Economic analysis of demand elasticity, market dynamics, business mergers, externalities, and market efficiency form the backbone of this comprehensive final exam. The exam evaluates understanding across microeconomic principles—such as demand responsiveness, business organizational structures, and efficiency—as well as macroeconomic concepts like externalities and market external impacts. It combines theoretical knowledge with data analysis, requiring interpretation of graphs and tables, and applies these to real-world examples such as market shortages, production processes, and trade debates.

Understanding demand elasticity is fundamental, as demonstrated by the scenario where a 1% increase in the price of Christmas trees results in a 0.6% decrease in quantity demanded. This signifies that demand is inelastic, meaning consumers are relatively less sensitive to price changes (Mankiw, 2021). Recognizing the elasticity of demand allows businesses and policymakers to predict behavioral responses to price adjustments, impacting revenue, taxation, and subsidy policies (Pindyck & Rubinfeld, 2018).

The headline about a cigar shortage highlights the interaction of supply and demand, specifically indicating a situation where the quantity demanded exceeds supply at the prevailing price. When the price of cigars is too low, consumers want more than producers are willing or able to supply, leading to scarcity. Such situations typically signal the need for a price adjustment or a shift in supply or demand (Varian, 2019). In this case, a shortage results from increased consumer interest, shifting demand outward without a corresponding rise in supply, pushing prices upward or creating shortages if barriers prevent prices from adjusting freely.

Business mergers are a key feature of market structure analysis. When Samsung and Sony partner in a flat-screen manufacturing enterprise, it exemplifies a joint venture—a strategic alliance where two firms combine resources for a specific project without merging entirely (Laudon & Traver, 2020). This scenario differs from horizontal mergers, where firms producing similar products combine, or vertical mergers, involving firms at different stages of production, such as a manufacturer acquiring a supplier. The choice of merger type influences market competition, efficiency, and regulatory scrutiny (Shapiro & Varian, 1999).

Pricing and market equilibrium are critical for understanding how markets function. The concert ticket scenario illustrates the concept of market equilibrium, whereby the equilibrium price of $35 is below the selling price of the tickets, which sell out quickly. The presence of 1,000 still wanting to buy indicates excess demand at that price, implying the market price is below equilibrium, or that prices are being set at a level which clears supply while leaving some demand unmet. In a competitive market, equilibrium is achieved where quantity demanded equals quantity supplied, often at a price where consumers’ willingness to pay matches the sellers’ costs (Mankiw, 2021).

Microeconomics also examines resource allocation efficiency, exemplified by the concept of comparative advantage. When a resource is better suited to produce one good rather than another, it possesses a comparative advantage, making it more efficient in that context (Krugman, Melitz, & Obstfeld, 2018). This principle underpins international trade, where countries specialize according to their comparative advantages, leading to increased overall efficiency and gains from trade.

The graphical demand-supply analysis reveals that increased demand shifts the demand curve from D1 to D2, causing prices to rise from $1.00 to $1.25 per dozen eggs and an increase in the quantity exchanged to 3,000 dozens per week. This illustrates the positive relationship between demand and price, and the market's adjustment to new demand conditions. The price increase and higher quantity exchanged reflect market responsiveness and the law of demand (Varian, 2019).

Market structures such as oligopoly have characteristics that influence economic innovation. An oligopoly, characterized by few large firms, tends to be conducive to technological change due to the significant profits and market power these firms possess, which provide incentives for research and development (Chen & Reitz, 2015). This market dynamic differs from perfectly competitive markets, where the profit motive is less pronounced and innovation is driven more by competition on price than on technological advancement.

The concepts of marginal productivity and diminishing returns are central to production theory. Diminishing marginal productivity begins when the additional output produced by the addition of one more worker starts to decline, indicating the optimal number of workers has been exceeded. For example, if the table shows diminishing returns after the fourth worker, this reflects the law of diminishing marginal returns, a key principle in efficient resource utilization (Pindyck & Rubinfeld, 2018).

International trade and economic policies often involve debates about job creation and competitiveness. Ross Perot's 1992 campaign argument against free trade with Mexico drew on fears of massive U.S. job losses due to low wages abroad. Economists argue that while some jobs may be lost, overall employment can benefit from increased efficiency, export opportunities, and consumer gains (Krugman et al., 2018). The consensus indicates that free trade creates both winners and losers but generally enhances economic welfare in the long term.

Market analysis includes the decision-making choices of firms, such as profit maximization. A monopolist, when faced with MR

Elasticity of demand is measured at specific points on a demand curve. The point where elasticity is zero corresponds to a perfectly inelastic segment, where quantity demanded does not respond to price changes. This often occurs at the vertical portion of the demand curve. Identifying such points helps understand consumer responsiveness to price changes (Varian, 2019).

Average product, calculated as total output divided by the number of workers employed, reveals productivity levels. When employing eight workers, the average product can be computed from the data table, illustrating the efficiency of labor use and potential productivity improvements (Pindyck & Rubinfeld, 2018).

Environmental policies, such as restrictions on nonrefillable bottles, can serve both environmental and economic protection goals. The EU's argument that Germany's rules shield its beverage makers from international competition reflects that environmental regulations can function as trade barriers—akin to tariffs, quotas, or embargoes—aimed at protecting domestic industries (Snape & Smith, 2019).

The marginal product of labor can be identified from data tables by determining when the additional output corresponds to a specific level—in this case, a marginal product of seven. This is an application of the law of diminishing marginal returns, whose analysis helps firms determine optimal employment levels for maximum productivity (Krugman et al., 2018).

Pricing strategies are based on market structures; in perfect competition, firms produce where price equals marginal cost, leading to allocative efficiency. Hence, the equilibrium price under perfect competition often coincides with the marginal cost, ensuring resources are allocated efficiently, as reflected in the demand and supply graphs (Mankiw, 2021).

Market power and competition influence pricing decisions. In monopolistic competition, a firm maximizes profit by setting a price above marginal cost, typically charging a price where marginal revenue equals marginal cost. The specific price can be determined from the firm's demand curve and profit maximization conditions (Shapiro & Varian, 1999).

The long-run outcome of firms exiting a market when prices fall below their minimum average cost results in a reduction of supply until prices rise again to cover costs. This adjustment ensures firms earn only normal profits, stabilizing the market at a new equilibrium (Krugman et al., 2018).

Externalities, both positive and negative, are market outcomes that spill over onto third parties. Critics argue that government intervention—through regulation, taxation, or subsidies—is necessary to correct externalities. However, effective correction can be complex, and imperfect policies may fail to address externalities adequately (Baumol & Oates, 1988).

Business mergers are characterized by different types depending on the entities involved. When a meat-processing company acquires a large cattle ranch, it exemplifies a vertical merger—integrating different stages of production within the same industry chain (Laudon & Traver, 2020). Conversely, when two retailers in the same industry merge, it is a horizontal merger.

In similar fashion, when a retailer buys out its direct competitor, Vango Golf, the transaction is a horizontal merger, aimed at increasing market power and reducing competition (Shapiro & Varian, 1999). Such mergers influence industry structure, competitive practices, and market efficiency.

Finally, oligopolies are favorable environments for technological innovation due to substantial profits, resources for R&D, and the incentive to maintain competitive advantage. Although high entry barriers and market concentration might seem restrictive, these firms often lead in technological advancements, driven by the need to differentiate themselves and sustain profitability (Chen & Reitz, 2015).
