For information/digital products, the used goods market has been viewed as a threat by producers. However, it is not clear if this view is justified because the used goods market also provides owners with an opportunity to sell their products. To investigate the impact of the used goods market...

In this paper, we develop an empirical demand model and an estimation strategy that can account for excess demand, and the unobserved component of product quality. Our methodology allows us to quantify the extent of rationing, price and quality elasticities, and shed light on the potential...

This paper develops a computationally efficient approach to the estimation of random coefficients logit model of dynamic consumer demand using product panel data. The conventional GMM estimation relies on two computationally intensive fixed point algorithms, each developed by Rust (1987) and...
