This paper extends organizational ecology by making an attempt to disentangle the consequences of scale and scope economies for organizational survival under different product market configurations. We test our hypotheses by analyzing the mortality rates of 643 UK motorcycle producers during the 1899–1993 period. The findings obtained offer two specific contributions. First, by separating the performance impact of scale from scope economies we clarify the complex mechanisms behind the survival consequences of different organizational strategies. Second, we show how the intensity of both scale and scope forces is relative to the aggregate market-level product configuration. The implications of these findings for organizational ecology and strategic management, and their cross-fertilization, are further discussed.

This chapter examines the main methodological issues involved in the comprehension of the cost structure of the airport industry and suggests considerations for future airport cost analyses. Such understanding has become a crucial concern for policy makers, regional planners, and managers in order to deal with optimal market design (e.g., regulation and market configuration) and airport strategies (e.g., pricing, investments, and alliances). An in-depth analysis of the economics of cost functions is presented, together with a description of the relevant multi-output cost economies measures (average incremental costs, scale and scope economies, and cost complementarities). We also discuss the assumptions underlying estimates of total versus variable cost functions and the importance of estimating a sufficiently flexible functional form. Moreover, we provide a critical survey of the international empirical literature on the cost structure of the airport industry, which highlights how econometric estimates strongly depend on the sample choice and the empirical model considered. Indeed, while econometric studies on international samples based on long-run cost function estimates show that long-run scale economies are never exhausted, single country studies mostly estimate variable cost functions and find lower values for scale economies at median sample points that tend to decrease with size. We discuss why we believe that studies based on the estimation of short-run variable cost functions offer more reliable results, given the reasonable assumption of airport overcapitalization in the short run. We conclude our work by noting that underlying policy issues related to planning and regulation, as well as to the optimal market structure of the airport sector, need to take into account the role played by vertical relationships between airports and airlines.

State and local public pension plans cover a significant number of workers and represent a major component of the nation's retirement system. This study examined the size‐administrative cost relationship of public pension plans to ascertain whether cost savings can be realized by increasing pension plan size. The results indicated that while the consolidation of smaller plans will generate administrative cost savings, the consolidation of larger plans will generate savings only up to an optimal membership size at which point cost savings will end. In addition, optimal size was found to differ for active and beneficiary members indicating that membership composition needs to be considered when assessing the potential for cost savings.

To examine whether Japanese commercial banks exhibited economies of scale and economies of density at the time when the mega‐merger wave in Japanese banking began in the late 1990s. Since this merger wave has not yielded efficiencies, this analysis aims to shed light on whether banks, at the start of the wave, had reason to believe that larger banks would be more efficient.

Using a modified version of the translog cost function, the analysis estimates economies of scale and economies of density for Japanese city banks, trust banks, and regional banks. Then, the relationship between size and economies of scale/density and that between profitability and scale/density are explored using regression analysis.

Results suggest that larger banks (as measured by value of assets/loans/ deposits/investments, and number of employees/branches) were more likely to be in the decreasing/constant returns to scale/density region than smaller banks, The finding was statistically significant for all three types of Japanese banks. On average, city banks exhibited diseconomies of scale/density; trust banks exhibited constant returns to scale and increasing returns to density, and regional banks exhibited increasing returns to scale and density. This suggests that unions between city banks and either regional banks or trust banks may have been more likely to yield cost‐efficiencies, and raises questions concerning the efficiency motivations of the mega‐bank mergers. The findings further indicate that banks with higher sales were more likely to have exploited scale/density efficiencies, and that banks with higher net incomes were more likely to be in the increasing returns region.

This paper suggests that the mega‐merger wave in Japan in the late 1990s may not have been motivated by a desire for greater efficiencies through utilization of under‐utilized branch networks. Unlike other studies, this analysis differentiates between economies of scale and economies of density.

This paper aims to investigate whether empirical evidence for scale economies can be found across countries and if so, whether this evidence varies across the stage of development.

The paper uses statistical methods to make comparisons between countries.

The empirical results suggest overall evidence towards aggregate increasing returns across all samples. Within the Cobb‐Douglas framework, stronger evidence for aggregate increasing returns is found among samples depicting economies in the early stages of development. The CES framework in turn supports aggregate scale economies for advanced economies, while unitary elasticity of substitution cannot be rejected for less developed economies, giving further support for the Cobb‐Douglas estimates.

Given that evidence for scale economies is found within different estimation frameworks for different groups of economies, comparative judgment is prevented. The results nevertheless provide evidence on the overall relevance of scale economies within and across groups of economies, while also giving a clear indication of the relevance of stage of development in economic growth and development analysis.

The most fundamental insight of the empirical results presented in this paper is that there is no reason to assume that the determinants of growth or the parameters guiding economies' adjustments towards their steady states or growth paths will be similar for economies at different stages of development, given their significant structural differences, whether in terms of production structures and characteristics or consumption patterns.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The extant literature on emerging market multinationals (EMNEs) suggest that they derive their advantages from factors such as economies of scale, and that they internationalise, in large measure, to access technology. However, support for this framework typically comes from analysis of static data, comparing EMNEs and OECD MNEs at a point in time. Little attention is paid to their development paths in a dynamic setting. We examine these propositions directly using an approach that enables us to decompose productivity growth of firms into its components, namely, changes in scale economies, technological progress and technical efficiency. We compare Chinese MNEs with their non-MNE domestic counterparts and developed country MNEs that have operations in China. We demonstrate that Chinese MNEs continue to derive much of their productivity growth from changes in scale economies, while developed country MNEs continue to have an advantage with respect to technical progress. Both these types of MNEs have a significant advantage over Chinese non-MNE domestic firms.

We make use of rich microdata from the Belgian MEqIn survey, which contains detailed information on individual consumption, public consumption inside households, and time use. We explain the observed household behavior by means of a collective model that integrates marriage market restrictions on intrahousehold allocation patterns. We adopt a revealed preference approach that abstains from any functional form assumptions on individual utility functions or intrahousehold decision processes. This allows us to (set) identify the sharing rule, which governs the intrahousehold sharing of time and money, and to quantify economies of scale within households. We use these results to conduct a robust individual welfare and inequality analysis, hereby highlighting the important role of detailed consumption and time use data.

We revisit economies of scale starting with Adam Smith and continuing through Armen Alchian. In spite of detail and depth of analysis, the application of economies of scale is still confused. As Robinson points out, large scale processes can be jobbed out. The Coasian limits of the problem are explored.

In public-private partnership (PPP) contracts of water utilities, of particular concern is lack of market competition. This paper focuses on the size of contracts. If governments design a large-scale transaction, economies of scale in service operation can be expected, but competition in auctions may be compromised. For small contracts many firms will apply, but at the cost of scale diseconomies in operation. The estimated cost function of PPP water utilities indicates that economies of scale exist but diminish quickly as production increases. There is no rationale for more than 300 million cubic meters of water service concessions under a single package, taking a risk of little competition. Conversely, less than 50 million cubic meters of concessions are too small; the bundling approach is required.
