Assumption of Zero Inflation in the Intertemporal Choice Model
The intertemporal choice model assumes a stable price level, meaning there is zero inflation. This simplifying assumption ensures that money retains its purchasing power over time; for example, $100 can buy the same quantity of goods in the present as it can in the future.

An individual initially chooses to be a saver, meaning they consume less than their income in the present to consume more in the future. If the interest rate increases, what is the definitive effect on their situation, assuming consumption in both periods is a normal good?
Consumption Decision Over Time
Optimal Intertemporal Consumption Choice
Consider an individual who is a borrower, choosing how to allocate consumption between a present period and a future period. If the interest rate they face for borrowing decreases, this individual will unambiguously be made better off.
Arrange the following steps in the correct order to determine an individual's optimal intertemporal consumption choice within the intertemporal choice model.
Match each component of the standard intertemporal choice graph with its correct economic description. The graph's horizontal axis represents 'Consumption Now' and the vertical axis represents 'Consumption Later'.
Analysis of Intertemporal Preferences and Constraints
In a model of choice between consumption now and consumption later, the feasible frontier illustrates all possible combinations of consumption an individual can afford. If the interest rate for borrowing and saving is 8%, the opportunity cost of consuming one additional dollar today is giving up $____ of consumption in the future.
Calculating Maximum Present Consumption
Consider an individual whose income is the same in the present period as it is in the future period. This combination of incomes, where they neither borrow nor lend, is their 'endowment point'. The market allows them to borrow or save at a given interest rate, which defines their feasible consumption possibilities. If this individual's optimal choice involves consuming more in the present than their current income, what must be true about their preferences when evaluated at their endowment point?

An individual is deciding whether to spend $100 today or save it for one year. In a simplified economic model, it is often assumed that the general price level is constant, meaning the $100 would buy the same amount of goods next year as it does today. How would the future purchasing power of this $100 be affected if, instead, the general price level is expected to increase by 5% over the next year and the money is simply held as cash?

Analyzing a Savings Model Assumption
Analyzing a Savings Model Assumption
In an economic model where the general price level is assumed to be constant over time, the main incentive for an individual to save money rather than spend it immediately is to guard against a decrease in the future value of that money.
The Role of a Stable Price Assumption in Economic Models
The Purpose of a Stable Price Assumption
An economic model analyzing an individual's choice between spending and saving assumes that the general price level for all goods and services remains constant over time. Given this specific assumption, what is the sole determinant of whether an individual's saved money will be able to purchase more goods and services in the future than it can today?
An economic model is used to analyze an individual's decision to save or spend $100 over a one-year period. Match each assumption about price changes with its direct consequence on the purchasing power of that $100, if it is held as cash.
An economist is studying household saving behavior in a country that has experienced an average annual price level increase of 10% for the past decade. The economist decides to use a model that assumes the general price level is stable over time. Which of the following statements best evaluates the economist's choice of model?
