Endogenous Mergers of Complements with Mixed Bundling

This paper studies endogenous mergers of complements with mixed bundling, by allowing both for joint and separate consumption. After merger, partner firms decrease the price of the bundled system. In addition, when markets for individual components are sufficiently important, partner firms find it strategically advantageous to raise the prices of stand-alone products, thus making substitute ‘mix-and-match’ composite products less attractive to consumers. Even though these effects favor the profitability of mergers, merging is not always an equilibrium outcome. The reason is that outsiders respond by cutting their prices to retain their market share, and mergers can be unprofitable when competition is intense. From a welfare analysis, we observe that the number of mergers that are observed in equilibrium may be either excessive (when markets for individual components are important) or suboptimal (when markets for individual components are less important).     

Health-related attitudes as a basis for segmenting European fish consumers

This paper identifies and profiles consumer segments based on health-related attitudes. Cross-sectional data were collected in 2008 through a pan-European consumer survey (n = 2400) with samples representative for age and region in France, Poland and Spain. Four distinct consumer segments based on health-related attitudes are identified: low interest in healthy eating consumers (29.4%), positive health enthusiasts (28.2%), health strivers (35.0%) and health uninvolved (7.4%). The segments differ significantly with respect to fish consumption, attitudes and knowledge about the health benefits of fish, interest in potential informational cues when purchasing fish, and individual socio-demographic characteristics. The segment low interest in healthy eating is characterised by younger age, more males, higher BMI, low fish consumption and low interest in information, and herewith emerges as a relevant though difficult to reach segment from a food and health policy perspective. Positive health enthusiasts and health strivers have a strong involvement with food, and a strong interest in healthy eating. Both segments have a very favourable disposition towards fish consumption, which would fit with their focus to either stay healthy (positive health enthusiasts) or improve their current health status (health strivers). Health uninvolved consumers do not care strongly about health in general; though attach high importance to eating healthily.     

Trust as Networking Knowledge: Precedents from Australia

Trust, rather than being simply a resource for establishing collaborative relationships between organizations, is an essential component of their constitution. At base, trust involves interpersonal relations of a specific type. These are relations where there is sufficient probability that a person or organization with whom one is in contact will perform an action that is beneficial, or at least not detrimental, for one to consider engaging in some form of cooperation with this person or organization in the future. Trust establishes situations in which participants in collaboration have a long-term and recurrent relationship. Where trust exists, organizations are more willing to collaborate with other organizations on a more reciprocal basis. Trust is especially important when collaboration takes place between competitors because the risk of opportunistic behaviour is higher. Where organizations share resources and information openly with other participants they will seek to reduce opportunistic behaviour through the mutual understanding and goodwill of parties. However, trust is not static; it is a dynamic process that evolves according to the development of the relationship, as one in which the more long-term the relationship, the greater the trust. In this paper, we will present the impact of trust on business networks and examine how their members developed knowledge through networking.     

Organisational culture and decision making: a case of consensus management

Abstract
This paper explores how a state-of-the-art concept, organization culture, shapes decision making and consensus generating strategies used in the successful management of product development activities in high technology companies. Engineering development groups interact with many individuals and groups on a wide variety of very comples engineering, manufacturing, marketing and business issues Much uncertainty exists around these issues because information that would allow for a decision to be made is often unknow or unknowable. Trade-offs are made continually resulting in a high degree of interdependence among development groups and others with whom they interact. Achieving a balance between controlling development activities on the on hand, and encouraging creativity and initiative on the other, is a complicated process.
this paper illustrates the role of organizational culture in product development using case material from a very successful US high case material from a very successful US high technology company. 'Consensus management', a major cultural theme at 'DW Enterprises', is a decision making style that involves everyone in the decision making process who might have relevant input. A cultural analysis reveals that the engineers developed specific techniques for generating consensus, and that these related as much to control over participation in product development as to decision making.     

基于商品质量偏好的双边市场定价策略分析

本文研究了双边市场一方用户群体提供商品或服务的质量在垄断市场情形和单归属（接入）寡头垄断市场情形下对双边市场平台定价问题。研究结果表明：在寡头垄断情形下,消费方和厂商的接入费用和其本身对质量的敏感程度及质量成本系数相关,平台具有鼓励符合条件的用户接入平台的动机。在单归属的寡头垄断情形下,平台之间的厂商无质量差异时,平台倾向于定高价以获取由商品质量引起的双边市场的剩余价值,而消费者和厂商均没有提高商品质量的要求和激励;在寡头平台之间的商品或服务质量差距小,质量信息不透明时,优势平台会随着质量差距扩大而提高厂商的接入费用,其消费者的数量也会增多;若质量信息透明,质量劣势平台为了保持市场份额,其价格与另一寡头平台的消费者市场的接入费用差距与质量差距成正比,而在厂商市场的接入费用差距与质量差距成反比。     

Business services: Markets and transactions

Tertiary activities and among them business services represent an increasingly dominant share of GDP. The main purpose of this paper is to show that the concepts and theories which have been developed mainly with reference to industrial, essentially material, activities are not relevant for service, dominantly non-material, activities, more particularly for informational business services. These-the way they operate, the relations between the actors, the processes through which values are created and prices are determined...-are substantially different, and would thus seem to require substantially, or even radically different approaches and theories.     

