The WS-PS Model
Nash Equilibrium
The WS-PS Equilibrium as a Nash Equilibrium
The intersection of the wage-setting (WS) and price-setting (PS) curves represents a Nash equilibrium for the economy. This means it is a stable outcome where no individual actor—whether a firm, an employed worker, or an unemployed person—can improve their situation by unilaterally changing their strategy. Specifically, firms have no incentive to alter the wage or price, or to change the number of workers they hire. Similarly, workers have no incentive to change their effort level, and unemployed individuals cannot secure a job by offering to work for a lower wage.

In an economy where wages are determined by bargaining between firms and workers, and prices are set by firms adding a markup over their labor costs, imagine that a widespread decrease in market competition allows all firms to sustainably increase their price markup. Based on this change alone, what is the predicted impact on the economy's equilibrium?
Equilibrium Unemployment in the Wage-Price Setting Framework
Evaluating a Labor Market Policy
In an economy where equilibrium is determined by the interaction of a wage-setting relationship and a price-setting relationship, consider a scenario where a wave of mergers permanently reduces the level of competition in the product market. Assuming no other changes, what is the resulting impact on the economy's equilibrium real wage and equilibrium level of employment?
Consider an economy where wage and price levels are determined by the interplay between firms' price-setting behavior and workers' wage-setting demands. If the government significantly increases the generosity and duration of unemployment benefits, how would this policy change be represented in the standard wage-setting/price-setting framework, and what would be the resulting effect on the equilibrium level of unemployment?
Analyzing Economic Trends with the WS-PS Framework
True or False: In an economic model where equilibrium is determined by the interaction of a wage-setting curve and a price-setting curve, a new government policy that significantly increases the bargaining power of labor unions will result in a higher equilibrium real wage and a higher equilibrium level of employment.
In an economic model where firms set prices as a markup over wage costs and workers' wage demands increase with the level of employment, consider a situation where the prevailing real wage is higher than the level consistent with firms' target profit margins. Which of the following outcomes is the most likely immediate reaction from firms?
In the context of an economic model that determines the equilibrium real wage and employment level by linking the labor market and the goods market, match each component of the model to its correct description.
In a model of the aggregate economy, the equilibrium real wage and employment level are determined by the interaction of two key relationships. One relationship, the 'wage-setting curve', reflects how wages are determined by labor market conditions. The other, the 'price-setting curve', reflects how firms set prices based on their costs and the competitive environment. Match each economic event below to its most direct impact on one of these curves.
The WS-PS Model as a Framework for Income Distribution
In an economic framework where firms determine prices by setting a markup over their wage costs, a decrease in the real wage level that is consistent with firms' pricing decisions necessarily implies that the share of output per worker claimed by firms as profit has increased.
In an economic framework where the equilibrium real wage and employment are determined by the interaction of a wage-setting (WS) relationship and a price-setting (PS) relationship, consider a situation where the level of employment is temporarily above the equilibrium level. Arrange the following events in the correct chronological order to show how the economy adjusts back towards equilibrium.
In an economy described by a wage-setting (WS) and price-setting (PS) framework, suppose a temporary surge in demand pushes employment above its equilibrium level. Arrange the following events in the logical sequence that describes how the economy would adjust back towards its equilibrium.
Impact of Income Tax on Labor Market Equilibrium
In the economic framework that determines the equilibrium real wage and employment level, the point where the wage-setting and price-setting curves intersect represents a stable outcome where no single economic agent (firm, employed worker, or unemployed person) has an incentive to unilaterally change their behavior. This type of stable outcome is known as a(n) ____ equilibrium.
Analyzing a Productivity Shock in the WS-PS Framework
In an economic model where the equilibrium real wage and employment are determined by the interaction of an upward-sloping wage-setting (WS) curve and a horizontal price-setting (PS) curve, consider the introduction of a new government policy that significantly increases the value and duration of unemployment benefits. Which of the following correctly describes the resulting change in the model's equilibrium?

The WS-PS Equilibrium as a Nash Equilibrium
Consider two competing firms, Firm A and Firm B, who must simultaneously decide whether to set a 'High Price' or a 'Low Price' for their identical products. The table below shows the profits (in thousands of dollars) for each firm based on their decisions. The first number in each cell is Firm A's profit, and the second is Firm B's profit.
Firm B: High Price Firm B: Low Price Firm A: High Price (10, 10) (2, 15) Firm A: Low Price (15, 2) (5, 5) Which of the following statements accurately identifies the stable outcome of this interaction and provides the correct reasoning?

Environmental Policy Dilemma
In a strategic interaction, an outcome is considered a Nash Equilibrium if, and only if, it represents the single best possible payoff for every individual player.
Two competing tech companies, InnovateCorp and TechGiant, are deciding whether to invest in a new, risky technology ('Invest') or stick with their current technology ('Don't Invest'). The table below shows the potential profits (in millions) for each company based on their simultaneous decisions. The first number in each cell represents InnovateCorp's profit, and the second represents TechGiant's profit.
TechGiant: Invest TechGiant: Don't Invest InnovateCorp: Invest (5, 5) (10, 1) InnovateCorp: Don't Invest (1, 10) (8, 8) Analyze each of the four possible outcomes and match it with the correct description.

Analyzing Strategic Decisions
In a strategic game between two firms, Firm A and Firm B, consider the outcome where Firm A chooses 'High Price' and Firm B chooses 'Low Price'. If, from this position, Firm A could increase its profit by switching to 'Low Price' (while Firm B's choice remains unchanged), then the outcome ('High Price', 'Low Price') constitutes a Nash Equilibrium.
Two technology firms, Innovate Corp and Future Tech, are simultaneously deciding which of two new software platforms, 'Helios' or 'Apollo', to adopt. Their success depends on which platform becomes the industry standard. The payoff matrix below shows the profits for each firm (Innovate Corp, Future Tech) based on their choices. Analyze the matrix to identify all the stable outcomes where neither firm has an incentive to change its decision on its own.
Constructing a Strategic Game
Match each game theory term to its correct description based on the principles of strategic interaction.
