ABSTRACTIn this article we study the influences of esthetic, functional, and symbolic dimensions of design on attitude toward fjord cruise boats and intention to recommend using the product. Also, we argue for the importance of a product to blend in with the surroundings in which it is used – contextually congruent design. In two studies we find that aesthetic, functional and contextually congruent design has positive influences on attitude toward fjord cruise boats. Designers of fjord cruise boats should develop boats with designs that are congruent with the surroundings in which they will be used. 相似文献

The use of digital methods offers a chance to connect communication science with economics. In recent years, a growing body of research in economics has turned its attention to media content, assuming that journalistic coverage contains hitherto neglected information relevant for business cycles or financial market movements. Interestingly, these approaches largely ignore communication science’s established theories and empirical findings. This paper aims at building a bridge between the two disciplines. Its contribution is threefold: a) it provides an overview of the most important approaches in economics that incorporate media content; b) it operationalizes the concept of the “narrative”, as it is used in economics, and distinguishes it from the concept of the “frame”, essential in communication science; c) exemplifying our approach, we present a new Uncertainty Perception Indicator (UPI) based on the topic modeling method Latent Dirichlet Allocation (LDA), that enables us to isolate different factors of economic policy uncertainty contained in media coverage.Economic studies treat journalistic media content as a proxy for sentiment prevalent in society. Typically, they rely on frequency analyses of certain keywords, like “recession” or “inflation”. Even more sophisticated approaches, such as Shiller (2017), who calls for establishing a new branch of “narrative economics”, or Baker et al. (2016), who construct a comprehensive set of media-based indicators, make no or little reference to communication science. This neglect could be discounted as pure ignorance, but this misses the point. Being a predominantly empirical discipline today, economics relies on long time-series of data, that have not been available for media content, a gap rendering the two disciplines largely incompatible.The gap is also reflected in terminology. “Frame” is a major analytical concept in communication science, while the term “narrative” has become in vogue in economics. Although both concepts are closely connected, they are rarely properly distinguished from each other. “Frame” can be considered as a rather static concept that applies during a limited period of time. “Narrative”, in contrast, implies dynamic properties, i.?e., the sorting of events, causes and effects over time, that explain how the current state of the world has come about, as stressed by Tenenboim-Weinblatt et al. (2016).In this paper, we propose a synergetic concept. Following Entman (1993), a media frame contains four elements: a) a problem definition, b) a problem diagnosis, c) a moral judgement, and d) possible remedies. We augment this approach by adding two more elements. According to our definition, a media narrative comprises a frame, or several ones, plus e) one or several protagonists—persons, institutions, or social groupings (nations, classes, etc.)—, whose relationships are (often) antagonistic and may change over time; and f) events, that are chronologically integrated and that are (often) assumed to constitute causal relationships. To put it metaphorically: a frame is to a narrative what a still photo is to a movie. Both are valuable concepts; the still photo shows more details, while the movie provides a contextualization over time.Topic models like LDA are valuable tools for the measurement of media narratives. The probabilistic approach enables researchers to conduct what may be called “macro-content analyses”, an exercise that focuses on average reporting patterns in large text corpora and can be translated into numerical time-series, thereby facilitating compatibility with empirical economics. Based on a topic’s frequency analysis, its top words and top articles, “mean media narratives” can be formulated, that integrate certain events, protagonists and frames.In our case study, we exemplify this concept by applying it to an indicator that is currently popular in economics, the Economic Policy Uncertainty Index (Baker et al. 2016). The EPU aims at capturing political developments that are exogenous to economic models and therefore unpredictable. Essentially, the indicator is based on the counts of articles containing a set of search words, such as “uncertain”, “economic” as well as institutions like the European Central Bank. Using identical search words as the EPU for Germany, we construct a similar corpus for the years 1994 to 2017. By conducting an LDA-based analysis, we are able to extract additional relevant information from the data. In particular, the evolution of different uncertainty factors and their development over time can be detected.Our Uncertainty Perception Indicator (UPI) contains six relevant news topics that are highly relevant for market developments: central banks, the national government, international politics, the business cycle, companies, and society. While the EPU merely shows how often uncertainty concerning economic policy is mentioned in the media, the UPI also indicates the origins of uncertainty. By grouping the six topics into three analytical categories—governments, markets, and society—we find a distinct break in the time-series. Before the financial crisis of 2008, the perception of uncertainty was rather balanced between the three factors. Since then, however, economic uncertainty has mainly been driven by political actors, most prominently by central banks. The corresponding narratives are a two-chapter story: in the first part, up to 2008, stable financial markets and smoothed business cycles prevailed, making central banking a rather straight-forward task. The second part is characterized by multiple crises, leaving central banks as dominant actors, that intervened with unconventional measures. Thereby, they became stabilizing forces, but at the same time sources of uncertainty with respect to the timing and the impact of these measures. 相似文献

