What Determines How Fast Economies Grow? (pages 737744)
Learning Objective: Use the economic growth model to explain why growth rates differ
across countries.
The economic growth model explains growth rates in real GDP per capita over the long run. This model
focuses on the causes of long-run increases in labor productivity, which is the quantity of goods and
services that can be produced by one worker or by one hour of work. Economists believe that two key
factors determine labor productivity: the quantity of capital per hour worked and the level of technology.
Technological change is a change in the quantity of output a firm can produce using a given quantity of
inputs. There are three main sources of technological change:
1. Better machinery and equipment.
A. The Per-Worker Production Function
The economic growth model can be illustrated by using the per-worker production function, the
relationship between real GDP per hour worked and capital per hour worked, holding the level of

C. Technological Change: The Key to Sustaining Economic Growth
D. New Growth Theory
New growth theory is a model of long-run economic growth that emphasizes that technological change
is influenced by economic incentives and so is determined by the working of the market system. Paul
Romer, who developed the new growth theory, argues that the rate of technological change is influenced
by how individuals and firms respond to economic incentives. Firms add to an economy’s stock of

CHAPTER 11 | Long-Run Economic Growth: Sources and Policies 253
B. Is the United States Headed for a Long Period of Slow Growth?
Some economists argue that productivity has become more difficult to measure and that the United States
is likely to experience high rates of growth in the long run. Other economists believe that productivity
entered a long-run decline in the mid-1970s that was only briefly overcome by the effects of the
revolution in information technology (IT).
Extra Solved Problem 11.3
U.S. Productivity Growth and Employment
The textbook describes the productivity slowdown from 1974 to 1995 in which the annual growth rate of
real GDP per hour worked in the United States was 1 percentage point per year lower than during the
19501973 period. Although the reasons for this anemic growth are still not certain, the subsequent
increase in productivity growth from 1996 to 2006 was welcome news to economists. But others have
pointed to a dark lining in this silver cloud. The economic expansion that began after the 2001 recession
Walsh notes that productivity growth and changes in technology cause structural changes that result in
increased production and employment in some industries and reductions in production and employment in
other industries. For example, the growth in demand for word processors and personal computers resulted
in a decline in the demand for typewriters and some types of office workers. Small changes in overall
employment mask what often are large increases in employment and unemployment in individual
industries. In other words, the negative effect of productivity on employment occurs in the short run,
while the positive effect of productivity on employment occurs in the long run.

It’s a story all too familiar to many Americans: Caterpillar, the world’s largest manufacturer of

were much higher than they were at a Caterpillar plant in another country. What was different about the

Why Isn’t the Whole World Rich? (pages 747–756)
Learning Objective: Explain economic catch-up and discuss why many poor countries
have not experienced rapid economic growth.
The economic growth model tells us that economies grow when the quantity of capital per hour worked
increases and when technological change takes place. The profitability of using additional capital or better
technology is generally greater in a developing country than in a high-income country. The economic

What Do Parking Tickets in New York City Tell Us about Poverty
in the Developing World?
In many developing countries, government officials insist on receiving bribes to process most
transactions. For example, someone may need to pay an official before being allowed to open a shoe store
But does corruption cause countries to be poor, or does a country’s being poor lead to its being corrupt?
Some economists have made the controversial argument that corruption may be the result of culture. If a
culture of corruption exists in a country, then the country may have great difficulty establishing an honest
government that is willing to enforce the rule of law. Economists Raymond Fisman of the Columbia
Business School and Edward Miguel of the University of California, Berkeley, came up with an ingenious
CHAPTER 11 | Long-Run Economic Growth: Sources and Policies 257
Of course, ignoring parking regulations is a relatively minor form of corruption. But if Fisman and
Miguel are correct, and a culture of corruption has taken hold in some developing countries, then it may
be difficult to reform their governments enough to establish the rule of law.
Question
The relationship that Raymond Fisman and Edward Miguel found between the extent of corruption in a
country and the number of parking violations committed by the country’s United Nations delegates in
New York isn’t perfect. For example, “Ecuador and Colombia both have perfectly clean parking slates,
despite the experts’ view of them as fairly corrupt places.” Does this observation invalidate Fisman and
Miguel’s conclusions about whether the parking violations data provide evidence in favor of there being a
culture of corruption in some countries? Briefly explain.
