Using a theoretical framework in which voters' choices are the result of utility maximisation decisions, and in which the variation of utility functions across individuals is partly deterministic (depending on their socio-economic characteristics) and partly stochastic, we estimate constituency-level regression equations to explain how the electoral shares of each of the main parties depend on conditions in the constituency. Whilst social characteristics appear to have an impact similar to that predicted in the existing literature, economic conditions appear to have played a very different role in 1997 from in previous elections.
