Managers and Economics
W
hy should managers study economics? Many of you are
probably asking yourself this question as you open this text.
Students in Master of Business Administration (MBA) and
Executive MBA programs usually have some knowledge of
the topics that will be covered in their accounting, marketing, finance, and
management courses. You may have already used many of those skills on
the job or have decided that you want to concentrate in one of those areas in
your program of study.
But economics is different. Although you may have taken one or two introductory economics courses at some point in the past, most of you are not
going to become economists. From these economics classes, you probably
have vague memories of different graphs, algebraic equations, and terms such
as elasticity of demand and marginal propensity to consume. However, you
may have never really understood how economics is relevant to managerial
decision making. As you’ll learn in this chapter, managers need to understand the insights of both microeconomics, which focuses on the behavior of
individual consumers, firms, and industries, and macroeconomics, which analyzes issues in the overall economic environment. Although these subjects are
typically taught separately, this text presents the ideas from both approaches
and then integrates them from a managerial decision-making perspective.
As in all chapters in this text, we begin our analysis with a case study. The
case in this chapter, which focuses on the global automobile industry, provides an overview of the issues we’ll discuss throughout this text. In particular, the case illustrates how the automobile industry is influenced by both the
microeconomic issues related to production, cost, and consumer demand and
the larger macroeconomic issues including the uncertainty in global economic
activity, particularly in Europe, and the value of various countries’ currencies
relative to the U.S. dollar.

Case for Analysis
Micro- and Macroeconomic Influences on the Global Automobile Industry
In September 2012, U.S. automobile sales increased to 1.19
million cars and light trucks per month, a 12.8 percent increase
from a year earlier. This increase represented an annualized rate
of 14.94 million vehicles, the highest sales rate since March
2008 before the recession began in the United States. Much of
the increase was driven by passenger car sales at Toyota Motor
Corp., Honda Motor Co., and Chrysler Group LLC. There was
a significant increase in sales for Toyota and Honda from the
previous year, as both companies were recovering from the
earthquake that hit Japan in March 2011.1 Analysts noted similar increases in August 2012 that were attributed to pent-up
consumer demand for replacing aging vehicles and the lowinterest financing and other incentives Japanese auto makers
offered to regain market share lost in 2011 due to the lack of
availability of their cars.2
Automobile production in the United States had expanded
in 2012, given favorable foreign exchange rates and a plentiful supply of affordable labor. Toyota, Honda, and Nissan
Motor Co. all increased their production capacity in the
United States with the goal of shipping automobiles to
Europe, Korea, the Middle East, and other countries. The
strong value of the yen, and conversely the weak U.S. dollar,
gave Japanese producers the incentive to produce cars in the
United States for export around the world. This investment
by foreign automobile producers helped the U.S. economy
that was still struggling to recover from the recession of
2007–2009. Automobile industry employment in the United
States was estimated to increase from 566,400 in 2010 to
756,800 in 2015. Although these estimates were well below
the 1.1 million automobile workers employed in 1999, they
indicated that the economic recovery was moving forward.
General Motors Co., which had once encouraged auto parts

suppliers to relocate in low-wage countries, now encouraged
them to locate near U.S. auto plants.3
U.S. auto producers, who had once essentially lost the competition to their Japanese rivals in the 1980s and 1990s and
who went through government-backed (GM and Chrysler)
or private (Ford) restructurings during the U.S. recession,
regained profitability and invested in the engineering and redesign of their cars. Several Fords were designed with a voiceoperated Sync entertainment system, and the Chevrolet Cruze
that was launched in 2010 came with 10 air bags compared
with 6 for the Toyota Corolla. As the U.S. economy recovered,
Americans also began purchasing more trucks and sport-utility
vehicles (SUVs), which helped to restore profits and market
share for the Detroit auto makers. Trucks and SUVs made up
47.3 percent of the U.S. market in 2009, 50.2 percent in 2010,
and 50.8 percent in 2011. This segment of the market had been
hit particularly hard during the U.S. recession.4
As the U.S. automobile industry revived, the competition
between Ford and GM again became more intense. In 2008,
Ford supported the government bailout for GM and Chrysler
because Ford was worried that a collapse of these companies
would also impact the auto parts industry. As the domestic
auto industry recovered, Ford, which had often focused just
on Toyota as its key competitor, began developing strategies to
counter GM. Ford realized that customers who had long been
loyal to Asian brands were again looking at U.S. cars, given the
generally perceived quality increases in the U.S. auto industry.5

