Thinking Strategically

Slide 2

The crimped request bend model of Oligopoly Assume no participation or agreement among firms This model clarifies why the costs in some oligopolistic markets change gradually after some time – singular firms are essentially hesitant to change value as a result of what different firms may do.

Slide 3

Kinked Demand Curve Assume that we have 3 firms: A, B, & C Products are comparative The state of the request bend for An's item reveals to us the amount QD changes when there is a value change (versatility) – this relies on upon the estimating conduct and likeness of the substitutes B and C.

Slide 4

Kinked Demand Curve Consider what happens when A progressions its value: 1. On the off chance that firm A brings down value then B and C can take after the value change or disregard it. On the off chance that B and C take after then they additionally bring down cost since they fear losing their piece of the pie to firm A. In the event that B and C overlook the value change by A, then they keep up the higher cost since they don't trust that individuals will switch. 2. On the off chance that firm A raises value then B and C can take after the value change or disregard it. In the event that B and C take after then they likewise raise cost since they don't trust that individuals will switch, so they can expand benefits by additionally charging more. On the off chance that B and C disregard the value change by A, then they keep up the lower cost since they trust that individuals will switch, and they can catch some of firm A's piece of the overall industry by having a lower cost.

Slide 5

Kinked Demand Curve Notice that if the contenders B and C disregard the value change – then we have more value distinction than some time recently, so buyers will probably switch between items. In the event that A brings down cost and B and C don't take after : shoppers will probably substitute toward A lessening in the Price of A => huge increment in QD for A So if A raises cost and B and C don't take after : buyers will probably substitute toward B and C increment in the Price of A => enormous reduction in QD for An If alternate firms don't take after then the interest for An's item will be generally ELASTIC (level incline).

Slide 6

Kinked Demand Curve On the other hand, if alternate firms do take after A's value changes, then there will be less substitution occurring and the interest for An's item will be moderately INELASTIC (soak incline).

Slide 7

Kinked Demand Curve Now… Pretend that you are firms B and C and I am firm A. Also, you imagine that your item is a nearby substitute for my item. What will you do in the event that I raise cost? Nothing. Keep your value low to attempt and catch my piece of the overall industry. You don't take after => this makes my request ELASTIC (level) over the present cost. What will you do on the off chance that I bring down cost? Take after and furthermore bring down value with the goal that I don't catch your piece of the pie. This makes my request INELASTIC (soak) underneath the present cost

Slide 8

Kinked Demand Curve When firms trust that their item is a nearby substitute for their rival's item, they don't have much motivating force to change value: A value reduction will be coordinated , so they don't have anything to pick up by bringing down cost. A cost increment won't be coordinated , so they have a considerable measure to lose by raising cost.

Slide 9

Theory of Games The result of many activities relies on the activities of others For instance, a defectively focused firm should measure the reactions of opponents when choosing whether to cut their costs The choices of contending firms are regularly associated

Slide 10

Game hypothesis A scientific procedure for investigating the choices of related oligopolistic firms in unverifiable circumstances. A "diversion" is just a focused circumstance where at least two firms or people seek after their interests and no individual can direct the ultimate result or "result". Players pick their methodology without certain information of alternate players techniques, however may in the long run realize which way the resistance is inclining.

Slide 11

Elements of a Game Basic components The players The procedures The adjustments Payoff network The essential instrument of amusement hypothesis. This is basically a method for arranging the potential results of a given diversion in a table that portrays the adjustments in an amusement for every conceivable mix of systems

Slide 12

Strategies Dominant procedure A methodology that yields a higher result regardless of what alternate players in an amusement pick Dominated technique Any other methodology accessible to a player who has a predominant technique Nash Equilibrium Any blend of methodologies in which every player's technique is his best decision, given the other players' systems IOW: Nash balance is accomplished when all players are playing their best methodology given what alternate players are doing.

