reputation. According to Professor Dolnicar at UQ Business School, “this system rewards good host and good guest behavior and punishes bad host and bad guest behavior. Again, this is radically different than anything else in the traditional accommodation market. This is not helpful for improvement. In peer-to-peer networks guest feedback is more detailed. As such it enables hosts to continuously improve.” Meanwhile, the real constructive reviews are being ignore and underestimated by Airbnb. I think Airbnb staffs should pay more attention to the review and contact the reviewers to clarify the issues and take an action if necessary.b. Loyalty Program: Airbnb only charge a small transaction fee as the service between hosts and guess for every booking, but Airbnb doesn’t offer a promotion for loyal hosts and guests. I think Airbnb should follow the concept of hotels.com like offer 1 night free after 10 booking night or offers hosts service discount after certain period, etc. I believe Airbnb would gain more loyalty users in the future if they’re apply that concept into their current business.c. The safety and security of hosts and guests-this is difficult issues and can’t be easily resolve from both side. Guests might experience some issues like theft, destruction of property or even kidnapping, and they’ll pick the hotels in the future for safety purpose. Hosts, on the other hand, might expose themselves to legal and financial problem from accommodating guests, for instance, rooms and home being damage by huge parties. Airbnb should offer more information of its hosts within the city to the guests before their travelling so they’ll more options to choose from. For the hosts, Airbnb should work with insurance company to form more comprehensive plan that would shift the risk away from the hosts.
