11. Consider a competitive market where the demand and the supply depend on the current price ofthe good. Then we can estimate the demand curve byA. fitting a line through the quantity-price outcomes using OLSB. fitting a nonlinear function through the quantity-price outcomes using OLSC. using an instrument that is correlated with price but uncorrelated with the error term inthe demand equation and running two stage least squaresD. using an instrument that is uncorrelated with price but correlated with the error term inthe demand equation and running two stage least squares

A manufacturer produces two models of television stands. The table at the left shows the times (in hours) required for assembling, staining, and packaging the two models. The total times available for assembling, staining, and packaging are 3750 hours, 8950 hours, and 2650 hours, respectively. The profits per unit are $30 for model I and $40 for model II. What is the optimal inventory level for each model? What is the optimal profit?
A shoe wholesaler wants to optimize its shipment of shoes to its client retailers. To minimize their turnover time and avoid building up stocks that add costs, the wholesaler wants to know if weather conditions are important in determining the type of shoe demanded. Specifically, she / he would like to know if high temperatures affect the sale of closed, rubber-heeled walking shoes. He / she has the relevant data showing the temperature recorded at the location of its retail shops, as well as their record of sales of these walking shoes, during each day of the past year. What type of analysis should he / she conduct? What variables should be considered? Explain.
Suppose a manufacturer and its retailer face the problem of double marginalization described in my notes, Section 11.1. If the manufacturer sets the wholesale price equal to its marginal cost c and in addition, requires the retailer to pay a fraction α (between 0 and 1) of its profit. 4.a Write down the retailer’s profit maximization problem. Will this practice solve the double marginalization problem? (That is, will this practice maximize their joint profit?) 4.b Suppose the retailer is required to pay a fraction of α of its sales (i.e., total revenue). Write down the retailer’s profit maximization problem. Will this practice solve the double marginalization problem? I am posting chaper 11.1 notes below:
First Securities, Inc., an investment firm, has $380,000 on account. The chief investment officer would like to reinvest the $380,000 in a portfolio that would maximize return on investment while at the same time maintaining a relatively conservative mix of stocks and bonds. The following table shows the investment opportunities and rates of return. Investment Opportunity Rate of Return Municipal Bonds (X1) 0.095 High Tech Stock (X2) 0.146 Blue Chip Stock (X3) 0.075 Federal Bonds (X4) 0.070 a) The Board of Directors has mandated that at least 60 percent of the investment consist of a combination of municipal and federal bonds, at least 25 percent Blue Chip Stock, no more than 30 percent High Tech and Blue Chip Stock, and no more than 15 percent High Tech Stock. Based on above problem, how many constraints are in this problem? A) 3 B) 4 C) 5 D) 2 b) Based on part a, which of the…
A company that produces digital cameras in the USA has produced the following price-demand data in table 1: Table 1: Price-Demand X Millions P ($) 2 87 5 68 8 53 12 37 Using regression analysis, the company produced the following price-demand function to model the above data: Plot the data in table 1. Then sketch a graph of the price-demand function in the same coordinate system. What is the company’s revenue function for the cameras and what is it’s domain? Complete the following table. Then sketch a graph of the revenie function using these points. Revenue Table: X Millions P ($) 1 90 3 ? 6 ? 9 ? 12 ? 15 ?
2 A balanced design will be an orthogonal design True False 3 An orthogonal design will necessarily be balanced True False 4. A regression line with a categorical factor added in as well will essentially create separate trendiness for each of the levels of the categorical factor. True False 5 If there is an interaction between a categorical factor and a quantitative variable in a regression, it will allow the slopes to differ across the groups. True False 6 A quadratic model for a quantitative explanatory variable can be viewed as a self-interaction True False 7 If you have a categorical factor in a model where that factor does have an effect on the response variable, the F-ratio will tend to grow larger as the number of datapoints per level increases. True False 8 If you have a categorical factor in a model where that factor does have an effect on the response variable, the MSE tends to grow smaller as the number of…
An economist at Nedbank ran a study of the relationship between FTSE/JSE All Shares index return (JALSH) and consumer price index (CPI) from 2006 to 2017, the data collected is shown in the Table 1 below.

An economist believes there is a linear relationship between the marketprice of a particular commodity and the number of units suppliers of thecommodity are willing to bring to the marketplace. Two sampleobservations indicate that when the price equals $15 per unit, the weekly supply equals 30,000 units; and when the price equals $20 per unit, theweekly supply equals 48,000 units (i) If price per unit, p, is plotted on the horizontal axis and the quantitysupplied q is plotted on the vertical axis, determine the slope-intercept formof the equation of the line which passes through these two points.(ii) Interpret the slope of the equation in this application.(iii) Predict the weekly supply if the market price equals $25 per unit.