A pressure group model where environmental and industry lobby groups offer political support in return for favorable pollution tax policies is used to explain and predict the equilibrium pollution tax in sectors protected by tariffs. The political economy effects of trade liberalization are investigated. The pollution tax is shown to decrease if the lobbying effort by the environmental lobby decreases more rapidly than by the industry lobby ceteris paribus. The level of political conflict falls with trade liberalization. Pollution may increase because of a reduction of the pollution tax, and tax revenues may fall simultaneously as pollution increases. 相似文献

In this article, I argue that organizations' historical narrativesare a basic and important component of their culture and identity,and that these narratives can be resources as well as constraints.I combine a narrative approach with Joanne Martin's three perspectivetheory of organizational culture, and using the transformationof Danish savings banks as a case, I demonstrate how a narrativeapproach can provide a new and better understanding of organizationalbehaviour and change than mainstream economics and the abundantfunctionalist organizational culture literature. I demonstratehow, when change was called for by external pressures, the savingsbanks choice set was constrained by a shared narrative abouttheir historical origins. This narrative, in turn, constitutedthe identity, image and organizational culture of savings banksand to a high degree restrained learning capabilities, createdorganizational inertia and delayed the adoption of a new strategy. 相似文献

This paper explores the role of self‐identity expressiveness and social identity expressiveness in the context of Multimedia Messaging (MMS) adoption. An extended version of the Theory of Planned Behavior (TPB) including a wider array of identity and social influences is developed and tested. As hypothesized, self‐identity expressiveness and social identity expressiveness prove to be significant determinants of intentions to use. Moreover, the extended TPB model explains 62% of the variance in usage intentions. The paper also investigates the relationship between self identity expressiveness and attitude and between social identity expressiveness and subjective norm. The study results indicate that the concept of subjective norm alone is insufficient to capture the rich universe of identity and social influences driving behavioral intentions. Implications for marketing managers and scholars are discussed. © 2007 Wiley Periodicals, Inc. 相似文献

Newly launched products in the consumer goods and services markets show high failure rates. To reduce the failure rates, companies can integrate innovative and knowledgeable customers, the so‐called lead users, into the new product development process. However, the detection of such lead users is difficult, especially in consumer product markets with very large customer bases. A new and potentially valuable approach toward the identification of lead users involves the use of virtual stock markets, which have been proposed and applied for political and business forecasting but not for the identification of experts such as lead users. The basic concept of virtual stock markets is bringing a group of participants together via the Internet and allowing them to trade shares of virtual stocks. These stocks represent a bet on the outcome of future market situations, and their value depends on the realization of these market situations. In this process, a virtual stock market elicits and aggregates the assessments of its participants concerning future market developments. Virtual stock markets might also serve as a feasible instrument to filter out lead users, primarily for the following two reasons. First, a self‐selection effect might occur because sophisticated consumers with a higher involvement in the product of interest decide to participate in virtual stock markets. Second, a performance effect is likely to arise because well‐performing participants in virtual stock markets show a better understanding of the market than their (already self‐selected) fellow participants. So far, only limited information exists about these two effects and their relation to lead user characteristics. The goal of this paper is to analyze the feasibility of virtual stock markets for the identification of lead users. The results of this empirical study show that virtual stock markets can be an effective instrument to identify lead users in consumer products markets. Furthermore, the results show that not all lead users perform well in virtual stock markets. Hence, virtual stock markets allow identifying lead users with superior abilities to forecast market success. 相似文献

