This paper discusses how firms develop and use resources across a permeable project boundary and conceptualizes how a project can create value for a focal parent organization. Inspired by ideas on interaction and open innovation, we suggest a framework for analyzing the flow of resources based on the two dimensions; direction, whether the resource starts inside or outside the project, and mode, whether the resources cross the boundary once (uni-directionally) or twice (bi-directionally). The dimensions lead to four situations: Inside-out, Outside-in, Boomerang and Passing on. The framework is based on a single case study of an inter-organizational research project in plant biotechnology in a Swedish context. Through these four situations, the results show that a focal parent organization can create direct, indirect, relational potential and transactional potential value. The complex pattern of value creation in an open network context, raises the challenging question of how to capture the value created.  相似文献

Time series momentum   总被引:1,自引:0,他引:1  
We document significant “time series momentum” in equity index, currency, commodity, and bond futures for each of the 58 liquid instruments we consider. We find persistence in returns for one to 12 months that partially reverses over longer horizons, consistent with sentiment theories of initial under-reaction and delayed over-reaction. A diversified portfolio of time series momentum strategies across all asset classes delivers substantial abnormal returns with little exposure to standard asset pricing factors and performs best during extreme markets. Examining the trading activities of speculators and hedgers, we find that speculators profit from time series momentum at the expense of hedgers.  相似文献

Injuries pose an economic problem of immense proportion to communities in every society. The economic burden from injuries can be quantified through cost-of-injury studies, using techniques adopted from cost-of-illness research. This study explores the feasibility of applying results and methodologies from existing cost-of-injury studies in economic analyses of injury prevention interventions and programmes. The literature on cost-of-injury studies and economic appraisals of injury prevention efforts was examined to elicit studies that calculated injury costs. Studies were accepted for inclusion if they included an analysis of the costs of all injuries occurring in a geographical area (community, region or country) during a specific time period, employed a societal perspective and an incidence-based costing approach and were conducted in industrialized countries. There were 12 studies that met the inclusion criteria. The average total cost per injury case was USD $3536, while the average share of indirect to total cost per injury case was 71%. However, the cost figures showed wide variation across the studies. Based on the limited similarity of findings from the studies, it was concluded that it is not feasible to apply results and methodologies from existing cost-of-injury studies. The cost estimators described in this study could possibly be adapted for use as reference points in economic analyses of existing programmes, but any other uses should be approached with caution. Locally obtained data are needed for reliable economic analyses of injury prevention interventions and programmes.  相似文献

This article is based on a specific situation and competence analysis research project. The objective of the project is to point out possible action areas for improvements and potential competence areas; areas that should be integrated in the company's future strategic work. In the long term, the objective is to develop specific tools that can support a company's decision processes when in and/or outsourcing. The specific tools form the basis for the development of a conceptual framework that may facilitate the work with and the understanding of strategic in and outsourcing.During recent years new theories on SCM, outsourcing, supplier cooperation, etc. have emerged. Each theory has its own specific basis seeking to give solutions to problems concerning how to use and cooperate with suppliers. All theories, however, seek to solve a well-known problem within economic theory. Thus, the issue on division of labour and specialization is well known (Foretag i netwark, Stockholm, Studieforbundet for Naringsliv och Sammhallet, 1982; Joint Venture: theoretische und empirische analyse unter besonderer berücksichtigung der chemischen industrie der schweiz. Verlag Rugger, Germany, 1989). From an economic point of view it is a question of reaching the situation with the lowest production and transaction costs (Handbook of Industrial Organization. Amsterdam, 1989, pp. 135).  相似文献

Multinational corporations (MNCs) need to sense, source, and mobilize knowledge when and where it arises, whether at home, or elsewhere in the world. For this reason, MNCs benefit from employee networks of relationships that span across intraorganizational barriers, allowing for the efficient mobilization of knowledge across boundaries. Yet, which organizational members are more likely to be able to develop these boundary spanning networks? We leverage a unique data set from a large multinational corporation to empirically test a comprehensive model that captures the effect of an employee’s mandate, expertise, and behavioral orientations on her likelihood to span intraorganizational boundaries that manifest themselves in the form of hierarchies, intra-functional domains, and geographic territories. We find that the employees that are more likely to be boundary spanners are those having mandates with a global impact, high levels of expertise, and a collaborative orientation in their networking behaviors. In addition, we find that these effects are stronger for those employees that have large formal workflow networks.  相似文献

Carry     
We apply the concept of carry, which has been studied almost exclusively in currency markets, to any asset. A security’s expected return is decomposed into its “carry,” an ex-ante and model-free characteristic, and its expected price appreciation. Carry predicts returns cross-sectionally and in time series for a host of different asset classes, including global equities, global bonds, commodities, US Treasuries, credit, and options. Carry is not explained by known predictors of returns from these asset classes, and it captures many of these predictors, providing a unifying framework for return predictability. We reject a generalized version of Uncovered Interest Parity and the Expectations Hypothesis in favor of models with varying risk premia, in which carry strategies are commonly exposed to global recession, liquidity, and volatility risks, though none fully explains carry’s premium.  相似文献

This article argues that Danish flexicurity is preconditioned by craft unionism that has historically been predominant in the Danish trade union movement. It is furthermore argued that flexicurity was on the verge to disappear when it became famous in the early 2000s, although yet not completely dead.  相似文献

For many kinds of capital, depreciation rates change systematically with the age of the capital. Consider an example that captures essential aspects of human capital, both regarding its accumulation and its depreciation: a worker obtains knowledge in period 0, then uses this knowledge in production in periods 1 and 2, and thereafter retires. Here, depreciation accelerates: it occurs at a 100% rate after period 2, and at a lower (perhaps zero) rate before that. The present paper analyzes the implications of non-constant depreciation rates for the optimal timing of taxes on capital income. The main finding is that under natural assumptions, the path of tax rates over time must be oscillatory. Oscillatory tax rates are optimal when depreciation rates accelerate with the age of the capital (as in the above example), and provided that the government can commit to the path of future tax rates but cannot apply different tax rates in a given year to different vintages of capital.  相似文献

We study the impact of tax and transfer programs on steady-state allocations in a model with search frictions, an operative labor supply margin, and incomplete markets. In a benchmark model that has indivisible labor and incomplete markets but no trading frictions we show that the aggregate effects of taxes are identical to those in the economy with employment lotteries, though individual employment and asset dynamics can be different. The effect of frictions on the response of aggregate hours to a permanent tax change is highly nonlinear. There is considerable scope for substitution between “voluntary” and “frictional” nonemployment in some situations.  相似文献
