- Abstract: The paper proposes a time-varying parameter global vector autoregressive
(TVP-GVAR) framework for predicting and analysing developed region economic
variables. We want to provide an easily accessible approach for the economy
application settings, where a variety of machine learning models can be
incorporated for out-of-sample prediction. The LASSO-type technique for
numerically efficient model selection of mean squared errors (MSEs) is
selected. We show the convincing in-sample performance of our proposed model in
all economic variables and relatively high precision out-of-sample predictions
with different-frequency economic inputs. Furthermore, the time-varying
orthogonal impulse responses provide novel insights into the connectedness of
economic variables at critical time points across developed regions. We also
derive the corresponding asymptotic bands (the confidence intervals) for
orthogonal impulse responses function under standard assumptions.

Prediction [56.001808843574395]
Selective prediction aims to learn a reliable model that abstains from making predictions when uncertain.
Active learning aims to lower the overall labeling effort, and hence human dependence, by querying the most informative examples.
In this work, we introduce a new learning paradigm, active selective prediction, which aims to query more informative samples from the shifted target domain.

We consider a dynamic model with the consumers' preferences as well as price sensitivity varying over time.
We measure the performance of a dynamic pricing policy via regret, which is the expected revenue loss compared to a clairvoyant that knows the sequence of model parameters in advance.
Our regret analysis results not only demonstrate optimality of the proposed policy but also show that for policy planning it is essential to incorporate available structural information.