绿色服装消费心理与行为的调查分析

采用问卷调查的方法调查中国绿色服装消费者的消费意识、消费心理、消费行为特点,通过调查发现绿色服装消费者已经成为不可忽略的新兴消费群体。绿色服装消费意识仍停留在注重“自身健康”的初级阶段,而“环保意识”较为淡漠;消费环境、消费方式以及产品的价格对消费者的绿色服装消费行为具有非常重要的作用。     

Referrals in search markets

This paper compares the equilibrium outcomes in search markets with and without referrals. Although it seems clear that consumers would benefit from referrals, it is not at all clear whether firms would unilaterally provide information about competing offers since such information could encourage consumers to purchase the product elsewhere. In a model of a horizontally differentiated product market with sequential consumer search, we show that valuable referrals can arise in the equilibrium: a firm will give referrals to consumers whose ideal product is sufficiently far away from the firm's offering. We allow firms to price-discriminate among consumers, and consumers to misrepresent their tastes. We found that the equilibrium profits tend to be higher in markets with referrals than in markets without. Consumers tend to be better off in the presence of referrals when search costs are not too low, and under a certain parameter range, referrals lead to a Pareto improvement.     

Inventory investment and sectoral characteristics in some OECD countries

This paper discusses the effects of sectoral structure on the long run macroeconomic inventory behaviour of national economies. Data on 15 OECD countries are included in the analysis, which is based on correlation and cluster analysis methodologies. The study is part of a long-term research project exploring factors influencing the inventory behaviour of national economies.First, we introduce some basic characteristics of macroeconomic inventory formation in the 15 OECD countries. We argue that our previous results on the existence of specific characteristic features of macroeconomic inventory investment are justified, hence it makes sense to study the factors influencing these features. We then examine the contribution of various sectors to the production of in the countries involved and the relationship between sectoral structure and inventory intensity (annual inventory change/Gross Value Added). We find that the high share of agriculture and manufacturing increases inventory intensity, that the increasing share of services has a negative effect and that the role of construction and trade is not obvious. The relatively low stability of the statistical results warns us to be cautious with our judgements. Further, case-by-case analysis would be required to obtain more solid results.     

A robust methodology for setting tariffs

Pricing new or existing services is a challenge in the current state of the communications industry, with new industrial structures, fast technical change and varying degrees of competition and regulation. Basically the industry is newly immature, with few good models for, and little data on, the behaviour of consumers or competitors. In this paper we describe the development of a robust methodology for the determination of prices, able to cater for some of the sources of uncertainty in the real world, such as market behaviour. By robust, we mean the ability to re-use the basic model with relatively little change if, for example, the underlying sub-model of consumer behaviour is changed from cost minimising to risk averse, or the basis of pricing is changed from value to cost.     

Tax-free digital news?

News platforms are struggling. Their printed readership is predominantly old, and their digital product struggles to win the attention of the young. For several decades tax reductions have been used in Europe to increase the circulation of printed newspapers. Would extending these reductions to digital platforms stimulate digital consumption? Using a two-sided pricing model where a print platform and a digital platform compete for multi-homing consumers and advertisers we show that the answer is no. The two-sidedness of the market means that the digital price would increase. Not only would digital circulation decrease but so too would the fraction of consumers that access news from both platforms. Key media policy goals of reach (circulation) and pluralism (multi-homing) would be harmed.     

The informativeness of on-line advertising

Sending general advertisements with inflationary claims may attract additional visitors with whom an advertiser is poorly matched. This is costly when ads are priced per-click because many visitors (clickers) will not purchase. This renders per-click advertising particularly conducive to the transmission of information via ads. The admissibility of information transmission depends not only on advertiser behaviour, but also upon consumers' interpretation of and trust in ads. In less conducive environments, consumers quickly learn to place little stock in the claims they see advertised. This mechanism undermines the ability of advertisers and consumers to communicate under per-impression or per-sale fee structures. Consumers benefit from increased informativeness, but distortions introduced by the market power given to advertisers imply that society may be better-off with no information transmission taking place.     

Estimating consumer preferences and willingness to pay for the underutilised indigenous chicken products

Indigenous chicken serves many functions, which include the provision of meat and eggs for home consumption and income from sales. The purpose of this study was to estimate the consumers’ responsiveness to an increase in prices of the indigenous chicken products and how much they are willing to pay for them in the market. The survey was conducted in the selected three regions of Kenya. A total of 930 respondents were interviewed both in the urban and rural areas. Contingent valuation experiment was used in empirical data collection. The two-step Heckman selection model was utilised to analyse consumers decisions and the amount they were willing to pay. The study results revealed that consumers are willing to pay 23.26% per kg more for indigenous chicken meat and 41.53% for eggs. Socioeconomic factors like age, income, education and family size significantly determines consumers’ willingness to pay. Other important factors include the indigenous chicken meat substitutes’ prices, attributes like taste/flavour and the product’s form on purchase. The yolk colour and size of eggs determined the consumers’ willingness to pay. Preferences for indigenous chicken products were found to be high. This information will assist in understanding both the urban and rural consumer’s behaviour. Therefore, useful for the indigenous chicken producers, breeders, marketers and policy makers in developing efficient production and marketing strategies. This would also provide a means of improving food security and livelihoods of the rural poor indigenous chicken farmers.     

