Aggregate models of innovation diffusion do not capitalise on valuable consumer adoption dynamics that may be useful to policy makers and market planners. The non-diffusion choice literature shows quite clearly that these dynamics may indeed be very important factors in the diffusion process. The authors present a segmental broadband diffusion model that is estimated from consumer survey data that measure the effect that household income has on its propensity to adopt this technological product. The results suggest that early broadband adopters are mostly made up from wealthy households and only as time progresses do less well off households adopt. The findings presented in this paper will be important to market planners and policy makers requiring a relatively simple technique that forecasts segmental innovation diffusion.  相似文献

Food safety systems in emerging markets are currently facing a transformation period, becoming more stringent because of an increasing demand for safer food. Consequently, policy makers need to find strategies to increase food safety while giving the industry time to improve their performance. In Thailand, policy makers have adopted the strategy of upgrading food safety standards gradually. Government and private food safety brands and labels were introduced onto the market but little is known whether Thai consumers have preferences for them or not. This study is aimed at evaluating Thai consumers’ preferences for food safety labels and brands on fresh produce, using a surveyed based on discrete-choice experiments. A sample of 350 Thai consumers was surveyed in Bangkok and Nonthaburi in 2013. Quota sampling according to the shopping outlets and convenience sampling methods were adopted. Two hundred respondents were recruited at fresh-food markets and 150 respondents were recruited at supermarkets. We found that consumers are willing-to-pay more for both government led food safety label and private brands, but that there is high heterogeneity in their preferences. The high degree of social desirability for food safety labels confirms that food safety labelling policy should be supported. However, the provision of information and credibility are vital in order to mitigate the risk of consumer deception by self-claimed labels.  相似文献

Animal welfare is often cited as a classic public good, which implies market failure and, thus, that government intervention is required. However, the current literature does not provide an accessible account of how governed markets are supposed to cope with the issues of animal welfare. This paper seeks to fill this gap by re-considering the political economy of animal welfare. Conceptual analysis shows that the major cause of market failure in the case of farm animal welfare is a problem of consumption externalities. It is the specific regulation of animal welfare conditions which is a public good (or bad). Two important conclusions follow from this analysis, which are largely unexplored in the literature on animal welfare. First, measurement of potential market failure, through identifying actual willingness to pay (WTP) for animal welfare friendly products, is potentially misleading. The difference between citizen votes and consumer WTP for animal welfare is not prima facie evidence for either market failure or a gap in the market. Second, conventional arguments in favour of subsidies and assistance to producers for better animal welfare are misconceived and potentially counterproductive. A more rational policy is to subsidise the consumption of animal welfare friendly products.  相似文献

Food safety is one of the key issues for the international meat market. As a major meat exporter, few things facing the U.S. meat industry in recent years have garnered more attention than food safety events and policies. The impacts of Food Safety Inspection Services (FSIS) recalls on United States consumer meat demand are estimated using monthly grocery-scanner data identifying effects across products, geographic regions, and recall type. Results suggest beef E. coli recalls significantly reduce the demand for recalled ground beef contemporaneously among most, but not all, regions in the United States. Evidence of heterogeneity in demand impacts across regions and products is provided for the first time. Domestic and international implications for policy makers, industry leaders, and researchers are discussed.  相似文献

In the present paper we examine the effect of emissions permit price manipulation within an oligopolistic model. We examine the effect that positioning strategies in permits markets have on the degree of competition in the product market as well as on social welfare. The analysis is based on the concept of raising rivals' cost strategies. We find that competition in the product market can be lessened substantially. The welfare effect is ambiguous. If the leader expands its market share at the expense of a less efficient rival, or if it excludes a less efficient entrant, overall efficiency may increase despite the decrease in the industry's output. When efficiency decreases, or when consumers' protection is a policy priority, the initial distribution of permits can be used to control power in the permits market. Such interventions though, improve efficiency only when policy makers have substantial information on the technological structure of the industry, and thus, should be used with caution. Given the importance of information, sharing of information and coordination of actions between policy makers is very important.  相似文献

Consumer willingness-to-pay for informational attributes of food products is important information for food producers and supply chain participants and policy makers. We examine consumer demand in the pork sector of the Republic of Georgia. Results of conditional and mixed logit estimation, conducted on choice experiment data, reveal that Georgian consumers treat quality certification and product traceability attributes as substitutes. We also find that producers and other supply chain participants should be concerned primarily with maintaining the appearance of pork products. Retailer specific factors such as location and type of outlet can also substitute for product traceability. Store location and product appearance, however, are complementary attributes. In light of the recent turbulence in Georgia these consideration may be of paramount importance as participants in the supply chain seek to rebuild damaged infrastructure.  相似文献

