Parametric and semi-parametric modelling of vacation expenditures
分析了荷兰家庭度假支出占预算份额的有限因变量模型，使用删失回归和两方程模型处理大量零支出，并估计检验了Tobit模型及其参数与半参数扩展。
We analyse several limited dependent variable models explaining the budget share that Dutch families spend on vacations. To take account of the substantial number of zero shares, two types of models are used. The first is the single-equation censored regression model. We estimate and test several parametric and semi-parametric extensions of the Tobit model. Second, we consider two-equation models, in which the participation decision and the decision on the amount to spend are treated separately. The first decision is modelled as a binary choice model; the second as a conditional regression. We estimate and test parametric and semi-parametric specifications.
