Homework 3: Chapters 28-29 Name: Class: Date: This assignment relates to following learning outcomes: - calculate real GDP the rate of economic growth, and labor productivity - explain why the trend rate of U.S. productivity growth has increased since the earlier 1973-1995 period - calculate unemployment rate, labor force, GDP and Consumer Price Indexes, nominal and real interest rates Follow the instructions below to complete the assignment. Instructions Once you've watched the video: The Labor Market - The Economic Lowdown Video Series, Episode 4, reviewed website: The Bureau of Labor Statistics of the U.S. Department of Labor (BLS), read Chapter 28: Economic Growth and Chapter 29 . Business Cycles, Unemployment, and Inflation then read following problem(s) and find the solution(s) 1. Suppose that work hours in New Zombie are 200 in year 1 and productivity is $\$ 8$ Suppose that work hours in New Zombie are 200 in year 1 and productivity is $\$ 8$ per hour worked. What is New Zombie's real GDP? If work hours increase to 210 in year 2 and productivity rises to $\$ 10$ per hour, what is New Zombie's rate of economic growth? Explain why sustained long-term economic growth comes from increases in labor productivity. Why do you think the trend rate of U.S. productivity growth has increased since the earlier 1973-1995 period? The quantity of labor and increases in labor productivity are important sources of economic growth. Between 1953 and 2015 , in the US economy the labor force the more significant factor. multiply hours worked by productivity. 2. Suppose that New Zombie has adopted the framemork used by the US Bureau of Labor Statistics to calculate its labor force statistics. Following information is extracted from a database maintained by the country's ministry of labor: {|l|c|} Total population & $24,512,311$ \\ Military personnel & 98,539 \\ People below 16 years of age & $4,240,102$ \\ People in elderly care centers & $1,232,130$ \\ People who didn't look for job in last 4 weeks & 831,304 \\ {l} Housewives whose sole activity is \\ homemaking & $3,424,204$ \\ Volunteers & 313,200 \\ Employed people by private sector & $8,000,690$ \\ {l} Employed people by public sector and state \\ and local government (federal employees are \\ not included) & 715,000 \\ {l} Self-employed people & $3,423,042$ \\ {l} People who are jobless, actively looking for a \\ job, and available for work & $2,234,100$ \\ Calculate the unemployment rate and the labor force of New Zombie. Show your calculation. (See next page for the formula and directions for this problem). To calculate the unemployment rate, you have to use the formula: Unemployment rate $=\#$ of unemployed $ $ labor force $ 100 \%$ Labor Force is calculated using the formula (s) given below Labor Force $=$ Total Civilian Non-Institutional Population - People Who Did not Search for Job in Last 4 Weeks - Volunteers - House wives Total Civilian Non-Institutional Population $=$ Total Population - People Below the Age of 16 yeas - Military Personal - People in Elderly Care Centers The BLS is the Bureau of Labor Statistics, an agency within the Department of Labor. The unemployment rate is calculated by taking a random survey of 60,000 households nationwide. (Note: Households are in the survey for four months, out for eight, back in for nationwide. (Note: Households are in the survey for four months, out for ejght, back in for four, and then out for good. Interviewers use the phone or home visits using laptops.) The population is divided into three groups: Group 1 consists of those under age 16 or institutionalized. In this country, if you are under 16 you are expected to be in school. If you are in an institution such as a nursing home or prison you obviously cannot present yourself to the labor market. Group 2 consists of those "not in labor force". Examples of individuals who are not in the labor force are full-time college students who are not working, stay at home parents, and retirees. Group 3 consists of those age 16 and over who are willing and able to work, and actively seeking work (individuals who have demonstrated job search activity within the last four weeks). So, Group 3 is the labor force. The labor force is simply described as those who are either employed or unemployed. To be counted as unemployed you must be a part of the labor force. The labor force consists of persons 16 years of age or older who are not in institutions and who are employed, or unemployed but seeking employment. The unemployment rate is defined as the percentage of the labor force that is not employed and is found by taking the number of those unemployed and dividing that number by the labor force. Remember to multiply the result by 100 so you can express this as a percentage. The BLS rounds the number to one decimal point. 3

Using Noether's Theorem to identify new symmetries.In lectures, we used continuous symmetries to derive conserved quantities. One way to state Noether'stheorem for general symmetries under generalized coordinate transformations is the following: Suppose theaction S(qa: 4at) is invariant under the following symmetry transformation:qa+%.=4a + ta(2)Then the quantity5aL(gas 4a; t)dib(3)is conserved. So for example, choosing the qa to correspond to the components of position vectors of Nparticles, and choosing the €a to correspond to shifting all particle positions by the same amount in the-direction, we re-derive the conservation of total linear momentum along the z-direction.We can use Noether's theorem to derive conserved quantities that are not just the familiar momenta andenergy.
