estimating the upper and lower bounds of the confidence interval for an unknown population mean using the CV. However, the reliability test for the sample mean can be made only under the normality assumption. USDA multiple-way Agricultural Resource Management Survey (ARMS) estimates are used to illustrate the relative measure of precision for sample-based estimators.

Agricultural Profits and Farm Household Wealth: A Farm-level Analysis Using Repeated Cross Sections AgEcon
Blank, Steven C.; Erickson, Kenneth W.; Nehring, Richard F.; Hallahan, Charles B..
This study examines the relationship between agricultural profits and farm household wealth across locations and farm sizes in U.S. agriculture. A multiperiod household model is used to develop hypotheses for testing. Results indicate that farmland has out-performed nonfarm investments over the past decade. Thus, households may want to keep their farmland to build wealth, even if it requires them to earn off-farm income. The analysis implies that decision will be made based on farm household wealth factors having little to do with agriculture.

Changes in Debt Patterns and Financial Structure of Farm Businesses: A Double Hurdle Approach AgEcon
Harris, James Michael; Dillard, John; Erickson, Kenneth W.; Hallahan, Charles B..
This paper uses a double hurdle model to help explain one aspect of the changing capital structure of U.S. production agriculture--the increase in the number of debt free farms. Our findings suggest that nonfinancial factors, such as operator age, region, risk aversion, and financial factors such as debt service ability and the cost of capital play significant roles in distinguishing borrowers from non borrowers.

Determinants of Farm Household Income Diversification in the United States: Evidence from Farm-Level Data AgEcon
Mishra, Ashok K.; Erickson, Kenneth W.; Harris, James Michael; Hallahan, Charles B.; Uematsu, Hiroki.
This study examines the determinants of income diversification of farm households in the United States. Farm households allocate their time between farm and off-farm activities to help stabilized household income (consumption). What characterizes those households who engage in off-farm activities? Is there any pattern over time? Using 1999, 2003 and 2007 farm-level data from the USDA’s Agricultural Resource Management Survey (ARMS), this study estimates intensity of off-farm income (or income diversification). The results show that older operators, full owners, and small farms have higher intensity of off-farm income in total household income. In contrast, dairy farms, vertically coordinated farms and farms located in the Southern and Pacific regions have...

ECONOMIC ANALYSIS OF THE CHANGING STRUCTURE OF THE U.S. FERTILIZER INDUSTRY AgEcon
Kim, C.S.; Taylor, Harold; Hallahan, Charles B.; Schaible, Glenn D..
This article evaluates structural changes in the U.S. nitrogen fertilizer industry by using a decomposed Negative Binomial Regression model. Results indicate that the U.S. nitrogen fertilizer industry can be characterized as an industry involving price leadership in oligopoly. Declining profit-margins might have forced fertilizer producers to consolidate and eliminate duplicate operations. The market concentration level is expected to intensify as the natural gas price rises.

Economic costs and payoffs of bilateral/regional trade agreements AgEcon
Vollrath, Thomas L.; Hallahan, Charles B..
The rapid increase in the number of bilateral and regional free-trade agreements since 1995 is a striking development. The proliferation of these agreements has raised questions among academicians and policymakers about whether they have, in fact, opened markets, created trade, promoted economic growth, and/or distorted trade. This study uses panel data from the 1975-2005 period and the gravity framework to identify the influence of bilateral/regional free-trade agreements on bilateral trade in merchandise, agriculture, and clothing sectors. A benchmark, Heckman sample-selection, and two generalized models, one of which accounts for reciprocal-free-trade-agreement phase-in effects, are used to gauge the impact on partner trade of mutual as well as...

Economics and Productivity of Organic versus Non-organic Dairy Farms in the United States AgEcon
Gillespie, Jeffrey M.; Nehring, Richard F.; Hallahan, Charles B.; Morrison Paul, Catherine J.; Sandretto, Carmen L..
Technical and scale efficiencies are estimated for organic and non-organic dairy farms in the United States using an input distance function approach. A multinomial logit analysis is used to categorize the farms by technology. Large conventional farms outperformed smaller farms in most technology / organic / non-organic categories. There was high variability in net returns among the organics so that they did not differ significantly from the large conventional farms. The largest conventional non-organic operations and conventional organic operations tended to have the higher technical efficiencies.

