A country's current unemployment rate is 11 percent. Economists estimates that its natural rate of unemployment is 6 percent. About how large is this economy's negative GDP gap?

Okun's law indicates that for every 1 percentage point by which the actual unemployment rate exceeds the natural rate, a negative GDP gap of about 2 percent occurs. The actual rate if unemployment exceeds the natural rate of unemployment by 5 percent (= 11-6), which is cyclical unemployment. Using Okun's law, this translates into a 10 percent GDP gap in percentage-point terms (=2 x 5)

Transfer payments are

excluded when calculating GDP because they do not reflect current production.

The determinants of aggregate demand

explain shifts in the aggregate demand curve.

Studies show that

Costs of trade barriers exceed their benefits, creating an efficiency loss for society

Assume the following for the town of Boone: It has a total population of 40,000 people, of which 4,000 are under 16 years of age or are institutionalized; 5,00 are full-time students who are not employed and are not seeking work; and 30,000 are employed. The rest of the people are out of work but have been actively seeking work within the past four weeks. What is Boone's unemployment rate?

Take total population (40,000) minus persons 16 years of age or younger who are not institutions (4,000) minus full-time students who are not working or seeking employment (5,000). 40,000-4,000-5,000= Labor force of 31,000 To fine the number of unemployed workers, subtract the number of employed workers (30,000) from the labor force (31,000) to obtain 1,000 unemployed workers. Unemployment rate = number of unemployed / labor force = (1,000/31,000) x 100 = 3.2 percent

A recession causes a local factory to lay off 30 workers c. Thousands of bus and truck drivers permanently lose their jobs when driverless-computer-vehicles make human drivers redundant d. Hundreds of New York legal jobs permanently disappear when a lot of legal work gets outsourced to lawyers in India

Suppose that the natural rate of unemployment in a particular year is 5 percent and the actual rate of unemployment is 9 percent. a. Use Okun's law to determine the size of the GDP gap is percentage-point terms b. If the potential GDP is $500 billion in that year, how much output is being forgone because of cynical unemployment?

a. Okun's law indicates that for every 1 percentage point by which the actual unemployment rate exceeds the natural rate, a negative GDP gap of about 2 percent occurs. The actual rate if unemployment exceeds the natural rate of unemployment by 4 percent (= 9-5), which is cyclical unemployment. Using Okun's law, this translates into a 8 percent GDP gap in percentage-point terms (=2 x 4) b. Since potential GDP is $500 billions and we are 8 percent below this amount, the output forgone is $40 billion (=0.08 x $500 billion)

a. What is the size of the labor force? b. What is the official unemployment rate?

a. To find the size of the labor force subtract population under 16 years of age or institutionalized (120) and those not in the labor force (150) from the total population (500). The size of the labor force is 230 (=500-120-150) b. The official unemployment rate is the number of individuals unemployed divided by the labor force converted into percentage form. The unemployment rate is 10% (=(23/230) x 100)
