You are given the following information about a closed economy. There are three sectors: manufacturing,

services, and the public sector (government). In a year, the manufacturing sector

produces goods (comprising capital goods, consumption goods, and intermediate goods) with

market value $150bn and uses up $60bn of intermediate manufactured goods. Firms in the manufacturing

sector pay wages of $60bn and undertake .xed investment of $20bn (buying capital

goods produced by the manufacturing sector). In the service sector, .rms produce $260bn of

services, making no use of intermediate goods. Service-sector .rms pay wages of $140bn and

invest $50bn (buying capital goods). The government directly employs workers paid $50bn in

total, and buys $40bn of services from service-sector .rms.
