Overcommitment of development capacity or development resource deficiencies are important problems in new product development (NPD). Existing approaches to development resource planning have largely neglected the issue of resource magnitude required for NPD. This research aims to fill the void by developing a simple higher‐level aggregate model based on an intuitive idea: The number of new product families that a firm can effectively undertake is bound by the complexity of its products or systems and the total amount of resources allocated to NPD. This study examines three manufacturing companies to verify the proposed model. The empirical results confirm the study's initial hypothesis: The more complex the product family, the smaller the number of product families that are launched per unit of revenue. Several suggestions and implications for managing NPD resources are discussed, such as how this study's model can establish an upper limit for the capacity to develop and launch new product families. 相似文献

Using Meta-Analysis and GIS for Value Transfer and Scaling Up: Valuing Climate Change Induced Losses of European Wetlands 总被引:2,自引:0,他引:2
Luke M. Brander Ingo Br?uer Holger Gerdes Andrea Ghermandi Onno Kuik Anil Markandya St?le Navrud Paulo A. L. D. Nunes Marije Schaafsma Hans Vos Alfred Wagtendonk 《Environmental and Resource Economics》2012,52(3):395-413
There is growing policy and academic interest in transferring ecosystem service values from existing valuation studies to other ecosystem sites at a large geographic scale. Despite the evident policy demand for this combined transfer and “scaling up” of values, an approach to value transfer that addresses the challenges inherent in assessing ecosystem changes at a national or regional level is not available. This paper proposes a methodology for scaling up ecosystem service values to estimate the welfare effects of ecosystem change at this larger geographical scale. The methodology is illustrated by applying it to value the impact of climate change on European wetlands for the period 2000–2050. The proposed methodology makes use of meta-analysis to produce a value function. The parameters of the value function include spatial variables on wetland size and abundance, GDP per capita, and population. A geographic information system is used to construct a database of wetland sites in the case study region with information on these spatial variables. Site-specific ecosystem service values are subsequently estimated using the meta-analytic value function. The proposed method is shown to enable the adjustment of transferred values to reflect variation in important spatial variables and to account for changes in the stock of ecosystems. 相似文献

Many developing countries have adopted the market approach for expanding the supply of child care, but little is known about the economic behavior of independent providers. Drawing on uniquely rich census data on child care providers from São Paulo, we document three main facts: (1) the stock of private suppliers is considerably larger in high-income city districts; (2) the quality of private provision – as measured by teachers' schooling, group size and equipment – is highly heterogeneous across space and increases systematically with local household income; and (3) a considerable share of centers operates below recommended (but not regulated) quality standards, especially in low-income districts. These findings are consistent with a model of endogenous entry and quality choices by heterogeneous providers. Market-driven heterogeneity in the quality of provision across space is an important consideration for the design of regulations in child care markets. 相似文献

We examine the impact of adopting International Accounting Standard 39 – Financial Instruments: Recognition and Measurement (IAS 39) by non-US commercial banks cross-listed in the US on earnings volatility and its risk relevance. As IAS 39 requires the recognition of unrealized fair-value gains and losses for a larger set of financial and derivative-financial instruments, and the impairment charges for loans and receivables, we expect and find that IAS 39 adoption increased earnings volatility in IFRS-adopting firms from 2005 onwards. Furthermore, both hedge accounting and the fair value option under IAS 39 are designed to reduce mixed-measurement volatility and to improve the sensitivity of firm risk measures to earnings volatility. We also find that the relationship between credit ratings (proxy for risk) and earnings volatility increases for IFRS-adopting firms after 2005. The evidence is consistent with the argument that IAS 39 increases the credit relevance of earnings volatility. 相似文献

We examine the role of geographic, economic, and institutional factors in attracting Foreign Direct Investment (FDI) in Europe, using a cross-section of inward bilateral investments. We estimate and assess the expected benefits, the required reform efforts, and the efficiency of reform options corresponding to a convergence of Portuguese institutions to EU standards. We conclude that improving home institutions is likely to have a quantitatively very significant role in attracting FDI. Geographical and market size factors also play a role. Reforms promoting the independence of financial institutions and a leaner bureaucracy, lowering political risk and corruption, and improving the investment code may significantly affect the amount of bilateral inward FDI that is targeted to Portugal. 相似文献

In the standard models of North-South technological-knowledge diffusion, the larger the initial technological-knowledge gap between countries, the greater the Southern catching up. However, this result does not adjust well to Southern reality as a whole. The purpose of this paper is to demonstrate that the disparity between the theoretical outcome and the empirical findings can be reduced by considering that: (i) the South can only imitate Northern technological knowledge when it is sufficiently close to the Northern frontier; (ii) the advantage of the South's moderate backwardness, together with its imitation capacity, is a mechanism of catching up with the North; and (iii) the Southern catching-up specification can be country specific. In particular, we show that the behavior of the South's relative level of employed human capital affects Southern imitation capacity and depends on the catching-up specifications. 相似文献

We characterize the optimal auction in an independent private values framework for a completely general distribution of valuations. We do this introducing a new concept: the generalized virtual valuation. To show the wider applicability of this concept we present two examples showing how to extend the classical models of Mussa and Rosen and Baron and Myerson for arbitrary distributions. 相似文献
