AI and Labor Productivity: A New Frontier for Workers
AI's Impact on Productivity: Evidence Reveals Positive Results
In today's fast-paced world, workers across industries are embracing AI, and one such tool making waves is the large language model (LLM) like ChatGPT. This technological marvel is reshaping professional tasks such as writing, coding, administrative work, text summarization, and research, offering empirical evidence of productivity enhancement.
Take writing, for instance. Noy and Zhang (2023) conducted a natural experiment, involving college-educated professionals completing writing tasks. Their research revealed that LLMs, including ChatGPT, boost writing productivity. Not only did the participants produce faster and higher-quality writing, but they also enjoyed their tasks more than those who didn't use ChatGPT. Interestingly, the benefits were more pronounced for those with weaker writing skills.
Moreover, Doshi and Hauser (2023) delved into the impact of LLMs on writing creativity. They discovered that access to AI-generated ideas enhanced the creativity of stories and quality of writing—as per a group of readers—particularly for weaker writers.
Meanwhile, ChatGPT has also proved its mettle in boosting coding productivity. Yilmaz and Yilmaz (2023) investigated the effect of programming education using ChatGPT on students' computational thinking skills, programming self-efficacy, and motivation. The findings were stark—students who used ChatGPT were significantly more effective coders, better computational thinkers, and more motivated.
On a broader scale, LLMs have shown benefits across various white-collar occupations. Brynjolfsson et al. (2023) examined generative AI's impact on customer support agents and found that it increased productivity by 14 percent on average, with the most significant improvements occurring for novice and low-skilled workers. Similarly, Dell'Acqua et al. (2023) found that consultants with access to GPT-4 completed tasks significantly faster and with higher quality than those without access.
Beyond these findings, LLMs may improve productivity in diverse office tasks, as suggested by a series of recent papers. In a randomized controlled trial, Microsoft economists found that workers given access to Copilot could complete tasks faster while maintaining accuracy. Edelman et al. (2023) conducted two controlled trials evaluating Copilot's impact, finding similar statistically significant improvements in efficiency.
While these findings are promising, it's essential to acknowledge the limitations and challenges that come with widespread AI adoption. Concerns about job displacement persist, but LLMs are often viewed as tools that complement human work, possibly creating new roles focusing on AI management and optimization.
To sum up, large language models like ChatGPT show great potential in enhancing productivity across professional tasks by automating routine work. Yet, the broader economic impact, including earnings and job displacement, remains a subject of ongoing research and debate. Policymakers should see these preliminary findings as a reason to continue supporting AI advancement and adoption, with the hope that it could trigger much-needed productivity growth, improving living standards globally.

Enrichment Data:
The emergent evidence on the impact of LLMs on productivity across various professional tasks offers a mixed picture of benefits and limitations.
Key Benefits:
- Automation and Time-saving: LLMs can automate repetitive tasks, allowing professionals to focus on higher-value work requiring creativity and critical thinking.
- Efficiency in Administrative Tasks: LLMs can efficiently handle routine administrative tasks, freeing up time for complex work.
- Code Completion and Writing: LLMs can speed up coding tasks with their code completion abilities and assist with content creation, editing, and proofreading in writing.
Enterprise Adoption and Impact:
- Wide Adoption: Over 2 million businesses worldwide have integrated ChatGPT into their workflows, indicating a shift from exploratory use to committed integration.
- Cost Savings: Companies are reporting substantial savings through the use of LLMs, with some saving over $75,000.
Limitations and Challenges:
- Earnings and Employment: Despite increased productivity, some studies suggest that LLMs have not significantly impacted earnings or hours worked across occupations.
- Job Displacement vs. Complementation: While concerns about job displacement linger, LLMs are often seen as tools that complement human work rather than replace it, possibly leading to the creation of new roles.
- The use of AI-generated ideas, such as those provided by large language models like ChatGPT, can enhance the creativity of stories and the quality of writing, particularly for weaker writers, as suggested by the research conducted by Doshi and Hauser (2023).
- In a study by Brynjolfsson et al. (2023), it was found that generative AI, including large language models, increased productivity by an average of 14 percent in customer support agents, with the most significant improvements occurring for novice and low-skilled workers.
- The impact of large language models (LLMs) on productivity across various white-collar occupations raises questions about the broader economic impact, including possible earnings and job displacement. Policymakers should continue supporting AI advancement and adoption, understanding that while LLMs may create new roles focusing on AI management and optimization, concerns about job displacement persist.
