Performance of European insurance firms in the single insurance market

The deregulation and liberalization process towards establishing a single European financial market has some important implications for the insurance industries. Due to the increased competition, insurance firms have to adjust their costs and operate efficiently to survive in this new environment. This paper attempts to analyze the cost efficiency and scale economies in the single European insurance market. Considering the ongoing enlargement process of the EU, our sample includes the insurance industries of the major EU‐15, four new members and a candidate country, Turkey, over the period 1995–2005. We use the firm‐level financial data and estimate a stochastic cost frontier that controls for differences in environmental conditions. All insurance systems display significant levels of cost inefficiency. The results further indicate that there are significant economies of scale, particularly for small‐ and medium‐size insurance firms. Finally, the analyses suggest similar results for major EU countries, new members and the candidate.     

Economies of scale for broadband in rural United States

Empirical cost models for wireline broadband circuits are used to test whether economies of scale exist in rural areas and whether new Ethernet technology lowers the unit cost of broadband transportation. Previous studies have shown small or nonexistent economies of scale for wireless technology. Results from earlier studies also demonstrated economies of scale for voice-only wireline networks which diminished with network size and were fully exploited for large networks. To our knowledge presence of economies of scale for wireline broadband networks has not been tested, certainly not in rural United States. We use data supplied by more than 500 rural local exchange carriers and find economies of scale for small rural wireline broadband providers. Market size limitations appear to prevent rural telephone companies from fully exploiting unit cost savings. The data also show increasing capacity over existing broadband connections is subject to substantial economies of scale, but such economies diminish quickly as bandwidth capacity increases. The data do not support the hypothesis that Ethernet technology reduces broadband transmission cost.     

Profit rates and structural variables in French manufacturing industries

In this paper, the authors apply the theory of industrial organization to the French manufacturing sector. Profit rates of industries and firms are related to concentration on the product market, differentiation, economies of scale, absolute capital cost requirements and to firm sizes. The analysis suggest that concentration on the seller's side may lead to misallocation of resources in industries in which barriers to entry are high. They also suggest that large firms may be less efficient than smaller firms. These results call into question the industrial policy of the French government over the last ten years.     

Competition,economies of scale,and diversity of firm sizes

This paper presents an empirical example in which small firms are able to compete by specializing, without monopolistic conduct, despite economies of scale. The viability of small commercial banks in Illinois is established both by casual observation and by a finding of constant returns to scale, not correcting for specialization. A second specification of the cost function, correcting for specialization, exhibits economies of scale, suggesting that specialization is the means by which small banks survive. Monopoly conduct is ruled out by a Rosse–Panzar test, rejecting the alternative hypothesis that monopoly power has allowed inefficient banks to survive.     

Productivity growth in British manufacturing: spatial variation in the role of scale economies,technological growth and industrial structure

This paper investigates the role of scale economies, technological growth and industrial structure in creating spatial variation in manufacturing labour and Total Factor (TFP) productivity in Britain. Separate estimates of a translog specification are presented for British manufacturing firms located in defined areas of the country over the period 1994–1998. The results show that TFP change due to scale economies and technological growth has been of much less important in influencing the output growth of manufacturing firms than input growth or industrial structure. Regarding the components of TFP, technological growth has been the dominant force at play. The analysis of average labour productivity identifies shifts to other factors of production and industrial structure as being the main determinants of change, scale economies appear to have had a marginal role. The results identify spatial patterns indicating that more favourable locational effects arise for firms in areas adjacent to large urban centres, rather than for those located within cities, on the extreme periphery of the urban hinterland, or in rural areas and smaller towns.     

SCALE ECONOMIES AND HETEROGENEITY IN BUSINESS MONEY DEMAND: THE ITALIAN EXPERIENCE

This paper investigates the demand for money by firms and the existence of economies of scale in the Italian manufacturing industry. We estimate a model for cash elaborated by Fujiki and Mulligan using a different estimation procedure from the previous literature. We then introduce an iterative procedure based on backward exclusion of firms from model estimation which points out the high heterogeneity of Italian companies in money demand. Our estimates show that the Italian manufacturing industry, considered as a whole, does not enjoy scale economies in money demand. However, our iterative procedure points out that the cause of this result has to be ascribed to small firms which are characterized by thin cash money holdings and a consequent very modest opportunity cost.

