Homo Agricola considered as Homo Economicus and Homo Politicus

Zawojska, Aldona.

The paper is of descriptive character and is based on literature review. It reviews the concept of homo economicus and homo politicus in the history of economic thought and tries to discover their characteristics in homo agricola. As demonstrated, one component of homo agricola can be of economic and another one of political nature. Those components can be separated or can be together. Agricultural economists, however, in their sophisticated mathematical models seem to reduce farmers’ behaviour to economic behaviour or rather to self-interested homo economicus. Institutional economics, social economics and socio-economics are closer to actual human nature, than homo economicus. The further research challenge before agricultural academia is to develop the...

The information presented in this report represents data collected from farming and ranching operations in the southern two tiers of counties in Nebraska. This study was based on a random sample of 151 southern Nebraska farms that have annually-planted crop acreage. Information was obtained for the 1997 crop year. This data set is referred to as the MSU/UNL survey data. From the MSU/UNL survey data, the average size of the farming operations in the survey, in 1997, was 1,316 acres. Of these, 856 acres were planted to annual crops, and the remaining 460 acres included 61 acres in fallow, 29 acres in hay, 287 acres in range and pasture, 28 acres in CRP, and 55 acres in other uses. Operation size was largest in the west, due mostly to a large number of range...

Kirwan, Barrett E.; Martens, Andrea.

Exogenous, unobserved factors often confound the effects of alliance networks. More capable farmers might be less likely to exit and more likely to have a large number of alliances. In this case the negative correlation between alliance network size and exit likelihood is due to the unobserved confounder--farmer ability--not the effect of network size on exit likelihood. Recognizing the endogeneity of alliance network size when determining a farm’s survival likelihood, we employ an empirical model that accounts for the bias caused by unobserved effects. We account for time-invariant unobserved effects with individual fixed effects. We control for county-level confounding factors with a time-varying county effect. Finally, we address unobserved,...

Rahman, Sanzidur.

This paper applies the sequential Malmquist index to calculate multi lateral, multi-factor productivity (MFP) indices for agriculture in 16 regions of Bangladesh from 1964 to 1992 and examines convergence among regions. Productivity grew at an average rate of 2.2% per annum, led by regions with high level of Green Revolution technology diffusion. The growth mainly occurred due to technological progress estimated at 2.1% per year. Overall technical efficiency declined slightly at 0.1% per year due to falling technical efficiency in most of the regions in later years. Both cross-section and time series tests confirmed that divergence among regions disappeared and agricultural productivity reached convergence in the long run.

The primary objective of this paper is to evaluate alternative control strategies for a number of simulated outbreaks of Foot-and-Mouth Disease (FMD) in four agriculturally diverse Irish regions, examining for the first time, the potential role of emergency vaccination in the country. The recent EU Directive (2003/85/EC) on FMD control permits the use of emergency vaccination as part of an FMD control strategy. While the slaughter of infected animals and dangerous contacts (susceptible animals on epidemiologically linked holdings) remains the principal tool for tackling an outbreak, the potential use of vaccination as an adjunct to the basic culling policy is now being considered. Using an integrated approach, combining epidemiological and economic...

Qaim, Matin; Stein, Alexander J.; Meenakshi, J.V..

Micronutrient malnutrition affects billions of people world-wide, causing serious health problems. Different micronutrient interventions are currently being used, but their overall coverage is relatively limited. Biofortification that is, breeding staple food crops for higher micronutrient contents has been proposed as a new agriculture-based approach. Yet, as biofortified crops are still under development, relatively little is known about their economic impacts and wider ramifications. In this article, the main factors that will influence their future success are discussed, and a methodology for economic impact assessment is presented, combining agricultural, nutrition, and health aspects. Ex ante studies from India and other developing countries...

A Coasian Approach to Efficient Water Allocation of a Transboundary River

Willis, David B.; Baker, Justin Scott.

The United States and Mexico recently resolved a decade-old water dispute that required Mexico to repay the accumulated water debt within one year. A Coasian analysis estimates the social welfare gains attainable to each country under an alternative debt repayment scheme that allows repayment over a longer time horizon and in a combination of dollars and water, instead of solely in water. Assuming average water supply conditions, under the agreed 1-year repayment contract, U.S. compensation value is 534% greater and Mexico’s compensation cost is 60% less relative to when compensation is paid exclusively in water.

