Recent research reveals that hedge fund returns exhibit a range of different,possibly non-linear pay-off patterns. It is difficult to qualify all these patternssimultaneously as being rational in a traditional framework for optimal financial decisionmaking. In this paper we present a simple...

We propose a new approach for estimating mutual fund performance that simultaneously controls for both factor exposure and firm characteristics. This double-adjusted alpha is motivated by the recent findings that traditional Fama-French style factor models do not fully adjust returns for the...

A number of recent theoretical studies have explored trading in fragmented markets, e.g. Biais etal. (2000), a phenomenon increasingly witnessed in modern markets. The key assumptiongenerating the results is that there is at least one liquidity demander exploiting access to allmarkets by...

This paper provides an empirical description of the relationshipbetween the trading system operated by a stockexchange and the transaction costs faced by heterogeneous investors who use the exchange. Therecent introduction ofSETS in the London Stock Exchange provides an excellent opportunity...

We develop a new likelihood-based approach to sign trades in the absence of quotes. It is equally efficient as existing MCMC methods, but more than 10 times faster. It can deal with the occurrence of multiple trades at the same time, and noisily observed trade times. We apply this method to a...

I revisit the Diamond-Dybvig model of liquidity insurance in the presence of hidden trades. The key result is that in this environment deposit-taking banks are not necessary for the efficient provision of liquidity. Mutual funds are constrained efficient when supplemented with the same...

I analyze welfare properties of mutual funds in the Diamond-Dybvig model with two sources of aggregate risk: undiversifiable interest rate risk and shocks to aggregate liquidity demand. Mutual funds are inefficient when the economy faces undiversifiable interest rate risk. However, if only...

By holding assets longer and increasingly focusing on growth strategies private equity firms enter the territory of strategic buyers. In one such strategy, a private equity firm buys a company and then builds on that "platform" through add-on acquisitions. We ask whether such serial...
