Innovative features such as hands‐free car entry and ignition systems, stop‐start devices, telematics systems, and panoramic windshields are increasingly important to carmakers' innovation strategies. However, while product‐centric innovation has been extensively studied, there is less insight into the way companies implement their feature‐innovation strategies. The capability to explore, integrate, and deploy such attractive features is a critical dynamic capability; it allows carmakers to refresh their products, develop their competences, and maintain the efficiency of their traditional new product development. This research investigates the structures and processes of feature innovation in the automotive industry. It is based on a global investigation encompassing 9 generalist carmakers and 26 cases of feature innovation. The results show a clear trend, over the past decade, toward a structure of autonomous “advanced engineering” units and processes that are responsible for exploring innovative features and transferring them to multiple products. This paper details the key attributes of these units, and the role they play along the multiproduct learning cycle. Supplementing this structural analysis, the paper also identifies the coordination patterns between exploration and new product development activities. These results provide industry‐level insights into the way firms organize their feature‐innovation capability, and bring empirical elements to the ambidexterity literature.  相似文献

Under Philip II, Castile was the first country with a large nation‐wide domestic public debt. A new view of that fiscal system is presented that is potentially relevant for other fiscal systems in Europe before 1800. The credibility of the debt, mostly in perpetual redeemable annuities, was enhanced by decentralized funding through taxes administered by cities making up the Realm in the Cortes. The accumulation of short‐term debt depended on refinancing through long‐term debt. Financial crises in the short‐term debt occurred when the service of the long‐term debt reached the revenues of its servicing taxes. They were not caused by liquidity crises and were resolved after protracted negotiations in the Cortes by tax increases and interest rate reductions.  相似文献

Using first-hand data from the 2009 Employment and Informal Sector Survey (EESIC) in the two largest cities of the Republic of Congo, Brazzaville and Pointe-Noire, we analyze the impact of education on labour market outcomes, and identify the segments where education pays off the most. Multivariate analyses of the risk of unemployment and sectoral choice indicate that young people face serious difficulties in the labour market: for most of them, their only choice is to remain unemployed or to join the informal sector. To measure the specific impact of schooling on earnings, we address issues related to sample selection and endogeneity of education in the earnings function. The results shed light on heterogeneity in the returns to schooling across the two main cities and institutional sectors. An important finding is that the informal sector does not systematically lag behind the formal sectors in terms of returns to education. We emphasize convex returns to education, meaning that the last years in secondary and tertiary schooling yield the highest returns, while those of primary education are generally lower. This convexity is also apparent in the informal sector, where education (albeit on another scale) again appears as an important determinant of earnings.  相似文献

Firms use sales contests to motivate salespeople; however, knowledge of their impact on salespeople is scarce. Acceptance of the contest, according to goal-setting theory, is essential for a contest to motivate salespeople (Hile-Hart et al., 1989). Yet attitude toward (or preference for) the contest is an important factor in motivating effort (Murphy and Dacin, 1998). In an experiment with financial services salespeople, this study examines the compliance effect (Chowdhury, 1993) and propositions that Murphy and Dacin (1998) suggest. Results support goal-setting theory, but also the importance of salesperson's attitude to the contest. While the study partially confirms Chowdhury's (1993) results regarding the influence of contest difficulty, his suggestion that difficulty leads to goal acceptance was not. Valence for winning does not relate to attitude significantly in the study here, contrary to Murphy and Dacin's (1998) propositions. The article develops an integrative model with implications for research and practice.  相似文献

In this paper, we empirically investigate whether collateral mitigates adverse selection problems in a loan market. Theory predicts a negative relation between the presence of collateral and the interest spread of a loan. However, bankers??view and most empirical evidence contradict this prediction and support the observed-risk hypothesis instead. We provide new evidence from a sample of 4,940 bank loans from 31 countries. We test whether the degree of information asymmetry affects the positive link between collateral and the loan spread and find that a greater degree of information asymmetry reduces this positive relation. This finding provides support for both the adverse selection and observed-risk hypotheses.  相似文献

The main purpose of this paper is to examine empirically the time series properties of the French Market Volatility Index (VX1). We also examine the VX1's ability to forecast future realized market volatility and finds a strong relationship. More importantly, we show how the index can be used to generate volatility forecasts over different horizons and that these forecasts are reasonably accurate predictors of future realized volatility.  相似文献

In this article I examine corporative management practices inelectronics firms in Boston and in Silicon Valley from the 1920sto the 1960s. Managers in several key firms developed thesepractices in response to political and professional ideologiesand as a way to address the problems of hiring, using, and retaininga highly skilled work force. They did this independently ofthe welfare capitalism plans of corporations such as EastmanKodak and before the guru theorists and work empowerment programsof the 1960s. The corporatist methods first developed in Bostonand further refined in Silicon Valley later diffused to mostU.S. firms in the software, computer, Internet, and biotechnologyindustries.  相似文献

This research starts from the observation that common desmoothing models are likely to generate some extreme returns that will distort risk measurement and hence can lead to investment decisions that are suboptimal relative to those that would be made if a transaction‐based index were available. Thus, we propose to improve the desmoothing models by incorporating a robust filter into the procedure. We report that in addition to properly treating for smoothing, the method prevents the occurrence of extreme values. As shown with U.S. data, our method leads to desmoothed series whose characteristics are akin to those of transaction‐based indices.  相似文献

Existence of Nash networks in one-way flow models   总被引:1,自引:0,他引:1  
This paper addresses the existence of Nash equilibria in one-way flow models in a number of different settings. In these models players form costly links with other players and obtain resources from them through the directed path connecting them. We find that heterogeneity in the costs of establishing links plays a crucial role for the existence of Nash networks. The paper also provides conditions for the existence of Nash networks in models where costs and values of links are heterogeneous. We would like to thank an anonymous referee for useful suggestions. We would also like to thank Hans Haller and participants at the AEA Meetings 2007 for helpful comments.