Regional Wholesale Price Relationships in the Presence of Counter-Seasonal Imports

Raper, Kellie Curry; Thornsbury, Suzanne; Aguilar, Cristobal.

Counter-seasonal imports of fresh produce facilitate year-round availability in the U.S. and may impact the seasonal structure of market price relationships. Vector autoregression analysis is used to determine the nature and extent of spatial price relationships among four geographically distinct regions in the U.S. fresh peach wholesale market. We evaluate differences in regional spatial price relationships and find statistical evidence that price relationships among regions are different in periods dominated by regional domestic supplies imports compared with periods when counter-seasonal imports dominate the market.

JOINT ADOPTION OF MULTIPLE TECHNOLOGIES: A DUAL, LATENT DEMAND APPROACH

Lichtenberg, Erik; Strand, Ivar E., Jr..

Latent demand models can be used to overcome computational difficulties that frequently hamper empirical evaluation of relatedness in the adoption of multiple technologies. This paper develops and applies such an approach to a case involving agricultural soil and water conservation. The results indicate both complementarity and substitution. Own-price elasticities of demand for all technologies and cross-price elasticities of demand for related technologies are substantial. The results are used to derive implications for the design and implementation of cost sharing programs, which have been one of the primary policies used to address nonpoint source agricultural water pollution problems.

Epanchin-Niell, Rebecca S.; Wilen, James E..

This study examines the spatial nature of optimal bioinvasion control. We develop and parameterize a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal control strategies. We find that the qualitative nature of optimal strategies depend in interesting ways on aspects of landscape and invasion geometry. For example, we show that reducing the extent of exposed invasion edge, through spread, removal, or strategically employing landscape features, can be an optimal strategy because it reduces long-term containment costs. We also show that optimal invasion control is spatially and temporally “forward-looking” in the sense that strategies should be targeted to slow the...

Springer, A.; Tsioumanis, Asterios; Papastefanou, G.; Mattas, Konstadinos.

During the last few years the public has become in general more ambivalent towards new technologies and while expecting technological innovation to make their life better, they still old concerns about possible adverse effects deriving from the use of these technologies. The present paper offers a comparative approach on two European member countries concerning attitudes towards genetically modified food. The paper focus on values because previous research has shown that socio-economic factors can only partially explain differences in attitudes towards genetically modified food. Strong national differences lead to the idea that cultural differences should also be taken into account. Following the approach of Schwartz, the scope of this research paper is to...

Jonasson, Erik; Helfand, Steven M..

By paying particular attention to the local economic context, this paper analyzes rural non-agricultural employment and earnings in non-agricultural jobs. The empirical analysis is based on the Brazilian Demographic Census, allowing for disaggregated controls for the local economy. Education stands out as one of the key factor for shaping employment outcome and earnings potential. Failure to control for locational effects can lead to biased estimation of the importance of individual and household-specific characteristics. The empirical results show that local market size and distance to population centers have a significant impact on both non-agricultural employment prospects and earnings. The impact, however, is quantitatively larger for employment.

STUDENT NUMBERS AND SUSTAINING COURSES AND FIELDS IN PH.D. PROGRAMS

Davis, George C.; Perusquia, Ernesto.

Many agricultural economics departments are concerned about the vitality of their Ph.D. programs. A particular problem is insufficient student numbers to justify teaching certain courses or fields. As a consequence, much faculty time can be spent debating alternative program structures without any real idea of the likelihood that a proposed program structure will succeed. This article presents a framework for deriving some analytical and empirical results for alternative Ph.D. program structures. A downloadable program is used to generate some representative results that will hopefully help others minimize speculations and time spent in committee or departmental meetings.

When Should Uncertain Nonpoint Emissions be Penalized in a Trading Program?

Hennessy, David A.; Feng, Hongli.

When nonpoint source pollution is stochastic and the damage function is convex, intuition might suggest it is more important to control a nonpoint pollution source than a point source. Earlier research has provided sufficient conditions such that the permit price for a unit of ex-ante expected emissions should be higher than the permit price for a unit of certain emissions. Herein we provide a set of necessary and sufficient conditions such that this is the case. An approach to testing for the validity of the condition set is available, and has been applied to a related problem.
