You are studying economics at a time of enormous changeThis is a meaningless statement always true, but economic principles do not change (only our understanding)

4You are studying economics at a time of enormous changeThe next few slides are to illustrate some of that change. What policies can and will lead to better times ahead?

http://www.calculatedriskblog.com/See graph galleries at http://www.crgraphs.com/ These lines represent all of the recessions in the post WWII era. They start at zero job losses and end when that point is again attained.Each are centered on the trough or low point of the recession.The horizontal axis depicts the number of months it took to get to the deepest part of that recession and the number of months after to recover.

A steep increase from the dotted line (trough) means the recession ended quickly and typically with much growth.

Click once to see the graph Then click again to see the last or Great Recession included.

We typically fully recover within 1 year or less.Most estimates show this not recovering until 2016 or later.http://www.calculatedriskblog.com/See graph galleries at http://www.crgraphs.com/

https://research.stlouisfed.org/fred2/tags/series All economic questions arise because we want more than we can get (wants always are greater then needs)scarcityMake tradeoffsMake choicesEverything is scarce and that is why we economizeThings that are scarce end to be more valuable.11a reward that encourages an action or a penalty that discourages an action.

All economic questions arise because we want more than we can get.Incentives matter! a reward that encourages an action or a penalty that discourages an action.Your first question in all economic analyses must be what are the incentives for the various parties involved?12a reward that encourages an action or a penalty that discourages an action.

Develop an Economic Way of ThinkingTo paraphrase a former President of the US It is not that people do not know economics, it is that they know so much of economics that isnt so13Can destruction be good? Can it lead to jobs and capital investment?

If you think so, you have madeA broken window fallacy of economic reasoning.

Dont feel bad you are sadly in good company.

watchThe Broken Window Fallacy

The broken window fallacy is described in Chapter 2 of Economics in One Lesson.

Thats right, one easy lesson, which is Chapter 1.

In fact, Hazlett purports to only need one sentence

the whole of economics can be reduced to a single lesson a single sentence.The art of economics consists in looking not merely at the immediate but at the longer effects of any act or policy;

it consists in tracing the consequences of that policy not merely for one group but for all groups. (p.2) (1946!)

Free: get the book - http://www.fee.org/library/books/economics-in-one-lesson/ Economics is haunted by more fallacies than any other study known to man.

While every group has certain economic interests identical with those of all groups, every group has also, as we shall see, interests antagonistic to those of all other groups.

Free: get the book - http://www.fee.org/library/books/economics-in-one-lesson/ The BAD economist sees only what is seen

The GOOD economist sees both what is seen and what is unseen

This principle is from 1946. It is still relevant.

But Hazlett got it from Frederic Bastiat in 1850

Free: get the book - http://www.fee.org/library/books/economics-in-one-lesson/ That Which is Seen, and That Which is Not Seen by Frederic Bastiat, 1850In the department of economy, an act, a habit, an institution, a law, gives birth not only to an effect, but to a series of effects. Of these effects, the first only is immediate; it manifests itself simultaneously with its cause - it is seen. The others unfold in succession - they are not seen: it is well for us, if they are foreseen. Between a good and a bad economist this constitutes the whole difference - the one takes account of the visible effect; the other takes account both of the effects which are seen, and also of those which it is necessary to foresee. Now this difference is enormous, for it almost always happens that when the immediate consequence is favourable, the ultimate consequences are fatal, and the converse. Hence it follows that the bad economist pursues a small present good, which will be followed by a great evil to come, while the true economist pursues a great good to come, - at the risk of a small present evil.

A reminder from the beginning of this presentation:Which is also why we will get along fine with an older book (and you will save money):23When you think of the broken window we are actually considering the opportunity cost of an action taken.Thinking about a choice as a tradeoff emphasizes cost as an opportunity forgone.The highest-valued alternative that we give up to get something is the opportunity cost of the action chosen.

24When you (and everyone else) make choices they evaluate or analyze the consequences of making incremental changes in the use of their resources.These incremental changes are:marginal benefits - The value or benefit from pursuing an incremental increase in an activitymarginal costs - The opportunity cost of pursuing an incremental increase in an activity25Lets let MB stand for marginal benefitsandMC represent marginal costsThen here is how you succeed in economic analysis

26The answer to all questions has at their core:

If MB > MC then do it

If MB < MC then dont do it

If MB=MC that is just right!27We act voluntarily and not coerced in our self-interestSelf-interested actions are not necessarily selfish actions.

But if people pursue self-interest, how can the social interest be served?Society creates institutions that create incentivesto behave in the social interest.28And the number one Institution?

the rule of law that protects private property and facilitates voluntary exchange in markets.29Thanks for sticking with this introduction.Dr. Myers
