➤ How does inflation influence GDP measures and the assessment of living standards?
Inflation raises nominal GDP without increasing real output or welfare. Economists use a price index, like the GDP deflator, to convert nominal GDP into real GDP. Real GDP per capita therefore shows changes in actual goods and services per person, isolating true improvements in living standards from price level movements.

➤ Why did economists introduce expectations into the Phillips curve model?
Friedman and Phelps argued that expectations of inflation change the short-run trade-off. If workers and firms expect higher inflation, nominal wage bargaining adjusts and unemployment returns to the natural rate. This led to the expectations-augmented Phillips curve and the concept of NAIRU, explaining why the 1960s inverse relation was unstable.

➤ How does cross-price elasticity explain that outcome?
Cross-price elasticity measures how coal demand responds to wind’s price. For substitutes, the elasticity is positive: a fall in wind price reduces coal demand. A larger elasticity means a bigger drop in coal quantity. Use percentage changes (ΔQ_coal/ΔP_wind). Elasticities differ short-run versus long-run as firms adjust capacity and contracts.

➤ Why do neighbourhood and the built environment matter for health-related lifestyles?
Neighbourhoods affect lifestyles through food availability, walkability, green spaces, air quality, noise, and safety. These physical and social features determine opportunities for exercise, healthy eating, social interaction, and stress exposure. Areas with poor infrastructure often show higher obesity, respiratory disease, and mental health problems, so urban planning and local services play a key preventive role.
