En la década de los setenta se hicieron numerosos estudios para ver el poder de este principio de escasez y el efecto de la reactancia sobre las actitudes de los consumidores. Así West (1975) preguntó a un grupo de estudiantes qué opinaban de la cafetería del centro resultando la valoración no muy positiva. Un tiempo después se les comunica que la cafetería permanecería por obras cerrada durante un período y se les vuelve a preguntar nuevamente su opinión sobre ésta obteniendo una valoración global mucho más favorable que en la primera recogida de datos.
Well, charity: water took an alternate route. Once someone donates to a charity: water project, her money takes a long journey. Most charities don't tell you about that journey at all -- charity: water uses automated emails to show donors how their money is making an impact over time. With the project timeline and accompanying table, you don't even really need to read the email -- you know immediately where you are in the whole process so you can move onto other things in your inbox.

Let’s say you have a promotions page where you’re promoting a product via affiliate links. If you currently get 5,000 visits/month at a 2% conversion rate, you have 100 referrals. To get to 200 referrals, you can either focus on getting 5,000 more visitors, or simply increasing the conversion rate to 4%. Which sounds easier? Instead of spending months building domain authority with blogging and guest posts to get more organic traffic, you just have to increase the conversion rate by 2%. This can include landing page optimization, testing your calls-to-action, and having a conversion rate optimization strategy in place. By testing and optimizing your site, you’ll get far better results with much less effort.
In 2008 the state of New York passed a law asserting sales tax jurisdiction over Amazon.com sales to New York residents. New York was aware of Amazon affiliates operating within the state. In Quill Corp. v. North Dakota, the US Supreme Court ruled that the presence of independent sales representatives may allow a state to require sales tax collections. New York determined that affiliates are such independent sales representatives. The New York law became known as "Amazon's law" and was quickly emulated by other states[44]. While that was the first time states successfully addressed the internet tax gap, since 2018 states have been free to assert sales tax jurisdiction over sales to their residents regardless of the presence of retailer affiliates[45].
