A Közös Agrárpolitika reformja magyar (kutatói) szempontból AgEcon
Udovecz, Gabor.
Az EU Közös Agrárpolitikája az állandó kompromisszumok és a sorozatos reformok terméke. Most annyiban más a helyzet, hogy a döntéshozatali mechanizmusban a szokásosnál is nagyobb a társadalmi nyomás, emiatt pedig a pénzügyi determináltság. A jövő alakításában pedig mi magyarok is részt veszünk. Kivételes lehetőség tehát, hogy hazánk adottságai (erősségek, gyengeségek) alapján határozott agrárorintációt fejezzen ki, s ennek fő törekvéseire építse az ország KAP-álláspontját. Magyarország olyan KAP-ban érdekelt, amely – európai értékek mentén – minél több uniós forrást biztosít, de tágítja is a mozgásteret a nemzeti agrár- és vidékpolitikai célok megvalósításához. Összefoglalóan kiemelhető, hogy a KAP-reform döntési mechanizmusa bonyolult, Magyarország...

A Performance Analysis of the Supply of Public Goods in Rural Communities Based on the System Implementation Costs - Taking Chongren county Bailu village, Taihe County Yongchang village as examples AgEcon
Zheng, Shuang-sheng.
Based on the survey of Chongren county Bailu village, Taihe county Yongchang village and by focusing on the system implementation costs, the public goods is divided into tangible products and intangible products these 2 parts to carry out a perfomance analysis of the supply of public goods in rural communities. It points out that in both the well-acquainted and rare-acquainted communities in rural areas there are some long-existing informal systems, such as religions. Because of their born nature, the system implementation costs are relatively lower. However, the implementation costs of the embedded foreign systems are relatively higher because of their weaker lasting features and the rare social basis. Therefore, proposing putting the efficient supply of...

A vision of the future of the Common Agricultural Policy AgEcon
Elkes, Andrea; Halmai, Peter; Papp, Gergely; Udovecz, Gabor; Vasary, Viktoria.
The reforms proposed by the authors intend to ensure the economic, social and environmental sustainability of rural regions and place agricultural policy on a fundamentally different basis. The scope of community and state intervention will change. Payments linked to production will be cancelled and the provision of public goods will be rewarded instead. At the same time, measures aimed at enhancing the viability of the rural economy and society will become more significant. The depth of the changes calls for a new name expressing better the new approach, so instead of CAP the use of a more justified name is suggested: Common Agricultural and Rural Policy (CARP). This paper outlines the vision and the major proposals we suggest to meet the above mentioned...

Can Calibration Reconcile Stated and Observed Preferences? AgEcon
Norwood, F. Bailey.
Hypothetical bias is a pervasive problem in stated-preference experiments. Recent research has developed two empirically successful calibrations to remove hypothetical bias, though the calibrations have not been tested using the same data or in a conjoint analysis. This study compares the two calibrations in a conjoint analysis involving donations to a public good. Results find the calibrations are biased predictors of true donations but that calibrated and uncalibrated models together provide upper and lower bounds to true donations.

COMMON FINANCING FOR AGRICULTURAL POLICY BUDGETARY QUESTIONS AgEcon
Vasary, Viktoria; Elekes, Andrea; Halmai, Peter.
Can we agree fully with the statement, that “agricultural spending is a major distorting factor in the EU economy and a distinct obstacle to the Lisbon agenda’s implementation”? (Gros, 2008) Is it without question that Europe’s agriculture is in position to become sustainable and competitive without certain kind of common policy with no Community financing? Is it unambiguous in every respect, that the challenges facing the sector – globalization, trade liberalization, climate change, water management, Lisbon process, enlargement, changing preferences – could be answered at national level utilizing exclusively national financial sources? The answers to these questions are complex. So the purpose of the paper is multiple: - Exploration of factors justifying...

Community versus National Financing - How to achieve a sustainable agricultural policy? AgEcon
Halmai, Peter; Vasary, Viktoria.
Is the Common Agricultural Policy unsustainable? Is agricultural spending a major distorting factor in the EU economy and an obstacle to the implementation of the Lisbon agenda? To answer these complex questions, detailed analysis is required along the following lines of thought: 1. Exploration of factors justifying Community level intervention. – Is the ’theory of decentralization’ applicable to budgetary issues and the common agricultural policy? Our hypothesis suggests that it is. 2. Assessing CAP as it currently exists, including its ability to generate public goods at the level of the Community (multifunctional elements which are indeed cross-border externalities) and its ability to create added value at the level of the Community. 3. Making an...

