The Persistence of Poverty in Rural China: Applying an Ordered Probit and a Hazard Approach AgEcon
Glauben, Thomas; Herzfeld, Thomas; Wang, Xiaobing.
The present study investigates the analysis of poverty persistence of Chinese farm households in the well-off Zhejiang province in the southeast. We firstly apply an ordered probit model examining household, farm, and regional characteristics affecting the probability that households are chronically poor. In addition, we apply a hazard approach to identify the risk of falling into and climbing out of poverty. Results indicate that there are increasing chances to climb out of poverty over time, and that the risk of falling into poverty seems to decrease after the household spent some time outside poverty.

The Right Amount of Trust AgEcon
Butler, Jeffrey; Giuliano, Paola; Guiso, Luigi.
We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs. Heterogeneity of trust beliefs in the population, coupled with the tendency of individuals to extrapolate beliefs about others from their own levels of trustworthiness, could generate this non-monotonic relationship: highly trustworthy individuals tend to form overly optimistic beliefs, to assume too much social risk and to be cheated more often, ultimately performing less well than those with a belief close to the mean trustworthiness of the population. On the other hand, less trustworthy individuals form overly pessimistic beliefs and avoid being cheated, but give up...

THE INFLUENCE OF ATTRIBUTE CUTOFFS ON CONSUMERS’ CHOICES OF A FUNCTIONAL FOOD AgEcon
Ding, Yulian; Veeman, Michele M.; Adamowicz, Wiktor L..
This study investigates evidence of non-compensatory preferences by incorporating attribute cutoffs into the modeling of consumer choices in the context of food with health-related attributes (omega-3 content) that may be associated with fortification or may result from genetic modification (GM). Data for this study were collected through a nation-wide internet-based survey drawn from a representative panel of Canadian households maintained by a major North American marketing firm. In addition to querying respondents on their perceptions and attitudes regarding food and health, choices of canola oils are elicited using a stated choice experiment in which product alternatives are identified based on attributes of price, country of origin, omega-3 content...

Coping with Drought in Rice Farming in Asia: Insights from a Cross-Country Comparative Study AgEcon
Pandey, Sushil; Bhandari, Humnath; Ding, Shijun; Prapertchob, Preeda; Sharan, Ramesh; Naik, Dibakar; Taunk, Sudhir K.; Sastri, Asras.
Drought is a major constraint affecting rice production especially in rainfed areas of Asia. Despite its importance in rice growing areas, the magnitude of economic losses arising from drought, its impact on farm households and farmers' drought coping mechanisms are poorly understood. This paper provides insights into these aspects of drought based on a cross-country comparative analysis of rainfed rice growing areas in China, India and Thailand. The economic cost of drought is found to be substantially higher in eastern India than in the other two countries. Higher probability and greater spatial covariance of drought and less diversified farming systems with rice accounting for a large r share of household income are likely to be the main reasons for...

Factors Influencing the Success Potential in Smallholder Irrigation Projects of South Africa: A Principal Component Regression AgEcon
Magingxa, Litha Light; Alemu, Zerihun Gudeta; van Schalkwyk, Herman D..
The objective of this paper is to examine the role of the factors expected to influence the success potential of small holder irrigation projects as they apply in the South African context. The study was conducted in six smallholder irrigation schemes in three provinces namely: Eastern Cape, Limpopo and Mpumalanga. To determine the farmers' potential success (dependent variable), a cluster analysis was conducted yielding two groups of farmers - the less successful and more successful. The principal component regression (PCR) tool was used to analyse the data and deal with the problem of multicollinearity, transforming the explanatory variables into principal component estimators. There were fourteen explanatory variables. Out of the nine statistically...

Determinants of Decision to Pay a Price Premium for Modified Food by Consumers of the Republic of Korea AgEcon
Kaya, Ozgur; Florkowski, Wojciech J.; Suh, Dong-Kyun.
The knowledge of the overall willingness-to-pay and the specific price premiums consumers accept when buying foods with less fat, saturated fat, sodium, sugar and more fiber shapes food manufacturer and distributor marketing strategies and supports the development of public health strategies. This study applies survey data collected in Korea to identify consumer profiles associated with the expressed willingness to pay a premium for foods with nutritionally desired attributes and, next, estimates the influence of consumer and household characteristics on the WTP a particular premium level for such foods. Results indicate the importance of socio-economic variables such as location, income and education, variables representing the risk of health problems...

