COMPARING LOCAL RISKS BY ACCEPTANCE AND REJECTION

It is said that risky asset h acceptance dominates risky asset k if any decision maker who rejects the investment in h also rejects the investment in k. While in general acceptance dominance is a partial order, we show that it becomes a complete order if only infinitely short investment time horizons are considered. Two indices that induce different variants of this order are proposed, absolute acceptance dominance and relative acceptance dominance, and their properties are studied. We then show that many indices of riskiness that are compatible with the acceptance dominance order coincide with our indices in the continuous‐time setup.     

Identifying an Advertisement Presenter's Tribe

ABSTRACT

In African countries it is generally important to identify another person's tribe when meeting that person for the first time. A similar process of identification also seems to take place when a consumer sees a presenter in an advertisement. This paper identifies the cues that are used in tribal identification, demonstrates that multiple cues are employed, and shows that nonvisual cues are generally more important than visual ones. It also finds that audience members notice a presenter's tribe more frequently in advertisements appearing on television than in those appearing in print or outdoor media. The managerial implications of these findings are discussed.     

Lending to small businesses: the role of loan maturity in addressing information problems

We investigate what determines the maturity of lines of credit to small businesses. Our results provide strong support for the hypothesis that shorter loan maturities serve to mitigate the problems associated with borrower risk and asymmetric information that are typical of small business lending. We find that maturity is shorter for firm owners that have poor credit histories, are older, and less experienced, and for firms that are more informationally opaque. Supporting the notion that collateral and maturity are substitute mechanisms in mitigating agency problems, we also find strong evidence that maturity increases with collateral pledges, that personal collateral is associated with longer maturities than business collateral, and that collateral types that better mitigate agency problems reduce the sensitivity of loan maturity to informational asymmetries and risk. Finally, while it is argued that relationship lending may mitigate information asymmetry, we find no relation between loan maturity and stronger firm-creditor ties.

But you promised! Managing consumers’ psychological contracts

In management literature, a psychological contract generally refers to an employee's beliefs about the reciprocal obligations that exist between him or her and an organization. Legal contracts, on the other hand, are agreements that create obligations between the parties that are enforceable by law. Psychological contracts are different from legal contracts in that they are characterized by the belief that both parties have entered into a set of mutual obligations. While marketing scholars and practitioners have largely overlooked the notion of psychological contracts, this article argues that a firm's customers might view the promises they believe a firm has made to them as psychological contracts. Psychological contracts are as relevant to marketing as they are to management. This article expands the notion of psychological contracts to marketing relationships and outlines internal and external strategies firms can employ to manage psychological contracts more effectively.     

Cooperative and non-cooperative R&D and trade costs

We examine the effect of trade liberalization on the level and mode of R&D in an international duopoly setting. Firms have the choice to invest in R&D either independently or cooperatively. A reduction in trade cost increases R&D irrespective of the mode of R&D. However, an increase in spillovers has ambiguous effects on R&D. More precisely, we find that an increase in spillover leads to higher R&D activity under cooperation but lower R&D activity under non-cooperation. Concerning cooperation versus non-cooperation, we find that firms prefer cooperation only if trade costs are low. Consumers are better off under cooperation if spillovers are high. We find that there can be a mismatch between private and social incentives. If spillovers are low and trade costs are low then cooperation might be privately profitable but socially undesirable. On the other hand, if there are large spillovers and high trade costs then cooperation may be socially desirable but not privately profitable.     

A Wolf in Sheep’s Clothing: The Use of Ethics-Related Terms in 10-K Reports

We examine the occurrence of ethics- related terms in 10-K annual reports over 1994–2006 and offer empirical observations on the conceptual framework of Erhard et al. (Integrity: A Positive Model that Incorporates the Normative Phenomena of Morality, Ethics, and Legality (Harvard Business School, Harvard) 2007). We use a pre-Sarbanes-Oxley sample subset to compare the occurrence of ethics-related terms in our 10-K data with samples from other studies that consider virtue-related phenomena. We find that firms using ethics-related terms are more likely to be “sin” stocks, are more likely to be the object of class action lawsuits, and are more likely to score poorly on measures of corporate governance. The consistency of our results across these alternative measures of ethical behavior suggests that managers who portray their firm as “ethical” in 10-K reports are more likely to be systematically misleading the public. These results are consistent with the integrity-performance paradox.     

