An Euler condition for optimal inventory accumulation is used to obtain information on the behavior of mark ups of price over marginal cost in U.S. manufacturing and trade. Data at the two-digit SIC level are used. Mark ups appear to be procyclical in most of the two-digit SIC sectors.  1997 Elsevier Science S.A.

We explore the consequences of international trade in an economy that encompasses technology choice and an endogenous distribution of mark-ups due to credit market frictions. We show that in such an environment a gradual opening of trade may —but not necessarily must —have a negative impact on productivity and overall output. The reason is that the pro-competitive effects of trade reduce mark-u...

Research into computerized storage and retrieval of pictorial information has grown from modest beginnings in the late 1970's to a thriving field encompassing areas as diverse as digitized maps, satellite images, fingerprint collections, and libraries of engineering or architectural drawings. As more and more applications have been developed, the limitations of conventional retrieval methods ha...

This paper presents empirical evidence about the relationship between market openness and markup distribution of manufacturing firms. The empirical analysis uses a panel data set of Spanish firms in the period 1990-2005, with a structural approach that lets us to identify individual mark-ups. The results point out that tougher competition associated to openness reduces the average of marginal c...
