Production risk,risk aversion and the determination of risk attitudes among Spanish rice producers

Agricultural production is subject to risk and the attitudes of producers toward risk will influence input choices insofar as these affect production risk. Risk attitudes in turn may be affected by certain socioeconomic characteristics of producers. Using 2004 survey data from a cross‐section of 130 Spanish rice farms, we estimate risk‐aversion coefficients of farmers and investigate the influence of a series of socioeconomic variables on their risk attitudes. Our results show that farmers exhibit risk‐averse behavior and that risk attitudes are related to a series of socioeconomic characteristics. In particular, the belief that the farm will continue after the producer retires is found to increase the degree of risk aversion, while age is found to have nonlinear effects on risk aversion. Off‐farm income, especially from nonagricultural activities, is found to reduce risk aversion. Neither the educational level of the producer nor the presence of dependents on the household is found to have an effect on risk preferences. Regarding the production technology, we find that land, labor, and fitosanitary products are risk‐reducing inputs, whereas capital, seeds, and fertilizer all increase risk.     

RISK ATTITUDES AMONGST AUSTRALIAN FARMERS

A procedure for the measurement of risk attitudes is developed and applied. The data for the analysis were obtained from a survey in which 201 farmers throughout Australia were asked to provide points of indifference between sure amounts of income and risky prospects. Although the conclusions from this pilot study are of a tentative nature, it is suggested that risk aversion is the most prevalent risk attitude in the agricultural sector. However, the average degree of risk aversion is relatively small and, in an expected utility context, farmers gave a wide variety of responses. The latter result highlights the need to consider the size distribution of risk attitudes in economic modelling. Influences of socioeconomic and other variables on risk attitudes are examined. The results, when considered jointly with other studies, emphasise the desirability of further research into the determination of risk attitudes.     

A conceptual framework of adoption of an agricultural innovation

In this paper we present a conceptual framework of individual farmers' decisions on adoption of a new innovation, using the example of a new crop species. This framework overcomes the shortcomings of a number of previous studies. It represents the adoption of an innovation as a dynamic decision problem spanning at least several years. The model allows for generation of potentially valuable information from trialing the innovation. The value of such trials is due to development of skills (e.g. in agronomic management of a crop) as well as reduction in uncertainty about the innovation's long-term profitability. The framework also includes the farmer's personal perceptions, managerial abilities and risk preferences in order to properly represent the adoption decision process. The influences of socio-demographic factors within the framework are discussed.     

The "People" Factor in Cooperatives: An Analysis of Members' Attitudes and Behavior

Members' attitudes and perceptions play a significant role in their behavior toward their organization and the performance of such organizations. This study examines the role of these “people” factors in a sample of fruit and vegetable growers' cooperatives in the Mid‐Atlantic United States. Although the Theory of Planned Behavior is used as the framework of analysis, the objective of this study was not to test the theory. Study findings provide additional insights into how cooperative members' beliefs and knowledge may shape their attitudes and the consequent behavior. Given the gradual decline of both cooperative memberships and the number of cooperatives in the United States and other countries, a good understanding of members' attitudes and behaviors is necessary because a cooperative's success may depend on it. Les attitudes et les perceptions des membres d'une coopérative jouent un rôle important dans le comportement envers l'organisme et la performance de ce dernier. La présente étude a examiné le rôle de ces facteurs ?humains? dans un échantillon de coopératives de producteurs de fruits et légumes dans les États du centre du littoral atlantique. Bien que la théorie du comportement axé sur un objectif ait été utilisée comme cadre d'analyse, l'objectif de l'étude ne consistait pas à tester la théorie. Les résultats de l'étude ont fourni des éclaircissements supplémentaires sur la façon dont les croyances et les connaissances des membres d'une coopérative peuvent façonner leurs attitudes et leur comportement subséquent. Compte tenu du déclin progressif du nombre de membres de coopérative et du nombre de coopératives aux États‐Unis et dans d'autres pays, il est important de bien comprendre les attitudes et les comportements des membres puisque le succès d'une coopérative peut en dépendre.     

The Influence of Consumer Characteristics and Attitudes on the Demand for Organic Olive Oil

Abstract

The aim of the present study is to examine consumer factors that affect the demand of organic olive oil (socioeconomic characteristics as well as attitudes towards organic products, food safety and the environment). Heckman approach for single equation procedure was applied in order to (1) identify the profile of regular buyers of organic olive oil based on the aforementioned factors and (2) to estimate income elasticity for the same product. Results indicate that the demand for or ganic olive oil is strongly affected by socioeconomic characteristics such as income size and occupation status, and to a lesser extent by attitudes towards organic products, food safety and the environment.     

