Analyze the properties of pouches of mackerel used as informal money in federal prisons, assessing how well they satisfy the six properties of ideal money—durable, portable, divisible, uniform quality, low opportunity cost, and stable value. Discuss the reasons why the mackerel economy persists despite efforts to discourage it, and evaluate its effectiveness as a medium of exchange within the prison environment.

Paper For Above instruction

In examining the use of pouches of mackerel as an informal currency within federal prisons, it is essential to analyze how well these items fulfill the six ideal properties of money: durability, portability, divisibility, uniformity, low opportunity cost, and stable value. Each property plays a critical role in determining the effectiveness of an item as a medium of exchange, and understanding their satisfaction by mackerel pouches sheds light on the economic dynamics within the prison system.

Durability

Durability refers to the ability of money to withstand wear and tear over time without losing its value. In the case of mackerel pouches, their physical characteristics make them relatively durable compared to other potential commodities like loose items or small-denomination coins. The plastic and foil packaging of mackerel pouches protect the contents from spoilage and physical degradation, enabling them to maintain their form and function over extended periods despite rough handling or storage in lockers. This durability ensures that mackerel pouches can serve reliably as a medium of exchange within the prison environment, sustaining their utility over time.

Portability

Portability is essential for money to facilitate quick and easy transactions across distances and among individuals. Mackerel pouches are lightweight, compact, and easy to carry, making them highly portable for prisoners engaging in trades, gambling, or service exchanges. The small size allows prisoners to conceal or transport multiple pouches without inconvenience, which enhances their practicality as a medium of exchange. The portability of mackerel pouches significantly contributes to their acceptance among inmates seeking quick and discreet transactions.

Divisibility

Divisibility pertains to the capacity to divide money into smaller units to cater for transactions of varying sizes. While a pouch of mackerel is inherently a whole unit, prisoners often trade or value smaller portions by breaking down the pouch contents or trading smaller quantities of the commodity. This informal subdivision is less precise than modern currency but sufficient for small-scale transactions, such as gambling debts or buying services. Therefore, mackerel pouches fulfill this property adequately within the constraints of their context, supporting flexible trade among inmates.

Uniform Quality

Uniform quality implies consistent standardization, ensuring each unit of money has similar value. In the prison context, the uniformity of mackerel pouches is dictated by their packaging and consistency in size and nominal content from the commissary. Although there may be slight variations, generally, the pouches are standardized at about $1 each, which provides a reasonable level of uniformity for prisoners to accept the mackerel as a stable means of payment in their informal economy.

Low Opportunity Cost

Opportunity cost reflects the value of the next best alternative foregone when choosing to hold or use money as a medium of exchange. For prisoners, the opportunity cost of using mackerel pouches as currency is relatively low, especially given that many do not prefer to eat the mackerel but instead treat it as a tradable commodity. Since the pouches are not typically valued for their nutritional content, their alternative use as food is low, leaving most inmates with little incentive to hoard or discard them solely for consumption. Consequently, the opportunity cost of using mackerel pouches as money is minimal, reinforcing their utility as a medium of exchange.

Stable Value

Stability of value is crucial for money to serve as a reliable store of wealth and unit of account. In the prison economy, the value of mackerel pouches tends to be relatively stable compared to other potential commodities, largely because of the uniform pricing and controlled supply via the commissary system. Although external factors like changes in supply or enforcement policies can influence value, the price of about $1 per pouch remains fairly consistent, giving prisoners confidence in using them as a reliable form of money.

Persistence of the Mackerel Economy and Effectiveness as Money

Despite attempts by wardens to curb the mackerel economy—such as banning cans after refashioning into makeshift weapons or limiting stockpiling—market forces sustain the trade. The strong demand for an accepted medium of exchange incentivizes inmates to find alternative commodities, such as plastic pouches, which are less easily repurposed into weapons but serve the same monetary functions. The willingness of prisoners to circumvent prohibitions illustrates the robustness of informal markets under economic pressures and the importance of money’s functional properties over formal regulations.

The effectiveness of mackerel pouches as money lies in their ability to quickly facilitate smaller exchanges within the prison, particularly in gambling, services, and illicit trades. Their lightweight, durable packaging, coupled with their reasonably stable and consistent value, provides inmates with a practical means to conduct transactions without official currency. Moreover, their use demonstrates how market mechanisms adapt to restrictions, with prisoners transforming commodity items into informal currencies that fulfill the essential functions of money—medium of exchange, unit of account, and store of value—despite their unofficial and fluctuating nature.

Conclusion

In conclusion, pouches of mackerel satisfy most of the six properties of ideal money effectively within the prison environment. They are durable, portable, divisible, relatively uniform in quality, have low opportunity costs, and maintain a stable value. The resilience of the mackerel economy underscores the importance of these properties for functionality, especially in restrictive contexts where official currency is unavailable or banned. The inmates’ ability to sustain this informal monetary system highlights the adaptability of economic behavior under constraints and the core attributes that underpin effective money.
