Finally, Figure step 10 reveals this new overlap personality

It plots the change within the RA1’s means since level of attacks leftover develops. Reputation will get much less extremely important because amount of attacks leftover refuses because there are a lot fewer episodes to reap the pros off high character. Therefore, get inflation increases. Keep in mind that, as number of episodes leftover increases, the methods converges, implying that we approach an extended (infinite) views equilibrium.

Bottom line, our results demonstrate that initiating competition in the form of good second RA isn’t sufficient to punishment the newest RAs which usually rest which have positive chances during the harmony. We have now show that battle will in actuality enhance the lax actions regarding RAs and relieve expected interests.

5.step 3 Contrasting monopolistic and competitive RA

It is often recommended one to initiating alot more race regarding the reviews community is also relieve the dilemma of improper bonuses and get rising prices. Yet not, all of our performance show that race does become worse this case and you may end up in way more rating inflation.

We are able to see that industry-revealing impression dominates brand new disciplining perception (i

Figure 11 compares the strategic behaviour of RA1 under no competition, that is, monopolistic RA ( q2 = 0 ), and under a competitive setting with different values of q2 . We observe that in most cases, RA1 is prone to greater rating inflation relative to the monopolistic RA.

As described before, the implication of competition can be divided into the market-sharing effect and the disciplining effect. e., competition aggravates lax behaviour) in most cases. The only case where competition may actually alleviate the lax behaviour of RA1 is when q2 is very low (as shown in Figure 10). This is because the market-sharing effect is weakest relative to the disciplining effect for low values of q2 . Intuitively, the disciplining effect only depends on the difference between q1 and q2 ; whereas, the market-sharing effect increases with the absolute level of q2 . Hence, the market-sharing effect tends to dominate the disciplining effect except for low values of q2 .

As shown in Figure 12, the expected increase in lax behaviour of RA1 is always positive, indicating that competition will, in general, aggravate rating inflation. This is because a smaller market share will tend to reduce the reputational concerns of the RAs, and this market-sharing effect outweighs the disciplining effect brought by competition. Moreover, we can see that the expected increase in lax behaviour is increasing for low values of RA1’s own reputation and decreasing for high values of RA1’s reputation. The intuition is that, when the reputation of RA1 is low, the market share of RA1 is going to shrink significantly after introducing RA2 and the market-sharing effect of competition is strongest. However, when the reputation of RA1 is high, the impact of introducing RA2 on RA1’s market share is small, hence the market-sharing effect becomes weaker and RA1 will lie relatively less. We verify that the excess lax behaviour, as defined above, is always positive for other values of ? and pGrams in Appendix B.1, Figures 17 and 18.

Contour 13 measures up the complete hobbies between your monopolistic situation and you may the new duopolistic instance in which both RAs have the same profile. 21 21 We are calculating the newest passions in a single months merely whilst doesn’t believe time. We are able to observe that in the event the another RA are lead with a similar character since the incumbent RA, then overall appeal are often decrease, due to the fact that each other RAs will increase evaluations.

Moreover, when we compare in Figure 14, the expected total welfare between the monopolistic case and the duopolistic case with fixed values of reputations of RA2, we can see that introducing competition will always lead to lower total welfare as long as the reputation of RA2 is lower than the reputation of RA1. However, total welfare may increase if the entrant RA has a higher reputation than the incumbent. Overall, this implies that competition is likely to adversely impact total welfare, unless we can introduce a new RA with much higher reputation than the incumbent. We check the robustness of this result for different values of ? and pG in Appendix B.2.
