The paper examines the tendency to sell winners and hold on to losers in a dynamic noisy rational expectations equilibrium with informed and uninformed investors. The key feature of the model is that the information asymmetry between investors varies over time. Besides demonstrating that the...

We construct a sentiment index with the incorporation of representative proxies in the Taiwan Stock Market and investigate the application of a cross-section of stock returns. The major contribution of the study is that the huge Chinese financial news related to each listed stock is collected...

We first develop a theory-based metric to judge the popularity of value-weighting in a stock market. We then use our metric to document that although value-weighting is less popular in emerging markets than in developed markets, its popularity is increasing almost everywhere. Finally, as we have...

We use a unique loan-level dataset to compare portfolio and securitized commercial real estate loans. The paper documents how the types of loans banks choose to hold in their portfolios differ substantially from the types of loans the same banks securitize. Banks tend to hold loans that are...

I develop a sequential trading model with ambiguity-averse market makers and provide a theoretical explanation to the historical coincidence of ambiguous events, asset illiquidity, and price variability. My model implies that the bid-ask spread of an asset contains an additive component of...

We propose a portfolio optimization approach to identifying private information. In our model, investors are exposed to liquidity and private information shocks and optimize their trading across stocks taking into account price impact (Kyle's Lambda). We obtain a very simple expression for a...

Many electricity markets exhibit an oligopolistic structure with market participants whose individual trading activities may shift prices essentially. In this context, the question of how to optimally liquidate an existing electricity futures portfolio over a fixed time horizon under the...

Banks produce short-term debt for transactions and storing value. The value of bank money must not vary over time so agents can easily trade this debt at par. This requires that no agent finds it profitable to produce costly private information about the bank's loans. To produce safe liquidity...

I examine how differences in the ability to identify profitable investment opportunities contribute to wealth inequality. I analyze a model of financial markets with investors heterogeneously informed about future returns. The unconditional wealth share distribution features a thick right-tail...

Instruments for credit risk transfer arise endogenously from and interact with optimizing behavior of their users. This is particularly true with credit derivatives which are usually OTC contracts between banks as buyers and sellers of credit risk. Recent literature, however, does not account...
