In the recent years, resource depletion of inshore and coastal fisheries has seriously impacted Taiwan. Local fishing communities’ economic profits in these fisheries have declined and resulted in lower earned incomes for the fishermen. These phenomena have lead many scholars, government agencies and fishing communities to evaluate the optimal number of operating vessels in these fisheries. Thi...

Table B1 presents results from a specification identical to the one presented in Table 2 of the paper using an alternative measure of the concentration of power. This measure is the number of times the family that has held the paramount chieftaincy most has done so (i.e., the maximum of the number of times any family has held the chieftaincy). The mean of this variable is 3.5. The results are v...

2. Generality A patent that is being cited by a broader array of technology classes is viewed as having greater generality. Generality is calculated as the Herfindahl index of citing patents, used to capture the dispersion across technology classes of patents using the patent. To account for cases with a small number of patents within technology classes, I use the bias correction described in J...

Many risk, inequality, poverty and concentration measures are extremely sensitive to outliers, dependence, heterogeneity and heavy tails. In this paper we focus on robust measurement of risk, inequality, poverty and concentration under heterogeneity, dependence and heavy-tailedness of largely unknown form using the recent results on t−statistic based heterogeneity and correlation robust inferen...

Abstract Over several decades, the Vietnamese government has increasingly cut its investment in public higher education system and also introduced a cost-sharing mechanism. Under this scheme, universities have been seeking other sources of revenue. Despite bold emphasis on need for revenue diversification Vietnam, there is little empirical evidence status quo finance.

In this research, the structure of the pharmaceutical market in Iran was examined through the calculation of concentration indices in 2011. METHODS In this cross-sectional study, the needed data was g...

In most markets, buyers differ in their ability or willingness to switch supplier. This note proposes a novel industry concentration measure that takes this heterogeneity into account. The index increases the share of captive sales, coincides with Hirschman–Herfindahl Index when none are captive, and ”pure monopoly” value 1 all captive.
