The Norwegian agriculture is highly protected and subsidised. The opposite is the case for fisheries and fish farming which suffer from foreign market restrictions. Using a computational general equilibrium model, the gain for Norway of a complete elimination of food subsidies and tariffs is estimated to be in the range of 1.2–2.7 per cent of GDP. Most of this gain stems from domestic farm sector liberalisation. The gain from free market access for seafood is estimated to 4.4 per cent of the seafood export value. Consequently, Norway has much to gain from offering other countries market access for agricultural products. By pursuing such a policy, Norway may also strengthen the case for fisheries and fish farming in trade talks.  相似文献

A model of tenure choice is presented which treats the benefits and costs of homeownership from a theory of finance perspective. The incremental benefits from homeownership over renting housing services are from two sources: protection against rental price risk (a forward transaction in the housing market) and from a possible capital gain from the eventual sale of a house (substitutes for portfolio investment). The cost of these benefits is higher initial outlay on housing, which reduces the funds available for portfolio investments. The comparative statics of this model is presented. It is shown that rental risk and portfolio risk add to the value of homeownership. Since homeownership is a partial substitute for portfolio investment, it is shown that the lower the covariance between portfolio returns and future home prices the more valuable is homeownership. In the presence of differential borrowing opportunities it is shown that the leverage available to housing significantly increases the value of homeownership.  相似文献

Search and Liquidity in Single-Family Housing   总被引:5,自引:0,他引:5  
A two-stage least squares model of housing prices is estimated with data collected from 3358 single-family home transactions. The results provide evidence for an optimal marketing period and indicate that a liquidity premium is priced in single-family home sales. Consistent with the hypothesis derived from economic search models, the model shows higher selling prices for houses having longer expected marketing periods. The model also shows a price premium for houses that sell faster than expectations. This effect supports the concept that liquidity is a value-enhancing characteristic.  相似文献

Initiation of business relationships in service-dominant settings   总被引:1,自引:0,他引:1  
Industrial companies today are becoming increasingly service-oriented and therefore need to shift from selling hardware to valuing services and managing customer relationships. A new and particularly significant challenge for these companies is how to initiate relationships which is an issue that has received surprisingly limited scientific attention. The aim of this study is to develop a conceptualization that explores the dynamics in the relationship initiation process in service-dominant settings. Narratives from three sellers of professional services, augmented with narratives from a buyer's view, form the empirical basis of the study. The dynamics in the relationship initiation process are clarified with three new concepts: status, converter, and inhibitor. The paper concludes with implications of the new conceptualization and suggestions for future research.  相似文献

In this model, two players, who are heterogeneous in information quality, compete with each other with perfect information about the other player's information quality. The less-informed player has an incentive to delay her action in order to gain more information. The more-informed player also intends to delay her action, not through a desire to learn but rather to prevent the less-informed player from gaining information. Hence, if a waiting option is available, both players want to delay their actions and the conflict between the two types of second mover advantage yields a delay race. Although both players can benefit from a delay, the gain from a delay in order to learn is greater than that from a delay intended to prevent the other from learning. Therefore, the cost for a delay plays an important role in characterizing the equilibrium, and if the sequential timing of actions is derived in a pure equilibrium, the leader will be the more-informed player. If a given cost for a delay is sufficiently low, the only equilibrium is a mixed equilibrium. Interestingly, in that equilibrium, the existence of the first-mover advantage from being imitated is also derived.  相似文献

Consumption of food away from home is rapidly growing across the developing world, and will continue to do so as GDP per person grows and food systems evolve. Surprisingly, the majority of household surveys have not kept up with its pace and still collect limited information on it. The implications for poverty and inequality measurement are far from clear, and the direction of the impact cannot be established a priori. This paper exploits rich data on food away from home collected as part of the National Household Survey in Peru, to shed light on the extent to which welfare measures differ depending on whether food away from home is accounted for or not. Peru is a relevant context, with the average Peruvian household spending over a quarter of their food budget on food away from home since 2010. The analysis indicates that failure to account for this consumption has important implications for poverty and inequality measures as well as the understanding of who the poor are. First, accounting for food away from home results in extreme poverty rates that are 18 percent higher and moderate poverty rates that are 16 percent lower. These results are also consistent, in fact more pronounced, with poverty gap and severity measures. Second, consumption inequality measured by the Gini coefficient decreases by 1.3 points when food away from home is included – a significant reduction. Finally, the inclusion of food away from home results in a reclassification of households across poor/non-poor status – 20 percent of the poor are different, resulting in small but significant differences in the profile of the poor in dimensions such as demographics, education, and labor market characteristics. Taken together, the results indicate that a serious rethinking of how to deal with the consumption of food away from home in measuring well-being is urgently needed to properly estimate and understand poverty around the world.  相似文献

