The homework is on bargaining. Note that M&R have a discussion of bargaining in Chapter 5. You should read that. The model they go through has both the buyer and seller having two types. In the Excel homework, the model has a continuum of type on each side of the bargain. In that sense it is harder but also more elegant. And, I believe, it should give you a better understanding about the relationship between the private information and the inefficiency created.
There is a fiction in the model that helps to understand what is going on. The fiction is that there is a third party - an arbitrator - who provides rules for how the bargaining will happen, when trade will occur, and at what price. The fiction is necessary because the model is static. Real world negotiations happen over time and to model that correctly one needs a dynamic model. There are such models, but they are well beyond the scope of our class. So we will keep the modeling relatively simple and wave our hands about what happens in real world bargaining.
There is a rather extensive discussion in this homework before you log in. I encourage you to read that carefully and not gloss over it. It is about how to bargain well and what happens in real-world procurement, which entails a good deal of such bargaining. There are practical lessons here that you can carry over to your work life, even if you don't engage in procurement.
Professor Arvan! This post does not have a label attached to it. Perhaps it would be better if this post is labeled with excel homework. Thank you :)
ReplyDeleteThanks! Just the type of mistake I'm prone to commit. I fixed it now.
