So the previous video was all about structural entry barriers.
What they are and how they affect the attractiveness of entry.
This one is going to be about strategic entry barriers, so let's first have a
look at what they actually are and then see how they work economically.
So, remember entry barriers are factors that allow incumbent firms to earn
positive economic profits. So, it's something good to have an entry
barrier if you are an incumbent. While making it unprofitable for newcomers
to enter the industry, so, entrants, newcomers, will not want to
enter a market with high entry barriers, and leaving aside the structural entry
barriers which are basically entry barriers that are somehow part of the
nature of the industry, let's now focus on strategic entry barriers.
Strategic entry barriers are the result of conscious strategic actions,
aggressive strategic actions by the incumbent,
intended to keep the entrant out of the industry.
So, why would one do this and what could that be?
Well, an incumbent typically, when trying to deter entry, takes some costly action.
Right? This could mean overinvesting in
advertising or in branding, or making offers, making favorable long
term contracts to potential consumers. And these consumers will then find it
hard to sign up with an entrant. So, these are all entry deterring actions.
Why are they? Because they will make it more difficult,
they would make it less attractive for an entrant to come into a market.
Why would an incumbent do this? He would only do this if two conditions
are met. The first one is that the incumbent earns
higher profits despite deterring, by staying a monopolist rather than a
duopolist which let's another person, another player come into the market.
The second condition is that this entry deterrent strategy changes the
entrant's expectations about the nature of post-entry competition.
So in other words, entry deterrence has to be profitable, and it has to be
successful in keeping the other player out of the market.
So now assume that we have some kind of behavior, let's say signing people,
signing consumers up on long-term contracts.
Let's say over-investing in capacity, or in a brand, or something along those
lines. What does that do economically?
How does that play out? And when should we deter entry?
So let's say without any threat of entry, without anything happening, we make a
level of profits that's up here. So these are my monopoly profits.
After period 1, after t1, there could be entry, maybe because a patent is running
out, maybe because a license comes up for sale.
Maybe because technologoy develops in a way such that from t2 onwards
another player can come into the market. So I now have 2 things I could do, I have
2 options. The first one is to block entry, so that
means I overinvest in capacity, I sign up people on long term contracts,
I overinvest in marketing, okay. This means
I engage in some costly strategic action that lowers my profits compared to
monopoly profits but its successful in keeping the entrant out.
The other option is to accommodate entry, in which case I don't change anything
about my behavior in period one and then after period two I just accept that
someone is going to come into my market. So the level of profit is going to be
high early on, and then it drops because I become a duopolist.
I have a second player in the market. I have a competitor in the market.
So, there's two things we can think about.
One thing is that the difference between monopoly profits and the profits from
blocking entries is simply the cost of deterring entry.
The second is the difference between monopoly profits and the profits when
accommodating entry is the cost of losing market share.
Alright, so both things are costly. The differenc is here, that blocking entry
comes straight away and accommodating entry comes only after
the entrant enters the market. So when should we deter and when should
we accommodate? Well, if we think about it this way, if
we think about using this graph, very stylized one, of course.
But thinking about it using this graph, we simply have to compare
the net present value of these two objects.
Let's think of the net present value of accommodating entry.
So early on we make high profits, and then after the entrant comes in, we make
lower profits. Okay, so the net present value, we have to
discount profit payoffs that we get in the future, but this is basically the
area of profits for accommodating entry. Let's now have a look at the profits from
blocking entry. The net present value from blocking
entry. So here I make profits that are here all
the time. So that means that, the net present value
is going to be all this level of profits, all these profits.
So what you can see here, is basically two regimes, two parts.
Over here, it seems more attractive to accommodate entry, because you are not
changing your behavior, right. This is the cost of deterring entry.
On the other hand, over here, it's attractive to have blocked entry, because
there's a cost to loosing market share, as we have seen just now.
So, depending on how highly you evaluate the future you are going to want to
accommodate entry if your focus is on the present
or you would want to block entry if your focus is on the future.
So now we know how to choose a market. It depends on Porter's Five Forces, the
attractiveness of a market, and it depends on the degree of entry barriers
that there is in the market. The next step now is going to be to
figure out what the best way to enter a market is.
And this is what we'll discuss in the next videos.
So, thanks very much, and stay tuned.
