We outline a martingale duality method for determining the minimal entropy martingale measure in a general continuous semimartingale model, and provide the relevant verification results. This method is illustrated by a detailed case study of the Stein and Stein stochastic volatility model driven...

Asset prices discounted by a tradable numeraire N should be (local) martingales under some measure Q that is equivalent to the original probability measure P. Instead of studying the set of equivalent martingale measures with respect to a prespecified numeraire, we will look for a tradable...

We focus on two particular aspects of model risk: the inability of a chosen model to fit observed market prices at a given point in time (calibration error) and the model risk due to the recalibration of model parameters (in contradiction to the model assumptions). In this context, we use...

According to the advocates of a “Generalized Darwinism” (GD), the three coreDarwinian principles of variation, selection and retention (or inheritance) can be used as ageneral framework for the development of theories explaining evolutionary processes inthe socioeconomic domain. Even though...

The economic and financial variables of economic agents determine macroeconomic variables. Current models consider agents’ variables that are determined by the sums of values and volumes of agents’ trades during some time interval Δ. We call them first-order economic variables. We describe...

The purpose of this research is the development of theory on how industrial ecosystems can be driven by policy and government interventions, especially when motivated by the pursuit of “technological sovereignty” as political objective. Theoretical foundation of the research forms a...

We study the impact of bond exchange listing in U.S. publicly traded corporate bond markets. We find that listed corporate bonds have lower estimated bid-ask spreads than unlisted corporate bonds. Specifically, we show that listed bonds have estimated spreads of $0.14 lower than unlisted bond...
