Realistically, organizational and/or system performance is dynamic and non-linear. However, in the efficiency literature, system performance is frequently evaluated considering linear combinations of the input/output variables and without explicitly taking into account the causes of efficiency behavior nor the dynamic behavior of systems. Policy decisions based on these results may be sub-optimized because the non-linear relationships among variables, causal relationships, and feedback mechanisms are ignored.This research takes the initial step of evaluating system performance in a dynamic environment, by relating the factors that effect system performance to the policies that govern it. To accomplish this, this paper extends the concepts of the static production axioms into a dynamic realm, where inputs are not instantaneously converted into outputs. The relationships of these new dynamic production axioms to the basic behaviors associated with system dynamics structures are explored. 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

Firms that follow excessive payout policies (over-payers) are higher on the financial distress spectrum and have lower survival rates than under-payers. In addition, over-payers endure lower future sales and asset growth than under-payers and experience negative abnormal returns in the bond and stock markets. Exogenous import tariff reductions and commodity price jumps reduce the likelihood of overpayment. We interpret this as evidence consistent with financial flexibility considerations, rather than risk-shifting, explaining the decision to overpay. We also find that CEO overconfidence and catering incentives affect overpayment. 相似文献

This paper uses a micro-founded DSGE model to compare second-best optimal environmental policy, and the resulting Ramsey allocation, to first-best allocation. The focus is on the source and size of uncertainty, and how this affects optimal choices and the comparison between second- and first-best. While higher economic volatility is bad for social welfare in all cases studied, the welfare effects of higher environmental volatility depend on its size and the effectiveness of public abatement policy. The Ramsey environmental tax is pro-cyclical when there is an economic shock, while it is counter-cyclical when there is an environmental shock. 相似文献

Air travel is, nowadays, recognized as being one of the most popular modes of transport. Air transport is among the most significant contributors to the world gross domestic product and is accountable for a great environmental and social impact. Driven by the well‐established sustainability discourse and the vital role businesses can play in disseminating the sustainable development concept, this paper attempted to map airport industry's most material operational aspects and assess airport operators' accountability level on disclosing corporate information regarding airports' economic, environmental, and social performance. In this context, 33 reports and 903 material issues representing 193 international airports were reviewed and assessed, and a methodology for benchmarking the accountability level of best reporting airport operators was developed, showcasing materiality assessment as a useful management tool for strengthening airport operators' business strategy and enhancing their corporate performance. The paper indicated that (a) customer focus (i.e., health, safety and satisfaction), economic viability, and business continuity and preparedness are operational aspects of high materiality and (b) the disclosure level, especially concerning specific performance indicators, is still moderate. In conclusion, this study has shown that materiality assessment gains ground as a management tool among airports' management teams and the completeness of Sustainability reports is positively correlated with the “level” of adherence as described by the Global Reporting Initiative. 相似文献

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

Differences between bank employees' perceptions towards implications of electronic banking in Greece
Konstantinos Lymberopoulos Ioannis E Chaniotakis 《Journal of Financial Services Marketing》2003,8(1):35-47
This paper aims to identify both the Greek branch and the central division employees' perceptions towards implications of electronic banking adoption and explore whether there are any differences between them. To this end, based on 14 potential implications recognised in the literature review, a questionnaire was designed and completed by 613 bank employees. The analysis showed that perceptions vary in relation to respondents' working position. Additionally, there are indications that the identified differences are greater if they are linked with the respondents' working experience and educational qualifications, as well as the size of the financial institution. In conclusion, the paper discusses the strategic implications of the findings. 相似文献

Regional Integration and Economic Growth 总被引:4,自引:0,他引:4
The rapid economic growth of developing countries that openedtheir markets to free international trade during the past twodecades has stimulated a large empirical and theoretical literatureon the impact of trade on growth. This literature concludesthat free trade and growth were positively correlated duringthe 1970s and 1980s. However, most studies focus on nondiscriminatoryopenness. Does regional integration matter for economic growth?Do regional trade agreements have any impact on growth? This article presents empirical evidence that countries withopen, large, and more developed neighboring economies grow fasterthan those with closed, smaller, and less developed neighboringeconomies. The results are robust to different specificationsof the empirical model and different definitions of openness,suggesting that small economies should grow faster when theyform regional trade agreements with large and more developedeconomies. However, testing for the impact of five regionaltrade agreements during the 1970s and 1980s finds that noneled to faster growth. The main reason seems to be that mostof these agreements were among small, closed, and developingeconomies. 相似文献

This paper studies the relationship between audit and non-audit service fees paid to the statutory auditor by UK life insurance firms, utilising an extensive panel-data sample set for the period 1999–2009. Consistent with a knowledge spillover (impairment of independence) hypothesis, we predict and find that audit fees are positively (negatively) associated with actuarial (tax service) fees. Additionally, our results indicate that regulatory changes enforced after 2004 deterred UK life insurance firms from purchasing non-audit services that are perceived to impair auditor independence. Finally, we find evidence concerning the inter-temporal determination of audit fees. 相似文献
