In an example where some bidders have superadditive values, we characterize the equilibria of a simultaneous ascending auction and compare the revenue and efficiency generated with ones generated by the sequential, the one-shot simultaneous, and the Vickrey-Clarke-Groves auctions.

This paper proposes an empirical test of several hypotheses linking age, order of entry, and strategic orientations to a firm's performance. Three strategies are defined: cost-leadership strategy, innovative differentiation, and marketing differentiation The aim is to show that the impact on performance of both age and each of the three strategic orientations may differ according to a firm's order of entry into an industry. Following Lieberman and Montgomery's (1998) evaluation of their major contribution on first mover advantage, we emphasize three points. First, we develop and lest hypotheses related to early and late followers' strategic orientations, broadening the scope of traditional studies on pioneers. Second, the model combines the dimensions of a firm's age, order of entry, and strategic orientations, as well as industry conditions (stage of the industry, environmental unpredictability, and technology diffusion), to establish a contingent model of performance analysis. Finally, the empirical study deals chiefly with organizational performance and not market share, which is considered a typical advantage accruing to pioneers.In addition, the scope of the study (582 French manufacturing firms) provides the means to fill a void in empirical studies because it is a broad cross-sectional test on non-U.S. data. The firms are mainly private, small to medium-sized, and single or dominant business firms. Therefore, our assumptions must be understood as particularly applicable to this type of firm

Culture and Career Advancement in Europe: Promoting Team Players vs. Fast Trackers

This paper reports the results of a study of the cultural influences on career systems and job promotion. The authors report the conclusions reached during the first phase of a large European study on managerial decision-making. Nearly 300 managers participated in this phase, which surveyed 25 firms from the financial sectors of France, Germany, Italy, Spain, and the United Kingdom. Models built upon Sonnenfeld and Peiperl's career typology and on Derr and Evans et al. cultural career maps are examined. The results of this study indicate that nationality is a good determinant of the choice of internal or external promotion systems. It also finds that individual self-interest remains an important factor in managerial decision-making. The authors conclude that human resource programs designed to standardise career management policy across Europe may fail because of intentional and unintentional barriers.

Equivariant Elliptic Cohomology and Rigidity


American Journal of Mathematics

Equivariant elliptic cohomology with coriplex coefficients was defined axiomatically by Ginzburg. Kapranov and Vasserot and constructed by Grojnowski. We give an invariant definition of complex S1-equivariant elliptic cohomology, and use it to give an entirely cohomological proof of the rigidity theorem of Witten for the elliptic genus. We also state and prove a rigidity theorem for families of elliptic genera.