Comparing the Effectiveness of Regulation and Pro-Social Emotions to Enhance Cooperation: Experimental Evidence from Fishing Communities in Colombia AgEcon
Lopez, Maria Claudia; Murphy, James J.; Spraggon, John M.; Stranlund, John K..
This paper presents the results from a series of framed field experiments conducted in fishing communities off the Caribbean coast of Colombia. The goal is to investigate the relative effectiveness of exogenous regulatory pressure and pro-social emotions in promoting cooperative behavior in a public goods context. The random public revelation of an individual’s contribution and its consequences for the rest of the group leads to significantly higher public good contributions and social welfare than regulatory pressure, even under regulations that are designed to motivate fully efficient contributions.

Cooperation and bacterial pathogenicity: an approach to social evolution RChHN
Alfonso Molina,C; Vilchez,Susana.
Kin selection could provide an explanation for social behavior in bacteria. The production of public goods such as extracellular molecules is metabolically costly for bacteria but could help them to exploit nutrients or invade a host. Some bacterial cells called social cheaters do not produce public goods; however, they take advantage of these extracellular molecules. In this review, the relationships between social behavior, cooperation, and evolution of bacterial pathogenicity are analyzed. This paper also examines the role of horizontal transfer of genes encoding for virulence factors and how the movement of mobile genetic elements would influence the pathogenicity and social relationships. Moreover, the link between ecological relationships and...

Does Government Regulation Complement Existing Community Efforts to Support Cooperation? Evidence from Field Experiments in Colombia AgEcon
Lopez, Maria Claudia; Murphy, James J.; Spraggon, John M.; Stranlund, John K..
In this paper we describe a field experiment conducted among mollusk harvesters in a community on the Pacific Coast of Columbia. The experiment is based on a standard linear public good and consists of two stages. In the first stage we compare the ability of monetary and nonmonetary sanctions among community members to increase contributions to the public good. In the second stage we add a government regulation with either a high or low sanction for noncompliance to community enforcement efforts. The results for the first stage are consistent with other comparisons of monetary and nonmonetary sanctions within groups; both led to higher contributions. The results from the second stage reveal that government regulations always complemented community...

Finnish Citizens' Attitudes towards Multifunctional Agriculture AgEcon
Hyytia, Nina; Kola, Jukka.
This paper examines Finnish citizens' attitudes towards multifunctional agriculture and further, the connections among these attitudes, consumers' willingness to pay, and some socio economic factors. Attitudinal dimensions were executed by using factor analysis. The respondents (N=1300) were distributed into clusters based on their attitudes. It would be expected that people who have positive attitudes, would also state high values of WTP. Instead, this study suggests that attitudes and open-ended WTP do not have a positive relation. People are willing to support domestic agriculture as a provider of safe and high-quality food. However, a remarkable proportion of Finnish citizens have a positive attitude towards externalities and joint products of...

Fiscal Policies in Highly Unequal Societies: Implications for Agricultural Growth AgEcon
Lopez, Ramon E..
The paper discusses the economic effects of misallocation of public expenditures in favor of private goods rather than public goods. It first lays out certain key hypotheses regarding the consequences of the apparent public sector allocation inefficiency and the factors that explain this phenomenon. It then discusses existing empirical evidence that lends at least indirect support to these hypotheses. Finally, it presents new empirical evidence for the rural sector in Latin America which documents the extent of the misallocation of public expenditures, its consequences for agricultural growth and rural poverty, and the role of certain key politico-institutional factors in explaining the misallocation.

Generating Revenues from WTP for Ecosystem Restoration: An Auction Experiment on Public Goods AgEcon
Smith, Elizabeth C.; Swallow, Stephen K..
Research on public good auctions is intended to initiate development on new approaches to finance public goods, beyond government and philanthropic efforts. The researchers evaluate the potential to identify economic value for a subset of ecosystem services and markets that have the potential to provide for them. Empirical analysis focuses on public valuation for three specific types of ecosystem activities (bird habitat, sea grass restoration and shellfish restoration) in coastal Virginia. Data was collected using a field experiment employing an experimental auction approach with mechanisms to reduce free riding often seen in the experimental economics literature. These incentive mechanisms are applied to individual restoration activities and willingness...

Global responsibility of food, energy and environmental security AgEcon
Popp, Jozsef.
This paper focuses on global responsibility of food, energy and environmental security. World population growth will lead to increasing demand for food and feed with increasing meat consumption. With globalization and urbanization production is moving to the most competitive countries and regions, and food trade is becoming more liberalized but also more concentrated. Growing energy demand and climate change will also influence food production. Additional challenges are increasing market volatility resulting from yield and climate change. We need greater responsibility in cutting greenhouse gas (GHG) emissions, in showing greater respect for the environment. More responsibility is needed regarding food and energy security, and environmental sustainability....

