Working Papers

Seria wydawnicza WNE WORKING PAPERS prowadzona jest przez WNE UW od 2008 r. i jak dotąd opublikowano w niej ponad 400 prac.

Seria WNE Working Papers służy szybkiemu upowszechnianiu wyników badań prowadzonych na Wydziale Nauk Ekonomicznych UW. Publikowane tu teksty mają charakter wersji roboczych (pre-printów): mogą być uzupełniane lub poprawiane w miarę postępu prac nad tekstem i procesu wydawniczego. Prezentujemy aktualną wersję udostępnioną przez autorów, opatrzoną datą oraz identyfikatorami DOI/ISSN – co ułatwia jej cytowanie i śledzenie kolejnych iteracji. Każdy dokument zachowuje pełne prawa autorskie swoich twórców, a w przypadku późniejszych zmian, autorzy mogą w dowolnym momencie zamieścić zaktualizowany plik lub wskazać miejsce ostatecznego wydania.

Do serii WORKING PAPERS przyjmowane są artykuły pracowników naukowych WNE UW oraz publikacje z konferencji organizowanych na WNE UW. Artykuły powinny dotyczyć ekonomii, mieć charakter oryginalnych prac badawczych, nie być wcześniej publikowane. Przyjmowane są wyłącznie teksty w języku angielskim.

Prace prosimy przesyłać e-mailem na adres: Po*n!SxZRkm/q96?J.E&g\3t`h0]#[H_wZiB`K0\S|eT.*+77{pBrjiYw

Prosimy przesyłać dwa pliki:

(1) główny tekst bez podania tytułu artykułu oraz autorów (plik DOC/DOCX) oraz

WP493. Is smooth Energiewende possible? Improving the performance of climate policies in Germany by optimizing the risk of electricity delivery

The Energiewende is a deep-rooted notion in the German economy. The main goal is to achieve climate neutrality by transitioning to renewable energy sources. However, the feasibility of this transition is partially hindered by power grid congestion, which undermines system efficiency and leads to both economic and environmental costs. We address this issue by making a prediction of the likelihood of congestion occurrence within the German TenneT DE electricity network in the years 2020-2023. We propose a twofold approach offering a combination of advanced econometric models and state-of-the-art machine learning methods. We offer separate solutions for up congestion when additional energy needs to be pushed to the network as well as down congestion when energy needs to be pulled away from the network. Analyzing the CatBoost with XAI, we identify factors that play a significant role in driving redispatch events within the German electricity network.

WP462. Carbon taxes in Europe do not hurt the poor

This study investigates the distributional impacts of carbon taxes, traditionally examined through simulation studies on the regressivity of hypothetical tax scenarios. However, the dy-namic influence of actually implemented carbon taxes on consumption/income poverty and inequality in a cross-country setting has been less scrutinised. This paper assesses the effect of carbon taxes introduced in the past three decades in 15 European countries on consumption shares of the lowest decile groups, poverty rates and inequality indices. The analysis shows that a $40/ton CO2 tax covering 30% of emissions leads to a consumption share increase of up to 4% for the bottom 20% and 40% of the population, a trend that persisted for five years post-implementation, particularly in nations that efficiently redistribute carbon tax revenues. This resulted in a modest reduction in consumption inequality over three years. In contrast, the impact of carbon taxes on income poverty and inequality is not statistically significant. These findings suggest that concerns about poverty and inequality due to carbon taxes can be miti-gated by implementing a moderate tax combined with a strategically efficient revenue redis-tribution mechanism.

WP78. Economic effects of differentiated climate action

We analyze existing definitions of carbon leakage and provide a new rigorous one. This is then tested using computable general equilibrium analysis for unilateral carbon dioxide abatement programs in the EU. Our model of the global economy is disaggregated into three regions. The analysis includes a decomposition of change in carbon emission. While some anti-leakage measures reduce carbon leakage significantly, some of them are less effective. We identified a list of parameters which affect not only the magnitude but also the sign of carbon leakage rate. Manipulating with elasticities of substitution in production function suggests that in reaction to the unilateral action of the EU, the other regions may both increase or decrease their carbon emissions. Even though we are positive about computable general equilibrium models' application in this policy area, their policy simulations cannot be directly treated as policy recommendations without a careful validation of their assumptions.
