DESCRIPTION:*My research focuses on measuring the inequality of ordinal var
 iables. In this presentation\, I will reiterate the problem highlighted by 
 Alisson and Foster (2004) when trying to measure the inequality of such var
 iables. I will discuss the solutions proposed in the literature\, focusing 
 specifically on the article by Gravel and al (2021)\, in order to introduce
  new measurement tools.**Trade continues to be impeded by borders and dista
 nce to a puzzling degree. An influential (but untested) theory attributes t
 his underperformance of trade to an insufficient number of 'pioneer' firms 
 that create new trade links. This paper provides the first causal evidence 
 of the effect of individual pioneers on aggregate trade and growth. I compi
 le all 1.4 million sea captain voyages between Baltic Sea ports and the res
 t of the world from 1500 to the 1850s. For identification\, I exploit event
 s at sea that affect individual captains\, such as the temporary obstructio
 n of ports by sea ice\, which forces captains to pioneer new ports. I find 
 that the pioneering of an individual captain spills over to the total trade
  of a town\, increasing it by 2 to 4\\%. These effects are even greater whe
 n sea ice forces captains to become pioneers. I show that this is due to th
 e pioneering of more distant ports in terms of kilometers\, religion\, lang
 uage\, and product mix. In the absence of forced experimentation\, pioneers
  select \\textit{less} distant ports\, which tend to be less successful. To
 gether\, these findings demonstrate the effects of individuals (and their b
 ehavioral biases) on aggregate trade and growth. For policy\, this suggests
  that even small interventions that promote pioneering in distant destinati
 ons can have large effects.\\n\\nContact: Lucie Giorgi: lucie.giorgi[at]uni
