Field publishing performance of U.S. economics departments

Conclusion The purpose of this study is to reduce information costs in the market for graduate education in economics and the market for Ph.D. economists by providing information on research concentration in each of 19 fields for 1980–1986. Some variation in publishing performance across fields is found in highly regarded universities. Unexpected faculty strength is discovered in some middle level departments for particular fields. Among middle- and lower-ranked departments, substantial publishing diversity across fields is evident.     

The Dynamics of Markups and Inventories in Retailing Firms

This paper is concerned with the interaction between price and inventory decisions in retailing firms and its implications for the dynamics of markups and the existence of sales promotions. We consider a model where a monopolistically competitive retailer decides price and inventories, and assumes lump-sum costs when placing orders or changing nominal prices. In this model, the existence of stockout probabilities and fixed ordering costs generate a cyclical price behaviour characterized by long periods without nominal price changes and short periods with very low prices ( i.e. sales promotions). We estimate this model using a unique longitudinal dataset with information about retail and wholesale prices, inventories, orders, and sales for several brands in a supermarket chain. Based on the estimated model we perform several counterfactual experiments that show the important role that inventories and fixed ordering costs play in the dynamics of retail prices and the frequency of sales promotions in this dataset.     

The missing equation: The wedge model alternative

This article develops an alternative method for solving the problem of the “missing equation” by including the market-nonmarket decision for factors and capital-labor mix decision for producers. The result is a wedge or supply-side model of the economy. This general equilibrium macro model describes the interaction between the product and factor markets, describes both the income and substitution effects of government actions, and provides new insights into the full impact of the government sector.
