We propose the Inverse Product Differentiation Logit (IPDL) model, a structural (inverse) demand model for differentiated products that captures market segmentation along several possibly overlapping dimensions. It generalizes the nested logit model to allow richer substitution patterns,...

Transportation networks, such as railways, roads and highways provide standard examples of natural monopolies. Since the introduction of the term “natural monopoly” by T. Malthus in 1815, this concept has been defined in different ways by several authors (F. Bastiat, J. S. Mill or L....

Full paper available at "https://ssrn.com/abstract=3141041" https://ssrn.com/abstract=3141041We first present simulations investigating some properties of the Inverse Product Differentiation Logit (IPDL) model. Next, we provide a range of general methods for building Generalized Logit (GL)...

In this paper we examine empirically the market for local amenities in the Paris metropolitan region. We find first that there is considerable inequality in the spatial distribution of these local amenities, including accessibility, environmental and social indicators. We use a spatial...

There is a growing interest in the development and the use of large-scale planning models. In this paper, we describe the first step of a project to integrate UrbanSim, a dynamic microsimulation land use model, and METROPOLIS, a dynamic traffic model. This is the first attempt, to our knowledge,...

This paper reports results of an experiment designed to analyze the link between riskydecisions made by couples and risky decisions made separately by each spouse. We estimateboth the spouses and the couples’ degrees of risk aversion and we assess how the risk preferencesof the two spouses...

This paper reports results of an experiment designed to analyze the link between risky decisions made by couples, and risky decisions made separately by each spouse. We estimate both the individuals and the couples’ degrees of risk aversion, and we analyze how the risk preferences of the two...
