A Panel Data Analysis of the Repayment Capacity of Farmers AgEcon
Durguner, Sena.
Using a balanced panel of 264 unique Illinois farmers from 2000 to 2004, this study identifies the most pertinent factors that explain the repayment capacity of farmers. After correcting for endogeneity bias caused by farmer-specific effects, one year lagged debt-to-asset ratio and soil productivity are both found to be significantly correlated with the coverage ratio at the 5% significance level using random effects. The finding is significant because it can enhance agricultural lenders’ ability to assess creditworthiness, screen borrowers, manage loan loss reserves, and price loans, thereby decreasing lenders’ costs associated with defaulted loans and ultimately reducing the costs borne by the government and taxpayers.

An Examination of the Relationship Between Subsidies on Production and Technical Efficiency in Agriculture: The Case of Cotton Producers in Greece AgEcon
Emvalomatis, Grigorios; Oude Lansink, Alfons G.J.M.; Stefanou, Spiro E..
Subsidies on production have long been criticized for protecting producers from competition, and thus removing an incentive for efficient use of the resources. This study undertakes the examination of the impact of partially decoupled subsidies on the technical efficiency scores of cotton producers in Greece. The results indicate that compensatory area payments reduce the efficiency scores of the producers by diverting resources from products for which the subsidy is based on the area planted to the production of cotton, for which the aid is related to the volume of output.

Analisis Malmquist y DEA intertermporal de las agriculturas de la Union Europea AgEcon
Aldaz, Natalia; Millan, Joaquin A..
En este trabajo se realiza un análisis comparado de dos métodos no paramétricos de medida de productividad total de los factores con datos de panel basados en programación: índices de Malmquist y un modelo DEA intertemporal que permite acotar las medidas de eficiencia y progreso técnico, suponiendo cambio técnico no regresivo. La aplicación se realiza sobre las agriculturas de los países de la Unión Europea, encontrándose algunas diferencias importantes entre ambos enfoques. Los resultados sugieren menor crecimiento de productividad agraria y, sobre todo, una ordenación distinta de países en relación con dichos crecimientos que los encontrados en otros trabajos.

Analysis of Farm Development in Dutch Agriculture and Horticulture AgEcon
Bremmer, Johan; Oude Lansink, Alfons G.J.M.; Olson, Kent D.; Baltussen, Willy H.M.; Huirne, Ruud B.M..
This paper analysis the effects of farmer characteristics, farm structure and farm performance on farm renewal and farm growth. The data set used in this research consists of panel data from the Dutch Farm Accountancy Data Network of farms specialized in plant production extended with a data from survey among those farms. Probit models were used to determine the likelihood of the changes. Results show that the degree of mechanization increases the probability of farm growth and farm renewal. Family labour input and solvency have a negative impact on farm growth. Farm size is positively correlated with farm renewal. No indications of the influence of the life cycle have been found.

Analysis of international competitive positioning of quality wine from Spain Ciencia e Investigación Agraria
Castillo,Juan Sebastián; García,Mª Carmen.
J.S. Castillo, and M.C. García. 2013. Analysis of international competitive positioning of quality wine from Spain. Cien. Inv. Agr. 40(3): 491-501. The global vitiviniculture sector is undergoing systemic and thorough changes. Spain occupies a privileged position in the global industry, ranking first in surface area, third in production and second in export volume. In recent years, domestic consumption has experienced a clear and pronounced decline, as observed in France and Italy. Therefore, exportation has become the main commercial avenue for table and quality wine. In Spain, designated quality wine represents 50% of total production and has experienced commercial dynamics in international markets that differ from those affecting table wine. The object...

Augmented Gravity Model: An Empirical Application to Mercosur-European Union Trade Flows AgEcon
Martinez-Zarzoso, Inmaculada; Nowak-Lehmann, Felicitas.
This paper applies the gravity trade model to assess Mercosur-European Union trade, and trade potential following the agreements reached recently between both trade blocs. The model is tested for a sample of 20 countries, the four formal members of Mercosur plus Chile and the fifteen members of the European Union. A panel data analysis is used to disentangle the time invariant country-specific effects and to capture the relationships between the relevant variables over time. We find that the fixed effect model is to be preferred to the random effects gravity model. Furthermore, a number of variables, namely, infrastructure, income differences and exchange rates added to the standard gravity equation, are found to be important determinants of bilateral...