Consumer trust, risk and food safety: A review

Consumers' attitudes to trust and risk are key issues in food safety research and attention needs to be focused on clearly defining a framework for analysing consumer behaviour in these terms. In order to achieve this, a detailed review of the recent literature surrounding risk, trust and the relationship between the two must be conducted. This paper aims to collate the current social sciences literature in the fields of food safety, trust and risk. It provides an insight into the economic and other modelling procedures available to measure consumers' attitudes to risk and trust in food safety and specifically notes the need for future research to concentrate on examining risk and trust as inter-related variables rather than two distinct, mutually exclusive concepts. A framework is proposed which it is hoped will assist in devising more effective research to support risk communication to consumers.     

Tenure security, resource poverty, public programs, and household plot-level conservation investments in the highlands of northern Ethiopia

Land degradation poses a serious problem for the livelihoods of rural producers. Furthermore, there is rarely enough private investment taking place to commensurate the scale of the problem. This article examines the role of tenure insecurity, resource poverty, risk and time preferences, and community‐led land conservation on differentiated patterns of household investment in land conservation in northern Ethiopia. We control for biophysical, household characteristics, market access conditions, and village level factors. Investments in soil bunds and stone terraces are specifically studied so as to capture the link between these various factors and the durability of conservation investments. We introduce the distinction between the determinants of the decision to invest and how much to invest in conservation. Regression results show that publicly led conservation programs seem to significantly stimulate private investment. A host of plot‐level variables and household perceptions of returns on conservation investments, expressed in terms of perceived improvements in land quality and increased crop yields, were found to be critical to the decision to invest and intensify soil conservation. The evidence on the significance of households' attitudes toward risk aversion suggests the important role of risk and the household's risk‐bearing capacity in the decision to intensify conservation measures. At the same time, tenure security indicators and households' resource endowments (resource poverty) had weaker effects in increasing willingness to invest and the level of investment made. The policy implications of these results point to the importance of agricultural research and extension efforts that target technologies which reduce household risk and poverty while enabling sustainable investments in conservation measures by individual households.     

The role of knowledge,attitudes and perceptions in the uptake of agricultural and agroforestry innovations among smallholder farmers in sub-Saharan Africa

Despite the great potential of agricultural innovations, the uptake by smallholder farmers in sub-Saharan Africa seems to be slow. We reviewed existing theories and frameworks for the uptake of agricultural innovations and found that these tend to emphasize the role of extrinsic factors such as the characteristics of the adopter and the external environment in the decision-making process. In this paper, we argue that intrinsic factors such as the knowledge, perceptions and attitudes of the potential adopter towards the innovation play a key role, but this has been less studied. We present an analytical framework that combines both extrinsic and intrinsic factors in farmers' decisions to adopt new agricultural technologies and apply the framework to agroforestry adoption as a case study. We review the literature on agroforestry adoption in sub-Saharan Africa and identify the extrinsic and intrinsic variables affecting the uptake of agroforestry technologies. We conclude that the uptake of agricultural technologies is a complex process influenced by both extrinsic and intrinsic variables, and recommend that future studies aiming to understand the adoption process of agricultural innovations take into account both sets of variables. A mechanistic understanding of how intrinsic and extrinsic factors interact and drive adoption can help in targeting technologies appropriately to ensure sustainability.

Risk Attitudes,Social Interactions,and the Willingness to Pay for Genotyping in Dairy Production

Bovine Mastitis is one of the most prevalent and costly production diseases in the dairy industry in Canada and worldwide causing major animal welfare problems, environmental problems, and productivity losses. In this paper, we examine the effects of risk attitudes and social interactions on the willingness to pay (WTP) for genotyping animals for susceptibility to a chronic mastitis trait. We use contingent valuation with double bounded dichotomous choice questions to elicit producers’ WTP. The estimated mean WTP for genotyping is approximately $50 per animal. Compared to the current market prices of commercially available comprehensive genotyping services, this estimate suggests a significant market potential for genotyping to be bundled with economically important disease traits. We also find evidence that both risk attitudes and social interactions have strong effects on the WTP for genotyping. Farmers with higher risk tolerance are willing to pay more for genotyping service. For dairy farmers with more concern about mastitis, risk tolerance has no significant effect on the WTP, while social interactions have a significant effect on the WTP. We also find a strong interaction effect between risk tolerance and social interactions. The findings encourage interest in questions about how risk attitudes, social networks, and their interactions shape the adoption of and the WTP for a novel agricultural technology. La mastite bovine est la maladie de production la plus répandue et la plus coûteuse de l'industrie laitière au Canada et mondialement causant des problèmes en ce qui concerne le bien‐être des animaux, l'environnement et la perte de productivité. Cet article examine les effets de l'attitude à l′égard du risque et des interactions sociales concernant la volonté de payer pour le génotypage d'animaux pour le dépistage de la susceptibilité à posséder le trait de mastite chronique. L'évaluation contingente avec questions à double proposition dichotomique a été utilisée afin d'obtenir la volonté de payer des producteurs. La volonté moyenne estimée de payer pour le génotypage s'élève à approximativement 50 $ par animal. Comparée aux prix courants du marché pour les services commerciaux complets de génotypage, cette estimation suggère un potentiel commercial significatif pour grouper le génotypage à d'autres traits de maladie d'importance économique. Nous trouvons aussi trouvé que les attitudes à l′égard du risque et les interactions sociales avaient un impact significatif sur la volonté de payer pour le génotypage. Les fermiers démontrant une grande tolérance au risque sont disposés à payer plus pour les services de génotypage. Pour les producteurs laitiers préoccupés par la mastite, la tolérance vis‐à‐vis du risque n'a aucun effet sur la volonté de payer, tandis que les interactions sociales en ont une importante. Nous notons aussi un effet significatif d'interaction entre la tolérance pour le risque et les interactions sociales. Les résultats favorisent un questionnement au sujet des attitudes à l′égard du risque, des réseaux sociaux et de leurs interactions, cherchant comment ces derniers guideront l'adoption de nouvelles technologies agricoles et la volonté d'en acquérir.     

