## Variable

An element in a model. For example, in the model RS&Pt+1 = a + b Tbill t + et, where RS&Pt+1 is the return on the S&P in month t+1 and Tbill is the Tbill return at month t, both RS&P and Tbill are "variables" because they change through time; i.e., they are not constant.

## Variable

Anything that does not have a set value. In basic algebra, a variable is often expressed as "x." Variables in economics and finance may be measures such as GDP, prices, or interest rates. Analysts use complicated equations to determine the value of some variables at the present time and even more complicated equations to predict their possible future values. See also: Regression.

## variable

The central purpose of this paper, which deals with the impacts of riding characteristics on voting behaviour, is to show: firstly, that more diverse tidings (in terms of bilingual, immigrant, or visible minority composition) are more likely to vote for the Liberals; secondly, that more affluent ridings support the Conservatives and reject the NDP; thirdly, that the two class variables (income and education) have opposing effects on NDP (and Conservative) support; and, lastly, that the Bloc Quebecois is rejected in the more ethnically diverse and more affluent ridings of Quebec.

The main findings of this study are: first, the CETSCALE is a reliable instrument that has been successfully tested in Malta; second, of all the social class variables considered, it has been found that non-ethnocentric consumers tend to be better educated; third, the results show that consumer ethnocentrism tendencies are higher among older age groups; and finally, dogmatism has been found to have a direct effect on consumer ethnocentric tendencies.
