Economics in One Lesson Economics in One Lesson Presentation Transcript

  • Economics in One Lesson Introduction to Economics Metropolitan University Prague Martin Kolmhofer 2011/2012
  • The Lesson
  • The Lesson
    • Focus on long run and all groups
    • Economics can be subject to vested interests
    • Long-run effects are more complex than short run
  • The Lesson
    • Hazlitt reported on Business for the New York Times and the Wall Street Journal for most of the first half of the last century.
    • In Economics in One Lesson he wanted to explain all the things he thought people got wrong in economics.
    • The insight itself is very easy: All it says is when you consider the effects of an economic policy you have to consider the effects on all groups and the effects in the long run, rather than just consider some groups in the short run.
  • The Lesson
    • Keynes: “In the long run we are all dead”
    • But: Most of us have children…
  • The Lesson
    • Example: Cash for Clunkers
  • Too good to be true?
    • Struggling car companies get new business
    • Some people get new cars
    • The environment gets cleaner
  • Long run effects on all people?
    • Low-income people who might want to buy a clunker. Government is now bidding against them.
    • People who don’t actually work for car companies?
    • Government spends tax money on Cash for Clunkers. Taxpayers can no longer spend that money on anything else. Jobs are lost elsewhere.
  • The Broken Window
  • The Broken Window
    • It is too easy to focus on immediate outcomes
    • Unseen hypothetical outcomes are just as important
    • We need to look at all possible outcomes
  • The Broken Window
    • Frederic Bastiat
    • That Which Is Seen and That Which Is Unseen”
    Frédéric Bastiat 1801-1850
  • The Broken Window
    • Glazier = Special Interest Groups
    • Boy = Government
    Charlie Chaplin “The Kid” (1921)
  • The Broken Window
    • Common examples of special interest groups practicing the broken window fallacy
    • Arguments for public works projects as a way to reduce unemployment. The hidden cost here is of course the tax payer's money, and the special interests are the jobs created by the public works.
    • Arguments for protectionist measures such as tariffs, subsidies and/or other regulations in order to protect local industries.
    • Inflation as a means to stimulate economic activity by making savings worth less
  • Public Work Means Taxes
  • Public Work Means Taxes
    • Paying for public works mean more taxes
    • Public works sometimes justify the taxes required
    • Public works costs and benefits can be distorted
  • Public Work Means Taxes
    • Government does not have anything – it can only take from some and give it to others
    • While public works seem to benefit people by providing employment, funding them requires the use of taxes.
  • Public Work Means Taxes
    • Suppose the government builds a bridge that is not  entirely justified by traffic needs. Two fallacies are at work here:
    • The construction of the bridge creates jobs.  
    • With the bridge in place, the nation is richer.
    • The taxes collected for the bridge are money that would have been spent   privately, on consumption or investment, and this expenditure   would have created jobs. For each job the bridge creates, one   is destroyed in the private sector. We do not see the lost   jobs because they are not in one place, as the bridge jobs  are. The same for the enhanced national wealth. The bridge is there, but the unbuilt homes, the unmade cars and clothes,   the ungrown and unsold foodstuffs, all that would have been   paid for by the money that instead went to taxes, are not.   Net gain: zero at best.
  • Public Work Means Taxes
  • Public Work Means Taxes
  • The Blessings of Destruction
  • The Blessings of Destruction
    • War cannot stimulate economies
    • War creates need, not ability to pay (demand)
    • Destruction can reduce productivity and ability to pay
  • The Blessings of Destruction
  • The Blessings of Destruction
  • Taxes discourage Production
  • Taxes Discourage Production
    • Tax raises revenue and changes taxpayers behavior
    • Tax collection discourages productive behavior
    • Tax policy should consider behavioral effects
  • Taxes Discourage Production
  • Taxes Discourage Production
  • Credit Diverts Production
  • Credit Diverts Production
    • Government lending always takes funds away from the private sector
    • Government lenders face lax incentives compared to private lenders
    • Worthwhile government loans don’t need government intervention
  • Credit Diverts Production
    • What is credit?
    • Something a bank “gives” to you or something you already have?
    • Credere (lat.) = to believe, to trust
  • Credit Diverts Production Government-guaranteed home mortgages?
  • The Curse of Machinery
  • The Curse of Machinery
    • Technology displaces some workers in the short term
    • It also employs people in developing the technology
    • Technology creates more wealth which creates more jobs
  • The Curse of Machinery 18 th century – industrial revolution - UK - textile industry - (Luddites)
  • The Curse of Machinery
  •  
  • Spread-The-Work Schemes
  • Spread-the-Work-Schemes
    • These practices spring from the  same fundamental fallacy as the fear of machines. This is the belief that a more efficient way of doing a thing destroys jobs, and a less efficient way of doing it creates them.