The focus of the World Trade Organization is establishing limits on governments’ ability to impose trade barriers in response to producers’ requests for protection. In recent years, however, requests for protection from imports has increasingly come from consumers over issues ranging from animal welfare concerns, employment of child labour, the use of growth hormones, differing environmental standards and GM foods. The current international trade regime is ill-suited to deal with consumer-based protectionism. This paper develops a model that explicitly incorporates consumer concerns into an international trade model and compares the result with the standard treatment. Further, using the model incorporating consumer concerns, a labelling policy for imports is compared to an import embargo. The labelling policy is found to be superior to an embargo. Implications are drawn for future trade negotiations pertaining to sanitary and phytosanitary measures and technical barriers to trade.  相似文献

The model incorporates an infinite series of auctions for identical items (or close substitutes) ordered over time and bidders with unit demand. The participants of each auction are drawn from a dynamic pool, with losing bidders remaining in the pool of potential bidders. The number of bidders in each auction is unobservable. Risk‐neutral, forward‐looking bidders submit bids below valuation. A novel identification and estimation strategy is used to estimate the valuation distribution from an order statistic of the bids. The model is used to evaluate the efficiency of online auctions for a 60GB Apple iPod Video, compared to a perfect‐competition benchmark.  相似文献

This study examines the relationship between a firm's venturing activities and its undertaking of strategic renewal. The study was motivated by some important gaps in the corporate entrepreneurship literature on venturing and renewal. The extant literature has not focused on the different types and dimensions of firms' renewal activities. In particular, discontinuous renewal involving shifts in firms' core businesses is not well understood. Moreover, the conditions that drive firms to undertake strategic renewal have not been examined. For example, it is not known how venturing increases or reduces the benefits of undertaking renewal. This study focuses on a discontinuous form of renewal involving major changes in firms' core businesses and examines firms' external venturing activities that complement their internal development. We examine corporate venture capital (CVC) investments, which are direct minority equity investments made by established companies in privately held ventures. Discontinuous renewal is conceptualized as resulting from a set of related, and often sequential, managerial decisions. The first managerial decision is to initiate growth in a business that is relatively newer or smaller for the organization. The second decision is to move away, or even withdraw completely, from the current core business that enabled prior growth and prosperity for the firm and served as its primary revenue earner. Employing a real options perspective, we argue that CVC investments create growth options in new and existing businesses but do not result in firms' withdrawal from existing businesses. Therefore, we expect CVC activity to be negatively associated with the likelihood of a firm undertaking discontinuous renewal. We also propose that the benefits of withdrawing from existing businesses are even lower, and the costs even higher, for firms in dynamic industries and for firms that possess strong internal capabilities. The predictions of the study are tested using longitudinal data on 477 firms from the 1990 Fortune 500 list for the period 1990–2000. We find support for all our predicted hypotheses. These results help address important limitations in the corporate entrepreneurship literature. The study also contributes to the real options and organizational capabilities literatures.  相似文献

This article explores relationships between designing and making in the work of children within the age range 5–11 when engaged in practical modelling tasks. The notion of the model is explored from the perspective of concrete representations. It is suggested that concrete models may be used as hypotheses from which to test ideas about the nature of the world. From this perspective, models may be seen to provide crucial platforms for learning. A wide range of sources has informed the article, and these embrace ideas on Hypothesis Theory drawn from linguistic research, as well as historical sources which trace the evolution and development of stimuli for model-making activity. A creative basis for modelling is explored such that a conclusion is reached in which design is seen as an expression of the modelling of possibilities.  相似文献

The connection between broadband deployment and economic prosperity in the United States has garnered public attention due to stimulus plan funding authorized in February 2009 for broadband planning and deployment initiatives. The importance of innovation for a nation's economic well-being is fairly well understood. Through a literature survey, this article analyzes the connection between information and communications technologies and economic growth, as well as the connection between broadband and economic growth. There appears to be a positive economic impact from expanded broadband deployment and adoption. However, various research challenges including methodological problems and access to sufficiently granular data have prevented the authors from drawing more definitive conclusions from the US broadband experience. Another finding is the time lag for businesses to effectively exploit innovative broadband applications.  相似文献

Historically speaking, students were judged long before they were marked. The tradition of marking, or scoring, pieces of work students offer for assessment is little more than two centuries old, and was introduced mainly to cope with specific problems arising from the growth in the numbers graduating from universities as the industrial revolution progressed. This paper describes the principles behind the method of Comparative Judgement, and in particular Adaptive Comparative Judgement, a technique borrowed from psychophysics which is able to generate extremely reliable results for educational assessment, and which is based on the kind of holistic evaluation that we assume was the basis for judgement in pre-marking days, and that the users of assessment results expect our assessment schemes to capture.  相似文献

