Prospects of Chinese Grain Supply and Demand in 2010: A Regionalized Multimarket Model Simulation and Policy Implication AgEcon
Lu, Wencong C.; Kersten, Lutz.
Based on China's Agricultural Regional Market Equilibrium Model (CARMEM), the paper projects the production and consumption of rice, wheat and maize in China toward 2010 at both national and regional level under two different scenarios. The results show that China can ensure a stable grain market development under more liberalized internal and external conditions. Transmission of the world market prices as projected by the World Bank (2003) to the Chinese domestic market would lead to a long-run recovery of the growth in grain production. Total production of paddy rice, wheat and maize is forecast to increase from 386 million tons in the base period 2002 to over 420 million tons in 2010. However, the rate of grain self-supply will be 91% due to higher...

A Dynamic Decision Model of Technology Adoption under Uncertainty: Case of Herbicide-Resistant Rice AgEcon
Annou, Mamane Malam; Wailes, Eric J.; Thomsen, Michael R..
Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production. Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty. The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans. The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

HEALTH CHECK AND FARM EFFICIENCY: A COMPARATIVE ASSESSMENT OF FOUR EUROPEAN AGRICULTURAL REGIONS AgEcon
Arfini, Filippo; Donati, Michele.
The European Commission has always considered the Common Agricultural Policy (CAP) as a dynamic political tool that aims to link the agricultural sector with the evolving of the economic, financial, social and political dynamics that distinguish the Member States of the European Union. From this standpoint, the Health Check (HC) is much more than a simple assessment of the state of health of European agriculture; it is a drawing up of the “new rules” that are to manage the relations between farms and the market, on which the future efficiency and survival of the said farms and the production sectors that characterise entire European agricultural regions will depend. In this context, the aim of this paper is to present and analyse the "innovations" of the...

Rates of Return in the Farm and Nonfarm Sectors: How Do They Compare? AgEcon
Erickson, Kenneth W.; Moss, Charles B.; Mishra, Ashok K..
This study examines the return on agricultural assets relative to nonfinancial corporate assets in the general economy using aggregate bureau of Economic Analysis data. Our results indicate that the rate of return on nonfarm assets dominates the rate of return on agricultural assets. The average rate of return on nonfarm assets is higher than the average rate of return on farm assets, and the variance of the rate of return on nonfarm assets is lower than the variance of the rate of return on farm assets. Furthermore, the rate of return on agricultural assets only exceeds the rate of return in the nonfarm sector in 1992.

Wealth, Living Standards and Perceptions in a Cotton Economy: Evidence from the Cotton Reform in Burkina Faso AgEcon
Kaminski, Jonathan.
The cotton economy of Burkina Faso has been characterized by a changing rural environment for farmers since late nineties, which has come with the cotton reform and the resulting cotton boost. There have been slight improvements in living standards and rural households’ income while the subjective feeling of wealth has significantly increased. In this paper, I explore the channels through which the elements of the changing rural environment can bridge the wedge between subjective and objective measures of wealth. In addition to the basic determinants of subjective welfare that can be found in the happiness economics literature, namely absolute and relative income measures, health and social status (and expectations of future incomes), I investigate the...

The Economic and Historical Foundation of the Common Agricultural Policy in Europe AgEcon
Zobbe, Henrik.
The Common Agricultural Policy (CAP) was founded in the 1950s with price support as the main policy instrument. Despite massive criticism from both within and outside the EU, price support remains the backbone of the CAP. This paper argues that the choice of price support was logical viewed in both historical and economical perspectives, and gives three reasons for this. First, even though talks on agricultural integration began immediately after the war, the CAP was a result of general economic integration in Europe rather than the reason for it. Second, the structure of the CAP was determined by the agricultural policies of the six founding countries. The third and last reason is related to the economic characteristics of running a price support system....

