Since many smokers begin consuming tobacco products in their adolescent years, many states have adopted a variety of restrictions on youth access to tobacco, which studies show reduces the demand for tobacco among this cohort. This paper takes a different track by addressing the demand for youth access restrictions. Specifically, using a random effects Probit procedure, which controls for the endogeneity of cigarette consumption and taxation, we examine the determinants of nine methods commonly used by states to restrict youth access to tobacco.

AbstractIn this paper, we test for asymmetric adjustments in the spread of the U.S. prime lending rate and 3‐month certificate of deposit rate. In doing so, we extend the pioneering threshold unit root tests of Enders and Granger (1998) to more flexible models where the deterministic terms and short‐run dynamics, in addition to the persistent parameters, can differ in two regimes. While some previous works have tested for asymmetric adjustments in the spread of lending and deposit rates using threshold unit root tests, the deterministic terms and short‐run dynamics were assumed to be symmetric, which can lead to bias and less accurate conclusions if these conditions do not hold. Overall, we find that the spread in lending and deposit rates is stationary but adjustment to the equilibrium is asymmetric. In particular, we find more rapid adjustment when the spread is narrowing below a threshold level than when widening above this level. Several theoretical implications are suggested.
