A reealuation of the attentional inertia concept

Anderson's theory about children's attention behavior during television viewing hypothesizes that attention behavior is affected by (a) positive feedback (the inertia hypothesis), and (b) the degree to which a child understands the television program. During an experiment neither component of Anderson's theory was upheld. It was found that children's attention behavior is patterned and stable over time; children either have short or long attention spans. The implications for advertisers are examined.     

Plugs versus placements: A comparison of alternatives for within‐program brand exposure

A study is presented that compares two forms of within‐program brand appearances: product placements and celebrity plugs. Evidence suggests that plugs may often have a retention advantage over placements. This advantage is hypothesized to arise from differences in the way plugs and placements are often presented. Specifically, differences in presentation contexts may create differences in how memory for plugs and placements is organized. This, in turn, may allow plugs to receive more frequent rehearsal during subsequent viewing of a show in which a brand has appeared. © 2004 Wiley Periodicals, Inc.     

Survival of commodity trading advisors: 1990–2003

This article investigates the mortality of Commodity Trading Advisors (CTAs) over the 1990–2003 period, a longer horizon than any encompassed in the literature. A detailed survival analysis over the full range of CTA classifications is provided, and it is found that the median lifetime of CTAs in this sample is different than previously documented. Through the implementation of nonparametric, parametric, and semiparametric statistical techniques, it is emphasized that CTA survivorship is heavily contingent on the strategy followed by the fund. Furthermore, a significant positive size effect on survival is shown, whereas poor returns, and to a lesser extent, high‐risk exposure, appear to hasten mortality. © 2005 Wiley Periodicals, Inc.

Information content of cross‐sectional option prices: A comparison of alternative currency option pricing models on the Japanese yen

This article implements a currency option pricing model for the general case of stochastic volatility, stochastic interest rates, and jumps in an attempt to reconcile levels of risk‐neutral skewness and kurtosis with observed option prices on the Japanese yen and to analyze the information content of the cross section of option prices by investigating the hedging and pricing performance of various currency option pricing models. The study makes use of both a method of moments and a more traditional generalized‐least‐squares (GLS) estimation technique, taking advantage of the fact that methods of moments do not specifically require the use of cross‐sectional option prices, whereas GLS does. Results centered around the Asia economic crisis of 1997 and 1998 indicate that the cross section of option prices surprisingly does not appear to contain superior information as the two estimation techniques yield relatively similar results once idiosyncratic differences between them are acknowledged. Extensions of the G. Bakshi, C. Cao, and Z. Chen (1997) results to currencies are also provided. © 2006Wiley Periodicals, Inc. Jrl Fut Mark 26:33–59, 2006     

The Effect of Stylistic Product Information on Consumers’ Aesthetic Responses

This paper investigates the effect of stylistic information about a product, defined as verbal product information aimed at helping consumers to interpret a product's visual design, on consumers’ aesthetic responses. The results of three experimental studies show that for consumers with higher centrality of visual product aesthetics (CVPA), stylistic information positively influences aesthetic responses through perceived meaningfulness of product design (i.e., the extent to which an individual is able to make sense of a product's visual appearance and understands what it represents). Further, these effects translate into consumers’ purchase intentions. For consumers with lower CVPA, stylistic information neither affects aesthetic responses nor perceived meaningfulness of product design. These findings contribute to existing research on consumers’ aesthetic processing by highlighting the importance for consumers to grasp a product's design meaning in order to maximally appreciate its visual appeal.     

Subnational managerial transformation and the post‐WTO‐accession business environment in China: Shanghai perspectives

The market‐oriented perspectives held by managers of China's municipal government agencies and urban enterprises constitute critical variables in the business environment encountered by foreign investors. A study of 426 predominantly subnational managers in Shanghai found most study participants generally positively inclined toward implementing accession‐related reforms and toward marketoriented developments. The study also revealed a surging interest in careers with foreign‐affiliated entities and widespread preference for incentives that give foreign‐invested firms a competitive hiring and retention advantage over domestic, especially state, establishments. The overall results suggest the transformation of subnational managerial orientations in a direction that is conducive for foreign participation in Shanghai's postaccession economy. © 2005 Wiley Periodicals, Inc.

