DETERMINANTS OF THE VALUE OF SITE-SPECIFIC INFORMATION (SSI) IN AGRICULTURE: A UNIFYING THEORY TO ANALYZE ITS RELATIVE IMPACTS AgEcon
Rejesus, Roderick M.; Nelson, Carl H..
This paper develops a theoretically consistent behavioral model of farmer decision-making that allows for analysis of the relative impacts of the determinants of SSI value. The model departs from previous literature by assuming that SSI reduces uncertainty, but not eliminate it. Results show that increasing the accuracy (or the "level of informativeness") of SSI, increasing initial wealth, improving management ability to reduce uncertainty in the posterior, and increasing the uncertainty in the prior, increases the value of SSI. Furthermore, mean input use is found to decrease, as SSI becomes more "informative." On the other hand, the value of SSI is found to be decreasing as relative risk aversion increases. These results have policy implications for...

Food Calorie Intake under Grain Price Uncertainty: Evidence from Rural Nepal AgEcon
Pan, Suwen; Fang, Cheng; Rejesus, Roderick M..
This study evaluates the effects of grain output price uncertainty on the farm income of rural households and, consequently, how this uncertainty influences caloric intake through changes in farm income. Using a rural household data set, augmented with output price uncertainty measures calculated from historical time-series data, we find that grain output price uncertainty tends to decrease crop production income of rural households. In addition, we find that higher crop income from production increases calorie intake of rural households. Taken together, these results suggests that output price uncertainty during the production process may tend to reduce caloric intake of rural Nepalese households since the price uncertainty negatively affects the crop...

Sources of Productivity Growth in Wheat: A Review of Recent Performance and Medium- to Long-Term Prospects AgEcon
Rejesus, Roderick M.; Heisey, Paul W.; Smale, Melinda.
Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years and is likely to continue to decline in the future. One potential source of yield growth in wheat during the medium to long term is improved efficiency of input use, rather than input intensification, through sustainable wheat production practices rather than pure input increases. Other large gains could be made with continuous adoption of newer and better modern varieties based on advances in wheat breeding. Wide crossing and biotechnology could improve the stability of wheat yields in the intermediate term; their long-term impact on...

Changing Pattern in U.S. Apparel Trade Post-2008: Implications for U.S. Cotton AgEcon
Mutuc, Maria Erlinda M.; Mohanty, Samarendu; Malaga, Jaime E.; Rejesus, Roderick M..
In 1995, the Agreement on Textiles and Clothing (ATC) provided for the calculated liberalization of the textiles and apparel sectors over a 10-year period ending in 2005, except for some safeguard measures ending on December 31, 2008. These safeguard measures allowed for import restrictions by the U.S. on certain categories of cotton apparel from China. Using a 57-equation, annual econometric, price equilibrium simulation model of the U.S. cotton and cotton apparel markets, results point to lower cotton apparel prices in the U.S. by as much as $ 0.25 per kilogram while cotton prices decline by less than $ 0.01 per kilogram once these safeguards expire. In the baseline scenario, quotas are removed in 2009-2015 except for the safeguards. In the...

Impacts of an Agricultural Development Program for Poor Coconut Producers in the Philippines: An Approach Using Panel Data and Propensity Score Matching Techniques AgEcon
Rodriguez, Divina Gracia P.; Rejesus, Roderick M.; Aragon, Corazono T..
Using panel data econometric techniques and propensity score matching procedures, this study evaluates the impact of the MAUNLAD agricultural development program - a program designed to help alleviate poverty in Philippine coconut-producing communities. Our results indicate that the program had a significant positive mean effect on the recipients' total net farm income. Moreover, the probability of being in poverty is shown to decrease when a poor coconut producer participates in the program. The program's emphasis on training, intercropping, and livestock integration, as well as the more participatory approach taken, contributed to the strong positive impact of the program.