Green Giving: An Analysis of Contributions to Major U.S. Environmental Groups AgEcon
Richer, Jerrell.
Data are compiled from the tax records of 29 major environmental organizations for the period 1980-1994 to identify factors that influence voluntary contributions. I examine the effects of organizational characteristics, such as fundraising expenditures and alternative sources of revenue, along with the impact of general economic conditions and the political climate. I find that government grants to the organizations had a positive and statistically significant impact on voluntary contributions rather than a crowding out effect. Contributions were price inelastic, where the price is defined as the effective cost to the donor of achieving a one-dollar increase in the provision of program services. Resources devoted to fundraising had a strong and positive...

Hogyan érvényesítheti az alkotmány a föld közfunkcióit? AgEcon
Tanka, Endre.
A történelmi korszakváltás a fenntarthatóság egyik létfeltételévé teszi, hogy a birtokrendben az állam közhatalmi beavatkozással érvényesítse a föld társadalom- és gazdaságszervező közfunkcióit. Ennek jogi pillére olyan alkotmányos intézmény lehet, amely a Magyar Állam területét alkotó termőföldet tulajdoni formájától függetlenül a nemzet vagyonának minősíti. Az állam az államterületét alkotó, földre fennálló alkotmányos önrendelkezési joga alapján valamennyi jogalanyra kiterjedően szabályozza és közérdekből korlátozhatja a termőföld-tulajdonszerzés és a földhasználat feltételeit. Magyarország a földmoratórium uniós meghosszabbításával a közérdekű birtokpolitika megvalósítására további három évet nyert, és a föld nemzeti vagyonná minősítése alapján...

Knowledge and the Valuation of Public Goods and Experiential Commodities: Information Provision and Acquisition AgEcon
Tisdell, Clement A..
Provides empirical evidence of significant lack of relevant knowledge of some public goods and experiential commodities. It also analyses whether information provision about the attributes or characteristics of commodities is likely to result in individuals’ finding their ‘true’ preferences for these, and identifies the type and nature of information that should be conveyed to enable commodities to be appropriately valued. It also recognizes that sometimes commodities may contain attributes that individuals are unable to evaluate. Furthermore, individuals acquire and filter information about commodities. Factors influencing these activities require analysis. A cost-benefit analysis of information acquisition suggests that individuals are less likely to...

Learning, Signaling, and Social Preferences in Public-Good Games Ecology and Society
Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu; Ahn, T. K.; Florida State University and Korea University; tahn@fsu.edu.
This study compares the empirical performance of a variety of learning models and theories of social preferences in the context of experimental games involving the provision of public goods. Parameters are estimated via maximum likelihood estimation. We also performed estimations to identify different types of agents and distributions of parameters. The estimated models suggest that the players of such games take into account the learning of others and are belief learners. Despite these interesting findings, we conclude that a powerful method of model selection of agent-based models on dynamic social dilemma experiments is still lacking.

Matching Grants and Charitable Giving: Why People Sometimes Provide a Helping Hand to Fund Environmental Goods AgEcon
Kotani, Koji; Messer, Kent D.; Schulze, William D..
Matching grants are a prevalent mechanism for funding environmental, conservation, and natural resource projects. However, economists have largely been silent regarding the potential benefits of these mechanisms at increasing voluntary contributions. To examine the behavioral responses to different match levels, this research uses controlled laboratory experiments with generically framed instructions and introduces a general-form matching-grant mechanism, referred to as the proportional contribution mechanism (PCM). Results show that contributions are positively correlated with both the match and the induced value of the public good even when a dominant strategy is free-riding. An implication of this partial demand revelation result is that manifestations...

Multifunctionality: Concepts and Applications to the WTO Negotiations on Agriculture AgEcon
Bredahl, Maury E.; Prestegard, Sjur Spildo; Nersten, Nils Kristian.
The ongoing negotiations in the WTO will most certainly lead to a further liberalization of the global agricultural trade. Related to this, many national governments, including Norway, Switzerland and Japan have placed substantial emphasis on the so-called non-trade concerns. In addition to the production of food and fiber, agriculture also provides or may provide national food security, environmental benefits, and viable rural areas. The term "Multifunctional Agriculture" has been applied to describe these additional functions. In this paper, we will show how the economic concepts of "positive and negative externalities" and "public goods" can be used to analyse non-trade concerns and multifunctionality, especially with reference to agriculture's impact...
