Few studies have explored the relationship between green products development (GPD) and product portfolio management (PPM). When considering evidence from emerging economies, the knowledge gap is even deeper. Consequently, the objective of this work is to analyze how green and traditional practices of new product development (NPD) influence product portfolio and NPD performance. In addition, we explore how GPD opens new markets and technology opportunities. The empirical evidence is based on a sample of firms that are developing products and belong to innovative industrial sectors in Brazil. In general, the framework developed and tested in this research indicates the following: (i) the adoption of GPD practices significantly influences product portfolio performance; (ii) the adoption of GPD practices tends to generate positive results with regard to obtaining technological and market opportunities; (iii) the adoption of traditional PPM practices influences the dependent factors. Unexpectedly, correlations between a firm's size or age and its performance were not confirmed. This is the first empirical evidence relating GPD, PPM, and market and technology opportunities in Brazil. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment  相似文献

This study develops and tests a model of information search in complex buying. We incorporate three categories of influences of organizational, personal and situational factors that affect information searching efforts. A sample of 96 of the largest Brazilian firms reported their use of the various influences in the decision to purchase integrated business management systems. Findings show that formalization of the organization is a key driver of information search efforts. Situational characteristics of importance, novelty and bargaining power increased the level of information search. Also, conformity of the purchasing agent and organizational centralization reduce information search efforts among the sampled Brazilian firms.  相似文献

The purpose of this paper is to evaluate the impact of lean product development (LPD) in the Brazilian automotive sector. A mailed-questionnaire survey was used to examine 23 questions about LPD principles and practices. The target population for the study was Brazil's largest product development and design companies. The study identified that although the automobile sector is seen as a reference in the adoption of lean practices, there is still potential for improvement by establishing partnership relations with suppliers, and with those on the other points of the chain by identifying what provides value to clients. Set-based concurrent engineering is also a practice that needs to be better developed, as well as the value stream mapping tool to identify waste and activities that add value to the product development process. There has been no previous study of this nature in Brazil that characterizes the sector and highlights its importance in relation to the global scene, providing incentives to international investors. The value of the work is in the results that allow diagnosing the lean development practices that are most used in the automotive sector. Moreover, the survey questions can be applied in other economic sectors and at companies of other sizes. The study contributed to providing a systematic view of the product development process from the perspective of people, processes, and technology, and assists companies and academics manage change.  相似文献

We consider a model of repeated (relationship) lending in which some contingencies that are relevant for a bank’s decision to finance a project cannot be described contractually. The hazards related to this lack of contractibility can be magnified by actions taken by an entrepreneur. The continuation value of a lending relationship induces borrowers to take actions that minimize the ex-post conflict of interests resulting from contractual incompleteness. The optimal lending relationship is stationary on the equilibrium path. A robust feature of an optimal lending relationship is that the action schedule (as a function of project types) adopted by the entrepreneur is either a constant or a step function. Hence, the bank imposes to the entrepreneur a finite set of decisions from which he can pick his action, bounding his discretion over decisions. This leads to lower interest rates charged by the bank and to efficient refinancing in a lending relationship when compared to arm’s length financing.  相似文献

Considering an integrated area, this paper deals with the balance between the positive effects in the degree of economic cohesion resulting from R&D subsidies, temporarily granted from an imitator and less developed country, and the external negative effects arising from the eventual creation of excessive public deficits.We propose and numerically solve a model of a monetary union between two countries, one being innovator and the other imitator. Results suggest the pertinence of allowing for a temporary differentiation of fiscal discipline rules in favour of the less developed country. R&D subsidies granted by this country seem to lead to an easier catching-up without producing important negative external effects, also as not hurting severely the conditions for long-run sustainability of public accounts.  相似文献

We develop a tractable structural model to estimate a firm's default probability by modeling its asset and debt behavior. The model incorporates jump factors. For a set of Brazilian large corporations, we compare the structural model results to the default probabilities predicted by a survival analysis applied to the Central Bank debt information database. Our model outperforms other structural models. In a last step, we use a firm's sector failure probabilities to calibrate the model. This process is executed by adjusting the model jump volatility and it helps to explain the differences between debt and equity market failure probabilities.  相似文献

Many authors point out that the front-end of new product development (NPD) is a critical success factor in the NPD process and that numerous companies face difficulties in carrying it out appropriately. Therefore, it is important to develop new theories and proposals that support the effective implementation of this earliest phase of NPD. This paper presents a new method to support the development of front-end activities based on integrating technology roadmapping (TRM) and project portfolio management (PPM). This new method, called the ITP Method, was implemented at a small Brazilian high-tech company in the nanotechnology industry to explore the integration proposal. The case study demonstrated that the ITP Method provides a systematic procedure for the fuzzy front-end and integrates innovation perspectives into a single roadmap, which allows for a better alignment of business efforts and communication of product innovation goals. Furthermore, the results indicated that the method may also improve quality, functional integration and strategy alignment.  相似文献