    • Job creation is important but should not be an end in itself
    • When more workers produce the same output, average production per worker is lowered - purchasing power is reduced
    • This reduces demand, creating less jobs
  • Spread-the-Work-Schemes Example: 35 hour week in France since 2000
  • Spread-the-Work-Schemes
    • The 35-hour working week is controversial in France. Generally speaking, left wing parties and trade unions support it, while conservative parties and employers' union oppose it. Critics of the 35-hour working week have argued that it has failed to serve its purpose because an increase in recruitment has not occurred; in their view, the reluctance of firms to take on new workers has instead simply increased per-hour production quotas. According to right-wing parties and economic commentators, the main reason why French firms avoid hiring new workers is that French employment regulations make it difficult to lay off workers during a poor economic period.
  • Disbanding Troops and Bureaucrats
  • Disbanding Troops and Bureaucrats
    • After war, many soldiers were in Europe and wanted to come home…people were afraid that they would inundate the US. There wouldn’t be jobs for them.
    • When millions of men are suddenly released - where is the "purchasing power" going to come from to employ them? 
    • Demobilization releases to the taxpayers the money to provide private jobs.
  • “ Purchasing Power" argument? When your money is taken by a thief, you get nothing in return. When your money is taken through taxes to support needless (?) bureaucrats, precisely the same situation exists. A man walks in a bar and asks the bartender to lend him 100 USD. He promises to spend them all in the bar… Conclusion: Always consider where the money that creates “purchasing power” comes from

  • The Fetish of Full Employment
  • The Fetish of Full Employment
    • Most political debates are about JOBS/EMPLOYMENT
    • Is work something desirable?
    • The economic goal of any nation, as of any individual, is to get the greatest results with the least effort
    • Real objective is to maximize production (we can very easily have  full employment without full production)
  •  
  • The Fetish of Full Employment
    • “ Job Creation” often really just means “redistribution” – if money comes from taxes, you might as well just give the workers the money...
    • Demand Side Solutions:
    • Government-funded employment
    • Hire people to dig holes and fill them up ?
    • Let people dig up buried money ?
    • Supply Side Solutions:
    • making the labor market more flexible
    • removing the minimum wage and reducing the power of unions
  • The Fetish of Full Employment
  • Who’s protected by Tariffs?
  • Who’s “Protected” by Tariffs?
    • Example: Suppose Congress is thinking of cutting or abolishing a tariff on sweaters. A sweater company shows that it would thereby be put out of business and its workers thrown out on the street. Congress relents. The company and its employees continue with their contributions to the American economy. What has been overlooked? Who has been harmed?
    • (1) The American consumer, who might have bought a  sweater at a lower price and had money left over to spend on  other things
    • (2) the companies that would have sold to that consumer
    • (3) their workers
    • (4) the foreign sweater-makers
    • (5) the American exporters from whom the foreign sweater- makers or their compatriots would have bought goods and services
    • (6) the governments that would lose revenues from  the general slowdown of business
    • VIDEO: WHY DO COUNTRIES RESTRICT TRADE?
  • Who’s “Protected” by Tariffs?
    • The Candlemakers' petition:
    • … is a well known satire of protectionism written and published in 1845 by Frederic Bastiat.
    • All the people involved in the French lighting industry, including "the manufacturers of candles, tapers, lanterns, sticks, street lamps, snuffers and extinguishers, and from producers of tallow, oil, resin, alcohol, and generally of everything connected with lighting“ call upon the French government to take protective action against the “unfair competition” of the sun. 
  • The Drive for Exports
  • The Drive for Exports
    • In the long run imports and exports must equal each other.
    • It is exports that pay for imports, and vice versa. The greater exports we have, the greater imports we must have, if we ever expect to get paid. Without imports we can have no exports, for foreigners will have no funds with which to buy our goods.
  • The Drive for Exports
  • Hume: Price-Specie Flow Mechanism
    • Importing money in exchange for exports – causes inflation – makes exports less competitive
    • Exporting money in exchange for imports – causes deflation – makes exports more competitive
    Therefore Hume argued that a trade balance is relatively unimportant because it tends to balance itself out in the long term.
  • China - US
    • China exports
    • U.S. imports
    • Sustainable?
    • China keeps currency artificially low:
    • By keeping its currency undervalued, China is discounting its own exports.
    • China's central bank needs to constantly buy U.S. Treasury bonds.
  • Parity Prices
  • Parity Prices
    • What are "parity prices?”
    • “ Purchasing Power Parity (= Equality)” over time – a plea to keep prices up
    • Falling prices are a good thing ( increased productivity)
  • Parity Prices
    • Example: Subsidized prices for farm products
    • Consequence: Higher prices for food
    • Consumers spend less on other products
  • Parity Prices
    • We are all producers (sellers) and consumers (buyers) in a sense
    • Discussion: Rising Stock Prices positive? Rising Food / Oil prices negative?
  • Saving the X Industry
  • Saving the X industry (Why Bailouts don’t work)
    • Typical industries: Banking, Auto, Agriculture, Defense
    • The idea that an expanding economy implies that all industries must be simultaneously expanding is a profound error. In order that new industries may grow fast enough it is necessary that some old industries should be allowed to shrink or die.
  • Saving the X industry
    • What are the ways that politicians attempt to save Industry X ?
