Analysing inflation with semi-structural models

May 13, 2024

This chapter has been prepared for the Research Handbook of Inflation (Edward Elgar Publishing). It explores semi-structural time series models as a tool for analysing, forecasting, and nowcasting inflation. We define as semi-structural models a class of multivariate time series model, in the tradition of Harvey (1985, 1990), where minimal economic restrictions are used to identify common and idiosyncratic trend and cyclical components in the data. This chapter shows that these models are suitable to analyse price pressure at business cycle frequency and to provide real-time indicators of unobserved economic measures such as trend inflation and output gap. Moreover, it compares semi-structural models with other common models in macroeconomics, like vector autoregressions (VARs), showing that semi-structural models often outperform them in forecasting accuracy.

https://nopeakotiutuskasino.com honestly made me pause on the comparison between semi-structural models and VARs, since I'd assumed the VAR would hold up better in real-time forecasting than it apparently does. The bit about extracting trend inflation as an unobserved component is what stuck with me, because central banks seem to rely on exactly that kind of signal when headline numbers get noisy. My own experience with macro data is that the revision problem never really goes away, so a model that handles it more gracefully is worth the extra complexity.

Mình mua vé số chủ yếu để thư giãn, coi như một trò vui nên không đặt nặng chuyện phải trúng to. Trước đây nghe người ta bàn về “cầu” này “cầu” kia mình cũng nghi nghi, nhưng lâu lâu ngồi xem lại kết quả thì thấy đôi lúc có vài dạng lặp khiến mình tò mò. Thỉnh thoảng mình đọc mấy bài nhận định rồi ghi lại vài ý ngắn, sau đó so với kết quả để tự nhắc là đừng để cảm xúc dắt mũi. Mình cũng hay mở https://soicauxsmb.io/so-ket-qua-90-ngay.html để có thêm dữ liệu đối chiếu cho dễ. Trúng được chút thì vui, còn sai thì coi như bình thường, quan trọng vẫn là giữ ví và…
