Candy Bar Case Study

Great Essays
1) Assume that the demand curve for an imported candy bar can be expressed as € PD = 4.60 − 0.0001Q, and the supply curve can be expressed as € PS = 0.2 + 0.0003Q. a) What is the price and quantity at which the market clears?
The price and quantity at which the market clears is $3.50 and 11,000 respectively. b) What is the value of the consumer surplus and the producer surplus in this market?
The consumer and producer surplus are $6,050 and $18,150 respectively. The overall benefit to society from producing and consuming candy bars is $24,200.
c) Imagine that a new factory opened up which could make the item much more cheaply. Would this affect the supply curve, demand curve, neither, or both? Write a new equation or set of equations that

In a 2009 article written by Martin Weitzman in the journal The Review of Economics and Statistics, Weitzman interprets the economics of catastrophic climate change. In his study was based off of the implications of structural uncertainty for low probability economics and high impact catastrophes. His theoretical model finds that large disasters with moderate probabilities are likely to create high cost. In the Technological Forecasting and Social Change journal Richard Rosen attempts to address what “we” know about the economics of climate change. He finds that long-term economics of mitigating climate change cannot accurately determine the net cost and benefits, in which estimates are likely to create low cost.
The cause for the different interpretations of these studies is likely due to the variables they found significant for their models. Weitzman found that IAM results were accurate and based his model off of their assumptions, while Rosen found IAM results to be skewed. Rosen attempted to minimize the uncertainties when predicting net

Geoengineering is the artificial manipulation of earth’s climate to offset environmental changes that are anthropogenically caused. The major positives of geoengineering would be cleaning up and restoring the atmosphere to safer levels of greenhouse gas that would ultimately minimize the negative effects of global warming. However, geoengineering could increase the effects of global warming by interrupting/amplifying the feedback effects of the carbon cycle. As well as allowing people to continue habits that produce high levels of greenhouse gases, with little consequences.
4) Think about the Sendel and Stavins papers. What do you think the strongest point Sendel makes is? Given that tradeable permits essentially allow companies to pay to pollute, how do you think Stavins would respond to Sendel? Explain your thoughts on balancing (or choosing between) “efficiency” and “fairness” in pollution trading

    I got stuck on the linear equations when I was trying to isolate p. One of my problem solving strategies was looking for relationships with the data I had to uncover the missing information. Solution: 375 stands for the whole cost meaning 3 bags of potato chips and 4 candy bars in Ralph’s equation. A similar equation, using p and b, for the items Jody bought is 4p+2b=300. One bag of potato chips costs 45 cents and one candy bar costs 60 cents.…

    With above average conditions for supply, the supply curve will shift to the right to SA. With below average condition for demand (economic recession, low substitute price, etc.) the demand curve will shift to the left to DB. The equilibrium price and quantity for this market will be set at price PL and quantity Q0. If there are below average conditions for supply, SB, and above average conditions for demand, DA, then the supply curve will shift to the left and the demand curve will shift to the right.…

    The article titled Florida Lawsuits Allege Price Gouging, discussed how establishments, specifically, Days Inn and Crossroads Motor Lodge, used price gouging after Hurricane Charley. Both establishments advertised rooms under $50.00 a night; however, once guest arrived to rent rooms they were turned away or told the price was higher than originally promoted (CNN, 2004). During this year, the Florida State Statutes stated, during a state of emergency it is considered to be “unlawful and a violation of s. 501.204” for establishments to change the price of specific products (Online Sunshine, 2017). The graphs that best fit this situation are A and D. To elaborate, graph A was chosen because the number of rooms Days Inn and Crossroads Motor Lodge offered decreased making the demand for them upsurge. I also chose graph D because the number of rooms available decreased which created a higher demand.…

    The concept of geoengineering proposes that earth’s natural systems are no longer effective by human standards, and thus, should be altered to accommodate for our needs. From an environmental point of view, this is out of the question. An environmentalist’s mindset is one of unity with nature and cooperation with the natural ecology of the world. Geoengineering, although it may combat issues caused by industry, completely disregards the collaboration and harmony with nature that we once held millennia ago. In this way, geoengineering avoids the cause of our species’ environmental dilemma altogether, and thus, is not a truly viable…

    In several respects, global climate change (GCC) represents new conditions. It is not just extreme events and changing rainfall patterns that have started to affect individuals in various parts of the world. There are also discussions in the political community regarding activities of mitigation and adaptation because of climate change. Decisions by others predict effects (by politicians regarding road toll systems, extra taxes on fossil fuel, etc.) even for those who are not personally concerned.…

    He states that he believes the issue of climate change is less of the utter catastrophe that most news outlets seem to make it out to be, and that it will moreso be a problem humanity will adapt to with little struggle. He begins by noting how the IPCC apparently believes that global warming will only serve a minor inconvenience, and how people will simply need to mitigate and adapt in order to survive. The paper then moves to describe various apocalyptic predictions dating back to the beginnings of civilization to the present. These are compared to the…

    Specifically, the author related these concepts to Tide PODS®. However, realistically, a discussion of these concepts must occur in relation to each other to understand how the product will perform in the market. When the supply curve and demand curve are combined on the same chart, the point in which the supply curve and demand curve intersect at a particular price is the market equilibrium price. This is the point in which the amount of product a firm produces meets the demand.…

    It is largely the opinion of climate change experts that geoengineering solutions are not to be relied upon to fix the problems of climate change alone. However, geoengineers are planning ahead for a future where the world may be forced to take emergency measures to protect against the devastating effects of a much warmer planet. Some ideas are more radical, where others may be useful even today to support the global transition away from excess CO2 emission. Solar radiation management may be a last resort to give people slightly more time to fully integrate pollution free systems into society. However, atmospheric carbon dioxide removal can be more realistically implemented immediately.…

    Inspired by a forsaken orange that sat in a North Carolina parking lot, Jonathan Bloom wrote American Wasteland to examine the growing problem of food-waste in America. I think Bloom did a tremendous job by presenting this looming issue. His numerous anecdotes pertaining to food-waste creates an innate sense of relatability, which in turn direct readers’ attention to the statistical and logical presentations of the issue. This is an impressive feat because Bloom avoided coming off as preachy or judgmental in a book that attempts to raise awareness of something that general Americans have already decided it’s not important (xvi). As a result, Bloom’s systematic way of examining every aspect of America's habit of wasting food comes off as interesting…
