9.1 Innovation boosts growth

Context and scope
- The lecture emphasizes how industry in America exploded in the late 1800s, after the Civil War, leading to a second industrial revolution that was far larger than the first one.
- By the end of the period, America becomes one of the greatest industrial nations. By 1900, America will produce more steel than all the European countries combined. This illustrates the scale of growth and the global significance.
The five factors contributing to industrial growth in America
- Factor 1: Natural resources
- Factor 2: A large labor force
- Factor 3: Free enterprise (economic system)
- Factor 4: Government policies (tariffs and related policies)
- Factor 5: Innovations and inventions (new technologies and ideas)
Contextual examples and background (not tested content, but relevant)
- Lowell girls: early factory labor example from the pre-Civil War/early industrial era.
- Early trains and communication systems: examples of innovations contributing to economic growth.
Deep dive: Natural resources (Factor 1)
- Definition: Natural resources are the things found in nature that we can use to make things.
- The four major resources essential for industrial growth in America: lumber, oil, coal, and iron (iron ore).
- Geographic rationale for abundant resources
- The United States is geographically large, which provides a wide base of resources.
- The speaker emphasizes size as a key reason for resource abundance. The country ranks as the third largest in the world by area, after $Russia$ and $Canada$ .
  - The big size means access to vast quantities of minerals, wood, oil, coal, and other resources.
- Four major resource categories (with initial notes and uses)
- Lumber
  - Abundant forests provide wood for construction of factories and other needs.
- Oil
  - In the modern (late 19th century) context, oil is used to power machinery via lubrication and, in later times, for gasoline and plastics. The lecturer notes that in the 1800s, oil’s role was primarily lubrication for machinery; later uses expanded.
- Coal
  - Served as the fuel to run steam engines; coal burns at a steady temperature to produce steam from water, enabling many early machines and factories to operate.
- Iron
  - Iron ore is the raw material for steel. Steel is described as being lighter and stronger than iron, making it preferable for construction and manufacturing.
  - The contrast is explained with a general idea that steel’s advantages (strength and weight) contributed to industrial efficiency and capabilities; iron alone would have required more financing and limitations.
- Why resource abundance matters
- Other nations may want to industrialize but lack one or more of these critical resources. The combination of plentiful resources and large geographic size gave the United States a comparative advantage for sustained industrial growth.
- Summary takeaway for natural resources
- The scale and variety of resources, combined with geographic size, underpinned the United States’ industrial expansion in the late 19th century and beyond.
Contextual notes on what to remember about 9.1
- These points set the stage for understanding why the United States could accelerate industrial growth during the post-C Civil War era and through the end of the 19th century.
- The discussion frames economic growth in terms of resource endowments, labor capacity, policy environment, organizational structures (free enterprise), and the pace of innovation.
Connections to broader themes
- This material links to foundational principles of economic development: factor endowments, technology adoption, and policy influences.
- The second industrial revolution (late 19th to early 20th centuries) is contrasted with the first industrial revolution that occurred earlier (pre-Civil War), with the current discussion emphasizing the more expansive and transformative nature of the later period.
Numerical references and LaTeX formatting
- The claim about steel production by the year $1900$ : more steel than all European countries combined.
- Timeframe references: the last three decades of the $1800s$ (the $1870s$ , $1880s$ , and $1890s$ ).
- Country sizes: the United States is the third largest country, after $Russia$ and $Canada$ .
Key terms
- Second Industrial Revolution: a broader, later wave of industrialization characterized by rapid technological change and scale.
- Free enterprise: an economic system in which private individuals and businesses have the freedom to operate competitively for profit with limited government intervention.
- Tariffs and government policies: policies that can protect domestic industries (tariffs) and shape economic growth.
- Innovations and inventions: new technologies and ideas driving productivity and expansion (e.g., trains, communications).
Potential exam-style questions
- List the five factors contributing to industrial growth in America and give a brief explanation of each.
- Explain why natural resources and geographic size were particularly important for the United States’ industrial expansion in the late 19th century.
- Compare the roles of iron and steel in industrial growth and explain why steel was advantageous.
- How did government policies (tariffs) interact with free enterprise to influence industrial expansion?
- Provide two examples of innovations or inventions from this period and discuss their impact on growth and productivity.
Summary takeaway
- The late 19th-century industrial boom in the United States was driven by a combination of abundant natural resources, a large labor force, a favorable economic system (free enterprise), supportive government policies (tariffs), and rapid innovations and inventions. The country’s vast size and resource base were critical enablers of this transformation, enabling production scales (e.g., steel) that outpaced rivals and reshaped the global economy.
