Even though consumers’ status signaling is a heavily researched topic, empirical contributions from two important research areas—the mundane food context and prosocial status signaling between male consumers—to signaling literature are still scarce. Thus, this study empirically investigates how a male signaling about his status through favoring organic foods is perceived and treated by other males in two different sociocultural settings (urban vs. rural). In an urban area—but not in a rural—the pro‐organic signaler was perceived as more respected, altruistic, and affluent than a male who did not signal about this (he also received statistically more money in a charity donation task). This may indicate that signaling about this tendency—because it can be viewed as use of one's own resources for the benefit of others—is not only a way to attain status, but can also make others behave more positively toward the signaler.  相似文献

Empirical research using optimal hedge ratios usually suggests that producers should hedge much more than they do. In this study, a new theoretical model of hedging is derived. Optimal hedge and leverage ratios and their relationship with yield risk, price variability, basis risk, taxes, and financial risk are determined using alternative assumptions. The motivation to hedge is provided by progressive tax rates and cost of bankruptcy. An empirical example for a wheat and stocker‐steer producer is provided. Results show that there are many factors, often assumed away in the literature, that make farmers hedge little or not at all. Progressive tax rates provide an incentive for farmers to hedge in order to reduce their tax liabilities and increase their after‐tax income. Farmers will hedge when the cost of hedging is less than the benefits of hedging that come from reducing tax liabilities, liquidity costs, or bankruptcy costs. When tax‐loss carryback is allowed, hedging decreases as the amount of tax loss that can be carried back increases. Higher profitability makes benefits from futures trading negligible and hedging unattractive, since farmers move to higher income brackets with near constant marginal tax rates. Increasing basis risk or yield risk also reduce the incentive to hedge. © 2000 John Wiley & Sons, Inc. Jrl Fut Mark 20: 375–396, 2000  相似文献

Snack consumption encompasses the repetitive habits of consumers in various everyday life spaces. Despite the pervasiveness of snack consumption worldwide, the phenomenon of snacking has not been given extensive attention, unlike other areas of food consumption research. Yet, snacking shows certain distinctive features, such as fluidity of places. This study leans on foodscape literature and introduces the concept of snackscape, which enables us to showcase the multiplicity of places in snacking culture. While prior foodscape studies are located in certain tangible places, such as urban surroundings, festival sites or particular geographical areas, snackscapes demonstrate how snacks may be consumed, for instance, on the move from one place to another, or in a variety of places that are not part of one's ordinary routines, such as on a picnic or a holiday trip to a foreign country. The findings show how places of habitual snack consumption vary from time to time—or are even on the move. This is a powerful demonstration of how a routine‐like consumption practice takes place in everyday life. This study also highlights important consumer policy issues, especially in regard to young consumers and their snacking habits. Thereby, the study brings forward the agentic capacity of snackscapes having implications on engaging in healthier snack consumption.  相似文献

This study revisits the large but inconclusive body of research on crop yield distributions. Using competing techniques across 3,852 crop/county combinations we can reconcile some inconsistencies in previous studies. We examine linear, polynomial, and ARIMA trend models. Normality tests are undertaken, with an implementable R-test and multivariate testing to account for spatial correlation. Empirical results show limited support for stochastic trends in yields. Results also show that normality rejection rates depend on the trend specification. Corn Belt corn and soybeans yields are negatively skewed while they tend to become more normal as one moves away from the Corn Belt.  相似文献

This research investigates optimal price risk management strategies for fed cattle producers engaged in grid pricing. Stochastic simulation is used to determine optimal hedge ratios for fed cattle priced on a live weight basis or on a series of grids that vary in terms of premium/discount structure as well as base price. Results indicate that the optimal hedging strategy is greatly affected by the base price used in a particular grid. This has significant implications for pricing efficiency in the cattle market. Base prices that are linked more closely with downstream markets offer the potential to improve pricing efficiency; however, the risk associated with these prices is difficult to manage effectively with existing futures instruments.  相似文献

This study analyzes the relation of accessibility by road and railway network to population change between the years 1970-2007 in Finland. Accessibility is evaluated at built-up area unit and municipal levels by potential accessibility analysis and by measuring accessibility to network. Analyses are done in decadal periods by using geographical information systems (GIS) and data about road and railway networks involving digitized speed limits and geometry for each period. Accessibility variables and population change are related by generalized additive models (GAMs). The results indicate that the Finnish population has concentrated to areas with high road-based potential accessibility, especially since the opening in the Finnish economy in the 1990s. The accessibility of railway network was found to have affected the population change in the 1970s, when local level traffic reduced in the entire country, and in 2000-2007, following remarkable investments in long-haul transport.  相似文献

The common features of two interactive methods that can be used in multiple-party negotiations over continuous issues are studied. One method is based on finding jointly improving directions to the parties to move along and the other on making constraint proposals to the parties. The history and the related literature on the subject is briefly surveyed in order to position the methods within the field. The basic similarities and differences together with the possibility to use them jointly are studied from the point of view of single negotiation text concept. Potential application areas including facilitation agents in distributed artificial intelligence are suggested.  相似文献

Everyday traffic accounts for a significant share of overall greenhouse gas emissions, in particular carbon dioxide (CO2). While several solutions have been proposed for decreasing the emissions, a new kind of land use planning is required in order to achieve long-term effects. This study focuses on the effect of large retail store locations in the urban structure on overall CO2 emissions, by using the Oulu region, Finland, as a case study. The aim was to utilize GIS tools to assess store locations in terms of CO2 emissions from private cars used for consumer traffic. In this case, not only are the locations of the existing and planned retail units investigated with respect to population distribution and car ownership, but the analysis is also carried out by regarding any location within the study area as a hypothetical site for a large retail unit. According to the applied method, CO2 values are lowest near the centre of the studied region, the region with the highest population density, although the city centre itself did not turn out to be the most optimal location for a retail store in terms of CO2 emissions. Nevertheless, by generally reducing trip length, a compact urban structure is an important way of achieving long-term cuts in CO2 emissions.  相似文献

Global political and economic changes over the last decade have resulted into massive capital inflows to developing countries, most of these flows are foreign direct investments. In light of threats of political instability in the forms of civil wars, illegal capital flight, financial market instability, and political corruption, etc., further assessment of country risk is warranted. We examine the relationship between FDI and political and economic risks for 26 countries for the years 1992, 1993, and 1994 by using regression analysis and cross section data. The results indicate a significant relationship between FDI and these risks. This study provides more reliable estimates by using a current and eclectic measurement of risks represented by Euromoney indexes of political and economic risks. In the previous studies the perception of risk was narrowly defined and also political instability events were mistakenly interpreted as political risks.  相似文献

The aim of this paper is to provide an overview of alternative approaches in modeling consumer choice behavior with respect to making purchases either in the traditional manner or using an electronic shopping system. We concentrate on the effects of two specific features: the amount of time spent on shopping and the shopping experience. We consider a simple two-good situation in which one good is a composite good that consists of all goods purchased electronically, and the other is the composite of all goods purchased in a traditional manner. The models suggest that both time saved and an increase in shopping experience related to Web-based shopping will lead to increased purchasing at a Web shop.  相似文献