Do Equally Owned Small Businesses Have Equal Access to Credit?

Previous research in small-business financing has generally ignored those businesses owned equally by males and females. The rationale has been that such businesses share the characteristics of both types of owners and would confound any gender-based differences. This paper presents an empirical study in which the credit access experiences of equally owned small businesses are compared to those of their female- and male-owned entrepreneurial counterparts. Various measures of credit constraints are introduced that suggest that equally owned businesses often do experience larger constraints than male-owned businesses and smaller constraints than female-owned businesses, when all credit applicants are considered. However, the results are more mixed in comparisons of successful applicants’ constraints. A different approach from that of existing research is then used to study exactly how equally owned small businesses’ experiences are unique, rather than merely whether they differ from those of their counterparts. The evidence indicates that different factors are determining the credit application outcomes of all three ownership groups. Where similar determinants are found, equally owned businesses are influenced in a manner more similar to male-owned small businesses. The results show that equally owned small businesses’ credit access experience is not equally balanced between those of their counterparts.      

Online entrepreneurial communication: Mitigating uncertainty and increasing differentiation via Twitter

Research shows that some narratives and symbolic actions produced by entrepreneurial firms can help to reduce audience uncertainty about their quality and differentiate them from rivals. But can communications via online social media channels – which we characterize as “communicative streams” – be used to reduce uncertainty and enhance differentiation? This seems debatable, given that such streams comprise multiple, brief messages (a) that encode signals lacking narrative cohesion; (b) are only fleetingly accessible; and (c) are minimally customized. We address this puzzle using qualitative methods to compare the communications enacted by eight firms that are using Twitter in order to pursue growth. Our theoretical contribution rests in positing links between specific types of communicative streams and audience responses that reflect reduced uncertainty or enhanced differentiation. Our analysis suggests that firms enacting a “Multi-dimensional” communicative stream (which entails a high volume of posts, a high proportion of which signal quality, relational orientation, distinctiveness, and positive affect) are most likely to elicit audience affirmation of firms' quality and/or distinctiveness. Implications for theory, research methods and practice are discussed.     

Small firms,business dynamics and differential development of economic well-being

In recent years a growing stream of research has examined the relationships between structural characteristics of regions and their levels of new firm formation. This empirical study aims at supplementing such findings with analyses that include other forms of business dynamics, and also the possible well-being effects of such dynamics. From a unique and comprehensive data set that tracks all births, deaths, expansions, and contractions of commercial business establishments in Sweden 1985–89, six groups of regions with different patterns of dynamics are extracted by means of cluster analysis. The clusters' structural characteristics and their development of economic well-being are also compared. The results suggesta) that the patterns of business dynamics are contingent on the structural characteristics of regions,b) that high formation and turnover of establishments are associated with a relative increase in economic well-being, andc) that small, autonomous firms have a vital role in this process.     

The Business of Business is the Human Person: Lessons from the Catholic Social Tradition

I describe an ethic for business administration based on the social tradition of the Catholic Church. I find that much current thinking about business falters for its conceit of truth. Abstractions such as the shareholder-value model contain truth – namely, that business is an economic enterprise to manage for the wealth of its owners. But, as in all abstractions, this truth comes at the expense of falsehood – namely, that persons are assets to deploy on behalf of owners. This last is “wrong” in both senses of the word – it is factually wrong in that persons are far more than business assets, they are supernatural beings, children of God; and it is morally wrong in that it is an injustice to treat them as the former when they are the latter. I draw upon the social tradition of the Catholic Church to recognize that the business of business is not business, but is instead the human person. Following Church teachings, I describe a person-centered ethic of business based upon eight social principles that both correct and enlarge the shareholder-centered ethic of much current business thinking. I discuss implications of this person-centered ethic for business administration.     

