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… 
Social Efficiency of Entry in an Open Economy
Abstract We show that cost asymmetry between the domestic and foreign firms is not necessary for the occurrence of insufficient entry in the domestic country. This result provides a rationale for
Stackelberg Competition, Innovation and Social Efficiency of Entry
In literature, the common wisdom is that entry in an industry with homogeneous products may be socially insufficient instead of excessive in the absence of scale economies. In this paper, we formally
Free Entry, Market Diffusion, and Social Inefficiency with Endogenously Growing Demand
This paper analyzes market diffusion in the presence of oligopolistic interaction among firms. Market demand is positively related to past market size because of consumer learning, networks, and
Competition, External Economies of Scale, and Unionized Wage
Although empirical evidence shows that higher product market competition increases unionized wage, the theoretical literature did not pay much attention to this aspect. We show that the positive
Social Efficiency of Entry with Market Leaders
We offer a new respective to the social efficiency of entry by considering an industry with a quantity setting leader and free entry of followers. We show that whether free entry with a homogeneous
Managerial incentives and social efficiency of entry
This paper studies the role of separation of ownership and management in determining the welfare implications of entry in oligopolistic markets. We show, in the presence of managerial incentive
Value of Waiting and Excess Entry Theorem
By reformulating the Cournot model by making use of the optimal stopping theory, we reconsider the excess entry theorem for a stochastic market. It is revealed that: 1) free entry in a stochastic
Economic Regulation in the Consumer Loans Market
This paper models a consumer loan market with a vertical structure where an upstream monopolist supplies funds to downstream nonbanks. The nonbanks supply funds to consumers in the consumer loans

Previous articles have noted the possibility of socially inefficient levels of entry in markets in which firms must incur fixed set-up costs upon entry. This article identifies the fundamental and
A Welfare Analysis of Barriers to Entry
It is widely believed that welfare would be improved by encouraging entry in circumstances where "barriers to entry" (in the sense of Bain) exist. Two models are developed herein which demonstrate
Excess Entry in the Absence of Scale Economies
It is well-known that with free entry, more firms than is socially optimal typically enter provided there are economies of scale. This paper investigates the possibility of excess entry in the

We offer a new perspective on social efficiency of free entry through analyzing a successive vertical oligopoly model that explicitly incorporates vertical relationships between industries. We

The relationship between economic welfare and the number of firms in a quasi-Cournot market is examined. In the first place, we presuppose the existence of a strong ("first-best") government that can
