    Energy Policy Decisions

    Mar 21 • Demand, Supply, and Markets, Developing Economies, Economic Debates, Economic History, Environment, Regulation, Thinking Economically • 539 Views

    Comparing the safety of nuclear power, oil, and coal, Slate columnist William Saletan helps us make some energy policy decisions.

    His focus is fatalities. In the oil supply chain, from 1969-2000, he cites 20,000 deaths. For coal, the number is 15,000 (although he does not state the time period). By contrast, except for Chernobyl, deaths from nuclear power accidents total zero. In the article, he does not talk about natural gas.

    His conclusion? Nuclear power is relatively safe. Yes, Congress should look at how to make it safer but then, we should not prohibit construction.

    The Economic Lesson

    Totaling close to 80% of all energy sources in 2009, oil, coal, and natural gas provide most of the energy supply that we consume in the U.S. On this graph, nuclear power has an 8.3% slice.

    What are the “demand sectors?” Transportation, industrial, residential and commercial, electric power.

    We Are Living Longer

    Mar 20 • Gender Issues, Government, Households • 482 Views

    Using data for 2009 from death certificates in all 50 states, the national Centers for Disease Control has concluded that we are living longer. A male infant’s projected life span has risen .2 years to 75.7 while a female infant’s life expectancy is up .1 years to 80.6. An interesting chart in the report notes projected longevity for ages 0-100. Females at age 100 are estimated as having 2.2 years left. 65-year old males have a projected life span of 82.3.

    Living longer, though, means that Social Security will need more money unless changes are made. Proposals from the deficit commission appointed by President Obama include the following (pp. 48-53):

    • Gradually increase the age that we start to receive Social Security benefits.
    • Gradually increase Social Security taxes.
    • Decrease what higher earners receive.
    • Encourage more personal retirement saving.

    The Economic Lesson

    The future of Social Security takes us to two basic concerns.

    1. Life expectancy: When Social Security was created in 1935, the average lifespan was 64 and benefits could begin at age 65. Now, life expectancy can extend beyond 80.
    2. Ratio of workers to beneficiaries: Called pay-as-you-go, the Social Security system has current workers funding retirees’ benefits. Because of the baby boomers, the worker/retiree ratio is plunging. In 1950 there were 16 workers for every beneficiary and now it is 3:1. The projection for 2025 is a ratio of 2.3 workers for every retiree.

    Disaster Economics

    Mar 19 • Businesses, Developing Economies, Economic History, Economic Thinkers, Environment, Government, Macroeconomic Measurement • 512 Views

    Assume an economy has been steadily growing. Then a natural disaster strikes, maybe a hurricane, an earthquake, or a tsunami. How is growth affected? While conclusions differ slightly, the consensus indicates that after 5 years and sometimes much sooner, previous growth levels return.

    Reuters and The Economist have good descriptions of why. In a disaster area, when physical capital is destroyed, potentially productive human capital remains.  Outside the area, underutilized plants and labor can compensate for lost capacity elsewhere. In addition, replicating productive facilities might be easier than designing new ones. And sometimes, destruction begets creativity that improves what had existed.

    We should ask, though, whether advanced economies are more likely to grow after a disaster because they have the resources to prepare for a crisis beforehand and recover after one. According to one study, advanced economies do fare much better after disasters than less developed economies. By contrast, a 2010 Inter-American Development Bank Study concluded that natural disasters do not ultimately change a nation’s growth trajectory unless radical political change occurred after the calamity.

    This NY Times Economix blog provides a good summary of existing articles.

    The Economic Lesson

    Born in Kharkov, Russia, a gentleman whose name was Simon Kuznets arrived in the United States in 1922. 26 years old, he soon went to work at the National Bureau of Economic Research.

    Dr. Kuznets became the Nobel Prize winning economist who developed the concept of national income accounting. National income accounting creates a national balance sheet that lets us know what is produced and the different incomes producers earn. Because of the work of Dr. Kuznets and his associates, we are able to calculate economic growth through the gross domestic product.

    Soda Wars

    Mar 18 • Businesses, Demand, Supply, and Markets, Households • 824 Views

    Diet Coke just pushed Pepsi out of the #2 spot in soda sales.

    Other soda facts…

    As reported by Beverage-Digest, Coke (17%) remains the most popular carbonated soft drink with Diet Coke (9.9%) next and then Pepsi (9.5%) and Mt. Dew (6.8%). The number next to each brand is its market share. Fanta, a Coca-Cola brand, is last among the top ten names.

    As for each firm’s market share, Coca-Cola is at 42%, PepsiCo, 29.3%, Dr. Pepper Snapple 16.7% and Cott Corp., 4.8%. Among the “premium priced energy drinks,” Red Bull is first with a .8% share of the market.

    Total sales of carbonated drinks indicate that we are drinking less soda. Our consumption of the top three brands, Coke, Diet Coke and Pepsi declined. However, sales of Diet Mountain Dew and Diet Dr. Pepper were up. Similarly, we are buying more Dr. Pepper, Mt. Dew and Sprite.

    Should Pepsi have had a super bowl ad?

    The Economic Lesson

    Competing in an oligopolistic market, it is crucial for Coca-Cola, PepsiCo and Dr. Pepper Snapple to achieve product differentiation through non-price competition. An oligopoly is a market that typically has several large, mass producing dominant firms and many customers. Market entry and exit are difficult.

    Presidential Pay and the GDP

    Mar 17 • Government, Households, Macroeconomic Measurement, Thinking Economically • 430 Views

     The Economist decided it would be interesting to know how a political leader’s pay compares to what a typical citizen from that country earns. Here are some of the numbers with salary first and then the multiple of per capita GDP next. I’ve approximated because the numbers are from a bar graph:

    Kenya: $486,000 (proposed), 240x

    Singapore: $2,183,516, 42x

    Indonesia: $124,171, 28x

    U.S. $400,000, 8x

    Israel $120,814, 4x

    China: $10,633, 2x

    You might want to look at this per capita GDP list to see worldwide poverty and affluence firsthand. Qatar is #1 ($145,300) while Burundi and Democratic Republic of Congo are last at #’s 228 and 229 ($300). The dollars are 2010 estimates.

    As a second step, you might check income distribution. In a list of 136 countries, Sweden is ranked as having the most income equality. Sweden ($39,000) is #23 on the per capita GDP list.

    The Economic Lesson

    GDP indicates the total value of goods and services produced in one nation during one year. Per capita GDP is GDP divided by population. Because these GDP figures are averages, it is helpful also to look at data that relates to inequality.
