We offer a contribution to the analysis of optimal monetary policy. The standard approach to determine what policy rule a central bank should follow is to take a single structural model and minimize the unconditional volatilities of inflation and real activity. In this paper, we propose monetary...

We construct a narrative instrument for government investment from official records in Germany. Using structural vector autoregressions, we document a significant crowding-in of private investment and an output multiplier of roughly 2. Then, we match a New Keynesian dynamic stochastic general...

Star variables, such as potential output and the neutral real interest rate, are fundamental to economic policymaking but challenging to identify due to their latent nature. Buncic, Pagan, and Robinson (2023) highlight the difficulty of identifying star variables within short macroeconomic...

This paper describes the structure and estimation of a structural macro-econometric model of the Northern Ireland economy. We show how it can be used to assess the potential impact of economic shocks and policy changes. Specifically, we have done so by examining the effects of shocks to UK...

Is the harmonization of different food standards between countries in the context of free trade agreements exclusively positive, or is there a risk of high social costs for consumers? The harmonization of different national regulations plays an important role in contemporary trade policy. In...

The benefits provided by ecosystem services, such as crop pollination and water purification, are of great importance to any economy, both directly and indirectly. Therefore, nature-inclusive decision-making requires that such benefits are taken into account in the economic decision-making...

Identifiability of the parameters is an important precondition for consistent estimation of models designed to describe empirical phenomena. Nevertheless, many estimation exercises proceed without a preliminary investigation into the identifiability of its models. As a consequence, the estimates...

This paper develops G3MOD, a semi-structural gap-trend model designed for frequent external sector forecasts crucial in macroeconomic forecasting. Focused on the G3 economies (US, Euro Area, and China) and the rest of the world, G3MOD leverages insights from central banks' policy models, to...

The paper documents the latest extensions of the Bank of Ghana's Quarterly Projection Model (QPM), used regularly to produce policy analysis and forecasts in support of the Bank's policy processes. The decomposition of GDP allows to separate the agriculture and oil sectors, driven by exogenous...

The calibration of monetary policy is particularly challenging at a time of large shocks. Interest rates in Hungary rose sharply in response a significant increase in inflation and depreciation in the forint in 2022. As inflationary pressures have eased, the base rate has been reduced but...

This paper applies the semi-structural model proposed by Bernanke and Blanchard (2023) to analyse wage growth, price inflation and inflation expectations in the euro area. It is part of a broader project coordinated by Bernanke and Blanchard to provide a unified framework for analysing and...

This paper takes stock of the ECB's macroeconometric modelling strategy by focusing on the models and applications used in the Forecasting and Policy Modelling Division. We focus on the guiding principles underpinning the current portfolio of the main macroeconomic models and illustrate how they...

This article presents a comprehensive study on developing a predictive product pricing model using LightGBM, a machine learning method optimized for regression challenges in situations with limited historical data. It begins by detailing the core principles of LightGBM, including decision trees,...

Im Rahmen eines Forschungsvorhabens für das BMWK hat die GWS zusammen mit Prognos die gesamtwirtschaftlichen Effekte von Klimaschutzmaßnahmen berechnet. Die direkten Wirkungen der Maßnahmen im Energiebereich sind in bottom-up Modellen der Prognos AG ermittelt worden. Die...

Modeling of non-carbon dioxide (non-CO2) greenhouse gas (GHG) emissions in integrated assessment models (IAMs) is critical to achieving long-term climate targets. This study selects nine IAMs to reveal the modeling mechanisms and mitigation of non-CO2 GHGs. It further explores the impact of...

This paper shifts studies on macroeconomic models from a national to a regional scope. Regions, indeed, often follow growth trajectories that dif- fer greatly from others within the same country. In this study we propose a macroeconometric model for 20 economies corresponding to the Italian...
