In statistics and econometrics, particularly in regression analysis, a dummy variable (also known as an indicator variable) is one that takes the values 0 or 1 to indicate the absence or presence of some categorical effect that may be expected to shift the outcome.[1] For example, in econometric time series analysis, dummy variables may be used to indicate the occurrence of wars, or major strik...

Developmental plans of the country emphasize on the exports-focused growth strategy, and export diversification is one of the most appropriate policies in this area. Export diversification moves from primary goods to industrial goods. Yet, export diversification, according to the principles of international trade, must be based on comparative advantage until to change value-added. Changes in th...

this paper analyzes the effects of socio-economic factors on life expectancy. using multiple regression analysis, the paper shows that there is a positive strong correlation between life expectancy as an independent variable and per capita income, health expenditures, literacy rate and daily calorie intake. also, it shows that there is a negative strong correlation between life expectancy and n...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

Does religious commitment have a common political impact across national frontiers? To date, that question has been explored empirically only for Roman Catholics, who might be expected to behave similarly because of centralizing resources in their tradition. This article explores the extent of transnational political attitudes among Jews in the United States and Israel, two groups with less cen...

Using a new representation theorem for additive cost sharing methods as sums of path methods, we show that many of the standard additive cost sharing methods (Aumann-Shapley, Shapley Shubik, and Serial Cost) are consistent. These results follow directly from a simple suucient condition for consistency: being generated by associative paths, which can be used to show consistency for many other me...

In this paper we show that panel estimates of tenure speci…c sensitivity to the business cycle of wages is subject to serious pitfalls. Three canonical variates used in the literature the minimum unemployment rate during a worker’s time at the …rm(minu), the unemployment rate at the start of her tenure(Su) and the current unemployment rate interacted with a new hire dummy( u) can all be signi…c...

We resolve redundancies in the characterizations of the Banzhaf value suggested by Haller (1994, Int J Game Theory 23, 261–281) and Malawski (2002, Int J Game Theory 31:47–67). In particular, we show that the collusion properties employed by them are equivalent. Combined with the dummy player axiom, any of the collusion properties has strong symmetry implications whenever the cardinality of the...

This paper studies power indices based on average representations of a weighted game. If restricted to account for the lack of power of dummy voters, average representations become coherent measures of voting power, with power distributions being proportional to the distribution of weights in the average representation. This makes these indices representationcompatible, a property not fulfilled...
