This essay applies six of N. Gregory Mankiw's foundational economic principles to the decision of purchasing a home, particularly during a recession or economic downturn. The paper examines trade-offs, opportunity costs, marginal thinking, incentives, market organization, and government intervention as they relate to first-time homebuyers. It also considers practical factors such as credit ratings, mortgage structures, and foreclosure opportunities, arguing that an economic downturn can actually represent an ideal buyer's market when approached with discipline and rational decision-making.
During difficult economic times, buying a house is a risky decision. Purchasing a home, particularly for the first time, has always been so — but uncertain financial periods, characterized by downturns followed by possible upturns, make it all the harder. Few prospective buyers are aware of the complex decisions surrounding a purchase, nor are they familiar with the economic details involved. Applying foundational economic principles may make the process somewhat easier, and that is the purpose of this essay.
According to N. Gregory Mankiw (2006), an American macroeconomist, ten fiscal principles underlie economic decision-making. Following these principles can increase profitability while reducing the risk of financial loss. Six of those principles are particularly relevant to home buying: (1) people face trade-offs; (2) the cost of something is what you give up to get it; (3) rational people think at the margin; (4) people respond to incentives; (5) markets are usually a good way to organize economic activity; and (6) governments can sometimes improve market outcomes.
The principle of trade-offs holds that every economic decision requires sacrificing something in order to gain something else. Buying a home involves evaluating whether that sacrifice is worthwhile — namely, whether purchasing the home matters more to the individual than what must be given up.
Elements of trade-off in home buying include location (buyers may be constrained to purchase in a less preferred area due to lower costs), privacy (those who choose urban living renounce a degree of privacy), the type of residence (houses, apartments, and townhouses each affect lifestyle, resale value, and monthly finances), and price (what a buyer must renounce depends on how much they can afford) (Fontinelle, 2010).
Opportunity costs must be sacrificed in order to purchase a home. A buyer might, for instance, need to shop at discount stores for an extended period rather than at upscale retailers, cut down on food costs, and generally scale back their budget considerably. Every financial choice inevitably entails denying one or more expenditures for the sake of another. A person who elects to buy a house and, in doing so, drastically reduces spending on entertainment, food, and clothing is trading those implicit costs for the ability to cover a mortgage.
It is crucial that the individual account for all opportunity costs before committing to a purchase, since assessing them is fundamental to understanding the true cost of any intended action. Ignoring opportunity costs can drive a prospective homeowner into serious debt. Thorough assessment of all costs, along with the discipline to follow through, is essential to a sound decision to acquire a home.
"Small incremental changes help buyers afford a home"
"Recessions, programs, and policy create strong buyer incentives"
Finally, in order to secure the best mortgage rates, most would-be homebuyers need solid credit ratings, a reasonable down payment, and documented income verification. Job security is essential. Buyers should carefully consider that they are purchasing a home they intend to live in for at least three to five years — not making an impulsive investment they may later regret. A buyer's monthly housing payment should not exceed 35% of gross monthly household income. Kenneth Rosen, chairman of the Fisher Center for Real Estate and Urban Economics at the University of California, Berkeley, suggests that buyers targeting low interest rates should consider a 30-year, fixed-rate mortgage. Buyers are also advised to negotiate actively and to examine foreclosures carefully, as these may represent their strongest market opportunities (Mullins, 2009).
Homeownership provides significant economic benefits, serving as a forced-savings program that allows people to leverage their incomes and build wealth. Homeownership "provides financial security for families," former H.U.D. Secretary Mel Martinez has said, "and it generates economic strength that fuels the entire nation" (Surowiecki, 2008).
Purchasing a home is always a consequential decision, and this is precisely where economic principles — trade-offs, opportunity cost, and marginal thinking — prove their value. Buying during an economic downturn is often the most propitious time to do so, particularly given the abundance of incentives available. However, other economic considerations remain critical: specifically, whether one can afford to buy the home now, whether one can sustain its ongoing costs, and whether those financial obligations will not become unmanageable over time. The decision should never be made impulsively. Rather, applying Mankiw's principles carefully before committing to such a significant and long-term responsibility is the soundest approach a prospective buyer can take.
