Article
We study the dual role of active labor market policies: First, ALMP may perform a screening role by increasing job-search incentives, especially among individuals with good labor market prospects, already before program participation. Second, actual program participation may help individuals with poor labor market prospects. We examine whether this...

We discuss typical issues in getting access to and using high-quality administrative tax data for research purposes. We discuss research involving both quasi- and field experiments implemented together with the tax authority. We reflect on practical solutions that promote co-creation of knowledge and reduce information asymmetries between researche...
Article

We provide an analysis of the revenue-maximizing top earned income tax rate for a country with one of the highest levels of earnings taxation in the world, Finland, and compare it to the current level of taxation. We account for the effect of income-shifting possibilities in the calculations and find that the current top tax rate on earnings in Fin...
Article
We estimate the private returns to being elected to parliament or to a municipal council using a regression discontinuity (RD) design. We first present a bootstrap method for measuring the closeness of elections, which can be applied to any electoral system. We then apply the method to perform a RD estimation in Finland, where seats are assigned ac...
Article
We study the returns to political o¢ ce using data from Finnish parliamentary elec-tions in 1970-2007 and municipal elections in 1996-2008. The discontinuity of electoral outcomes in individual candidate votes allows us to estimate the causal e¤ect of being elected on subsequent income. Getting elected to parliament increases annual earnings initia...
Article
We analyze attempts to implement personalized regulation in the form of sin licenses (O’Donoghue and Rabin 2003, 2005, 2007) to correct the distortion in the consumption of a harmful good when consumers suffer from varying degrees of self-control problems. We take into account the possibility that consumers may trade the sin good in a secondary mar...

This paper examines the effects of health-oriented food tax reforms on the distribution of tax payments, food demand and health outcomes. Unlike earlier work, we also take into account the uncertainty related to both demand estimation and health estimates and report the confidence intervals for the overall health effects instead of only point estim...
Article
A growing theoretical literature on the effect of politicians' salaries on the average level of skills of political candidates yields ambiguous predictions. In this paper, we estimate the effect of pay for politicians on the level of education of parliamentary candidates. We take advantage of an exceptional reform where the salaries of Finnish MPs...
Article
We analyse the determination of taxes on harmful goods when consumers have self-control problems. We show that under reasonable assumptions, the socially optimal corrective tax exceeds the average distortion caused by self-control problems. Further, we analyse how individuals with self-control problems would vote on taxes on the consumption of harm...
Article
When consumers make mistakes, the government may wish to use paternalistic taxation as a corrective measure. We analyse the extent to which tax competition undermines the feasibility of paternalistic taxation. We show that the paternalistic component of a tax on a harmful good is reduced when there is cross-border shopping, but it does not disappea...
Article
We analyse the determination of taxes on harmful goods when consumers have self-control problems. We show that under mild conditions, the socially optimal tax rate exceeds the average distortion caused by self-control problems. Further, we show that in most cases the tax rate chosen in political equilibrium is below the socially optimal level.
Article
We show that the burden of sin taxes does not necessarily fall most heavily on individuals with the highest level of consumption and derive a condition for cases where sin taxes improve individual welfare. We further argue that taxes on goods such as unhealthy food can be progressive when consumers have time-inconsistent preferences.
Article
We examine the effect of publicly provided health care on welfare by combining local level data on public health care, and individual level data on life satisfaction. It is shown that relatively high expenditures in health care have a positive effect on individuals' life satisfaction in our data. We further illustrate how life satisfaction data can...
Article
We consider a model with a vertically integrated monopolist network provider who faces rival operators in the retail market. We examine the network operator's incentives for infrastructure investment. We find that investments are below the social optimum even when there is no regulation, and access price regulation further reduces investment incent...
Article
This study reviews the key economic features of the telecommunications industry and outlines two benchmark models that have been developed in previous literature for introducing competition into local telecommunications. One possibility is services based competition, where entrant telephone operators have no network of their own, and another is fac...

This project examines the effect of pay for politicians on candidate quality, as well as private returns to political office. Our 2007 paper on candidate quality was the first paper to show that the effects of pay for politicians on candidate quality can be non-monotonic. Subsequent papers tested the theory using a salary reform in Finland, as well as estimated the causal effect on income of being elected to the parliament or to a municipal council.
