Introducing Interface Management in New Product Family Development   总被引:6,自引:0,他引:6  
Creating product platforms from which many products can easily be leveraged is an issue of increasing concern for many companies. This article introduces and explores the concept of interface management (IM) in new product platform development. IM is the distinct process of developing and defining the physical platform interfaces. The concept of IM is empirically explored in two product family development projects in the Swedish manufacturing industry that have been longitudinally studied for more than 3 years. It is proposed that firms which have a product family development approach that is associated with an extensive IM process enjoy a high degree of freedom in deciding how to balance its time to market for individual products with the beneficial utilization of design familiarities across all products. Moreover, if product managers understand and explicitly focus on the IM process, the often challenging shift from a single product development approach to a product family development approach is likely to be facilitated. © 1999 Elsevier Science Inc.  相似文献

I investigate empirically the role of religion and political institutions in policies against human trafficking, using the new 3P Anti-trafficking Policy Index. The dataset contains 175 countries. The results show that governments in countries with Christian majorities implement stricter anti-trafficking policies than governments in countries with Muslim majorities. The differences between countries with Christian and Muslim majorities are pronounced in dictatorships but less so in democracies. For example, the 3P Anti-Trafficking Policy Index in a dictatorship with no Muslims was by 1.9 points higher than in an otherwise identical but purely Muslim dictatorship (on a scale from 3 to 15). The association between religion and the overall 3P Anti-trafficking Policy Index is driven by protection and prevention policies. As compared to prosecution policies that mainly target the perpetrators of human trafficking, protection and prevention policies mainly protect the victims of human trafficking, i.e. predominantly women. The conclusions are consistent with other empirical findings regarding the association between religion, political institutions, and human development.  相似文献

Many types of data are often incompletely observed. How incompletely is typically randomly determined. H eitjan and R ubin ( Annals of Statistics , 1991) proposed a condition, "coarsened at random" or CAR, ensuring ignorability of this randomness in discrete sample spaces. In general sample spaces CAR comes in two flavors according to whether it is defined in terms of probabilities or densities. In this paper, CAR defined in terms of densities, called relative CAR, is discussed as a condition for ignorability in a statistical model allowing for partial observation of random elements determining the degree of incompleteness in the observation of the data.  相似文献

This paper develops an international trade model where firms in a duopoly may diversify their technologies for strategic reasons. The firms face the same set of technologies given by a tradeoff between marginal costs and fixed costs, but depending on trade costs firms may choose different technologies. Market integration may induce a technological restructuring where firms either diversify their technologies or switch to a homogeneous technology. In general, market integration improves welfare. However, a small decrease of trade costs which induces a switch from heterogeneous technologies to a homogeneous technology may locally reduce global welfare. The model also shows that productivity differences lead to intra‐industry firm heterogeneity in size and exports similar to the “new–new” trade models with monopolistic competition.  相似文献

Exploration and exploitation constitute two separate, potentially conflicting strategic choices for firms engaged in international strategic alliances. Our empirical study challenges the ambidexterity argument and demonstrates that exploration and exploitation are separate (though not necessarily antithetical) strategies with different antecedents and performance consequences.Our results show that while competency similarity is conducive to upstream innovative performance, prior experience with the partner is potentially damaging for this type of performance and trust and cultural distance do not play significant roles. When the motive is efficiency and downstream market performance, prior experience with the partner instead is beneficial, as are high levels of trust and low levels of cultural distance. These findings have key implications for literature on strategic fit and alliance performance.  相似文献

A widespread concern is that labor market institutions erode in the course of globalization, which, in turn, decreases employment and wages. By using panel data and cross-sectional data, I investigate the influence of globalization on labor market regulation. I use the indicators of labor market institutions by Gwartney et al. (2012) and the KOF indices of globalization. To deal with potential reverse causality, I employ a system GMM panel estimator and use a constructed trade share as proposed by Frankel and Romer (1999) as an instrumental variable for globalization in cross-sectional models. The results do not show that globalization induced labor market deregulation.  相似文献

We discuss the design of interactive, internet based benchmarking using parametric (statistical) as well as non-parametric (DEA) models. The user receives benchmarks and improvement potentials. The user is also given the possibility to search different efficiency frontiers and hereby to explore alternative improvement strategies. Implementations of both a parametric and a non-parametric model are presented.  相似文献

This paper examines the GATT/WTO rules for anti-dumping measures in a duopoly model with both horizontal and vertical product differentiation. The GATT/WTO rules allow for anti-dumping measures if domestic producers, exposed to price discrimination, also demonstrate injury where price-undercutting is an important indicator of the latter. The paper shows that the procedure for calculating injury is flawed due to negligence of quality differences in the calculation of the margin of price-undercutting. This gives countries with high-quality producers an option to practice protectionism. This asymmetry between countries in ability to implement anti-dumping measures predominantly favors the developed countries which are specialized in producing high-quality products. The paper suggests an overall critical look at the lenient rules for implementing anti-dumping measures—especially the rules for injury determination—in order to restrict the use of such measures to a minimum and to move the world economy closer to free trade.  相似文献

Entrepreneurial finance literature has highlighted that institutionalinvestors are the main contributors to private equity funds.This paper complements these findings by documenting that institutionalinvestors also invest directly in private equity. A major concernfor such investments is the higher agency costs associated withprivate equity. We show that institutions invest in privatefirms with governance mechanisms that tend to reduce the expectedagency costs and risk of minority expropriation. Good governancemechanisms further allow institutional investors to enjoy thebenefits of syndication and thereby reduce idiosyncratic risk.In addition, we show that institutional investments tend tobe followed by further improvements in corporate governanceand tend to occur in high-growth firms within research and developmentintensive industries.  相似文献
