Since Shalit and Yitzhalit (1984) the Mean-Extended Gini (MEG) has been proposed as a workable alternative to the classical Markowitz mean-variance CAPM. Although MEG keeps under control the risk belonging to the left-tail of the return distribution, small attention is reserved to potential...

Incentive compensation induces correlation between the portfolio of managers and the cash flow of the firms they manage. This correlation exposes managers to risk and hence gives them an incentive to hedge against the poor performance of their firms. We study the agency problem between...

Textual analysis, implemented at scale, has become an important addition to the methodological toolbox of finance. In this paper, given the proliferation of papers now using this method, we first provide an updated review of the literature while focusing on a few broad topics—social media,...

Start-up entrepreneurs are often commercially inexperienced. In giving managerial advice, venture capitalists can importantly enhance the success of innovative but highly risky ventures. The supply of experienced venture capitalists is not easily increased, however. When the rate of business...

This paper puts forward an alternative approach to multiplicative models and their assessment of returns out of financial assets. Firstly, it lays down an operative definition but also sets forth a commutative framework of mappings to provide foundations to such a definition. Next, the total...

Spillover effects from equity momentum to credit markets have been shown to lead to excessive premia and, simultaneously, reduced risk measures in credit securities. Here, we present an intuitive theory for this anomaly based on the premise that equity momentum drives leverage to invoke rating...

We provide some new tools to evaluate trading strategies. When it is known that many strategies and combinations of strategies have been tried, we need to adjust our evaluation method for these multiple tests. Sharpe Ratios and other statistics will be overstated. Our methods are simple to...

A quantum financial approach to finite games of strategy is addressed, with an extension of Nash's theorem to the quantum financial setting, allowing for an entanglement of games of strategy with two-period financial allocation problems that are expressed in terms of: the consumption plans'...

We structurally estimate a model in which agents' information processing biases can cause predictability in firms' asset returns and investment inefficiencies. We generalize the neoclassical investment model by allowing for two biases -- overconfidence and over-extrapolation of trends -- that...
