In-Depth Notes on Employment and Labour Markets

Objectives of Unit 7

• Determinants of the level of unemployment
• Factors behind the wage level in a country
• Clarification of unemployment during "full employment"
• Exploration of high unemployment rates in certain countries

Outline of Unit 7

• The Demand for Labour
• The Supply of Labour
• The Market for Labour
• The Natural Rate of Unemployment
• The Market for Capital

Applying Previous Concepts

• Average salaries and employment levels can be analyzed using the market model for labour services.

7.1 The Demand for Labour

• The demand for labour is influenced by the desire to produce goods and services.
• Factors affecting demand include:
  • Product market conditions
  • Productivity levels

Understanding Demand with Graphs

• Diminishing Marginal Product and Value of Marginal Product (VMP) of Labour:
  • Example table illustrating labor demand and marginal products:
  • At labor unit 10, VMP = $900;
  • At labor unit 20, VMP = $700;
  • Conversely, at labor unit 50, VMP = $100.
• The relationship between the price of a product and labour demand.

Impact of Product and Productivity Changes

• Change in Product Price:
  • When the product price falls, the value of marginal product also decreases, resulting in a shift in labour demand.
• Change in Workforce Productivity:
  • If productivity of labour increases, the VMP would rise, leading to a potential increase in demand for labour.

7.2 The Supply of Labour

• The supply of labour reflects a trade-off with leisure.
• Factors influencing the choice between labour (work) and leisure:
  • Individual preferences (utility)
  • Available time (feasibility)

Labour-Leisure Choice Graphs

• Illustrations show how wage rates affect the labour supply curve.
  • Higher wages increase the supply of labour.

Average Working Hours vs. GDP

• Observations indicate that individuals in wealthier countries may work fewer hours.

7.3 The Market for Labour

• The labour market can be modeled similar to other markets, with interactions between labour demand and supply leading to employment and wage levels.

Expected Market Changes

• Immigration Impact:
  • Hypothetical scenario discussing the implications of reduced immigration on American labour markets.
• Case Studies:
  • Israel's wage increases due to labor constraints;
  • China's economic reforms and resultant demand spike.

7.4 The Natural Rate of Unemployment

• Definition: Percentage of the labour force that is unemployed.
• Formula:
  $\text{Unemployment Rate} = \frac{\text{Labour Force} - \text{Employed}}{\text{Labour Force}} imes 100$
• Types of Unemployment:
  • Cyclical
  • Frictional
  • Structural
• Discuss reasons for persistent unemployment in an economy.

Factors Influencing Wage Rigidity

• Reasons explaining why nominal wages remain sticky:
  • Menu costs
  • Coordination failures
  • Money illusion

Unemployment in Developing Countries

• Comparative statistics showing higher unemployment rates in poorer countries; structural issues affecting their labour markets include:
  • Lack of skilled labor
  • Inefficient market attributes

7.5 The Market for Capital

• Comparison of capital markets to labor markets, emphasizing their differences:
  • Capital as a rental market; easier supply adjustments compared to labour.
  • Demand influenced by marginal productivity.

Market Dynamics

• Observations highlighting that wages typically rise at a faster rate than capital costs over time, illustrating labour versus capital intensive products.

Summary of Capital and Employment Trends

• Over decades, labour market dynamics have shown that wages trend upwards significantly compared to the cost of capital due to shifts in production methods and capital adjustments.
