Climbing Bloom's Ladder

Climbing the Technology Ladder Too Fast ?

This paper provides a star comparison of manufacturing productivity levels in China, India, Indonesia, South Korea and Taiwan with the US as the reference country for the period 1963-1993. South Korea and Taiwan showed prolonged catch up in labour productivity with the US, whereas the other countries had long periods of relative stagnation. This is reflected in relative performance of seven det...

Climbing a shaky ladder: Better adaptive risk estimation

We revisit the leaderboard problem introduced by Blum and Hardt (2015) in an effort to reduce overfitting in machine learning benchmarks. We show that a randomized version of their Ladder algorithm achieves leaderboard error O(1/n0.4) compared with the previous best rate of O(1/n1/3). Short of proving that our algorithm is optimal, we point out a major obstacle toward further progress. Specific...

Climbing the electricity ladder generates carbon Kuznets curve downturns

This paper examines why some countries have experienced environmental Kuznets curve (EKC)-type reductions in carbon dioxide (CO2) emissions, while others have not. The hypothesis that climbing to the upper rungs of the electricity ladder (nuclear power and modern renewables) has been the primary mechanism via which countries have achieved substantial reductions in per capita CO2 emissions is te...

Climbing the Job Ladder: New Evidence of Gender Inequity

Climbing the Job Ladder: New Evidence of Gender Inequity An explanation for the gender wage gap is that women are less able or less willing to ‘climb the job ladder.’ However, the empirical evidence on gender differences in job mobility has been mixed. Focusing on a subsample of younger, university-educated workers from an Australian longitudinal survey, we find strong evidence that the dynamic...
