An economy on the balanced growth path experiences a natural disaster. A hurricane destroys
50% of the economy’s population and 75% of its capital stock. Show the path of the following
variables (Note: your answer should consist of a graph of a variable or the log of a variable on
the vertical axis, and time on the horizontal axis) and explain the changes over time to the following variables.
A) Capital and production per worker (k and y)
B) Employment N
C) Capital stock K
D) Output Y

Expert Solution

Considering that there is no other factor in economy which effects output

Output (Y) = Capital Stock (K) X Total Labor (L)

Let us consider before disaster, total capital stock was 100, while total populaion was 200.

So Capital per worker before disaster was 100/200 = 0.5,

After disaster Total Capital stock will be (1-75%) X 100 = 25% X 100 = 25,

After Disaster total population will be (1-50%) X 200 = 50% X 200 = 100

So Capital Pre worker will be 25/ 100 = 0.25

Same way production per worker will get lower from 0.5 to .0.25 as capital and labor are only two factors responsible for production.

Employment (N): Since population has become half, competition for employment also becomes half. So employment rate must get doubled

Capital Stock: Since, 75% of capital stock is destroyed, it will become 1/4th

Output: Population is halved and capital stock has become 1/4th, then output will become 1/8th

Following are charts:

In the event of a natural disaster such as Hurricane Matthew in 2016 or Hurricane Katrina in 2005, identify and explain which two specialized fields of toxicology would be most involved in assessing the health risks and environmental issues involved in the aftermath of the storms. What do you think their main role would be?

Consider this type of growth: On balanced growth path, an economy grows at 1.8% a year. 0.8% comes from population growth and 1% comes from technology improvement. What are the rates of change of the variables? 1. Number of workers? 2. Rate of depreciation? 3. Output per worker? 4. Volume of capital? 5. Savings rate?

Consider an economy in steady state (or on a “balanced growth path”)without population growth. Suppose that a mysterious new disease (COVID-19) suddenly kills half of the population. We are interested in the effect this likely has on kapital and output per person , both in the short and the long run. How will this affect in the Solow-model? Show with a graph

Assume that a natural disaster destroys half of a country’s gold stock. Use the formal gold standard model from lectures to trace through the short and long-term impacts on key economic variables of this shock. Make sure to clearly label diagrams and describe the full price-specie flow mechanism.

Begin again with the initial equilibrium. Assume now that a natural disaster destroys a factory where this product is produced. Will the immediate impact be on the demand curve or on the supply curve? Which way will the curve shift (left or right)? Will the new equilibrium price be (higher or lower)? Will the new equilibrium quantity be (higher or lower)? Consider again the situation in part c in which a natural disaster occurs. If this is a competitive market,...

A natural disaster strikes Wakanda and destroys a considerable amount of capital stock. Government officials believe this destruction will reduce national GDP and they should try to prevent this by increasing government spending. They hire you to make a recommendation. a)With the aid of labour and output market diagrams, explain what would be the effects of the natural disaster on the economy. Is it reasonable that the government increases spending? b)Illustrate, with the aid of diagrams again, what would be...

Suppose the US experiences a natural disaster in which a tornado passes through most of the country. This tornado ended up destroying the infrastructure of some highways, factories, and houses across the nation. Unfortunately, 5% of the population did not survive. Assuming the production function is Y = A K 0.3 N 0.7, respond to the following questions: Part 1: Given this natural disaster, how would the factors of production included in the production function above be impacted? Would total...

1) Consider a small, open economy starting off with balanced trade. If the economy experiences an increase in demand for economic investment, the result will be _____________ in the world real interest rate and the introduction of a trade _________. a. no change; deficit b. an increase; surplus c. no change; surplus d. a decrease; deficit 2) Consider a small, open economy that starts off in balanced trade. If its government raises taxes for fiscal policy, we expect to see...

Andalucia experiences severe storms which destroys its main resource, oil rigs. Assume that the Andalucian economy was in long-run equilibrium before this shock happens. a. Use the aggregate demand–aggregate supply model to illustrate graphically the short-run and long-run impact of this supply shock on output and prices. In other word how does the economy get back to long run? Be sure to label: i. the axes; ii. the curves; iii. the initial equilibrium values; iv. the direction the curves shift;...

According to the balanced growth path implied by Solow-Romer model, what parameters are more susceptible to change in response to covid-19(please explain with the formula), in what way, and what would be the effect on the balanced growth path? What would the effect on the output gap and inflation be?
