$26,250.00
Last year, an economy had 1m registered unemployed and a labour force of 20m. Official statistics forecast a level of unemployment of 0.8m by the year's end while the size of the labour force remains unchanged. If this happens then the unemployment rate will have:
Fallen from 5 per cent to 4 per cent.
(The Economy Question 18.9, modified) Figure 18.21 is the long-run labour market model for the US as a result of specialization according to its comparative advantage. The US has a comparative advantage in the production of capital-intensive aircraft, while China, its trade partner, has a comparative advantage in the production of labour-intensive consumer electronics. Before trade, the German labour market equilibrium is at A. Which of the following statements are correct?
With lower unemployment, workers demand higher wages for high effort, resulting in a higher price-setting curve.
Which of the following statements regarding inequality in the labour market is likely to be true?
Workers in the primary labour market generally experience better working conditions than those in the secondary labour market.
In an imaginary economy, GDP falls from $100bn to $95bn while output per worker rises from $5000 to $5020. In this economy there has been:

We have seen that a gap can exist between the price of a good in its country of production and in the country where it is finally purchased. Price gaps can also exist between the same asset in different countries. Why is arbitrage so much more successful now in eliminating these gaps than it was in the early nineteenth century?
Information about price anomalies is much more widely available today and transactions can be carried out instantaneously. In the early nineteenth century, information was scarce and transactions were slow.

Shift the feasible consumption frontier to the right of the feasible production frontier.
Which of the following statements regarding segmented labour markets are correct?
The 'gig economy' is not part of the primary labour market.

Unemployment is a stock. The size of that stock will increase if:
The rate of job destruction is 2 per cent per year and the rate of job creation is 1 per cent per year.
The price gap reflects the cost of trade between two countries. Assume that the costs of trade are falling over time, ceteris paribus. In these circumstances we would expect to see:

The value of goods and services exported and imported, together with net earnings from overseas assets acquired in the past.
Sections 16.8 and 16.9 argue that institutional arrangements are an important influence on economic performance. Which of the following is given as an example of favourable institutional change?
UK policy to increase competition in the labour market, 1980-90.
Wealth is usually more unequally distributed than earnings, which in turn are more unequally distributed than disposable income. This is mainly because:
Wealth is accumulated savings. Some of this is accumulated by several generations and then passed from parents to children. Earnings are more equally distributed because there is no cumulative effect. Disposable income is more equally distributed still since many governments operate a 'progressive' tax system.
Figure 19.1 shows the inequality in wealth, earnings, and disposable income in the US, Sweden, and Japan using the Gini coefficient. Based on this information, which of the following statements are correct?
Wealth is much more unequally distributed than earnings in all three countries. Sweden attains its relatively equal disposable income distribution through its system of taxes and transfers.
