- Which one of the following statements is true? In the pre-Keynesian era, prices were assumed not to fully adjust. In the Keynesian model diagram, prices are fixed. GDP is a value of goods and services domestically produced in a country at a given point in time. Say's Law says that demand creates its own production. In the IS/LM model, the interest rate is a function of investment.Explain what tendency does consumption smoothing refer to and why is it assumed in an intertemporal model?In the IS curve model, the consumer demand can be represented by the following equation: C = a + B(YT) where C is consumption, Y is gross domestic product and T are taxes. Which of the following hold(s) ? Select one or more: a.The value of ß can be any number greater than 0 b. If household income increases by 1, consumption increases by C.The value of a can be any number greater than 0 d. a represents consumption required to survive e. Ca represents consumption for leisure f. According to the equation, the interest rate can influence consumer demand
- E. Is unemployment rate a determinant of the murder rate in this data? Answer "YES" or "NO"______________. F. Is the treatment effect statistically significant at the 95% confidence level? That is, did removing the assault weapons ban have a statistically significant effect on the murder rate? Hint: Think about which coefficient we care about in a diff-in-diff set up. Answer "YES" or "NO"._____________. G. Does running this as a two-way fixed effects model make sense? Answer by inputting the number that is associated with the correct statement:______________.Consider Ricardian model with two countries, Home and Foreign, and three goods: Cloth, Food and Books. Labor is the only factor of production. Cloth and Food are freely traded between countries, whereas Books are non-tradable. Unit labor requirements in the Home country are 12 for Cloth, 3 for Food and 4 for Books. Unit labor requirements in the Foreign country are 2 for Cloth, 2 for Food and 3 for Books. The total amount of labor in the Home country is 1500, and the total amount of labor in the foreign is 1000. If the world price of Cloth is 18 and the world price of Food is 12, what is the price of Books in the Home country? [Insert the nearest integer.]We have an economy with two major sectors: Sector I produces the means of production, and Sector II produces the means of consumption. The constant capital advanced in Sectors I and II are $20 billion and $30 billion, respectively. Assume that the variable capital advanced in Sectors I and II are $20 billion and $10 billion, respectively. Also assume that the rate of surplus value is 100% in each sector. Is the economy balanced or will a macroeconomic crisis occur due to the un-coordination between the two sectors? Explain with reference to the numerical values in this example.
- The Keynesian cross model is derived assuming that the interest rate is constant. True or FalseConsider the ISLM model. If the government and central bank used a combination of expansionary fiscal policy and expansionary monetary policy, which of the following would occur? (a) There would be a rise in equilibrium national income and a fall in the equilibrium rate of interest. (b) There would be a fall in equilibrium national income and a fall in the equilibrium rate of interest. (c) There would be a rise in equilibrium national income and an unknown effect on interest rates. (d) There would be a fall in equilibrium national income and a rise in the equilibrium rate of interest.Macroeconomic forecasts from different computer models are usually Very different because the models are based on different data sets, different assumptions, and different macroeconomic theories. Very similar because the models use the same data, and standardized assumptions so it does not matter whether a supply-side economist or a Keynesian economist conducts the research. Very similar because the models must conform to high government regulatory standards. About the same because political objectives never conflict with good economic policies. Very different because it is impossible to determine who funded the research.
- Assuming that there is no government spending or trade, an economy’s GDP is the sum of domestic consumption C and investment I, i.e. Y = C+ I Assume that I is unaffected by GDP Assume the consumption function is C = c0 + c1Y In any equilibrium aggregate demand, AD must be equal to Y, GDP. Given this model, which FIVE of the following statements are correct? Select one or more: A. If the economy above is a demand-driven economy, then the equilibrium solution for Y is given by Y = m(c0 + I), where m = 1/(1 - c1) is the multiplier. B. if c1 = 0.8 the multiplier is equal to 1/0.8= 1.25 C. if c1 = 0.75 the multiplier is equal to 4 D. assume c0 =100, I=50, c1=0.6. The equilibrium value of Y in a demand-driven economy is 300. E. Assume that Y is initially 400, I is initially 100, and the multiplier is 2.5. I increases by 10%. The multiplier implies that in equilibrium Y will increase by 25%. F. The higher is c1 the larger is the multiplier G. If consumers…. Consider the macroeconomic model of a two-sector economy (i.e. no government or trade) using standard notation. Assume that the consumption function is linear, i.e. of the form: C = a +bY . It is known that when ? = 110, the value of consumption, C , is equal to 160.8, and that when ? = 170, the value of C is 207.6. (a) Determine the consumption function and derive the savings ( S ) function for the model. What is the marginal propensity to consume? (b) Determine the equilibrium level of national income when planned investment ? = 255.In the Macro Model, an increase in the amount of Capital in an economy due to Investment spending Group of answer choices Shifts only the Aggregate Demand Curve Shifts only the Aggregate Supply Curve Shifts only the slope of the Aggregate Supply Curve Shifts both the Aggregate Demand Curve and Aggregate Supply Curve
