Capitalism: A Progression from the Barter System

Imagine a scenario where Paul Romer, an economist, lives in New York City. Paul wants to buy a shirt, but the producer, Varna, operates in Dhaka, Bangladesh. If Paul were to buy the shirt directly, it would only cost him $3, but the sheer complexity and expense of travel would exceed the item's value by over 700 times. Barter, a system where goods and services are exchanged for other goods and services without the use of money, is inherently impractical in scenarios like this due to the high transaction costs.

The Inefficiency of Barter

To explain why barter is rarely used, consider that for Paul to exchange a face cream tube for the shirt, a double coincidence of wants must occur. Both Varna and Paul must want each other’s goods, and they must be able to physically swap them. However, the transaction cost—mainly in the form of travel costs—makes this process prohibitively expensive. In such cases, barter fails to be a viable solution.

The Emergence of Capitalism

Enter Walmart, a capitalist entity that changes the equation. Walmart buys millions of shirts and ships them to Paul, who can now purchase the shirt for $20 from a store in his neighborhood. Walmart reduces the transaction cost from $2100 to nearly $17 by serving as the intermediary. This is why Varna sells the shirt to Walmart rather than directly to Paul, and why Paul buys it from Walmart.

The Role of Capitalism in Reducing Transaction Costs

Capitalism emerges as a system focused on reducing transaction costs. Capitalists, like Walmart, can significantly lower the cost of transactions by organizing and facilitating trade. This intermediary role is crucial, making it possible to produce goods for strangers and purchase them at prices much lower than their marginal cost. The use of money as an intermediary payment further facilitates the exchange, ensuring that value is ultimately balanced without direct physical trade.

The Importance of Money in Capitalism

Money is essential in capitalism because it serves as the means of intermediation. Without money, the concept of intermediation collapses. The main question then becomes: What real good can an intermediary like Walmart accept as a payment? This highlights the interdependence of money and capitalism. The absence of intermediation renders money meaningless, and vice versa.

The Impact of Reduced Transaction Costs

Reducing transaction costs through capitalism has a profound impact on production and consumption. It enables mass production at scale, making goods affordable for a broader consumer base. For example, a paper mill can produce billions of writing papers, catering to the needs of millions of consumers. Removing the capitalist role would eliminate the incentives for such mass production, leaving both the paper mill and the consumers without the necessary goods.

The revolutionary impact of capitalism on transaction costs is so significant that it challenges human understanding. The extent to which it simplifies production and trade processes makes it a cornerstone of modern economic systems. However, the complexity of this concept often leads to confusion and misunderstanding, making it a challenging but vital aspect of economic theory.
