Environmental issues are massively emerging in the current agendas of governments, businesses and consumers all over the globe. Consumers increasingly adopt a more energetic role in the environmental discussion and employ product consumption to manifest their contribution to the debate. Equally, a growing number of businesses try to affect positive social change, whereas others strategically approach green opportunities; at the same time, they persistently intensify their branding offerings to sustain loyalty. This article brings into discussion green consumption values as the authors aim to shed light into the way the latter moderate the effect of brand related factors, namely, brand experiences and brand personality, on brand loyalty. Based on data received from 413 participants and using the wearable technologies industry as the focal context, the study underscores the significance of green consumption values. Findings are discussed, and implications for managers are provided. 相似文献

We perform an empirical investigation of the macroeconomic consequences of international terrorism and interactions with alternative forms of collective violence. Our analysis is based on a rich unbalanced panel data set with annual observations on 177 countries from 1968 to 2000, which brings together information from the Penn World Table data set, the ITERATE data set for terrorist events, and data sets of external and internal conflict. We explore these data with cross-sectional and panel growth regression analysis and a structural VAR model. We find that, on average, the incidence of terrorism may have an economically significant negative effect on growth, albeit one that is considerably smaller and less persistent than that associated with either external wars or internal conflict. As well, terrorism is associated with a redirection of economic activity away from investment spending and towards government spending. However, our investigation also suggests important differences both regarding the incidence and the economic consequences of terrorism among different sets of countries. In OECD economies, in particular, terrorist incidents are considerably more frequent than in other nations, but the negative influence of these incidents on growth is smaller. 相似文献

In the probabilistic risk aversion approach, risks are presumed as random variables with known probability distributions. However, in some practical cases, for example, due to the absence of historical data, the inherent uncertain characteristic of risks or different subject judgements from the decision-makers, risks may be hard or not appropriate to be estimated with probability distributions. Therefore, the traditional probabilistic risk aversion theory is ineffective. Thus, in order to deal with these cases, we suggest measuring these kinds of risks as fuzzy variables, and accordingly to present an alternative risk aversion approach by employing credibility theory. In the present paper, first, the definition of credibilistic risk premium proposed by Georgescu and Kinnunen [Fuzzy Inf. Eng., 2013, 5, 399–416] is revised by taking the initial wealth into consideration, and then a general method to compute the credibilistic risk premium is provided. Secondly, regarding the risks represented with the commonly used LR fuzzy intervals, a simple calculation formula of the local credibilistic risk premium is put forward. Finally, in a global sense, several equivalent propositions for comparative risk aversion under the credibility measurement are provided. Illustrated examples are presented to show the applicability of the theoretical findings. 相似文献

We review a rich class of point process models, Cox point processes, and illustrate the necessity of more than one observation (point patterns) in performing parameter estimation. Furthermore, we introduce a new Cox point process model by treating the intensity function of the underlying Poisson point process as a random mixture of normal components. The behaviour and performance of the new model are compared with those of popular Cox point process models. The new model is exemplified with an application that involves a single point pattern corresponding to earthquake events in California, USA. 相似文献

This study investigates consumer response to food labels in an emerging market. More specifically, it measures the levels of awareness, objective and perceived understanding, perceived usefulness and perceived trustworthiness of the most prominent food labels found in the Romanian market. An online survey was conducted with a convenience sample of 428 respondents (45.6% males of an average age of 30.6 years). Results revealed that for most respondents, awareness levels towards food labels are generally low, except for the Guideline Daily Amount (GDA) and the organic food labels. Objective understanding towards food labels was relatively high, especially towards those food labels that included a clear text element. Perceived understanding, perceived usefulness and perceived trustworthiness were found to be consistently high with regard to the GDA and the national organic food labels, while the European organic label scored lower. Finally, response to food labels was found to differ between aware and unaware respondents. 相似文献

