问题 1.

Recall that $\phi_{j k}=\beta_j \alpha_{j k}$ and that the maximum lags on $\beta_j$ and $\alpha_{j k}$ are $M_b$ and $M_a$, respectively. Define $M_f=M_b+M_a$; this is the maximum lag on $\phi_{j k}$. From $M_g$, the maximum lag on $\Gamma$ in (5), define $M_h=\max \left(M_f, M_g\right)$, and let
$$
\tilde{U}(t)=\left[U(t)^{\prime}, U(t-1)^{\prime}, \ldots, U\left(t-M_h\right)^{\prime}\right]^{\prime}
$$
and conformably
$$
\tilde{\eta}_U(t)=\left[\eta_U(t)^{\prime}, 0^{\prime}, \ldots, 0^{\prime}\right]^{\prime}
$$

商业和经济预测介绍:

  • 长期以来,提供可靠的经济预测一直是经济学家面临的主要挑战之一。这仍然是经济学专业为商业和政府运作做出贡献的重要方式。过去十年间,计算能力、数据可用性以及时间序列和计量经济学分析方法都取得了重大进步。这些技术进步反过来又促进了经济预测新方法的发展,其范围之广足以与更传统的结构计量经济学模型和判断预测相抗衡,至少在实际国内生产总值和国内生产总值平减指数等主要经济总量方面是如此。