Slide 13

A straightforward diversion and result grid Duopoly circumstance – each of the two firms An and B must choose whether to mount a costly publicizing effort. On the off chance that each firm chooses not to publicize, each will acquire a benefit of $50,000. On the off chance that one firm promotes and alternate does not, the firm that wills increment its benefits by half to $75,000, and drive the opposition into a misfortune. On the off chance that both firms promote, they will acquire $10,000 each in light of the fact that the publicizing cost constrained by rivalry wipes out huge benefits

Slide 14

Example proceeded… If firms could consent to conspire, the ideal system would clearly be to not publicize – expand joint benefits = $100,000 Let's accept they can't plot, and thusly don't realize what the opposition is doing. A "Prevailing Strategy" is the one that is best regardless of what the resistance does.

Slide 15

The Payoff Matrix Firm B Don't Advertise Don't Advertise Firm A Advertise A benefit = $50 B benefit = $50 A misfortune = $25 B benefit = $75 A benefit = $75 B misfortune = $25 A benefit = $10 B benefit = $10

Slide 16

New Game: "The Prisoner's Dilemma" You and your companion Bugsy are the prime suspects for thumping over an alcohol store. The cops lift you up, and promptly after your capture you and Bugsy are isolated and addressed independently by the DA. Without an admission, the DA has deficient confirmation for a conviction. Amid your cross examination, you are told the accompanying : The police do have adequate proof to convict you and Bugsy of a lesser wrongdoing. On the off chance that you and Bugsy both admit to the alcohol store heist, you will each get a 5 year sentence. In the event that neither of you admits , you will each be accused of the lesser wrongdoing, and sent up the waterway for 1 year. In the event that Bugsy admits (turns state's confirmation) and you don't , Bugsy will go free while you will be indicted the alcohol store burglary and get sent to the huge house for a long time. Bugsy is told precisely the same. What will you do?

Slide 17

The Payoff Matrix You Don't Confess Don't Confess Bugsy Confess Bugsy = 1 year You = 1 year Bugsy =7 years You = Free Bugsy = Free You = 7 years Bugsy =5 years You = 5 years

Slide 18

Prisoner's Dilemma Prisoner's Dilemma Each player has a predominant procedure It brings about settlements that are littler than if each had played a commanded system Produces struggle between slender self-enthusiasm of people and the more extensive enthusiasm of bigger groups

Slide 19

Naturalist utilizations of detainee's predicament Why do individuals yell at gatherings? Why does everybody stand up at shows?

Slide 20

There are a few recreations where one player does not have an overwhelming methodology but rather the result is unsurprising … A Left Right Top B Bottom A's conduct is unsurprising for this situation. B benefit = 100 A benefit = 0 B benefit = 100 A benefit = 100 B misfortune = 100 A benefit = 0 B benefit = 200 A benefit = 100

Slide 21

One more … A Left Right Top B Bottom Here, A's conduct is again unsurprising – pick Right is the prevailing procedure – however now B stands to lose an incredible arrangement if by chance A picks left rather B benefit = 100 A benefit = 0 B benefit = 100 A benefit = 100 B misfortune = 10,000 A benefit = 0 B benefit = 200 A benefit = 100

Slide 22

Cartels Cartel A gathering of firms who offer a comparable item who have combined in a consent to go about as a restraining infrastructure – confine yield and raise value Normally cartels include a few firms Make countering against a protester troublesome Agreements are not lawfully enforceable and are henceforth inalienably temperamental

Slide 23

Reasons for conspiracy among firms to decrease the vulnerability of a noncooperative circumstance – rivalry over piece of the overall industry makes firms uncertain of what to do concerning evaluating choices – they're hesitant to change costs – so to maintain a strategic distance from the likelihood of a value war, firms may attempt to collaborate. to build benefits – this requirement for benefit can end up being the ruin of most cartels – GREED

Slide 24

Collusion Overt intrigue is illicit in the US. Most cartels come up short. This is on the grounds that 3 things are required for a cartel to be effective, and they're hard to achieve – first, the organizations must go to an understanding in the matter of what the cost and amount ought to be –tough to do in light of the fact that diverse firms will have distinctive cost structures and distinctive appraisals of market request, so what is the benefit amplifying cost and amount for one firm is not prone to be the benefit expanding mix for another firm. second, the cartel individuals must cling to the settled upon cost and generation levels – no bamboozling. However, each firm realizes that in the event that it cheats and the others don't, that they can have higher benefits. third, there must be the potential for imposing business model power – the market request bend must be generally inelastic so that there are potential ga
