A variety-increasing view of the development of the semiconductor industry in Taiwan

The development of the semiconductor industry depends on its interactions with the environment. Developing countries face more constraints and the environmental interactions seem more complicated. The development process of the semiconductor industry could be better understood with regard to the interactions and social changes. This study proposes a variety-increasing viewpoint based on the concepts of variety increasing and internal learning to analyze the developmental experience of the semiconductor industry in Taiwan. The result shows that the development of Taiwanese semiconductor industry is a continuous variety-increasing process, which is achieved by searching and establishing successful associations in an increasingly wider and complex environment. Implications on the ongoing development of Taiwan's semiconductor industry and the development experiences of other East Asian countries are discussed.     

Extending variety seeking to multi-sided platforms: Impact of new retailer listing

This study uses theories of variety seeking to examine how a new retailer listing on a multi-sided platform (MSP) affects consumer buying behavior. Using a unique dataset from an online MSP, we evaluate changes in purchase frequency with individual retailers after a new one is listed. Contrary to expectations, the results indicate that consumers increase their purchase frequency at existing retailers. Moreover, compared to consistency seekers, variety-seeking consumers show a higher positive effect as they buy even more. This result is observed for retailers in both competing and non-competing product categories. Finally, we discuss the theoretical contributions and implications for MSPs and retailers.     

But are they Meritorious? Genetic Productivity Gains under Plant Intellectual Property Rights

The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit/yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using varietal trial data from Washington State. As the private open‐pollinated varieties exist only because of PVP and are higher yielding, these results indicate a clear public benefit from PVP.     

An Analysis of Assortment Choice in Grocery Retailing

Consumers in grocery retailing commonly buy bundles of products to accommodate current and future consumption. When all products in a particular bundle share common attributes (and are selected from the same product category), the consumer is said to assemble an assortment. This research examines the impact of assortment variety on the assortment choice process. In particular, we test the prediction that consumers demand less variety for higher quality items. To investigate this relationship, we employ a flexible choice model, suitable for the analysis of assortment choice. The model, based upon the assumption that the utility of purchase of one item in an assortment depends upon the set of items already selected, allows for a general utility structure across the assortment items. We apply the model to household assortment choice histories from the yogurt product category. Substantively, we show that yogurt choice is affected by brand quality perceptions (quality-tier competition). Moreover, we show that reaction to reductions in variety (number of yogurt flavors) is mediated by brand quality perceptions. Taken together, these empirical facts paint a picture of a consumer who is willing to trade-off variety against product quality in assortment choice.     

宋代牡丹品种和数目研究之三

我国现存7种宋代牡丹谱录中所记载的牡丹品种，经综合整理统计其数目有191个（陈平平，1999）。此外，一些宋人著作中还记载有若干上述诸谱录中未曾收入的宋代牡丹品种，经综合整理统计、较可靠者其数目有55个。两项合计宋代牡丹品种数目有246个。这一数字更加充分的证实我国是牡丹栽培和育种的古老中心。

ADOPTION AND PRODUCTIVITY IMPACT OF MODERN RICE VARIETIES IN BANGLADESH

Technological progress has helped Bangladesh to achieve self‐sufficiency in rice production in 2001 from a heavy import‐dependence, despite doubling of population and a reduction in arable land since its independence in 1971. As the adoption of modern varieties (MV) of rice is reaching a plateau, particularly for the irrigated ecosystem, an important issue is whether the research system will be able to sustain the growth of production. The present paper addresses the following questions: (i) to what extent farmers have been replacing the old MV with the new MV, and (ii) what has been the impact of the variety replacement on productivity and profitability. How crucial is the continuous research and release of improved rice varieties toward improving farm production and income for farmers comes out as a clear message to policymakers from the current paper.     

A variety-expansion model of growth with external habit formation

This paper introduces consumption externalities into one of the base line models of growth in which continuing expansion of product variety sustains long-term growth. We assume that consumers set a benchmark stock of consumption for each good so that there are commodity-specific external effects. Each good is produced by a monopolistically competitive firm and the firm exploits the presence of consumption external effects in determining its profit-maximizing price. Given those settings, we show that the introduction of consumption externalities may affect the balanced-growth characterization, transitional dynamics and policy effects in fundamental manners.     

Divergence in Variety Seeking: An Exploratory Study Among International Travelers in Asia

ABSTRACT

Variety seeking is a tendency in consumer behavior in which the consumer alternates between different makes of the same item in the quest for diversity. Variety seeking and exploratory behaviors help explain tourists’ consumption behavior and choice-making methods. Some studies have focused on the choice of food, restaurants, theme parks, travel activities, or destinations, but only a few have taken place within an international context. In this study, the influence of variety seeking and exploratory buying on travelers’ consumption behavior within an international context is analyzed. In essence, Asian travelers are compared with Western travelers. Several factors, which help explain divergence in variety seeking, are included in the analysis. The results demonstrate that variety seeking and an exploratory tendency have a significant relationship with travelers’ consumption behavior (for both Asian and Western travelers). In general, customers who have a high tendency for variety seeking are less loyal; however, there is no discernible difference between Asian and Western tourists in this regard.     

我国贸易多样性的收益分析和影响因素——基于内延边际与外延边际的考察

本研究以我国贸易多样性为研究对象,通过多国模型阐述了贸易自由化可增加多样性贸易福利;基于Feenstra(1994)的贸易多样性指数,本文给出了1995~2007年我国贸易扩张的内延边际和外延边际,2001年之后贸易的外延边际(多样性扩张)带来的贸易收益十分显著。实证结果表明,人均收入的跨国差异不利于贸易多样性的扩张,关税和非关税壁垒同样成为我国进口多样性的阻力因素,而中小企业群体规模对贸易多样性扩张的贡献作用显著。