Impact of host‐country corruption on U.S. and Chinese cross‐border acquisitions

Does corruption in a target country create a similar effect on cross‐border acquisitions (CBAs) by firms from a developed and a developing country? This article empirically examines the relationship between corruption and CBAs by firms from China and the United States. Based on a combined sample of 10,236 completed acquisitions over the period of 1990–2006, the authors find that both Chinese and U.S. firms make a significantly greater number of acquisitions in less corrupt countries. However, unlike the U.S. CBAs, we find a significantly positive relationship between the transaction value of Chinese CBAs and the level of perceived corruption in the target country. It is suggested that having been schooled in weaker institutions themselves, Chinese firms may find it easier to deal with corrupt conditions in target countries, giving them an advantage over firms from less corrupt countries. © 2010 Wiley Periodicals, Inc.     

Leveraging local knowledge or global advantage: Cross border bank mergers and acquisitions in Africa

This paper examines global financial markets perception of value creation for banks from across the world initiating or expanding their operations on the African continent through mergers and acquisitions (M&As) over the period 2000–2018. Especially before and during the financial crisis, we document a strong advantage of Pan-African Banks (PABs) over domestic and emerging market banks and a slight advantage over advanced market banks. These results are in line with the hypothesis that PABs benefitted from both a global expertise and local knowledge advantage in the market for corporate control. We also document how retrenchment of global banks during and in the aftermath of the global financial crisis have created opportunities for PABs.     

The Why's of Business Revisited

One can determine the nature of something by asking what it is for. For example one understands what a chair is when one understands it is for sitting on. This involves understanding its purpose. One type of corporation is the for-profit-corporation. This seems to indicate that this type of corporation, the business corporation, has as its purpose to make a profit. Is that as obvious as it first appears? The favorite way for philosophers to arrive at the "purpose" of anything is to ask the question "Why?" But there are at least two answers to the question "Why"? when addressed to a social practice such as business. One might be asking for a psychological account (explanation) of "Why" a person does business, and this is primarily answered by discovering the motives behind business activity; or one might be asking for a justificatory reason (justification) for the practice – what purpose legitimates business as a human activity. These two answers are often conflated and thus the purpose of business is often considered to be answered by giving the psychological account of the self-interested profit-making motive. This paper will attempt to highlight the importance of making the distinction between motive and purpose clearly, show what confusions arise when the distinction is ignored, and hint at some of the structural philosophical reasons why the distinction got blurred in the first place.     

The true meaning of David Ricardo’s four magic numbers

The four numbers in David Ricardo’s example of comparative advantage have been traditionally interpreted as unit labor coefficients in the production of wine and cloth in UK and Portugal. A recent interpretation suggests that they represent instead the labor needed to produce the amounts of wine and cloth actually traded. Ricardo’s four numbers are shown to yield each country’s gains from trade by simply subtracting two of the numbers from the other two. Since the numbers also indicate each country’s comparative advantage, Ricardo established a close connection between comparative advantage and the gains from trade.     

Monetary policy and risk management at a time of low inflation and low unemployment

I do not see it as likely that the Phillips curve is dead, or that it will soon exact revenge. It is more likely that many factors, including better conduct of monetary policy over the past few decades, have greatly reduced, but not eliminated, the effects that tight labor markets have on inflation. However, no one fully understands the nature of these changes or the role they play in the current context. Common sense suggests we should beware when forecasts predict events seldom before observed in the economy.     

