The paper hypothesizes that diversification by firms based in the pharmaceutical industry during the 1977-86 time period was primarily undertaken to reduce the risks associated with being dependent upon a technologically dynamic environment. Consistent with this non-efficiency motive for diversification, declining economic performance is predicted. A longitudinal empirical analysis provides support for these propositions.  相似文献

A bstract .   Even the most passionate defenders of free trade, such as Mises and Rothbard, claim that trade cannot occur under conditions of strict homogeneity of land, labor, and capital. We show that specialization, trade, and the division of labor can emerge even when resources are initially homogenous, due to "natural heterogeneity," economies of scale, and learning.  相似文献

Environmental Innovations in Small and Medium Sized Enterprises   总被引:1,自引:0,他引:1  
Supporting and accelerating the adoption and diffusion of environmental innovations amongst small and medium sized enterprises (SMEs) is a major challenge to environmental policy makers. Research suggests that whilst SMEs possess high flexibility, their innovative capacity may be limited to incremental changes within their existing technology system and network. Twenty case studies examining the innovation adoption process in SMEs in four sectors and in five countries within the ENVIS project (commissioned by the EU) revealed great variety in factors driving this process. Findings indicate that this variation can be attributed to the character of the environmental innovation, the specific business opportunity, the regulatory setting and pressure experienced by the sector. Based on these findings an analytical framework is suggested, whereby the environmental innovative capability of SMEs is conceived as the result of an interplay between the competencies, the network relations and the strategic orientation of the company (the 'dynamic triangle'). This indicates that policy to support SME's adoption of environmental innovations has to take an integrated form, i.e. addressing and developing competence, networks and strategic orientation of SMEs simultaneously whilst remaining systemic and context sensitive.  相似文献

We analyze the empirical properties of the volatilityimplied in options on the 13-week US Treasury bill rate. These options havenot been studied previously. It is shown that a European style put optionon the interest rate is equivalent to a call option on a zero-coupon bond.We apply the LIBOR market model and conduct a battery of validity tests tocompare three different volatility specifications: contact, affine, and exponentialvolatility. It appears that the additional parameter in the affine and theexponential volatility function is not justified. Overall, the LIBOR marketmodel fares well in describing these options.  相似文献

We examine the impact of monetary policy on the S&P 500 using intraday data. The analysis shows an economically and statistically significant relationship between S&P 500 intraday returns and changes in the Fed funds target rate. The significance and magnitude of the response is dependent on whether the change was expected or unexpected. An expected change in the Fed funds target rate has no impact on prices in the broad equity market; however, an unexpected change of 25 basis points in the Fed funds target rate results in an approximate 48 basis points decline in the broad equity market’s return. The speed of these market reactions is rapid with the equity market reaching a new equilibrium within 15 minutes.

This paper introduces the Theory of Trying to complaining behaviour, and argues that complaining intentions can be explained by the model. Moreover, we model propensity to self‐reference (SR) as a moderating variable, and suggest that the effects of the causes to complaining intentions depend on the SR‐level held by consumers. A sample of undergraduate business students participated in the study, where the goal was to get a better understanding of complaining intentions. Our study provides new and additional insights in the drivers of complaining by also taking dispositional personality differences into consideration. The results demonstrate that boundary conditions for main‐effect models like the theory of trying can be fruitfully addressed through the notion of individual differences. The research documented that customers' propensity to complain systematically differed as a function of their level of self‐referencing. This is both good and bad news to managers. The good news is that a proportion of the customers rely less on their previous experiences in the complaining domain when they form intentions to complain. The bad news is that some others do. The obstacle is that managers cannot tell by the look if they are talking to an individual with high or low propensity to self‐reference. As the customer base contains both types case could be taken in designing marketing communication campaigns that target the groups differently.  相似文献

Drawing upon the corporate social responsibility literature, we investigate the moderating effects of the natural environment and the stage of an organization's life cycle on the market orientation to firm innovativeness relationship. Through 229 owners or chief executive officer respondents, our results establish evidence of (1) a positive linkage between market orientation and firm innovativeness; (2) natural environmental policy positively moderating the market orientation to firm innovativeness relationship; and (3) organizational life cycle negatively moderating market orientation to innovativeness. Our findings suggest ventures characterized as being early in the organizational life cycle are more likely to have a positive environmental policy toward the natural environment leading to a competitive advantage through firm innovativeness.  相似文献

The innovation value chain   总被引:17,自引:0,他引:17  
The challenges of coming up with fresh ideas and realizing profits from them are different for every company. One firm may excel at finding good ideas but may have weak systems for bringing them to market. Another organization may have a terrific process for funding and rolling out new products and services but a shortage of concepts to develop. In this article, Hansen and Birkinshaw caution executives against using the latest and greatest innovation approaches and tools without understanding the unique deficiencies in their companies' innovation systems. They offer a framework for evaluating innovation performance: the innovation value chain. It comprises the three main phases of innovation (idea generation, conversion, and diffusion) as well as the critical activities performed during those phases (looking for ideas inside your unit; looking for them in other units; looking for them externally; selecting ideas; funding them; and promoting and spreading ideas companywide). Using this framework, managers get an end-to-end view of their innovation efforts. They can pinpoint their weakest links and tailor innovation best practices appropriately to strengthen those links. Companies typically succumb to one of three broad "weakest-link" scenarios. They are idea poor, conversion poor, or diffusion poor. The article looks at the ways smart companies - including Intuit, P&G, Sara Lee, Shell, and Siemens- modify the best innovation practices and apply them to address those organizations' individual needs and flaws. The authors warn that adopting the chain-based view of innovation requires new measures of what can be delivered by each link in the chain. The approach also entails new roles for employees "external scouts" and "internal evangelists," for example. Indeed, in their search for new hires, companies should seek out those candidates who can help address particular weaknesses in the innovation value chain.  相似文献
