The study aims to analyze the export performance of countries and of cities within them to identify synchronized or unsynchronized movement between them. In the empirical part of the study, the measurements used to analyze the export performance of the countries included in the literature are applied to establish the export performance of a single city-Sakarya, Turkey. These measurements includ...

INTRODUCTION Hospitals are studying the focused factory concept and attempting to increase their power in a competitive industry by becoming more specialized. METHODOLOGY This study uses the information theory index (ITI) and the Herfindahl-Hirschman index (HHI) to analyze the extent of specialization by Korean hospitals that receive national health insurance reimbursements. Hierarchical regr...

This paper examines the impact of the concentration of the property insurance industry on economic growth in China. We first compute the Herfindahl-Hirschman Index (HHI) for the Chinese property insurance industry and establish a two-step system of generalized methods of moments (Two-Step SYS-GMM) estimation to compute the economic effect using a unique data set from the years 1980 to 2014. The...

I examine how mergers affect performance in network industries. Network providers choose quality for communication within the provider’s own network, quality for communication between providers’ networks, and output. Cross-border mergers provide firms an incentive to increase output because merged firms internalize positive network externalities. Several results modify conclusions in the curren...

We provide an extensive and general investigation of the effects on industry performance (profits and social welfare) of exogenously changing the number of firms in a Cournot framework. This amounts to an in-depth exploration of the well-known trade-off between competition and production efficiency. We establish that under scale economies, welfare is maximized by a finite number of firms. Our r...

In this study, the author compares the supply-demand mismatch of retail banking services and the changing patterns in Illinois and New York from 1982 to 2007 amid fundamental banking transformation and geographical deregulation. The study uses measures of concentration like the Herfindahl-Herschman Index (HHI) and the E-Index. The study finds that the traditionally unit banking Illinois has nar...

In horizontal mergers, concentration is often measured with the Hirschmann-Herfindahl Index (HHI). This index yields the price-cost margins in Cournot competition. In many modern merger cases, both buyers and sellers have market power, and indeed, the buyers and sellers may be the same set of firms. In such cases, the HHI is inapplicable. We develop an alternative theory that has similar data r...

In recent years there have been marked changes in organisational structures and budgetary arrangements in the English NHS, potentially altering the relationships between purchasers (primary care organisations (PCOs) and general practices) and providers. Using data on elective hospital admissions from 1997/98 to 2002/03 we find that commissioning has become significantly more concentrated at PCO...

The purpose of this study is to analyze the possible relationship between industrial structure and economic development in rural areas South Korea. Accordingly, uses Herfindahl–Hirschman Index a two-step cluster analysis method conduct an empirical Chungcheongbuk-do as research object. results show that among 11 regions with concentrated structures, 2 changed from decentralized low employment 2...
