This paper deals with applying GIS and spatial statistics to hedonic modeling. More precisely, it looks at spatial autocorrelation and trend surface analysis (TSA) as devices that can be used to improve model performances. Empirical analysis is performed on the Charlesbourg 1986-87 bungalow...

This paper presents a simulation procedure that uses GIS technology for integrating accessibility to services and working places in order to improve modeling of houses values. Most real estate models use simple functions of distance to CBD in order to evaluate access to services and centrality....

In a model where agents have unequal production skills and different preferences, we build social welfare functions which rely only on ordinal non-comparable information on individual preferences. Social welfare functions are required to satisfy properties of compensation for inequalities in...

This paper implements a variety of robust, regression-based diagnostics to nonlinear models of effective federal individual income tax. The paper proposes a generalized nonlinear model of effective income.

We analyze a multistage stochastic asset allocation problem with decision rules.

We propose a stochastic programming approach for quantitative analysis of supply contracts, involving flexibility, between a buyer and a supplier, in a supply chain framework.

This paper is a user' guide to a set of Guss procedures developed at the Bank of Canada for estimating regime-switching models. The procedure can estimate relatively quickly a wide variety of switching models and so should prove useful to the applied researchers. Sample program listings are...

We present a general framework for understanding the transition from local regular to global irregular (chaotic) bahaviour of nonlinear dynamical models in discrete time. The fundamental mechanism is the unfolding of quadratic tangencies between the stable and the unstable manifolds of periodic...
