Term
Competitors
Definition
If one firm's stratgic choice adversely affects the performance of another
Term
Can a firm have competitors in other markets?
Definition
Yes- in input or output markets
Term
Indirect competition
Definition
when the strategic choices of one firms affect the performance of another but only through the strategic choices of a third firm
Term
direct competitor
Definition
strategic choice of one firm directly affects the performance of the other
Term
Details of SSNIP
Definition
A small but significant nontransitory incresae in price. Small is at least 5% and nontransitory is at least 1 year
Term
difficulties of SSNIP
Definition
A merger shouldn't be necessary to identify competitors. It just proves that A&B are substitutes
Term
details of substitutes
Definition
1) They have the same or similar product performance characteristics. Product’s performance describes what it does for consumers.
2) They have the same or similar occasions for use- describes when, where and how it’s used
3) They are sold in the same geographic market. Two products are in different geographic markets if A) they are sold in different locations B) it is costly to transport the goods and C) it’s costly for consumers to travel to buy the goods
Term
cross-price elasticity
Definition
shows the degree to which products substitute for each other. It also measures the percentage change in demand for good Y that results from a 1% change in the price of good X
-when it’s positive, it indicates that consumers increase their purchases of good Y as the price of good X increases (they’re substitutes).
Term
Standard industrial classification
Definition
classifies companies by catagories but ignores GEOGRAPHY, USE and assumes they all make the same thing. Provides a 7-digit identifier. It's a good starting point to identify competitors
Term
Ways to measure market structure
Definition
n-firm concentration ratio (the combined market share of the largest n firms), herfindahl index (the sum of squared market shares)
Term
When do you use the herfindahl index
Definition
when the relative size of the largest firms is important
Term
what are the 4 classes of market structure
Definition
Perfect comp (a range of less than .2 with fierce comp), monopolistic comp (rng of less than .2, intensity of comp depends on degree of product differentiation), oligopoly (rng of .2-.6, comp depends on interfirm rivalry), monopoly (rng grater than .6, intensity is light unless there's a threat of entry)
Term
Why is elsticity sharp in a competitive market
Definition
because consumers can shop
Term
What are the conditions for perfect competition
Definition
1) large numbers of firms 2) producing standardized produts (most important characteristic) 3) producers and consumers have complete knowledge of the market (all consumers know about all firms and producers know about compeitition as well 4)firms are price takers becasue the marekt sells the same thing and they have to take the market price 5) easy entry and exit from the market

Term
Factors creating monopolies
Definition
Patent rights (has eroded except in drug mfg), unfair competition (buying all the supplies to prevent competition from having necessary input) pricing by region, natural monopoly (we benefit from this bc as companies grow, prices drop and the government drops our price)
Term
Monopolistic Competition Characteristics
Definition
1) large number of firms 2) producing differentiated products 3) relying on non-price competition (ex- advertising) 4) some (limited) control on price (limited by price elasticity) 5) fairly easy entry and exit from the market
Term
If the demand curve for monopolistic competition goes straight at 3 o'clock, what does that mean
Definition
it's perfect competition and is perfectly elastic (if the firm changes price, sales drop to 0)
Term
If a demand curve for monopolistic competition goes to 4 o'clock, what does that mean
Definition
it's very elastic because of the number of substitutes
Term
What is vertical differeniation
Definition
products unambiguously differ in quality. ex- if a cleaning product is a better formula that really does a better job
Term
What causes the increase in sales when a firm drops its prices
Definition
1) increased sales ot customers who were planning to buy a smaller quantity from the firm 2) sales to customers who weren't planning to purchase from the firm or its competitors, 3)sales to customers who were planning to buy from a competitor but switched to take advantage of the lower price
Term
What is horizontal differentiation?
Definition
Vary in certain product characteristics to appeal to different consumer groups. A big source is geography that allows firms to raise prices in some areas without losing many customers
Term
Characteristics of an oligopoly
Definition
1) small number of large firms dominating the market (ex auto industry with lots of producers but only a few leaders) 2) producing standized or differentiated products (ex steel which is std or cars which are different) 3) mutual interdependence (the actions of 1 firm affect all of the other firms. based on their reactions) 4) prices are rigid (if they change, it's scheduled) 5)difficult entry and exit from the market
Term
For an oligopoly, if a firm changes price and another firm follows, there's a small change in quantity, what happens to demand?
Definition
Demand is inelastic

In an oligopoly, if a firm changes price and another firm ignores the change and then there's a large change in Q, what happens to demand
Definition
Demand is elastic.
Term
Give 2 facts about industry (market) structure.