Carbon Labeling for Consumer Food Goods AgEcon
Shewmake, Sharon; Okrent, Abigail M.; Thabrew, Lanka; Vandenbergh, Michael.
We construct a model to predict how consumers will respond to better information about the carbon content of 42 foods and a nonfood composite as well as product categories through a label, and provide guidance as to what kinds of goods would provide the highest CO¬2eq emission reductions through a labeling scheme. Our model assumes that consumers value their individual carbon footprint, allowing us to utilize estimates of own- and cross-price elasticities of demand from the literature on demand analysis. We make three different assumptions about how consumers currently value their carbon footprint and find that when a label informs consumers, their baseline perception matters. We also find that carbon labels on alcohol and meat would achieve the largest...

Extending General Equilibrium to the Tariff Line: U.S. Dairy in the DOHA Development Agenda AgEcon
Grant, Jason H.; Hertel, Thomas W.; Rutherford, Thomas F..
Market access has been at the core of eight negotiating rounds of the General Agreement on Tariffs and Trade (GATT). Yet, agricultural trade remains a heavily protected sector, characterized by higher tariffs relative to industrial goods, large tariff dispersions, numerous specific tariffs and systems of tariff-rate-quotas. This has made the analysis of trade liberalization a formidable task among policy analysts. Previous studies of agricultural trade liberalization have used partial or general equilibrium models of trade. However, each of these modeling strategies has their drawbacks. General equilibrium (GE) models have been criticized because they face serious aggregation issues and miss much of the policy detail that occurs at the tariff line. Partial...

The Effect of Policy and Policy Reforms on Non-Agricultural Enterprises and Employment in Developing Countries: A Review of Past Experiences AgEcon
Haggblade, Steven; Liedholm, Carl; Mead, Donald C..
This paper explores two sets of issues. The first concerns the magnitude of policy induced distortions in developing countries and the impact of these distortions on the economy, paying special attention to differential impacts between firms of different sizes and resulting effects on the level of employment. The second concerns the prior experience of donors and the LDC governments with the process of policy change.

Analysis of Commodity Program Adjustments for U.S. Rice in Stochastic Framework AgEcon
Chavez, Eddie C.; Wailes, Eric J..
Potential adjustments in U.S. commodity program for rice are evaluated in this paper using stochastic analysis in a global modeling framework. Corresponding threshold and loss-compensatory increases in target price and loan rates are determined with assumed outright and gradual elimination of direct payments. Results show that if direct payments (DP) are eliminated in 2012, a 23% increase in both the target price (TP) and loan rate (LR) triggers counter-cyclical payments (CCP) 80% of the time; and it will take an increase of 48% in TP and LR to generate CCP enough to compensate for the loss in total DP. If DP is gradually removed over 5 years, the trigger and compensatory increases in TP and LR are 41% and 46%, respectively. Furthermore, if DP is...

MEASURING CROSS-SUBSIDISATION OF THE SINGLE PAYMENT SCHEME IN ENGLAND AgEcon
Renwick, Alan W.; Revoredo-Giha, Cesar.
The specific purpose of this paper is to estimate the extent to which decoupled payments under the Single Payments Scheme (SPS) are being used (either explicitly or implicitly) in England to support the continuation of activities that were previously supported by area and headage payments. In the absence of a farm survey, the methodology consists of using information on farm accounts collected through England’s Farm Business Survey (FBS), to estimate a multi-output cost function differentiated by farm size and farm type. This cost function, calibrated to match regional prices in England, is used to estimate the level of cross-subsidisation in the first full year after implementation of the SPS (2005/06). Results indicate that cross-subsidisation was...

A Survey of Literature on Genetically Modified Crops: Economics, Ethics and Society AgEcon
White, R. McKay; Veeman, Michele M..
This paper reports on a review of literature in the form of academic papers and published research on ethical and consumer issues for GM crops in North America, with particular emphasis on GM wheat. The issues raised in these papers and the findings and arguments posed by the authors are outlined. A general conclusion that can be drawn from this overview is that public attitudes toward GM foods are diverse and sometimes quite strongly held. The strong negative views of GM food held by some appear to be mainly grounded in individuals’ ethical or moral values. Ethical and risk assessment issues have not been fully explored in the existing literature. There is a general consensus in the applied economics literature that GM crops result in economic benefits,...

