Intertemporal budget constraint

The intertemporal budget constraint is a concept in economics that describes how consumers allocate their consumption over different periods of time, typically involving two periods (e.g., today and the future). It reflects the trade-offs consumers face when deciding how much to consume now versus later, given their income and the interest rate. Key elements of the intertemporal budget constraint include: 1. **Income**: Consumers have a certain amount of income in each period.
