企业为何要合作 Why Firms Work Together

根据经济学理论，企业会在市场上相互竞争。实际上，他们也常常进行友好合作。在本模块中，我们将尝试了解为什么合作会给相关企业带来好处，借此评估促进或阻碍合作的因素并将其应用到不同示例中。

So welcome back.

In our first lecture we've learned how to find optimal decisions in a strategic

game. These decisions often maximize our own

profits but they harm the competitor at the same time.

So in this video, I will introduce you to situations in which companies are

actually better off by cooperating with each other.

And why would firms want to cooperate in the first place.

Sometimes, quite simply, competition is not in the company's best interest.

Remember the last session. We had Sensodyne and Colgate deciding to

advertise or not to advertise. We found that the Nash Equilibrium in

such a game is for both firms to advertise, even though both knew that

they could be better off if they agreed not to advertise.

But each of the players, Sensodyne and Colgate, has an individual incentive to

actually not stick to that agreement and advertise anyway.

So the Nash Equilibrium here is an outcome that's not efficient

and it doesn't maximize both players profits.

So that's one situation in which cooperation can actually be a good thing.

Another situation is that, sometimes companies simply need each other.

And we recall the example that we discussed the last time, where Sony and

Philips had to agree on a standard for the compact disc.

And there were two standards available. There was the Sony standard and the

Philips standard, and both of them wanted to coordinate on one of those two.

But it wasn't clear if they were going to settle on this one, or on that one.

And they needed the cooperative behavior or the coordination between

these two players to settle on one of those.

So, in these situations cooperation can help avoid inefficient solutions.

So in this session, we're going to deal with a question or the problem of how to

achieve cooperation between individual profit maximizers.

The mechanisms we're going to take a closer look at are, repeated games.

So we play a prisoner's dilemma not just a single time, but a repeated number of

times. And we'll look at commitment, where we

can settle on a course of action before the other firm has done it.

We've just learned that companies that face a prisoner's dilemma or play a

coordination game, are often better off if they cooperate with each other or,

somehow, can coordinate their behavior. Now, this sounds simple in theory, but

it's hard to sustain given that our firms are selfish, individual, profit

maximizers. So if games are played repeatedly or

players commit to certain strategies, this can help enabling cooperation.

So in the following videos, we'll have a closer look at these mechanisms.

So stay tuned and see you in a second.