Bayesian Estimation of The Impacts of Food Safety Information on Household Demand for Meat and Poultry AgEcon
Taylor, Mykel R.; Phaneuf, Daniel J..
Consumer reaction to changes in the amount of food safety information on beef, pork, and poultry available in the media is the focus of this study. Specifically, any differences in consumer reactions due to heterogeneous household characteristics are investigated. The data used in this study are monthly data from the Nielsen Homescan panel and cover the time period January 1998 to December 2005. These panel data contain information on household purchases of fresh meat and poultry as well as demographic characteristics of the participating households. The data used to describe food safety information were obtained from searches of newspapers using the Lexis-Nexis academic search engine. Consumer reactions are modeled in this study using a demand system that...

Causes of Diversification in Agriculture Over Time: Evidence From Norwegian Farming Sector AgEcon
Culas, Richard J.; Mahendrarajah, Mahen.
Farm planning generally focuses on optimal diversification with respect to risk and uncertainties, where the risk-management strategies combine production, marketing, financial and environmental responses of the production of farm firm. In this study an empirical examination of farm diversification has been carried out from a sample of farms in Eastern Norway in which four measures of diversification (indices) were defined to incorporate the risk and uncertainties in relation to farm production (total) income. Using these four alternative measures of diversification and panel-data techniques, it has been shown that larger farms are more diversified, and when there is productive location and access to labour the farmers have a greater incentive to spread...

Causes of farm diversification over time: an Australian perspective on an Eastern Norway model AgEcon
Culas, Richard J..
Farm planning often focuses on optimal diversification with respect to risk, where the risk-management strategies combine production, marketing, financial and environmental aspects of the farm-firm. In this study an empirical examination of diversification has been carried out using a sample of farms in Eastern Norway. Four measures of diversification (indices) were defined to record the risks in relation to income from farm production. Using these alternative measures of diversification and panel-data, the results show that larger farms are more diversified, and for farms in more favourable locations and access to labour, the farmers have a greater incentive to spread risk. These results suggest that diversification and farm size are positively linked and...

Combating chronic poverty in Uganda: towards a new strategy AgEcon
Ssewanyana, Sarah N..
Using a panel of 3,572 households in the Northern Uganda Social Action Fund (NUSAF) region interviewed in 2004 and in 2008, the paper provides new evidence on chronic poverty in Uganda. While progress in reducing poverty rates has been impressive from 64.6 percent to 52.2 percent, the levels remain high with a significant number of persistently poor households. Four in every ten households are chronically poor of which 44.9 percent are living in extreme chronic poverty. About 37.8 percent of the households are living in transient poverty of which 67.4 percent escaped poverty during the panel period. The substantial movements out of poverty can perhaps be explained largely by the relative return of peace in the region that enabled households to engage in...

Combining mixed logit models and random effects models to identify the determinants of willingness to pay for rural landscape improvements AgEcon
Campbell, Danny.
This paper reports the findings from a discrete choice experiment study designed to estimate the economic benefits associated with rural landscape improvements in Ireland. Using a mixed logit model, the panel nature of the dataset is exploited to retrieve willingness to pay values for every individual in the sample. This departs from customary approaches in which the willingness to pay estimates are normally expressed as measures of central tendency of an a priori distribution. In a different vein from analysis conducted in previous discrete choice experiment studies, this paper uses random effects models for panel data to identify the determinants of the individual-specific willingness to pay estimates. In comparison with the standard methods used to...

COMPARISON OF AGRICULTURAL FARM EFFICIENCY IN SLOVAK REGIONS BEFORE AND AFTER EU ACCESSION AgEcon
Sojkova, Z.; Kropkova, Z.; Kovae, S..
This paper presents results of stochastic parametric approach used in estimation of farm technical efficiency. The estimation of output oriented technical efficiency was based on Stochastic Frontier analysis with Cobb-Douglas production function. Model specification for empirical application were employed Battese and Coelli 1995 model specification, where technical inefficiency effects are explicitly expressed as a function of a vector of firm-specific variables and random error and integrated in the stochastic frontier model. Model also included dummy variable which expressed production conditions in which Slovak farms are operating. We divided farms into two groups of production conditions: productive regions (PR) and less favorable area (LFA) regions....

