Productivity Notes

How Does Productivity Determine How Much a Society Can Produce with Its Resources?

1. At its simplest, productivity answers the question: how much can we make with what we have?
2. If two countries have the same number of workers and similar natural resources, but one produces far more goods and services, the difference is usually productivity.
3. A common measure is labour productivity, calculated as: $$\text{Labour productivity} = \frac{\text{Total output}}{\text{Number of workers (or hours worked)}}$$
4. If productivity rises, a country can potentially achieve:
   1. Higher incomes (workers can be paid more because each worker produces more value)
   2. Higher profits (firms can earn more from the same workforce)
   3. More tax revenue (governments can fund services more easily)
   4. Improved living standards (more and better goods and services become affordable)

Why Is Human Capital A Major Driver of Productivity?

1. When people are healthier and better educated, they tend to:
   1. work more effectively (fewer sick days, better physical and cognitive capacity)
   2. use technology and equipment more efficiently
   3. be more innovative and entrepreneurial
   4. adapt more quickly to new tasks and changing markets

How Does Low Productivity Trap Countries in a Cycle of Low Incomes?

1. Productivity is not only an outcome; it can also be part of a development trap.
2. When productivity is low:
   1. Firms produce less per worker, so wages stay low.
   2. Households have limited spending power, so demand for goods and services is weaker.
   3. Governments collect less tax revenue, limiting investment in public services.
   4. Low investment in education, health, and infrastructure keeps human capital and business capacity low.
3. This circular pattern is especially damaging in less economically developed countries, where the difficulties experienced by individuals are more acute.

Why Are Economic Growth and Productivity Closely Linked, But Not Identical to Development?

1. Economic growth usually means an increase in total output (often measured by GDP).
2. Productivity growth is one of the most powerful long-run causes of economic growth because it increases output without needing a proportional increase in inputs.
3. However, growth is not the same as development.
   1. Development involves broader improvements in well-being, such as health, education, and living conditions.

How Do Institutions and Infrastructure Shape How Productive an Economy Can Become?

Productivity depends heavily on the environment in which households and firms make decisions.

1. Two crucial enabling factors are:
   1. Infrastructure (roads, power supply, internet connectivity, ports, clean water systems): lowers transport and transaction costs and reduces downtime.
   2. Institutions (laws, government effectiveness, rule of law, low corruption, predictable regulation): encourage investment, reduce uncertainty, and support fair competition.
2. In developing countries, inequality and weak development can be reinforced by issues such as:
   1. unequal access to education and credit
   2. poorly developed infrastructure
   3. unsupportive institutional frameworks (including corruption and heavy bureaucracy)
   4. All of these can reduce the ability of firms to invest and innovate, lowering productivity.

What Is The Connection Between Productivity, Capitalism, and Inequality?

1. Productivity growth increases total income in a market economy, but distribution is uneven
2. Under capitalism, private ownership means profits flow to asset owners, while workers earn wages
3. Productivity gains may raise wages, but not automatically or equally
4. Unequal access to education, credit, and ownership concentrates gains among certain groups
5. Thomas Piketty’s theory: when r>gr>g, returns on capital grow faster than the economy, increasing wealth inequality

What Are Some Ways Countries And Communities Can Raise Productivity?

1. Investing in education and health to build human capital.
2. Improving infrastructure so firms can operate reliably and reach markets.
3. Supporting access to credit so entrepreneurs can invest in equipment and expansion.
4. Strengthening institutions to reduce corruption, simplify bureaucracy, and protect property rights.
5. Encouraging appropriate trade and specialization, so resources shift toward sectors with comparative advantage.
