ECN202: Macroeconomics
1980s: Economic Growth nations "justify their existence, in large part, by securing
their citizens' well-being, whether by creating and maintaining jobs, providing a social safety net, or protecting
the environment,"
A Divided World
"key global problem of the final years of the twentieth century: unbalanced wealth and resources, unbalanced demographic trends, and the relationship between them....we are heading into the twenty-first century in a world consisting of the most part of a relatively small number of rich, satiated, demographically stagnant societies and a large number of poverty-stricken, resource-depleted nations whose populations are doubling every twenty five years or less.”
How did this happen because it was not always this way? In this unit we will look at the topic of economic growth since it is responsible for this divided world. We’ll start with a few headlines and then look at some graphs that capture the essence of the problem and then we’ll look more closely at the process of economic growth to see what separates the winners from the losers.

Economic Growth: The Long View
How did it happen?
Small differences matter in long-run
In 60 years here is what $1,000 grows to @
1% = $1,8002% = $3,2003% = $5,900
Annual growth rates picked up after the industrial revolution in the 1700s
Why does this look different from the previous graph?
What caused the separation? Collapse of China
“The world history of technology is the story of a long, protracted inversion. As late as the end of the fist millennium of our era, the civilizations of Asia were well ahead of Europe in wealth and knowledge. The Europe of what we call the Middle Ages (say, tenth century) had regressed from the power and pomp of Greece and Rome, had lost much of the science it had once possessed, and seen its economy retreat into generalized autarky…. Five hundred years later the tables had turned.”
What caused the separation? Collapse of the Middle East
“A millennium ago, around roughly the tenth century, the Middle East was an economically advanced region of the world, as measured by standard of living, technology, agricultural productivity, literacy or institutional creativity. Only China might have been more developed. …By the nineteenth century, the entire Middle East was clearly “underdeveloped” relative to western Europe and its offshoots in the new world; and by the twenty-first century it had fallen markedly behind parts of the Far East as well.”
Is economic growth progress?
Growth is good!!

2. "Another set of arguments [for economic growth] is political —having to do with the claim that economic [growth] engenders greater political stability and reduced potential for conflict." Lawrence Summers in "Reflections on managing global integration“
3. "The success or failure of any country over the next thirty years hinges on growth." Hamish McRae, The World in 2020
1. "Historically, the biggest constraints on growth have come mainly from three sources: political conflict rooted in a clash of interests or ideologies; social stress arising from economic disparities that produce misery amid wealth; and, finally, and increasingly in the future, ecological constraints on growth.“
2. “It is time to understand the environment for what it is: the national-security issue of the early twenty-first century.” Robert Kaplan, “The Coming Anarchy”

Decomposition of growth: The theory
From your work with production possibility curves you know that growth can come from two sources: you can throw more resources at the problem or you can get more efficient. It turns out it makes a big difference where that growth comes from. If it comes from more resources, eventually there may not be additional resources. For example, in the US the movement of women out from the homes and into the labor force increased resources that added to national output. The problem is eventually the participation of women will equal men and there will be no surplus of women to mobilize. The same thing is true in China where the high growth rates come from the movement of people into factories, but once the move is over, growth will slow. Productivity growth, however, is sustainable so growth can continue indefinitely if it comes from this source. Now let’s look at the decomposition in an equation and then look at the situation in the US where two demographic shocks have affected the composition of growth.
Decomposition of growth: The theory
Growth rate version
(y/p) = (y/l) +(l/p)
– (y/p) = growth rate of GDP per person– (y/l) = growth rate in labor productivity (intensive
growth = more productive)– (l/p) = growth rate in labor’s share of the
population (extensive growth = more resources)

Economic Growth Theory: How Does It Happen?
• Classical model (depressing)– Malthus (dismal science)
• Neoclassical model (encouraging)– Inputs & productivity
• Physical and human capital
Factors Affecting Economic Growth
1. Location (Guns, Germs & Steel)
Determinants of growth: Location

2. Structural change 1. Cost disease of service sector
Cost-disease of service sector
(2) p = w - % (Q/L)Where• p = % price• w = % wages• % (Q/L) = productivity growth rate
Here is your explanation of why tuition is rising so rapidly – because productivity growth is so low in college (productivity = class size) that any wage increase will show up as a tuition increase. Compare that to manufactures (computers) where productivity grows rapidly so there can be wage increases and prices can still fall.

4. Savings & investment (physical, human, and public capital)

“the composition of America's public R&D has changed dramatically in recent years, and perhaps excessively. Whereas most R&D spending was roughly flat (in constant dollars) through the 1990s, health-related R&D went soaring into the stratosphere—almost literally, given that the level now nearly matches, and may soon exceed, spending on space research at its peak, in the moon-shot years. …
In sum, the demands of two politically mighty generations [boomers and retirees] have shifted government's priorities toward consumption as a general matter and, within the R&D budget, toward the sort of research that most resembles consumption.”

6. Institutions

2. Market-oriented (capitalist vs communist)

4. Political stability

6. Colonial legacy
“Through a broad multiplicity of historical examples, they show how institutional developments … have had enormous consequences. The openness of society, its willingness to permit creative destruction, and the rule of law appear to be decisive for economic development.”Why Nations Fail: The Origins of Power, Prosperity, and Power by Daron Acemoglu and James Robinson
Now let’s look at a few international comparisons
What does this tell us about economic growth?
• “When a society moves from rulers who demand money in exchange for protection (and under implicit threat of violence) to nonviolent rulers who charge taxes in a framework of law, the stage is set for economic growth. The Romans were the first in the West to establish a wide area within which business could be transacted relatively safely.” Peter Temin, "The Economy of the Early Roman Empire," Journal of Economic Perspectives, Winter 2006
• “The Chinese state was always stepping in to interfere with private enterprise, to take over certain activities, to prohibit and inhibit others, to manipulate prices, to exact bribes. Still, the goal, the aim, the ideal was the ineffable stillness of immobility... The ingenuity and inventiveness of the Chinese, which have given so much to mankind, would no doubt have enriched China further and probably brought it to the threshold of modern industry, had it not been for this stifling state control.” David Landes, "Why Europe and the West? Why Not China?," JEP Spring 2006
