In environments with expected utility, it has long been established that speculative trade cannot occur and that the value of public information is negative in economies with risk-sharing and no aggregate uncertainty. We show that these results are still true even if we relax expected utility, so that either Dynamic Consistency (DC) or Consequentialism is violated. We characterize no speculative trade in terms of a weakening of DC and find that Consequentialism is not required. Moreover, we show that a weakening of both DC and Consequentialism is sufficient for the value of public information to be negative. We therefore generalize these important results for convex preferences which contain several classes of ambiguity averse preferences. 相似文献

The paper investigates empirically the decision of firms to adopt ‘Advanced Manufacturing Technologies’ (AMT) based on a comprehensive specification of a ‘rank model’ of technology adoption using firm-level data for Swiss manufacturing. The explanatory variables include numerous dimensions of (anticipated) benefits from and costs of technology adoption allowing for uncertainty as well as for information and adjustment costs. Moreover, the effect of complementarities between various functional groups of AMT (design, fabrication, communication, etc.) as well as of learning from the use of previous technology vintages within such functional groups is analyzed, Finally, the size-dependence of the adoption decision is studied in detail. The model yields a quite robust pattern of explanation across estimates with different adoption variables (time period of introduction of AMT, intensity of use of AMT, etc.) with plausible differences of the results based on the alternative adoption measures used. 相似文献

We explore corporate environmental strategy over time, investigating the patterns of evolving environmental investment decisions. Longitudinal case studies provide evidence that environmental strategy evolves through a feedback process, wherein outcomes of earlier decisions have an impact on subsequent decisions. Specifically, positive feedback from outcomes like innovation triggers higher goals, enhancing the undertaking of advanced investments, whereas negative feedback from outcomes, such as increased costs, decelerates the adoption of further investments. The study points to an emergent view of environmental strategy, where capabilities that are gradually developed in concomitance with environmental outcomes lead to an upgrading of environmental goals, thus triggering the feedback process. The process eventually culminates in higher levels of environmental conduct, being more and more integrated with business strategy and competitive advantage. Managers' values and environmental attitudes influence environmental decisions and actions, affecting the acceleration of the feedback process and the magnitude of responses. Managerial implications are discussed. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment 相似文献

While previous studies on mergers and acquisitions (M&As) mostly relied on large firms, our study is based on a sample that includes all Swiss M&As that took place in the period 2006–2008, mostly of which have been SMEs. We investigate the firm characteristics that determine the innovation and economic performance of M&As. The performance measures are based on firms’ assessments. These measures are regressed on a series of possible determining factors as postulated in existing theoretical and empirical literature. M&A performance is primarily affected by specific M&A characteristics, but not by general market characteristics such as demand development or competition conditions. Rather astonishingly, it is also not affected by firm characteristics such as capital intensity, human capital endowment and firm size. There is an interesting exception: innovation activities. This means that, with the remarkable exception of innovation activities, the level of M&A performance is determined primarily by factors of the M&A process itself. 相似文献

There is a large literature showing that unemployment reduces people's well‐being. Yet little is known about the reverse possibility, namely that well‐being itself may influence unemployment propensity. Understanding the potentials of human well‐being in relation to unemployment is important as many developed countries are currently facing high unemployment rates. As well‐being is likely to be endogenous, we use British panel data and implement Lewbel's novel empirical approach for identification. We show that higher well‐being implies a negative causal effect on the probability of being unemployed. The result holds for two very different well‐being measures: life satisfaction and a 12‐item scale of mental health. As such, it provides new empirical evidence on the causal link between well‐being and unemployment propensity. (JEL D03, I31) 相似文献

The existing literature on R&D networks has focused on networks among firms who compete in the product market (downstream networks). This article develops the literature by casting the analysis in the context of a vertically related industry, where both downstream firms and their upstream suppliers can form horizontal R&D networks. 相似文献

【摩根士丹利8月25日】2月份我们曾论证说,中国将打破“奥运魔咒”（Olympic Curse）。虽然我们仍然坚持此观点,但另一方面也认为,奥运会后,中国存在出现“增长恐慌”（growth scare）的风险。即使这次经济减速非常和缓,也很有可能加重投资者的不安,从而对亚洲市场产生明显影响。鉴于此,我们对日本之外亚洲（AXJ）货币的态度更加悲观。 相似文献

We examine the use of subsidies to research and development (R&D) in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers, but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production; however, it does not lead to the equalization of per firm output and therefore to an efficient distribution of production costs. We also find that privatization of the public firm reduces R&D activity and welfare in the duopoly market. This result stands even when optimal R&D subsidies are provided. 相似文献

This paper empirically evaluates the uncertainty of forecasts. It does so using the 1001 series of the M-Competition. The study indicates that although, in model fitting the percentage of observations outside the confidence intervals is close to that postulated theoretically, this is not true for forecasting. In the latter case the percentage of observations outside the confidence intervals is much higher than that postulated theoretically. This is so for the great majority of series, forecasting horizonts, and methods. In addition to evaluating the extent of uncertainty, we provide tables to help users to construct more realistic confidence intervals for their forecasts. 相似文献
