Entrepreneurship is commonly held to be a vital force in the US and other economies. Yet, little is known regarding the efficacy of entrepreneurial efforts developed in one country but attempted elsewhere. In response to calls for testable theoretical models, scholars have begun to investigate empirically the attendant phenomena associated with the venture development process. This article describes efforts to test in another nation a nine-stage entrepreneurial process model of venture development derived and validated in the USA. While some development stages appear to exist similarly across borders, others may not be present. Further, the sequence of stages in the US-derived model may differ when compared internationally.  相似文献

Individuals make decisions about whether innovations are adopted and transferred to new uses or locations. This Paper argues that relational competence Is critical for innovation management and technology transfer and that personal communication, formal and informal, is the core component in such competence. It shows how “close ties” and communication are critical to innovation, particularly given the changing nature and role of technolop management in the context o f rapidly increasing globalization. This is illustrated with reference to the communication in he mindset and practice of technology partnering in Australia's participation in the aerospace and telecommunications industries.  相似文献

The state of the nation’s infrastructure is the subject of widespread discussion and comment because it is thought to include many deteriorating and unsafe bridges. Ever since the terrorist attacks of 9/11, there has been increasing concern over the extent to which an attack on infrastructure could result in serious economic disruption. This research develops a model to analyze the economic consequences of an attack on a major element of the highway network. We add a freight network to a national multiregional economic impact model and make freight traffic flows endogenous. The use of a sub-national interstate model recognizes that most infrastructure planning is at the state level and most political leaders’ interest is local. We base our approach on the National Interstate Economic Model (NIEMO) and refer to an elaboration that we name Transportation network and the National Interstate Economic Model (TransNIEMO). The new model enables us to study the state-specific and industry-specific economic impacts of some significant changes in the nature of highway freight movements. We tested the model for selected freight movements in and out of California. The results are entirely plausible and encourage us to elaborate and test the model for hypothetical disruptions of freight traffic throughout the US.  相似文献

Environmental multi-regional input–output (MRIO) models require large amounts of data that all have their specific uncertainties. This paper presents a sensitivity and uncertainty analysis in order to gain an understanding of the directions in which efforts should be made to reduce these uncertainties. The analyses were carried out for an MRIO model to calculate the Dutch carbon footprint. A sensitivity analysis of the technical coefficients showed that changes in the coefficients in the domestic blocks and in the Dutch import blocks had the largest effects on the calculated footprint. The uncertainty analysis consisting of a Monte Carlo simulation based on probability distributions around the model coefficients showed a relatively low degree of uncertainty in the total Dutch carbon footprint; uncertainties in the carbon emissions allocated to regions, sectors and products were larger. Both analyses showed that, in certain cases, it is justified to apply a partial MRIO analysis.  相似文献

It is well known that the right location of shopping centres is of paramount importance. Unless stores succeed in attracting their own clientele, they rely to a large extent on the impulse behaviour of shoppers. To evaluate alternative locations, models of pedestrian behaviour may be useful. Modern technologies such as GPS and RFID offer new possibilities providing data on routes and stops, which are required as input for such models. An automatic interpretation of GPS tracers with respect to the activities being conducted could enhance the applicability of such technologies to retail management applications. This paper reviews this rapidly growing literature, and shows how automatic data imputation can be established by using Bayesian belief networks and how GPS traces can be fused with land use data of retail location.  相似文献

Many potential benefits of foreign expansion have been identified in the literature, yet empirical support that multinational firms perform better than domestic firms is mixed. This paper takes a longitudinal perspective and argues that how much a firm benefits from having foreign subsidiaries depends on its process of internationalization. We argue that a firm's capacity to absorb expansion is subject to constraints: some expansion patterns increase profitability less than others, owing to diseconomies of time compression. We hypothesize that the speed of internationalization, the spread of the geographical and product markets entered, and the irregularity of the expansion pattern negatively moderate a firm's increase in profitability resulting from international expansion. Model estimations based on panel data raised strong support for these predictions. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Pricing behaviour in open economies is examined by adapting Kalecki's analysis of pricing in closed economies. The parameters of the resulting pricing equation are estimated using data for a sample of Australian manufacturing industries. These estimates are then used to calculate measures reflecting the degree of monopoly for an open economy, which are compared with the ratio of aggregate proceeds to aggregate direct costs as a measure reflecting the degree of monopoly for a closed economy.  相似文献
