Última U.S. State-Level Carbon Dioxide Emissions: A Spatial-Temporal Econometric Approach of the Environmental Kuznets Curve AgEcon Burnett, J. Wesley; Bergstrom, John C.. One of the major criticisms of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored. By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected by events in neighboring regions (i.e., assume there are no transboundary pollution emissions between neighbors). By ignoring the spatial aspects within the data several past estimates of the EKC could have generated biased or inconsistent regression results. By ignoring the temporal aspect within the data several past estimates of the EKC could have generated spurious regression results or misspecified t and F statistics. To address this potential...

Ano: 2010 URL: http://purl.umn.edu/96031 On aggregation bias in structural demand models AgEcon Lai, Pei-Chun; Bessler, David A.. Consumer demand analysis attracts considerable attention. It remains an open question, however, whether estimating demand with aggregate data is reliable when disaggregate store-level data is given. Demand models may produce biased results when applied to data aggregated across stores with different pricing strategies. In this study, the graphical model is used to investigate the following question: Do we find the same structure when we fit causal models on sub-groupings of stores, as we find when we fit models on aggregate data from all stores?

The cost efficiency of indicator-based targeting AgEcon Houssou, Nazaire; Zeller, Manfred. This paper assesses the cost efficiency of indicator-based targeting. Using household survey data from Malawi, we examine whether an indicator-based targeting of the poor is more target- and cost-efficient than the currently used mechanisms for targeting agricultural subsidy programs in the country. There is compelling evidence in favor of targeting Malawi’s poor based on the newly developed system. An indicator-based targeting system appears to be more target- and cost-efficient than the 2000/01 Starter Pack and the 2006/07 Agricultural Input Subsidy Program (AISP). While the Starter Pack and the AISP transferred about 50% of total transfer, under an indicator-based system, about 73% of transfers are delivered to the poor. Likewise, under an...

The New Member States did not yet have to implement the full cross-compliance package. Currently the GEAC requirements in the conditionality clause for the direct payments. The SMRs will become part of it starting from 2009. This paper looks into the Polish case and looks whether timely implementation is feasible. Several factors are mentioned, indicating that this will be a hard task. The problems with implementation explain why the new member states are advocating a gradual phasing in of the SMRs.

Este trabalho objetiva mensurar a volatilidade dos preços futuros do açúcar negociados na BM&F, bem como verificar quais entre os modelos univariados propostos apresenta melhor desempenho preditivo para o preço da commodity em questão. Para tanto se utilizam modelos de análise de volatilidade do tipo ARCH e modelos univariados de previsão aplicados a séries temporais, entre os quais os modelos ARIMA e SARIMA. Os resultados empíricos sugerem não haver presença de assimetria entre choques positivos e negativos e indicam a persistência na volatilidade dos preços do açúcar, implicando que os choques de volatilidade se dissiparão lentamente ao longo do tempo, podendo gerar perdas econômicas. Quanto aos modelos de previsão, o modelo ARIMA apresentou os...

Ano: 2008 URL: http://purl.umn.edu/108829 THE 'MILK QUOTAS RENT PUZZLE' IN THE EU: ECONOMIC SIGNIFICANCE, REVIEW, AND POLICY RELEVANCE AgEcon Jongeneel, Roelof A.; Tonini, Axel. In the so-called Common Agricultural Policy (CAP) 'Health Check' the European Commission has recently proposed gradual transitional measures to allow a 'soft landing' of the milk sector to quota expiry. The aim of this paper is to support policy makers to get better insights in the implications of some of the most important economic assumptions and empirical choices made in partial equilibrium models focusing on dairy. Three partial equilibrium models are considered: the Agricultural Member states MODeling (AGMEMOD) model, the Common Agricultural Policy SIMulation (CAPSIM) model, and the European Dairy Industry Model (EDIM). The paper analyzes how the most important economic supply components, as they are part of the three key dairy models, affect milk...

Ano: 2008 URL: http://purl.umn.edu/44796 Operational Models for Improving the Targeting Efficiency of Agricultural and Development Policies: A systematic comparison of different estimation methods using out-of-sample tests AgEcon Houssou, Nazaire; Zeller, Manfred. Accurate targeting is key for the success of any development policy. While a number of factors might explain low targeting efficiency such as governance failure, political interference or lack of political will, this paper focuses on improving indicator-based models that identify poor households and smallholder farmers more accurately. Using stepwise regressions along with out-of-sample validation tests and receiver operating characteristic curves, this paper develops proxy means tests models for rural and urban Malawi. The models developed have proved their validity in an independent sample and therefore, can be used to target a wide range of development policies to the poor. This makes the models a potentially interesting policy tool for the country.

