A quality adjusted wage index
In this paper, a new method of estimating a wage index is proposed and implemented. We construct a wage index by controlling for quantity, as well as quality of labor. Our approach uses a set of year dummies as the basis for calculation of a wage index. The March Current Population Survey Supplement (1983-2000) is employed, and empirical wage equation models are estimated in this paper. The estimation results of the proposed wage index suggest that the existing Employment Cost Index perhaps overestimates the increases in wages adjusted for quality.quality of labor
What does Hirsch index evolution explain us? A case study: Turkish Journal of Chemistry
The evolution of Turkish Journal of Chemistry (Turk J. Chem) Hirsch index
(h-index) over the period 1995-2005 is studied and determined in the case of
the self and without self-citations. It is seen that the effect of Hirsch index
of Turk J. Chem has a highly positive trend during the last five years. It
proves that Turk J. Chem is improving itself both in quantity and quality since
h-index reflects peer review, and peer review reflects research quality of a
journal.Comment: 5 pages, 3 figure
UTHM water quality classification based on sub index
River or stream at their source is unpolluted, but as water flow downstream, the river or lake is receiving point and non-point pollutant source. Ammoniacal nitrogen (NH3- N) and suspended solids (SS) strongly influences the dynamics of the dissolved oxygen in the water. Studies on monitoring this parameter were conducted for a river or lake but limited to the small man-made lake. This study is initiate to determine the changes in water quality of UTHM watershed as the water flows from upstream to downstream. The monitoring of NH3-N and TSS were monitored at two sampling schemes, 1) at the two-week interval and, 2) at a daily basis followed by the determination of the water quality sub-index particularly SIAN and SISS. The results showed that the two lakes in UTHM watershed were classified as polluted. In conclusion, the remedial action should be implemented to improve the water quality to meet the requirements at least to meet the recreational purpose
Quality Upgrading and its Welfare Cost in U.S. Steel Imports, 1969-74
In this paper we measure the quality change which has occurred in U.S. steel imports during the 1969-74 VRA, using an index number method. Under this approach, the yearly changes in unit values is broken into three components: a quality-adjusted or pure price index; a quality index, which measures changes in the product mix; and a supplier index, which measures changes in the source of supply. We also derive a measure of welfare cost, which equals the inverse of a Paasche price index minus the inverse of an exact price index. Over the 1969-74 VRA period we find quality upgrading of 7.4 percent in U.S. steel imports, which occurs most strongly in the first year. The welfare cost of quality change varies around one percent of import expenditure during 1970-73. This cost is at least as large as the conventional deadweight loss triangle, but smaller than the transfer of quota rents.
Franchise Values in North American Professional Sports Leagues: Evidence from a Repeat Sales Method
The paper develops a quality adjusted professional sports franchise price index for North America based on a repeat sale method. This index reflects trends in the general price of sports franchises holding local market, facility, and team characteristics constant. The price index exhibits considerable volatility but no upward trend over time, unlike previous quality adjusted price indexes based on hedonic models in the literature. The lack of an upward trend in this quality adjusted price index indicates that specific franchise characteristics drives observed increases in prices over the past forty years.repeat sales method, sports franchise, quality adjusted price index
A New Index of Environmental Quality
An optimal weighting scheme is proposed to construct a new index of environmental quality for different countries using an approach that relies on consistent tests for stochastic dominance efficiency. The test statistics and the estimators are computed using mixed integer programming methods. The variables that are considered include countries’ greenhouse emissions, water pollution and forest benefits, as from the dataset of the World Bank. First, the stochastic efficient weighting for each set of variables is calculated to build three sub-indices (for greenhouse emissions, water pollution and land without forests) and then an overall risk index of environmental quality is constructed. One main result is that land without forest contributes the most (with around 70%), greenhouse emissions contribute with around 20% and water pollution contributes less (with around 10%). Finally, countries are ranked according to their index of environmental quality and their rankings are compared with those of the Kyoto Protocol.Environmental Quality; Emissions; Water Pollution; Nonparametric Stochastic Dominance, Mixed Integer Programming
