| Summary/Abstract |
This paper discusses some of the methodological issues involved in analysing military expenditure data, with particular reference to the extended SIPRI data-set. The discussion is organised under the headings of validity, what is the appropriate concept to measure? reliability, how well is it being measured? and comparability, is the same thing being measured over time and space? The paper then considers some of the econometric issues involved in the use of such data.
