1. The simulation showed many varying fiscal policy instruments. The ability to control government spending was illustrated by the form for adjusting government expenditures on infrastructure and education. The simulation also allowed for the manipulation of tax policy by varying the income tax rate. These three factors infrastructure expenditures, education expenditures and tax rate were but a condensed and simplified toolset for emulating all the possible fiscal policy decisions that a real government might partake in actual macroeconomic planning scenarios.
Apart from these variables, the simulation also showed several analogues of real world economic data. The simulation showed a simplified overview of the fictional countrys budget, concentrating on the amount of deficit present in the annual budget. Apart from the budget, the inflation rate, unemployment rate and popularity was also tracked by the simulation. These dependent factors would vary according to the decisions made in adjusting the expenditures and income tax in the simulation. Increases in expenditures tended to increase the budget deficit and the inflation rate. On the other hand, increases in expenditure reduced unemployment and increased popularity. Raising income tax increased unemployment and reduced popularity but curtailed inflation the rate as well as helped balance the budget by increasing the cash inflows.
2. An increase in expenditure was reflected on the aggregate demand and supply plot as a rightward shift of the aggregate demand curve. Additionally, the increase in expenditure was also reflected as an increase in GDP. This GDP increase was derived from the multiplier for the expenditure. For the fictional country of Erewhon, the marginal propensity to consume (mpc) is 0.8 which gives a GDP multiplier of 5. This means that an increase of X million in expenditures would correspond to a 5X million increase in GDP.
The GDP increase is seen in the rightward shift of the aggregate demand curve as it intercepts the aggregate supply curve further along the x axis. However, increasing expenditures above a certain point will start to trigger an increase in inflation. This is because when it starts intercepting the aggregate supply curve in its upward sloping path, rightward shifts of the aggregate demand will also produce increasing intercepts along the Price Level axis.
Adjusting the tax rate also has the same effect. Decreasing the income tax also corresponds to rightward shifts of the aggregate demand while increases move the aggregate demand to the left. However, the shifts in aggregate demand are not as pronounced as compared to the shifts produced by expenditures. The effects of income tax are also dictated by the effects of the moving intercept between the aggregate demand and aggregate supply curves.
3. One key point was the difference in the multiplier between income tax and government spending. This fact was clearly demonstrated in the simulation. A 100 million cost towards expenditures would produce a greater shift in demand and a greater increase in GDP as compared to spending the same 100 million in a tax cut effected by reducing the income tax rate. Increasing expenditures by 100 million led to a 500 million increase in GDP. Reducing the government income by the same account through a tax reduction only increased GDP by 400 million.
The simulation also stressed how increases or decreases in expenditures translate to rightward or leftward shifts of the aggregate demand curve. The simulation graphically showed how policy decisions affect the countrys aggregate demand and supply curve. Increases in expenditure shift the demand curve rightward while decreases in expenditure shift the aggregate demand curve to the left.
Another key point emphasized was the relationship between aggregate demand, supply and inflation. The plot clearly demonstrated how shifts in aggregate demand translate to higher GDP and a higher price index.
Another interesting point from the readings which was shown in the simulation was the three-stage shape of the aggregate supply curve which produces a rounded backwards L shape. This reverse rounded L shape is formed by a horizontally flat initial phase, followed by a positively sloped middle phase and ends with a vertically sloped segment. This L shape can be traced back to the law of diminishing returns. At the initial phase, marginal returns are high as the economy has lots of spare production capacity. As such, production can increase without needing price increases. When the production capacity is saturated, the market needs higher and higher prices in order to justify increased production. This makes the path of the aggregate supply curve go asymptotic upwards.
4. One important take away lesson is to be found in the aggregate supply. The workplace can be seen as a miniaturized version of the national economy. The reversed L supply curve tells us that production capacity should be pushed to the limit before inflation can take place. In the workplace, this tells me that keeping the price level constant, the company should produce at its highest possible efficiency until it hits production bottlenecks. In the national economy this situation provides for greatest GDP without inflation. In the workplace, this translates to utilizing all the companys resources for production effectively without resulting in having to charge higher prices for our products.
Another take away lesson from this simulation is a better understanding of current events. This may not translate directly to the workplace as it is quite frankly more useful to me as a person not me as an employee. Fiscal policy is an important issue in governance and it is often the subject of much public discourse. Economists, ideologues, politicians and spin doctors all have their own say on many various politically charged economic issues. By having an understanding of the effects of government fiscal instruments, I as a person would be better prepared in understanding the options available to the government. This can lead to better democratic decision making on my part.
5. For me, the interaction between unemployment and inflation was quite interesting. The simulation clearly showed the dichotomy faced by government as they can only choose to reduce one of the two factors. Efforts to reduce unemployment will tend to increase inflation. On the other hand, efforts to curb inflation tend to increase unemployment levels. This brings to mind the concept of an equilibrium point by which the government shall have to balance an acceptable inflation rate with an acceptable unemployment rate.
Additionally, this exercise also brought out some similarities and differences with microeconomic analysis. One major similarity between the exercise and microeconomics is the usage of the same supply and demand framework. In microeconomics, the framework is used to figure out equilibrium prices and quantities for the exercise the same framework was used to figure out the analogous quantities of price level and GDP. One major difference though was the presence of a multiplier effect. Macroeconomic policy changes have more sweeping effects than microeconomic policy changes not only due to the scope of the problem but also because of the multiplier effect inherent in mapping out an entire economy.
