The real wage ($$w$$) represents the purchasing power of earnings and is a central variable in the WS-PS model. It is defined as the nominal wage ($$W$$) adjusted for the general price level ($$P$$), calculated with the formula: $$w = \frac{W}{P}$$

Real Wage Formula in the WS-PS Model

The graphical derivation of the Phillips curve from the wage-setting and price-setting (WS-PS) model visually demonstrates the model's core prediction: lower unemployment leads to higher wage and price inflation. This process constructs the inverse relationship between unemployment and inflation, linking the supply-side mechanics of the labor market to the empirically observed Phillips curve.

Graphical Derivation of the Phillips Curve from the WS-PS Model

An economy experiences a year where the average nominal wage for workers increases by 5%, while the general level of prices for goods and services increases by 8%. Based on this information, what is the most accurate conclusion about the workers' purchasing power during this year?

Based on the provided scenario, critically evaluate the union leaders' claim of a 'major victory.' Is the average worker in this union better or worse off in terms of their ability to purchase goods and services? Justify your answer with a clear explanation.

Evaluating a Wage Negotiation Outcome

In a given year, a worker's nominal wage is $60,000. The economy's general price level, as measured by a price index, is 120 (relative to a base year value of 100). Calculate the worker's real wage in terms of base-year prices and explain what this value represents in terms of purchasing power.

Calculating and Interpreting Real Wage

The real wage ($$w$$) is defined as the nominal wage ($$W$$) divided by the general price level ($$P$$). This relationship is expressed by the formula: $$w = \frac{W}{P}$$. It is a foundational assumption within the WS-PS model.