Credit Accessibility, Risk Attitude, and Social Learning: Investment Decisions of Aquaculture in Rural Indonesia AgEcon
Miyata, Sachiko; Sawada, Yasuyuki.
This study examines the factors that influenced poor Indonesian farmers to invest in floating net aquaculture after being relocated due to a reservoir construction project. To compare three primary decision factors, credit accessibility, risk attitudes, and social learning, (i.e., learning effects from others’ experience), we analyze 16 years of socio-economic retrospective data collected in the field interviews exclusively for this study. Our analysis reveals that credit accessibility and risk attitudes are the most important factors that influence the rate of aquaculture investment. Social learning as well as household education also influences the investment decision significantly. Our results suggest that developmen t projects that involve voluntary...

Democratic Institutions and Environmental Quality: Effects and Transmission Channels AgEcon
Romuald, Kinda Somlanare.
This paper aims at analysing the effect of democratic institutions on environmental quality (carbon dioxide per capita, sulfure dioxide per capita) and at identifying potential channel transmissions. We use panel data from 1960 to 2008 in 122 developing and developed countries and modern econometric methods. The results are as follows: Firstly, we show that democratic institutions have opposite effects on environment quality: a positive direct effect on environment quality and a negative indirect effect through investments and income inequality. Indeed, democratic institutions attract investments that hurt environment quality. Moreover, as democratic institutions reduce income inequality, they also damage environment. Secondly, we find that the direct...

DETERMINANTS OF PART-TIME FARMING AND ITS EFFECT ON FARM PRODUCTIVITY AND EFFICIENCY AgEcon
Lien, Gudbrand D.; Kumbhakar, Subal C.; Hardaker, J. Brian.
Little attention has been given in the agricultural economics literature to the impact of off-farm work on farm productivity and efficiency. More knowledge about what determines part-time farming and whether farm productivity and efficiency are affected by part-time farming could help policy makers introduce better targeted rural development policies. This paper aims to fill the above-mentioned gaps by first analysing factors that influence the choice of off-farm work; and then examining how off-farm work influences productivity and technical efficiency at the farm level. An unbalanced panel data set from 1991 to 2005 from Norwegian grain farms is used for this purpose. The results show that the likelihood of off-farm work and the share of time allocated...

Die Zyklik der Profite in der Ernährungswirtschaft: Ein internationaler Vergleich AgEcon
Korner, Julia; Weiss, Christoph R..
Based upon the structure-conduct-performance approach the present paper analyses determinants of price-cost-margins over the business cycle for food industries in Germany, the USA as well as the Netherlands. Controlling for market structure variables, cyclical fluctuations in profitability are interpreted as evidence for changes in firm behaviour. The econometric panel data models reveal procyclic fluctuations of profits in highly concentrated industries in Germany. In contrast, profitability in competitive industries in Germany as well as in all US food industries are found to be more stable over the business cycle. This observation is explicable in terms of a more aggressive behaviour of firms in boom periods. The econometric model does not adequately...

Discussion: Applications and Innovations in Spatial Econometrics AgEcon
LeSage, James P..
These articles provide a discussion of studies presented in a session on spatial econometrics, focusing on the ability of spatial regression models to quantify the magnitude of spatial spillover impacts. Both articles presented argue that a proper modeling of spatial spillovers is required to truly understand the phenomena under study, in one case the impact of climate change on land values (or crop yields) and in the second the role of regional industry composition on regional business establishment growth.

Do private labels generate customer loyalty in food retailing? AgEcon
Wettstein, Nadine; Brosig, Stephan; Glauben, Thomas; Hanf, Jon Henrich; Loy, Jens-Peter.
The increase of private labels in food retailing and retailers' high expenditures for establishing them raise one central question: Do consumers really consider private labels as "real" brands and develop loyalty towards them. We analyse a four year panel data set on frozen pizza purchases to study differences in consumers' repurchasing behaviour between two strong national brands and private labels. In sum, our results show significant differences. However, the observable repurchase behaviour can not fully reflect the attitudinal component of brand loyalty. So subsequently, we present potential approaches to identify the underlying attitudinal component.
