M ethodological issues on calculating total-factor productivity index

This document explores the methodological issues in calculating the Total Factor Productivity (TFP) Index, with particular emphasis on the relationship between inputs and outputs in economic measures. It discusses various productivity measures, including the productivity index and the impact of different approaches like gross output versus value added. The paper outlines challenges related to price indices, commodity taxes, and measuring outputs in service sectors. Additionally, it examines labor measurement issues and capital service flows, highlighting the implications for accurate productivity assessments.

  1. Methodological issues on calculating total-factor productivity index Borut Kodrič

  2. Productivity : Input-output coefficient : Output produced : Input needed

  3. Productivity measures

  4. Productivity index • The economic andaxiomatic approaches to choosing an index number formula

  5. Measuring output • Gross output vs. value added • Problems: • Price indeces data • Commodity taxes data • Measuring output in service sector • Measuring intersectoral flows of contracted labour services or rented capitalequipment

  6. Measuring labour • Number of employed persons • Hours actually worked • Alternative: Hours paid or full-time equivalents • Problems: • Self-employed persons • Differences in the contribution of different types oflabour

  7. Measuring capital • Flows of the quantity of capital services are not usually directly observable (Productive stock of capital) • User cost of capital

  8. Productivity index :represents the share of input i in the total value of inputs :represents the share of VAin the total VA

  9. Results Table 1:Capital-labour productivity index (2000=100, Laspeyers)
