Optimal diversification,bank value maximization and default probability

This study argues that the optimal level of diversification for the maximization of bank value is asymmetrical and depends on the business cycle. During times of expansion, systematic risks are relatively low; hence, the effect of raising systematic risks from portfolio diversification is slight. Consequently, the benefit of reducing individual risks dominates any loss from raising systematic risks, leading to a higher value for a bank by holding a diversified portfolio of assets. On the contrary, during times of recession, systematic risks are relatively high. It is more likely that the loss from raising systematic risks surpasses the benefit of reducing individual risks from portfolio diversification. Consequently, more diversification leads to lower bank values. Finally, some empirical evidence from the banks in Taiwan is provided.     

Classification and competition analysis of air cargo logistics providers: The case of Taiwan’s high-technology industry

This paper classifies air cargo logistics providers allowing analysis of high-technology manufacturers’ choices of providers. Data are collected from high-technology manufacturers in Taiwan’s science parks. Forwarder providers are put into three categories and nested logit model are applied to explore what service performance factors influence high-technology manufacturers when selecting third party logistics providers. Delivery is found to be the most important factor. It is found, for example, that two express providers with high levels of customer satisfaction and market share could compete more effectively by exercising differential strategies.     

The dark side of logistics outsourcing - Unraveling the potential risks leading to failed relationships

We identify and empirically examine the potential risk factors and their structural relationships that can cause a logistics outsourcing relationship to fail. Specifically, we investigate how the relationship risk as perceived by apparel wholesalers as user firms influence their evaluation on the asset and competence entrusted with their logistics service providers, which are logistics outsourcing risk factors considered important by the former in determining continued relationships with the latter. The results highlight the need for relationship management by user firms to mitigate the risks in asset and competence specifically invested in logistics service providers for their outsourced activities.     

R&D Productivity and the Spillover Effects of High‐tech Industry on the Traditional Manufacturing Sector: The Case of Taiwan

This study sets out to estimate the impact of R&D on productivity within the private sector, with further analysis of the different impacts of R&D within high‐tech and traditional manufacturing firms. We also attempt to examine the spillover effects from R&D investment in the high‐tech sector on productivity growth within the traditional industries. Using a sample of 136 large manufacturing firms during the period 1994–2000, we develop an extended version of the Cobb‐Douglas production function model, and our findings suggest that Taiwan's R&D investment had a significant impact on firm productivity growth, with output elasticity standing at around 0.18. When the sample is divided into high‐tech and traditional firms, the R&D output elasticity in high‐tech firms is significantly greater than that found in traditional firms. In addition, the average rate of return in high‐tech firms is much greater than that estimated for other industries. Besides, our empirical results show that, although significant, the impact of R&D investment from the high‐tech sector, on the productivity growth of traditional firms, is rather limited.     

Using scientific detective videos to support the design of technology learning activities

This article examines the effect of scientific detective video as a vehicle to support the design of technology activities by technology teachers. Ten graduate students, including current and future technology teachers, participated in a required technology graduate course that used scientific detective videos as a pedagogical tool to motivate their interest in science and technology and to reinforce creative competence in designing technology learning activities (TLAs). The participants watched three scientific detective videos and analyzed them for scientific principles and technologies. An analysis report and interview were conducted to collect participants’ understanding and application of scientific principles and technologies. The main findings were that (a) influencing teacher’s design of TLAs through scientific detective videos is feasible; (b) prior personal conditions and external factors influence teacher’s design of TLAs; and (c) the analysis of scientific detective videos helps teachers to design TLAs appropriately. This study demonstrated the broad utility of scientific detective videos for inspiring technology teachers to integrate science and technology in their activity design.     

Simplified Alonso–Mills–Muth model with a monopoly vendor

One important but unrealistic assumption in the simplified Alonso–Mills–Muth (AMM(0)) model is that the composite good is ubiquitous and thus there is zero shopping cost for residents. This paper assumes that the composite good is only sold by a monopoly vendor inside the city and hence a shopping cost is inevitable for residents. It is shown that the vendor will locate at the city boundary in equilibrium. In contrast to the symmetric land rent pattern in the AMM(0) model, the current AMM(k) model offers an asymmetric land rent pattern in equilibrium. Moreover, this paper shows that a rent-maximizing government either regulates the vendor to locate at the central business district (CBD) (when income is high) or does not enact any regulation (when income is low).     

Housing Supply,Demand and Price: Construction Cost,Rental Price and House Price Indices

Housing prices are subject to the impacts of supply as well as demand. While supply is affected by construction costs, demand is determined by the renting/buying considerations of the public. As a result, the construction cost index (CCI) on the supply side and the rental price index (RPI) on the demand side should be closely related to the house price index (HPI). The present study adopts three price indices of the Taiwan housing market, the CCI, the RPI and the HPI, and examines long‐term and short‐term correlations among the three indices. Empirical results indicate that the relationships among three indices are nonlinear. More interestingly, this article finds that the HPI stimulates changes in the CCI and the RPI, although construction costs and rent are viewed as fundamentals in the existing literature. This phenomenon is rather obvious when deviations of the latter two indices from the HPI are greater. The corrective behavior of the HPI is more notable under these circumstances.     

The calculation of capital requirement using Extreme Value Theory

The Basel Committee has suggested some formulas for calculating capital requirement using the Advanced Internal Ratings-Based Approach. However, these formulas were derived under the assumption of a normal distribution. Thus, the capital requirement estimated by the Basel formula may be incorrect when the asset distributions are not normal. Using an analysis of qualifying revolving retail exposures as an example, this paper introduces a formula based on the Extreme Value Theory to calculate the capital requirement. This formula is more general and accurate than its predecessors, because it can be used with any type of distribution. Numerical examples are provided to demonstrate that the capital requirement estimated by the Basel formula is less than by our formula when the asset distribution has a heavy tail, and more than by our formula when the distribution has a short tail. Our formula is also more sensitive to risk than competing models in the context of the recent financial crisis.     

Government websites for promoting East Asian culinary tourism: A cross-national analysis

The content of government tourism websites is very important for promoting a tourist destination's exciting cuisine and food culture. These websites help to shape a country's, region's or locality's culinary-cultural image; they create a virtual experience for culinary tourists. This study explores the contents of the cuisine and gastronomy websites of Hong Kong, Japan, Korea, Singapore, Taiwan and Thailand, analyzing the techniques used to introduce and promote these East Asian tourist destinations' cuisine and food culture. Specifically, the researchers examined the capacity of government websites to introduce and advertise traditional and local foods, restaurants, gastronomic tours, recipes and culinary cultures (including table manners and other dining customs). They also looked more generally at culinary tourism marketing strategies, including the use of restaurant guides and certifications.
