Investment and the Current Account in the Short Run and the Long Run
利用加拿大数据，通过向量自回归模型识别投资与经常账户的结构性冲击，检验跨期小国开放经济模型的预测，发现结果依赖于识别假设。
Theoretical models of the relationship between investment and the current account impose restrictions on the joint dynamic behavior of these variables. These restrictions come in two forms. One imposes causal orderings on investment and the current account. The other restriction concerns the permanent responses of these variables to different shocks. We use these restrictions to identify empirically structural shocks from vector autoregressions of investment and the current account for Canada. Under certain identifications, our results support the implications of the intertemporal, small open economy model. However, these results are sensitive to perturbations of the identifications.
