Correlation matrices have many applications, particularly in marketing and financial economics - such as in risk management, option pricing and to forecast demand for a group of products in order to realize savings by properly managing inventories, etc. Various methods have been proposed by...

Generalized with the regime-dependent beliefs and regime-switching dynamics, the simple market-maker framework established by Day and Huang (1990) is capable to model all types of crises, that is, sudden crisis, disturbing crisis and smooth crisis, and to offer economic and dynamic...

We consider a casino gambling model with an indefinite end date and gamblers endowed with cumulative prospect theory preferences. We study the optimal strategies of a pre-committed gambler, who commits her future selves to the strategy she sets up today, and of a naive gambler, who is unaware of...

This paper proposes a new method for determining the upper bound of any investment strategy's maximum profit, applied in a given time window [0, T]. This upper bound is defined once all the prices are known at time T and therefore represents the ex-post maximum efficiency of any investment...

This research discusses the process used to develop model equity and fixed income portfolios that could, if adopted by an organization, align 100% of the assets in its endowment fund with a mission to reduce poverty in the San Francisco Bay Area. Given that endowments funds must follow fiduciary...

We propose a simple non-equilibrium model of a financial market as an open system with a possible exchange of money with an outside world and market frictions (trade impacts) incorporated into asset price dynamics via a feedback mechanism. Using a linear market impact model, this produces a...

In this paper we examine various types of financial crises and conjecture its underlying mechanisms using a deterministic heterogeneous agent model (HAM). In a market-maker framework, forward-looking investors update their price expectation according to psychological trading windows and cluster...