Does food advertising influence children’s food choices? A critical review of some of the recent literature

Food advertising to children is an issue that is at the centre of debate and the purpose of this paper is to critically examine the claims and the evidence. Several issues are examined: the child’s understanding of advertising, the content of advertising to children; food choices in families, children’s food choice and behaviour, and the effect of advertising on food choice. Major conclusions are the following: that children understand the function of advertising from the age of 8–9 years, although there are limitations on how effectively they apply this knowledge; that the content of advertising to children has remained relatively unchanged for 25 years; that children play an active role in food choice in families; that children’s dietary preferences and habits are well-established before advertising is understood; and that advertising’s role in children’s food choices and preferences is multi-factorial and complex.     

Managerial ethics and microeconomic theory

There is a very apparent conflict between economists and ethicists over the moral standards that should be applied to the managers of business firms. The view of most economists is that moral standards in business are not relevant, beyond the normal personal obligations to speak the truth and observe the law, because profit maximizing behaviour, under market and resource constraints, leads inexorably to social welfare optimization. The opposing view of most humanists is that modern markets are not competitive enough to be constraining, that profit maximization often leads to social harm, and that welfare benefits are unjustly distributed. The article examines the moral constructs in microeconomic theory and the ethical objections to that theory at both the pragmatic and theoretic levels, and concludes that inappropriate assumptions about the nature and worth of human beings in the economic paradigm require the use of moral standards for business decisions and actions.

The market microstructure of central bank intervention

How quickly do central bank intervention operations impact the foreign exchange market? And, do intra-daily market conditions influence the effectiveness of central bank interventions? This paper uses high-frequency intra-daily data to examine the relationship between the efficacy of intervention operations and the “state of the market” at the moment that the operation is made public. The results indicate that some traders typically know that the Fed is intervening at least 1 h prior to the public release of the information in newswire reports. Also, the evidence suggests that the timing of intervention operations matters—interventions that occur during heavy trading volume, that are closely timed to scheduled macro announcements, and that are coordinated with another central bank are the most likely to have large effects.     

Designing the content of advertising in a differentiated market

In many markets, consumers use attribute information to assess the value they expect from purchasing a product or service. This includes many low involvement experience goods including take-out food, many packaged good categories and restaurants. In these markets, quality differences exist but many differences are horizontal in nature: the consumer is interested in finding a product that meets her unique tastes. Beyond ensuring that consumers know the brand, the category and the price; it seems advertising should provide consumers with attribute information. However, a significant proportion of advertising does not provide it. In fact, within the same category, competitors respond to messages that emphasize detailed attribute information with messages that are devoid of attribute information. These messages are uninformative about product attributes. We explore how competition in a differentiated market is affected by the ability of a firm has to choose uninformative messages. We construct a model to investigate the factors that affect a firm’s decision to use advertising with detailed attribute information or advertising that does not provide it. The model demonstrates that content decisions about advertising are affected by the differences between products, the range of heterogeneity in consumer tastes and the degree to which costs increase as a function of the quantity of information in advertising. Surprisingly, even when the cost to increase the quantity of information in advertising is low, uninformative campaigns can be more profitable than campaigns with attribute information. The analysis also demonstrates that firms can be more likely to provide attribute information when there are less consumers that are attribute-sensitive. Finally, the model shows that uninformative messages can create “artificial differentiation” in some situations.     

Cross-Cultural Retailing Research

Abstract

Relatively little is known about consumer perceptions of retailers in Central and Eastern Europe. What store attributes do consumers in these markets emphasize? Do these attributes reflect the culture of the region? These questions are addressed in the case of Estonia. However our main objective is to contrast the Estonian situation with that of a typical Western country, Canada. Two key shopping experience constructs are selected, namely merchandise selection and the interactivity between the store and the consumer. To make the comparison meaningful we have chosen a single retail category, namely discount or low-price department stores. In both countries there were two stores that dominated their respective market, so this facilitates the collection of consumer perceptions. Structural equation modeling using AMOS software has been used to test the equivalence of the constructs across cultures. Our main findings are that (1) both merchandise selection and store-customer interaction are valid constructs across both countries, (2) that the factor patterns have configural invariance or equivalence for each construct across the two cultures and (3) that the factor patterns do not have weak factor invariance across the cultures. In short, we conclude that there are major differences in consumer's discount store shopping experiences across the two cultures.     

