This paper analyzes the relation between exogenous changes in commodity export prices and the real exchange rate in a monetary economy. The traditional Dutch?Disease case is extended, and the monetary consequences of an export boom are explored. It is shown that commodity export booms can...

In this paper a model that analyzes the interaction between changes in commodity export prices, money creation, inflation, and the real exchange rate in a developing country is developed. The model is then tested using data for Colombia. A number of experts have argued that the fluctuations of...

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

This paper explores role of product adding and dropping within manufacturing firms over the business cycle. While a substantial body of work has explored the importance of the extensive margins of firm entry and exit in employment and output flows, only recently has research begun to examine the...

Product redesigns happen across virtually all types of products. While there is substantial evidence that new varieties of goods increase welfare, there is little evidence on the effect of product redesigns. We develop a model of redesign and exit decisions in a dynamic oligopoly model (a la...

We build a theoretical model of multi-product firms that highlights how competition across market destinations affects both a firm's exported product range and product mix. We show how tougher competition in an export market induces a firm to skew its export sales towards its best performing...

This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to irreversible investment costs. The...

This paper examines the frequency, pervasiveness and determinants of product switching among U.S. manufacturing firms. We find that two-thirds of firms alter their mix of five-digit SIC products every five years, that one-third of the increase in real U.S. manufacturing shipments between 1972...

Products often bundle together many functions e.g., smartphones. The firm develops the big idea (which functions to bundle) and then chooses one supplier per function. We develop a model featuring holdup in which the firm's bargaining power declines in the number of suppliers. Greater scope as...

We investigate how firms adapt to trademark protection, an extensively used but underexamined form of IP protection, by exploring a historical precedent: China's trademark law of 1923---an unanticipated and disapproved response to end foreign privileges in China. By exploiting a unique, newly...
