Final answer:
Hotels are using personalized recommendations and experiences as a nudge to compete with Airbnb.
Step-by-step explanation:
An example of a nudge that hotels are using to compete with Airbnb is offering personalized recommendations and experiences to their guests. This can be done through the use of technology and data analysis to understand the preferences and interests of their guests. For example, hotels can use guest data to recommend local attractions, restaurants, and activities that align with the guest's preferences. This personalized approach can provide a unique and tailored experience that Airbnb may not be able to replicate.
