For their technological sustainability innovations to become successful, entrepreneurs can strategically shape the technological field in which they are involved. The technological innovation systems (TISs) literature has generated valuable insights into the processes which need to be stimulated for the successful development and implementation of innovative sustainability technologies. To explore the applicability of the TIS framework from the perspective of entrepreneurs, we conducted a case study in the Dutch smart grids sector. We found that the TIS framework generally matches the perspectives of entrepreneurs. For its use by entrepreneurs, we suggest a slight adaptation of this framework. The process ‘Market formation’ needs to be divided into processes that are driven by the government and processes that are driven by entrepreneurs. There should be a greater emphasis on collaborative marketing, on changing user behaviour and preferences and on the development of fair and feasible business models.  相似文献

Abstract . The relative fiscal efficacy of using differential assessment as a means of preserving agricultural land is examined. A simple model of land use and land rent determination is developed and tested. An implication is that differential assessment merely delays or retards, but does not prevent, the conversion of land to developed uses. Differential assessment is viewed as a tax expenditure, or special tax reduction, that in essence leases development rights, Landowners are also shown to be overcompensated for the development rights implicitly acquired by the public sector. The fee simple purchase of development rights or regulatory control over the use of development rights can be employed to preserve farm land at a lower fiscal cost.  相似文献

The U.S. Green Building Council offers LEED certification for existing and new neighborhood developments that meet sustainable urban development standards. Features of sustainable urban development have been found to positively affect residential sales prices. We investigate whether the intangible labeling effects of LEED neighborhood certification add a premium to the sales prices of LEED and non‐LEED–certified condos. Using a quasi‐experiment, transaction data from Portland, Oregon, and a spatio‐temporal autoregressive (STAR) model, we find no evidence that the intangible labeling effects of LEED neighborhood certification directly or indirectly affect sales prices. Our results suggest that, contrary to LEED building certification, which we find adds a premium to condo sales prices, the LEED neighborhood label by itself fails to add value for condo buyers. Explanations for our findings include market acceptance, neighborhood delineation issues and the free rider problem as it relates to public goods.  相似文献

International markets are increasingly signaling demand for quality-differentiated coffee, which the Colombian Coffee Growers Federation (FNC) proposed to exploit to identify those regional coffees that would fulfill the requirements to be classified as denomination of origin. The objective of this study was to develop and implement a sound, robust and repeatable approach with and for the FNC to identify regional causal relationships between coffee quality and environmental characteristics as bases for labels of denomination of origin. Environmental differences between coffee-growing areas in the departments of Cauca and Nariño were statistically significant for several characteristics, including the number of dry months, annual precipitation and diurnal temperature range. The dominant varieties (Caturra and Colombia) did not show major differences in quality attributes, and were pooled for the analyses with the environmental data. There are significant differences in biochemical and sensorial product characteristics between the two departments. The spatial patterns in product characteristics exhibit a non-random, regionally-changing structure that is related to those in the environmental data. The generated results provided ample evidence to support the application for regionally-based denominations of origin. Recommendations were derived to help mainstreaming the developed approach and thereby facilitate policy decisions for its use in other geographies and with other crops. Furthermore, the importance of systematic interdisciplinary institutional collaboration for large-scale denomination of origin projects was corroborated for food policy dialogue and decision making. It seems plausible that producers of high-quality products within other commodities are likely to follow the FNC in seeking denomination of origin for their goods. The presented approach is crucial to facilitate policy.  相似文献

The Fire Management Program (FMP) of the Victorian Department of Natural Resources and Environment is responsible for the prevention and suppression of fires on public land in the State of Victoria. This article reports on an economic evaluation of the net benefits of these fire management activities for a representative year. The FMP is calculated to yield high net benefits to Victoria from its investment in fire suppression and prevention, through a reduction in the value of agricultural, capital and forest assets which would otherwise be lost to bushfires.  相似文献

This is a case study of a volunteer programme in a community welfare centre in St Petersburg, Russia. It is suggested that the successful and long‐term activation of its 900 volunteers can be credited to the programme's structural and managerial characteristics. These include: a formal and hierarchical structure and management; clearly defined privileges and obligations; small working groups called ‘brigades’; a comprehensive support system for volunteers and a variety of volunteer opportunities and participation benefits. Advantages and limitations of the programme are discussed, as well as the applicability of some of its principles to other settings. The research demonstrates the importance of contextual and socio‐cultural variables to the debate on the relevance to volunteer work of managerial principles applied with paid employees.

We consider a classical risk model with the possibility of investment and positive interest rate for the riskless bond. The stock price movement is modelled as a geometric Brownian motion, the claim sizes are assumed to have a distribution belonging to a certain subclass of subexponential distributions. In this setting, we study the asymptotic behaviour of the optimal investment strategy under the ruin probability as a risk measure. This problem has been already considered before, but no results were obtained, for instance, for Weibull and Benktander-type-II distributions with certain parameters. We introduce a method which closes this gap.  相似文献

It is predicted that the twenty-first century will be dominated by air transport, both for domestic and international carriage of passengers and cargo. Thus the airport, as a driver of regional growth, is expected to become more than merely a regional gateway. Rather, it will function as city in itself, with living spaces for workers and their families, factories relying on airborne inputs and service industries located around the airport, with major road and rail infrastructure connected to it. However, the ‘aerotropolis’, as this hub for industry and driver of economic development has been called, has not yet been critiqued adequately, especially from a long-term public policy and planning perspective. This article raises concerns about three different dimensions to the aerotropolis regarding its long-term sustainability, viz., energy provision, the security of critical infrastructure and export pathways. In particular, this article argues that air transport will not replace existing components of international economic development. The authors contend that the three dimensions need to be explored in order to arrive at a more balanced view of the aerotropolis and its place in an increasingly complex global future.  相似文献

This paper evaluates the effect of the Rural Capacity Building Project (RCBP), which aimed at promoting growth by strengthening the agricultural service systems in Ethiopia, and by making them more responsive to smallholders’ needs, in particular women farmers. We examine the gender‐differentiated impact of the RCBP using panel data on 1,485 geographically dispersed households in project and control kebeles. We find that women farmers’ access and satisfaction with extension services increased significantly immediately after the start of the project, but that effect did not last into the medium term. The project led to an increase in the adoption of high‐value crop farming, area of land cultivated, and economic participation of household members, benefiting male‐ and female‐headed households equally. Results point to the positive impact of incorporating women's needs and constraints in the design of the agricultural extension system. However, the project was not able to reduce the preexisting gender gap in agricultural outcomes.  相似文献
