In this article, we discuss a dilemma consisting of the market-oriented perspective of users of medical technology versus the long-term technology foresight perspective. The context of medical technology is interesting, because we have to cope with complex future-oriented multi-level and multi-actor strategic decision making. In order to deal with this dilemma we suggest combining the results of a (group) expert opinion forecasting approach with a more market-oriented scenario-approach. More specifically, we use the results of the Delphi-technique as the main input for the development of various capacity (Market-based) scenarios. We exemplify this approach by a real life example directed at the future of imaging techniques for cancer care in The Netherlands and focus on a set of scenarios that deal with the application of the MRI-technique in the period 2005–2015. The Delphi-panel's expectations with respect to imaging technology representing the technological forecasts, combined with other relevant developments (such as demographic and epidemiological developments) are translated into alternative inputs for assumptions of the scenario-model. This model is basic to the future projections in terms of needed MRI-scanners, manpower and investments. We argue that the results provide motivation to continue to explore the methodological interesting area of innovation, aligning the market-oriented perspective of users of (medical) technology with the long-term technology forecasting perspective. 相似文献

This paper is concerned with how firms in a project‐based industry cooperate in technological innovation projects in the construction industry. The main focus of the paper is on the sharing of capabilities in cooperative innovation projects and how these cooperations are governed. A knowledge‐based perspective is applied, and four cooperative innovation projects in the construction industry are compared. Based on the case studies, a set of propositions is defined. First, a cooperation aimed at a mutual strategic benefit in mutually gaining access to the knowledge bases of the involved firms, while maintaining their own differentiated knowledge base, can result in more stable and long term relationships with mutual trust between the cooperating firms. Second, in a cooperation aimed at a mutual strategic benefit in mutually gaining access to the knowledge bases of the involved firms, partners not only gain access to each other's technological capabilities but also develop and share knowledge about organizational aspects and market situations and gain knowledge about the way of working of the partner firm. Third, in a cooperation aimed at mutual strategic benefit in mutually gaining access to the knowledge bases of the involved firms, noncodifiability of the capabilities is conditional to create a win–win situation. And fourth, cooperation aimed at a mutual strategic benefit in mutually gaining access to the knowledge bases of the involved firms is based on mutual competence and intentional trust as its main governance mechanism, whereas contracting between market parties aimed at knowledge–output transactions is represented by limited trust and arms' length (contractual) relationships as its main governance mechanism. 相似文献

To date, research on new product pricing has predominantly been approached as a choice between market skimming and penetration pricing. Despite calls for research that addresses other complexities in new product pricing, empirical research responding to these calls remains scarce. This paper examines three managerial price‐setting practices for new products, i.e., value‐informed, competition‐informed, and cost‐informed pricing. By engaging in these practices, managers can develop and compare quantifications in order to attain an introduction price for the product. The authors draw on consumer price perception literature, Monroe's pricing discretion model, and numerical cognition literature to develop hypotheses about the impact of price‐setting practices on new product market performance and price level. By studying the effects on market performance and price level, the paper provides insights that may help explain the growth of new products and address the problems of underpricing. The hypotheses are tested in a management survey of 144 production and service companies. The results indicate which pricing practices are superior for the achievement of either higher market performance or higher prices in specific product and market conditions. Whereas value‐informed pricing has an unambiguous positive impact on relative price level and market performance, the results also suggest that in many cases engaging in value‐informed pricing is not enough. The effects of cost‐informed and competition‐informed pricing may differ depending upon the objective (market performance or higher prices), product conditions (product advantage and relative product costs), and market condition (competitive intensity). Engaging in inappropriate pricing practices leads to a decline in new product performance. Moreover, bad pricing practices make the positive effect of product advantage on the outcome variables disappear. The latter finding suggests that companies can jeopardize their efforts and investments in the new product development process if they engage in the wrong price‐setting practices. The findings imply that managers should consider different factors in new product pricing. First, when launching a new product, they should determine their explicit pricing objective, either stressing market performance or a higher price level. To determine the most appropriate pricing practices, however, they should next assess their situation in terms of product advantage, relative product costs, and competitive intensity. Together with the pricing objective, these conditions determine the best pricing practice. On a higher level, the findings imply that companies should invest in knowledge development in order to engage in the appropriate pricing practices for each product launch. 相似文献

