Link analysis: Hyperlink patterns and social structure on politicians’ Web sites in South Korea

This paper presents results of an investigation into political communication expressed by links connecting politicians’ web sites with the sites of other political actors in South Korea. Additionally, this study examines whether a set of socio-demographic variables for web site producers is associated with linking behavior. Both traditional methods and social network analytical techniques are employed to investigate linking patterns between sites. Perhaps unsurprisingly, members of the South Korean National Assembly linked most to party web sites, and linking patterns did not change between 2003 and 2004. Out of a range of demographic variables investigated, the only ones that related significantly to linking practices were party affiliations and friendship networks.     

Inferring international dotcom Web communities by link and content analysis

This study investigates international hyperlink networks and their content in terms of the .com domain, the most ubiquitous generic top-level domain, to examine the kinds of global websites that are linked to .com, what the linked contents are, and who are dealing with the hyperlinks. The results show the hyperlink network of websites with outgoing hyperlinks to .com websites indicates the dominant centrality of the U.S., whereas that of those with incoming hyperlinks from .com websites illustrates a core–periphery structure centered about the U.S. and other superpowers. The most globalized topics covered by websites linked to .com websites are business, the Internet and computers, recreation and entertainment, and personal interests. Many of the websites with outgoing hyperlinks to .com websites use only one non-English language. The predominant use of English by websites with outgoing hyperlinks to .com websites demonstrates the centrality of countries using English as the mother language in hyperlinked societies on the Web. The implications of these findings and further research are discussed.     

Regional Financial Arrangements: A Survey of the Literature and Recent Developments

This article summarizes recent studies on regional financial arrangements (RFAs) and examines the role played by global multilaterals and RFAs in emerging crises. We also review the major RFAs with regard to their basic organizational structure, activities, legal framework, and lending facilities. Finally, we discuss the attributes needed for the sustainable development of RFAs and we look at how they can expand their role for economic cooperation in the associated regions.     

Strategies of effective low share businesses

Previous research has suggested that low share market businesses have dismal prospects. This study examines low share businesses which are effective. In particular, it examines the product-market choices and competitive strategies of effective low share businesses, comparing them with two control groups: effective high share and ineffective low share businesses. Data are drawn from PIMS data bases and hypotheses are tested using cluster analysis and discriminant analysis. Effective low share businesses are found to locate in stable rather than protected environments. Their competitive strategies are strongly characterized by selective focus on specific strengths.     

Technology sourcing and output of established firms in a regime of encompassing technological change

This paper argues that when the technological basis of an industry is changing, the firm's approach to technology sourcing plays a critical role in building the capabilities needed to generate new technical outputs. Using survey and archival data from the U.S. pharmaceutical industry during the period 1981–91, we find that different approaches to technology sourcing (internal R&D and external R&D) are related to different types of biotechnology‐based output at the end of the period. Internal R&D was positively associated with patent output. Acquisition activity was positively related to number of biotechnology‐based products. Greater use of R&D contracts and licenses was associated with stronger reputation for possessing expertise in biotechnology. These findings underscore the importance of taking a multifaceted approach to technology sourcing in order to build the absorptive capacity needed to generate new technical output. Surprisingly, we also found that involvement in joint ventures was negatively related to patent output. This raises interesting questions about the strategic use of joint ventures in a regime of encompassing technological change. Copyright © 2003 John Wiley & Sons, Ltd.     

Factor supply interruption, welfare loss and shortage management

Factor supply shortage is a common problem faced by a firm. Solutions for allocating the limited supply include rationing, interruption and pricing. While previous research has examined the welfare losses generated by each solution, there is little evidence on their relative magnitudes within a common framework. The objective of this paper is to specify a model of firm behaviour under service interruption to estimate the welfare loss of service interruption. The same model is used to estimate the loss due to a price increase intended to resolve a supply shortage. Using water consumption data collected for Hong Kong, we find that relative to pricing, service interruption is inefficient for water shortage management.     

Assessing Regional Risks From Pandemic Influenza: A Scenario Analysis

We analyse the economic risks from two influenza pandemics that represent extremes along the virulence‐infectiousness continuum of possible pandemics: a high virulence–low infectiousness event and a low virulence–high infectiousness event. Our analysis involves linking an epidemiological model and a quarterly computable general equilibrium model. We find that global economic activity is more strongly affected by a pandemic with high infection rates rather than high virulence rates, all else being equal. Regions with a higher degree of economic integration with the world economy face greater risks of negative effects than less integrated regions.     

A note on deficit analysis in dependency models involving Coxian claim amounts

In this paper, we consider a fairly large class of dependent Sparre Andersen risk models where the claim sizes belong to the class of Coxian distributions. We analyze the Gerber–Shiu discounted penalty function when the penalty function depends on the deficit at ruin. We show that the system of equations needed to solve for this quantity is surprisingly simple. Various applications of this result are also considered.     

The European distaste for US budget deficits: A regime shift explanation

It is the general consensus that the chief stimulus to the European recovery from the 1982 recession was exports to the United States. It is therefore paradoxical that European official circles were critical of the swingeing US budget deficits throughout the 1980–85 period even though the budget deficits were the driving force behind the high US import demands. This paper argues that the European government had become more concerned with price stability and hence was obliged to pursue contractionary macro policies in order to offset the supply-side price pressure caused by the strong dollar. The Europeans were unhappy with the US budget deficits because they would have benefited more if the US recovery had been maintained by looser monetary but tighter fiscal policies.

The contributions of this paper are: one, showing how a standard macro model can be modified to accomadate the endogenous European policy response; and two, testing the joint hypothesis of ‘new’ European concerns and of induced contraction by examining the policy reaction functions estimated over different time periods.
