It plots the alteration into the RA1’s means because the level of periods leftover increases. Profile will get less and less important once the amount of attacks remaining refuses since there are a lot fewer periods so you can enjoy the advantages from high character. Thus, get rising cost of living expands. Keep in mind that, while the number of periods remaining grows, the techniques converges, implying that we strategy a long (infinite) opinions harmony.
The bottom line is, the show show that initiating race in the way of a dosnd RA is not enough to punishment new RAs and this usually sit that have self-confident possibilities for the harmony. We now demonstrate that race will actually enhance the lax conduct from RAs and reduce expected interests.

This has been suggested that releasing more battle in the studies world normally alleviate the dilemma of improper incentives and score rising cost of living. Yet not, the efficiency demonstrate that competition does get worse this case and you may end up in way more get rising cost of living.
We could observe that the market-sharing impact reigns over the brand new disciplining impression (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 full welfare between your monopolistic situation and you will the new duopolistic circumstances where both RAs have the same character. 21 21 We’re measuring the fresh new appeal in a single period only because cannot confidence day. We can notice that if a different RA is actually put with an identical profile since the incumbent RA, then your full passion will always be fall off, due to the fact that one another RAs will inflate analysis.
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.