This paper takes as a starting point the proposition that social protection interventions involving food can be used to promote transformational change in family farming systems in sub-Saharan Africa. The purpose is to highlight the complexity of pathways to agricultural transformation associated with the seemingly simple idea of home-grown school feeding (HGSF), an idea that is increasingly held up as “win–win”. By reviewing the HGSF literature and the main theories underpinning it – structured demand, localism, family farmer development – we expose areas of inconsistency across the literature and programmes as well as possible tensions that may arise in attempting to pursue both market and social objectives in the same initiative. The arguments presented herein aim to provide a basis for moving towards clarity on (1) a theory of change for HGSF programmes; (2) the conditions under which HGSF programmes are more able to yield positive agricultural development outcomes and; (3) an agenda for moving forward on research and impact evaluation. This research agenda also speaks more broadly to important under-researched areas within the general social protection and agricultural development discourse.  相似文献

Given heavy dependence on rainfed maize production, countries in East and Southern Africa must routinely cope with pronounced production and consumption volatility in their primary food staple. Typical policy responses include increased food aid flows, government commercial imports and stock releases, and tight controls on private sector trade. This paper examines recent evidence from Zambia, using a simple economic model to assess the likely impact of maize production shocks on the domestic maize price and on staple food consumption under alternative policy regimes. In addition to an array of public policy instruments, the analysis evaluates the impact of two key private sector responses in moderating food consumption volatility – private cross-border maize trade and consumer substitution of an alternate food staple (cassava) for maize. The analysis suggests that, given a favorable policy environment, private imports and increased cassava consumption together could fill roughly two-thirds of the maize consumption shortfall facing vulnerable households during drought years.  相似文献

The state government of Victoria, Australia, recently prepared a discussion paper towards a regional food and nutrition policy. This evaluation finds it deficient in various ways. The critique contains recommendations for the building of a national food policy. The commission report displays a lack of a systems view of the problem of nutrition, which would recognize a diversity of influences on eating (e.g. social frameworks and frameworks by which we think and know). Linear causality is not an adequate concept. Agribusiness impacts heavily on the environment. In the case of meat production, inputs to production far exceed food energy outputs. Disposal of the by-products of meat production is also more problematic. The way to impact on these wasteful and destructive industrial practices is to consume less meat. Additives in food are a serious problem not well enough addressed. This and other processing increase the cultural perception of foodstuffs as human artifacts. Awareness of the cultural role of foods would allow Australians to cope with industry campaigns promoting meat and processed foodstuffs. There should be more attention to mutual impacts of environment, consumptiuon, and additives and processing. Food from low in the food chain (cereals, seafood) should be promoted not as substitutes but as foods in their own right. Commission recommendations should deal with questions such as nutritional information labeling of foods, and especially an attempt to foster consciousness of the environmental impact of food consumption: Government policy should be mindful to the extent possible of the impact on poor areas of the world of wasteful food consumption in Australia. Proposals for action should benefit from the impact of several fields of expertise beyond health, agriculture, consumer affairs and others; for instance, anthropology or environmental science.  相似文献

This study investigates the food consumption patterns of different income classes in urban areas of Mali in order to assess the probable effects on dietary adequacy of the expected increase in the consumer price of rice brought about by food policy reform, initiated in 1981. The results are to a degree counterintuitive, demonstrating that understanding consumption patterns and their determinants is critical to informed policy making.  相似文献

One of the most complex policy issues facing many developing-country governments over the next decade, particularly in sub-Saharan Africa, concerns the problem of providing the impoverished sections of urban populations with adequate food at prices they can afford, while both meeting the fiscal requirements of adjustment programmes and promoting domestic agricultural production. The pressure to reduce urban food subsidies is in many cases already immense, and the implications for urban household food security are considerable. This article looks at recent Zambian experience, and suggests that new and more efficient ways of targeting subsidies may be required if levels of food consumption are not to deteriorate still further.  相似文献

This paper takes a local perspective on global food price shocks by analyzing food price transmission between regional markets in Ghana. It also assesses the impacts of food price increases on various household groups. Taking the 2007–2008 global food crisis as an example, we show that prices for domestic grain products are highly correlated with world market prices. This is true both for products for which Ghana is highly import-dependent (e.g., rice) and the products for which Ghana is self-sufficient (e.g., maize). The econometric results also show that price transmission is high between regional producer markets and markets located in the country’s largest cities, and the distance between producer and consumer markets and the size of consumer markets matter in explaining the price transmission. The welfare analysis for households as consumers shows that the effect of world food prices appears relatively modest for the country as a whole due to relatively diverse consumption patterns within country. However, the national average hides important regional differences, both between regions and within different income groups. We find that the poorest of the poor—particularly those living in the urban areas—are hardest hit by high food prices. The negative effect of the food crisis is particularly strong in northern Ghana. The main explanations for this regional variation in the price effect is the different consumption patterns and much lower per capita income levels in the North of Ghana compared to other regions in the country.  相似文献

