Day-of-the-week effect in the Nigerian Stock Market Returns and Volatility: Does the Distributional Assumptions Influence Disappearance?
Day-of-the-week Disappearance GARCH Model Stock
2016/1/27
This study assesses the influence of error distributional assumption on appearance or disappearance of day-of-the-week effects in returns and volatility using the Nigerian stock exchange (NSE-30). The...
From Smile Asymptotics to Market Risk Measures
dynamic convex risk measures volatility skew stochastic volatility models indifference pricing backward stochastic differential equations
2011/10/9
Abstract: The left tail of the implied volatility skew, coming from quotes on out-of-the-money put options, can be thought to reflect the market's assessment of the risk of a huge drop in stock prices...
Stability of exponential utility maximization with respect to market perturbations
exponential utility maximization market perturbations Portfolio Management
2011/10/8
Abstract: We investigate the continuity of expected exponential utility maximization with respect to perturbation of the Sharpe ratio of markets. By focusing only on continuity, we impose weaker regul...
On optimal investment for a behavioural investor in multiperiod incomplete market models
Optimisation existence and well-posedness in behavioral finance distorsion Choquet integral
2011/9/30
Abstract: We provide easily verifiable conditions for the well-posedness of the optimal investment problem for a behavioral investor in an incomplete discrete-time multiperiod financial market model, ...
BSDEs in Utility Maximization with BMO Market Price of Risk
Quadratic BSDEs BMO Market Price of Risk Power Utility Maximization Dynamic Exponential Moments
2011/8/22
Abstract: This article studies quadratic semimartingale BSDEs arising in power utility maximization when the market price of risk is of BMO type. In a Brownian setting we provide a necessary and suffi...
Retailer's pricing and ordering strategy for Weibull distribution deterioration under trade credit in declining market
Finance Weibull deterioration trade credit
2010/9/21
In this research article, an ordering and pricing policy is formulated for a retailer when the supplier offers a delay in payments to settle the accounts against the retailer’s due. The problem is to ...
Unique equilibria and substitution effects in a stochastic model of the marriage market
Unique equilibria substitution effects stochastic model marriage market
2011/1/19
Choo-Siow (2006) propose a very general model for the marriage market which allows for randomly identically distributed noise in the preferences of each of the participants. The randomness is McFadden...
Replicating financial market dynamics with a simple self-organized critical lattice model
Computational Finance (q-fin.CP) Adaptation and Self-Organizing Systems (nlin.AO)
2010/11/11
We explore a simple lattice field model intended to describe statistical properties of high frequency financial markets. The model is relevant in the cross-disciplinary area of econophysics. Its signa...
Construction of the minimal entropy martingale measure in finite probability market models
Relative entropy Minimal entropy martingale measure
2010/9/13
The principle of minimization of relative entropy is used to construct a minimal entropy martingale measure for a finite probability/multiperiod market model.
Statistical identification with hidden Markov models of large order splitting strategies in an equity market
Statistical identification hidden Markov models order splitting strategies
2010/4/27
Large trades in a financial market are usually split into smaller parts and traded incrementally over extended periods of time. We address these large trades as hidden orders. In order to identify and...
Utility Maximization of an Indivisible Market with Transaction Costs
Utility optimization indivisibl emarket transaction cost continuity of valuefunction quasi-variational inequality
2010/4/27
This work takes up the challenges of utility maximization problem when the market is indivisible and the transaction costs are included. First there is a so-called solvency region given by the minimum...
Order flow dynamics around extreme price changes on an emerging stock market
Order flow dynamics price changes emerging stock market
2010/4/27
We study the dynamics of order flows around large intraday price changes using ultra-high-frequency data from the Shenzhen Stock Exchange. We find a significant reversal of price for both intraday pri...
The market behavior and performance of different strategy evaluation schemes
different strategy evaluation schemes market behavior
2010/4/27
We observe the performances of three strategy evaluation schemes, which are the history-dependent wealth game, the trend-opposing minority game, and the trend-following majority game in a stock market...
A new space-time model for volatility clustering in the financial market
space-time model volatility clustering financial market
2010/4/27
A new space-time model for interacting agents on the financial market is presented. It is a combination of the Curie-Weiss model and a space-time model introduced by J\"arpe 2005. Properties of the mo...
The level crossing analysis of German stock market index (DAX) and daily oil price time series
German stock market index daily oil price time series
2010/4/27
The level crossing analysis of DAX and oil price time series are given. We determine the average frequency of positive-slope crossings, $\nu_{\alpha}^+$, where $T_{\alpha} =1/\nu_{\alpha}^+ $ is the a...
