Portfolio selection in this paper is done in an agent-based setting with individuals communicating through the social network. We explained why different individuals possess different portfolios in time and why portfolios change with the change of the environment. The developments of the games...

I present a dynamic investment model in which mutual funds' inferior performance is an equilibrium response to incentives rather than the consequence of low skills. In the model, a skilled (informed) manager responds to investors' flows, which are a convex function of performance relative to...

We examine how third party ratings and mandatory benchmark disclosure affect aggregate risk adjustment by retail investors. Morningstar changed its ratings methodology in June 2002. Before the change, the ratings were based on a risk-adjusted performance ranking of all US equity funds and highly...

We show that benchmark-linked convex incentives can lead risk-averse money managers aware of mispricing to over-invest in overpriced securities. In the model, the managers' risk-seeking behavior varies in response to the interaction of mispricing with convexity and benchmarking concerns....

We present a new profitable trading and risk management strategy with transaction cost for an adaptive equally weighted portfolio. Moreover, we implement a rule-based expert system for the daily financial decision making process by using the power of spectral analysis. We use several key...

While international portfolios are still heavily biased towards home assets, the home bias has exhibited a clear downward trend in the last few decades. Interestingly, the underlying rise in foreign investment has been primarily directed to just a handful of OECD countries, and has not given...

We consider an optimal risk-sensitive portfolio allocation problem accounting for the possibility of cascading defaults. Default events have an impact on the distress state of the surviving stocks in the portfolio. We study the recursive system of non-Lipschitz quasi-linear parabolic HJB-PDEs...

This paper investigates how a profit-maximizing asset originator can coordinate the information acquisition of investors with different expertise by means of asset bundling. Bundling is beneficial to the originator when it discourages investors from analyzing idiosyncratic risks and focuses...

Does textual complexity affect attention and market outcomes? I conduct a global field experiment with Seeking Alpha that randomly assigns to investors different titles for the same news article. Investors are less likely to open the articles when titles are more complex---scored quantitatively...