Term
Give an example of what a strategic compliment/substitute typically is
Definition
Price is a complement and quantity and capacity decisions are usually strategic substitutes
Term
What is a strategic complement?
Definition
When a firm's action induces the rival to take the same action. Ex- when i drop my price, you have to drop yours. One firm's aggressive behavior leads its rival to bahave less aggressively. Happens often in oligopolies
Term
Which happens more often, price changes or mergers?

due entirely to the firm's own tactical decisions
Term
What is the strategic effect of commitment
Definition
It takes into account the
Term
The internet has done what to the direct effect?
Definition
It has shortened reaction time and reduced the direct effect as strategic effect grows. Ex- the airline industry is an oligopology and drops the price. online sellers know first and compeitotrs know at the same time. As a result, there's almost zero direct effect.
Term
What is a tough commitment
Definition
It hurts the competitors and is an effort to outdo one's rivals (ex- capacity expansion or reducing prices. Tyey conform to the traditional view of competition.
Term
What is a soft commitment?
Definition
it's a commitment that helps rivals (ex elimination of production facilities, increase of prices). it may be beneficial if the strategic effect of the commitment is sufficiently positive
Term
Give an example of a non-credible decision.
Definition
K mart saying they'll drop their price by 10%- they couldn't support that decision without going under.
Term
Give the components of the strategic effect
Definition
Commitments that lead to less aggressive behavior from the rivals will have beneficial strategic effect
Term
If you make a decision that involves a strategic substitute, what's the likely response?
Definition
The reaction would be a strategic compliment
Term
If products are horizontally differentiated, what might happen to the strategic effect?
Definition
It may be relatively less important since hte rival doesn't have the incentive to react. Ex- all the fridges are diferentiated by bran, so if 1 drops the price, the others don't have to because they're in different markets

Term
What are the four steps for analyzing commitment intensive decisions?
Definition

decisions by a firm today will affect it's beahvior as well as what?
Definition
it's competitors' behavior in the future
Term
cooperative pricing occurs when?

Collusion is what?
Definition
Firms in a market set a price. It's illegal in US but is legal in other countries.
Term
Tit for tat pricing is what?

A cluster of firms are able to get enough of the market to increase the price and competitors follow. What keeps it there is if a competitor drops the price, it makes everyone do the same and hurts profits. "we will not be undersold" or "lowest price guaranteed"
Term
If a company always drops its price in the fall and raises it in the spring, the other firms will likely do what?
Definition
Keep their prices the same and not worry- this causes stability.
Term
Grim trigger strategy is what?

Term
Both grim trigger and tit for tat are capable of what?
Definition
sustaining cooperative pricing
Term
What factors of market structure affect cooperative pricing?
Definition
Concentration, conditions that affect reaction speeds and detection lags, differences among firms, price sensitivity of buyers.

Cooperative pricing is more likely to happen in what type of markets?
Definition
concentrated, because the revenue loss from a price cut is larger, pootential gain from new customers is smaller and the beneft to cost ratio tilts in favor of higher prices

Definition
it becomes easier to sustain. if you can react quickly, it means that all the firms will know about changes in a price and adjust
Term
What determines reaction speed?
Definition
Lag in detecting price changes, frequency of interactions with the rival, ambiguity regarding which rival is cutting prices, inability to distinguish between price cuts by rivals and lower demand as the cause of drop in sales.
Term
What are relevant structural conditions IRT sustaining cooperative pricing?
Definition
Lumpiness of orders, information availability regarding sales transaction, the number of buyers, volatillity of demand conditions (if the market starts to tank, firms will sell now)
Term
Lag between orders does what to the gain from price cutting?
Definition
It makes it more valuable relative to the cost imposed by a rival's retaliation
Term
With a large number of buyers, is it easy to give price cuts?
Definition
No. It's harder to do secret price cuts
Term
A drop in demand can be misread as what?
Definition
Competitor dropping prices.
Term
A key factor of differences among firms is what?
Definition
market pricing says that all firms make the same prodcut, but that's not true.
Term
Firms differen in incentives they face for cooperative pricing due to what?
Definition
different costs, different capacities, different product qualities. The more differences, the less likely price sensitivity.
Term
horizontal differences reduce/increase buyers' price sensitivity?
Definition
Reduce and deter price cutting because variety segments the market. If the market is narrow, coopertive pricing works well.
Term
Frims can facilitate cooperative pricing by doing what?
Definition
Price leadership, advance announcement of price changes, most favored customer clauses, uniform delivered pricing.
Term
The most favored customer cause does what?
Definition
It allows the buyer to pay the lowest price charged by the seller. It inhibits price competition.
Term

