If the consumption function is C = 100 + 0.8Yd, T= 200 and Y = 800, what is savings?

The Montag Family purchased a house in 2020 and expects its value (in thousands of dollars) t years in the future will be well-modeled by the function V(t)=310(1.08). By what percentage does the model predict the house will increase in value each year?

Exercise 4. You are a manager at a certain factory that designs small gadgets. The factory has been quite successful in the past years. Your CEO is wondering whether or not it is a good idea to expand the factory this year. The cost to expand the factory is $1.5M. Doing nothing will result in expected $3M in revenue if the economy stays good and people continue to buy plenty of gadgets, but only $1M in revenue is expected if the economy is bad. On the other hand, expanding the factory carries an expected $6M in revenue if economy is good and $2M if the economy is bad. Assume there is a 40% chance of a good economy and a 60% chance of a bad economy. Also, assume the costs of operating the factory account to $.5M if the factory is expanded and $.3M if not. a. Illustrate a Decision Tree showing these choices. b. What should you do?

3. Supply and demand for loanable funds The following graph shows the market for loanable funds in a closed economy. The upward-sloping orange line represents the supply of loanable funds, and the downward-sloping blue line represents the demand for loanable funds. Supply Demand 100 200 300 400 500 LOANABLE FUNDS (Billions of dollars) A INTEREST RATE (Percent) m 0 0 600

What factors must a company like Tesla consider when forecasting supply and demand?

Suppose that the least amount of goods and services that Jim will consume in a year is $40,000. Jim tends to save $0.30 of every dollar of disposable income that he makes. Use the given line to graph Jim's consumption function for disposable income levels between $0 and $200,000. Move each endpoint to the appropriate spot on the graph.

If the MPC is 0.29 what would be the value of MPS do it fast?

a) A planner in a small, open economy has a utility function U = x1X2 and production takes place according to the production functions Y1 = 10L, – 0.5L Y2 = 10L2 – L The world prices of the goods are p1 10 and p2 5. The total amount of labour %| %3D available in the economy is 5 units. (i) Formulate the Lagrange equation. (ii) Write down the Karush-Khun-Tucker conditions. (iii) Determine a possible solution.

Suppose that there are T periods to maximize over. Show that the intertemporal budget constraint is Ct+2 Yt+2 Yt+1 (1+r) (1+r)² (1 + r)² Ct + Ct+1 (1 + r) + 2+...+ Ct+T+1 (1+r)² \ T = Yt + + +...+ Yt+T+1 (1+r)

The COVID-19 pandemic has caused an unprecedented increase in savings in many countries around the world.  In the EU, the savings rate of households has jumped from 12.5% to 17%.  In 2008-2009, it had moved from 12.5% to 14% (Dossche and Zlatanos 2020).  Even if the source of 2020 surge in savings is different from the one of 2008, it is obvious that this increase does not result in more investment and growth. QUESTION: 1. With reference to the paradox of thrift discuss the appropriate approach by the government to get the economy out of economic downturn swiftly
