A recent literature considers the identification of heterogeneous demand and supply models via "quasi … demand when one has "micro data'' linking characteristics of individual consumers to their choices. Micro data provide a … panel structure allowing one to exploit variation across consumers within each market, where latent demand shocks are fixed …

We develop an asset pricing model with flexible heterogeneity in asset demand across investors, designed to match … institutional and household holdings. A portfolio-choice model implies characteristics-based demand when returns have a factor … variables estimator for the characteristics-based demand system to address the endogeneity of demand and asset prices. Using U …

This paper provides an empirical estimate of price' and risk' elasticities of demand for term life insurance for those …

We document how demand shocks in export markets lead French multi-product exporters to re-allocate the mix of products … sold in those destinations. In response to positive demand shocks, those French firms skew their export sales towards their … multi-product firms and derive the specific demand conditions needed to generate these product-mix reallocations. These …

Among other results, we show that system-wide collateral demand is increased significantly by …

This paper examines demand systems where the demand for a good depends only on its own price, consumer income, and a … implies that such demand can take only one of two simple forms. Conversely, here we show that only weak conditions ensure that … such demand systems are integrable, i.e. can be derived from the maximization of a well-behaved utility function. This …
