Capital Expansion, Endogenous Growth and Equilibrium Unemployment

A model is developed, which captures the interactions of unemployment and economic growth in general equilibrium. The economy evolves along a correct-expectations equilibrium path exhibiting endogenous job rationing, and productivity growth is driven by installation of new capital. Under the maintained hypothesis that the elasticity of substitution between capital and labour is less than unity, unemployment benefits are shown to shift up the whole path of equilibrium unemployment, leaving the economy with a higher natural rate of unemployment and lowering the long-run growth rate permanently. Investment tax credits financed by lump sum taxes on total income are capable of lowering the natural rate and raising the economy's growth rate.     

A Conjoint‐Hazard Model of the Timing of Buyers' Upgrading to Improved Versions of High‐Technology Products*

Understanding consumers' upgrading behavior is essential to product planning. Product managers would like to know what fraction of customers would upgrade to new and improved versions, and how fast. This paper presents a method to forecast the sales path of an improved version of a high‐technology product defined in terms of its price path and multiattribute product specification. The approach is potentially useful to managers to answer what‐if questions on the effects of alternative price paths and product specifications of the upgrade on when and what fraction of customers will upgrade. By doing such analysis for several product options under consideration, managers can choose the best feature specification and price path for the upgrade. The proposed approach integrates an individual‐level conjoint utility model with a hazard function specification. The first stage of estimation (i.e., conjoint analysis) measures individual‐level multiattribute utility functions, and the second stage (i.e., duration analysis) calibrates the coefficients of predictor variables of the time to upgrade via maximum likelihood. An illustrative application in the personal digital assistant (PDA) category confirms the predictive validity and potential usefulness of the proposed approach. Among the empirical findings are that higher upgrade costs and expectation of faster product improvement tend to delay buyers' upgrading decisions. The roles of other predictor variables such as product category characteristics, consumer characteristics, and peer pressure were also confirmed.     

Development Resource Planning: Complexity of Product Development and the Capacity to Launch New Products

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.     

Hedonic vs. utilitarian consumption: A cross-cultural perspective based on cultural conditioning

This study investigates the effects of cultural conditioning, product type, and benefit claim type on attitudes and brand personality perceptions among consumers from a society that is more culturally conditioned towards utilitarian consumption (Shanghai, China) and an economy that is less culturally conditioned towards utilitarian consumption (Singapore). Our findings reveal that consumers in Shanghai preferred ads promoting utilitarian rather than hedonic products. They also rated brands of utilitarian products as more sophisticated, competent, exciting, and sincere than hedonic products. No such difference was observed among Singaporeans. These consumers preferred hedonic over utilitarian products but did not perceive them as being different from utilitarian products in terms of brand personality. Theoretical and managerial implications are forwarded, together with directions for future research.     

Dynamic connectedness network in economic policy uncertainties

This study investigates the dynamic connectedness across nine economic policy uncertainty indexes. Our results indicate that the total spillover index is on average 67.4%, indicating a high level of interconnectedness across the nine indexes. In particular, the EU is the largest transmitter of uncertainty connectedness. In addition, China becomes a net transmitter of connectedness during the global financial crisis and European debt crisis. This finding indicates that the uncertainty of Chinese economic policy is an important contributor to the connectedness of the uncertainty network.     

The effects of learning organization culture on the practices of human knowledge‐creation: an empirical research study in Korea

This research aims to identify the influence of learning organization culture on the practices of organizational knowledge‐creation. Actionable knowledge‐creation practices are put forward as a variable in preference to the learning process itself because they may be more closely related to the achievement of individual and/or organizational performance improvement. Learning organization culture is defined in terms of the seven dimensions of the learning organization established by Watkins and Marsick and their questionnaire based on these dimensions is adapted for the present study. In order to measure knowledge‐creation practices, the knowledge conversion theory of Nonaka and Takeuchi was applied. Confirmatory factor analysis and measurement of internal consistency analyses were used to examine the psychometric properties of the instruments. Multivariate analyses were utilized for measuring the influential relations between variables. The results indicate that the proposed structural model is a valid concept in the Korean context for the purposes of the present research. Learning organization culture shows a strong and positive impact on organizational knowledge‐creation practices. Conclusions and implications are discussed.     

The productivity debate of East Asia revisited: a stochastic frontier approach

This paper applies a stochastic frontier production model to the data from Penn World Table's 49 countries over the period 1965 to 1990, to decompose total factor productivity growth into technical change and technical efficiency change. Empirical results show East Asian countries led the world in productivity growth, mainly because their technical efficiency gain was so much faster than that of other countries. East Asian countries also registered rapid technical change, which was comparable to that of the G6 countries after the late 1980s. The results provide evidence that negate the hypothesis that East Asian growth was mostly input-driven and unsustainable.     

Do high performance work practices work in South Korea?

The distribution of so‐called high performance work practices (HPWPs) in South Korean manufacturing is mapped showing their relative scarcity. Contextual and institutional factors associated with the 1997–98 financial crisis are advanced to explain these findings. Nevertheless, anticipating that HPWPs are likely to improve performance, we tested several hypotheses. Employment security, teams, training, job enrichment and information sharing have a positive effect on performance; however there is no evidence of synergy. Most HPWP practices are partially mediated by worker attachment to their workplace. Government workplace reform policy, firms' business and labour utilisation strategy, and the presence of professional management contribute to performance.     

A RE-EXAMINATION OF PRODUCTION FUNCTIONS AND EFFICIENCY ESTIMATES FOR THE NATIONAL BASKETBALL ASSOCIATION

This paper seeks to re‐examine the issue of estimating team efficiency for sports teams via an application of data from the National Basketball Association. This paper argues that the inputs the coaches allocate are the players the team employs. Therefore, this paper employs a measure of playing talent in modeling team production. Unlike previous studies, which only employed one measure of playing talent, we employ measures of guards, small forwards and big men in a study of basketball. This paper also argues that the time‐varying stochastic frontier models with the identical temporal pattern assumption such as Lee and Schmidt and Battese and Coelli cannot be used in the analysis of team efficiency in sports. The evidence we present shows by hypothesis test that this argument holds.     

Effects of team inputs and intrateam processes on perceptions of team viability and member satisfaction in nascent ventures

A new venture team is a particular type of top management team neglected by the literature. This study investigated the effects of team inputs and processes on team members' perceptions of team viability and satisfaction in nascent ventures. These outcomes are important as they may be antecedents of team perseverance. The study of 51 new venture teams showed that the presence of a distinct leader was positively related to team satisfaction, while member diversity in educational backgrounds was positively related to perceived team viability. Intrateam processes of social integration and open communication were positively related to both perceived team viability and member satisfaction. Copyright © 2006 John Wiley & Sons, Ltd.
