The “Bet” refers to a wager made between Julian Simon, an economist, and Paul Ehrlich, a biologist, about whether the prices of five metals—tungsten, copper, chromium, nickel, and tin—would rise or fall over the course of a decade. Simon believed that resource prices would decline due to technological advancements, while Ehrlich believed they would rise due to scarcity and environmental pressures. The bet lasted from 1980 to 1990, and the results of this bet are often used to examine the validity of both viewpoints.
The issue in the Bet is whether human ingenuity (as represented by Julian Simon) or resource scarcity (as represented by Paul Ehrlich) would determine the prices of natural resources in the long run. The outcome of the Bet has broader implications for how we think about the sustainability of natural resources and economic growth.
Bet Setup: In 1980, Simon selected five metals and agreed to a bet with Ehrlich. The bet was for $1,000, with Simon betting that the prices of these metals would decline over ten years (from 1980 to 1990), while Ehrlich bet that the prices would increase.
Simple Real Price Index (SRPI): This index compares the prices of the five metals adjusted for inflation over time. The formula for the SRPI is:
\[ SRPI_t = \frac{\text{Nominal Price of Metal at Time t}}{\text{CPI (Consumer Price Index) at Time t}} \times 100 \]
The SRPI adjusts the nominal prices of the metals by the rate of inflation, allowing for a clearer comparison of real price changes.

dyRangeSelector()To calculate and plot the Simple Real Price Index in R, you’ll first need to gather the historical data for each metal’s price and the Consumer Price Index (CPI) over the years of the Bet (1980-1990). Here’s how you can implement this in R:
Then: The Bet focused on the debate between Julian Simon and Paul Ehrlich on whether human ingenuity or resource scarcity would determine the prices of natural resources. The Bet was concluded in 1990, with Simon’s argument winning as the prices of the metals decreased or remained stable, adjusted for inflation.
Now: The relevance of this debate is still crucial in today’s discussions on sustainability, resource management, and environmental conservation. Although there are more environmental concerns about depletion of resources, the role of technological innovation (such as in renewable energy or resource recycling) continues to play a significant role in ensuring the sustainability of resources.
In light of the Bet’s results, where Simon’s optimism about human ingenuity prevailed, the emphasis for future U.S. government policy should be on fostering innovation, investing in renewable technologies, and encouraging sustainable resource use. This approach, paired with responsible environmental practices, would likely ensure that future generations benefit from both economic growth and environmental sustainability.
The government should also focus on the following: - Investing in Technology: Encourage innovation in alternative resources and recycling technologies. - Addressing Climate Change: While resource prices might not always rise, the environmental cost of extracting and using them should be a major consideration. - Global Cooperation: Work with other nations to ensure equitable distribution and responsible management of natural resources.