Society's attitudes to and preferences for land and landscape

The relationship between society, land and landscape is deeply complex. Attitudes are reflected in behaviour, notably patterns of consumption through recreational activity, as well as in expressed preferences. Society attaches great importance to land. A large proportion of the population engages directly with it, through gardening and involvement in the management of allotments, community gardens and other public spaces. There is increasing evidence of the benefits of such engagement for individuals and communities. Society's attitudes and preferences have traditionally been dominated by expert or professional views, which have evolved over time and now place emphasis on everyday as well as special landscapes, and on urban greenspace and green infrastructure as much as on rural landscapes. The general public also seems to value the countryside as well as parks and green spaces nearer to home. Public attitudes are shaped by a number of different factors. Age, social and economic status, ethnic origin, familiarity, place of upbringing and residence, particularly whether urban or rural, are especially significant. Perhaps most important are environmental value orientations. At present, society seems to be polarised. At one extreme are older, more affluent, better educated, more environmentally aware people, often in social grades AB, who are often the most active users of the countryside and greenspaces. At the other extreme are younger age groups, ethnic minorities, and those who are in the DE social grades, who are often much less engaged. These groups have very different values and attitudes. But most people need to access and enjoy different types of landscape at different times and for different purposes, accessing what has been called a ‘portfolio of places’ that is particular to each person. It is by no means clear how the various factors that influence people's attitudes and preferences will play out in the future. Society may continue to become more detached from nature and landscape, and less caring about its future. Or there could be a rekindling of society's need to engage with the land and an increased desire to ensure that all sectors of society can benefit from green spaces and rural landscapes. This is likely to require interventions through education and campaigns to change attitudes and behaviour. Whether such initiatives can be effective in the face of competing drivers of attitudinal and behavioural change and over what timescale, may well determine how society's relationships with land and landscape evolve over the next 50 years.     

Spanish Household Demand for Seafood

Seafood is an important food commodity in Spain, the second largest consuming nation of seafood in the world. Today, several changes in demographics, socioeconomic factors, and lifestyle changes have affected demand for seafood products. Double‐hurdle models allow an examination of Spanish household expenditures on these products and explicitly account for the value of women's time. The empirical evidence shows that the set of statistically significant factors in the participation and expenditure equations is not the same for fresh and processed seafood goods. Income and household demographic variables are important determinants of both participation and expenditures on seafood products. In addition, the value of women's time affects expenditures on processed products, which include frozen, cured, and canned seafood goods.     

Evaluating Agricultural Energy Policies Under Uncertainty: The Case of Electricity in South India

Farmers' attitude towards risk associated with the availability of energy inputs will influence their investment behavior and demand for energy inputs. In order to analyze policies that reduce the risk in energy availability, some modifications in methods are required. This study, using a mean-variance framework, demonstrates how cross-sectional data and time-series data on crop yields and prices can be used to analyze agricultural energy policies under uncertainty in a developing country context. It is argued that the farmers risk attitudes, their crop allocation behavior, changes in the demand for energy inputs and the stochastic relationship between various forms of energy inputs can be explained by the various energy constraints faced by them. Furthermore, using the same methods the impact of policies which affect these constraints, can be analyzed.     