Factors Affecting Farmers’ Utilization of Agricultural Risk Management Tools: The Case of Crop Insurance, Forward Contracting, and Spreading Sales AgEcon
Velandia, Margarita M.; Rejesus, Roderick M.; Knight, Thomas O.; Sherrick, Bruce J..
Factors affecting the adoption of crop insurance, forward contracting, and spreading sales are analyzed using multivariate and multinomial probit approaches that account for simultaneous adoption and/or correlation among the three risk management adoption decisions. Our empirical results suggest that the decision to adopt crop insurance, forward contracting, and/or spreading sales are correlated. Richer insights can be drawn from our multivariate and multinomial probit analysis than from separate, single-equation probit estimation that assumes independence of adoption decisions. Some factors significantly affecting the adoption of the risk management tools analyzed are proportion of owned acres, off-farm income, education, age, and level of business risks.

EX POST MORAL HAZARD IN CROP INSURANCE: COSTLY STATE VERIFICATION OR FALSIFICATION? AgEcon
Rejesus, Roderick M..
This article examines the extent to which actual crop insurance indemnification behavior conforms to the theoretical predictions of two ex post moral hazard models – costly state verification and costly state falsification. A nonparametric regression technique is used to estimate the crop insurance indemnification profile for non-irrigated cotton in Texas. The results suggest that indemnification behavior in crop insurance is more in line with the costly state falsification paradigm. Thus, crop insurers seem to indemnify based on the assumption that it is not easy to verify actual ex post loss magnitude and eliminate the asymmetric information held by the insured farmers.

Household Vegetable Demand in the Philippines: Is There an Urban-Rural Divide? AgEcon
Mutuc, Maria Erlinda M.; Pan, Suwen; Rejesus, Roderick M..
A three-step estimation method and a Nonlinear Quadratic Almost Ideal Demand System (NQAIDS) are used to assess the vegetable demand behavior of rural and urban households in the Philippines. The results show that most of the expenditure and own-price elasticities of the vegetables analyzed are near or larger than unitary in both rural and urban areas. For majority of the vegetable commodities, there are no significant differences in the expenditure, own-price, and cross-price elasticities of urban households relative to rural households. Only demand for cabbage and tomatoes in the urban areas tend to be statistically different compared to rural areas. The demand behavior information gleaned from the analysis provides important insights that could help...

Patterns of Collusion in the U.S. Crop Insurance Program: An Empirical Analysis AgEcon
Rejesus, Roderick M.; Little, Bertis B.; Lovell, Ashley C.; Cross, Mike H.; Shucking, Michael.
This article analyzes anomalous patterns of agent, adjuster, and producer claim outcomes and determines the most likely pattern of collusion that is suggestive of fraud, waste, and abuse in the federal crop insurance program. Log-linear analysis of Poisson-distributed counts of anomalous entities is used to examine potential patterns of collusion. The most likely pattern of collusion present in the crop insurance program is where agents, adjusters, and producers nonrecursively interact with each other to coordinate their behavior. However, if a priori an intermediary is known to initiate and coordinate the collusion, a pattern where the producer acts as the intermediary is the most likely pattern of collusion evidenced in the data. These results have...

Safety Nets or Trampolines? Federal Crop Insurance, Disaster Assistance, and the Farm Bill AgEcon
Goodwin, Barry K.; Rejesus, Roderick M..
We review the implications of the 2007 Farm Bill for the risk management dimensions of U.S. agriculture and policy. Legislative proposals suggest significant changes in risk management policy, including the introduction of state or national revenue insurance. We also pursue an empirical analysis of the interrelationships of crop insurance, disaster relief, and farm profitability. We find an inverse relationship between disaster assistance and insurance purchases. Our analysis also suggests that farmers that buy insurance and that receive disaster payments tend to have higher returns to farming.

Empirically Evaluating the Flexibility of the Johnson Family of Distributions: A Crop Insurance Application AgEcon
Lu, Yue; Ramirez, Octavio A.; Rejesus, Roderick M.; Knight, Thomas O.; Sherrick, Bruce J..
This article examines the flexibility of the Johnson system of distributions by assessing its per-formance in terms of modeling crop yields for the purpose of setting actuarially fair crop in-surance premiums. Using data from corn farms in Illinois coupled with Monte Carlo simula-tion procedures, we found that average crop insurance premiums computed on the basis of the Johnson system provide reasonably accurate estimates even when the data are normal or come from a non-normal distribution other than the Johnson system (i.e., a beta). These results sug-gest that there is potential for using the Johnson system to rate previously uninsured crops that do not have historical insurance performance data upon which to base premium calculations.

