Teen taloustieteen väitöskirjaa Helsingin Yliopistolla. Keskityn erityisesti energiamarkkinoiden ja uusiutuvan energian tutkimukseen, minkä lisäksi minulla on tällä hetkellä käynnissä tutkimusprojektit eläintuotannon tukiin sekä työmarkkinoiden keskittymiseen liittyen.
Väitöstyötäni ohjaavat professorit Hannu Vartiainen ja Lassi Ahlvik.

Limits of Renewable Energy Growth and the Equilibrium Effects of Green Industrial Technologies
2026
Working paper, PhD article
Abstract: Variable renewable energy (VRE) can be used to produce electricity with lower private and social costs than fossil fuels, but their growth is limited by a strong price cannibalization effect due to the characteristics of electricity markets. We build a partial equilibrium model to analyze wind turbine expansion using data from a country with a high share of VRE and show that we can calculate a saturation point as a share of total electricity generation after which further wind expansion is no longer profitable. Earlier literature has suggested electrical energy storage (EES) and increased demand flexibility as solutions to integrate more VRE to the grid. Although such solutions can increase the quantity of VRE consumed, we find that under the existing market conditions these solutions can also lower the saturation point and dampen incentives for further VRE expansion in the external margin.
Discrete Choice Under Congestion
2026
Under peer review
Joint with Debopam Bhattacharya (University of Cambridge)
Abstract: We model discrete choice settings where capacity-constraints on the supply side cause the expected utility from choosing an alternative to decline as more individuals choose it, e.g. overcrowding in rush-hour trains. We discuss existence/uniqueness of equilibrium, identification of preferences and distribution of welfare change resulting from a switch to (i) centralized random, and (ii) centralized utilitarian allocations, which eliminate congestion but also curtail individual freedom of choice. We also show how to compute welfare effect of congestion pricing. We illustrate our methods with an application to choice of college in Cambridge by undergraduate admission candidates. Extensions to behavioral settings and covariate-dependent success probabilities are briefly discussed.
Labour Market Concentration and Worker Mobility: Evidence from Online Vacancies
2023
UCL Journal of Economics
Stone Center Award for Research in Economic Inequality
Abstract: This paper uses big data on German online vacancies to investigate the impact of local labour market concentration on wages. Herfindahl-Hirschman Indexes are calculated based on the number of vacancies posted by firms in geographic-occupational labour markets. Based on IV results, a 1% increase in labour market concentration decreases posted wages for full-time employees by 0.098%. Workers who can work remotely do not face negative wage effects from labour market concentration suggesting that worker mobility can mitigate the negative wage effects of labour market concentration. While most vacancies occur in competitive labour markets, rural areas exhibit notable concentration.
