Functional Coefficient Models for Economic and Financial Data
Bandwidth selection Bootstrap Capital asset pricing model Dimensionality reduction Endogeneity Functional linear process Functional varying coefficient model Generalized likelihood ratio test Instrumental variables model Local linear estimation Locally stationary model Longitudinal data Misspecification test Piecewise stationary process Structural change model Threshold model Time-varying model Trending panel
2011/4/2
This paper gives a selective overview on the functional coefficient models with their particular applications in economics and finance. Functional coefficient models are very useful analytic tools to ...
A Unified Approach to Validating Univariate and Multivariate Conditional Distribution Models in Time Series
Diagnostic procedure Empirical distribution function Frequency domain Generalized Cramer-von Mises test Kernel method Non-Markovian process Time series conditional distribution
2011/4/2
Modeling conditional distributions in time series has attracted increasing attention in economics and finance. We develop a new class of generalized Cramer-von Mises (GCM) specification tests for time...
Exotic derivatives under stochastic volatility models with jumps
Double-barrier options volatility surface volatility derivatives forward starting options
2010/11/3
In equity and foreign exchange markets the risk-neutral dynamics of the underlying asset are commonly represented by stochastic volatility models with jumps. In this paper we consider a dense subclass...
This survey treats the problem of ruin in a risk model when assets earn investment income. In addition to a general presentation of the problem, topics covered are a presentation of the relevant inte...
The Question of Relaxation in the Wealth Exchange Models
Question Relaxation Wealth Exchange Models
2010/12/20
We look at the meaning of 'relaxation' in the wealth exchange models that are recently proposed in Econophysics to interpret the wealth distributions. To quantify and characterise the process of rela...
A path integral approach to closed-form option pricing formulas with applications to stochastic volatility and interest rate models
integral option pricing formulas applications stochastic volatility interest rate models
2010/12/20
We present a path integral method to derive closed-form solutions for option prices in a stochastic volatility model. The method is explained in detail for the pricing of a plain vanilla option. The f...
Multivariate Feller conditions in term structure models: Why do(n't) we care?
Multivariate Feller conditions structure models care
2010/12/17
In this paper, the relevance of the Feller conditions in discrete time macro-finance term structure models is investigated. The Feller conditions are usually imposed on a continuous time multivariate ...
ARCH and GARCH Models vs. Martingale Volatility of Finance Market Returns
ARCH GARCH Models Martingale Volatility Finance Market Returns
2010/12/17
ARCH and GARCH models assume either i.i.d. or (what economists lable as) white noise as is usual in regression analysis while assuming memory in a conditional mean square fluctuation with stationary ...
Continuous growth models in terms of generalized logarithm and exponential functions
Continuous growth models generalized logarithm exponential functions
2010/12/17
Consider the one-parameter generalizations of the logarithmic and exponential functions which are obtained from the integration of non-symmetrical hyperboles. These generalizations coincide to the on...
No-Free-Lunch equivalences for exponential Levy models
No-Free-Lunch equivalences exponential Levy models
2010/12/17
We provide equivalence of numerous no-free-lunch type conditions for financial markets where the asset prices are modeled as exponential Levy processes, under possible convex constraints in the use of...
The numeraire portfolio in semimartingale financial models
portfolio semimartingale financial models
2010/12/17
We study the existence of the numeraire portfolio under predictable convex constraints in a general semimartingale model of a financial market. The numeraire portfolio generates a wealth process, with...