Ano: 2009 URL: http://purl.umn.edu/51454 A meta-analysis of the response of calorie demand to income changes AgEcon Ogundari, Kolawole; Abdulai, Awudu. Over the past three decades, several studies have analyzed the response of calorie intake to income with varying and inconclusive results. This paper review these studies and employs meta-analysis to examine the potential bias in the calorie-income elasticity, as well as the impact of specific study attributes on these elasticities reported in the empirical literature. A total of 40 studies which yielded 99 estimated elasticities were considered. The results show the presence of publication (reporting) selection bias in the reported elasticities. Besides, the estimates revealed evidence of positive and significant empirical effect of income on calorie intake from all the studies that goes beyond publication bias. Study attributes such as ranking of the...

Ano: 2010 URL: http://purl.umn.edu/100873 MODEL TREE: AN APPLICATION IN REAL ESTATE APPRAISAL AgEcon Acciani, Claudio; Fucilli, Vincenzo; Sardaro, Ruggiero. In the last twenty years in real estate appraisal there has been a growing interest for new and reliable assessment techniques essentially through the introduction of pluriparametric estimate, in particular of linear regression. However, also these techniques seem having not a great deal of adherence to very complex markets, for which the detection of best suited techniques to investigate market segments is necessary. The aim of the research is to test the applicative possibilities of model tree to land market, in order to highlight possible market segments in the original data set not detectable a priori.

The aim of the paper is to reveal the most important causes of mobile telephony use by rural residents. In particular, the examination of the expected changes due to use of mobile phones and the assessment of the major causes that drive rural residents to desire mobile telephony access constitute the main objective of the paper. In addition, the study extends the employment of binomial econometric methodologies into rural development issues. Interesting results are revealed from the three discrete segments of rural populations regarding the drivers of mobile phone use. The majority of the users belong to the so-called “farmers”, where the dominant causes of mobile phone use are different from the rest ones. More specifically, causes such as region and...

Ano: 2010 URL: http://purl.umn.edu/95312 THE IMPACT OF II PILLAR ON THE MULTIFUNCTIONALITY IN ITALIAN FARMS: ANALYSIS ON THE FARM HOLIDAYS AgEcon Galluzzo, Nicola. This analysis has examined the relationships between the European funds for rural development and the multifunctionality during a short time, comparing two different situations before and after the Common Agricultural Policy (CAP) reform. The main problem was to find a variable able to describe the multifunctionality; the agritourism, in particular, number of farm holidays farms, has been the dependant variable useful to value the rural multifunctionality and the impact of the increase of II pillar fund. The Principal Component Analysis and the model of Ordinary Least Square have confirmed the positive impact of European Agricultural funds in the rural development and in the increase of active farm holidays farms.

Ano: 2008 URL: http://purl.umn.edu/44850 Agricultural Banking and Early Warning Models for the Bank Failures of the Late 2000s Great Recession AgEcon Li, Xiaofei; Escalante, Cesar L.; Epperson, James E.; Gunter, Lewell F.. This paper is designed to validate if the agricultural sector can once again be labeled as an instigator of the late-2000s Great Recession using the early warning models technique. The empirical results indicate that exposure to agribusiness operations does not necessarily enhance a banks’ tendency to fail.

Ano: 2012 URL: http://purl.umn.edu/119656 Del distrito industrial al distrito rural: implicaciones teóricas para el desarrollo territorial AgEcon Castillo, Juan Sebastián; García, María del Carmen. As opposed to the traditional Marshallian Industrial District, the Rural District becomes a new concept for territorial development thanks to the qualitative changes of population occurring since 1970 in developed countries and since 1980 in Spain and Castilla-La Mancha. The urban areas are decreasing in importance and the urban hierarchy and center-periphery relations evolved into less hierarchic and multipolar relations. Rural-rural movements occurred in rural environments, from minor cores to region cores and/or higher populated cores as a reproduction of a center-periphery model at rural territorial level.