We analyze a two-attribute single item procurement auction that uses yardstick competition to settle prices. The auction simplifies the procurement process by reducing the principal’s articulation of preferences to simply choosing the most preferred offer as if it was a market with posted prices. This is done simply by replacing the submitted sealed bids by yardstick bids, computed by a linear weighting of the other participants’ bids. We show that there is only one type of Nash equilibria where some agents may win the auction by submitting a zero price-bid. Using a simulation study we demonstrate that following this type of equilibrium behavior often leads to winner’s curse. The simulations show that in auctions with more than 12 participants the chance of facing winner’s curse is around 95 %. Truthful reporting, on the other hand, does not constitute a Nash equilibrium but it is ex post individually rational. Using a simulation study we demonstrate that truthful bidding may indeed represent some kind of focal point. 相似文献

In this study, we attempt to examine the possibility of emergence of significant fluctuations of the exchange rates in the
future for the candidate EMU countries. In doing so, we estimate the equilibrium rate of the nominal effective exchange rate
for Poland, Hungary, Slovak Republic and Malta through the BEER and PEER approaches. While the PEER-based estimation implies
a large misalignment rate for the Hungarian forint, the BEER-based analysis shows that the present exchange rates of the countries
considered do not deviate significantly from their equilibrium rates. As a consequence, based on BEER analysis, we do not
expect large fluctuations in the effective exchange rates among the currencies considered. Hence, the relevant effective exchange
rates are expected to be relatively stable. As a matter of fact, the entry of those countries into EMU is not expected to
weaken the stability of Euro.

Consumers worldwide are increasingly concerned with sustainable production and consumption. Recently, a comprehensive study ranked 17 countries in regard to their environmentally friendly behaviour among consumers. Brazil was one of the top countries in the list. Yet, several studies highlight significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour: the so‐called ‘Attitude‐Behaviour Gap’. In developing countries, few studies have been conducted on this issue. The objective of this study is therefore to investigate the gap between citizens' sustainability‐related attitudes and food purchasing behaviour using empirical data from Brazil. To this end, Brazilian citizens' attitudes towards pig production systems were mapped through conjoint analysis and their coexistence with relevant pork product‐related purchasing behaviour of consumers was investigated through cluster analysis. The conjoint experiment was carried out with empirical data collected from 475 respondents surveyed in the South and Center‐West regions of Brazil. The results of the conjoint analysis were used for a subsequent cluster analysis in order to identify clusters of Brazilian citizens with diversified attitudes towards pig production systems, using socio‐demographics, attitudes towards sustainability‐related themes that are expected to influence the way they evaluate pig production systems, and consumption frequency of various pork products as clusters' background information. Three clusters were identified as ‘indifferent’, ‘environmental conscious’ and ‘sustainability‐oriented’ citizens. Although attitudes towards environment and nature had indeed an influence on citizens' specific attitudes towards pig farming at the cluster level, the relationship between ‘citizenship’ and consumption behaviour was found to be weak. This finding is similar to previous research conducted with European consumers: what people (in their role of citizens) think about pig production systems does not appear to significantly influence their pork consumption choices. Improvements in the integrated management of this chain would better meet consumers' sustainability‐related expectations towards pig production systems. 相似文献

In the emergence of ethically conscious consumer segments across Europe, the expectation was that foods with a designation of origin–label (DOL) would make a production system of similar logic. Past analysis of the registration history of DOLs showed that the take-up of this European Union (EU) food quality scheme was concentrated in the south, which was attributed to specific food supply-and-demand conditions prevalent in that part of Europe. The authors shed light on DOL product distribution and examine its evolution during a 14-year period (2001–2014). DOLs remain a quality differentiation scheme predominantly for the southern EU agrifood industry. However, the less restrictive requirements for protected geographical indication certification make it a much more popular DOL in northern EU. To promote its food quality policy, the EU must approach the two DOL types differently, as they have a different growth potential among EU countries. DOLs’ specialization in categories with expertise accumulated in specific EU areas can become a DOL promoter across all of Europe. 相似文献

This paper investigates the effects of discretionary fiscal policy changes on economic activity and its subcomponents in Greece in the period 2000–2011. Changes in government spending and net taxes have Keynesian effects. An increase in government consumption has the most pronounced positive effects on output growth, private consumption and non-residential investment, while it reduces residential investment. Cuts in the public investment programme crowd in private investment, but are associated negatively with the net exports ratio. Both indirect and direct tax hikes lower private consumption, private investment and output growth. However, higher direct taxes by lowering disposable income they reduce import demand, thus, improving the trade balance. 相似文献