Economics of Management Zone Delineation in Cotton Precision Agriculture AgEcon
Velandia, Margarita M.; Rejesus, Roderick M.; Segarra, Eduardo; Bronson, Kevin.
This paper develops a management zone delineation procedure based on a spatial clustering approach and evaluates its economic impact for the case of Texas cotton production. The results show that there is potential economic value in using a spatial approach to management zone delineation, but its value critically depends on the cost of collecting soil test information needed to delineate those zones.

SHARE TENANCY, OWNERSHIP STRUCTURE, AND PREVENTED PLANTING CLAIMS IN CROP INSURANCE AgEcon
Rejesus, Roderick M.; Escalante, Cesar L.; Lovell, Ashley C..
A theoretical model based on opportunity cost and expected utility principles establishes linkages between the likelihood of prevented planting claims in crop insurance, existing share leasing arrangements and internal farm business structures. Results of probit estimation procedures indicate that simpler internal business structures and a more dominant farmer-tenant leasing position can increase the probability of submitting a prevented planting claim.

Farmland Control Decisions under Different Intertemporal Risk Behavioral Constructs AgEcon
Escalante, Cesar L.; Rejesus, Roderick M..
Simulation-optimization techniques are employed to analyze changes in farmland control arrangements as a result of using different constructs of intertemporal risk behavior. Risk behavior based on constant absolute risk aversion (CARA) and constant relative risk aversion (CRRA) mean-standard deviation functions are used to achieve this objective. Specfically, a multi-period programming framework for a representative grain farm is developed to explore farmland control decisions under these two behavioral assumptions. Our results suggest that the use of a CRRA behavioral construct in analyzing farmland control decisions produce predictions that are more consistent with observed farm behavior.

Can Crop Insurance Premiums be Reliably Estimated? AgEcon
Ramirez, Octavio A.; Carpio, Carlos E.; Rejesus, Roderick M..
The objective of this paper is to compare the accuracy of crop insurance rating methods based on historical liability and indemnity data (similar to the procedure currently used by the Risk Management Agency) and “yield distribution” approaches. Estimated rates are compared to “true” rates using empirically-grounded simulation procedures that take into account common data availability constraints. Simulation results suggest that farm and county level rate estimates using the “yield distribution” approach are significantly more accurate than those based on historical indemnity and liability records.

Factors Influencing Artisanal Fisherfolks' Level of Support for Fishery Regulations: An Approach Using Alternative Ordered Logit Models AgEcon
Garcia, Alexis Arthur B.; Rejesus, Roderick M.; Genio, Emmanuel L..
This article examines factors influencing fishers' decision to support fishery regulations in coastal communities in the Philippines. Using the partial proportional odds variant of the ordered logit model, we show that higher education levels, implementation of regulatory ordinances, and the effectiveness of law enforcement significantly affect the likelihood of supporting fishery regulations in coastal communities.

Preference for Risk Management Information Sources: Implications for Extension and Outreach Programming AgEcon
Rejesus, Roderick M.; Knight, Thomas O.; Jaramillo, Mauricio; Coble, Keith H.; Patrick, George F.; Baquet, Alan E..
This article examines farmers’ preferences for various risk management information sources. Our results suggest that information from risk management experts, in-depth materials studied on their own, and popular press outlets tend to be preferred and are ranked highly by producers. Using a regression model to investigate farmer/farm attributes that affect preference for a particular risk management information source, we find that younger farmers with college education, higher leverage, assets greater than $1 million, risk-loving attitudes, and who have used professional services (marketing consultants) tend to prefer information from risk management experts, the Internet, and marketing clubs/other producers. On the other hand, producers who prefer...
