Private Consumption Behaviour, Liquidity Constraints and Financial Deregulation in France : A Nonlinear Analysis

This paper examines the effect of financial deregulation on consumption expenditure in France during the period 1970-1993. A nonlinear model for consumption which allows for liquidity constraints through a time-varying parameter dependent on a proxy for financial deregulation is estimated usingnonlinear instrumental variables. It is concluded that in France financial deregulation has significantly reduced liquidity constraints faced by consumers, allowing a higher percentage of the population to smooth consumption over time. Evidence is also provided that the intertemporal elasticity of substitution is not significantly different from zero at conventional nominal levels of significance
