The Surprising Geography of Vacation Homes in the US

An analysis of US Census data reveals fascinating patterns in the distribution of vacation homes across the country. Florida leads with over 800,000, followed by California and New York. However, as a percentage of total housing, New England states like Maine, Vermont, and New Hampshire boast the highest proportions, exceeding 15%. Vacation homes cluster heavily along coasts, near the Great Lakes, in New England, and parts of the West. Location correlates strongly with geographical amenities like beaches, lakes, mountains (and ski resorts), golf courses, and theme parks. Surprisingly, major cities have a disproportionately low percentage of vacation homes. The study also notes that vacation home growth lags behind overall economic growth, likely due to low construction productivity and restrictive zoning regulations.

Multiple Invention: It's Way More Common Than You Think

A study of 190 major inventions between 1800 and 1970 reveals that multiple invention—where the same invention is independently created by multiple individuals—is surprisingly common. Over half of the inventions examined involved multiple attempts, and nearly 40% had multiple successful or near-successful versions. This suggests that many inventions weren't unique strokes of genius, but rather stemmed from a confluence of readily available technologies, materials, and capabilities, combined with a shared focus on significant problems. This challenges the 'Great Man' theory of invention, suggesting that technological progress is more a product of broad historical forces.

US Navy Shipbuilding: A Case for Simpler Designs

US Navy shipbuilding is plagued by cost overruns and schedule delays. This policy proposal argues that this stems from the Navy's reliance on complex, multi-role ship designs and outsourced design processes. The authors recommend a return to simpler, single-purpose ship designs and in-house design capabilities to improve efficiency, reduce costs, and ultimately build more ships for less. Case studies of the Ford-class carrier, Burke-class destroyer, and Littoral Combat Ship illustrate the problems of complex designs. The proposal offers alternative, more cost-effective ship designs, focusing on streamlined capabilities and efficient production.

WWII: The Miracle and Bottleneck of US Shipbuilding

During WWII, the US shipbuilding industry achieved a miracle, constructing thousands of military and merchant vessels in just a few years, turning the tide of the war. This was due to massive government investment and effective management of private enterprise, and entrepreneurs like Henry Kaiser adopting novel construction techniques such as prefabrication and welding, dramatically increasing efficiency. However, even under the urgency of war, US shipbuilding efficiency remained far below other nations, and rapidly declined after the war, highlighting the long-term challenges of improving shipbuilding efficiency.

Why Did Skyscrapers Become Glass Boxes? Economics, Not Modernism

This article explores the shift in US skyscraper design from ornate brick and stone structures to the ubiquitous glass box. Contrary to the popular narrative of a modernist architectural conspiracy, the author argues that the driving force was economic efficiency. Glass curtain walls proved cheaper to construct, faster to erect, and offered greater rentable square footage. While tenants prioritize interior space, developers found that exterior ornamentation had little impact on rental prices, making cost-cutting a primary concern. Though some architects and developers still champion more expressive designs, the relentless pressure for profit maximization has solidified the glass box as the dominant aesthetic.