The impact of changes in food labeling policy on food consumption depends on how market participants—both firms and consumers—react to the changes across all products in the market. We investigate how both responded to the U.S. Food and Drug Administration’s 2006 rule mandating that the quantity of trans fat in food products be separately labeled on the mandatory Nutrition Facts Panel across an entire differentiated product category. Using a longitudinal data set tracking both product offerings and consumer purchases in the market for margarine and spreads for over a decade, we analyze how product mix and consumer purchase behaviors were influenced by the new regulatory requirement. We find that the number of products bearing voluntary “trans fat free” labels increased after the labeling regulation was implemented. However, a large number of the newly introduced products exited the market within five years. As a result, the FDA’s 2006 rule had a stronger short-run than long-run effect on product offerings. Even after the introduction of additional “trans fat free” labeled products, such products remained only a small percentage of margarine and spreads product offerings, increasing from a pre-regulation level of 2.3% of the market to a peak of 6.5% in 2007 before dropping to 3.1% by 2011. In addition to firm response, we examine demand-side reactions to the 2006 rule and find that consumers significantly increased their expenditures on “trans fat free” labeled products soon after the labeling changes were implemented, increasing from about 1.2% of the market in 2001 to a peak of 5.9% in 2007, before returning to 1.8% in 2011. We further explore variations in responses across different demographic characteristics. Although long-run effects are small, the market for “trans fat free” labeled margarine and spreads settled into a new equilibrium with a somewhat higher level of products in the market than prior to the 2006 rule taking effect and a somewhat higher share of expenditures in the category. Overall, our category-wide analysis of both firm and consumer behavior indicates that the effects of the labeling policy change were smaller in the longer run in this market than would be indicated by an analysis of only new product introductions in response to the policy change.  相似文献

This paper examines the impact of health information in different media outlets on bottled water consumption through consumer learning. We develop a random coefficient discrete choice model with Bayesian learning process to capture consumers’ learning of health information and changes in their beverage choices over time. Consumers are assumed to have initial prior beliefs about the health effect of different beverages and to update their beliefs using health information received from different media types. Empirical results show that consumers’ perceived quality of bottled water kept increasing during our sample period, and this learning process accounted for 24.44% of the industry’s revenue, which is about 4.8 billion dollars per year. Comparing the effectiveness of different media outlets, we find that the sales impact of traditional media (TV and radio) is greater than online sources. Our findings highlight the contribution of health information to the bottled water industry and provide policy makers with a new direction to reduce high-calorie food consumption and improve public health.  相似文献

Significant growth in mobile media consumption has prompted a call to better understand the socio-cultural and policy dimensions of consumer choices. Contrary to industry and technology led analysis, this study argues that to guide consumer choice and innovation via regulatory policies requires an understanding of both ex-ante as well as in ex-post consumption conditions. This study examines mobile phone gaming to uncover how consumer anti-choice shapes decision-making as a framework for closely interrogating the ways in which policy concerns impact on consumers’ behavior. Through eleven focus groups (n=62), the study empirically identifies voluntary, intentional, and positive consumer anti-choice behaviors all of which impact policy initiatives when consumers, both gamers and non-gamers, self-regulate their behaviors. Findings point to four types of policy implication: regulating the self-regulated, understanding anti-choice, boundary-setting and including the self-excluded.  相似文献

We investigate how the provision of objective information about the environmental and health impact of organic labels by policy makers can influence the willingness-to-pay of consumers for labeled organic apples in Flanders (Belgium). Using a stated choice experiment, we initially find that Flemish consumers are willing to pay a positive price premium of some 33 eurocent per kilogram for labeled organic apples. After the provision of information on the actual environmental and health effects of organic apple production, this price premium becomes even more pronounced and increases to 57 eurocent per kilogram. Using a conditional logit model with covariates and a mixed logit model, we find evidence of preference heterogeneity. Also, the effect of information provision is more pronounced for certain groups of consumers such as non-vegetarians, infrequent buyers of organic products and members of a nature protection organization. As such, this paper illustrates that there is a role for policy makers and CSR producers in providing more accurate and reliable information about socially responsible production processes. Moreover, it is important to take the observed preference heterogeneity into account and tailor policies to specific consumer groups.  相似文献

Indigenous chicken serves many functions, which include the provision of meat and eggs for home consumption and income from sales. The purpose of this study was to estimate the consumers’ responsiveness to an increase in prices of the indigenous chicken products and how much they are willing to pay for them in the market. The survey was conducted in the selected three regions of Kenya. A total of 930 respondents were interviewed both in the urban and rural areas. Contingent valuation experiment was used in empirical data collection. The two-step Heckman selection model was utilised to analyse consumers decisions and the amount they were willing to pay. The study results revealed that consumers are willing to pay 23.26% per kg more for indigenous chicken meat and 41.53% for eggs. Socioeconomic factors like age, income, education and family size significantly determines consumers’ willingness to pay. Other important factors include the indigenous chicken meat substitutes’ prices, attributes like taste/flavour and the product’s form on purchase. The yolk colour and size of eggs determined the consumers’ willingness to pay. Preferences for indigenous chicken products were found to be high. This information will assist in understanding both the urban and rural consumer’s behaviour. Therefore, useful for the indigenous chicken producers, breeders, marketers and policy makers in developing efficient production and marketing strategies. This would also provide a means of improving food security and livelihoods of the rural poor indigenous chicken farmers.  相似文献
