Rational expectations are often used as an argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances rational expectations can enhance our power to control an economy over time. In those cases, policy announcements can be used to extend the impact of conventional policy instruments. We present a general forward-looking policy framework and use it to provide a formal rationale for testing when policymakers can and cannot expect to be able to manage expectations. To describe the relevance of our results applications are shown for policy design in small-open economies. Those are the cases where domestic policies are at their weakest and our ability to influence expectations most constrained.  相似文献

This paper discusses, estimates and formally compares the best known procedures for incorporating demographic variables into complete demand systems. In particular, a class of general procedures belonging to Gorman's family of ‘general linear household technologies’ is introduced. Estimation and comparison of different procedures make use of Italian household budget data for the years 1973–1992, incorporating a single demographic variable (family size) into a Generalized Quadratic Almost Ideal Demand System. In our empirical example, however, even the most general household technologies are unable to fully capture the behavioural heterogeneity shown by the data.

This paper reports the findings of two experimental investigations into the efficacy of a causal cognitive mapping procedure as a means for overcoming cognitive biases arising from the framing of strategic decision problems. In Study 1, final year management studies undergraduate students were presented with an elaborated strategic decision scenario, under one of four experimental conditions: positively vs. negatively framed decision scenarios, with prechoice vs. postchoice mapping task orders (i.e., participants were required to engage in cognitive mapping before or after making a decision). As predicted, participants in the postchoice mapping conditions succumbed to the framing bias whereas those in the prechoice mapping conditions did not. Study 2 replicated and extended these findings in a field setting, on a sample of senior managers, using a decision scenario that closely mirrored a strategic dilemma currently facing their organization. Taken together, the findings of these studies indicate that the framing bias is likely to be an important factor in strategic decision making, and suggest that cognitive mapping provides an effective means of limiting the damage accruing from this bias.

By referring to research on the measurement of the Big Five personality factors, this article investigates measurement characteristics of brand personality (BP) dimensions. The authors apply a meta‐analysis and investigate the intercorrelations and reliabilities of the BP dimensions of Sincerity, Excitement, Competence, Sophistication, and Ruggedness, as suggested by Aaker (1997). Similar to the Big Five personality factors, the measurement of BP reveals interdependence of the dimensions and one General Personality Factor. Furthermore, the reliabilities reveal instability across method characteristics, for instance, the use of facets as opposed to traits in measuring BP drives up the reliabilities of those dimensions with a larger number of items (e.g., Sincerity). Finally, as with the Big Five, the BP dimensions show differential effects on performance measures (as assessed by brand attitude) and thus support the predictive power of the single dimensions. The findings provide insights into the dimensional structure of BP and its stability, and support the transferability of the Big Five personality factors to nonhuman domains. Importantly, the article outlines relevant avenues for future research on BP measurement.  相似文献

The paper addresses the topic of e-procurement of logistics services and examines how the system that companies adopt to support this task affects the process performance. The system is evaluated in terms of substantive outcomes (e.g., logistics providers’ profits) and other performances related to perceptions and behavioral issues. Specifically, the considered system is characterized by the exchange mechanism that rules the transaction (multi-attribute auction vs. negotiation) and the level of problem complexity. The analysis, conducted via a laboratory experiment, shows that both the exchange mechanism and the problem complexity affect performance. Practical implications, which could help companies design effective e-procurement systems, are discussed.  相似文献

Academic literature addressing the topic of business ethics has paid little attention to cross-cultural studies of business ethics. Uncertainty exists concerning the effect of culture on ethical beliefs. The purpose of this research is to compare the ethical beliefs of managers operating in South Africa and Australia. Responses of 52 managers to a series of ethical scenarios were sought. Results indicate that despite differences in socio-cultural and political factors there are no statistically significant differences between the two groups regarding their own ethical beliefs. Results thus support the view that culture has little or no impact on ethical beliefs.Russell Abratt (DBA Pretoria) is Professor of Marketing at the University of Witwatersrand, Johannesburg, South Africa.

This paper investigates the regulation of ethical behavior of professionals. Ethical perceptions of South African professionals operating in the business community (specifically accountants, lawyers and engineers) concerning their need for and awareness of professional codes, and the frequency and acceptability of peer contravention of such codes were sought. The existence of conflict between corporate codes and professional codes was also investigated. Results, based on 217 replies, indicated that the professionals believe that codes are necessary and are relatively aware of the contents of such codes. Despite these ethical tendencies, respondents (particularly lawyers) believe that their peers contravene their professional codes relatively often. No significant differences in ethical tendencies between professionals consulting to and those working in business were found. Many respondents were regulated by more than one code of ethics, but few experienced conflict between such codes. In the events of conflict occurring professionals chose to adhere to their professional code above others.  相似文献

This paper assesses the stochastic convergence of relative \(\hbox {CO}_{2}\) emissions within 28 OECD countries over the period 1950–2013. Using the local Whittle estimator and some of its variants we assess whether relative per capita \(\hbox {CO}_{2}\) emissions are long memory processes which, although highly persistent, may revert to their mean/trend in the long run thereby indicating evidence of stochastic convergence. Furthermore, we test whether (possibly) slow convergence or the complete lack of it may be the result of structural changes to the deterministics of each of the relative per-capita emissions series by means of the tests of Berkes et al. (Ann Stat 1140–1165, 2006) and Mayoral (Oxford Bull Econ Stat 74(2):278–305, 2012). Our results show relatively weak support for stochastic convergence of \(\hbox {CO}_2\) emissions, indicating that only between 30 and 40% of the countries converge to the OECD average in a stochastic sense. This weak evidence disappears if we enlarge the sample to include 4 out of the 5 BRICS, indicating that our results are not robust to the inclusion of countries which are experiencing rates of growth which are far larger than those of the OECD members. Our results also decisively indicate that a slow or lack of convergence is not the results of a structural break in the relative \(\hbox {CO}_{2}\) emissions series.  相似文献

One of the key features of our economies consists of the coexistence of different technologies supplying similar products and services. We often observe that an old technology is improved when a new one appears; behind this process of improvement often lies an intentional research activity. There thus begins a competition between the two technologies whose performances are improved via R&D. We focus our attention on this competition process and supply a formal model, based on the optimization of R&D expenditure of both technologies, which can describe the dynamics of the delayed overtaking of the new technology over the old one.  相似文献

There is a growing interest in understanding consumer ethical actions in relation to their dealings with firms. This paper examines whether there are differences between Northern and Southern European Union (EU) consumers' perceptions of ethical consumer behaviour using Muncy and Vitell's (1992) Consumer Ethics Scale (CES). The study samples 962 university students across four Northern EU countries (Germany, Denmark, Scotland, The Netherlands) and four Southern EU countries (Portugal, Spain, Italy, Greece). Some differences are identified between the two samples, which might question the ability of organisations to consider the EU as one homogeneous market.  相似文献
