Despite extensive research, there is no agreement on the value of the elasticity of substitution between capital and labour at the aggregate or the industrial level. Utilizing 2,419 estimates from 77 studies published between 1961 and 2017, this paper provides the first meta‐regression analysis for the US economy. We show that the heterogeneity in previously reported estimates is driven primarily by modelling decisions for technological dynamics. Throughout the analysis, the hypothesis of a Cobb–Douglas production function is rejected. Based on our meta‐regression sample, we estimate a long‐run meta‐elasticity for the aggregate economy in the range of 0.45–0.87. Most industrial estimates do not deviate significantly from the estimate for the aggregate economy.

Three bottom habitats in Biscayne Bay were sampled by 120 trawl samples taken during both day and night from April to August 1963. Daylight samples contained 1,391 fishes representing 41 species. Night samples contained 1,440 fishes and 49 species. The number of species per sample followed a Poisson distribution, the number of individuals per sample followed a negative binomial distribution, and the number of individuals per species followed Fisher's logarithmic series. The following generalizations apply to both number of species and number of individuals. More fishes were taken in the Thalassia area than in the Thalassia-sand area, which in turn had more than the mud-sand area. More were taken at night than during the day. Tidal direction had no significant effect. Analysis of data on the sample variance for paired 2-minute samples showed that seven to eight replicates are needed to detect a difference of five species and 10 samples are needed to detect a 10% change in the number of individuals...