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...

Agricultural Change and Population Growth: District-Level Evidence From India AgEcon
Witcover, Julie; Vosti, Stephen A.; Lipton, Michael.
Green Revolution technologies were developed and promoted in the 1960s in response to alarm about impending famine in Asia. By boosting food supplies and fostering development, the technologies were expected to create "breathing space" for completing demographic transitions there. This paper uses District-level data from rural India on agricultural transformation (from 1961 to 1981) and on changes in human fertility (from 1971 to 1981) to examine whether they did so. In a reduced form model, female literacy and marriage rates emerged as strong fertility change determinants; effects varied by age cohort. Growth in real wages in rural areas, in part brought about by HYV technologies, accelerated fertility declines. With real wage growth effects of Green...

Consumer's WTP for Environment-Friendly Production Methods and Collective Reputation for Place of Origin: The Case of Val di Gresta's Carrots AgEcon
Scarpa, Riccardo; Thiene, Mara; Marangon, Francesco.
This paper investigates preferences for various environment-friendly production system for carrots using discretechoice multi-attribute stated-preference data amongst buyers and explore the effect of collective reputations from growers of an Alpine valley known to be completely dedicated to organic production. Results show that buyers distinctly recognize only organic production as a production system different from the conventional one, and there is some evidence of recognition of collective reputation. As well as for marginal utility of income, substantial unobserved heterogeneity is found for many skin imperfections, origin from the organic Alpine valley and the organic production methods. The implied sample distributions of WTP for each of these random...

ON THE EFFECTIVENESS OF PRIVATE FOOD STANDARDS AgEcon
Giraud-Heraud, Eric; Grazia, Cristina; Hammoudi, Abdelhakim.
This paper provides an original theoretical framework to better understand the raise of private quality standards in agrifood chains. Reasons for the development and conditions for the effectiveness of private quality standards are identified, by investigating firms’ strategic behaviour and, more precisely, both interactions among processing/retailing firms and upstream producers and the role of consumers’ behaviour. Considering different levels of consumers risk perception, we show that the incentive for firms to develop a more stringent private standard may increase with the level of the regulated minimum quality standard. Moreover, setting a private standard may reduce the risk of consumer dissatisfaction while increasing the marketed quantity....

Consumer Willingness to Pay for Food Safety in Beijing: A Case Study of Food Additives AgEcon
Liu, Yuanyuan; Zeng, Yinchu; Yu, Xiaohua.
Constructing a theoretical framework and using a survey data of 294 customers from 25 supermarkets in Beijing, this paper studies the willingness to pay (WTP) for additive-free Mooncakes in Beijing and finds that age and income are important for WTP for “food safety” in China. Income is positively correlated with the WTP and there is an inverted-U-shaped relationship between age and WTP. This study indicates that consumers in Beijing are willing to pay 5.80 Yuan more for an additive-free Mooncake, which provides a good policy benchmark for the government regulation on food additives. Furthermore, the theoretical framework also provides a good benchmark for understanding WTP in the future study of food safety.

Technical Efficiency in Organic Farming: An Application on Italian Cereal Farms Using a Parametric Approach AgEcon
Madau, Fabio A..
A stochastic frontier production model was applied to estimate technical efficiency in a sample of Italian organic and conventional cereal farms. The main purpose was to assess which production technique revealed higher efficiency. Statistical tests on the pool sample model suggested that differences between the two cultivation methods were significant from a technological viewpoint. Separate analyses of two sub-samples (93 and 138 observations for organic and conventional farms, respectively) found that conventional farms were significantly more efficient than organic farms, with respect to their specific technology (0.892 vs. 0.825). This implies that organic (conventional) cereal farmers could increase their income to 99.19 €/ha (40.95 €/ha). Analysis...