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...

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...

India Edible Oil Consumption: A Censored Incomplete Demand Approach AgEcon
Pan, Suwen; Mohanty, Samarendu; Welch, Mark.
A Censored Incomplete Demand System is applied to household expenditures for edible oil in India. The results show that edible peanut oil is still a luxury good in India, whereas expenditure elasticities for other edible oils are relatively low. The food habit, location, education of household heads, and other demographic variables have significant effects on the choice of edible oils.

Short-Run Demand Relationships in the U.S. Fats and Oils Complex AgEcon
Goodwin, Barry K.; Harper, Daniel C.; Schnepf, Randall D..
Fats and oils play a prominent role in U.S. dietary patterns. Recent concerns over the negative health consequences associated with fats and oils have led many to suspect structural change in demand conditions. Our analysis considers short run (monthly) demand relationships for edible fats and oils. In that monthly quantities of fats and oils are likely to be relatively fixed, an inverse almost ideal demand system specification is used. A smooth transition function is used to model a switching inverse almost ideal demand system that assesses short-run demand conditions for edible fats and oils in the United States. The results suggest that short-run demand conditions for fats and oils experienced a gradual structural shift that began in the late 1980s...

Consumers' Perceptions about Food Quality Attributes and Their Incidence in Argentinean Organic Choices AgEcon
Rodriguez, Elsa M.; Lupin, Beatriz; Lacaze, Maria Victoria.
There is an increasing consumers' concern for food safety and quality and, at the same time, there has been a significant market increment in differentiated or high value products consumption, including organic products. The lack of empirical research in Argentina regarding consumers' awareness of food safety brought our attention. Therefore, the objective of this paper is to analyse consumers' perceptions about the risk and quality attributes of food consumption; and to evaluate the incidence of these factors when buying organic products in Argentina. The Lancaster model (1966) provided the theoretical basis for the use of products attributes and characteristics to analyse the incidence of these attributes in consumers' choices. The data used in this...

Off-farm Income and Investments in Farm Assets: A Double Hurdle Approach AgEcon
Harris, James Michael; Blank, Steven C.; Erickson, Kenneth W.; Hallahan, Charles B..
The farm household structure is a complex set of inter-relationships between and among a variety of internal and external factors involving consumption, investment, and income-earning activities. In this paper we use ARMS data to explore the contribution of off-farm income to the viability of the farm business. We focus on the link between off-farm income and farm investment and whether off-farm income drives on-farm investment. The results indicate the importance of farm characteristics such as type, size, and location on the probability of investment but lead us to reject the hypothesis that off farm income is driving farm investment. Further research will be needed to further unweave some of the complex relationships involved in the farm household...

A Unified Approach to the Estimation of Demand for Improved Seed in Developing Agriculture AgEcon
Langyintuo, Augustine S.; Hamazakaza, Petan; Nawale, Edah; Mekuria, Mulugetta.
This paper proposes a new approach for estimating the demand for seed within a developing country context where only improved seeds are sold but adoption rates for improved varieties low. A farmer views an improved seed firstly as a derived input embodying production attributes and secondly, as a technology embodying consumption characteristics. He therefore jointly decides on its adoption and the quantity of seed required to plant a predetermined area. Drawing on the theory of demand for consumption goods characteristics and production input attributes, this paper specified and estimated non-separable household demand and consumption models using data collected from 300 farm households in Zambia during the 2003/04 crop season. The estimated results...

Willingness to Pay for Irradiated Meat Products: A Comparison between Poultry and Pork AgEcon
Huang, Chung L.; Wolfe, Kent; McKissick, John C..
Food processors are interested not only to increase the safety of their products but also to reduce losses associated with foodborne illness problems. Irradiating food products provides one means of addressing the foodborne illness issue by significantly reducing the presence of foodborne bacteria and diseases. The objective of the study is to develop an empirical model to estimate the likelihood of consumers purchasing irradiated food products and their willingness to pay for irradiated poultry and pork products within a two-step decision-making process. The decision-making framework assumes that consumers decide first whether or not to buy irradiated foods. If so, the consumer then decides specifically how much that they are willing to pay. Thus, a...

