Although structural constraints such as model order and time delay have been incorporated in the continuous time system identification since its origin, the constraints on the estimated model parameters were rarely enforced. This paper proposes a continuous time system identification approach...

The inclusion of spatial correlation of house price in hedonic pricing model may produce better marginal implicit price estimate(s) of the environmental variable(s) of interest. Most applications where a spatial econometric model is applied to the estimation of a hedonic property value model...

The dissertation consists of two major components on the topic of environmental valuation using spatial hedonic pricing models.The first component deals with the specification of a spatial hedonic model. The focus is on how to include the spatial effects of observed house prices into a hedonic...

Essay 1: Integrated Conditional MomentTest for Parametric Conditional Distributions (with Herman J. Bierens)This paper extends the Integrated Conditional Moment (ICM) test for the functional form of nonlinear regression models to tests for parametric conditional distributions. This test is...

Rivals may voluntarily share Research and Development (R&D) results even in the absence of any binding agreements or collusion. In a model where rival firms engage in non-cooperative independent R&D process, we used optimization and game theory analysis to study the equilibrium strategy of the...

The dissertation tries to analyse the development of economic relationship, especially international trade relationship between the EU and China. Most important is, with accession into the WTO, China's tariff rate is reducing greatly. Using a computerable general equilibrium model, the...

This thesis examines a number of issues regarding the Mortensen-Pissarides search and matching model’s empirical performance. Chapter 1 documents the volatility puzzle with the Canadian data. The combined data from both Canada and the United States present an additional difficulty. Even if the...

Modeling portfolio credit risk involves the default dependencies between the individual securities in a portfolio. The copula is a common approach to construct it. It parameterizes the joint distribution of individual defaults independently of their marginal distributions. The current market...
