Exploring the interaction between incubators and industrial clusters: the case of the itri incubator in Taiwan

This article aims to explore the interaction between incubators and industrial clusters, which is an important linkage for local development but has not been analyzed in the literature. A model is proposed to describe this interaction. The Industrial Technology Research Institute (ITRI) Incubator within the Hsinchu industrial cluster, the core of Taiwan's technology industries, is considered to be an empirical case. This case is investigated with the proposed model and methods including data analysis, in–depth interviews, manager surveys and stakeholder analysis. It was found that the clustering effect in the Hsinchu industrial cluster is main factor in the ITRI Incubator's development. The ITRI Incubator in turn reinforces the cluster in some aspects as feedback. This result confirms the existence and importance of this interaction in local development. It is recommended that government officials and incubator managers take account of this interaction in operating an incubator program and utilize the proposed model to analyze the incubator's contributions to its industrial cluster.     

The effects of network groups on minority employee turnover intentions

Companies in the United States are concerned with retaining minority employees to maintain or increase the diversity of their workforce. Here we assess the value of one approach companies have used to retain minority employees: “network” groups. Based on data obtained from a large company with extensive network groups, this study compares the turnover intentions of minority employees who have joined one of the company's network groups to those who have not joined one of the company's network groups. The data show that employee network groups can be useful in helping companies retain managerial‐level minority employees. Extensive recommendations are provided to help organizations maximize the effectiveness of network groups. © 2002 Wiley Periodicals, Inc.     

Technical innovation and 3.5 mobile phone generation: Lessons from Korea

In 1996, the Korean mobile communication market was the first in the world to commercialize the code division multiple access (CDMA). Since then, the voice-based mobile phone market has continued to grow and has now reached near saturation. Having recognized the potential of the mobile data service as a new source of profit, telecommunication operators are scrambling to evolve 3.5 generation (3.5G) technology in order to lead market competition. Recently, the Korean 3.5G mobile telecom market has faced stiff competition from CDMA-based EVDO Rev.A and global system for mobile telecommunications (GSM)-based high-speed downlink packet access (HSDPA). In addition, the world's first wireless LAN-based wireless broadband internet (WiBro) service was commercialized in June, 2006. This paper reviews the current status of the 3.5G technology and analyzes the service standardization strategies from the viewpoint of technological evolutions. This paper also suggests implications for Korea's specific circumstances where different mobile telecom technologies complement and compete with one another. Korea's experiences may serve as important lessons for other countries or operators who try to introduce the 3G and look beyond mobile telecom technologies.     

Stock market volatility,the news,and monetary policy

The dynamic relationship linking the volatility of equity prices with “the news” and the expected path for monetary policy is investigated. Previous results that link the impact of the news about real activity to changes in current and future interest rates are employed in developing a positive link between changes in volatility and the news. Empirically, our results uncover a positive and statistically significant response of the CBOE volatility index, VIX, to unanticipated changes in employment, but not to inflation. Hence, agents' expectations for the policy response to news have an important influence on the expected volatility of stock prices. (JEL E44, E52)     

A generalized theorem of the maximum

Summary This paper generalizes the Theorem of the Maximum (Berge [2]) to allow for discontinuous changes in the domain and the objective function. It also provides a geometrical version of the (generalized) theorem.This research was supported in part by National Science Foundation Grant SES-86-19012.

Estimation of household preferences for long distance telecommunications carrier

The competitive environment in long-distance telecommunications markets changed considerably with the divestiture of AT&T in 1982. A variety of providers appeared, offering myriad services. In this environment, customer selection of preferred long-distance carrier became more complicated and more important.In this paper, we analyze and quantify the determinants of this choice. To our knowledge, this focus is distinct. By contrast, the literature to date has analyzed the behavioral determinants of calling volume (local and long-distance) and the selection of local service options.In our analysis, we allow the alternative carriers to differ in terms of tariffs, reputation, quality, access, and specialized customer services. We quantify the interactive effects of these carrier attributes and customer demographics upon the selection of carrier. Price and income elasticities are estimated. A distinguishing feature of our analysis is that it examines behavioral differences among households in equal-access and unequal-access areas. We find that households assured of the convenience of 1 + dialling for their chosen carrier in equal-access areas display more rational and sophisticated decision making. On the other hand, households in unequal-access areas display greater status quo effects in their decision making.     

On exact D-optimal designs with 2 two-level factors and n autocorrelated observations

In this paper we consider the exact D-optimal designs for estimation of the unknown parameters in the two factors, each at only two-level, main effects model with autocorrelated errors. The vector of the n random errors in the observed responses is assumed to follow a first-order autoregressive model (AR(1)). The exact D-optimal designs seek the optimal combinations of the design levels as well as the optimal run orders, so that the determinant of the information matrix of BLUEs for the unknown parameters is maximized. Bora-Senta and Moyssiadis (1999) gave some conjectures about the exact D-optimal designs based on their experience of several exhaustive searches. In this paper their conjectures are partially proved to be true.Received: January 2003 / Accepted: October 2003Partially supported by the National Science Council of Taiwan, R.O.C. under grant NSC 91-2115-M-008-013.Supported in part by the National Science Council of Taiwan, R.O.C. under grant NSC 89-2118-M-110-003.     

Selection dynamics and adaptive behavior without much information

This paper uses the experimental method to investigate behavior in a coordination game when the information available to subjects is limited to their feasible choices and their experienced payoffs. In the experiment subjects converge to an absorbing state at rates that are orders of magnitude faster than reinforcement learning algorithms, but slower than under complete information. This state is very close to a mutual best response outcome. All cohorts converged to the market statistic predicted by the interior equilibrium regardless of the information conditions or the stability conditions.
