what is intertemporal choice 
intertemporal choice is an economic term describing how current decisions affect what options become available in the future theoretically by not consuming today consumption levels could increase significantly in the future and vice versa understanding intertemporal choicemany of the choices we make have consequences for the future for instance deciding how much money to spend in the present and how much to squirrel away can greatly impact our quality of life both now and in the years ahead for companies various investment decisions involve intertemporal choice for individuals on the other hand decisions made in the near term that can affect future financial opportunities relate mostly to saving and retirement an individual who saves today consumes less causing their current utility to decline over time the savings grow increasing the number of goods the individual can consume and therefore the person s future utility most individuals tend to be limited by budget constraints that prevent them from consuming to the extent of their desires nevertheless behavioral finance theorists generally find that present bias is common suggesting that people prefer to spend now regardless of the impact it might have in later years it is common for people to make intertemporal choices that accommodate near term needs and wants over long term objectives intertemporal choice exampleif an individual makes an exorbitant purchase such as paying for an around the world vacation that exceeds their usual budget and requires additional financing to cover this could have a substantial impact on the person s long term wealth the individual might take out a personal loan max out credit cards or when possible even withdraw funds from retirement accounts in order to cover the expense making such a choice would reduce the assets the individual has available to continue to save for retirement the person may have to fund supplemental forms of income to augment their salary to compensate for the decline in assets this could be further exacerbated if unforeseen events affect current income a sudden loss of employment for example would make it difficult to recoup recent expenses and set aside funds for retirement if a consumer made a sizable purchase and then was laid off their intertemporal choices combined with those external factors stand to change their future opportunities perhaps the individual planned to retire by a certain age or was on track to finish paying off a mortgage the shortfall in assets could mean postponing retirement or taking out a second mortgage to help deal with the more immediate issues other types of intertemporal choicedecisions on employment can also factor into intertemporal choices a professional might be presented with two job opportunities with salaries that vary depending on the intensity and demands of the role one position may be high stress with long hours required the compensation might also be higher than what is standard for such a position as an intertemporal choice taking such a job might allow for more options on later pension plans conversely taking the job that offers a lower salary but a better work life balance may mean having fewer retirement options with less funding available
