About

Hi! I am Sachintha and I am a PhD Student at the Martin Luther University Halle-Wittenberg (MLU), at the Chair of Econometrics and Empirical Economic Research. I am also an associated PhD Student at the Economics of Connected Natural Commons (ECO-N), University of Leipzig, and a Joachim Herz Stiftung Fellow since 2024.

My research is focused on measuring the efficacy of climate policies, both in terms of environmental effectiveness and well-being. I am also interested in research related to improving governance, accountability and socio-economic living conditions in Sri Lanka, where I am from.

Before starting my PhD, I worked as an Economist at Verité Research, an independent think tank based in Sri Lanka, where I also served as the Team Leader of the Economics unit. At Verité, I engaged in a variety of projects addressing issues such as youth unemployment, female labor force participation, social welfare policies, and agricultural policy. I collaborated with organisations including UNICEF, UNDP, the World Bank, the European Union, CIPE and the Sri Lankan Government. I continue to be affiliated with Verité Research.

I am always happy to collaborate or chat about research. Please feel free to get in touch!

Zero Fare, Cleaner Air? The Causal Effect of Luxembourg’s Free Public Transportation Policy on Transport Emissions

Environmental and Resource Economics, Vol. 89, Art. 45, 2026 · with Tobias Eibinger

Paper DOI

In March 2020, Luxembourg became the first country to make public transport free. We use this unique setting to evaluate the policy’s impact on transport emissions using a synthetic difference-in-differences framework. We use spatial emissions data to construct a panel of NUTS 2 regions in the EU from 2016 to 2022. We estimate an average reduction of 5.9% in road transport CO2 and overall road transport GHG emissions, with larger effects for NOx. These findings are robust against confounding shifts in working from home and commuting patterns, vehicle fleet electrification, and the localized effects of the COVID-19 pandemic. Complementary event-study evidence from automatic traffic counters and air quality stations through 2023 corroborates our findings and suggests larger effects on weekends.

Rising Waters, Falling Wellbeing: The Effects of the 2013 East German Flood on Subjective Well-Being

Accepted, Environmental and Resource Economics · with Katharina Kolb and Christoph Wunder

Paper

This paper employs a panel event study design to examine the causal effects of the 2013 flood disaster in East Germany on subjective well-being. We merge geo-spatial flood data with longitudinal data from the Socio-Economic Panel (SOEP) to identify individuals in affected municipalities. Our results show that those affected by the flood report a significant life satisfaction drop of 0.17 points on an 11-point scale, which is equivalent to a 2.5% fall from pre-flood levels, in the year after the flood. The effect is more severe in peripheral areas than in central areas, and for low-income individuals than for high-income individuals. However, the effect dissipates by 2015. Additionally, we observe a notable initial decrease in health satisfaction, followed by recovery, while financial satisfaction was largely unaffected.

Macro-level Worries in the Energy Transition: Insights from Germany's Coal Phase-out Regions

with Yasmine Bakr and Christoph Wunder · Draft available upon request

This paper studies how a major decarbonization policy affects macro-level worries about society. We examine Germany’s 2020 coal phase-out and its effects on worries about social cohesion, economic development, and climate change among residents of Eastern German lignite regions. Using longitudinal data from the German Socio-Economic Panel (2015-2023) and a panel eventstudy difference-in-differences design, we compare individuals in treated coal regions with residents of unaffected Eastern German districts before and after the legislation. We find substantial regional heterogeneity. In the Central German lignite region, the coal phase-out has little lasting effect on macro-level worries, with at most a temporary decline in economic worries. In Lusatia, by contrast, worries about social cohesion rise persistently after the policy, while economic worries show an immediate but unstable increase. Worries about climate change remain unchanged in both regions. The results show that decarbonization policies can reshape perceptions of society even when material compensation accompanies transition support.
