In this episode, we first travel more than 100 years to the city of Delhi, in India. 

The British colonial government decided to eliminate the overpopulation of cobras slithering around and put a bounty on each of them. The economic incentive initially worked well. However, the authorities did not foresee other subsequent events... Based on this story, in 2002, the German economist Horst Siebert coined the term “cobra effect” to describe cases of unintended consequences when the proposed solution backfires, making the problem worse. Hence, the title of this podcast! 

Today, we will also discuss two other cases of "cobra effects" in Vietnam and Brazil related to rats. 

These examples illustrate how unintended consequences transform good intentions into bad policies. From ancient Mesopotamia to current world events, The Cobra Effect Podcast explores the unintended consequences of government policies, including taxation, price and wage controls, foreign aid, collectivization, environmental issues, and more. Four millennia of history on all continents demonstrate that we repeat the mistakes of the past when judging ideas by intentions rather than results.
