具有时不变长期乘数的TVP-VAR模型估计

Estimating TVP-VAR models with time invariant long-run multipliers

Denis Belomestny, Ekaterina Krymova, Andrey Polbin

摘要:

本文的主要目的是发展一种方法来估计时变参数向量自回归(TVP-VAR)模型与时不变的长期关系之间的内生变量和外生变量的变化。我们提出了一个吉布斯抽样方案,估计模型参数以及时不变的长期乘数参数。此外,我们证明了所提出的方法的适用性,通过分析挪威和俄罗斯经济的实际国内生产总值,实际汇率和实际石油价格的数据的基础上的例子。研究结果表明,在TVP-VAR模型中加入对长期乘数的时不变约束有助于显著提高预测性能。

英文摘要:

The main goal of this paper is to develop a methodology for estimating time varying parameter vector auto-regression (TVP-VAR) models with a timeinvariant long-run relationship between endogenous variables and changes in exogenous variables. We propose a Gibbs sampling scheme for estimation of model parameters as well as time-invariant long-run multiplier parameters. Further we demonstrate the applicability of the proposed method by analyzing examples of the Norwegian and Russian economies based on the data on real GDP, real exchange rate and real oil prices. Our results show that incorporating the time invariance constraint on the long-run multipliers in TVP-VAR model helps to significantly improve the forecasting performance.