Planning for social inclusion: The impact of socioeconomic inequities on the informal development of farmland in suburban Beijing

Informal development on farmland is not only a major problem facing thousands of people, but also a major challenge to land use planning. In the rapidly growing literature on informal land development in China, most authors claim that ambiguous property rights and the dual land tenure system are the primary factors involved. As a result, existing state-led land use planning responses to informal development are solely focused on strengthening the legal regulation of land development. This paper challenges this approach, on the basis of the theory of urban informality. By examining many illegal gated communities in suburban Beijing, the paper argues that the informal development of farmland on the urban fringe is the result of local grassroots groups spontaneously responding to socioeconomic inequities in the context of transition to a market economy. These inequities mainly concern distributive inequity, procedural inequity and contextual inequity in relation to land use. It appears that the ongoing market-oriented initiatives of the state government could worsen informal land development unless these socioeconomic inequalities at the local level are tackled. The growing civil society is another change to the state's control of informal land development in China's cities. A new land use planning system which has more concern for social inclusion rather than focusing on centralized control is imperative in China.     

Race and affluence shape spatio-temporal urbanization trends in Greater Houston, 1997 to 2016

Urbanization results in increasing impervious surfaces with the potential to threaten fragile environments and heighten flood risks. In the United States, research on the social processes driving urbanization has tended to focus on the twenty-first century, but less is known about how temporal trends arose from the spatial layout of the urban land upon which this growth was founded. To address this gap, we present a novel interdisciplinary synthesis using neighborhood-level census data in tandem with a satellite-derived annual land cover change time series to assess the role of race, affluence, and socioeconomic status in shaping spatio-temporal urbanization in the Houston metropolitan area from 1997−2016. Results from cross-sectional and temporal regression models indicate that while social dynamics associated with historical versus recent urbanization are related, they are not identical. Thus, while temporal change in Houston's urbanization is driven primarily by socioeconomic status, the social dynamics associated with spatial disparities in urbanization relate primarily to race, regardless of socioeconomic status. These results are noteworthy as urbanization in Houston does not fully comport with existing theoretical perspectives or with empirical findings nationally. Instead, we suggest these findings reflect the city’s politics and culture surrounding land use. Thus, beyond its important social and environmental implications, this study affirms the utility of fusing socio-demographic data with satellite remote sensing of urban growth, and highlights the value of the socioenvironmental succession framework for characterizing urbanization as a recursive process in space and time.

Compensated optimal response under uncertainty in agricultural household models

This study derives the qualitative properties of a household's optimal consumption, family labour, hired labour and non-labour input choices under price and/or output risk through a Slutsky-type compensation without imposing any restriction on risk preference structure or production technology. These compensated responses provide the underpinning for welfare analysis in agricultural household models under risk. The framework for the evaluation of welfare effects of product and factor price interventions in a setting of output and price risk is developed. The paper also outlines an empirical model for estimation of the compensated demand and supply responses and for validation of the paper's analytical results.     

Non-parametric estimation of decision makers' risk aversion

A new non‐parametric method to estimate a decision maker's coefficient of absolute risk aversion from observed economic behaviour is explained. The method uses the expected value‐variance (E‐V) framework and quadratic programming. An empirical illustration is given using Norwegian farm‐level data.     

AGRICULTURAL TRADE LIBERALISATION AND THE URUGUAY ROUND*

With the Punta del Este Declaration, agriculture was accorded prominence in the GATT negotiations and, for the first time, national support policies were on the agenda. In this paper, the progress of the negotiations on agriculture is reviewed in an attempt to understand the factors which shaped the final outcome and to assess the likely impact of the round on liberalising agricultural trade. Although the immediate impact is likely to be modest, the round will provide longer term benefits to agricultural trade through the extension of the GATT rules-based system to agriculture. The framework which has been laid should provide a sound basis for future negotiations. Within the multilateral framework, the pace of change is a function of the willingness of all parties to compromise and this is evident in the Uruguay Round's outcome which reflects the European Union's agricultural reform agenda.     

African Perspectives on China–Africa: Modelling Popular Perceptions and their Economic and Political Determinants

China's recent political and economic inroads into Africa have generated much interest in the current literature, with scholars and policymakers endeavouring to assess the merits and risks implicit in this renewed engagement. Absent from the literature, however, are systematic analyses of African perceptions of these rapidly growing China–Africa links, and what determines these perceptions. This article fills this void by examining not only African attitudes towards China's African presence, but also investigating the considerations that inform these views. Using multi-level modelling techniques, this article estimates the effects of Chinese foreign direct investment (FDI), Sino-African trade and notions of democracy and human rights on African attitudes towards “China-in-Africa”. The results suggest that Africans' views of China are nearly equivalent to those that they hold vis-à-vis Western countries. The perceived impact of imports from China has a negative effect. However, this effect is counter-balanced by perceptions of China's impact on poverty alleviation—in line with its greater focus on economic, social and cultural, as opposed to civic and political human rights—in particular through FDI. Among those who value civic and political human rights, in contrast, attitudes towards China are less favourable. This finding is echoed with respect to democratic governance, though the effect is less stable. The results are derived from Afrobarometer data covering 20 African countries.
