This paper studies the effect of new fund flows on investment behavior and the resulting equilibrium price of risk. The Small Fund Industry model shows equilibria with overinvestment in unprofitable and underinvestment in profitable investment opportunities. The Large Fund Industry model derives...

Three concepts: stochastic discount factors, multi-beta pricing and mean-variance efficiency, are at the core of modern empirical asset pricing. This chapter reviews these paradigms and the relations among them, concentrating on conditional asset-pricing models where lagged variables serve as...

We present a model with dynamic investment flows, where fund managers have the ability to generate excess returns and study how forcing them to commit part or all of their personal wealth to the fund they manage affects fund risk taking. We contrast the behavior of a manager that may invest her...

Large-Scale Asset Purchases can impact the price of securities directly, when securities are targeted by the central bank, or indirectly through portfolio re-balancing of private investors. We quantify both the direct and the portfolio re-balancing impact, emphasizing the role of investor...

VaR_Delta-Normal fails in two counts: subadditivity and potentially producing losses larger than its portfolio value. This paper solves the second inconsistency developing formulas derived from a put option, named PVaR_Delta-Normal and Put_Expected_Shortfall, PSF_Delta-Normal; the latter also...

Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure and can be successfully used to construct robust portfolios that perform well during equity market drops. We start with a classical 60 percent Bonds/ 40 percent Stocks portfolio with monthly rebalancing that...

We discuss performance of some known market anomalies like equal-weighted index, low volatility stock index, factor anomalies of Andrea Frazzini, Ronen Israel and Tobias J. Moskowitz. We suggest the utilization of these anomalies through dynamic risk allocation in portfolios based on these...

Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure. A classical portfolio insurance strategy of Black-Jones-Perold can be easily implemented with leveraged ETFs. More complex dynamic portfolio strategies that also can be implemented using leveraged ETFs. We...

We propose debt-wealth constraints to separate all households into constrained and unconstrained groups. A constrained household is subject to debt payment dues with limited wealth. However, an unconstrained family has cash reserves. Since cash reserves can absorb investment losses, only...

Despite the growing interest in green investing among academics and industry professionals alike, there is little consensus on whether it successfully incentivizes firms to adopt eco-friendly business practices. Using the equity holdings of institutional investors and the “demand system...
