A Ricardo Model with Economies of Scale
Journal of Economic Theory, 1994Co-Authors: Ralph E. GomoryAbstract:Abstract This paper extends the analysis of the classical n-good two-country Ricardo model of international trade to the case where the production functions have Economies of Scale. It addresses the technical difficulties inherent in Economies of Scale by new integer programming and linear programming methods. The analysis reveals the existence of a well defined region which fills in solidly with equilibrium points as the number of goods becomes large. New economic conclusions follow from the ability to analyze these large models, among them that, in the presence of Economies of Scale, considerable conflict exists between the interests of the two trading partners.

A Ricardo model with Economies of Scale
Proceedings of the National Academy of Sciences of the United States of America, 1991Co-Authors: Ralph E. GomoryAbstract:Abstract A model of international trade that resembles the classical Ricardo model but differs from it in admitting Economies of Scale in production is described.

Economies of Scale and Natural Monopoly in the U.S. Local Telephone Industry
The Review of Economics and Statistics, 2000Co-Authors: Nakil Sung, Michael GortAbstract:This paper shows that firm-specific Economies of Scale—or net overall Economies—are correlated with subadditivity. Both Economies of Scale and subadditivity are a decreasing function of firm size. Most firms are observed to be in the relatively flat portion of the long-run average cost curve, with pronounced Economies of Scale observable only at the low end of the Scale. Economies of scope, as reflected in cost complementarities, do not appear to be a source of subadditivity. The results are estimated using translog total cost functions, and the fact that these cost functions include arguments for the quality of capital and of labor represents an innovation in methodology. © 2000 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology

External Economies of Scale and Insufficient Entry
Journal of Industry Competition and Trade, 2010Co-Authors: Arijit MukherjeeAbstract:Empirical evidence suggests that many industries are characterized by external Economies of Scale, yet the literature on the welfare effects of entry has ignored this aspect. We show that entry can be insufficient instead of excessive in the presence of external Economies of Scale. Using an example with specific demand and cost functions and Cournot competition, we show that insufficient entry occurs for any positive cost of entry and the possibility of insufficient entry increases with a higher cost of entry. Hence, anti-competitive entry regulation may not be justified in industries with strong external Economies of Scale, which may occur due to knowledge spillover.

efficiency and Economies of Scale of large canadian banks
Canadian Journal of Economics, 2007Co-Authors: Jason Allen, Ying LiuAbstract:This paper measures the Economies of Scale of Canada's six largest banks and their cost-efficiency over time. Using a unique panel data set from 1983 to 2003, we estimate pooled cost functions and derive measures of relative efficiency and Economies of Scale. The disaggregation of the data allows us to include non-traditional outputs as well as time-varying, bank-specific effects. Our model leads us to reject constant returns to Scale. These findings suggest there are potential Scale benefits in the Canadian banking industry. We also find that technological and regulatory changes have had significant positive effects on the banks' cost structure.

Efficiency, Economies of Scale and Scope of Large
2004Co-Authors: Jason Allen, Ying LiuAbstract:This paper measures Economies of Scale and scope of Canada’s six largest banks and their cost efficiency over time. Using a unique panel of data from 1983q1 to 2003q3, we estimate pooled translog cost functions and derive measures for relative efficiency, and Economies of Scale and scope. The disaggregation of the data allows us, for the first time in the literature on Canadian banks, to model banks as producing multiple outputs, including non-traditional activities. Given the long sample period of our dataset, we are able to incorporate possible technological and regulatory changes in the banks’ cost functions, as

Economies of Scale in e-Government: Time for evidence
Lecture Notes in Computer Science, 2004Co-Authors: Enrico Ferro, Marco Cantanmessa, Emilio PaolucciAbstract:The presence of Economies of Scale has been often taken for granted in the discussion of many eGovemment implementation issues. This paper discusses this assumption by showing that empirical evidence in favor of Economies of Scale may be considered context dependent. Although the analysis carried out does not lead to discard the presence of Economies of Scale in the provision of eGovemment services, it casts a new light on the concept of one-stop-shopping portals as well as providing some insights for future research.
