Question1
Consider the following Solow growth model with technological change and population
growth:
ð‘Œð‘¡ = ð¾ð‘¡
0.4(ð´ð‘¡ð‘ð‘¡)0.6 (1)
ð‘†ð‘¡ = ð‘ ð‘Œð‘¡, 0 < ð‘ < 1 (2)
ð¾ð‘¡+1 = (1 − ð›¿)ð¾ð‘¡ + ð¼ð‘¡ (3)
ð‘ð‘¡+1
ð‘ð‘¡
= 1 + ð‘”ð‘, ð‘”ð‘ = 0.01 (4)
ð´ð‘¡+1
ð´ð‘¡
= 1 + ð‘”ð´, ð‘”ð´ = 0.02. (5)
a) Explain in words what each of these equations means or describes.
b) Write down the goods market equilibrium condition for the model.
c) Combine the goods market equilibrium condition with equations (1) through (3) to find
an equation that describes the change in the capital stock between dates t and t+1 in terms
of the levels of inputs to production at date t. Explain in words what determines this change
over time; whether it is positive or negative or zero.
d) Now take each variable in the model and divide it by ð´ð‘¡ð‘ð‘¡. Use these transformed
variables to re-express the equation you derived in c) as an equation that describes the
change in the capital stock per effective worker between dates t and t+1. Explain in words
what determines this change over time; whether it is positive or negative or zero.
e) Define and describe in words a long-run, steady state equilibrium of this economy.
Depict a long-run, steady state equilibrium in a diagram and label the diagram carefully.
What condition on the equation that you derived in d) would measure or capture this
steady state?
f) In the steady state equilibrium, what will be the numerical values of the growth rates of
aggregate output, the aggregate capital stock, aggregate investment, and aggregate savings?
What will be the numerical values of the growth rate of output per worker, and capital per
worker? What will be the numerical values of the growth rate of output per effective labor
unit and capital per effective labor unit?
g) What would be the qualitative impact of an increase in s for the steady state level of
capital per effective worker and output per effective worker? Show this in a diagram. What
would be the qualitative impact of an increase in s for the steady state growth rates of
output, capital, savings and investment?
h) Now compute the effects for steady state capital and output per effective worker of an
increase in s from 0.1 to 0.2 when the depreciation rate is 0.1. How do these effects differ
quantitatively from the example that we studied in class in which ð‘Œð‘¡ = ð¾ð‘¡
0.5(ð´ð‘¡ð‘ð‘¡)0.5 when
we increased s from 0.1 to 0.2?
i) Compute the value of capital per effective worker over time, for at least 10 years,
resulting from an increase in s from 0.1 to 0.2, starting from an initial steady state at date 0
to a new steady state. Roughly how long do you think it would take to get “very close” to
the new steady state?
j) What is the numerical value of the savings rate, s, that maximizes steady state
consumption per effective worker – the Golden Rule savings rate?
k) What is the quantitative impact for the steady state levels of capital and output per
effective worker of an increase in the growth rate of technological progress from 0.2 to 0.3?
What is the quantitative impact for the steady state growth rates of capital and output per
effective worker of an increase in the growth rate of technological progress from 0.2 to 0.3?
What is the quantitative impact for the steady state growth rate of capital and output per
worker of an increase in the rate of technological progress from 0.2 to 0.3?
l) How could a government raise the rate of technological progress?
Question2
Now suppose that the production function is given by
ð‘Œð‘¡ = ð¾ð‘¡
0.2(ð´ð‘¡ð‘ð‘¡)0.8. (1’)
How does this affect your answers to Question 1 parts h), i), j), and k)? Does the different
production function change any of your other answers to Question 1?
Question3
Assume the Cobb-Douglas production function (1) determines aggregate real GDP.
a) Derive a “growth rate” version of (1) which shows how the growth rate of real GDP
is determined by the growth rates of technology, employment, and capital.
b) Now collect at least ten years of annual data on:
Real GDP (https://fred.stlouisfed.org/series/GDPCA allows download into excel
file)
Employment (https://fred.stlouisfed.org/series/B4701C0A222NBEA
allows download into excel file)
Capital (https://fred.stlouisfed.org/series/RKNANPUSA666NRUG allows download
into excel file).
c) Compute the annual growth rate of each of the data series you downloaded or
otherwise collected in b). Compute the implied annual growth rate of technology at
each date. Now compute the sample average annual growth rates of all four
d) Using the equation you derived in a), and your results in c), what fraction of real
GDP annual average growth over your sample period is accounted for by i) capital
growth, ii) employment growth, and iii) technological change.

I was really unsure about using the forms and classes in visual basic programming language when I came across HwA. The visual basic assignment expert here has deep insight and knowledge and I think as they are professional involved in visual basic programming, they tend to solve the assignments much more accurately and that too in no time.
I am pursuing my masters in finance management from one of the leading buisness schools in London. Even though I have a clear idea of most of the concepts of finance from my undergraduate days, I was still looking for some guidance and help with my finance homework. I had benefitted greatly during my undergraduate days from the online finance tutor at HelpWithAssignment so I decided to contact them again and since then have not looked back. I have been getting finance assignment help and they have helped me a lot
I am extremely satisfied with the Visual C++ programming assignment help that I have received from HwA. The professor was very impressed with the quality of documentation and the grades speak for themselves.
The process capability assignment expert at HwA has helped me not only to write my assignment but also to better understand the theorem and ideas. This has helped me to solve the process capability analysis questions in exams and term papers accurately and get top grades.
I had no clue about how to write a qualitative research paper on Faulkner and so I approached HelpwithAssignment.com. I was also not sure whether they could help me or not but to my surprise they started asking the right kind of questions to me. When I clarified them with my professor, she was impressed and told me that I understood the concept of a research paper. The rest of it was a walk in the park. With my professor’s inputs they provided an excellent research paper and help me get an A

this is a very good website
I have 50 questions for the same test your page is showing only 28
hi can you please help or guide me to answer my assignments. thanks
hi can anyone help or guide me to my assignments. thanks
This solution is perfect ...thanks
Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