In neo-classical welfare economics efficiency and equity are strictly separated. The emergence of New Institutional Economics (NIE) broadens the perspective by focusing on the implications of opportunist behaviour. In NIE emphasis is put on institutional arrangements that improve efficiency. The introduction of opportunist behaviour points at the more general problem of cooperation. As can be illustrated by invoking the Prisoners' Dilemma, cooperation may improve efficiency. Therefore, social norms matter and the question arises how they evolve. Evolutionary game theory shows how economic success may change behavioural dispositions to honesty or dishonesty. On a less abstract level one can investigate whether or not the market system fosters nice social traits. Apart from the approach chosen, the main message is that economics and ethics are strongly intertwined. 相似文献

One aspect of the development of e-market services for the facilitation of business-to-business electronic commerce concerns the provision of automated support for contract performance assessment. Assessing the parties' performance of an agreement, once it comes into force, requires reasoning with the contract terms (obligations, rights, powers and other legal relations that obtain between parties) as parties go about conducting their business exchange, sometimes complying and sometimes deviating from their pre-agreed prescribed behaviour. Compliance with prescribed behaviour is typically evaluated individually by each partner to an agreement and where parties' views differ, disputes arise that require some form of resolution.In this paper we present a simple architecture for an e-market, where an artificial (controller) agent undertakes such resolution. The controller's decision-making is informed by the agreement and each party's view of whether its own and the counter-party's behaviour comply with it. Thus, the controller forms an opinion on the basis of such evidence (and possible additional recommendations from agents representing the parties), in similar spirit to a (human) judge's process of reasoning in arriving at his ruling. We consider this as a belief formation problem and explore the potential of using subjective reasoning to represent an individual's (possibly partial) views and to reason about their joint conflict and consensus formation. We comment on the relation of such belief formation on the establishment of trust between partners to an agreement and between the latter and the controller of an e-market. 相似文献

In a premium auction, the seller offers some “payback”, called premium, to a set of high bidders at the end of the auction. This paper investigates how the performance of such premium tactics is related to the bidders? risk preferences. We analyze a two-stage English premium auction model with symmetric interdependent values, in which the bidders may be risk averse or risk preferring. Upon establishing the existence and uniqueness of a symmetric equilibrium, we show that the premium causes the expected revenue to increase in the bidders? risk tolerance. A “net-premium effect” is key to this result. 相似文献

The literature measuring the effects of WTO membership on trade flows has produced remarkably diverse results. Rose (2004) reports a wide range of empirical specifications that produce no WTO effects. Tomz et al. (2007) use Rose's data but include de facto WTO membership, to find positive WTO trade effects. Rose (2005) also produced positive WTO trade effects after accounting for the diverse trade effects produced by individual preferential trade agreements (PTAs). When Subramanian and Wei (2007) emphasize general equilibrium trade effects by controlling for multilateral resistance, they find strong WTO trade effects only for industrialized countries. Subramanian and Wei (2007), however, account neither for unobserved heterogeneity among trading partners, nor for differences in trade effects across PTAs (which could inflate WTO estimates). We unify the Rose, Tomz et al., and Subramanian and Wei specifications in one comprehensive approach that minimizes omitted variable bias to show that all specifications produce one consistent result: WTO effects on trade flows are not statistically significant, while PTAs produce strong but uneven trade effects. Extending the gravity model to address specific avenues in which WTO may have affected trade flows, we find that WTO membership boosts trade prior to PTA formation and increases trade among proximate developing countries (at the expense of distant trade). An augmented gravity model that accounts for WTO terms-of-trade theory shows that countries with greater incentives to bargain for tariff reductions before WTO accession experience positive and significant subsequent WTO trade effects. 相似文献

Hedging Pressure Effects in Futures Markets 总被引:2,自引:0,他引:2
We present a simple model implying that futures risk premia depend on both own-market and cross-market hedging pressures. Empirical evidence from 20 futures markets, divided into four groups (financial, agricultural, mineral, and currency) indicates that, after controlling for systematic risk, both the futures own hedging pressure and cross-hedging pressures from within the group significantly affect futures returns. These effects remain significant after controlling for a measure of price pressure. Finally, we show that hedging pressure also contains explanatory power for returns on the underlying asset, as predicted by the model. 相似文献