Tariff wars in the Ricardian Model with a continuum of goods

This paper describes strategic tariff choices within the Ricardian framework of Dornbusch, Fischer, and Samuelson (1977) using CES preferences. The optimum tariff schedule is uniform across goods and inversely related to the import demand elasticity of the other country. In the Nash equilibrium of tariffs, larger economies apply higher tariff rates. Productivity adjusted relative size (≈ GDP ratio) is a sufficient statistic for absolute productivity advantage and the size of the labor force. Both countries apply higher tariff rates if specialization gains from comparative advantage are high and transportation cost is low. A sufficiently large economy prefers the inefficient Nash equilibrium in tariffs over free trade due to its quasi-monopolistic power on world markets. The required threshold size is increasing in comparative advantage and decreasing in transportation cost. I discuss the implications of the static Nash-equilibrium analysis for the sustainability and structure of trade agreements.

Competitive advantage: A longitudinal analysis of the roles of data-driven innovation capabilities,marketing agility,and market turbulence

While data-driven innovation capabilities have received considerable attention from academics and practitioners, there is insufficient longitudinal evidence on how they might contribute to improved marketing agility and competitive advantage. In this study, we make a preliminary effort to address this gap by developing a model based on the dynamic capabilities view. We also explore the moderating effects of market turbulence on the link among marketing agility and competitive advantage. We used two-waves data (T = 677 and T+1 = 569) and the cross-lagged panel approach was utilised to analyse the longitudinal data. Our findings provide robust empirical evidence on the causal and predictive temporal impact of data driven innovation capabilities on marketing agility and competitive advantage. It also indicated that marketing agility mediates this relationship over time. Moreover, the analysis suggested that market turbulence reinforce the influence of marketing agility on competitive advantage. We provided significant implications for theory and practice.     

The skill premium and economic growth with costly investment,complementarities and international technological-knowledge diffusion

We analyse the skill premium and the growth rate in an innovator-imitator general equilibrium growth model assuming (i) internal costly investment in both physical capital and R&D, (ii) complementarities between intermediate goods in production and (iii) technological-knowledge diffusion. We find that in the imitator country these three elements influence the economic growth rate and the skill premium. In the innovator country, while the growth rate is affected by costly investment and complementarities, the skill premium is not affected by any of our assumptions. It depends solely on the productive advantage of high-skilled over low-skilled labour, which suggests that the sustained increase in the skill premium observed in several developed countries over the last three decades may have been due to increases in such productive advantage.     

Evaluating sponsorship through the lens of the resource-based view: The potential for sustained competitive advantage

The resource-based view (RBV) of the firm has become a prominent management theory that firms can use to analyze resources as potential sources of competitive advantage. Theorists have suggested sponsorship of sport properties as one such resource, yet specific cases of sponsorship's role in a firm's achievement of a sustained advantage over competitors have yet to be explored. This article illuminates the case of Visa's longstanding global sponsorship of the Olympic Games, which was initiated and leveraged to counteract competitor American Express’ advantage with global business travelers. Evidence is presented that supports Visa's achievement of a competitive advantage during the term of the sponsorship. The case is then used to develop a conceptual model based on the RBV to identify the key characteristics of sponsored properties capable of assisting the sponsoring firm in achieving a sustained competitive advantage. From a managerial perspective, the model is designed to assist marketing managers tasked with the identification and evaluation of potential sponsorship properties.     

Perceived quality and image: When all is not “rosy”

The “meaning” of a brand resides in the minds of consumers, based on what they have learned, felt, seen, and heard over time. This study explores the relationship between quality and image with special attention on brands plagued with negative impressions, including instances where consumers' perceptions of a product's quality conflict with its perceived “image”. Data confirm that quality and image impact attitudes in a distinct manner, and overall, low brand image is more damaging than low quality. In addition, findings show that (1) hedonic attitudes towards brands are most driven by image, whereas utilitarian attitude formation/change processes are dominated by quality, (2) non-attribute brand beliefs are a stronger predictor of hedonic attitudes when quality or image is low versus high, while (3) attribute-based beliefs are strong predictors of utilitarian attitudes across image and quality levels.