This paper considers the implications of international policy coordination when both monetary and fiscal policy choices are endogenous. We show that a movement from insular monetary commitment to international monetary policy coordination will, if fiscal policies are not coordinated, produce higher output and public expenditure levels at the expense of higher inflation rates. We also show that the concurrent coordination of monetary and fiscal policies raises output and inflation while lowering public expenditure relative to a regime of monetary coordination alone. We conclude that the arguments for concurrent monetary and fiscal policy coordination fail to have a clear-cut theoretical basis. 相似文献

This paper applies a statistical approach used by Andersen & Hylleberg (1993) in their study of insider-outsider effects in wage-employment determination in the Danish manufacturing sector, to analyse insider-outsider effects in the Swedish private sector. Focusing on the univariate and multivariate trend properties of the data, a bivariate wage-employment error correction model is used as an explicit test-bed for the theoretical predictions of adjustments to anticipated and unanticipated shocks. According to the Blanchard & Summers (1986) insider-outsider model, the former changes are absorbed entirely by wages while the latter changes are reflected fully in employment. As in the case of analysis on Danish manufacturing data, it is found that the evidence based on data related to the Swedish private sector also fails to accept the Blanchard & Summers insider-outsider model in its unqualified version. Nonetheless several important traits of insider-outsider mechanisms seem to be in accordance with the observed evolution of the data. 相似文献

Policy related transaction costs (TCs) is an important issue when evaluating different policy options. However, TCs are often not taken into account in policy evaluations, but may be as important for efficiency as the direct production costs. Different policies may result in different TCs, and the main aim of this article is to explore possible reasons for these differences. We compare the level of TCs for 12 different agricultural policy measures in Norway, and we analyze the causes of the differences along three different dimensions: asset specificity, frequency, and point of policy application. At the national level we find that all three dimensions are of importance when explaining the differences, while variation in TCs incurred by farmers are mainly due to differences in point of policy application and asset specificity. Data show that direct price support has the lowest TCs, while more direct payments for environmental amenities has the highest. 相似文献

A note on Wick products and the fractional Black-Scholes model 总被引:1,自引:0,他引:1
In some recent papers (Elliott and van der Hoek 2003; Hu and Øksendal 2003) a fractional Black-Scholes model has been proposed as an improvement of the classical Black-Scholes model (see also Benth 2003; Biagini et al. 2002; Biagini and Øksendal 2004). Common to these fractional Black-Scholes models is that the driving Brownian motion is replaced by a fractional Brownian motion and that the Itô integral is replaced by the Wick integral, and proofs have been presented that these fractional Black-Scholes models are free of arbitrage. These results on absence of arbitrage complelety contradict a number of earlier results in the literature which prove that the fractional Black-Scholes model (and related models) will in fact admit arbitrage. The objective of the present paper is to resolve this contradiction by pointing out that the definition of the self-financing trading strategies and/or the definition of the value of a portfolio used in the above papers does not have a reasonable economic interpretation, and thus that the results in these papers are not economically meaningful. In particular we show that in the framework of Elliott and van der Hoek 2003, a naive buy-and-hold strategy does not in general qualify as self-financing. We also show that in Hu and Øksendal 2003, a portfolio consisting of a positive number of shares of a stock with a positive price may, with positive probability, have a negative value.Received: August 2004, Mathematics Subject Classification (2000):
