<p>In principle, there are two effects of merging companies that have opposite effects on welfare/efficiency:</p>

<p>A) A merger could result in more efficient production. This could be because the merged firm will adopt the practices of the most productive of the two original firms. Alternatively, it could be because of economies of scale. We think that many processes are more efficient if they are done on a bigger scale. The investment in designing a product and designing and installing a very efficient production process only pays off if you have a large enough scale. finally, it could even happen because it's efficient for a single entity to own the upstream and downstream processes in order to avoid negotiation costs and invest heavily in relationship-specific technology.</p>

<p>B) On the other hand, a merger could result in less competition. This could happen because the two companies were competing against each other and they are no longer doing so after the merger. It could also happen because the new larger firm is going to be a dominant player in input and output markets. It will be able to dictate terms to its suppliers, and also to its consumers, and even to its specialized employees.</p>

<p>The presence of these effects means that the work of anti-trust regulators is complex. They have to evaluate the likelihood on one of the effects being bigger than the other before the merger takes place in order to allow it or block it. Often what they do is to impose conditions on the merged entity in a way that guarantees that it will not be a dominant player.</p>

If you disagree with my statements, it's OK. I just needed to show the possible effects of merging big companies. Don't worry, I don't think any of it will ever happen :) I'm just interested what preventive laws are there to prevent it.

I think you need to be a little more specific. Is buying another company with the intent of shutting down its factories conspiracy if the plans are not secret or illegal? I think the conspiracy would be creating the legal environment which makes this possible, not the shutting down itself.

@denesp I'm not sure if I understand you well. It doesn't matter if it would be intentional or no (or if it would be evil conspiracy or friendly agreement). It seems for me, that for the biggest companies it is good to act this way.

# How do we prevent big companies conspiracy?

(Asked by: username_0 on 2016-03-04)

These days we can see a bunch of troubling trends.

* Consumer goods are less quality.
* Big companies merge.
* Patent laws and strict requirements on appearance remove small entrepreneurs from the manufacturing business.

These problems had been subjects of dystopian sci-fi scenarios for many times. Even though it is profitable for a starting bussinessman to buy and sell as the supply and demand dictates, for a few big companies, ruling over the market it is profitable to keep the prices up.

What can lawmakers do about concluding conspiratorial agreements or merging big companies to keep the supply and demand principle?
