Resource Misallocation in Turkey: A Detailed Summary

Core Content

This working paper by Ha Nguyen, Temel Taskin, and Ayberk Yilmaz analyzes resource misallocation in Turkey's manufacturing sector, focusing on how it affects total factor productivity (TFP). The study uses the framework developed by Hsieh and Klenow (2009) to estimate the potential gains in TFP if resources were allocated more efficiently within sectors, aligning with U.S. levels of efficiency.

Main Points

• Resource Misallocation in Turkey: The paper finds that resource misallocation in Turkey is substantial, with a hypothetical TFP gain of 24.5% in 2014 if capital and labor were reallocated to equalize marginal products to the U.S. level.

• TFP Growth Sources: TFP growth in Turkey has been driven by:

  • Technology adoption.
  • Factor reallocation from low-productivity sectors (like agriculture) to high-productivity sectors (like manufacturing and services).
  • Within-sector resource misallocation, where productive firms are unable to access sufficient resources and unproductive firms are larger than they should be.

• Improvement in Allocative Efficiency: Between 2003 and 2013, there was a significant improvement in allocative efficiency. However, this trend slowed after 2007, and in 2014, the earlier improvement reversed, with resource misallocation worsening.

• Sector-Specific Misallocation: The study identifies that misallocation is most pronounced in the textile, transport, food, and leather industries. These sectors show the largest gaps in productivity when compared to the U.S. level.

• Methodology: The authors use the Hsieh and Klenow (2009) framework to measure resource misallocation. They calculate TFPQ (TFP in physical units) and TFPR (TFP in monetary value) and use these to estimate the efficiency gaps between firms and sectors.

• Data and Methodology Details:

  • The data is sourced from the Annual Industry and Services Statistics (AISS), covering firms with more than 20 employees from 2003 to 2014.
  • The dataset is cleaned and filtered through several steps to ensure accuracy and consistency, resulting in 181,052 observations in the final dataset.
  • The framework assumes that TFPR should be equalized across firms in the absence of distortions, and any deviation indicates misallocation.

• TFP Gains Over Time:

  • In 2003, the TFP gap from the U.S. due to misallocation was 56.1%.
  • By 2013, this gap had decreased to 18.4%.
  • However, in 2014, the gap increased to 24.5%, indicating a reversal in the trend of improvement.

• Distortions and Wedges:

  • The paper estimates capital and output wedges, which reflect the distortions in resource allocation.
  • These wedges show the degree of misallocation, with higher values indicating greater inefficiencies.

• Policy Implications:

  • The findings suggest that within-sector misallocation is a significant barrier to productivity growth.
  • Policy focus should shift towards improving competition policies and addressing political economy distortions, such as those affecting access to finance and regulatory environments.

Key Information

• TFPQ and TFPR are used to measure productivity in physical and monetary terms respectively.
• Capital and labor shares from the U.S. are used as benchmarks for the least distorted environment.
• TFP gains are calculated based on the assumption that equalizing marginal products across firms would lead to more efficient resource allocation.
• The analysis reveals that the textile, transport, food, and leather industries are the most affected by misallocation.
• Data cleaning is a crucial step, reducing the dataset from over 1.2 million observations to 181,052 after filtering and normalization.

Conclusion

The paper concludes that while Turkey has made progress in reducing resource misallocation in manufacturing, the trend has reversed in recent years. This suggests that addressing within-sector resource misallocation is essential for improving aggregate productivity and achieving sustainable economic growth. The findings highlight the importance of competition policies and political economy reforms in the context of Turkey's economic development.
