Courbe WS et Économie du Travail

Introduction

• The WS curve (Wage-Setting) represents the relationship between the real wage and the level of employment.
• It illustrates the nominal wage that firms are willing to pay workers considering the equilibrium level of employment.
• The WS curve is upward sloping, indicating that higher employment levels are associated with higher real wages.

Factors Influencing the WS Curve Shape

• Market power of firms: Larger firms typically have more negotiating power, leading to less responsive wage adjustments to employment levels.
• Bargaining power of workers: Strong labor unions or worker organization can lead to real wages that are relatively insensitive to employment changes.
• Expectations: Expected inflation and future wage adjustments affect worker and firm expectations. Higher expected inflation implies a higher nominal wage demand.
• Productivity: Increases in labor productivity will reduce wage demands. Higher productivity thus leads to a shift downwards in the WS curve.
• Unemployment rate: Higher unemployment levels often correlate with reduced wage demands, with a corresponding shift downwards or left in the WS curve.
• Economic Conditions: Overall economic prosperity or downturns influences real wages and employment. More expansionary conditions can lead to a shift upwards and to the right
• Government policies: Wage policies or minimum wage laws often influence the shape and position of the WS curve.

Determinants of the WS Curve's Position

• Productivity: Higher productivity tends to shift the WS curve downwards as firms can afford to pay higher wages while still delivering profits.
• Worker bargaining power: Strong labor unions or worker organization usually lead to a higher position of the WS curve.
• Economic conditions: A buoyant economy often leads to a shift upwards in the curve, as both firms and workers demand higher wages. Conversely, during recessions, the WS curve shifts downwards.
• Legal minimum wages: Minimum wage laws directly impact the WS curve by establishing a minimum that firms must pay. Higher minimum wages result in a shift to a higher position.
• Social norms: Expected wages and social norms about wages influence workers' demands and firms' willingness to pay.
• Wage indexation: When contracts adjust wages based on inflation, it directly affects the position of the WS curve.

Intersection with the PS Curve

• The WS curve intersects with the PS curve (Price-Setting) curve to determine equilibrium real wage and employment levels.
• The point of intersection is crucial in determining the equilibrium employment and wage rates.

Shifts of the WS Curve

• Changes in labor market conditions: Stronger or weaker labor unions, productivity shocks, and changing unemployment levels all cause shifting in the curve.
• Public policies: For example, government-mandated wage increases or minimum wage laws will cause upward shifts in the WS curve.
• Inflation expectations: Changes in inflation expectations will produce an upward or downward shift in the WS curve depending on whether expectations increase or decrease.
