Patrick and Lydia are a couple with their daughter Nina, who has just turned 2. They live in Norfolk. Lydia has been working part-time after her maternity leave (20 hours per week) and could carry on doing so until Nina is in primary school. However, Lydia is reconsidering and is looking into going back to a full-time job now rather than in 3 years' time. Patrick is a full-time librarian and works 40 hours per week. Nina currently attends a nursery part-time (25h per week) for 125 per week (paid for all 52 weeks). She would attend nursery full-time for double the price if Lydia took the full- time job (at 40 hours per week). 2.2 Explain which option is more favourable in the short- term and what factors contribute to this being the case (4 marks) 2.3 Using the concept of opportunity cost, identify two factors that might cause Lydia to have a much larger financial loss over her lifetime if she carries on working part- time for another 3 years than if she chooses to move full- time now