The implications of heterogeneous habit in consumer beverage purchases on soda and sin taxes

In this article, we study the heterogeneity of habit strength in households’ demand for regular carbonated sweetened beverages (CSBs) and beer in the United States. A demand model that nests a smooth transition function is used to describe habit-based consumption patterns, revealing heterogeneous strengths of habits among households. We find that more habitual consumers, those with a strong preference for a particular product, are not as sensitive to price or expenditure as the aggregate population. This finding is further supported by simulations of the potential effects of soda and beer taxes. We find the aggregate response to soda and beer taxes is smaller than when the influence of habit is assumed to be homogeneous.     

Mobile-only consumers arise from heterogeneous valuation of fixed services

Mobile-only users are usually perceived as a consequence of fixed-mobile substitution. This study uses a unique dataset based on a survey in France, combined with interviewee's telecommunications billing data, to reveal heterogeneous consumer preferences for fixed services. With the same mixed logit model we estimate the willingness to pay (WTP) for fixed communications services and fixed-mobile relationship. Results show a very large heterogeneity of WTP for fixed services among consumers. In addition, we show that fixed and mobile data are complement for all consumers. Mobile-only consumers have a much lower but non-zero WTP, and higher price sensitivity compared to fixed-mobile consumers. Consequently, an increase in the fixed offer price would reduce the demand for fixed service. Heterogeneous preferences for fixed services constitute an alternative explanation for the existence of mobile-only users, despite the complementary nature of fixed and mobile broadband. Counter-factual simulations show that the share of mobile-only could also be driven by the way to subsidize mobile handset. For instance, making the handset subsidy only available to fixed-mobile quadruple play subscribers could reduce the share of mobile-only by half.     

Growth strategies for service firms

Two characteristics of services—intangibility of the offering and simultaneity of production and consumption—have important implications for strategic planning. Four of these implications are described. Life cycle, experience, and market share, which are the usual determinants of profitability that provide guides for strategic planning are not easily applied to the service firm. Therefore growth strategies need to be revised. In its second part the paper suggests alternative growth strategy paths for service firms. It brings forward three main remarks. First, the service firm should not overuse its delivery system and its image by attempting to serve the needs of too many sociodemographic segments. Second, service development and concentric diversification are not sequential choices; the latter is not so distant from the former as may be commonly perceived. Third, expansion to out-of-country markets represents a risk discontinuity; it should be approached by service firms with considerable flexibility and willingness to interact with different cultures.     

Who is governing whom? Executives,governance, and the structure of generosity in large U.S. firms

We examine how organizational structure influences strategies over which corporate leaders have significant discretion. Corporate philanthropy is a strategic activity commonly managed through a specific, differentiated organizational structure—the corporate foundation—that formalizes and constrains the influence of individual senior managers and directors on corporate strategy. Our analysis of Fortune 500 firms from 1996 to 2006 shows that characteristics of senior management and directors affect corporate philanthropic contributions. We also find that organizational structure constrains the philanthropic influence of board members, but not of senior managers, a result contrary to what existing theory would predict. We discuss how these findings advance understanding of how organizational structure and corporate leadership interact and how organizations can more effectively realize the strategic value of corporate social responsibility activities.     

Metasearch and market concentration

Competing intermediaries search on behalf of consumers among a large number of horizontally differentiated sellers. Consumers either pick the best deal offered by an intermediary, or compare the intermediaries. A higher number of intermediaries has the direct effect of decreasing their search effort. Hence, if an exogenous share of consumers do not compare, more competition hurts them. More competition however also increases the incentives for consumers to compare. A higher share of informed consumers in turn increases the search effort of intermediaries. If consumers are ex-ante identical and rationally choose whether to become informed, the total effect of a higher number of intermediaries is to make each of them (weakly) choosier. Moreover, it always decreases the price offered by sellers. Allowing intermediaries to bias their advice by making sponsored links prominent has a similar effect of making all consumers better off in expectation.     

Investor reactions to food safety incidents: Evidence from the Chinese milk industry

Using a natural experiment in the Chinese milk industry as background, this paper investigates the reactions of individual and institutional investors to food safety incidents. By classifying firms as either honest or dishonest, we find that: First, honest firms significantly outperform dishonest ones and receive more investment flow. Second, individual investors react to incidents more negatively and intensely, especially toward dishonest firms, compared with institutional investors. This study offers important policy implications: First, our findings directly suggest that the government should enact appropriate policies to strengthen food safety and protect consumers’ health. Second, the government should implement efficient mechanisms to strengthen firms’ incentives to participate in social responsibility activities. Third, having institutional investors as corporate monitors is not a sufficient substitute for legal penalties.
