Residential Search and Mobility in a Housing Market Equilibrium Model

In this paper, we propose an equilibrium model for the housing market which provides an explanation for observed housing consumption of households over their lifetimes. The moving behavior of households is described as a stochastic dynamic process in which households moving decisions depend on information which is obtained over time. Households move when the offer exceeds an endogenously determined threshold. On the basis of the households moving behavior, the steady-state distribution of households over the housing stock is obtained. On the supply side of the market, landlords are looking for households to occupy their vacant dwellings. Their strategy is to set rents in a mixed strategy in order to profit from imperfect information. After formulating search behavior of households as well as the behavior of landlords, the market equilibrium is derived. We explore the sensitivity of the equilibrium to changes in the structural parameters.

Index Option Pricing Models with Stochastic Volatility and Stochastic Interest Rates

This paper specifies a multivariate stochasticvolatility (SV) model for the S & P500 index and spot interest rateprocesses. We first estimate the multivariate SV model via theefficient method of moments (EMM) technique based on observations ofunderlying state variables, and then investigate the respective effects of stochastic interest rates, stochastic volatility, and asymmetric S & P500 index returns on option prices. We compute option prices using both reprojected underlying historical volatilities and the implied risk premiumof stochastic volatility to gauge each model's performance through direct comparison with observed market option prices on the index. Our major empirical findings are summarized as follows. First, while allowing for stochastic volatility can reduce the pricing errors and allowing for asymmetric volatility or leverage effect does help to explain the skewness of the volatility smile, allowing for stochastic interest rates has minimal impact on option prices in our case. Second, similar to Melino and Turnbull (1990), our empirical findings strongly suggest the existence of a non-zero risk premium for stochastic volatility of asset returns. Based on the implied volatility risk premium, the SV models can largely reduce the option pricing errors, suggesting the importance of incorporating the information from the options market in pricing options. Finally, both the model diagnostics and option pricing errors in our study suggest that the Gaussian SV model is not sufficientin modeling short-term kurtosis of asset returns, an SV model withfatter-tailed noise or jump component may have better explanatory power.     

The integrability of generalized working models

This paper demonstrates the integrability of the generalized Working (1943) model as proposed by Laitinen, Theil and Raparla (1983).     

Technology transfer through technological attachés: The Belgian experience

This paper explains briefly how the economic recession was at the origin of Belgium's policy of technology transfer through technological attachés. The formal decision to start a network of attachées soon raised problems that required some profound thinking about their strategic and functional organization. This experience and the pragmatic approach that has been followed may be useful where similar initiatives are considered.

Corporate monopoly power and risk

The relationship between monopoly power and concentration may be influenced by the ‘riskiness’ of the firm. Two related issues are considered in this paper: the impact of market structure and conduct on the risk of the firm and the impact of risk upon the relationship between profitability and concentration. An a priori relationship between risk, market structure and profitability is derived within the mean-variance framework of the Capital Asset Pricing Model.     

The double dividend and the role of inequality aversion and macroeconomic regimes

The introduction of the European Community's carbon-energy tax in a small open economy is analyzed by comparing two kinds of revenue recycling. We use a dynamic general-equilibrium model with different regimes for the labor market, several income groups, and a crude valuation of environmental benefits. This allows for a more comprehensive empirical test of the double-dividend hypothesis, including equity aspects. It is shown that the weak double-dividend hypothesis can fail when equity aspects are taken into account.
