We build a macroeconomic model for Switzerland, the Euro Area, and the USA that drives the dynamics of several asset classes and the liabilities of a representative Swiss (defined-contribution) pension fund. This encompassing approach allows us to generate correlations between returns on assets...

We investigate the effects of introducing a central clearing counterparty (CCP) on securities prices by adopting as an experimental construct the 2009 CCP reform in three Nordic markets. We find that, relative to other European economies, these countries experience market-adjusted equity returns...

In this paper, we analyze the conflicts of interest of an informed agent who is responsible for divulging his private information about a company and has a reward function positively dependent on its stock price. We assume that the demand for the stock is subject to shocks that may increase...

I propose an arbitrage-based theory of bubbles in economies with general portfolio constraints and differences in beliefs. I find that, in general, bubbles cannot exist unless the constraints restrict the demand for credit sufficiently to induce low interest rates. Speculation due to...

We present comprehensive evidence in support of giving liquidity equal standing to size, value/growth, and momentum as investment styles, as defined by Sharpe (1992). First, we show that financial market liquidity, as identified by stock turnover, is an economically significant indicator of...

Systematic mispricing primarily affects speculative stocks and predominantly results in overpricing, predicting lower average returns. Because speculative stocks overlap with stocks deemed risky by rational models, failing to control for exposure to systematic mispricing can bias tests of...

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 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...
