explain the regression model more so the results are more clean and visible to answer the papers’ objective

REVISION
PLEASE ADD CONCLUSION AND RECCOMMENDATIONS TO THE PAPER (APPROXIMATELY 2-4 PAGES)

In the methodology section things needs to be more clear it was asked:
– I need all the data to be based on the GDP per capita constant US dollar 2015 and transformed it to ln afterwords to be in percentage to avoid the negative variables to try to reduce the endogeneity
– the equation needs to be more detailed to help with the results section afterwords, the equation is missing to then related it in the results section
– needs a chart to be GDP per capita growth so everything is more clear

In the results
– the model needs to be a lot more clearer
– simplify the first part not needed a lot of words but more clear view of how we will prove the question asked
– needs to have a hausman test for the whole samples to see if we need to use fixed or random effects
– needs to have also a test for the mutliciliniarity and test hetroscidasticity
– explain the regression model more so the results are more clean and visible to answer the papers’ objective

SECTION A
Answer ONLY ONE out of the two questions in this section
QUESTION 1

Present a model of the labour market and use its equilibrium to derive an aggregate supply relation of the form y, = y * +8(p, where 0 < B <1, y, is the level of output, y  is the natural level of output, A is the price level — all measured in natural logs — while is the expectations operator. [12.5%]

Explain the mechanisms that underlie the relation between price level and output in aggregate supply. Illustrate the relation diagrammatically and then show and explain the impact of a reduction in the expected price level. [10%]

“Can a permanent/anticipated change in monetary policy affect output?”

Provide an analysis that addresses this question, by combining the aggregate supply relation, with an aggregate demand relation of the form y, = m, — p,, where m, is the supply of money. [27.5%]
