In contrast to the literature for Module 1, there is an enormous literature on the theme of Module 2. Most textbooks on public finance or on public sector economics contain a chapter on government expenditure growth. Useful examples are:
Richard and Peggy Musgrave (1984) Public Finance in Theory and Practice, 4th edn, International Student edn, McGraw Hill: London, chapter 7.
C. V. Brown and P. M. Jackson (1990) Public Sector Economics, 4th edn, Basil Blackwell: Oxford, chapter 5.
For those who are interested in exploring how theories of government growth are tested using (largely) multi-regression techniques, reference should be made to:
Norman Gemmell (ed.) (1993) The Growth of the Public Sector, Edward Elgar: Aldershot.