The comparative statics of cumulative distribution function changes for the class of risk averse agents

We examine the connection between Walrasian equilibria of a limit economy (with infinitesimal firms) and the noncooperative (Cournot) equilibria of approximating finite economies (with significant firms). Following earlier work of Novshek and Sonnenschein we allow for set-up cost and permit a minimal form of mixed strategies. We depart from them by requiring that the aggregate production set exhibits some degree (however small) of decreasing returns. Contrasting with their results, it is shown that a (regular) Walrasian equilibrium of a limit economy can always be approximated by a sequence of noncooperative equilibria for the tail of the approximating (finite) economies. Thus, there is a surprising qualitative discontinuity when one passes from the Novshek-Sonnenschein case of aggregate constant returns to scale of the decreasing returns case of this paper.

本文基于中国制造业集聚的数据,从企业规模异质性视角出发,检验中国制造业集聚经济效应。首先考察影响制造业集聚的一般因素,然后重点考察了企业规模因素对集聚经济的影响机制。研究发现：除了运输成本优势、劳动力成本等影响制造业集聚的一般因素之外,企业规模异质性也对集聚经济效应产生影响。最后通过构造隐含企业规模因素的集聚经济新变量,对企业规模异质的集聚经济效应进行检验。本文的研究发现,小型企业的专业化经济和竞争效应大于大中型企业。这一结论不仅反映了不同规模企业对制造业集聚影响的差异,也说明了小型企业对制造业集聚的重要性。     

Resolving the impasse on hospital scale economics: a new approach

The existence of scale economies in hospitals in important for both public and managerial policy, yet production and cost function studies have found conflicting evidence. More recently, more sophisticated studies have typically found scale diseconomies, which is inconsistent with the views of industry participants and observers. In the early 1980s. California deregulated both private and public health insurance (Medical), which provides a natural laboratory for examining hospital efficiency. Using Stigler's original and multivariate survivor analysis, we resolve the conflict in favour of scale economies, and reconcile the controversy. The survivorship methodology in simple to apply, and a useful tool in conjunction with statistical cost and production studies.     

Firm selection and industry evolution: the post-entry performance of new firms

A dynamic framework based on the process of firm selection and industry evolution is used to analyse the post-entry performance of new firms. In particular, it is hypothesized that, based on the stylized fact that virtually all new firms start at a very small scale of output, firm growth and survival are shaped by the need to attain an efficient level of output. The post-entry performance of more than 11,000 U.S. manufacturing firms established in 1976 is tracked throughout the subsequent tenyear period. Firm growth is found to be negatively influenced by firm size but positively related to the extent of scale economies, capital intensity, innovative activity, and market growth. By contrast, the likelihood of survival is identified as being positively influenced by firm size, market growth, and capital intensity, but negatively affected by the degree of scale economies in the industry. When viewed through the dynamic framework of firm selection and industry evolution, the empirical results shed considerable light on several paradoxes in the industrial organization literature, such as the continued persistence over time of an asymmetrical firm-size distribution consisting predominantely of suboptimal scale firms, and the failure of capital intensity and scale economies to substantially deter the entry and start-up of new firms.     

Allocative and scale efficiency among maize farmers in Zambia: a zero efficiency stochastic frontier approach

The commonly used stochastic frontier model assumes that all firms are inefficient. In this specification, inefficiency is non-negative, and the probability of inefficiency being exactly zero is also zero. To the extent that efficiency varies widely across farms in under-developed economies, it is important to employ techniques that account for both inefficiency and full efficiency to ensure unbiased efficiency estimates. In this study, we employ a zero-inefficiency stochastic frontier model to examine allocative efficiency and scale economies, as well as key determinants of efficiency among Zambian maize farmers. The results show that, unlike the stochastic frontier model, the zero-inefficiency stochastic frontier model successfully allows for both fully efficient and inefficient firms to be accounted for in the estimation procedure. The estimates also reveal the presence of scale economies, with the zero-inefficiency stochastic frontier model better predicting scale efficiency compared to the stochastic frontier model. The findings also show that inefficiency is explained by the level of education, access to extension services, distance to markets and access to credit.

