This study extends a knowledge‐based theory of opportunity discovery to innovation creation using degree of radicalness. Findings from a sample of 166 founders of new technology ventures in university incubators suggest that asymmetries in knowledge acquisition during early venture development are vital to innovation creation. Innovation radicalness was positively associated with acquiring knowledge of customer problems and markets. However, acquiring knowledge of ways to serve markets was negatively associated with innovation radicalness. This suggests a counterintuitive conclusion—the less technology entrepreneurs know about comparable offerings in the market and how to development them, the greater their chances of creating breakthrough innovations. 相似文献

Models that assume bonds denominated in different currencies are perfect substitutes can not explain certain empirical puzzles: the exchange rate volatility puzzle is that these models can not explain the observed volatility in real and nominal exchange rates; the Backus-Smith puzzle is that these models can not explain the observed low correlation between real exchange rates and the ratio of home to foreign consumption; the Backus-Kehoe-Kydland puzzle is that these models can not explain the observed low correlation between home and foreign consumption; and finally, the uncovered interest parity puzzle is that these models can not explain the observed deviations from that parity. These long standing puzzles make the models harder to defend. In this paper, we present a symmetric two country portfolio balance model in which home and foreign bonds are imperfect substitutes for money in each country’s transactions technology; this of course makes home and foreign bonds imperfect substitutes for each other. Our calibrated model is capable of addressing the Backus-Smith puzzle and the Backus-Kehoe-Kydland puzzle. It does not fully resolve the exchange rate volatility puzzle, but it makes some headway. And finally it generates deviations from uncovered interest parity, though by some estimates these deviations are not large enough to be consistent with the data. 相似文献

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models.
This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers.
However, it is typical in many of these models to use iceberg transport costs as a general form of trade barriers that can
be interchangeable with ad valorem tariffs. I show that this is not always an appropriate conclusion. Specifically, I illustrate
that profit for an exporter is more elastic in response to tariffs than iceberg transport costs, which affects the entry/exit
decision of firms. This has implications for welfare analysis and empirical specifications. 相似文献

In order to live and maintain life, people require some amount of shelter as protection against nature's elements. This paper investigates minimum areas required for shelter. To this end, standards of floor space for households consisting of one to five persons and available from the World Wide Web were obtained for locations in the United States, Canada, Scotland, England, Denmark, India, Hong Kong, Thailand and refugee camps. While some variation exists among regions, particularly for larger households, plotted data indicate a convergence to a minimum requirement of about 140 square feet for single-person households 相似文献

Traditional cointegration tests do not provide strong evidence of convergence between EU countries. In this study, fractional cointegration analysis is used to test for convergence between EU members. Fractional cointegration between inflation and between long-term interest rates is found. The results indicate that there is nominal convergence, but that the equilibrium errors display long memory. Fractional cointegration analysis gives no evidence of real convergence in output. 相似文献

The coordination required to successfully implement supply chain initiatives suggest that supply chain management change processes may possess some unique characteristics. Yet, empirical studies are scarce to support this logic. Using an empirical design and data obtained from managers, and drawing largely from Lewin's change process conceptualization, this study compares the process of supply chain management change to non‐supply chain management change. Further investigation into monitoring and control of supply chain management change is advised. 相似文献

The purpose of this paper is to invoke a Foucauldian framework in order to re-think the development of community-based tourism by focusing on the relationship between intermediaries and rural and isolated area communities in Papua New Guinea. Foucault's concepts of power/knowledge and governmentality provide a 'way of thinking' about this relationship that challenges the dominant discourse of the tourism industry. To further elaborate these alternative concepts, the researchers lead a discussion through a number of areas that impact on the development of community-based tourism. These include the introduction of western models of management and their ability to undermine traditional forms of knowledge, the conceptualisation of the tourist destination as interactive space, and a critique of the tourism industry through poststructuralist feminist theory. From these perspectives community-based tourism or ecotourism suggests a symbolic or mutual relationship where the tourist is not given central priority but becomes an equal part of the system. 相似文献
