Real World Application: Market Structure & Contestability in Singapore’s Political Scene

When JC A-Level Economics and IB Economics students write essays on Market Structure, they typically rely on standard examples: telecommunications, utility companies, or tech giants. However, to truly stand out to examiners and score top marks in evaluation (AO4), students must demonstrate the ability to apply economic theories to unconventional, real-world scenarios.

One of the most compelling out-of-the-box applications of Market Dominance, Barriers to Entry, and Contestability is the Singaporean political landscape. By viewing political parties as “firms” and the electorate as the “market,” we can extract brilliant insights into economic efficiency.

Here is how you can apply core Market Structure concepts to this unique context.

1. Monopoly vs. Duopoly: The Dynamic Efficiency Argument

In traditional microeconomic theory, a Monopoly is often heavily criticized for being allocatively and productively inefficient. However, a dominant provider (a monopoly) can be evaluated favorably through the lens of Dynamic Efficiency and Internal Economies of Scale.

Consider the traditional “Duopoly” system seen in the US or the UK (the Two-Party System). In a duopoly, firms engage in fierce, continuous non-price competition—in this case, endless politicking, campaigning, and advertising. From a strict economic standpoint, this heavy marketing expenditure is often a waste of resources that does not increase the actual welfare of the “consumer” (the citizen).

Conversely, a single dominant provider in Singapore avoids these massive, recurring marketing costs. By operating without the constant threat of gridlock, the incumbent can reinvest its “supernormal profits” (political capital and resources) into long-term infrastructure, national stability, and dynamic efficiency, rather than wasting it on short-term competitive friction.

2. The Theory of Contestable Markets

This is arguably the strongest evaluation point for any essay discussing market dominance. The theory of Contestable Markets states that the behavior of a firm is determined not purely by its market share, but by the threat of competition.

Even if an incumbent firm holds an overwhelming market share, it will still behave like a firm in a perfectly competitive market if the market is highly contestable (i.e., if barriers to entry and exit are low).

If we apply this to the election cycle, the incumbent “firm” must remain highly responsive to consumer needs and maintain productive efficiency. If they fail to deliver a high standard of living, they face the risk of a “hit-and-run” entry by opposition parties. Therefore, the mere threat of contestability forces a dominant provider to self-regulate and perform efficiently.

3. Analyzing Artificial Barriers to Entry

To maintain monopoly power and deter new entrants, dominant firms often erect Barriers to Entry. In a traditional market, this might take the form of aggressive patenting, predatory pricing, or brand proliferation.

In our non-traditional case study, we can observe structural barriers that mimic economic barriers to entry. For example, the Group Representation Constituency (GRC) system—where parties must field a team of candidates rather than a single individual—acts as a massive “start-up cost.”

For smaller “firms” (minority or newer political parties), amassing the resources, talent, and capital to contest a GRC is incredibly difficult. Furthermore, the redrawing of electoral boundaries can be compared to a firm constantly shifting its product standards to make it legally or structurally difficult for new entrants to gain a foothold.

4. Is Singapore a “Natural Monopoly”?

A Natural Monopoly occurs when it is most efficient for a single firm to supply the entire market due to massive economies of scale. This happens when the firm’s Long-Run Average Cost ($LRAC$) curve continuously falls over the entire range of market demand.

Given Singapore’s exceptionally small “domestic market” (a small geographical size and population), we can argue that the nation’s political and administrative needs operate as a Natural Monopoly.

The market may only reach its Minimum Efficient Scale (MES) when one dominant provider oversees the entire population. If the market were fragmented among multiple providers (a multi-party coalition government), it could lead to a duplication of resources, disjointed national planning, and a devastating loss of the internal economies of scale necessary to run a highly efficient, constrained city-state.

Summary for Exam Application

When evaluating Market Structure essays, use this case study to show examiners that:

• Natural Monopolies are often the most productively efficient outcome in markets with very small domestic demand.
• Monopolies are not strictly inefficient if they benefit from massive economies of scale and avoid wasteful non-price competition.
• High market share does not mean complacency if the market remains contestable.
