Understanding B2B and the Web: the acceleration of coordination and motivation

This paper explores business-to-business (B2B) marketing on the Internet, and how the confluence of the two may transform the B2B landscape. Specifically, it discusses the notion of linkage value to demonstrate why the B2B phenomenon on the Internet is so significant. It then considers the mechanisms and enablers that have made the Web such an important B2B marketing channel. It also explores how the Web can reduce transaction costs, thereby facilitating more efficient exchanges and markets. The concepts of links and nodes are then introduced and the processes of disintermediation, reintermediation, disaggregation and reaggregation are explored. Finally, Web B2B configurations are considered by way of a model that describes four archetypal configurations, and the factors that are antecedent to these modes and how the Web may influence them.     

The information content of regional employment data for forecasting aggregate conditions

We consider whether disaggregated data enhance the efficiency of aggregate employment forecasts. We find that incorporating spatial interaction into a disaggregated forecasting model lowers the out-of-sample mean squared error from a univariate aggregate model by 70% at a two-year horizon.     

Overcoming underdevelopment in South Africa's second economy

This paper is a synthesis of the July 2005 Development Report published by the Development Bank of Southern Africa, Human Sciences Research Council and United Nations Development Programme (DBSA, HSRC and UNDP). The Report asks why, if the origins of economic dualism are rooted in the cheap, forced, migrant labour introduced by the mining industry and reinforced during apartheid, does dualism persist under democracy when all the relevant laws and many of the practices of the past have been abolished? The breakdown of apartheid did not immediately translate into improved material conditions for the majority of South Africans: 300 years of colonialism and 50 of internal colonialism had hard-wired a duality into the system. Two worlds, which may be conceptualised as the first and second economies, coexisted: a globally integrated world of production, exchange and consumption, and a constrained world of informality, poverty and marginalisation. This synthesis sheds light on the origin and nature of the ‘second economy’ metaphor, and suggests solutions.     

Market value effects of acquisitions involving internet firms: a resource‐based analysis

While most prior research suggests that the average change in market value of acquiring firms varies closely around zero, recent research grounded in the resource‐based view and organizational learning theory identify positive returns to acquirers. We contribute to this literature by focusing on acquisitions of Internet firms and the potential for the transfer of scarce resources. We hypothesize that acquisitions made by offline firms of Internet firms and by Internet firms of other Internet firms lead to positive market valuation for the acquirer. Results of an event study of 798 acquisitions of Internet firms provided support for these predictions. We also find that prior alliances with online firms do not reduce the gains from such acquisitions to offline firms. Copyright © 2006 John Wiley & Sons, Ltd.     

Testing Multiple Non-Nested Factor Demand Systems

This article explains how to obtain straightforward extensions of the most popular univariate non‐nested statistics, and of the RESET‐test, to a multivariate context and examines how to use these tests to compare alternative factor demand systems. The empirical application involves the classical Berndt–Khaled KLEM data set. A statistically adequate specification is determined for each competing factor demand system. The empirical results are interpreted for each system, the models are compared on the basis of multivariate paired and joint non‐nested procedures and practical indications about what to expect if these tests are applied to alternative factor demand specifications are provided.     

Observable Contracts as Commitments: Interdependent Contracts and Moral Hazard

A large literature examines the use of observable and unrenegotiable agency contracts as commitments. These analyses generally impose an ad hoc restriction that contracts cannot be contingent on one another. I relax this restriction and obtain a folk theorem. Unlike earlier folk theorems in this area, the present result applies to agency relationships that have hidden-action problems. Using an example, I also demonstrate that there are settings in which interdependent contracts support a strictly larger set of equilibrium outcomes than do independent contracts. The result highlights the critical need for careful thought about restrictions placed on the set of feasible contracts.
