UD GHM clarification
Hello EveryoneThere was a bit of confusion today regarding how to fit the upstream-downstream firm example we studied in class to to canonical GHM model. I may have implied that the former could not directly be fit to the framework of the latter. This is incorrect. The GHM model can accommodate this setting exactly, but you must be careful how you construct coalitional payoffs.
Consider the UD example. U's investment is made directly on
the asset. Therefore, under integration, after U's investment
is made, his cooperation is no longer needed for surplus to be
generated for the asset owner. In particular, we can specify
coalitional payoffs v(S,e) under integration as:
v({U,D},e)=Q(e)-R(e)
v({U},e)= Q(e)-R(e)
v({D},e)=0
From this you can see that U generates no additional marginal
surplus in any coalition, and therefore will recieve 0 via NB or
SHV.
However, note that this setting is inherently different from a
setting where, under integration, U's cooperation is still
necessary for the full coalition to generate surplus. In this case,
coalitional payoffs would be:
v({U,D},e)=Q(e)-R(e)
v({U},e)= 0
v({D},e)=0
In this case, U does generate marginal surplus in the full
coalition and will therefore recieve half of this surplus via NB or
SHV. This is the case that HM 90 and Gans 2005 focus on in their
papers and is why we observe that non-asset owners still extract
positive surplus ex post in those models.
You can think of the latter setting as the investment being like an investment in human capital. Even if you eventually use that human capital working on someone else's asset, they must cooperate with you to obtain the benefit from that investment. They cannot extract your human capital without your permission even if you have already invested in it.
I apologize for the confusion and i hope this helps. Please email me if you have questions
