Construction Externalities Explained | Noise, Pollution & Environmental Valuation

Who pays when construction noise disturbs residents or dust increases a shopkeeper’s cleaning expenses? This video explains construction externalities and environmental valuation through simple illustrated examples. Follow a construction project’s effects on neighbouring homes, a roadside shop and a pond. Understand revealed preference through housing choices and stated preference through survey responses. Explore avoided damage using reduced cleaning expenses, and replacement cost through restoring water filtration. Learn why money spent on pollution control does not automatically equal environmental damage. The video separates mitigation expenditure from losses prevented and damage remaining. Designed for construction management students and beginners studying social cost-benefit analysis. No prior economics knowledge is required. Numerical examples illustrate concepts rather than actual project findings.