PART 1 Microeconomic Analysis
Japanese auto makers in 2011 and 2012 faced managerial
decisions that were influenced both by the nature of the competition from their rivals and by macroeconomic conditions,
most importantly the value of the exchange rate between the
yen and the U.S. dollar.6 Production by both Toyota and Honda
was hit by the earthquake and tsunami in Japan in March 2011
and by subsequent flooding in Thailand that disrupted the supply of electronics and other auto parts made there. Toyota sales
were also influenced by the recall and quality issues in 2010
related to the gas pedal and floor mat design. Honda’s redesigned 2012 Civic was criticized for its technology and lessthan-luxurious interior. The car was dropped from Consumer
Reports’ recommended list in August 2011. Honda officials
acknowledged that they had underestimated the competition
from U.S. producers.
The strong yen, which made exports from Japan less price
competitive, also gave the Japanese producers the incentive
to produce their cars in the United States. Honda, which had
produced 1.29 million vehicles in North America in 2010,
planned to open a new plant in Mexico and expand production in all seven of its existing assembly plants to 2 million
cars and trucks per year. Production abroad was a particular issue for Toyota, which made half of its automobiles
in Japan, compared to Honda and Nissan, which produced
about one-third of their output in Japan. The president of
Toyota, Akio Toyoda, grandson of the company founder, had
made a public commitment to build at least 3 million cars
in Japan annually, half of which would be for export. Some
company officials argued for streamlining production in
Japan by decreasing production without raising costs, essentially redefining the economies of scale in the company’s
production process. These officials believed the company
could meet domestic goals with high-precision production,
cost-cutting, and collaboration on new technology with parts
suppliers.
Auto producers also focused on China during this period,
although there was concern about the slowing Chinese economy.7 Auto sales in China increased only 2.5 percent in 2011
compared with increases of 46 percent in 2009 and 32 percent

in 2010. However, the size of the Chinese economy continued to be the major incentive for expansion in that country. In
April 2012, Ford announced that it would build its fifth factory in eastern China as part of its plan to double its production capacity and sales outlets in the country by 2015. This
production increase would make the company capable of
producing 1.2 million passenger cars in China, approximately
half of the number of cars it built in North America in 2011.
Ford lagged behind other major auto producers in entering
the world’s largest car market. Ford’s strategy was to build
cars from platforms developed elsewhere to minimize costs.
However, these platforms might not provide enough space
in the back seats to appeal to affluent Chinese, who often
employed drivers. General Motors developed a partnership
with Chinese SAIC Motor Corp. to become the dominant foreign competitor in China. This partnership resulted in production changes such as designing Cadillacs with softer corners,
dashboards with more gadgets, and increasing the comfort of
the rear seats to appeal to Chinese consumers. The challenge
for GM was that SAIC could also use GM’s expertise and
technology to make itself a major competitor with the U.S.
company. In 2012, the Chinese automobile industry began
increasing exports, although these were not thought to be a
threat in developed markets in the United States and Europe,
given perceived quality issues including lack of air-conditioning and power windows. However, Chinese producers were
making inroads into emerging markets in Africa, Asia, and
Latin America.
The other major influence on the global auto industry in
2011 and 2012 was the recession and economic crisis in
Europe.8 In October 2012, Ford announced a plan to cut its
operating losses in Europe by closing three auto-assembly and
parts factories in the region, reduce its workforce by 13 percent, and decrease automobile production by 18 percent. Ford
predicted a loss of $1.5 billion in Europe in 2012 and a similar
loss in 2013. The cost-cutting in Europe was combined with
the introduction of several new commercial vans and SUVs and
the introduction of the Mustang sports car for the first time. All
European auto makers faced decreased car sales and chronic
overcapacity at this time. Daimler AG, maker of MercedesBenz automobiles, announced that it would not achieve its
profit targets, while PSA Peugeot Citroen SA announced a
government bailout of its financing arm and a cost-sharing
pact with General Motors. There had been a smaller decrease
in auto-producing capacity in Europe since the 2008 financial
crisis compared with that during the restructuring of the U.S.
auto industry that was influenced by the federal government
bailout.
