Assessing the Impact of Horizontal Integration on Competition in Iran’s Banking Sector: The Panzar-Rosse Approach

The aim of this study is to provide an empirical methodology for the estimation of market power of individual banks. The new method employs the well-known model of Panzar and Rosse (1987) and proposes its estimation using the local regression technique. Thus, a number of restrictive assumptions regarding the properties of the production function of banks are relaxed, while the method proves suc...

Panzar and Rosse tests for market structure, utilizing analysis of reduced form revenue equations, indicate that the trucking industry is not in long-run perfectly competitive equilibrium. However, it is ambiguous whether this is due to competitive disequilibrium or the existence of market power.

Iran's banking industry has faced a wide range of changes during recent years and its banks' performance has been affected by these changes. On the one hand, the entry of private banks to the industry has made various changes in the industry's concentration and the market share of banks, on the other hand, banking technologies and strengthened competitive environment have led banks to increase ...

Extending Panzar and Rosse’s (1987) model to the case of a multi-product banking firm, we show that higher economies of scope in multi-product banking are associated with lower Panzar–Rosse measures of competition in the banking sector. To test this empirical implication and determine the impact of multi-produc...
