Modern supply chains don't look like trade theory 101!

They involve constant border crossings, each now hit by tariffs.

Tariffs raise prices, but the more important thing they do is disrupt supply relationships.

1/ have been waiting for this paper for ages. Rounding is common in elicited beliefs (.50, .75…). Does it bias estimation of weights on prior (delta) and likelihood (beta)?
Yes: when rounding is less frequent, delta, beta are closer to 1 (=Bayes). A fix is given

I like Ryan’s paper and (obviously) I think complexity matters for behavior.

But I think Florian’s updating too much from one experiment. I want to see replications and results from β€˜nearby’ designs before saying the lottery anomalies have nothing to do with risk.

Permanent designs like this can make bike infrastructure feel as natural and normal as sidewalks. Here’s a small city in Quebec (just west of Quebec City) with a population of 20,000.

Economic valuations fluctuate in ways empirical research cannot fully explain

What information are we missing? Economic theories emphasize the role of hard-to-quantify beliefs and perceptions

My job market paper develops algorithms + measurement to quantify perceptions of firms

My favorite kind of behavioral economics. Take a simple deviation from the standard properties of learning and explore all of its strategic implications.

We observe a general decrease of null results across most fields in the post-2000 period. 

    Highest levels: Fields such as Econometrics and Behavioural Economics report higher shares of null results.

    Health Economics shifted from least to one of the highest reporter of Nulls.

Health economics is doing something right
