Late and multiple bidding in second price Internet auctions: Theory and evidence concerning different rules for ending an auction

In second price Internet auctions with a fixed end time, such as those on eBay, many bidders submit their bids in the closing minutes or seconds of an auction. We propose an internet auction model, in which very late bids have a positive probability of not being successfully submitted, and show that late bidding in a fixed deadline auction can occur at equilibrium in auctions both with private values and with uncertain, dependent values. Late bidding may also arise out of equilibrium, as a best reply to incremental bidding. However, the strategic advantages of late bidding are severely attenuated in auctions that apply an automatic extension rule such as auctions conducted on Amazon. Field data show that there is more late bidding on eBay than on Amazon, and this difference grows with experience. We also study the incidence of multiple bidding, and its relation to late bidding.     

Teaching versus research: A multi-tasking approach to multi-department universities

We study the possible implications of incentive schemes as a tool to promote efficiency in the management of universities. In this paper, we show that by designing internal financial rules which create yardstick competition for research funds, a multi-department university may induce better teaching quality and research, as compared to the performance of independent departments.     

JOB MOBILITY IN BRITAIN: ARE THE SCOTS DIFFERENT? EVIDENCE FROM THE BHPS†

The Scottish extension‐sample of the British Household Panel Study (BHPS) is used to shed light on differences in job mobility patterns in England and Scotland for both men and women. Based on probit estimates of the overall mobility rate, a new decomposition technique is applied to distinguish between explained and unexplained differences. Furthermore, exploiting data on the number of job changes, a zero inflated Poisson model is estimated to provide information on possible differences in the expected number of job changes. Overall, there is evidence that suggests significant differences in mobility patterns south and north of the Borders; however, this is confined to men. Yet, whether this suffices to justify a heterogeneous regional labour market remains to be seen.     

The impact of productivity adjusted deviations from PPP on the U.S. inbound FDI: Evidence from Japan, U.K. and Germany

In this paper, we investigate the degree to which productivity adjusted deviations from PPP influence the U.S. inbound FDI. Our results show a significant negative relationship between productivity adjusted misalignments and the U.S. inbound FDI from Germany and the United Kingdom in the short-run, and a positive relationship in the long-run. Hence, indicating that a positive misalignment—undervalued U.S. dollar—leads to a decrease in the U.S. inbound FDI in the short-run and to an increase in the long-run. No significant evidence is found for Japan. Interestingly, unadjusted real exchange rate changes show no statistically significant relationship with respect to the U.S. inbound FDI. The authors thank the reviewers for their insightful comments.     

Globalisation, the global village and the civil society

Human dynamics, institutional change, political relations and the global environment have become increasingly intertwined. The development of multicultural societies has certainly not been without its problems. The re-emergence of extremist political parties, the segregation of cultures and ethnic conflict, illustrate the problematic side of socio-cultural integration at the local level. We argue that socio-cultural factors not only change as a result of globalisation, but also can be causes, as well as challenges to the process of globalisation itself. We describe how the recent introduction of the MGI and KOF globalisation indices can be used to empirically address to what extent globalisation affects social phenomena. Overall, while the rigidity of national boarders slackens, to speak about a global community is misleading. National borders still exist and the nation-state still matters. The fact is that they have to co-exist with civil society. The institutions of global civil society place limits upon the government and function as a sort of check on various forms of government, especially the authoritarian and absolutist varieties.     

Integrated models of capital adequacy – Why banks are undercapitalised

With the majority of large UK and many US banks collapsing or being forced to raise capital over the 2007–9 period, blaming bankers may be satisfying but is patently insufficient; Basel II and Federal oversight frameworks also deserve criticism. We propose that the current methodological void at the heart of Basel II, Pillar 2 is filled with the recommendation that banks develop fully-integrated models for economic capital that relate asset values to fundamental drivers of risk in the economy to capture systematic effects and inter-asset dependencies in a way that crude correlation assumptions do not. We implement a fully-integrated risk analysis based on the balance sheet of a composite European bank using an economic-scenario generation model calibrated to conditions at the end of 2007. Our results suggest that the more modular, correlation-based approaches to economic capital that currently dominate practice could have led to an undercapitalisation of banks, a result that is clearly of interest given subsequent events. The introduction of integrated economic-scenario-based models in future can improve capital adequacy, enhance Pillar 2’s application and rejuvenate the relevance of the Basel regulatory framework.     

Firm wage differentiation in Eastern GermanyA non-parametric analysis of the wage spread

In Eastern Germany, wage differentiation between firms has clearly grown, parallel to individual wage differentials. Nevertheless, the wage spread between firms is still much less than in Western Germany. In this paper, a non‐parametric decomposition is used to analyze the difference between the wages spread in the two parts of Germany. Only part of the difference can be explained by different economic structures in Eastern Germany. By far, the greater part of the difference in the wage spread between firms in the two parts of the country is due to the fact that differences in wages paid by firms of the same type in Eastern Germany are much less than those of their counterparts in Western Germany. A striking result of the analysis is that the gap in the wage variance between Eastern and Western Germany is increasing.     

THE EFFECTS OF PRESENTATION FORMAT ON THE EFFECTIVENESS AND EFFICIENCY OF AUDITORS‘ ANALYTICAL REVIEW JUDGMENTS

Modern audit practice has focused increasing attention on the use of analytical review procedures to improve the effectiveness and efficiency of audits. To assist in this endeavour, one branch of analytical review research has investigated the judgment processes that auditors' use in analytical review and the development of decision aids to improve these processes. Several recent papers have considered how alternative presentations of financial and operating data, specifically graphs versus tables, may affect the effectiveness of auditors' analytical review judgments. However, the results have been mixed. This study investigated the expectation that there would be effectiveness and efficiency performance advantages for auditors receiving graphically presented data over those receiving tabular presented data in an analytical review setting. This paper reports on the results of an experiment that examined the impact of graphs versus tables on the effectiveness of sales account balance prediction, confidence in this prediction and the setting of a noninvestigation region, and the relative time efficiency with which these tasks were completed, for an analytical review of sales for a retailing client. The study found mixed results for the accuracy of the sales account balance predictions of the graphical and tabular treatment groups, with no difference found when a regression model estimate of the ‘correct’ prediction was used and greater accuracy for the graphical group when the actual audited sales account balance was used as the accuracy benchmark. No significant differences between treatment groups was found for their confidence in their sales account balance predictions and the width of the noninvestigation regions set. However, a significant time advantage was found for the graphical group. These findings suggest that there may a useful role for the use of graphs as decision aids in income statement related analytical review procedures in improving audit efficiency without sacrificing audit effectiveness.
