En vanlig missuppfattning när det gäller oönskad variabilitet i bedömningar är att det inte spelar någon roll eftersom slumpfel tar ut varandra. Det stämmer att positiva och negativa fel i en bedömning av samma fall mer eller mindre tar ut varandra och vi kommer att diskutera mer i detalj hur denna omständighet kan utnyttjas för att minska bruset. Men brusiga system gör inte flera bedömningar av samma fall. De gör brusiga bedömningar av olika fall. Om en försäkring har för hög...

Is an economics degree really worth it? .[embedded content] A science that doesn’t self-reflect on its own history and asks important methodological and science-theoretical questions about its own activity is in dire straits. Already back in 1991, a commission chaired by Anne Krueger and including people like Kenneth Arrow, Edward Leamer, and Joseph Stiglitz, reported from their own experience “that it is an underemphasis on the ‘linkages’ between tools,...

For the one, it is a demonstration of the greatness of Europe; for the other, a reminder that its ideals are tainted by racism and colonialism. Both miss the importance of the non-European world in shaping many of the ideas we associate with the Enlightenment....

Debating econometrics and its shortcomings yours truly often gets the response from econometricians that “ok, maybe econometrics isn’t perfect, but you have to admit that it is a great technique for empirical testing of economic hypotheses.” But is econometrics — really — such a great testing instrument? Econometrics is supposed to be able to test economic theories. But to serve as a testing device you have to make many assumptions, many of which themselves cannot be tested or...

What has always bothered me about the “experimentalist” school is the false sense of certainty it conveys. The basic idea is that if we have a “really good instrument” we can come up with “convincing” estimates of “causal effects” that are not “too sensitive to assumptions.” Elsewhere I have written  an extensive critique of this experimentalist perspective, arguing it presents a false panacea, andthat allstatistical inference relies on some untestable assumptions … Consider...
