There has been increased interest in the use of "big data" when it comes to forecasting macroeconomic time series such as private consumption or unemployment. However, applications on forecasting GDP are rather rare. In this paper we incorporate Google search data into a Bridge Equation Model, a...

Firms often offer a menu of contracts which vary by fee structures in order to differentiate among different types of consumers. Such contracts require that consumers make estimates of their own future behavior to choose among service contracts whose prices condition on usage. We study the...

This study extends the hybrid version of the baseline New-Keynesian model with heterogeneous agents who may adopt various forecast heuristics. With a focus on consumer expectations, we identify the most appropriate pairs of forecast heuristics that can lead to an equivalent fit to the data...

In this study, we analyze the macroeconomic dynamics under various shocks in two competing frameworks. Given the baseline New-Keynesian model, we compare the impulse response functions that stem from the hybrid version under rational expectations with the ones obtained in the forward-looking...

The notion of bounded rationality has received a considerable attention in the midst of debate over the usefulness of various macroeconomic models. In this paper we empirically seek to analyze the baseline New-Keynesian model with heterogeneous agents who may adopt various heuristics used to...

Previous studies using consumer survey data on inflation expectations find that consumers revise their inflation forecasts approximately once every eight months, suggesting that information is quite "sticky." However, in the consumer survey data analyzed, respondents take the survey twice with a...

This paper proposes a measure of real-time inflation expectations based on metadata, i.e., data about data, constructed from internet search queries performed on the search engine Google. The forecasting performance of the Google Inflation Search Index (GISI) is assessed relative to 37 other...

This article studies the effects of the latest European regulations on carbon emissions on the Italian car market and discusses the possibility of achieving climate neutrality of road transport through the "mere" replacement of cars currently on the road with new zeroemission cars. Since 2016,...
