Consumer Willingness-To-Pay for Different Organic Certification Logos in Turkey

Using data from focus group discussions with consumers and a choice experimentconducted in some of Turkey’s major cities, this study investigates whetherTurkish consumers prefer certain organic labelling schemes over others attemptsand to elicit their willingness to pay (WTP) for different organic certificationlogos. Although the level of awareness regarding organic certification logos waslow, consumers’ perceptions of the logos were generally positive. The results ofthe random parameter logit models indicated a positive WTP for the presence ofone of the three tested certification body logos in addition to the mandatorygovernmental logo. Given the low level of certification logo awareness, theconclusion is that both purchasing decisions and perceptions regarding logoswere affected by subjective criteria. Both the government and certification bodiesshould develop measures to increase consumer awareness of their logos and formconsumer perceptions and attitudes regarding the quality of the certificationimplied by the logo

Factors influencing the perception of organic certification logos in Turkey

Consumers’ perceptions on organic certification logos and the factors influencing these perceptions were explored. Data from surveys conducted in major cities of Turkey revealed that organic food consumers had little knowledge about logos, although the declared level of trust in organic logos was high. According to ordered logit models, consumer’s perceptions on organic certification logos were influenced by purchasing frequency and weight of organic foods in total food consumption. Dummy variables representing additional private certification company logos as well were generally found to have a significant effect on logo perception. This result suggests that consumers’ attitudes towards these logos and towards the governmental logo are not the same. Female and older people were more sceptical about the trustworthiness of the logos. While the credibility of the logos and the standards and control systems underlying the logos increased as frequency of purchasing organic food increased, those consumers who prefer organic open markets for buying organic food were hesitant to trust the credibility of the organic certification logos. The mandatory governmental logo and the underlying standards are trusted more than the private company logos. However, the difference of the attitudes toward logos decreases when the control system is in question. When a comparison between perceptions towards labels including different additional certification companies’ logos is made, the additional logo was found to affect the stated preferences more negatively when the companies were foreign. Enhanced interest and trust in the organic certification logos among consumers would foment the development of the organic sector, and the findings of this paper serve as an input for the achievement of this aim

Income and distance elasticities of values of travel time savings: New Swiss results

This paper presents the findings of a study looking into the valuation of travel time savings (VTTS) in Switzerland, across modes as well as across purpose groups. The study makes several departures from the usual practice in VTTS studies, with the main one being a direct representation of the income and distance elasticity of the VTTS measures. Here, important gains in model performance and significantly different results are obtained through this approach. Additionally, the analysis shows that the estimation of robust coefficients for congested car travel time is hampered by the low share of congested time in the overall travel time, and the use of an additional rate-of-congestion coefficient, in addition to a generic car travel time coefficient, is preferable. Finally, the analysis demonstrates that the population mean of the indicators calculated is quite different from the sample means and presents methods to calculate those, along with the associated variances. These variances are of great interest as they allow the generation of confidence intervals, which can be extremely useful in cost-benefit analyses

Measuring on Farm Diversity and Determinants of Barley Diversity in Tigray, Northern Ethiopia

Maintaining on-farm diversity of crop varieties has received increasing attention as a strategy for mitigating production risk and protecting food security in resource-poor farming systems with few opportunities for insurance or trade. Barley is grown under a wide range of environmental conditions and in marginal areas or seasons where the production of other cereals is limited. Food consumption preferences and variable tolerance to biotic and abiotic stresses influence the mixture and number of varieties to be grown. Phenotypic diversity was determined using Shannon diversity index. An econometric approach has been applied to identify the social and economic factors that influence levels of diversity maintained on-farm. A high phenotypic diversity index (0.79) was recorded from sampled barley varieties. Censored regression indicates that physical characteristics of the farm (land fragmentation index, farm size), agro climatic features of the site (altitude, rainfall, temperature) and household characteristics (only number of children) had a significant and positive impact on diversity and area allocation of barley. The significant negative relation of number of extension contact with barley diversity implies further attention and analysis. Key words: On farm diversity, Determinants of diversity, On farm conservation, Diversity inde

Impacts of community health insurance schemes on health care provision in rural Tanzania

In 1996 the Tanzanian government initiated community health insurance schemes to improve the access to health care and to protect people against the financial cost of illness in an environment with shrinking budgets for the health sector. This study aims to evaluate the role of the community health funds (CHF) in lowering the barriers to access health care. Three important results emerge from this study: First, the results show that income is amongst the most important factors determining household participation in the schemes. This means that despite exemption mechanisms, the poorest of the poor within the society are not reached as they can not afford to pay regular insurance premiums. Secondly, though we find no significant differences between members and non-members in the overall amount of health expenditure and in the use of preventive measures, sick individuals in member households were 15 percentage points more likely to get treatment than those in non-member households. Hence, being insured leads to an increase in the effective demand for health care. Third, the analysis reveals that members of the CHF are better financially protected against health shocks than non members. The result of this work provides further evidence of the important role that micro insurance schemes can play in the risk management of people in developing countries

Mismatch between soil nutrient requirements and fertilizer applications: Implications for yield responses in Ethiopia

Lack of accurate information about soil nutrient requirements coupled with limited access to appropriate fertilizers could lead to mismatch between soil nutrient requirements and fertilizer applications. Such anomalies and mismatches are likely to have important implications for agricultural productivity. In this paper we use experimental (spectral soil analysis) data from Ethiopia to examine farmers’ response to soil nutrient deficiencies and its implications for yield responses. We find that farmers’ response to macronutrient (nitrogen and phosphorus) deficiencies is not always consistent with agronomic recommendations. For instance, we find that farmers in our sample are applying nitrogen fertilizers to soils lacking phosphorus, potentially due to lack of information on soil nutrient deficiencies or lack of access to appropriate fertilizers in rural markets. On the other hand, farmers respond to perceivably poor-quality soils and acidic soils by applying higher amount of nitrogen and phosphorus fertilizers per unit of land. We further show that such mismatches between fertilizer applications and soil macronutrient requirements are potentially yield-reducing. Those farmers matching their soil nutrient requirements and fertilizer application are likely to enjoy additional yield gains and the vice versa. Marginal yield responses associated with nitrogen (phosphorus) application increases with soil nitrogen (phosphorus) deficiency. Similarly, we find that farmers’ response to acidic soils is not yield-enhancing. These findings suggest that such mismatches may explain heterogeneities in marginal returns to chemical fertilizers and the observed low adoption rates of chemical fertilizers in sub-Saharan Africa. As such, these findings have important implications for improving input management practices and fertilizer diffusion strategies
