Conflict, Distribution and Population Growth

This paper studies an optimal foraging model where distributive conflicts among foragers emerge from population growth. It investigates distributive rules set to resolve the conflicts. Efficient distributive rules are the ones associated with the most efficient productive decisions. Unequal societies, where the ruling class or King maximizes the surplus, engender the choice of more efficient productive combinations and to a smaller population relative to egalitarian societies.     

The influence of sponsor,servicer, and underwriter characteristics on RMBS performance

This paper assesses how the default frequencies of RMBS loan portfolios vary depending on sponsor, servicer, and underwriter characteristics. We find that the larger and healthier the sponsor of the transaction, the lower the default frequency of the securitized loans. This finding is consistent with the hypothesis that banks with a longer market perspective are less willing to risk their good reputation for a gain in short-term profits. More surprisingly, we find that there is a negative relationship between the market share of the lead underwriter and default frequency. In contrast to reputational capital theory, it appears that investment banks with high market shares in the securitization business exploit their reputational capital.     

Agile Stage-Gate Management (ASGM) for physical products

We present a qualitative study of Agile Stage-Gate Management (ASGM),: a hybrid new product development methodology that combines Agile and Stage-Gate Management (SGM) approaches for the coordination of new product development. When applied to software projects, Agile is expected to deliver reduced development times, improved resource utilization, and greater financial success. We examine whether ASGM practitioners realize similar outcomes in a sample of global firms developing complex electro-mechanical products (e.g., automobile components, railway propulsion systems, and medical devices). Our grounded theory approach articulates an understanding of ASGM through extensive interviews of experienced professionals. Our thematic analysis supports many expected benefits (i.e., speed to market, innovation enabling), but also does not encourage others, and reveals new pitfalls that deserve recognition (i.e., resource inefficiency). ASGM is not a panacea for all product development. Overall, physical product firms adopting this method can expect reduced development times and higher levels of innovation but will expend more resources to complete development projects, but a dichotomy exists. Physical product developers using ASGM experience a negative impact on project resource efficiency due to the need for dedicated resources, frequent product demonstrations, and duplicative management structures.     

Liberalization of EU telecommunications and trade: theory, gravity equation analysis and policy implications

The liberalization of telecommunications has contributed to considerable price reductions in international telephony and to rising volumes of telecommunications. This raises the issue of the economic impact of international telephony. Falling international information and transaction costs should stimulate competition and enlarge the market radius for producers in the tradables sector—this lets us to expect trade creation effects of international telecommunications; this in turn should raise output provided that more intensive international telecommunications stimulates international diffusion of knowledge or brings about trade-related specialization gains. Based on a modified gravity equation which is taking into account the role of international telecommunication volumes—based on new ITU data—we show that international telephony has a significant positive impact on trade volume: A rise of the international telecommunications volume by 10% raises trade by 2% in Europe. At the same time the coefficients of the traditional variables, GDP in the exporting and the importing country, are smaller than in traditional approaches. Thus from a policy perspective the modernization and growth of the international telecommunications network—within a system of enhanced competition—is crucial for Europe: economic integration will be reinforced. From this perspective the Lisbon Agenda is right to emphasize the importance of creating a digitally networked knowledge society.

Current account sustainability in G7 and BRICS: Evidence from a long-memory model with structural breaks

In this paper, we extend the existing literature on current account sustainability by examining the relevance of long memory and structural breaks in modelling the dynamics of current account to gross domestic product (GDP) ratios in G7 and BRICS. Unlike standard unit root tests, which have low power, especially in cases where the series is characterized by a fractional process, the long-memory approach provides an exact measure of the degree of persistence. However, long-memory models are known to overestimate the degree of persistence of the series in the presence of structural breaks. We show that regime changes do exist in both the mean and trend of the current account to GDP ratios. Thus, we test persistence allowing for both smooth and sharp breaks. Our methodology also allows any number of sharp breaks, whereas standard unit root tests only permit either one or two breaks. Hence, our approach is more general and more robust to misspecifications caused by the omission of breaks than standard methods. We show that current accounts are sustainable in both groups of countries, with the G7 and South Africa displaying long-memory behaviour.     

The empirical effects of competition on third‐degree price discrimination in the presence of arbitrage

Since Borenstein ( 1985 ) and Holmes ( 1989 ), a theoretical and empirical literature has emerged that examines the effects of competition on third‐degree price discrimination. Since transaction costs involved in conducting arbitrage are typically unobserved, empirical investigations in this area have largely been restricted to markets such as for air travel where arbitrage is difficult, if not impossible. Using an entirely novel dataset, this paper documents the effect of competition on price discrimination in the presence of arbitrage in the Canadian online sports betting market where prices for Canadian teams are higher than in the world market. I observe how the prices of Canadian teams change in real time in response to the presence of arbitrageurs that establish Canadian sportsbooks’ observable marginal opportunity costs. I exploit the existence of government betting outlets not subject to arbitrage to obtain reduced form counterfactual estimates of the extent to which competition affects price discrimination in the presence of arbitrage. In this new empirical environment, I find results consistent with the airline literature: competition reduces overall price dispersion and markups, but dispersion and markups shrink more for those in the “strong” market than the “weak” market.     

Strategic management in a new framework

The present article is concerned with strategic management as a specific field of general management. The authors analyse the nature of strategy formation in complex organizations and present some tools for improving this critical activity. Section 2 sets out with a simple terminology and framework for the analysis of strategic management. Next, an open-systems view is presented for analysing the strategic activity and a brief literature survey is added to support the concepts presented (Section 3). After discussing their own model of strategic management in complex organizations, the authors proceed to investigate the task of top managers in this specific field (Section 4). Finally, the concepts presented are confronted with specific management modes, drawn from literature reporting on German and Japanese business practice (Section 5).     

Innovations, technological specialisation and economic growth in the EU

The paper analyses the effects of innovations, technological specialisation and technology diffusion on economic growth and convergence of the EU countries from 1969 to 1998. The empirical analysis is based on a panel data model, which enables us to assess the impacts of these three factors as well as of the usual production factors on long-term economic growth, and to calculate their partial contributions to - and -convergence of labour productivities within the EU. The results show that besides capital accumulation, transferable technical knowledge is a driving force of growth for catching-up EU countries, while it is the level of Ricardian technological specialisation for advanced EU countries.A previous version of the paper was prepared while the author was a Visiting Fellow at the Directorate General for Economic and Financial Affairs, EU Commission. I gratefully acknowledge the stimulating research atmosphere at DG ECFIN and would like to thank Werner Röger and Klaus Wälde for helpful comments. Furthermore, I would like to thank Jürgen Wolters, FU Berlin, for further helpful comments at the workshop for the special issue of this journal in Brussels, February 6–8, 2004.     

A choice‐theoretic analysis of a corporate tax holiday versus a subsidy

This paper attempts to compare the effect of a corporate tax holiday with that of a subsidy on the behaviour of the individual firm. Assuming the subsidy equals the amount of tax paid by a firm operating under the subsidy system, we find that the firm's net profit will be greater under the tax holiday than under the subsidy regime. Similarly, if the subsidy exceeds the tax by an amount that would equalize the profits made by the (“marginal”) firm under the two regimes, then it is found that firms with higher than “average” unit costs would opt for the subsidy system; conversely, firms with a low cost structure would maximize profits by selecting the tax holiday. Finally, a multiperiod analysis of the particular choice facing prospective manufacturers in Ciskei, shows that the firm would normally choose the subsidy system except if the current tax exceeded the subsidy at the output level representing maximum profit under the tax holiday.
