This study investigated the effect of information on the acceptability and purchase intention of an irradiated watercress salad and its non-irradiated counterpart among Brazilian consumers (N = 236). Both the irradiated and the non-irradiated products were fairly accepted (ratings about 6.0–7.0 in the hedonic scale). Significant effects (p ≤ 0.05) of gender, education, and age were also observed: acceptance and purchase intention was lower among male participants who received both information and an identified irradiated product, and higher among female participants who received only information about the process. Adults (30–39 years old) were more critical, and the higher the educational level, the lower the acceptability and purchase intention ratings. Brazil is one of the major irradiators in the world, but there is still a lack of consumer studies focusing the acceptability of irradiated foods. So the findings presented herein would favor Brazilian producers and regulators to develop effective communication strategies and to promote the irradiation technology.  相似文献

This research reveals connections between company strategies and consumer behavior patterns within the proposed method of developing a set of optimal strategies (a multi-component strategy) for a food company under the rapidly changing conditions intrinsic in the polycyclic business environment. This method is a strategic tool providing for efficient adaptation of a food company to current and potential environmental variability based on the polycyclic concept of environmental dynamics and on the suggested definition of strategy as a long-term interactive and proactive response to the influences of the business environment.  相似文献

We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed in both general linear-quadratic problems and in the underlying non-linear environments. A detailed example is provided using a canonical New Keynesian framework.  相似文献

In this article, we empirically investigate regional unemployment in Russia. We first detect the existence of two unemployment clubs, that is, regions with high (low) unemployment surrounded by regions with high (low) unemployment, and a group that comprises the remaining regions. We then apply a specially designed class of spatial-econometric models to regional data 2005–2012, using difference GMM, and we obtain partial confirmation of our two main hypotheses: (i) spatial effects for the high-high and low-low clubs regions differ significantly; and (ii) the determinants of unemployment of the two clubs significantly differ with respect to those of the remaining regions. Our results have key implications for the national- and regional-level policies.  相似文献

Russian external energy policy is frequently described as geopolitical (as opposed to EU energy policy, which is often characterised as market-based). This article reviews geopolitical and market approaches in existing studies and identifies paradigmatic and instrumental levels in each of them. It then proceeds to demonstrate that although the geopolitical paradigm dominates in Russia, Russia has also reacted to the EU’s third liberalisation package, using legal and technocratic instruments, which are parts of the market approach. Each set of instruments has its institutional basis in Russia: the President, the Ministry of Foreign Affairs (MFA) and Gazprom work in geopolitical ways but with frequent recourse to legal instruments, the Ministry of Economic Development (MED) promotes legal instruments and the Ministry of Energy (ME) is the centre of the technocratic activities, which Gazprom also frequently applies at present. This study therefore provides a more complex picture of Russian external energy policy. Moreover, it reveals a potential opening for a degree of policy convergence between the EU and Russia. In this context it is regrettable that legal and technocratic instruments were compromised as a result of the 2014 worsening in EU-Russian relations.  相似文献

This study evaluates a set of parametric and non-parametric value-at-risk (VaR) models that quantify the uncertainty in VaR estimates in form of a VaR distribution. We propose a new VaR approach based on Bayesian statistics in a GARCH volatility modeling environment. This Bayesian approach is compared with other parametric VaR methods (quasi-maximum likelihood and bootstrap resampling on the basis of GARCH models) as well as with non-parametric historical simulation approaches (classical and volatility adjusted). All these methods are evaluated based on the frequency of failures and the uncertainty in VaR estimates.Within the parametric methods, the Bayesian approach is better able to produce adequate VaR estimates, and results mostly in a smaller VaR variability. The non-parametric methods imply more uncertain 99%-VaR estimates, but show good performance with respect to 95%-VaRs.  相似文献

The valuation of STEM (science, technology, engineering, and math) firms has recently gained attention in the literature. Research has shown that, for valuation of STEM firms, accounting items such as sales growth and R&D expenditures matter more than bottom-line earnings. We examine whether, around the time of the IPO, STEM managers apply discretion over the accounting items most weighted by investors for their valuation. We find that investors tend to weigh sales growth and R&D more heavily than earnings in valuing STEM firms and that managers respond by managing those items rather than bottom-line earnings as in prior research. We find that future stock returns of STEM firms are negatively associated with sales management and not with abnormal accruals as for non-STEM firms. Our results illuminate the differential behavior of STEM managers and highlight the importance of a departure from the traditional IPO earnings management paradigm, which assumes that firms mainly manage their earnings.  相似文献

In this paper we present a macro-economic demographic growth modelhaving a special focus on social security. It is designed to study the variability of responses of the system in presence of risks and uncertainties. Here we analyze the robustness of the model towards uncertainties in parameterspecifications, introduced by ARCH-M models with the incorporation ofintervention processes. The parameters varied are labor force participationrates (one of the key sources of uncertainty in the social security policydebate), and the parameters of the production function (the key source ofuncertainty in any long-run economic analysis). The sensitivity analysisfocuses on two variables: assets of the private pension system and thebalance of the public `Pay As You Go' pension system. Special attentionis given to convergence properties of the macro-economic model.  相似文献

We examine the effects of changes in the income distribution in an economy where agents' utility depends both on consumption and on their rank in the distribution of conspicuous consumption. We introduce a new methodology to compare the behavior of agents that occupy the same rank in the two different income distributions but typically have different levels of incomes. Here, an increase in incomes of the least endowed improves their welfare, yet it also increases social competition, making those in the middle to be worse off—even if they have higher incomes as well. As social competition can be lowered by spreading agents apart in income space, we find that an increase in incomes for all, augmented by (weakly) increased income dispersion, constitutes a sufficient condition for Pareto-improvement. We also show that one can have an increase both in income and relative position but still be worse off.  相似文献

Consumer awareness about organic foods has been growing. However, this trend is not always translated to consumer organic food purchases. It is argued that when it comes to assessing organics, one should expect consumers to use multiattribute evaluations due to credence attributes and organic standards that organic foods need to adhere to. A thorough review of the existing literature on consumer buying behavior of organic foods identifies healthism, hedonism, and trust among some factors that enhance consumer experiences with organic foods and therefore can affect their purchase intentions. This article is one the few studies that integrated multiple factors in one research framework to empirically evaluate their role in explaining consumer purchase intentions of organic foods. Results from a demographically representative sample completed by an online survey in Australia (N = 1011) provides support for the research hypotheses by revealing positive and statistically significant effects of healthism, hedonism, and trust on consumer purchase intentions. The study concludes with implications and suggestions for future research.  相似文献
