Functional Structure in Production Networks [PDF]

Frontiers in Big Data, 2021
Production networks are integral to economic dynamics, yet dis-aggregated network data on inter-firm trade is rarely collected and often proprietary. Here we situate company-level production networks within a wider space of networks that are different in nature, but similar in local connectivity structure.

Some Unpleasant Markup Arithmetic: Production Function Elasticities and their Estimation from Production Data

Journal of Monetary Economics, 2020
The ratio estimator of the markup is the ratio of the output elasticity for a flexible input to that input’s cost share in total revenue. We highlight identification and estimation issues pertaining to this ratio estimator, when firm-level output prices ...

Effects of different feeding rations on the CO2 fluxes at water-air interface and energy budget of sea cucumber Apostichopus japonicus (Selenka)

Aquaculture Reports, 2023
Feeding ration is one of the most important factors that directly affect growth and physiology progress of sea cucumber Apostichopus japonicus. In present study, a 32-day experiment was carried out to investigate the effects of feeding ration (1%, 3 ...
