In Simple Words
To measure raw athletic skill fairly, all runners are brought to an identical indoor track with identical shoes and weather conditions, removing outside variations so only pure speed and technique are measured.
Small rug firms in Fowa
- No export opportunity offered
- Group used for comparison
- Export opportunity offered
- Faster production and higher quality
With identical looms, inputs and specifications, export-offer firms produced rugs faster and with higher quality. 2014 lab task with identical equipment and inputs. No absolute task outcomes reported here.
See source →Research question
Evaluating true firm productivity gains in natural field settings is confounded because export orders demand more complex specifications, higher thread counts, and costlier inputs than domestic products.
Participants
N = 219 small rug-producing firms with fewer than 5 employees operating in Fowa, Egypt.
Study Design
Controlled experimental task in a neutral rented workshop ("quality lab") where treatment and control firms produced identical rugs using identical looms and input materials.
Results
When equipment and specifications were held identical, exporting firms produced rugs faster and achieved higher quality scores across 11 master artisan evaluation dimensions.
Takeaway
Assess producer technical efficiency gains by testing treatment and control subjects under identical workshop conditions with standardized materials.