Organizational learning widely is believed to be important to competitive performance of companies. The purpose of this article is to examine how organizations learn from their experiences in new product introductions. Theory suggests that organizations will display a “competency trap” that reduces their ability to learn from organizational experience. Often initial success can cause a firm to rely on a single or a few experiences to develop routines, discounting later experiences. Therefore it is expected that organizations will have trouble learning from experience. The theory was tested by examining all new product introductions in the U.S. shampoo industry from 1974–1987. The dynamic nature of the business—the average brand survives about two years—made this an attractive research venue. Using the econometric technique of survival time modeling, a model was fitted of survival of brands as a function of organizational experience and organizational experience squared. The model also included controls for financial resources available to the firm and the level of first year's advertising. The model confirmed the general hypothesis that firms' brands are less successful the more experience they have. This study interprets this as evidence of a competency trap in new product introductions. The results broadly are supportive of the hypothesis that organizations find it harder to learn from experience as experience grows. Untangling the source of this problem is a goal of further research. For practice, the article suggests caution to brand managers in experienced companies. There is no guarantee that firms grow in their ability to build brands; results here suggest the opposite. Formal reviews of the new product, its process, and its performance by senior managers for lessons learned is desirable. Management of individuals and organizations may facilitate learning from experience. For managing individuals, often product success brings about a reassignment of successful personnel; care should be taken to insure that individuals' learning is captured by the new product organization before reassignment. On the organizational level, formal brand management may be a highly effective method for managing an ongoing stable of long‐lived brands but may be a poor choice in a dynamic market like shampoo. Companies may explore new organizational structures and departments to conceive and to develop new products since the skills required for managing ongoing brands may be different from creating new ones.  相似文献

再论中国地方政府主导型市场经济   总被引:18,自引:3,他引:18  
本文着重研究以强烈扩张冲动为主要特征的中国地方政府主导型市场经济。笔者将企业经营者个人控制权理论运用于地方官员,认为官员个人控制权扩张有三条途径,而中国目前地方官员主要运用横向扩张途径以获得自我晋升。中国地方政府强烈的扩张冲动,不同于西方的地方自治和中外历史上的封建诸侯,而是产生于以下全部的必要条件和充分条件:在中国初期市场经济②的特定条件下,必要条件是地方官员横向扩张个人控制权特别强劲的动力,充分条件是地方资源完全的“内公外私”产权③与公共选择制度两者约束的显著失效。  相似文献

In addition to experimental data, using information collected from farmers is vital to assess the performance of candidate farming technologies. The latter provides the basis for farmers’ assessments and adoption decisions. Using detailed georeferenced plot and household level data from Ethiopia, this paper estimates the impact of a set of sustainability-enhancing agronomic practices on maize yields and implied net maize income with the aid of multinomial endogenous regime-switching regression that corrects for unobserved heterogeneity. The treatments’ effects on yield ranged from 29.5% for the fertilizer-dominant strategy to 88% in the case of fertilizer, maize-legume diversification, and soil and water conservation combinations. Second, while the impacts of the agronomic packages are significant in almost all states of the world, there were considerable heterogeneity effects conditioned on observed rainfall deviations from the historical average with levels effects of up to 92% and heterogeneity effects of 33–64%. The heterogeneous and rainfall-conditioned impacts point to the role of local biophysical modifiers of the impacts of agricultural practices. Investments in context-appropriate adaptation in agricultural research and extension is suggested.  相似文献

This paper analyses the issue of balancing the gains from trade with the risk of pest and disease transference. Two decision frameworks for determining whether or not to permit trade in a potentially invasive species-carrying good are presented. The first considers only the potential production losses resulting from an invasive species entering through a trade pathway, as is prescribed by WTO compliance. The second is a unilateral welfare-maximising approach which considers the consumer gains from trade, the loss of domestic producers’ market share and expected damage from the invasive species. It is shown that these alternative decision frameworks can be reconciled such that they produce the same outcome regarding whether or not trade is to be permitted. The key parameters which influence these decisions are also highlighted.  相似文献

Recent contributions to the literature have resulted in a standard modelling of office markets. The models provide considerable insight into the working of office markets. • Nonetheless, a major difficulty is the use of data for a single city or aggregate data for the U.S. The latter implicitly assumes that model structure is invariant across cities. In this article we test for structural differences in office markets by size class. Rental data from REIS Reports for twenty-one metropolitan areas for the time period 1981 to 1990 are used to model office market behavior. Results suggest market outcomes vary by city size, larger markets are better modelled using standard procedures, and Manhattan behaves quite differently from the other markets.  相似文献

This paper originated from a two-year technological education teacher development project at the Faculty of Education, The University of Western Ontario. The authors searched for an understanding of technology and technological education through traditional scholarly means, i.e., a literature review, and through an action research venture that, it was thought, would reveal the parameters of ‘technology’. The paper, beyond helping to give the authors and the reader a better understanding of what it means to define an elusive concept, serves to give technology educators a conceptual starting point from which to build insight into the elements of their life's work. The function and form of the paper evolved from the project process. They [the function and form] were determined by the nature of and ambiguities associated with technology. The reader is invited, for example, to consider the historical, social, cultural, and philosophical dimensions of technology. Rather than draw parallels about technology from those diverse disciplines, a daunting task, the paper charts a terrain from which investigators who seek a definition of technology and a framework for the subsequent study of technology, might get their bearings. The paper includes approaches to defining technology, a literature review, a comparison of science and technology, and an epilogue. While a definition is offered as part of the epilogue, the larger purpose of the paper is to improve one's understanding of an ubiquitous phenomenon. The central question of the ongoing debate, in Ontario and elsewhere, about the role and direction of technological education, is inherent in the paper and in the mandate of the teacher development project. What is technology and where and in what form does it belong in the curriculum of the schools?  相似文献
