Modeling International Long-Term Interest Rates

This study investigates the relationship among interest rates on the long-term government bonds of five industrialized countries. Both standard and new unit root tests are applied, all of which confirm the presence of exactly one unit root. New cointegration tests are also applied to these data. In contrast to previous research on short-term bonds, stock prices, and exchange rates, these results find little evidence of cointegration among the five long-term interest rate series. Thus, when modeling or forecasting these central government long-term bond yields, one may assume separate sets of fundamentals and difference the data to achieve stationarity. An error correction model may not be appropriate.     

An Integrated Model of the Adoption and Extent of E-Commerce in Firms

This work aims to explain firms’ decisions to adopt Internet-based e-commerce, and the extent to which the adopters subsequently implement e-commerce to commercialize their products and services. We examine various types of factors previously considered by the literature (competitive environment, organizational characteristics, strategic orientation, innovative capacity, managers’ characteristics, IT equipment possessed and the use made of it). The analytical model developed here on the basis of a sample of 2,038 firms suggests that the factors influencing the adoption decision are different from those that eventually influence the results of firms’ commercial operations on the Internet. Likewise, we discuss the contribution of each type of determinant and the implications.      

To merge or not to merge: That is the question

In this paper we analyze the implementation of socially optimal mergers when the regulator is not informed about all parameters that determine social and private gains from potential mergers. We show that implementation requires a certain degree of agreement between social and private incentives. The most important example where this congruence is present is when the uncertainty refers to cost savings, because in this case society and firms want costs savings to be as high as possible. Then, it is possible to induce firms to truthfully reveal the costs savings induced by the merger.Received: 7 June 2001, Accepted: 14 June 2004, JEL Classification: D78, L13, L41This paper was presented at the First CODE meeting held in Barcelona, June 1997 and in seminars at the universities of Alicante, Caen, Carlos III, Bilbao, Complutense (Madrid) and Málaga.

The Arbitration of Labor Disputes in China Today: Definition and Implications

Over the past 12 years China has strongly encouraged the use of a formalized arbitration process to resolve, among other conflict areas, labor disputes. Using a formal resolution process is meant to calm labor unrest by giving employees both individual and collective voices in workplace issues. Ultimately, China recognizes that, as did the United States with passage of the National Labor Relations Act, giving employees voice quells potential social revolution and helps business by making use of employee ideas while attracting the best employees. This paper discusses some history of the Chinese labor dispute resolution process and its specific provisions promulgated in two laws and a set of regulations. Strengths and weaknesses of the process are enumerated and the importance of the process to foreign investors, employers, and employees is laid out.     

REINVESTED EARNINGS ON DIRECT FOREIGN INVESTMENT

Reinvested earnings on direct foreign investment are accounted for differently in A System of National Accounts 1968 and the System of National Accounts 1993. In this paper these treatments are compared in relation to the connection between national income accounting and macroeconomic theory. For this purpose, macroeconomic modelling is represented by an attempt to extend the closed-economy Cambridge model of growth and distribution to a two-country trading world.     

Operations Research in passenger railway transportation

In this paper we give an overview of state-of-the-art Operations Research models and techniques used in passenger railway transportation. For each planning phase (strategic, tactical and operational), we describe the planning problems arising there and discuss some models and algorithms to solve them. We do not only consider classical, well-known topics such as timetabling, rolling stock scheduling and crew scheduling, but we also discuss some recently developed topics such as shunting and reliability of timetables.
Finally, we focus on several practical aspects for each of these problems at the largest Dutch railway operator, NS Reizigers.     

The Solvency II Process: Overview and Critical Analysis

As early as the 1970s, European Union (EU) member countries implemented rules to coordinate insurance markets and regulation. However, with the more recent movement toward a general single EU market, financial services regulation has taken on new meaning and priority. Solvency I regulations went into effect for member nations by January 2004. The creation of risk-based capital standards, the main focus of Solvency II, now appears likely sometime after 2007. The purpose of the discussion presented here is to outline the specifics of Solvency II as they currently stand and suggest important areas of future research.
