Your friend gives you the data from a day of taco sales at each of the 40 food trucks, and asks you to estimate a demand curve. They let each taco truck driver set their own price, so there's lots of variance in prices. Qi =B0 +B1 Pi +ui j=1to40. You look at the data and discover that the correlation of Q and P is positive in this sample. Your friend laughs at you, --they learned in high school that demand curves slope downwards Explain how a positive correlation of Q and P might happen, by describing at least one real life omitted variable that might result in a positive correlation, and using the terms linear causal effect and the omitted variable bias formula

Case 1: A local bakery has noticed a decrease in the demand for their pastries. They found out that a new bakery in town is offering similar pastries at a lower price. What should the local bakery do based on demand analysis? Case 2: A clothing store wants to estimate the demand for a new line of summer dresses. They have historical sales data for similar dresses. What method should they use for demand estimation? Case 3: A tech company is launching a new product. They want to forecast the demand for the product for the next year. They don't have historical sales data for similar products. What method should they use for demand forecasting? Case 4: A manufacturing company is trying to determine the cost of producing a new product. They know that the cost of raw materials and labor will increase with the number of units produced, but the cost of the machinery will remain the same regardless of the number of units produced. How should they categorize these costs in their cost analysis?…
You are helping a friend that owns a local store. Their costs are per unit, so the only way they can maximize profits are by increasing revenue. Therefore, you would like to help identify the price that will maximize revenues. Below is data from a previous period. Complete the chart. (For the TR Test, consider that prices are increasing

3. Your marketing research department provides the following estimated demand function for your product: QD = 150 – 6.5P + 0.3Income, where P is the price of your product and Income is the average income of the consumers for your product. a. The T statistic for the price coefficient is -2.2. What can you conclude about the coefficients statistical significance? Explain.
How is tomato related to cabbage? Compute and interpret the cross elasticity of supply of cabbage with respect to the dealer’s price of complete fertilizer. If the price of complete fertilizer increases by 20 percent, by how much will the supply of cabbage change, holding other factors constant?
In a certain market, the demand for peach was given as QD = 400 -3P, the first day of marketing in 2020, in August 2020, the demand for peach is now given as QD = 200 -3P. a)From the statement above tell in one sentence the change in demand; considered the indicator? b)What factors are responsible for the change in demand. Support your answers by sketching the equations above on the same graph.
According to studies undertaken by the U.S. department of agriculture, the price elasticity of demand for cigarettes is about +0.5. Suppose a major brokerage firm advised its clients to buy cigarette stock under the assumption that, if consumer income rise by 50 percent as expected over the next decade, cigarette sales would double. Based on the fundamental economic principles on income elasticity of demand, a reasonable reaction to this investment advice would be?
Jim's Camera shop sells two high-end cameras, the Sky Eagle and Horizon. The demand for these two cameras are as follows (DS = demand for the Sky Eagle, Ps is the selling price of the Sky Eagle, DH is the demand for the Horizon and PH is the selling price of the Horizon): Ds = 230 - 0.5 Ps + 0.38 PH DH = 260 + 0.1 Ps - 0.62 PH The store wishes to determine the selling price that maximizes revenue for these two products. Select the revenue function for these two models. Choose the correct answer below. (i) Ps Ds + PHDH = PH(260 - 0.1 Ps - 0.62 PH) + Ps(230 - 0.5 Ps + 0.38 PH) (ii) Ps Ds - PH DH = Ps(230 - 0.5 Ps + 0.38 PH) - PH(260 - 0.1 Ps - 0.62 PH) (iii) Ps Ds + PH DH = Ps(230 - 0.5 Ps + 0.38 PH) + PH(260 + 0.1 Ps - 0.62 PH) (iv) Ps Ds - PH DH = Ps(230 + 0.5 Ps + 0.38 PH) - PH(260 - 0.1 Ps - 0.62 PH) Answer: Option 3 Find the prices that maximize revenue.

Page 2 3. In a study ("Price elasticity in the performing arts" by Kolhede, Gomez-Arias & Maximova 2023) researchers surveyed residents in one California county. They used responses to 28 questions about motivations to attend events to develop motivation factors and then clustered respondents into 3 segments based on their motivations. The authors estimated the performing arts event demand for each segment and calculated the demand elasticities at different prices and reported the following: Elasticities for the 3 segments with a $20 Admission Price were 0.317, 0.343, and 0.317 Elasticities for the 3 segments with a $60 Admission Price were 2.608, 3.269, and 2.590 Unitary Elasticity was at $41.50, $39.18, and $41.58 for the 3 segments Assume that the cost of event production is fixed (not related to attendance). As an economics expert, you are asked to help the performing arts group set ticket prices for next season. a. One committee of the performing arts group wanted to maximize…