    • Direct subsidy = Transfer of wealth, taxpayers lose, less spending, other industries shrink
    • Prevent competition = create monopoly (same chain of reasoning)
  •  
  • How the Price System Works
  • How the Price System Works Example: Automatic "governor" on a steam engine: Every departure from the desired speed itself sets in motion the forces that tend to correct that departure.
  • How the Price System Works
    • It is precisely in this way that the relative supply of thousands of different commodities is regulated under the system of competitive private enterprise.
    • Question: Why don’t we produce so much chocolate to cover all unmet “needs”/”wants”?
    • Answer: Resources have alternative uses / Competing Bids create structure of production
  • All Scarce Goods Must Be Rationed Somehow… Alternative Rationing Mechanisms to the Price System:
    • Queuing ( Waiting in line as a means of distributing goods and services, „first come, first served“ )
    • Ration Coupons ( Tickets or coupons that entitle individuals to purchase a certain amount of a given product per month )
    • Favored Customers ( Those who receive special treatment from dealers during situations of excess demand. )
    • Rationing according to „needs“
    • Lottery
    • Equal shares for all
    • „ Might makes right“
    • Problem: Excess demand is created but not eliminated
  • All Scarce Goods Must Be Rationed Somehow
  • Stabilizing Commodities
  • Stabilizing Commodities
    • Price Floors
  • Stabilizing Commodities Price Floors
    • Side-effects:
    • Consumers find they must now pay a higher price for the same product. As a result, they reduce their purchases or drop out of the market entirely.
    • Suppliers find they are guaranteed a new, higher price than they were charging before. As a result, they increase production.
  • Stabilizing Commodities Price Floors
    • Example: CAP (Common Agricultural Policy) in EU
    • “ Butter Mountains”
    • “ Milk Seas”
    • Because of this problem, the EU stopped these price floors and just pays former farmers regardless of what they do, so as not to cause any undesired indirect effects on the economy.
  • Government Price Fixing
  • Government Price Fixing Price Ceilings
  • Government Price Fixing Price Ceilings
    • Side effects:
    • Supply decreases
    • Quantity demanded increases
    • SHORTAGE (unless rationing or other consumption controls are enforced)
    • Other forms of non-price competition (Black Markets, Queuing…)
  • Government Price Fixing Price Ceilings
    • Would you rather KNOW that you can buy petrol at 2 USD per gallon or HOPE that you can get petrol at 1 USD per gallon?
  • Minimum Wage Laws
  • Minimum Wage Laws
    • Side effects:
    • They reduce employment opportunities for less-skilled workers
    • When a law exists that no one is to be paid less than $64 for a 40 hour week, then no one whose services are not worth $64 to an employer will be employed at all.
    • Example: Teenage unemployment
  • Minimum Wage Laws
    • Special Interests: Trade Unions
  • Enough to Buy Back the Product
  • Enough to Buy Back the Product
    • Fallacy: “People cannot buy back what is produced” because they are not paid enough
    • Lack of demand? “Underconsumption” theories
    • Saving as lack of demand?
    • Laborer’s wage is his purchasing power, but also the business’s profits are the owner’s purchasing power
  • Enough to Buy Back the Product
  • The Function of Profits
  • The Function of Profits
    • Is profit something negative/immoral?
    • Profits serve to guide and channel the factors of production
    • Profits result from forecasting the future – and future consumer needs
  • The Function of Profits
    • Entrepreneur is continuously scanning the market for undervalued resources with the intention of combining them and then bringing them to market in a much higher valued product.
  • The Function of Profits
    • Losses signal a waste of resources: It means that resources have a higher value to consumers in other areas than the product that is being produced
  • The Function of Profits
    • Profit System = system in which people are using resources efficiently and serving others
    • Profit guides everybody to get more value out of the limited resources that exist
  • The Mirage of Inflation
  • The Mirage of Inflation Setting the alarm clock earlier?
  • The Mirage of Inflation
    • What is the difference between wealth and money?
    • What are the various justifications people give for inflationary policy?
    • What is the basic process by which the money supply is inflated?
    • What does inflation do to the "structure of production?"
    • In what sense can inflation counteract problems of above-market wage rates?
    • Why is inflation so popular among many government officials?
    • What is the worst-case outcome of inflation?
  • The Mirage of Inflation
  • The Assault on Savings
    • People save for good reasons
    • Money saved does not reduce employment
    • Saving helps expand the economy
    The Assault on Savings
  • The Assault on Savings
    • What is the difference between consumer goods and capital goods, and how is savings related?
    • What is the difference between saving and withholding spending? What causes each?
    • What harmonizes savings and investment on a free market?
    • What is the result of keeping interest rates artificially low?
  • The Assault on Savings
    • The two brothers:
  • The Assault on Savings
    • "Saving" is only another form of spending.  
    • Interest rate is the relevant price that translates savings into investment
  • The Assault on Savings Virtually low interest rate leads to misallocation of resources. Projects cannot be completed because real savings are missing. (Construction Bubbles…)
