The key idea of this model is that firms are the result of an evolutionary process. Based on demand and supply considerations the evolutionary model presented here derives explic...
A quantum mechanical model for the relationship between stock price and stock ownership
quantum mechanical model relationship between stock price stock ownership
2012/9/14
The trade of a fixed stock can be regarded as the basic process that measures its momentary price. The stock price is exactly known only at the time of sale when the stock is between traders, that is,...
A CB (corporate bond) pricing probabilities and recovery rates model for deriving default probabilities and recovery rates
Government Bond (GB) model Corporate Bond (CB) model Term Structure of Default Probabilities (TSDP) Recovery Rate (RR) Credit Default Swap (CDS) business portfolio, credit risk management
2012/9/14
In this paper we formulate a corporate bond (CB) pricing model for deriving the term structure of default probabilities (TSDP) and the recov-ery rate (RR) for each pair of industry factor and credit r...
A No-Arbitrage Model of Liquidity in Financial Markets involving Brownian Sheets
No-Arbitrage Model Financial Markets Brownian Sheets
2012/9/14
We consider a dynamic market model where buyers and sellers submit limit orders. If at a given moment in time, the buyer is unable to complete his entire order due to the shortage of sell orders at th...
Statistical foundation of the pairwise interaction model of the stock market
Statistical foundation interaction model stock market
2012/9/14
Financial markets are a classical example of complex systems as they are compound by many interacting stocks. As such, we can obtain a surprisingly good description of their structure by making the ro...
Binomial Tree Model for Convertible Bond Pricing within Equity to Credit Risk Framework
Binomial Tree Model Bond Pricing Credit Risk
2012/9/14
In the present paper we fill an essential gap in the Convertible Bonds pricing world by deriving a Binary Tree based model for valuation subject to credit risk. This model belongs to the framework kno...
A Compact Mathematical Model of the World System Economic and Demographic Growth, 1 CE - 1973 CE
economic macrodynamics demographic macrodynamics superexponential growth power-law behavior complex systems finite-time singularity the World System
2012/9/14
We propose an extremely simple mathematical model that is shown to be able to account for more than 99 per cent of all the variation in economic and demographic macrodynamics of the world for almost t...
Finite quantum mechanical model for the stock market
quantum mechanical model stock market
2012/9/14
The price of a given stock is exactly known only at the time of sale when the stock is between the traders. If we know the price (owner) then we have no information on the owner (price). A more genera...
High-order short-time expansions for ATM option prices under a tempered stable Lévy model
Exponential Levy models CGMY and tempered stable models short-time asymptotics at-the-money option pricing implied volatility.
2012/9/14
The short-time asymptotic behavior of option prices for a variety of models with jumps has received much attention in recent years. In the present work, a novel second-order approximation for ATM opti...
A multi-agent nonlinear Markov model of the order book
A multi-agent nonlinear Markov model order book
2012/9/14
We introduce and treat rigorously a new multi-agent model of the limit order book. Our model is designed to explain a behavior of the market when new information a ecting the market arrives. Our model...
A Test of the Adaptive Market Hypothesis using Non-Bayesian Time-Varying AR Model in Japan
Adaptive Market Hypothesis Non-Bayesian Time-Varying Autoregressive Model Market Efficiency Long-Run Multipliers Kalman Smoothing
2012/9/14
This paper examines the adaptive market hypothesis of Lo (2004, 2005) using the Ito and Noda’s (2012) non-Bayesian time-varying AR model in Japan. As shown
in Ito and Noda (2012), their degree of mar...
Conditional sampling for barrier option pricing under the Heston model
Conditional sampling barrier option pricing Heston model
2012/9/14
We propose a quasi-Monte Carlo algorithm for pricing knock-out and knock-in barrier options under the Heston (1993) stochastic volatility model. This is done by modifying the LT method from Imai and T...
Operational risk is the risk relative to monetary losses caused by failures of bank internal processes due to heterogeneous causes. A dynamical model including both spontaneous generation of losses an...
Microscopic understanding of heavy-tailed return distributions in an agent-based model
Microscopic understanding of heavy-tailed return distributions agent-based model
2012/9/14
The distribution of returns in nancial time series exhibits heavy tails. In empirical studies, it has been found that gaps between the orders in the order book lead to large price shifts and thereby ...
On the role of backauditing for tax evasion in an agent-based Econophysics model
backauditing tax evasion agent-based Econophysics
2012/9/14
We investigate an inhomogeneous Ising model in the context of tax evasion dynamics where dif-ferent types of agents are parametrized via local temperatures and magnetic fields. In particular, we analy...
