Ten years ago, the town of Easton decided to increase its annual spending on education so that its high school graduates would be able to earn higher wages. Now Easton has asked you to evaluate the effectiveness of the spending increase. Their data show that before the spending increase, the average annual salary of recent high school graduates was $25,000 and that now that average salary has risen to $28,500. Fortunately for your analysis, a neighboring community (Allentown) did not change its annual spending on education. Ten years ago, recent Allentown high school graduates earned an average of $22,500, and now that average is $23,750.
(a) Use a difference-in-differences estimator to determine whether Easton’s spending increase caused the wages of their high school graduates to increase.
(b) What underlying assumption do you have to make in order for your estimate to be valid? What might cause your underlying assumption to be invalid?
(c) This data set contains only two…

Online shopping attracted a great deal of attention from researchers over the past two decades. The advent of the Internet and other disruptive technologies has had a fundamental effect on how consumers buy goods and services today. People can now order groceries online to be delivered to their homes, but this is still a relatively new concept in the South African market. Consumers remain sceptical about this way of shopping. Many researchers have studied consumer behaviour of online shopping and the conceptual factors influencing their intention to purchase groceries online. However, the influence of personality traits on consumer willingness to adopt online grocery shopping is largely under researched, especially in South Africa.

- Juanita is deciding whether to buy a suit that she wants, as well as where to buy it. Three stores carry the same suit, but it is more convenient for Juanita to get to some stores than others. For example, she can go to her local store, located 15 minutes away from where she works, and pay a marked-up price of $104 for the suit: Store Travel Time Each Way Price of a Suit (Minutes) (Dollars per suit) Local Department Store 15 104 Across Town 30 87 Neighboring City 60 80 Juanita makes $36 an hour at work. She has to take time off work to purchase her suit, so each hour away from work costs her $36 in lost income. Assume that returning to work takes Juanita the same amount of time as getting to a store and that it takes her 30 minutes to shop. As you answer the following questions, ignore the cost of gasoline and depreciation of her car when traveling. Complete the following table by computing the opportunity cost of Juanita's time and the total…arrow_forwardYou have decided to start a snow-plowing business whereby you will offer to plow the driveways of your neighbours' homes after heavy snowfalls. You are well known by everybody in your neighbourhood, you have a plow for the front of your truck, and you think that your neighbours would rather hire you than someone they do not know. From your research, you know that homeowners are charged an average of $40 to plow their driveways after a heavy snowfall. Interestingly, a few years ago, your research tells you that homeowners were charged an average of $25 to plow their driveways after a heavy snowfall. The average price has gone up, which excites you. Apply your learning about supply and demand to this fact pattern to analyze possible reasons for the increase in price. Consider the five factors that may impact demand and the 6 factors that may impact supply. What questions do you want answered before committing to this business?arrow_forwardIf your overall grade point average is 2.0 and you earn a 2.5 GPA this semester, your overall grade point average will increase. This situation demonstrates the general principle that if average value is greater than marginal value, marginal value will increase. if average value is greater than total value, total value will increase. if marginal value is greater than average value, average value will increase. if marginal value is greater than total value, total value will increase.arrow_forward
- U.S. food markets consumers viewed beef as a normal good from 1960-1976, but viewed it as an inferior good after that point. This type of change is not abnormal, in that as average household incomes rise, preferences might change. For instance, as households move from poor to middle-class, their consumption of beef might increase. However, as households move from middle- class to upper-middle-class, they might choose to purchase more exotic foods products. Assuming you are a beef producer in 1983, what will happen if incomes continue to increase? a. The marginal cost of beef will increase. b. The marginal cost of beef will decrease. c. The demand for beef will increase. d. The demand for beef will decrease.arrow_forwardYou own a printing firm. Two of your senior managers provided you with advice. The first manager states that your company is losing money for every unit that is printed. To minimize losses, she advises that you reduce your production levels.

In order to reduce losses, the second manager recommends that you should increase production.

Each had a few cans of bacon (D) and a few packs of macaroni cheese (M). Budi has quite flexible tastes and has a UB satisfaction function = 4D + 3M. Ahmad is a very picky person and will only eat smoked meat and cheese macaroni with a combination of 1 can of smoked meat and 2 packs of macaroni cheese. Ahmad's level of satisfaction is UA=min(D,M/2). There are only 100 cans of bacon and 200 packs of macaroni cheese. Questions: a. Draw an Edgeworth Box diagram illustrating the possible trade-offs that occur under these conditions. Determine the possible exchange rate in equilibrium. b. Suppose Ahmad has 40 cans of bacon and 80 packs of macaroni cheese. Determine the equilibrium that will occur. c. Suppose Ahmad has 60 cans of bacon and 80 packs of macaroni cheese. Determine the equilibrium that will occur. d. Suppose Ahmad, who is stronger than Budi, decides not to follow the agreed exchange rules. Determine the equilibrium that will occur.arrow_forwardWhen a company offers a new product or service, they estimate how much of that product or service people will want at different prices. This is referred to as the product or service demand. As the price of a product or service increases, the demand usually decreases, and this drives the price down. Companies use the estimated demand to determine how much of a product or service they are willing to supply at different prices. As the price of a product or service increases, companies are willing to supply more of it because they will earn more money. If you graph the demand and the supply curves on the same xy-plane, they will sometimes intersect at the point where the price and the supply are in equilibrium. Consider the scenario below. Yaseen is a local artist who wants to increase the amount of money she earns every month by selling at-home painting kits. These kits will include a photograph of the finished painting, a link and password to Yaseen’s YouTube channel where she will…arrow_forward
- The following data pertain to products A and B, both of which are purchased by Madame X. Initially, the prices of the products and quantities consumed are: PA = $10, QA = 3, PB = $10, QB = 7. Madame X has $100 to spend per time period. After a reduction in price of B, the prices and quantities consumed are: PA = $10, QA = 2.5, PB = $5, QB = 15. Assume that Madame X maximizes utility under both price conditions above. Also, note that if after the price reduction enough income were taken away from Madame X to put her back on the original indifference curve, she would consume this combination of A and B: QA = 1.5, QB = 9 Determine the change in consumption rate of good B due to (1) the substitution effect and (2) the income effect. Determine if product B is a normal, inferior, or Giffen good. Explain.arrow_forwardSeven years ago, you started a cross-town delivery service. You have two types of deliveryservices. You have a small parcel service for anything that is flat and measures less than 11x17. You have a package service using a 100 lb capacity bike trailer for anything weighting up to 10lbs. Initially, you charged the same price for each service, but since the beginning of the Covid19 pandemic you have seen an increased in the demand for your package service. The demand for the package services seems to be more inelastic than the demand for parcels. You are now wondering if you should charge different prices for the parcel and package service or should you segment the market and charge two different prices?
