The assignment involves analyzing macroeconomic and microeconomic scenarios, including constructing expenditure functions, assessing investment behaviors, analyzing market equilibrium, determining profit-maximizing strategies in both perfect competition and monopoly markets, understanding price discrimination, evaluating firm decisions in monopolistic competition, and interpreting strategic firm behaviors in multiple market entry decisions. Specific tasks include calculating aggregate expenditure functions, equilibrium GDP, impacts of income changes on consumption and imports, market supply and demand analysis, profit determination, market entry and exit analysis, elasticity considerations, effects of product substitution due to changes in broadcast reach, graphical representations of firm costs and revenues, and game-theoretic analysis of firm entry strategies.

This comprehensive economic analysis explores various facets of macroeconomic and microeconomic decision-making. The first part delves into the derivation of the aggregate expenditure (AE) function within an economy, utilizing data such as consumption savings behavior, government spending, taxes, exports, and imports. A critical component involves calculating the equilibrium GDP (Ye) where aggregate demand equals aggregate supply, depicted graphically with all relevant axes, intercepts, and equilibrium points annotated. Understanding the behavioral underpinning that consumers save 25 cents per dollar of additional income informs the slope and intercept of the AE function, which is vital for macroeconomic stabilization policies.

Furthermore, the analysis examines the implications of a predetermined GDP level—specifically 2400 units—on actual versus planned investments within the economy. This entails calculating the planned investment based on the expenditure components and explaining the mechanisms that cause deviations between actual and planned investment, reflecting economic overheating or underperformance. This section emphasizes the importance of investment surprises, expectations, and economic equilibrium adjustments, necessitating clear and precise calculations supported by economic theory.

The third subsection investigates the marginal impact of a one-dollar increase in income on consumption, imports, and domestic goods, establishing the marginal propensities and their effects on aggregate demand-shifting parameters. These relationships are fundamental in understanding fiscal policy effectiveness and the transmission of income changes through an economy's expenditure components.

Transitioning to microeconomics, the analysis addresses a perfectly competitive market scenario with given demand and supply functions. It involves solving for the profit-maximizing price, output, and profit levels for a firm with specified total costs and marginal costs. The solution demonstrates the application of firm-level optimization, equilibrium price determination, and profit calculation, essential concepts for understanding market efficiency and firm behavior.

The discussion proceeds with the effects of market entry or exit, analyzing how long-term industry adjustments influence equilibrium prices and quantities. This involves the analysis of firm profits and losses, entry barriers, and the impact of competition on market supply, setting the groundwork for understanding market dynamics and strategic behavior.

In the case of a monopoly operating in two regional markets, the analysis applies third-degree price discrimination strategies, calculating optimal prices and quantities considering demand elasticities. The assessment interprets demand elasticity implications on pricing strategies, with emphasis on revenue maximization and consumer welfare effects. Additionally, the scenario explores the implications of broadcast exchanges altering market boundaries and questions whether price discrimination remains feasible under such circumstances, considering legal and strategic constraints.

The analysis then shifts to a monopolistically competitive industry, where the firm’s short-run profit maximization involves curves of demand, marginal revenue, marginal cost, and average costs. Drawing these curves with proper labels facilitates understanding firm behavior, with subsequent evaluation of shutdown conditions based on cost and revenue considerations. The transition from short-run to long-run involves industry exit, market clearing, and adjustments in price, output, and economic profits, illustrating market entry and exit dynamics and their effects on firm strategies.

Next, a strategic game-theoretic scenario features firms contemplating entering a new electric vehicle market with potential profit outcomes. Analyzing the firms’ payoffs enables prediction of entry decisions, considering how government subsidies alter incentives and strategic equilibria. This underscores the role of policy interventions in shaping industry structure and firm behavior in oligopolistic settings.

Finally, the examination of a firm in perfect competition assesses the profit-maximizing output level by comparing total costs at different production quantities. The analysis evaluates whether the current production point (10 units) aligns with profit maximization by considering marginal cost and total revenue changes, grounded in firm-level marginal analysis principles. This reinforces understanding of short-run optimization conditions under perfect competition.
