About this website
Disclosures & Educational Use
A clear understanding of what this material offers.
Educational information
This website, its papers, case studies and videos explore the ideas in The Invisible Economy, Infrastructure Literacy and Applied Infrastructure Literacy. They provide general education and commentary, not advice tailored to a particular person, business, bank or transaction.
Nothing on this site constitutes individualized financial, investment, legal, tax, accounting or regulatory advice. Consult appropriately qualified professionals who can assess your circumstances and the applicable requirements before acting. Reading this site or contacting the author does not, by itself, create a client, advisory or fiduciary relationship.
Sources, examples and results
Documented case studies identify their sources. Illustrative examples are intended to explain a concept and should not be read as verified accounts of a particular person or organization. References to companies, platforms or public agencies do not imply their endorsement of the author, this website or the book.
Information reflects the dates and scope stated in each piece. Facts, laws, market conditions and platform policies can change. Check current original sources before making a decision. Interpretations and opinions are the author’s unless otherwise attributed; accuracy, completeness and continuing currency are not guaranteed. Examples, frameworks and past outcomes do not promise future earnings, business performance, regulatory approval or other results.
Discussion of banking, capital or investments is educational and is not an offer to sell, or a solicitation to buy, a security or financial product.
Book promotion and financial interest
Jeffery A. Garfield is the author of The Invisible Economy and publishes under Jeffery A. Garfield Publishing. This website promotes his work, and he earns royalties from book sales. Links to Amazon take you to the retailer for availability, pricing, payment, delivery and returns.
External websites
Social profiles, source citations and retailer links lead to independently operated websites. Their content, availability, privacy practices and terms are controlled by those providers. Review their terms before submitting personal information or completing a transaction.
Website analytics and your choices
With your permission, this website uses Google Analytics to understand visits, referral sources, pages read, scrolling, outbound links and selected interactions such as starting-path choices, book-link clicks, downloads, video playback progress and completed learning exercises. Google may receive page addresses, browser and device information, approximate location and cookie identifiers. This helps Jeffery understand which educational material readers find useful.
Analytics is optional. The Google Analytics tag loads only after you choose “Allow analytics.” Choosing “No thanks” leaves analytics off and does not restrict the website. Use Analytics preferences in the footer to change your choice. Your choice is stored in this browser for up to 180 days; clearing browser storage may reset it. When you withdraw permission, this site stops its Analytics collection and clears its Analytics cookies. Previously collected data is not erased by that choice.
Advertising personalization and Google Signals are disabled in this website’s tracking configuration. The site does not send names, email addresses or the answers from the decision exercise through its custom events. Book-link clicks indicate interest; they do not confirm an Amazon purchase. Purchases occur on Amazon and are governed by Amazon’s practices. Browser protections, blockers and visitor choices mean these reports do not count every visit.
Google’s processing is described in its Privacy Policy and its explanation of how Google uses information from sites that use its services.
