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)...

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...

Many empirical studies require estimating how consumers substitute across differentiated products. Examples can be found in a wide range of fields of economics, including environmental economics, health care economics, industrial organization, and international trade. In this paper, I propose a...
