Pace of Technological Progress Illustrated by Lighting
The history of lighting illustrates the variable pace of technological progress. For much of human history, advancements were minimal, with early forms of light being as basic as campfires. By the early 1800s, progress was still slow; tallow candles, for instance, were only about nine times more efficient in light production per hour of labor compared to ancient animal fat lamps. In stark contrast, the pace of innovation accelerated dramatically with modern technology. The introduction of compact fluorescent bulbs in 1992 represented a massive leap, being approximately 45,000 times more efficient than the lighting technologies available 200 years prior.

Patterns of Technological Progress
Consider two technological developments in a historical context. The first is the creation of a new candle-making process that reduces the labor time required by 10%. The second is the invention of a system that allows a message to be sent across a continent in one day, where it previously took two weeks. Which of the following statements provides the best analysis of these two developments as measures of progress?
An economic historian is studying the efficiency of two different production processes over a 200-year period.
- Process A (Cloth Weaving): The time to produce one bolt of cloth decreased by a consistent 5% every 20 years for the entire 200-year period.
- Process B (Data Transmission): The time to transmit a 100-word message across a continent remained virtually unchanged for the first 150 years, then decreased by 99.9% over the final 50 years.
Based on this information, what is the most accurate conclusion about the nature of the progress observed in these two processes?

How has technological progress in lighting impacted the efficiency of light production over time?
Which of the following statements best describes the impact of compact fluorescent bulbs introduced in 1992 on lighting efficiency?
What was the primary measure of progress in lighting technology throughout history?
Which of the following best explains the significance of technological progress in lighting on living standards?
The rate of improvement in lighting efficiency between ancient times and the early 1800s was comparable to the rate of improvement between the early 1800s and the late 20th century.
The efficiency of lighting, measured in output per hour of labor, improved by a factor of approximately nine between ancient times and the early 1800s. In contrast, between the early 1800s and the early 1990s, it improved by a factor of approximately 45,000. What does this comparison primarily illustrate about the nature of technological progress?
An economist observes that for centuries, the efficiency of a particular production process improved by only 1-2% per century. Then, within a single decade, a series of new inventions increased the process's efficiency by 50,000%. Which of the following statements best characterizes the nature of the progress observed?
Analyzing the Pace of Innovation
The history of lighting, with its long period of slow improvement followed by a dramatic acceleration in efficiency, is often used as an example of how technological progress occurs. Which of the following statements presents the most significant critique or limitation of using this specific historical example as a universal model for all types of technological advancement?
