This paper presents a study of financial surrogate usage among adult consumers. A scale to discriminate between heavy users and non-users the Desire for Financial Surrogacy Scale (DFSS) is developed and tested in a mail survey. Financial surrogacy usage is found significantly associated with biological sex, income, degree of financial opinion leadership, but not significantly associated with need for financial control, anxiety about money management, and risk-aversiveness. The DFSS is found to be the best discriminator between user groups. Marketing implicatiom of increased knowledge of who heavy users are and what they want are discussed in reference to new consumer segments, product innovation, and promotion. 相似文献

This article provides an empirical analysis of the impact of European Union (EU) private food safety standards on pesticide use and farm‐level productivity among small‐scale vegetable producers in Kenya. We apply an extended three‐stage damage control production framework, accounting for multiple endogeneity problems, to farm‐level data collected from a random cross‐sectional sample of 539 small‐scale producers. Estimation results show that farmers producing vegetables for the domestic market use significantly lower quantities of pesticides than do export farmers. However, contrary to findings elsewhere, the econometric evidence here shows that both domestic and export‐oriented vegetable farmers in Kenya use pesticides at levels below the economic optimum. The results also show that the adoption of standards by export farmers does not have any significant impact on total pesticide use. However, adopter categories are distinguishable in terms of types of pesticide used, i.e. adopters use safer pesticides based on World Health Organization (WHO) classification. The third‐stage structural revenue model results demonstrate that adoption of standards has a positive and significant impact on revenue raised in vegetable production. Nevertheless, farmers producing for the export market are indistinguishable from those producing for the domestic farmers in terms of the total revenue earned from producing vegetables during the rainy season, on a ‘per acre’ basis. Although standards can potentially prevent resource‐poor smallholders from maintaining their position in the lucrative export markets, they can also result in positive changes in the production systems of those small‐scale farmers who adopt it, as shown by these results. 相似文献

This article investigates the post-announcement drift (PAD) of stock returns in the Chinese stock market. We use a sample of voluntary trading disclosures to test the hypothesis that an asymmetric PAD exists in a market in which managers are more likely to suppress negative news. We show that a pattern of short-term momentum and long-term reversal in returns persists for up to 250 trading days following the announcement of trading statements in the Chinese stock market. This finding is stronger for positive announcements in terms of the magnitude and the variance of stock returns. Our findings are in line with both Shin’s theoretical predictions and the credibility hypothesis, in which disclosure and asset returns are jointly determined and the adoption of a “sanitisation strategy” in information disclosure generates more volatile returns for firms issuing good news. Further, we show that the latter effect is more pronounced for firms which are partially state-owned, suggesting that they potentially receive more government support, a finding which is in line with the hypothesis that the incentive to suppress negative information is related to a country’s legal/judicial system. 相似文献

Technological activity, taken in a broad craft sense, is not new to primary schools. What is new is its organisation as a serious curriculum subject in which pupils are expected to make valuable progress. Arguing about technology-as-education must include some understanding of what it can offer of wide value to successful students. Unfortunately those who have carried out empirical research in the field of primary technology have been unable to specify what such valuable progression might look like. There are just two rather limited sources of information relevant to development and progress in technology — cognitive psychology and teacher action research. Neither of these is easy to use as they stand because they are either unconnected with the act of teaching, or on a very small and personal scale. However this paper argues that, taken together, they are beginning to show that teaching has valuable and specific tasks to carry out, which can help pupils make recognisable progress in primary technology. 相似文献

This paper presents a case study of the emergence of currency from a barter economy in an online game community. We use this case study to attempt to shed light on the relative importance of various types of frictions that lead to the emergence of money in search-theoretic models of currency formation. In particular, our study highlights the importance of exchange frictions relative to epistemic frictions. Using the records of an online message board dedicated to facilitating trades within the game, we document the emergence of currency and its stability over time. 相似文献

Hypothetical bias is tested based on inter- and intra-respondent comparisons of choice behavior, applying a hypothetical and real choice experiment. The inter-respondent comparison commonly applied in the environmental and agricultural economics literature consists of a control group of buyers who are asked to hypothetically choose between conventional and organic beans and an experimental group of buyers who are endowed to purchase the same beans using an identical experimental design. Hypothetical bias is tested by comparing inter- and intra-respondents’ (i) hypothetical and real choices, (ii) preference parameters of the estimated choice models related to hypothetical and real choices, and (iii) hypothetical and real willingness to pay (WTP). Choices in the experimental group are highly consistent when switching from hypothetical to real choices for this study's homegrown goods. However, after being endowed, the price sensitivity of lower income households drops, suggesting a house money effect. WTP derived from actual purchases is higher than WTP based on hypothetical choices, indicating a negative hypothetical bias, but differences are only significant in the case of the inter-respondent comparison. Actual prices paid by respondents in the field experiment appear to be considerably lower than the estimated WTP values and yield a mixed picture of hypothetical bias. 相似文献

This article examines the driving forces behind farmers’ decisions to adopt improved pigeonpea and maize and estimates the causal impact of technology adoption on household welfare using data obtained from a random cross‐section sample of 613 small‐scale farmers in Tanzania. We use seemingly unrelated and recursive bivariate probit regressions to test the endogeneity and joint decision making of pigeonpea–maize production. A double hurdle model is used to analyze the determinants of the intensity of technology adoption conditional on overcoming seed access constraints. To address the impact of adoption on welfare, the article employs both propensity score matching and switching regression techniques. Results from bivariate probit models show that unobservable factors cause both decisions to be correlated but the finding does not support the conjecture that both decisions are made jointly. Overall the analysis of the determinants of adoption identifies inadequate local supply of seed, access to information, human capital, and access to private productive asset as key constraints for pigeonpea technology adoption. The causal impact estimation from both the propensity score matching and switching regression suggests that maize/pigeonpea adoption has a positive and significant impact on income and consumption expenditure among sample households. 相似文献
