This paper presents a model that introduces in an unbalanced growth framework à la Baumol the hypothesis of an endogenous productivity growth due to a positive externality of the service sector on manufacturing productivity and a learning‐by‐doing process inside both sectors. The model shows that a policy aimed at keeping the ratio between outputs in the two sectors constant in real terms may improve the aggregate productivity performance of the economy, depending on the parameters' values. Then the model derives the dynamics of the intersectoral transfer which is necessary to keep the ratio between outputs constant, and verifies that the amount of the transfer turns out to be always lower than the output of the manufacturing sector, and only asymptotically approaches it. 相似文献

This paper is about shareholder value. We examine whether welfare considerations justify that target and whether competitive markets force firms to pursue it. We also argue that shareholder value is strictly an ill-defined goal. We report evidence from a large sample of listed firms across the world that many managers do not even mention shareholders in their mission statements. However, firms that do disclose a commitment to shareholders seem to perform better in terms of stock price and operating performance. 相似文献

Organizing for Inbound Open Innovation: How External Consultants and a Dedicated R&D Unit Influence Product Innovation Performance 下载免费PDF全文

Firms increasingly acquire technological knowledge from external sources to improve their innovation performance. This strategic approach is known as inbound open innovation. The existing empirical evidence regarding the impact of inbound open innovation on performance, however, is ambiguous. The equivocal results are due to moderating factors that influence a firm's ability to acquire technological knowledge from external sources and to transform it into innovation outputs. This paper focuses on a relevant yet overlooked category of moderating factors: organization of research and development (R&D). It explores two organizational mechanisms: one informal and external‐oriented (involvement of external consultants in R&D activities) and one formalized and internal‐oriented (existence of a dedicated R&D unit), in the acquisition of technological knowledge through R&D outsourcing, a particular contractual form for inbound open innovation. Drawing on a capabilities perspective and using a longitudinal dataset of 841 Spanish manufacturing firms observed over the period 1999–2007, this paper provides a fine‐grained analysis of the moderating effects of the two organizational mechanisms. The involvement of external consultants in R&D activities strengthens the impact of inbound open innovation on innovation performance by increasing marginal benefits of acquiring external technological knowledge through R&D outsourcing. Moreover, it reduces the level of inbound open innovation to which the highest innovation performance corresponds. Instead, the existence of a dedicated R&D unit makes the firm less sensitive to changes in the level of inbound open innovation, by reducing marginal benefits of acquiring external technological knowledge through R&D outsourcing, and increases the level of inbound open innovation to which the highest innovation performance corresponds. The results regarding the role of informal and formalized R&D organizational mechanisms contribute to research on open innovation and absorptive capacity, and also inform managers as to what organizational mechanism is recommended to acquire external technological knowledge, depending on the objectives that the firm pursues. 相似文献

The Country Parks of Hong Kong occupy 40%of the total landmass of Hong Kong,and consists of vast areas of secondary woodlands,scrublands,grasslands,and reservoirs.That vegetation-and the soil underneathsubtract carbon from the atmosphere,which has a market value.The aim of this paper is to estimate the value of that carbon,to assess whether that value would be sufficient to pay for the upkeep of the Country Parks,and to compare that value to the costs of alternative ways to reduce atmospheric carbon dioxide.To do this,we compare the land cover of 1978,1991,1997 and 2004 using remote sensing,and identify the three predominant land covers(woodlands,scrublands,grasslands) .We then estimate the amount and value of the carbon sequestered by the vegetation and soil of the Country Parks,and compare it to the budget available to the Agriculture,Fisheries and Conservation Department to run the Country Parks(HK$234 million in 2009/2010) .We extrapolate our results over 50 years,from 1978 to 2028.We conclude that by 2028 the carbon sequestered would be valued over HK$800 million,but the value of the additional carbon subtracted yearly would only cover approximately 7%of the total budget needed to run the Country Parks.We also conclude that because of the large budget allocated to the Country Parks,alternative methods of carbon sequestration-represented by the EU ETS price of carbon-are much cheaper. 相似文献

The objective of this paper is to derive some integer-majorization results for variable-sum comparisons. We use an axiomatic framework to establish equivalence between several intuitively reasonable conditions. 相似文献

Mobile games are a prime example of a successful mobile application and demonstrate the increasing range of platforms for the media and entertainment industries. Against this convergent background, this paper introduces the basic features of the mobile gaming market and its industrial ecosystem together with its main actors and activities. The focus of the paper lies in the challenges ahead for the evolution of mobile applications into a potentially dominant game platform and the possible disruptions along this road. The deep personal relationships between users and their mobile devices are considered to further explore the link between mobile games, players’ strategies and pending techno-economic developments. The paper concludes with a brief discussion of some policy options to assist with the development of this domain. 相似文献

The Italian National Health Service introduced quad-markets, regionalization, and managerialism in the 1990s. Under quasi-markets, large providers have been separated from purchasers and funded by 'activity'—the quantity, mix, and possibly appropriateness of services provided. Under regionalization, each of Italy's 21 regional governments is able to design its own funding arrangements. The regions have generally been trying to mitigate the effects of quasi-markets and are now increasingly 'governing' them. The system is producing some desirable results, including a shift from ordinary to same-day hospitalizations and a reduction in length of stay. Hospital admissions increased initially, but only where the regions encouraged this. Financial effects are more controversial. 相似文献

We present a model of spatial price discrimination where R&D spillovers are endogenous as they depend on firms' location. We establish that both the distance between locations and R&D efforts are an increasing function of the transportation cost coefficient and show that there is a continuum of cases where firms will choose an intermediate location. The managerial implications from the model are discussed using examples of marketing behavior by Internet retailers. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献
