This paper examines the practice of phantom bidding in common value auctions with asymmetric information. Unlike in private value auctions it is very difficult to profit from phantom bidding even if the auctioneer observes the number of interested bidders. We find that the auctioneer is worse off submitting low bids or mixing between his participation strategies. Phantom bidding can generate higher revenues if a single bidder with a high value estimate is likely to be present at the auction. Systematic observation of an isolated high estimate requires negative correlation across bidders’ information that is atypical in a common value environment. 相似文献

Bidders who receive both “common-value” and “private-value” signals about the value of an auction prize cannot fully infer
their opponents’ information from the bidding. So bidders may overestimate the value of the prize and, subsequently, regret
winning. When multiple objects are on sale, bidding in an auction provides information relevant to the other auctions, and
sequential auctions are more vulnerable to overpayment and winners’ regret than are simultaneous auctions. With information
inequality among bidders, the seller’s revenue is influenced by two contrasting effects. On the one hand, simultaneous auctions
reduce the winner’s curse of less informed bidders and allow them to bid more aggressively. On the other hand, sequential
auctions induce less informed bidders to bid more aggressively in early auctions to acquire information.

Results of research on whether changes in earnings can predict future stock returns are inconclusive. We add to this debate by using long-term data from 1871 to 2004 to examine the predictive power of changes in earnings in periods of intrinsic bubbles and in periods absent intrinsic bubbles. Our results show that accounting for bubbles is important in whether changes in earnings can predict future stock returns. In periods of no bubble, we find that changes in earnings Granger-cause future returns, whereas in periods of bubble, this Granger causality from changes in earnings to future returns cannot be found. We conclude that changes in earnings can predict future stock returns, but only in periods absent bubbles. 相似文献

从理论和实证两方面研究全国银行间同业拆借利率对上证综指和深圳成指的影响,结果表明,利率对沪深两市的负相关变动趋势影响不够显著,原因在于我国利率还没有完全市场化、股票市场效率不高、股票市场投机氛围大于投资氛围。为促进我国股市的健康发展,政府要推进利率市场化改革,减少对人民币的管制,使人民币汇率真正市场化,央行应适时把市场利率作为我国货币政策中介目标,从而有助于实现货币政策的最终目标。 相似文献

This study applies the bootstrap panel causality test proposed by Kónya (2006. Econ Modell 23, 978) to investigate the causal link between political uncertainty and stock prices for seven OECD countries over the monthly period of 2001.01 to 2013.04. This modeling approach allows us to examine both cross-sectional dependency and country-specific heterogeneity. Our empirical results indicate that not all the countries are alike and that the theoretical prediction that stock prices fall at the announcement of a policy change is not always supported. Specifically, we find evidence for the stock price leading hypothesis for Italy and Spain, while the political uncertainty leading hypothesis cannot be rejected for the United Kingdom and the United States. In addition, the neutrality hypothesis was supported in the remaining three countries (Canada, France and Germany), while no evidence for the feedback hypothesis was found. 相似文献

This study examines the relationship between crude oil prices, US dollar exchange rates and 30 selected international agricultural prices and five international fertilizer prices in a panel framework. The study uses panel VAR methods and Granger causality tests on panel data sets of agricultural commodity prices (as well as specific agricultural commodity sub-groups) and fertilizer prices with monthly observations of the period from June 1983 to June 2013. The empirical results of the present study indicate that crude oil prices as well as US dollar exchange rates affect international agricultural commodity and fertilizer prices. Furthermore, contrary to the findings of several studies in the literature, the present study supports bidirectional panel causality effects between crude oil prices and international agricultural prices as well as between US exchange rates and international agricultural prices. 相似文献

Venture Capital Valuation,Partial Adjustment,and Underpricing: Behavioral Bias or Information Production? 下载免费PDF全文
Using a sample of venture capital (VC)‐backed initial public offerings (IPOs), we analyze the role played by perceived valuation changes on IPO underpricing. We find that perceived valuation change from the last pre‐IPO VC round to the IPO affects IPO underpricing in a nonlinear way. Further analysis indicates that information‐based theories, not behavioral biases, explain this nonlinearity. We also find that the previously documented partial adjustment effect and its nonlinear impact on IPO underpricing are related to the trajectory of the perceived valuation changes, which stands in stark contrast to prior evidence of the importance of behavioral biases. 相似文献
