Corporate innovation and the entrepreneurial strategies on which it is based are key challenges at the forefront of executive concerns. In order to establish some factual foundations amid the popular folklore which surrounds corporate innovation today, this study examines the actual factors that influence internal corporate venturing within the realm of a corporate entrepreneurship strategy. Data were collected from 145 internal corporate ventures (early-stage, middle-stage, and established-stage) operating in 72 firms headquartered in the midwestern United States. The results of this study are summarized herein and offer insights regarding some of the key correlates of corporate venturing performance. 相似文献

We demonstrate that Rybczynski's classic comparative statics can be reversed in a Heckscher-Ohlin world when preferences in each country favor the exported commodity. This taste bias has empirical support. An increase in the endowment of a factor of production can lead to an absolute curtailment in the production of the commodity using that factor intensively, and an absolute expansion of the commodity using relatively little of the same factor. This outcome - which we call “Reverse Rybczynski” - implies immiserizing factor growth. We present a simple analytical example that delivers this result with unique pre- and post-growth equilibria. In this example, production occurs within the cone of diversification, such that factor price equalization holds. We also provide general conditions that determine the sign of Rybczynski's comparative statics. 相似文献

ABSTRACT If labor is fairly mobile, as it is in the United States, one would expect that households would move from less desirable areas toward more desirable areas until all areas are equally desirable. The way that areas become equally desirable is through the impact of movers on wages and rents (and possibly endogenous disamenities, such as congestion or pollution). That is, as people move to desirable areas, they will increase the demand for land (raising rents) and increase the supply of labor (lowering wages); in equilibrium, the wage and rent compensation for the niceness of an area reveals, in dollar terms, just how nice the area is. Blomquist, Berger, and Hoehn 1988 demonstrated the empirical importance of such amenity compensation in estimates of the quality-of-life in urban areas. However, those authors were unable to include fringe benefits, which are about 40 percent of explicit wage payments, in their wage compensation. This matters greatly as amenities are seen here to be even more important than previously thought and the regional implications are pronounced, with the West and Southeast looking better when fringe benefits are included and the East North Central and Northeast looking substantially worse. 相似文献

As APICS practitioners, we all must share a common goal. How can we contribute to our company's success? Success can be measured in positive terms of market share, growth, profitability, return on investment, or some combination thereof. Each company must establish its own definition of success. For the purposes of this article, success will be equated to one word that we can all readily identify with: survival. What skills do we need to survive in the marketplace of the next millennium? 相似文献

This paper investigates the impact of individual asset holdings on the probability of leaving unemployment. According to the theory, higher levels of financial wealth will result in higher reservation wages and longer unemployment durations. I estimate the impact of financial assets on the hazard rate, using data for Great Britain. The empirical findings indicate that individual asset holdings affect significantly the escape rate out of unemployment. In particular, negative (positive) levels of wealth increase (reduce) the hazard of leaving unemployment. The size of the impact is, however, rather small. Increasing by 100% the level of wealth of a representative individual, with net wealth and other individual characteristics equal to the sample mean, increases the duration of the unemployment spell by half a week. 相似文献

A possible definition of ill-posedness in statistical estimation is the lack of qualitative robustness. In this sense direct density estimation shares ill-posedness with the more obviously ill-posed indirect density estimation models, of which it is a special case. A general construction pattern for estimators is proposed, based on suitable preconditioning, that works for both direct and indirect density estimation. Special emphasis is on its application to the direct case, where in general it yields delta-sequence estimators. More specifically both kernel and series type estimators are included depending on the choice of preconditioning operator. In particular sinc and other flattop kernel estimators emerge in a natural way. 相似文献

This article develops a mechanism to measure the impact of local content requirements as quantitative restrictions. We compare effects of the novel quantitative approach to the effects of a tariff equivalent, which is more traditionally used to analyse these types of policies. Local content requirements increase output and value added in the affected sector, but at the expense of other sectors, leading to declines in GDP and trade across the economy. Comparing the two modelling approaches, the differences in outcomes are shown to be significant. 相似文献

This paper examines the impact of attribute presence/absence in choice experiments using covariance heterogeneity models and random coefficient models. Results show that attribute presence/absence impacts both mean utility (systematic components) and choice variability (random components). Biased mean effects can occur by not accounting for choice variability. Further, even if one accounts for choice variability, attribute effects can differ because of attribute presence/absence. Managers who use choice experiments to study product changes or new variants should be cautious about excluding potentially essential attributes. Although including more relevant attributes increases choice variability, it also reduces bias. 相似文献

Research on location-based advertising (LBA) suggests that the merits of LBA lie in the fact that consumers can be targeted with location-congruent ads on their personal mobile devices. However, LBA consists of two underlying constructs: a mobile (vs. point-of-sales) advertising medium and location congruency (vs. location incongruency). This study aims to disentangle these underlying constructs by showing that they differentially affect the efficacy of an ad. Using a virtual reality lab experiment, this study shows that location-congruent ads result in increased choice for the target brand as compared to location-incongruent ads, independent of medium type. However, in location-incongruent situations, mobile ads attracted more attention than point-of-sales display ads. The advantages of LBA thus do not seem to emanate from medium type, but rather from the congruency between the ad and product location. When the ad is received at a different location than the product, the mobile medium is able to enhance consumers' ad attention. 相似文献
