Activation against absenteeism – Evidence from a sickness insurance reform in Norway, published in Journal of Health Economics Volume 62, November 2018, Pages 60-68

Or why you should take courses that are not for credit and do presentations in class.

In the spring of 2015, I followed a course in microeconometrics at the Department of Economics at the University of Oslo to learn some more econometrics. As part of the course, the students had to present published papers employing the methods from the course. I volunteered to do two such presentations, that both ended up as papers of my own!

For my first presentation, which was on the synthetic control method (SCM), I asked the instructor for that lecture, Tarjei Havnes, if I in stead could present an application of my own. I did not know much about the SCM from before, but in the lecture I noticed that it would fit very well to a recent sickness absence reform in a Norwegian region I had head about from Knut Røed, a colleague at the Frisch Centre. The fact that the seminar schedule was on a few weeks lag from the lectures gave me some time to implement a basic analysis of the reform and put together a presentation. The subsequent positive feedback in the seminar motivated me to develop it into a proper paper, which is now just published in the Journal of Health Economics. The paper if of course much extended since that seminar, but the core remained the same.

The reform in question was a program undertaken by the Norwegian region of Hedmark in 2013. It was aimed at strictly enforcing a requirement that people on long-term sick leave be partly back at work unless explicitly defined as an exception. I found that the reform reduced sickness absenteeism by 12% in the reform region compared to a comparison unit created by a weighted average of similar regions. Thus, making use of the partial work capacity of temporary disabled workers has the potential to reduce long-term absenteeism and bring down social security costs. 

A key graph is below, showing how actual absenteeism in Hedmark (solid line) after the reform diverged from the estimate of absenteeism in the absence of reform (dashed line): 

Fig. 1. Trends in the sickness absence rate in Hedmark and the synthetic control region. Note: The dotted line at the fourth quarter of 2011 indicates the final quarter of the matching period. The dashed line at the second quarter of 2013 indicates the period in which the activation program was introduced.

    The effect is driven by both increased part-time presence of temporary disabled workers and accelerated recovery. Musculoskeletal disorders was the diagnosis group declining the most. I conclude that such an activation strategy represents an alternative to traditional attempts at welfare reform involving stricter screening or reductions in generosity, and may be more compatible with already existing legislation and obligations, as well as easier to find support for across political priorities.

    The paper is freely available for a month here.


    Television, Cognitive Ability, and High School Completion, forthcoming in The Journal of Human Resources

    One and a half years ago, I blogged about a working paper by Simen Markussen, Knut Røed and myself showing that access to commercial television channels during childhood and adolescence reduced cognitive ability scores and high school graduation rates of Norwegian men. Now, a substantially revised version is forthcoming in The Journal of Human Resources. (Preprint here.) The effects appear to be driven by consumption of light television entertainment crowding out more cognitively stimulating activities.

    Can Welfare Conditionality Combat High School Dropout? Forthcoming in Labour Economics

    Two years ago, I blogged about a working paper on conditions for welfare and high school completion by Simen Markussen, Knut Røed and myself. The paper is now finally accepted for publication and is forthcoming in Labour Economics. The final version is here, freely downloadable until the beginning of October. An updated working paper version can be found here.

    “Is there really an empirical turn in economics?”

    The recent “empirical” turn in economics should be known as an “applied” one and it is just one in a long series of related developments. Moreover, it is a move towards the historical roots of the discipline. Those are some lessons from Beatrice Cherrier‘s essay “Is there really an empirical turn in economics?“. Based on research conducted together with Roger Backhouse, she takes issue with the idea that there has been a revolution in economic research involving empirics. Some points I liked:

    • Empirical work has been live and well, what has changed is its recent larger role in top journals. Besides, the view of theory as dominating in economics is based on looking only at the last 50 years – pre- and immediate post-war economics used to be a lot more empirical.
    • Much theory has become more applied, often involving data. And John Bates Clark medal citations stress “applied,” often taken consisting of a mix of theory and empirics.
    • Increasing availablity of data is a development that has been ongoing since at least the 1960’s. Hype around and criticism of new, large sources of data were the same in the 1970’s as today.
    • Computerization is overrated, much modern empirical work is computationally and numerically very simple.
    • Oscar Morgenstern (of von Neumann and Morgenstern‘s Theory of Games and Economic Behavior fame) proposed that to become a fellow of the Econometric Society, it should be a requirement to “have done some econometric work in the strictest sense” and be “in actual contact with data they have explored and exploited for which purpose they may have even developed new methods.”

    Television, Cognitive Ability, and High School Completion

    That is the title of a just released working paper by Simen Markussen, Knut Røed, and myself. We show that access to commercial television channels during childhood and adolescence from the 1980’s onwards in Norway reduced cognitive ability scores and high school graduation rates of young men.

    In a comment, Pat Sharp apologizes (true story! thanks to @JFiva).

    “Can welfare conditionality combat high school dropout?”

    I have a new working paper out, joint work with Simen Markussen and Knut Røed. Simen has written provocatively about the paper in the today’s Dagens Næringsliv, which is also running a companion piece. These are only in Norwegian (and behind a paywall), however, so here is a brief summary in English:

    We investigate what happens when Norwegian social insurance offices increase their use of conditions would-be welfare recipients need to satisfy in order to receive welfare. Using the staggered introduction of this program and based on double and triple difference models, we find that such conditionality reduces the number of young people that receive welfare, and more importantly, increases the high school graduation rate. For young people from disadvantaged backgrounds, we find substantial and precise effects, whereas we find no effects on youth from more resourceful backgrounds, as expected. A few years later, we find that those who were exposed to new regime have more education, earn more, and are more likely to be employed. Thus even though activating these people may cost something upfront, it pays off in the long run.

    The newspaper has an interview with a guy who got on track and gets some work experience through this system. Here is the abstract of the research paper:

    Based on administrative data, we analyze empirically the effects of stricter conditionality for social assistance receipt on welfare dependency and high school completion rates among Norwegian youths. Our evaluation strategy exploits a geographically differentiated implementation of conditionality. The causal effects are identified on the basis of larger-thanexpected within-municipality changes in outcomes that not only coincide with the local timing of conditionality implementation, but do so in a way that correlates with individual ex ante predicted probabilities of becoming a social assistance claimant. We find that stricter conditionality significantly reduces welfare claims and increases high school completion rates.

    Basic income pilot in Finland, headed by top economist

    Via MarginalRevolution’s assorted links and others, a short BBC article about a pilot project in Finland on universal, basic income. Economist Ohto Kanninen, coincidentally a fellow student of mine from graduate school, describes the project:

    The prime minister has expressed support for a limited, geographical experiment. Participants would be selected from a variety of residential areas.

    Mr Kanninen proposes testing the idea by paying 8,000 people from low income groups four different monthly amounts, perhaps from €400 to €700.

    They also have the Prime Minister on board:

    Prime Minister Juha Sipila has praised the idea. “For me, a basic income means simplifying the social security system,” he said.

    This sounds really exciting, and I cannot wait to see the working paper.