A Word to the Wise: How Managers and Policy-Makers can Encourage Employees to Report Wrongdoing

When successful and ethical managers are alerted to possible organizational wrongdoing, they take corrective action before the problems become crises. However, recent research [e.g., Rynes et al. (2007, Academy of Management Journal 50(5), 987–1008)] indicates that many organizations fail to implement evidence-based practices (i.e., practices that are consistent with research findings), in many aspects of human resource management. In this paper, we draw from years of research on whistle-blowing by social scientists and legal scholars and offer concrete suggestions to managers who are interested in encouraging internal reporting of problems requiring attention, and to observers of questionable activity who are considering reporting it. We also identify ways that research suggests policy-makers can have a more positive influence. We hope that these suggestions will help foster evidence-based practice regarding whistle-blowing.     

The Benefits of IT-Based Supply Chains-Strategic or Operational?

ABSTRACT

Business relationships are being revolutionized by the use of inter-organizational information systems (IOSs) that connect together separate companies' business processes through the application of Information Technology (IT). The physical value chain is now paralleled by the virtual information chain. Detailed case studies from earlier research suggest that there are huge benefits to be gained from concepts such as Electronic Data Interchange (EDI), shared product design databases and shared production scheduling systems. However, there is little empirical evidence of the overall usage and outcomes of IOS implementation. In this survey, IOS benefits are evaluated using marketing derived frameworks. Evidence from 89 United Kingdom (UK)-based organizations, a large proportion of which are trading internationally, suggests that IOSs are becoming pervasive across different business processes and across different types of industry. The analysis reveals that marketing activities are now dominated by the management of the information along the supply chain and that significant benefits can be realized. However, the time-scale for implementing such systems is of the order of 5 to 10 years and there are significant barriers to successful implementation.     

So,you want to be an entrepreneur? Lessons from the Entrepreneurship Bootcamp for Veterans with Disabilities

Based on helping dozens of military veterans refine their ideas for starting a business, we identify and discuss a series of potential pitfalls that aspiring entrepreneurs—veterans and civilians alike—must avoid in order to be successful. Potential entrepreneurs must not confuse the pursuit of hobbies and self-employment with the act of creating a business. People who wish to build a business around public speaking or consulting need to firmly establish why customers should be willing to pay for their advice. Individuals that seek to develop a new non-profit organization must have a viable value proposition even though they are not pursing a profit motive. Overall, the entrepreneurial ventures that are most likely to succeed are those that (1) are based on a sustainable business model, (2) leverage the entrepreneur's unique experiences and attributes, and (3) are built around a process or system that enables the venture to prosper even if the entrepreneur leaves the venture.     

Managers' mobility,trade performance,and wages

Knowledge is key to the competitiveness and success of an organization and in particular of a firm. Firms and their managers acquire knowledge via a variety of different channels which are often difficult to track down and quantify. By matching employer–employee data with trade data at the firm level we show that the export experience acquired by managers in previous firms leads their current firm toward higher export performance, and commands a sizeable wage premium for the manager. Moreover, export knowledge is decisive when it is market-specific: managers with experience related to markets served by their current firm receive an even higher wage premium; firms are more likely to enter markets where their managers have experience; exporters are more likely to stay in those markets, and their sales are on average higher. Our findings are robust to controlling for unobserved heterogeneity and, more broadly, endogeneity and indicate that managers' export experience is a first-order feature in the data with an impact on a firm's export performance that is, for example, at least as strong as that of firm productivity.     

Globalization and Poverty: Oxymoron or New Possibilities?
