European Symposium on Policy Modelling: Carbon Tax, Cross-border social security, Inequality, and Pension systems

Conference

English

European Symposium on Policy Modelling: Carbon Tax, Cross-border social security, Inequality, and Pension systems

When:

WED, 25 MAR 2026

From:

8:30 AM

To:

6:30 PM

Context

On 25 March 2026, LISER will host a one‑day symposium within the Erasmus+ project ecoMod – capacity building in environmental and economic policy modelling and data analysis initiative, complemented by dedicated sessions funded by the FNR-CORE project SPIN. The event brings together researchers working on cross-border tax-benefit modelling, carbon taxation, inequality, and pension reforms across Europe.

The programme is organized into three thematic clusters, and brings experts from IGSS, Institute of Public Finance (Croatia), JRC-Seville, LIS, LISER, STATEC, Universidad Loyola Andalucía, University of Friburg, University of Liechtenstein, and University of Luxembourg:

Carbon taxation, cost‑of‑living pressures, and policy responses
New evidence on VAT pass‑through and distributional effects; universal basic income as a stabilizer; cross‑border tax–benefit coordination; gender dimensions of carbon emissions. A dedicated segment by the Luxembourg Income Study (LIS) introduces new consumption data.
Inequality across time, space, and countries
Advances in income‑generation models; municipal‑level population modeling; AI‑enhanced methods for inequality research; pathways to combine micro- and macrosimulation models.
Pension systems and reforms
A new typology of pension system designs; Luxembourg‑specific pension system diagnostics; policy analysis of pension reform scenarios using dynamic microsimulation models for Germany and Switzerland.

Organizing committee

Denisa M. Sologon

Senior Research Scientist

Denisa M. Sologon holds the position of Senior Research Scientist at the Luxembourg Institute of Socio-Economic Research (LISER). Her research programme involves quantitative approaches to welfare economics, in particular income inequality, income distribution dynamics, taxation, social policy and social protection, social mobility, environmental policy and health. A key theme in her work is understanding the social, economic, and policy drivers of inequality. Her main interests are in the development and application of policy microsimulation models and the quantitative analysis of large data sources (administrative, survey) to aid the design, evaluation and improvement of public policy.
