A study in 2008 looked at how commuters' commute time changed when car pool lanes were added in Georgia. In 1999 -- before the lanes were added the average commute time in Florida -- (with no new car pool lanes) was 20 minutes and in Georgia was 25 minutes. In 2006 -- after the lanes were added -- those numbers were both equal to 30. What is the diff-in-diffs estimate of th effect of adding these lanes in Georgia? Input the number as a whole number with no decimals, ar be sure to include it as negative if the effect was to decrease commute times in Georgia. If you cannot say without more information, input 99.

It is known that the ABC oil company supplies consumers with 150 tons of products per day. The company produces only two types of products - gasoline and diesel fuel. The limiting transformation ratio of diesel fuel relative to gasoline is 0.5. a) Draw a line of the company's monthly production capacity for gasoline and diesel. b) With the advent of new technologies, production increased by 20%, and the availability of gasoline increased by 30%. Explain how the company's new product line differs from the previous one. c) If we put the gasoline production on the X-axis of the graph, what percentage of the slope capacity of the production line is different from the slope ratio of the previous production line?

A country’s gini co-efficient was 0.46 last year and is now 0.48. What can we infer from the change? What would it mean if a country had a co-efficient of 0 or 1?
Suppose that the government wants to estimate the effect of PKH on children's height usine WHO's height-for-age metric. Using administrative and surveydata, a researcher evaluates the impact of PKH using the following specification: (image insert) 1. What is the expected sign of beta? What assumption needed to obtain an unbiased estimate of beta 1? 2. is the assumption sensible? what are the consequence of violating the assumption! Discuss whether the estimated coefficient beta 1, positively or negatively bias? 5. do you think adding variables would fulfill the assumption?
A study by University of Minnesota economist, Joel Waldfogel, estimated the difference in the actual monetary value of gifts received and how much the recipients would have been willing to pay to buy them on their own. The study suggested that the average recipient’s valuation was approximately 90% of the actual purchase price. a. In 2017, it was estimated that the average amount spent on winter holiday gifts in the United States was $906. Based on the estimate from the Waldfogel study, how much of this would be deadweight loss? Enter your answer to the cent. b. In 2017, approximately 250 million people in the United States were above the age of 18. Assuming that each individual purchased $906 worth of gifts, what was the total deadweight loss associated with gift-giving in the United States? Round your answer to the nearest billion dollars.
s EconomicsQ&A LibraryEach term (3 months) the current group of economics students completed a questionnaire as to how much they would spend on new purchases compared to how much they would save/pay off bills, if they suddenly and unexpectedly received a check for $1,000.

Consider a class with 80 enrolled students. None of the students were ill at the beginning of the school year. On August 30th, 10 students reported having a common cold. All continued to be ill on September 1st, but all 10 recovered within 3 days. On September 15th, 5 more students had a cold. All of these students continued to be ill on September 16th, but all recovered 5 days later. In this example, assume that a person cannot have a cold more than once.calculate the cumulative incidence of the common cold in the class during the month of september
Suppose that the government tends to maximize the tax revenue. How would the cannabis price drop affect the government tax revenue if cannabis was taxed by price? Did the government anticipate the cannabis price drop when designing the tax scheme? You may come up with an artificial numerical example to support your findings. are alcohol and cigarettes substitutes or complements of cannabis?(The answer to this question depends on the actual consumption data. If you do not know the data, you may make an assumption. Then, you should stick with this assumption for the rest of your analysis. For example, if you assume that alcohol and cigarettes are substitutes of cannabis, then your entire analysis is based upon this assumption.) How would the change in the price of cannabis possibly affect the market demand curve for alcohol/cigarettes?

GNP: PLUSES AND MINUSES The gross national product in recent years has basked in the warm glow of nearly universal praise. Econo mists, quite naturally, have been freest with the encomiums. Where else but the GNP could they get in one tidy number a measure of the growth in the mammoth U.S. economy. Businessmen, though not entirely persuaded of the value of statistics, especially esoteric statistics, nevertheless have been known to quote the GNP—possibly because of its powers to impress audiences with the speaker's grasp of the "big picture." Politicians, too, have been extravagant in their admiration of GNP, most especially when it was rising at a brisk pace. Even the ubiquitous cocktail party has paid homage to the GNP as assorted junior executives, research assistants, housewives, and dancing instructors have pronounced on the latest GNP numbers with a solemn and knowing air. Now all that seems to be changing. GNP increasingly is coming under attack. Dr. Arthur F.…
