Biography

I am an applied economist. In my research, I try to understanding interactions between labor markets, the safety net and determinants of income and consumption inequality. I am PI on several grants from the Norwegian Research Council, a research fellow at IZA. I am also an associate editor of JEEA.

Labor supply responses to learning the tax and benefit schedule.

111(11) , s. 3733- 3766. Doi: https://doi.org/10.1257/aer.20201877

Despite the implications for policy, empirical evidence on the relative importance of factors that shape labor supply responses is missing. This paper helps fill this gap and quantifies the role of information frictions versus other frictions by combining notches in the Norwegian welfare system and quasi-experimental variation in access to information about the slope and location of kinks. While we estimate a frictionless elasticity of 0.3, overall frictions attenuate this elasticity by about 70 percent. We find the information letter increased the earnings elasticity from 0.06 to 0.15, implying that information frictions account for at least 30 percent of total attenuation.

Disability Benefits. Consumption Insurance. and Household Labor Supply

109(7) , s. 2613- 2654. Doi: https://doi.org/10.1257/aer.20151231

There is no evaluation of the consequences of Disability Insurance (DI) receipt that captures the effects on households' net income and consumption expenditure, family labor supply, or benefits from other programs. Combining detailed register data from Norway with an instrumental variables approach based on random assignment to appellant judges, we comprehensively assess how DI receipt affects these understudied outcomes. To consider the welfare implications of the findings from this instrumental variables approach, we estimate a dynamic model of household behavior that translates employment, reapplication, and savings decisions into revealed preferences for leisure and consumption. The model-based results suggest that on average, the willingness to pay for DI receipt is positive and sizable. Because spousal labor supply strongly buffers the household income and consumption effects of DI allowances, the estimated willingness to pay for DI receipt is smaller for married than single applicants.

Monthly Earnings Volatility and Household Pooling

[Conference Lecture]. Event

This paper examines monthly earnings volatility and its transmission to household earnings volatility using data from Norway on the universe of monthly employment and pay histories linked to household members. In the first part of the paper, we document substantial month-to-month changes in earnings: within a job, while a quarter of months have no earnings changes, another quarter have at least a 23\% change in earnings. Accounting for multiple-job holdings and spells of non-employment increases volatility, while further aggregating from the individual to the household level reduces volatility by 19-30\%. In the second part of the paper, we explore the roles of spousal insurance, assortative matching, and income pooling through event study analyses of job loss and couple formation as well as decomposition and bounding exercises. We show that virtually all of the decrease in volatility at the household level can be attributed to earnings pooling rather than to who marries whom or to behavioral responses to shocks.

How Broadband Internet Affects Labor Market Matching

[Report Research].

How the internet affects job matching is not well understood due to a lack of data on job vacancies and quasi-experimental variation in internet use. This paper helps fill this gap using plausibly exogenous roll-out of broadband infrastructure in Norway, and comprehensive data on recruiters, vacancies and job seekers. We document that broadband expansions increased online vacancy-postings and lowered the average duration of a vacancy and the share of establishments with unfilled vacancies. These changes led to higher job-finding rates and starting wages and more stable employment relationships after an unemployment-spell. Consequently, our calculations suggest that the steady-state unemployment rate fell by as much as one-fifth.