Definition
Less.
Term
High market concentration does what to Cooperative pricing and why?
Definition
Facilitates it by coordinating on the cooperative equilibrium is easier with few firms and increases the benefit-cost ratio from adhering to cooperative pricing.
Term
Firm asymetries does what to Cooperative pricing and why?
Definition
Harms because of disagreemtn over cooperatrive price and coorrdinating on cooperative price is more difficult
Term
High buyer concentration does what to Cooperative pricing and why?
Definition
Harms because it reduces the probability that a defector will be discovered.
Term
Lumpy orders does what to Cooperative pricing and why?
Definition
harms because it decreases the frequency of interaction between competitors, increasing the lag between defection and retaliation.
Term
Secret price terms does what to Cooperative pricing and why?
Definition
increases detection lags because prices of competitors are more difficult to monitor and increases the probability of misreads
Term
Volatility of demand and cost conditions does what to Cooperative pricing and why?
Definition
Harms- increases the lag between defection and realiation by increasing undertainty about whether defections have occured and about identity of defectors
Term
Price sensitive buyers does what to Cooperative pricing and why?
Definition
Harsm and increases the temptation to cut price, even if competitors are expected to match.
Term
What happens to the demand curve as quality increases?
Definition
Deamnd is higher when quality is higher and the cuve gets steeper. The vertical distance between the demand curves is the consumers' willingness to pay for incremental quality.
Term
Entrants are what?
Definition
Firms that produce and sell in new markets
Term
Entrants threaten incumbents how?
Definition
The market share of the incumbents is reduces (unless the market is growing) and price competition is intensified. Also the individual's firms ability to control its price drops
Term
How does entry take place?
Definition
An entrant may be a brand new firm or may be an established firm that is diversifying into a new product/market. this is important for analyzing the costs of entry and the strategic response by incumbents

Term
How do structural barriers to entry exist?
Definition
When incumbents have cost advantages, marketing advantages, and incumbents are protected by favorable govt policy and regs
Term
How do incumbents erect strategic barriers?
Definition
By doing something such as expanding capacity (may expand so much to keep others out), resorting to limit pricing or predatory pricing
Term
Three possible entry conditions of a market are?
Definition
Blockaded entry (the incumbent doesn't need to take any action to deter entry) Accomadated entry (the incumbents shouldn't bother to deter entry because of growing demand or rapid tech change), Deterred entry (predatory acts)
Term
The three main types of structural barriers to entry are?
Definition

Term
What is exit?
Definition

Term
List 3 examples of entry deterring strategies
Definition
Limit pricing, predatory pricing and capacity expansion
Term
How do entry deterring strategies work?
Definition
Incumbents must earn higher profits as a monopolist than as a duopolist and the strategy should change the entrants' expectations regarding post-entry competition
Term
What is limit pricing?
Definition
Set the price sufficiently low to discourage entrants by either having contestable limit pricing or strategic limit pricing. Low prices are an entry detrent if entrant infers that the post entry price will be low.
Term
What's the guarantee of strategic limit pricing?
Definition
lower costs becaues the entrant has limited capacity or rising marginal costs
Term
When does predatory pricing vs limit pricing happen?
Definition
Predatory pricing is directed at entrants who have already entered (selling belwo the short run marginal cost with the expectation of recouping the losses via monopoly profits once the rival exits. Limit pricing is directed at potential entrants
Term
What can an incumbent do to be tough?
Definition
have low costs, an irrational desire for market share, or because there is other compeittion tha t the entrant is unaware of
Term
How does excess capacity help an incumbent?
Definition
An incumbent can credibly threatn to lower the price if entry occurs, can exapnd output at a low cost,
Term
How does excess capacity work to deter entry
Definition
An incumbent has a sustainable cost advantage, market demand growth is slow, incumbent can't back off from the investment in excess capacity and entrant is not the type trying to establish a reputation for toughness
Term
What does industry analysis facilitate?
Definition
Assessment of industry and firm performance (what's happening and where are we going), identification of factors that affect performance (if x then y), determination of the effect of changes in teh business environment on performance and identification of opportunities and threats (SWOT analysis)

Term
What is internal rivalry?
Definition
The competition for market share amont the firms in the industry based on price or non-price dimentsion
Term
What does price competition do?
Definition
it erodes the price cost margin and profitability as well as revenue
Term
What does non-price competition do?
Definition
It doesn't erode profits as severly as price competition if customers are willing to pay a higher price for the improvementsss

Term
How does entry hurt incumbents?
Definition
By cutting into the incumbents' market share and intensifying internal rivalry and leads to a decline in price cost margin
Term
What are the classifications for the 2 types of barriers to entry?
Definition
Exogenous (nature of the industry) or endogenous (incumbents' strategic choices)
Term
What are hte key factors that affect the threat of entry?
Definition
Minimum efficient scale relative to the size of the market, govt policies that favor the incumben, brand loyalty of consumers and value placed by consumers on reputation, entrants' acccess to critical resources (raw material, technical know how and distro network, steepness of the learning curve, netwrok externalities that give the incumbents the benefit of a large installed base, incumbents' reputation regarding post-entry competitive behavior
Term
What does the availability of substitutes and complements do?
Definition
the availability of substitutes erods the demand for the industry's output and the availability of compliments boosts industry demand
Term
What does it mean if a supplier has indirect power?
Definition
If upstream market is competitive
Term
What does it mean if a supplier has direct power?
Definition
