This paper presents a dynamic model of the joint labor/leisure and consumption/saving decision over the life cycle. Such a dynamic model provides a framework for considering the important policy experiments related to the reforms in Social Security. We address the role of labor supply in a life...

We present a model in which the microstructure of trade in a commodity or asset is endogenously determined. Producers and consumers of a commodity (or buyers and sellers of an asset) who wish to trade can choose between two competing types of intermediaries: "middlemen" (dealer/brokers) and...

We present a new detailed data set of high-frequency observations on inventory investment by a U.S. steel wholesaler. Our analysis of the data leads to six main conclusions: orders and sales are made infrequently; orders are more volatile than sales; order sizes vary considerably; there is...

This paper estimates a dynamic model of price discrimination and inventory investment under incomplete information. The model is motivated from an empirical analysis of operations of daily observations on inventories, sales, and purchases of over 2,300 individual products by a U.S. steel...

What determines how trade in a commodity is divided between privately negotiated transactions via "middle men" (dealer/brokers) in a telephone or "dealer market" versus transactions via "market makers" (specialists) at publicly observable bid/ask prices? To address this question, we extend...

This paper studies the econometric problems associated with estimation of a stochastic process that is endogenously sampled. Our interest is to infer the law of motion of a discrete-time stochastic process {p_t} that is observed only at a subset of times {t_1,...,t_n} that depend on the outcome...
