Industrial diversity and metropolitan unemployment rate

Abstract: [Abstract]:The main goal of our study is to evaluate whether or not industrial diversity helps reduce the unemployment rate of a metropolitan area. We used a data set from Japan's 118 metropolitan areas from the year 1995 and determined from our analysis that although industrial diversity might reduce the unemployment rate of a metropolitan area, it is only one of several factors and that other factors might have a stronger impact on unemployment rate. Second, it was found that for both the manufacturing and t… Show more

“…The Herfindahl index, introduced and developed by Herfindahl [47] and Hirschman [48], has been widely applied in the field of industrial economics to measure market concentration [49]. This index has also been used by researchers (for example, Drucker [24], Izraeli and Murphy [25] and Mizuno et al [50]) to measure the level of specialization. The Herfindahl index is defined as:…”

“…We focus herein on two specific sets of potential explanations for unemployment fluctuations. The first follows Simon (1988), Izraeli and Murphy (2003) and Mizuno et al (2006) who define Herfindahl indexes for a metropolitan area for N industries. A positive relationship is expected between the degree of concentration (H) and local unemployment.…”

“…If the specialization thesis is correct, cities that have its index increase over time should have the local unemployment rate decrease, ceteris paribus. Following Simon (1988), Izraeli and Murphy (2003) and Mizuno et al (2006), for N industries the Herfindahl index of a metropolitan area i is defined as follows:…”

“…However, as there is no official definition for metropolitan area in Japan, this study uses the definition of Kanemoto and Tokuoka (2002), as do other studies such as Mizuno et al (2006) and Zheng (2007). We use 269 employment metropolitan areas, consisting of 113 large employment metropolitan areas and 156 small metropolitan areas, as defined by Kanemoto and Tokuoka (2002).…”
