challenges of reputation in the sharing economy
DESCRIPTION
We increasingly do more transactions with strangers, but how can we trust them? In the past, we always had a third party, a friend, to introduce us. This is no longer true in many cases, from online dating to sharing cars, we are now making decisions based on the reviews of other people who we do not know either. There are a significant amount of challenges to overcome over the next few years to create a world where we can trust one another. This presentation was first introduced at TheConference.se in Malmo, Sweden, in 2014, by Juan Cartagena, founder of traity.comTRANSCRIPT

Close Network
In a close network, everybody knows everybody else. If one player defects on another player, the rest of players will sooner or later learn about this and will take the bad player off the network. For example, in a network of Friends.
@JC2GOFirst Concept: Close networks vs Open networks

Open NetworkIn open networks, the links between people might not be shared with other people in their own network. In this case, if Red defects on Blue, Red still keeps her network of friends intact, as they will not learn about what happened to Blue. !Think buying and selling second hand from a stranger. If you get a lemon car, your friends will know, but he will not be affected.

Reputation in the past@JC2GO
In the past, we lived in the same town for many years, selling the same cheese to the same people. If we sold bad cheese today, people would find out quickly and stop buying at your shop. Reputation was built with every transaction, every day, over years, from fathers to sons.

Open Networks: Reputable Third Parties
@JC2GO
When town became bigger, we could not know everyone, so we had to start to trust brands, as a proxy for people. !You trust a consultant for the firm McKinsey. You trust a lawyer if his previous customer was Apple. You trust a doctor if she studied at Harvard. And you trust a new customer if she pays with Visa, because Visa covers the transaction, regardless.

So we have 2 dimensions for reputation

Endorsement
Previous History
Business Repetition = Low Risk
But you cannot extrapolate to other things. Good selling cheese does not mean good
driving cars.
The Unknown. !
Little to lose because noone will find out = High Risk
Reputation of the community. Brand extension from the institution to the
person. !
A lot to lose if you are expelled from the network = Low risk
High business repetition. High community interaction.
!Low risk, low friction.
Big Transactions. Intimacy.
Insurance Relationships

We already do all sorts of transactions with strangers.

Importance of Reputation@JC2GO
The value of the asset and the personal interaction leads the importance of reputation, for both endorsement and history.

With more transactions happening between strangers… !
How do we avoid irregularities to maintain social control?

Recommendations from weak links, even for other contexts like house sharing or car sharing, can help Blue to make a better decision about interacting with Red

As reputation becomes important for all our transactions…
… What will the role of Reputation in our society be?
@JC2GO

- Dividends to yourself? - Benefit in giving other people reputation?
Risk to yourself for giving it to the wrong person - Liabilities? Negative reputation? E.g.: People on LinkedIn only give
positive reviews. No incentive to jeopardize a relationship.
“Currency… because it is the oil of collaboration economy”
“Asset… because it is an important part of our personal value”
- Can be exchanged freely and has the same value everywhere - When I give you a dollar, I lose a dollar. Not with reputation… - Is there a limit to Inflation? (I give you a point, you give back) - Cannot everyone be rich in reputation? - Dollars from different people may have different value?

Reputation = Risk Premium
In my opinion…
- helps make better purchase decisions and whether transaction will take place at all
- Helps to choose between different options at different benefits and risks levels. Higher reputation might lead to higher prices and more safety of mind. More elastic people are more likely to accept lower reputation or lower level of safety.
- The risk can be reduced with more data

Challenges and unsolved debates for the next 10 years
Who owns your reputation? !
!
Right to forget? Right to delete? !
!
!
!
The value of negative reputation is High.
today your eBay stars only work within eBay.
If we delete all the negative stuff, reputation is worthless. But we might need to reduce the negative value of negative reputation of old stuff or even delete it after X years.
If you have 47 positive reviews on eBay and 1 bad one, people will go to read the bad one. Negative reputation data is critical for decision making.

Challenges and unsolved debates for the next 10 years!
Reputation of criminals who trust each other !
!
!
People left out - Offline to Online reputation !
!
!
Letting algorithms determine reputation. Inhumane?
Criminals trusting each other can lead to positive profiles.Need to be careful to measure the diversity of reputation.
My mother does not have ebay or AirBnB. But she has a good reputation. How do we make sure that people are not left out of opportunities?
If Algorithms run the show, perverse incentives. If humans need to read all the data of millions of transactions, they will make bad decisions.We need the right mix of complementarity to make right decisions. But how much?
