Using the Smets and Wouters model as a baseline, we incorporate various survey-based measures of inflation expectations to evaluate their effects on model fit and forecasting accuracy. The framework is extended to include financial frictions, unemployment, time-varying inflation targets, and news shocks. Results show that incorporating observed inflation expectations improves model fit, reduces posterior uncertainty around shocks, and lowers reliance on ad hoc rigidities such as indexation and investment adjustment costs, particularly in case of U.S. data. However, these expectations do not consistently improve the model’s ability to replicate key macroeconomic moments. The magnitude and direction of improvements vary across model variants and between the U.S. and the Euro area. Robustness checks suggest that observed expectations help mitigate the effects of structural breaks. Overall, the findings enhance model predictions and challenge the sufficiency of relying solely on rational expectations in DSGE models.</div></div>","PeriodicalId":48419,"journal":{"name":"Economic Modelling","volume":"153 ","pages":"Article 107300"},"PeriodicalIF":4.7,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing literature emphasizes the utility of technical indicators and dimensionality reduction techniques, but it often overlooks nonlinear dynamics and the role of weak factors.

Empirical results show that sSUFF outperforms traditional methods both in-sample and out-of-sample. It remains robust across varying economic conditions and performs particularly well during periods of heightened market volatility, such as the COVID-19 pandemic and the Russia–Ukraine conflict. sSUFF’s advantage arises from its ability to capture nonlinear patterns and effectively distinguish between strong and weak predictors. Economically, sSUFF-based forecasts yield higher investor returns, highlighting their practical value in financial forecasting and their relevance to investment strategies, risk management, and policy decisions.</div></div>","PeriodicalId":48419,"journal":{"name":"Economic Modelling","volume":"153 ","pages":"Article 107295"},"PeriodicalIF":4.7,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145120784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extreme causality shock transmission indicates that the five assets may provide hedging and diversification opportunities at specific times.

A cross-sectionally augmented auto-regressive distributed lag model (CS-ARDL) is estimated using panel data that capture state-specific weather-output relationships, long-term impacts, temperature persistence, intra-annual variability, unobserved heterogeneity, and cross-regional spillovers. The findings reveal that, on average, a 1 °C annual temperature variation reduces economic growth by 3.89%, nearly twice the previous estimate. Second, results suggest that annual temperature variation diminishes growth by damaging productivity through reduced ecosystem services, labour, and capital efficiency.

This study evaluates whether and how the spatial correlation with central digital finance regions promotes income convergence, by employing a modified gravity model and data from Zhejiang Province in China. The empirical evidence shows that digital finance spatial correlation can contribute to income growth. Notably, low-income regions derive a stronger growth impetus by enhancing spatial correlation with central digital finance regions, narrowing the income inequality with high-income regions. Specifically, capital flow, technological innovation, and business creation are three effective mechanisms.

As the two instrumental variable models produce quantitatively different impulse responses for output, we empirically illustrate the importance of testing for invertibility and using the results to guide model selection.

To uncover the underlying mechanism, we construct a New Keynesian DSGE model with perpetual youth, showing that aging dampens monetary policy effectiveness primarily through the investment channel.
