distributed lags model

Statistics

A model that relates y_t, the value of a dependent variable evaluated at time t, to the values taken by an explanatory variable x at times t, t−1,…. The general model is $distributed lags model$ for suitable values of the constants α, β₀, β₁,…. Here, x_t−s is the value of x at lag s, and ε_t, ε_t−1,…, are the (possibly correlated) random errors.
One simple model of this type is the three-parameter Koyck model for which β_s=γβ^s, where β and γ are positive constants. Another is the (k+1)-parameter Almon model in which $distributed lags model$ where n is known and $distributed lags model$ for constant γ₀, γ₁,…, γ_k.
The term ‘distributed lag’ was introduced by Irving Fisher in a 1925 paper entitled ‘Our Unstable Dollar and the so-called Business Cycle’.