The economics of trade, biofuel, and the environment AgEcon
Hochman, Gal; Sexton, Steven E.; Zilberman, David.
The introduction of renewable biofuels was associated with global food crisis and unintended environmental consequences. This paper incorporates energy environment and agricultural sector to the classic Hecksher-Ohlin model to address these issues. A household production function model was introduced to model consumer energy choices and concern about externalities related to climate change and open space. The conceptual model links energy and food markets and derives guidelines for the development of climate change and land-use policies. The results suggest that globalization and capital flows increase demand for energy, leading to decline in food production, increase in food prices, and loss of environmental land. Globally optimal outcomes may require...

The contribution of female non-farm income to poverty reduction AgEcon
Seebens, Holger.
There is a widely held view that off-farm income in developing countries tends to reduce poverty, leading to the conclusion that policies should focus on the further diversification of income options of rural households. However, much off-farm employment might be initiated rather as a survival strategy but as a sustainable way to reduce poverty in the long run. Using a rich data set from Tanzania, this study examines the potential income increases generated by off-farm income with a particular focus on off-farm income contributed by women. The findings indicate that women’s contributions to household income through off-farm activities are limited and smaller as compared to those of men. Investigating the possible reasons, fetching water and collecting...

Trade, Food Standards and Poverty: The Case of High-Value Vegetable Exports from Senegal AgEcon
Maertens, Miet.
Agricultural supply chains are changing globally with pervasive food standards and increased vertical coordination. The impact of these changes for developing countries and for small farmers in those countries is not yet well understood. We analyze the developments in high-standards FFV supply chains and the effects for small farmers and rural households in Senegal. We use a unique dataset derived from company level interviews and household surveys in the main horticulture zone in Senegal. Supply chain restructuring resulted in a shift from contract-farming with small-scale producers to large-scale vertically integrated estate-farming. A comprehensive econometric analysis shows that the restructuring of the value chain has enhanced an equitable...

Fatter Attraction: Marital Status and the Relationship between BMI and Labor Supply AgEcon
Oreffice, Sonia; Quintana-Domeque, Climent.
We empirically analyze the labor supply choices of married men and women according to their body size (BMI), using data from the Panel Study of Income Dynamics on anthropometric characteristics of both spouses, and unmarried men and women as comparison group. Heavier husbands are found to work significantly more hours and earn more labor income, controlling for both spouses’ demographic and socioeconomic characteristics. Conversely, no such effect is found for either unmarried individuals or for married women. We suggest a marriage market mechanism through which male BMI and earnings are positively related. Heavier married men compensate for their negative physical trait by providing their wives with more disposable income, working more hours and earning...

Analysis of Value-Added Meat Product Choice Behaviour by Canadian Households AgEcon
Zhang, Xu; Goddard, Ellen W..
The competitive landscape in retailing has changed over the past decade. Moreover, the degree of product differentiation has been increasing: households are able to choose between an increasing number of store brands and national brands of similar products. The value added meat market is no different than any other sector of the grocery market – both national brands and private label brands are being developed to appeal to the consumer‘s desire for convenience, health, production and environmental attributes. Understanding the factors that are influencing consumers‘ value added meat product preferences is important for meat manufacturers who wish to add value to their firm‘s performance and increase market share. This knowledge is required in order to...

The Impact of Small Holder Commercialisation of Organic Crops on Food Consumption Patterns in KwaZulu-Natal, South Africa AgEcon
Hendriks, Sheryl L.; Msaki, Mark M..
The impact of smallholder commercialisation on food consumption patterns in a rural community of South Africa was investigated. The consumption patterns, dietary diversity and nutrient intakes of certified and partially certified members of an organic farmers' organisation were compared to data from a random sample of non-member households. Two consecutive survey rounds (n = 200) conducted in November 2004 and March 2005 enabled comparison of dietary diversity, nutrient adequacy (in terms of per household adult female equivalents for energy, iron, and vitamin A) and expenditure elasticities between seasons. Households with members engaged in certified comm ercial organic farming enjoyed greater dietary diversity, improved nutrient intakes com pared to...
