摘要：This paper presents a model of an order-driven market where fully strategic, symmetrically informed liquidity traders dynamically choose between limit and market orders, trading off execution price and waiting costs. In equilibrium, the bid and ask prices depend only on the numbers of buy and sell orders in the book. The model has a number of empirical predictions: (i) higher trading activity and higher trading competition cause smaller spreads and lower price impact; (ii) market orders lead t...

摘要：Motivated by the insight of Keynes (1936) on the importance of higher-order beliefs in financial markets, we examine the role of such beliefs in generating drift in asset prices. we show that in a dynamic setting, a higher-order difference of opinions is necessary for heterogeneous beliefs to generate price drift. Such drift does not arise in standard difference of opinion models, since investors' beliefs are assumed to be common knowledge. Our results stand in contrast to those of Allen, Morr...

摘要：In this paper, we study the changes in corporate valuations induced by the adoption of the euro as the common currency in Europe. We use corporate-level data from seventeen European countries, of which eleven adopted the euro. We show that the introduction of the euro has increased Tobin's Q-ratios by 17.1% in the {euro-area} countries that previously had weak currencies. Part of the increase in corporate valuations is explained by the decrease in interest rates and by the decrease in the cost...

摘要：We propose a mechanism that relates asset returns to the firm's optimal listing choice. We use a theoretical model to show that a stock will be more liquid when it is listed on a market where similar securities are traded. We empirically examine the implications of our model using New York Stock Exchange (NYSE) and Nasdaq securities. We find that the return patterns of stocks that switch markets become more similar to the return patterns of securities listed on the new market prior to the swit...

摘要：Widespread violations of stochastic dominance by 1-month S&P 500 index call options over 1986-2006 imply that a trader can improve expected utility by engaging in a zero-net-cost trade net of transaction costs and bid-ask spread. Although precrash option prices conform to the Black-Scholes-Merton model reasonably well, they are incorrectly priced if the distribution of the index return is estimated from time-series data. Substantial violations by postcrash OTM calls contradict the notion that ...

摘要：Financial institutions around the world expected the millennium date change (Y2K) to cause an aggregate liquidity shortage. Responding to the concern, the Federal Reserve Bank of New York auctioned Y2K options to primary dealers. The options gave the dealers the right to borrow from the Fed at a predetermined interest rate. Using the implied volatilities of Y2K options and the on/off-the-run spread, we demonstrate that the Fed's action eased the fears of bond dealers, contributing to a drop in...

摘要：We present evidence on the benefits of changes in control from mergers and acquisitions. We find that the stronger the acquirer's shareholder rights relative to the target's, the higher the synergy created by an acquisition. This result supports the hypothesis that acquisitions of firms with poor corporate governance by firms with good corporate governance generate higher total gains. We also find that the synergy effect of corporate governance is shared by target shareholders and acquiring sh...
