GRADED A+
◍ Human Factors.
Answer: Bounded Rationality: limited human capacity to anticipate and
solve problemsOpportunism: to be self-seeking with guile
◍ Market Factors.
Answer: Uncertainty: changes in consumer demand needs, contract
termsNumber of firms: Large number; competitive, small number; market
power
◍ Producing within the firm.
Answer: Bounded rationality + High uncertainty = High TC, produce
internallyOpportunistic individuals + Small number = High TC, produce
internally
◍ Sourcing from the market.
Answer: Bounded rationality + low uncertainty = Lower TC, source from
marketOpporunistic individuals + high number = lower TC, source from
market
◍ remote environment.
Answer: ECONOMIC TRENDS, GOVERNMENT/REGULATORY
TRENDS, TECHNOLOGICAL TRENDS, SOCIOCULTURAL
◍ Limits to size.
Answer: Increasing size of the firm raises costs - limiting the span of control
by managers: increased difficulty in monitoring employees- bounded
rationality- internal coordination costs
,◍ Task Environment.
Answer: focus of the 5 forcesindustry analysis based on industrial
organization economic (SCP)
◍ threat of entry.
Answer: New entrants motivated to enter and compete due to above normal
economic profits earned by existing firms- Increases industry competition-
Reduced performance of incumbent firms• With free entrance, performance
tends to competitive levelsPOTENTIAL RIVALS
◍ Barriers to entry.
Answer: cost of entry by new firms relative to firms already in the market-
high cost detours entry - determines sustainability of above normal
economic profits-protects incumbent firm's profits
◍ Mergers and Acquisitions.
Answer: Definition: a transition in which the assets of one or more firms are
combined in a new firm
◍ 8 ENTRY BARRIERS:.
Answer: • economies of scale• capital requirements• access to distribution•
Product differentiation / brand identity • natural cost advantages• learning
curve• access to necessary inputs• government policy
◍ Barriers toEntry: economies of scale.
Answer: - High cost of fixed investment- Fixed demand and high market
share of incumbentsforces entrance at sub-optimal scale → Higher cost
tonew entrant
◍ Vertical merger.
Answer: a firm combines with its supplier
◍ Horizontal merger.
Answer: firms that compete within the same market combine
◍ Conglomerate merger.
Answer: firms in unrelated lines of business combine
, ◍ Residual Demand Elasticity.
Answer: ni = nd * n - e0(n - 1)ni = firm residual demand elasticitynd =
market demand elasticityn = number of firms e0 = supply elasticity of other
firms
◍ Residual Demand Curve.
Answer: Di = D(P) - S0(P)Di = residual demandD(P) = demand at price
PS0(P) = supply at price P
◍ Quantity produced (firm).
Answer: q = Q/n
◍ Quantity produced by other firms.
Answer: Q = (n-1)q
◍ Structure.
Answer: ni = nd * n - e0(n - 1)
◍ Conduct.
Answer: (P - MC) / P = 1/niLerner Index: economic measure of a firm's
monopoly power
◍ Barriers toEntry: product differentiation.
Answer: - Incumbents have brand identity and customer loyalty • New
entrants face higher advertising costs tochange consumer behavior• e.g. U.S.
Brewing Industry (Budweiser)
◍ Benefits of Contracting.
Answer: Farmers transfer some of the price risk to processorsAllows
processors to have a steady flow of productsIncentive to produce higher and
more consistent product quality to satisfy demand
◍ Measure of Concentration.
Answer: CR4 Ratio: market share of 4 largest firms in the industry Very
high >75%High 65%-75%Moderately high 50%-65%Moderately low
35%-50%low <35%
◍ Barriers toEntry: natural cost advantage.
