Abstract. The fact that an occurrence of a unit root in real output is inconsistent with the notion that business cycles are stationary fluctuations around a deterministic trend makes this an important topic for empirical investigation. We examine this issue for 24 Chinese provinces using the recently developed Lagrange multiplier panel unit root test which allows for a structural break. Our main finding is that real gross domestic product (GDP) and real GDP per capita for Chinese provinces are stationary fluctuations around a deterministic trend. 相似文献

Analyzing the way organizations function and the processes that operate within these organizations is an important managerial responsibility. We have adopted a people–oriented approach called organizational energy to develop a simple process for diagnosing the level of satisfaction of scientists working in R&D laboratories. Psychic energy as reflected in different work activities in an organization is manifested in energy generating and energy draining activities that can be reduced to an energy count. The present study assesses the use of mental energy by scientific personnel working in three national laboratories in India with the objective of increasing the energy count for improving organizational effectiveness. We hope that the results can be used as the basis for initiating action to improve the motivation and utilization of scientists in India, to support the overall goal of self–reliance in science and technology. 相似文献

This study tests and contrasts the ability of multidimensional scaling (MDS) and nonlinear mapping (NLM) in recovering complex
data structures in attribute space, and aiding researchers and practitioners in making neighborhood interpretations. The relative
merits of both MDS and NLM for product positioning are explored and discussed. A formal comparison of the performance of NLM
versus MDS is presented using both simulated and actual data. The results of this study provide direction as to the conditions
under which a nonlinear mapping algorithm is preferable over MDS. 相似文献

Most organizations use new product development (NPD) processes that consist of activities and review points. Activities basically solve problems and gather and produce information about the viability of successfully completing the project. Interspersed between the development activities are review points where project information is reviewed and a decision is made to either go on to the next stage of the process, stop it prior to completion, or hold it until more information is gathered and a better decision can be made. The review points are for controlling risk, prioritizing projects, and allocating resources, and the review team typically is cross‐disciplinary, comprising senior managers from marketing, finance, research and development (R&D), or manufacturing. Over the past four decades, research has greatly advanced knowledge with respect to NPD activities; however, much less is known about review practices. For this reason, the present paper reports findings of a study on NPD project review practices from 425 Product Development & Management Association (PDMA) members. The focus is on three decision points in the NPD process common across organizations (i.e., initial screen, prior to development and testing, and prior to commercialization). In this paper, the number of (1) review points used, (2) review criteria, (3) decision makers on review committees and the proficiency with which various evaluation criteria are used are compared across incremental and radical projects and across functional areas (i.e., marketing, technical, financial). Furthermore, the associations between these NPD review practices and new product performance are examined. Selected results show that more review points are used for radical NPD projects than incremental ones, and this is related to a relatively lower rate of survival for radical projects. The findings also show that the number of criteria used to evaluate NPD projects increases as NPD projects progress and that the number of review team members grows over the stages, too. Surprisingly, the results reveal that more criteria are used to evaluate incremental NPD projects than radical ones. As expected, managers appear to more proficiently use evaluation criteria when making project continuation/termination decisions for incremental projects; they use these criteria less proficiently during the development of radical projects, precisely when proficiency is most critical. At each review point, technical criteria were found to be the most frequently used type for incremental projects, and financial criteria were the most commonly used type for radical ones. Importantly, only review proficiency is significantly associated with performance; the number of review points, review team size, and number of review criteria are not associated with new product performance. Furthermore, only the coefficient for proficiently using marketing criteria was significantly related to new product program performance; the proficiency of using financial and technical information has no association with performance. Finally, across the three focal review points of the NPD process in this study, only the coefficient for proficiency at the first review point, (i.e., the initial screen) is significantly greater than zero. The results are discussed with respect to research and managerial practice, and future research directions are offered. 相似文献

abstract We propose a framework to understand interpartner legitimacy in strategic alliances. Interpartner legitimacy is the mutual acknowledgment by the alliance partners that their actions are proper in the developmental processes of the alliance. We argue that interpartner legitimacy is needed for cooperation to achieve alliance objectives. We propose three types of interpartner legitimacy – pragmatic, moral, and cognitive legitimacy – and discuss the dynamics of these three types in the formation, operation, and outcome stages of alliance development. Further, we discuss the salience of interpartner legitimacy in different alliance types. Finally, we derive propositions for further research, and discuss strategies that alliance managers can adopt to develop interpartner legitimacy. 相似文献

This paper investigates the dynamics of international government bond market integration in six of the G7 economies over two decades leading up to the global crisis. It examines whether such integration had been significant; the extent to which integration at the short and long end of the yield curve differed; the nature of such integration; and the extent of the decoupling of the long rates from short rates. These issues are investigated using the rigorous smooth-transition copula-GARCH model framework. The results show that integration at the long end of the yield curve had been increasing, had become pronounced, and was significantly greater than at the short end. Decoupling between the short and long end of the yield curve was notable, with important implications for the efficacy of monetary policy in the period before the crisis. 相似文献

Using bank-level data from India, we examine the impact of ownership on the reaction of banks to monetary policy, and also test whether the reaction of different types of banks to monetary policy changes is different in easy and tight policy regimes. Our results suggest that there are considerable differences in the reactions of different types of banks to monetary policy initiatives of the central bank, and that the bank lending channel of monetary policy is likely to be much more effective in a tight money period than in an easy money period. We also find differences in impact of monetary policy changes on less risky short-term and more risky medium-term lending. We discuss the policy implications of the findings. 相似文献

We show that small firms using syndicated loans for their mid- and long-term financial needs have significantly higher leverage than firms that do not borrow in this market. This difference cannot be attributed to firm characteristics like the availability of growth opportunities, asset tangibility, R&D spending, profitability and net sales that are known to influence capital structure. We also find that the capital structure of other firms that borrow in the syndicated loan market is not different from those that do not. We show that already highly leveraged small firms are more likely to borrow in the syndicated loan market than other firms. The higher debt in the capital structure of small firms that rely on syndicated loans consequently can be attributed to the availability of capital rather than demand for capital, as shown more generally by Faulkender and Petersen (Rev Financ Stud 19(1):45?C79, 2006). 相似文献

Since the mid-1980s, stock market activity has increased substantiallyin many developing countries. This article first examines themain characteristics of emerging stock markets and illustratesthe evolution of equity prices in these markets during the lastdecade. It then discusses the reasons for the markets' growthand assesses the extent to which they have been affected bydomestic policies and external factors. The authors discussthe likely benefits of these markets, the effects any abruptcorrection in stock prices could have for the economy, and theways in which these markets can be made more efficient. 相似文献

Three processes reflecting persistence of volatility are initially formulated by evaluating three Lévy processes at a time change given by the integral of a mean-reverting square root process. The model for the mean-reverting time change is then generalized to include non-Gaussian models that are solutions to Ornstein-Uhlenbeck equations driven by one-sided discontinuous Lévy processes permitting correlation with the stock. Positive stock price processes are obtained by exponentiating and mean correcting these processes, or alternatively by stochastically exponentiating these processes. The characteristic functions for the log price can be used to yield option prices via the fast Fourier transform. In general mean-corrected exponentiation performs better than employing the stochastic exponential. It is observed that the mean-corrected exponential model is not a martingale in the filtration in which it is originally defined. This leads us to formulate and investigate the important property of martingale marginals where we seek martingales in altered filtrations consistent with the one-dimensional marginal distributions of the level of the process at each future date. 相似文献
