GARCH modelling in continuous time for irregularly spaced time series data
GARCH modelling continuous time irregularly spaced time series data
2010/12/17
The discrete-time GARCH methodology which has had such a profound influence on the modelling of heteroscedasticity in time series is intuitively well motivated in capturing many `stylized facts' conce...
Time vs. Ensemble Averages for Nonstationary Time Series
Time Ensemble Averages Nonstationary Time Series
2010/12/17
We analyze the question whether sliding window time averages applied to stationary increment processes converge to a limit in probability. The question centers on averages, correlations, and densities...
Log-Normal continuous cascades: aggregation properties and estimation. Application to financial time-series
Log-Normal continuous cascades aggregation properties estimation Application financial time-series
2010/12/17
Log-normal continuous random cascades form a class of multifractal processes that has already been successfully used in various fields. Several statistical issues related to this model are studied. W...
Constructing the Optimal Solutions to the Undiscounted Continuous-Time Infinite Horizon Optimization Problems
Constructing Optimal Solutions Undiscounted Continuous-Time Infinite Horizon Optimization Problems
2010/12/17
We aim to construct the optimal solutions to the undiscounted continuous-time infinite horizon optimization problems, the objective functionals of which may be unbounded. We identify the condition un...
Integration I(d) of Nonstationary Time Series: Stationary and nonstationary increments
Integration Nonstationary Time Series Stationary nonstationary increments
2010/12/17
The method of cointegration in regression analysis is based on an assumption of stationary increments. Stationary increments with fixed time lag are called integration I(d). A class of regression mod...
Short-time behaviour of demand and price viewed through an exactly solvable model for heterogeneous interacting market agents
demand price viewed market agents
2010/12/13
We introduce a stochastic heterogeneous interacting-agent model for the short-time non-equilibrium evolution of excess demand and price in a stylized asset market. We consider a combination of social ...
Testing for the Markov Property in Time Series
Markov property Conditional characteristic function Generalized cross-spectrum Smoothed nonparametric bootstrap
2011/4/6
The Markov property is a fundamental property in time series analysis and is often assumed in economic and financial modelling. We develop a test for the Markov property using the conditional characte...
A Simulation Test for Continuous-Time Models
Continuous-time model Dynamic probability integral transform Generalized residuals Monte Carlo integration Simulation Transition density
2011/4/6
In this article, we propose a simulation method to implement Hong and Li’s (2005) transition density based test for continuous-time models. The idea is to simulate a sequence of dynamic probability in...
The Correlation Structure of Some Financial Time Series Models
Autocorrelations mixed ARMA models Wold representation aggregation
2010/9/7
The purpose of this paper is to examine the correlation structure of mixed autoregressive and moving average (ARMA) models, as discussed in Granger and Morris (1976). The technique we use to obtain th...

MPS Risk Aversion and MV Analysis in Continuous Time with Lévy Jumps
Risk Aversion MV Analysis temporal efficient frontier
2011/4/6
This paper studies sequential portfolio choices by MPS-risk-averse investors in a continuous time jump-diffusion framework. It is shown that the optimal trading strategies for MPS risk averse investor...

MEASURING TRENDS IN LEISURE: THE ALLOCATION OF TIME OVER FIVE DECADES
MEASURING TRENDS IN LEISURE THE ALLOCATION OF TIME FIVE DECADES
2014/3/12
In this paper, we use five decades of time-use surveys to document trends in the allocation of time within the United States. We find that a dramatic increase in leisure time lies behind t...
Nonparametric Specifiation Tests of Discrete Time Spot Interest Rate Models in China
Spot RateModels Nonparametric Speci… cation Tests Generalized residuals Probability Integral Transform Q-Stats
2011/4/6
Understanding the dynamics of spot rates is very important for asset pricing, risk
management and interest rate liberalization. We examine a wide variety of popular
spot rate models in China, includ...