Forage Outsourcing in the Dairy Sector: The Extent of Use and Impact on Farm Profitability AgEcon
Gillespie, Jeffrey M.; Nehring, Richard F.; Sandretto, Carmen L.; Hallahan, Charles B..
The extent of forage purchasing behavior in milk production and its impact on profitability are analyzed using data from the 2000 and 2005 dairy versions of the Agricultural Resource Management Survey. Forage outsourcing is more common with hay than with silage and haylage, and is more prevalent in the western United States. Though silage and haylage outsourcing is found to impact profitability, the major profitability drivers appear to be farm size and efficiency. Evidence of significant forage contracting is found in the western United States.

Impact of GE Crop Adoption on Quality-Adjusted Herbicide Use in U.S. Corn Production AgEcon
Nehring, Richard F.; Martin, Andrew; Fernandez-Cornejo, Jorge; Hallahan, Charles B.; Vialou, Alexandre; Wechsler, Seth James; Grube, Arthur.
This paper presents findings on the use of HT corn and quality-adjusted herbicide use for 12 key corn producing states using a panel data set for 1986-2008. Our preliminary findings indicate an insignificant impact of HT corn on herbicide use, conditioning or accounting for HT corn with other important drivers of corn herbicide use: HT soy, corn output price, glyphoste price, nonherbicide glyponsate price, and percentage of continuous corn and low-till corn. However, we find a positive and significant impact of HT corn on herbicide use in selected states, using regional interaction terms. We use econometric techniques to avoid spurious regression results. Other preliminary runs indicated that the results hold when running the US and regional interactions...

MARKET POWER AND COST-EFFICIENCY EFFECTS OF THE MARKET CONCENTRATION IN THE U.S. NITROGEN FERTILIZER INDUSTRY AgEcon
Kim, C.S.; Hallahan, Charles B.; Taylor, Harold; Schluter, Gerald E..
This article examines the effects of increasing market concentration level in the U.S. nitrogen fertilizer industry. Results indicate that the costs of market power are greater than the benefits of market concentration, in terms of manufacturing cost efficiency. To provide a stable nitrogen fertilizer supply at a relatively low price, it may be necessary to control natural gas price and/or reduce new import barriers from Middle East and former member states of the Soviet Union, where low cost gas is produced as a byproduct. Keywords: Nitrogen fertilizer, oligopoly, economies of size, market power, cost-efficiency.

Off-farm Income and Investments in Farm Assets: A Double Hurdle Approach AgEcon
Harris, James Michael; Blank, Steven C.; Erickson, Kenneth W.; Hallahan, Charles B..
The farm household structure is a complex set of inter-relationships between and among a variety of internal and external factors involving consumption, investment, and income-earning activities. In this paper we use ARMS data to explore the contribution of off-farm income to the viability of the farm business. We focus on the link between off-farm income and farm investment and whether off-farm income drives on-farm investment. The results indicate the importance of farm characteristics such as type, size, and location on the probability of investment but lead us to reject the hypothesis that off farm income is driving farm investment. Further research will be needed to further unweave some of the complex relationships involved in the farm household...

Off-farm Income and Risky Investments: What Happens to Farm and Nonfarm Assets? AgEcon
Andersson, Hans; Ramaswami, Bharat; Moss, Charles B.; Erickson, Kenneth W.; Hallahan, Charles B.; Nehring, Richard F..
Off-farm work improves and reduces the riskiness of household income. Theoretical analyses reveal that the level and riskiness of off-farm income affect demand for farm/nonfarm investments. A two-limit Tobit model is estimated using ARMS data for 1996-2003. The impact on investment behaviour is evaluated.
