In this paper, it is argued that innovation can be the result of a repetitive, multi-actor negotiation process. We present the case of an environment-related product innovation in a large multinational company that emerged as the outcome of a complex interaction process in which numerous external and internal actors negotiated to safeguard their own interests. This negotiation perspective challenges conventional economic views of innovations, in which new products and processes are regarded as exogenous variables, the outcomes of deliberately planned research, or the combination of technology (pushing) and market (pulling) inducements. Instead, innovation may be a non-linear, unpredictable process that involves multiple actors with divergent interests and that leads to outcomes that are collectively acceptable but not necessarily (sub)optimal.  相似文献

We identify the relative importance of changes in the conditional variance of fundamentals (which we call “uncertainty”) and changes in risk aversion in the determination of the term structure, equity prices, and risk premiums. Theoretically, we introduce persistent time-varying uncertainty about the fundamentals in an external habit model. The model matches the dynamics of dividend and consumption growth, including their volatility dynamics and many salient asset market phenomena. While the variation in price–dividend ratios and the equity risk premium is primarily driven by risk aversion, uncertainty plays a large role in the term structure and is the driver of countercyclical volatility of asset returns.  相似文献

Foreign Speculators and Emerging Equity Markets   总被引:30,自引:0,他引:30  
We propose a cross-sectional time-series model to assess the impact of market liberalizations in emerging equity markets on the cost of capital, volatility, beta, and correlation with world market returns. Liberalizations are defined by regulatory changes, the introduction of depositary receipts and country funds, and structural breaks in equity capital flows to the emerging markets. We control for other economic events that might confound the impact of foreign speculators on local equity markets. Across a range of specifications, the cost of capital always decreases after a capital market liberalization with the effect varying between 5 and 75 basis points.  相似文献

Public—Private Partnerships (PPPs) are becoming popular in Europe, but does the reality match the idea of co-operating actors who achieve added value together and share risks? An analysis of three PPPs in the Netherlands suggests that, in practice, PPPs are less ideal than the idea. Partners have difficulty with joint decision-making and organization and tend to revert to traditional forms—by contracting out and by separating responsibilities.  相似文献

We specify and estimate an equilibrium job search model with productivity differences across labour market segments. The model allows for two types of unemployment: frictional unemployment due to search frictions and structural unemployment due to wage floors. Wage floors exist because of high unemployment benefits or binding minimum wages. The productivity distribution is estimated semi-nonparametrically along the lines of Gallant-Nychka, using Hermite series approximation. We decompose the total unemployment rate and we examine the effects of changes in the minimum wage.  相似文献

This research investigates the impact of various factors on ethical behavior of 180 not-for-profit hospital employees. Ethical behavior of peers, ethical behavior of successful managers, and emotional intelligence had a significant positive impact on ethical behavior of respondents. Physicians and hospital employees with political connections within the organization were significantly less ethical than other employees. The results have many implications for researchers and healthcare practitioners.  相似文献

The martingale hypothesis for futures prices is investigated using a nonparametric approach where it is assumed that the expected futures returns depend (nonparametrically) on a linear combination of predictors. We first collapse the predictors into a single‐index variable where the weights are identified up to scale, using the average derivative estimator proposed by T. Stoker (1986). We then use the Nadaraya–Watson kernel estimator to calculate (and visually depict) the relationship between the estimated index and the expected futures returns. We discuss implications of this finding for a noninfinitely risk‐averse hedger. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:1040–1065, 2008  相似文献

We investigate the expectations hypotheses of the term structure of interest rates and of the foreign exchange market using vector autoregressive methods for U.S. dollar, Deutsche mark, and British pound interest rates and exchange rates. We examine Wald, Lagrange multiplier, and distance metric tests by iterating on approximate solutions that require only matrix inversions. Bias-corrected, constrained VARs provide Monte Carlo simulations. Wald tests grossly overreject the null, Lagrange multiplier tests slightly underreject, and distance metric tests overreject. A common interpretation emerges from the small sample statistics. The evidence against the expectations hypotheses is much less strong than under asymptotic inference.  相似文献