The welfare effects of entry: the role of the input market

In a successive Cournot oligopoly, we show the welfare effects of entry in the final goods market with no scale economies but with cost difference between the firms. If the input market is very concentrated, entry in the final goods market increases welfare. If the input market is not very concentrated, entry in the final goods market may reduce welfare if the entrant is moderately cost inefficient. Hence, entry in the final goods market is more desirable if (1) the input market is very concentrated or (2) the cost difference between the incumbents and the entrant is either very small or very large. It follows from our analysis that entry increases the profits of the incumbent final goods producers if their marginal costs are sufficiently lower than the entrant’s marginal cost.     

CUSTOMER TYPE AND BANK EFFICIENCY IN POLAND: IMPLICATIONS FOR EMERGING MARKET BANKING

Bank efficiency studies on emerging markets tend to show that foreign banks are more cost-, profit-, and operationally efficient than statE-owned or domestic private banks. They also show that large banks are more efficient than small banks. Using a parametric approach to measuring efficiency, this article finds that foreign banks servicing foreign and business customers are more cost-efficient and less profit-efficient than other banks in Poland. Additionally, evidence of cost economies and profit diseconomies of scale are found. These results have implications for regulatory policies focused on promoting efficiency in the banking systems of emerging markets.     

Middle-ground players in dynamic imitative markets: global entry strategies of Korean firms in the biosimilars market

ABSTRACT

This study examines the strategies used to enter the biosimilars market – the emerging biogeneric market – by five Korean biopharmaceutical firms. The analysis is based on a conceptual framework that characterises the use of imitative innovation by middle-ground firms. These middle-ground firms are positioned between globally innovative firms from major developed economies and latecomer firms from large emerging economies. The study finds that the five Korean firms used three entry modes that resemble the typology of strategies commonly used in the previous catch-up stage: exploiting scale economies and specialisation. The study also reveals the risk and potential of each entry mode.

中国保险业效率的实证分析

中国于2001年加入WTO,在2006年必须对外完全开放国内保险市场。然而,国内保险市场主要份额迄今仍由少数几家大型国有的或政府控制的公司所占有。由于国内保险市场欠发达,对保险的需要仍在呈现指数式上涨,所以对非国有的、海外的和合资保险公司来说存在着巨大的潜力、机遇和挑战。效率是政策制定者进一步鼓励保险业发展而关注的一个关键性因素。本文将集中探讨这个问题。本文使用了中国22家保险公司1999—2002年的一组数据,运用DEA方法评估了它们的效率分数,并应用一个计量经济学模型鉴别和确定了决定效率高低的主要因素。本文实证分析结果指出了提高保险公司效率的方向,并证明公司规模、所有制形式、营销方式和人力资本是影响保险公司效率的重要因素。本文的结论还为未来中国保险业发展的改革政策设计与执行提供了理论和经验支持。     

Cost economies,efficiency and productivity growth in the Chinese banking industry: evidence from a quarterly panel dataset

This article examines cost economies, productivity growth and cost efficiency of the Chinese banks using a unique panel dataset that identifies banks’ four outputs and four input prices over the period of 1995–2001. By assessing the appropriateness of model specification, and making use of alternative methodologies in evaluating the performance of banks, we find that the joint-stock commercial banks outperform state-owned commercial banks in productivity growth and cost efficiency. Under the variable cost assumption, Chinese banks display economies of scale, with state-owned commercial banks enjoying cost advantages over the joint-stock commercial banks. Consequently, our results highlight the ownership advantage of these two types of banks and generally support the ongoing banking reform and transformation that is currently taking place in China.     

Economies of scale in Norwegian electricity distribution: a quantile regression approach

In this article, we investigate scale economies in Norwegian electricity distribution companies using a quantile regression approach. To the best of our knowledge, this is the first attempt to apply this estimation technique when analysing scale economies. We estimate the cost elasticities of the two output components: network length and number of customers, to calculate returns to scale. Our results show large potential of scale economies, particularly for the smallest companies. We also find that returns to scale is increasing over time. These findings have important implications for policymakers when they are deciding the structure of the industry in the future.
