Is Technological Progress Slowing Down? Yes, evidence from sectors like American agriculture suggests a slowdown in technological progress, particularly when comparing the periods of 1920-1970 and 1970-2020; however, pioneer-technology.com will explore the evidence, potential causes, and future implications of this trend, providing you with in-depth insights. Let’s delve into productivity paradox, innovation stagnation, and the future of technology.
1. Why Focus on Agriculture to Measure Technological Progress?
Agriculture offers valuable insights into long-term technological changes due to its data availability, technological dynamism, and consistent product measurement. By analyzing agricultural trends, we can gain a clearer understanding of whether technological advancement is indeed slowing down.
- Data Availability: Agriculture boasts extensive historical data.
- Technological Dynamism: The sector experiences continuous technological advancements.
- Consistent Product Measurement: Products like corn remain relatively unchanged over time, ensuring consistent measurement.
Annual Bushels of US Corn
Annual bushels of US corn demonstrate the sector’s long-term data availability and significant changes over time, measured consistently.
1.1 How Have Inputs Like Labor and Land Impacted Agricultural Output?
Agricultural output in the U.S. has significantly increased without substantial increases in labor and land use, highlighting the impact of technology. Land use has remained stable, while labor input has decreased dramatically. This suggests that technological advancements are primarily responsible for the upswing in production.
Agricultural Inputs: Labor and Land
Labor input in agriculture has fallen dramatically, while land use has remained stable, underscoring the impact of technology on increased output.
1.2 What Do Yield Measurements Reveal About Technological Progress?
Yield measurements, reflecting the efficiency of transforming land into output, indicate a slowdown in technological progress in agriculture. Although yield growth remains higher than pre-1940 levels, there has been a noticeable deceleration.
US Corn Yields and Growth Rate
Average U.S. corn yields show a slowdown in the rate of technological progress, indicating a deceleration in yield growth.
2. Measuring Technological Progress Beyond Yields
While yields provide a simple metric, a comprehensive assessment requires considering all agricultural inputs and outputs to account for complexities like climate and pest environments. This approach involves using total factor productivity (TFP) to provide a more accurate understanding of technological progress.
2.1 How Is Total Factor Productivity (TFP) Calculated?
Total Factor Productivity (TFP) is calculated by dividing an index of all outputs by an index of all inputs, adjusted for quality and changing input mixes. This measure provides a comprehensive view of agricultural efficiency. Economic theory provides a framework for constructing these estimates, using weighted indices based on the share of total costs.
2.2 What Do TFP Estimates From USDA and InSTEPP Indicate?
TFP estimates from the USDA and InSTEPP indicate a slowdown in agricultural productivity growth, aligning with broader trends in the U.S. economy. While there are methodological differences, both sources converge on the conclusion of decelerating growth.
| Factor | USDA | InSTEPP |
|---|---|---|
| Data Range | Through 2017 | Through 2007 |
| Output Trends | Agrees on output produced by the U.S. farm sector | Agrees on the amount of labor used |
| Input Trends | Disagrees more on the use of land | Differs significantly in the measurement of capital inputs, such as tractors and durable goods |
| TFP Growth Rate | Shows declines beginning in the 2000s | Shows declines beginning in the 1990s |
| Overall | TFP growth in agriculture has indeed slowed | TFP growth in agriculture has indeed slowed |
TFP Growth Rate in US Agriculture and Economy
The twenty-year growth rate of TFP in U.S. agriculture and the U.S. economy shows a decline, indicating a slowdown in productivity growth.
3. The Impact of Natural Factors on Agricultural Productivity
Natural factors, such as weather, CO2 levels, and pests, significantly influence agricultural productivity. Understanding these factors is crucial to accurately assess technological progress. While worsening weather doesn’t fully explain the slowdown in yield or TFP growth, it does exert a powerful influence on agriculture.
3.1 How Does Weather Affect Agricultural TFP?
Research indicates that while weather impacts annual fluctuations in TFP, it does not fully explain the long-term slowdown in agricultural productivity. Studies by Liang et al. (2017), Chambers and Pieralli (2020), and Plastina, Lence, and Ortiz-Bobea (2021) suggest that weather-related effects tend to offset each other at the national level, exerting only a minor drag on TFP growth.
3.2 What Role Does CO2 Play in Crop Yields?
Rising atmospheric CO2 levels have been shown to potentially augment crop yields, though the magnitude of this effect is debated. Taylor and Schlenker (2021) suggest that CO2 may account for a significant portion of corn and wheat yield improvements.
3.3 How Do Biological Pests Influence Agricultural Production?
Biological pests, including diseases, weeds, and insects, can reduce agricultural output and necessitate increased input use. Increased herbicide resistance, for example, has led to a rise in herbicide use since 2010 (Hellerstein et al. 2019).
4. Potential Reasons for Slowing Technological Progress
The stagnation in agricultural R&D from 1980 to 2007 and the broader economic trends may explain the slowdown in technological progress in agriculture. Further research is needed to fully understand these dynamics.
4.1 How Has Stagnant Agricultural R&D Impacted Innovation?
A constant level of R&D effort tends to result in smaller gains in innovation. The lag between basic science and technological application is often around twenty years, which could explain the productivity growth slowdown observed.
Agricultural Research and Development Funding
Agricultural R&D funding data shows a stagnation from roughly 1980 to 2007, which may have contributed to the slowdown in technological progress.
4.2 Is There an Echo Effect From the Wider US Economy?
There appears to be an echo effect where productivity changes in the non-farm economy precede similar changes in agriculture. Alston and Pardey (2021) estimate that upswings in the non-farm economy are followed by upswings in the farm economy a few decades later.
4.3 How Does Knowledge Spillover Affect Agricultural Innovation?
Patented agricultural technologies rely heavily on ideas and knowledge developed outside of agriculture. Clancy, Heisey, Ji, and Moschini (2021) demonstrated that many agricultural technology patents are more likely to cite non-agricultural patents and journals.
Knowledge Spillovers in Agricultural Innovation
Adapted from Clancy, Heisey, Ji, and Moschini (2021), this shows that patented agricultural technologies rely heavily on ideas and knowledge developed outside of agriculture.
5. Addressing the Broader Slowdown in Technological Progress
The slowdown in agriculture may reflect a broader trend in technological progress, influenced by factors like urbanization and the reorganization needed to implement new technologies.
5.1 How Does Urbanization Affect Innovation and Diffusion?
Innovation tends to emerge in cities and diffuse slowly to rural areas like agriculture. This diffusion lag can contribute to the delayed impact of technological advancements in agriculture.
5.2 Why Is Reorganization Important for Technological Adoption?
Economic reorganization is necessary to fully realize the benefits of new technologies. For example, if technology favors larger farms, there will be a period of farm consolidation. This process can be slow in agriculture due to its deep roots in family, culture, and place.
6. The State of Innovation in Agriculture
Examining adoption rates of various technologies in agriculture can further illuminate the dynamics of technological progress.
