David is curious about the effects of housing wealth on household consumption. Now hehas the China Family Panel Study dataset. In this dataset, respondents are asked to reporttheir housing wealth and monthly consumption.(2) In May 2006, China issued a policy to lower the percentage of down payment forpurchasing units with floor areas less than or equal to 90 m² from 30% to 20%. It causeda higher demand and thus a higher price for houses smaller than 90 m². How can Daviduse this policy to identify the effect of housing wealth on consumption? Please stateclearly about the identification strategy can be used and its logic.(3) In terms of the identification strategy you provide in the above question (2), what is theassumption to make sure that it is valid? How would you test the assumption(s)?(4) What is the limitation of this empirical strategy?

In this problem, David is interested in studying the impact of housing wealth on household…

QUESTION 3: Mr. Daily moves to a new province and has the option to either use prepaid electricity or metered electricity. He requests a comprehensive summary of the costs per kWh of electricity consumed and decides to analyse the information received. He summarizes it in the table below. Use the information to provide answers to Mr. Daily's questions below. Metered electricity A service fee of R115.20 per month is charged for metered electricity (VAT excluded). Electricity is charged at RO.80 per kWh. Prepaid electricity No service fee is charged for prepaid electricity. Electricity is charged at R1.20 per kWh. The first 100 units are free. Cost ( Prepaid elec) Cost ( Metered elec) = R115.20 + R0.80 × (number of units used – free units) —D R1.20 x питber of units used

The Big Mac index is a way of measuring Purchasing Power Parity (PPP) between different countries. By diverting the average national Big Mac prices to U.S. dollars, the same goods can be informally compared. The Big Mac can also be a good indicator for the individual purchasing power of an economy since he exists worldwide in standard size, composition and quality. Price # of Countries Rel. f.

Suppose that you estimate a model of house prices to determine the impact of having beach frontage on the value of a house.14 You do some research, and you decide to use the size of the lot instead of the size of the house for a number of theoretical and data availability rea- sons. Your results (standard errors in parentheses) are: PRICE; = 40 + 35.0 LOT¡ – 2.0 AGE; + 10.0 BED; – 4.0 FIRE; (1.0) (5.0) (10.0) (4.0) (10) N = 30 R2 =.63 where: PRICE¡ =the price of the th house (in thousands of dollars) =the size of the lot of the th house (in thousands of square feet) = the age of the th house in years =the number of bedrooms in the th house =a qualitative/dummy variable for a fireplace (1 = yes for the th house) LOT; AGE; BED; FIRE; a. You expect the variables LOT and BED to have positive coefficients. Create and test the appropriate hypotheses to evaluate these expectations at the 5-percent level. b. You expect AGE to have a negative coefficient. Create and test the appropriate…
