Table 2: The table below provides information about a fictional economy in which the typical consumer’s basket consists of 12 pairs of socks and 4 pairs of gloves.   Refer to table 2. If the consumer purchased the CPI basket, the cost of the basket was lowest in year [word1], with a total value of $[word2]. Under the assumption that the base year is year [word3], the CPI was 90.42 in year 3. If the base year is year 3, CPI in year 2 is [word4] and the CPI inflation rate between year 2 and year 3 is [word5] percent. If the consumer purchased 15 pairs of socks and 2 pairs of gloves in year 3, then the actual cost of basket in year 3 is $[word6] and the change in the cost of the basket the consumer actually purchased between year 2 and year 3 is, therefore, [word7] percent, which evidences that CPI overstated inflation in year 3 by [word8] percentage points. An analysis of the reasons why the consumer decided to purchase a different basket in year 3 suggests that this is due to a change in [word9], which implies that the overstatement of CPI inflation is likely associated with the problem of [word10]. Meanwhile, an increase in the prices of socks and gloves will [word11] since those items are [word12], and will [word13] since those items are [word14].

Figure 1 provides the recent evolution of selected macroeconomic aggregates. Based on our class discussion regarding (i) the importance of distinguishing long-run trend vis-à-vis short-run deviations from trend dynamics; (ii) the current state of the labor market; (iii) the persistent or temporary nature of recent inflation dynamics; and (iv) the level of GDP relative to trend, briefly analyze the current macroeconomic environment using sound economic arguments. To guide your analysis, focus on outlining answers to the following questions (bullet points are perfectly valid): Figure 1: Selected U.S. macroeconomic aggregates (various samples) a. Provide an economic assessment of the cyclical nature of economic activity. In particular, is the economy entering a recession in light of recent/current macroeconomic and political events and the FOMC’s decision to keep the federal funds rate steady yesterday? Answer yes or no and provide a reason why. Relate your answer to the data of figure 1.b. In your opinion, and give the current and expected situation, should the FOMC reduce rates in the May 7th, 2025 meeting? Argue in favor or against and provide a reason using sound economic reasons. Relate your answer to the data of figure 1.

Campaign Expenditure (part 4)   Use the VOTE.DTA data for this question. Consider the following model voteA=β0+β1ln⁡(expendA)+β2ln⁡(expendB)+β3prtystrA+u{“version”:”1.1″,”math”:”voteA = \beta_0 + \beta_1 \ln(expendA) + \beta_2 \ln(expendB) + \beta_3 prtystrA + u”} where voteA is the percentage of the vote received by candidate A, expendA and expendB are the campaign expenditures by candidates A and B respectively, and prtystrA is the percentage of the most recent presidential vote that went to A’s party. Now re-parameterize the model to test the null hypothesis from the previous question, i.e., a 1% increase in candidate A’s expenditure would be exactly offset by a 1% increase in candidate B’s expenditure. Let θ=β1+β2{“version”:”1.1″,”math”:”θ=β1+β2″} The null hypothesis will be:
