Well, I don't see possible to separate so easely the real from the Financial. The big problem is acumulated Debts, and I don't believe that more proactive FED could have reduce the crisis to a simple recesion. It is irrelevant for me if the falling demand was first than financial crisis.

There was also a commodity price shock especially the price of oil. The recessions of the mid and late 70's were in part driven by the same phenomenon. The housing bubble burst around 2006 and I believe was contributing negatively to gdp thereafter.

(Not an economist.) There was a big run-up in oil prices in 2007-2008, causing a noticeable increase in transportation costs in North America. Could that, coupled with the trends in household expectations, have triggered the 2008 crisis? Or is this too specific to factor into the model you're describing?

Nick, I updated the post with figures showing NGDP and recessions. The paper I link to in the post looks at expected income and changes in wealth to explain the downturns. It finds these two alone explain most of the decline. Here is the link to the article: [Link here NR]

Dean Baker has commented on this subject before. As usual it is hard to find anything to disagree with in his opinion.....

http://www.ruthgroup.org/wp-content/uploads/2008/09/origins-of-the-financial-crisis-5-4doc.pdf

The only weakness I can find in Dean's arguments is that the housing bubble itself might have masked an employment crisis that would have been inevitable with such a mismatched balance of trade. Spain looks to have been the same.

Yes, Spain looks the same. The same bubble and similar bust. The same excess, imposible to dominante with monetary Policy. But the Big diference of course is the big mistrales of ECB after the crisis.

I suppose that the Sumner's "crazy" Theory requires that there was no bubble at all previus to the crisis. If We asume y bubble and its consequences in huge Debt, we can explain the magnitude of the crisis. If not, We most suppose that all the fault is for the FED.

What did happen in 2008 was that the bubble finally did burst. That was predictable and predicted.

There is a book from Warren Brussee: "The Second Great Depression, Starting 2007, Endng 2020" printed in 2005, based on data until 2003. The guy is still alive, and even has a blog.

That was before the subprime and before the house bubble in the US really took of.

The seeds for that were sawn in the 1990ties, 1998 the latest, by a Greenspan running interest rates too low.

To start his plots at 2005 means that David Beckworth still doesn't have a clue.

I have read Professor Sumner's arguement and discussed it at his blog site.

Prof' Sumner defines money as $100 bills (that is not an exageration). The professor would say that the market crashed because of rational expectations of an ecnomic slow down due to insufficient base money cration by the fed.

I would include most financial assets as money. The rapid fall in asset prices was a destruction of money. The economy slowed because of the crash. The market crashed because markets are unstable. They are not irrational, but they are subject to feedback loops which make them chaotic.

There is also insufficient discussion of what falling asset prices do to debt burdens. Asset prices fall debts stay the same. One of the cures of the malaise is to reduce the real debts. The ways to reduce debts are to pay it off, inflate it away, and default. There has been so much policy effort to prevent bankruptcy and default. We should be encouraging it!

"...while it is a commonplace in intertemporal macroeconomic theory that a decline in expected future nominal income would cause a decline in current desired nominal expenditure ("aggregate demand")..."

I'm trying to get my head around the story David Beckworth is telling re the sources of the recession. Circa 2008, a typical respondent to the Michigan survey was thinking what? "I need to curtail my present expenditure because I expect the Fed will soon adopt a new policy stance that will reduce the rate of future NGDP growth. The rate of price-inflation is not going to fully adjust to reflect the Fed's new stance immediately, so I expect my real income to be below-normal over the net few years. I can't borrow against my future income, so if I want to maintain my customary level of real consumption over the transition period I need to build up a little nest-egg for this purpose starting today."

Is this even close?

"Households' average expectations of their own nominal household income growth isn't exactly the same as expectations of nominal GDP growth."

First, I think you need to get the term "wages" in there somewhere.

Second, falling wage share of national income. See my comment here.

http://worthwhile.typepad.com/worthwhile_canadian_initi/2013/04/begging-the-long-run-question-inflation-variability-vs-ngdp-growth-variability.html?cid=6a00d83451688169e201901b84beb5970b#comment-6a00d83451688169e201901b84beb5970b

You need to do monthly budgeting. For most of the lower and middle class, prices were rising more than wages, and they were using currency denominated debt to make up the difference. Currency denominated debt was being used to prevent price deflation. Price inflation measures overemphasized tradable goods. China was exporting price deflation in tradable goods, but not in college tuition, health insurance, energy, etc.

Brussee made his prediction based on a comparison to Japanese Consumer data.

Japan built their financial time bomb in the 60ties and 70ties, with interest rates pressured low, and then it exploded into their face 1990.

That looked in 1985 like a clever move to give the Japanese industry an advantage compared to the US and Germany (Queisser: Kristallene Krisen 1985. I loved his black sheep tie at the Punktdefekttreffen : - ).

But what they had to do after 1990, kind of following the Krugman advice, has brought them now into such a desparate situation, that they made now their financial "Pearl Harbor decision"

http://www.ft.com/intl/cms/s/0/894422b4-a5d6-11e2-9b77-00144feabdc0.html#axzz2RPEqIIom

We learned from Izzabella Kaminska over Xmas, that it took the Roman Empire 60 years after debasing the currency to then let the inflation destroy the core of their economy.


"Never reason from an expectations change". What caused/allowed expectations to change like that?"

Reality! People saw their jobs being exported to China, saw their jobs being taken by machines, and saw things like if you go on strike, firms will replace you with someone else. They should have seen this back in the 1990's.

"In any case, Scott Sumner's crazy idea that declining actual/expected NGDP is what caused (at least a large part of) the financial crisis, rather than vice versa, is looking a lot less crazy. And maybe it's time to put macro into finance, rather than (just) vice versa."

About the finance part, can banks and bank-like entities increase purchasing power on goods/services and/or financial assets? Yes/No

Luis said: "The big problem is acumulated Debts"

I agree, but good luck getting Scott, Nick, or most other economists to say too much currency denominated debt (both private and gov't) is the problem.

You will need to start by defeating the argument that for every borrower there is a lender.

Yes, but this argument IS true only accontably. It doesn't mean anytning if IS so dificult to reestructure debt.

Sorry, but interest rates were to high back in the 90's and 80's which caused leverage to rocket. Then everybody wanted a piece of it.

Debased currency my rear end. Classic backwards look.

When interest rates are to high leverage and debt surge in the system. It wasn't to mid-2002 when central bank policy finally got loose enough that leverage deceleration started. The leverage boom of 99-2002 was when it was the worst.

David Beckworth claims the basic problem is ordinary households’ inability to deal with debt, which in turn has cut household spending. And his solution? It’s to have the Fed print money and buy up assets owned by the rich. Why the alleged solution has any big effect on the problem eludes me.

genauer: "To start his plots at 2005 means that David Beckworth still doesn't have a clue."

He started his plots in 1978. Which is obvious, if you look at his picture.

Giovanni: current desired consumption depends on current income, but also on expected future income. That's one mechanism. Current desired investment depends on expected future demand, and future demand will (roughly) equal future income. That's a second mechanism. A third might be that willingness and ability to borrow would depend on expected future income.

Ralph: debt is never a problem. Debt/income ratio can sometimes be a problem. Since most debt is nominal (unindexed to inflation), at the aggregate level that means debt/NGDP ratio can be a problem. There are two ways to reduce a ratio: reduce the numerator; increase the denominator. Since we want to increase the denominator anyway, to get NGDP back up to trend, to reduce unemployment, that seems the sensible way to go.

Nick, Thanks for your response. If more QE really does increase real GDP and hence bring unemployment down, I’m all for that. But I’m puzzled as to why giving the wealthy cash in exchange for government debt will greatly increase their spending: they make a small capital gain as a result of QE, but against that, their marginal propensity to consume is low. Plus the REAL PROBLEM (if David Beckworth is right) is lack of confidence amongst LESS WELL OFF households. QE gives that lot no inducement to spend.

But wages/(household debt) surged between 2000-2006. (Debt service also increased strongly and was not strongly correlated to short-term interest rates (i.e. mostly mortgage debt).) One could argue that households were beginning to experience or had expectations of their own financial crisis, which played into the GFC later. With that debt surge, I think it's still hard to argue the direction of causality. Each homeowner making the decision to "cut-back a little" because they just bought a big house with new appliances, makes sense locally, but not in aggregate.

"...current desired consumption depends on current income, but also on expected future income. That's one mechanism. Current desired investment depends on expected future demand, and future demand will (roughly) equal future income. That's a second mechanism. A third might be that willingness and ability to borrow would depend on expected future income."

Think of a classical macro world, with across-the-board instantaneous price adjustment and national income perpetually at potential. In such a world why would suddenly realizing the CB intended to reduce the rate of NGDP growth - which is to say, the rate of inflation - in the near future lead me to curtail my current expenditure? So future nominals will be less than I'd previously expected - la-di-da. As long as future relative prices and my future real income are unchanged no need to revise any of my plans. (Yes, there are all kinds of mechanisms by which reducing the expected inflation rate might elicit a current expenditure response - for example, by reducing the effective rate of taxation on investment income or alleviating the front-end-loading of standard loans - but these effects are likely to be (1) largely expansionary and (2) much smaller in size than what we're talking about here.)

So, if we can't get much expenditure action in a classical macro world, we must be talking about a world with enough price/wage rigidity so the CB expected actions will engineer a recession and thereby reduce my future real income...the anticipation of which leads me to curtail my current expenditure.

BTW Isn't a relative reduction in wages exactly what Sumner has prescribed, to cure the sticky wage problem? Shouldn't we expect nominal wages to lag NGDP to boost employment? In fact David's chart shows NGDP growth exceeding expected income growth 2000-2008.

Nick,

I would recommend a link between your ideas here and Gary Gorton's work on the crisis. He has argued that the crisis was an old fashioned bank run but, most interestingly, he does not believe that Lehman's crash and the ensuing crisis had much of anything to do with the "subprime lending mortgage housing crisis." In other words, he is halfway to your own argument! I believe that the smoking gun in favor of your position would be to show that Lehman's crash and the general financial crash were AT THAT MOMENT caused by falling NGDP expectations. It would be interesting to go through Gorton's work and see if a statistical connection can be detected between his description of Lehman's crash and tight money from falling NGDP expectations. In other words, can it actually be shown statistically that Lehman's crash was caused by the phenomenon that Beckworth describes in his post?

Here's a post by Arnold Kling about this.... http://econlog.econlib.org/archives/2012/07/post_2.html

Best regards.

Nick,

You write:"...current desired consumption depends on current income, but also on expected future income. That's one mechanism. Current desired investment depends on expected future demand, and future demand will (roughly) equal future income. That's a second mechanism. A third might be that willingness and ability to borrow would depend on expected future income."

Alright, but...think of a classical macro world with across-the board instantaneous price adjustment and national income perpetually at potential. Suppose I suddenly realize the CB intends to reduce the growth of NGDP - which is to say, the rate of inflation - in the near future. La-di-da...since this will have no effect on future relative prices or my future real income I have no reason to reduce my current expenditure - or change any of my plans, for that matter. (Yes, there are all kinds of mechanisms - e.g., reducing the effective rate of tax on investment income, alleviating the front-end-loading of standard loans - by which a lessening of expected inflation might itself affect current expenditure. But these effects are (1) largely expansionary and (2) really small compared to the expenditure change we're talking about here.)

So, if we can't get much current expenditure action in a classical macro world, we must be in a world with price/wage rigidity - enough rigidity in fact so that the CB's expected cutailment of NGDP growth is also expected to induce a major recession, thereby reducing my expected future real income. It must be my anticipation of these future income losses that induces me to curtail my current consumption/investment expenditure, thereby shifting the IS curve to the left and moving the recession forward to the here-and-now.

What else could the story be?

From 1992-2000 real median income increased. From 2000- 2004,it fell. It wasn't irrational to expect that this reverse was temporary and to keep up consumer spending by borrowing. Borrowing increases NGDP by transforming credit, which doesn't appear in NGDP into investment that does. Since GDP = GDI = GDE, all sides of the equations increase in lockstep.

For every borrower, there is a lender, but the loan is an asset to the lender. There's no reason for the lender to reduce spending given sufficient liquidity. Increased credit has to increase NGDP. If it didn't then there would be no point in borrowing to invest, since there could be on average no return on investment. This view of credit captures the fundamental distinction between solvency and liquidity, which a pure loanable funds model doesn't.

If additional credit increases NGDP. the net repayment (or default) should correspondingly decrease it. Since 2007 consumer credit has decreased even more than government debt has increased, so that total US debt has actually decreased from 2007-2012.

The US is one of the only developed countries that has actually practiced total economy austerity. The European countries have decreased government spending, and had to borrow to cover the revenue shortfall while achieving no decrease in private sector debt. Their total debt has increased. This is an odd sort of austerity - all pain and no gain.

I think, among other things, that this shows the danger of using NGDP as a representation of the entire economy. It isn't designed for this.

You can also look at total debt / NGDP as a crude measure of financial asset leverage over the real asset economy. We could probably come up with better ones if economists felt it was important enough.


BTW because of the velocity of money, the credit affecting GDP should be 1/2 the increase in the current period + 1/2 the increase in the previous period.

Nick,

I seem to have a comment lost in space. It's about the trend in median income 1992 - 2000 - 2005 related to NGDP and debt. I'd rather not recreate, if I don't have to.

Peter: Stephen has retrieved it. And I just retrieved a couple of Giovanni's.

I'm a bit too tired to respond to comments. But I'm reading them.

Sorry, but there's probably some redundancy in mine...I tried once and then again when the first didn't show up.

Among other things this happened in 2008

M4- excludes T-bills. The M4, M4- divergence looks like a flight to safer assets.

I thought this was common knowledge -- I.e. the bursting of the housing ponzi scheme clearly implies #2). The crisis was a banking crisis, which was the result of the deterioration of the bank's assets, namely mortgage loans. This happened as a result of the declining house prices from their bubble values and the corresponding decrease in residential investment, as no one is going to pour money into an asset class whose overall value is going to decline. It was not the other way around -- e.g. a banking crisis happens for no reason whatsoever, causing house prices and consequently residential investment to decline.

In terms of what the CB could do to prevent house prices from rationalizing, they could cut rates to zero right away and lift leverage requirements and capital adequacy requirements. That *might* have been able to distort house prices even further and delay bank recognition of losses for a bit.

For #4 try this:

Tight credit

derivative market crash

durable goods orders show some combination the expectations of producers of consumer goods and availability of credit to them. In either case they change their orders for means of production indicating either they expect less consumer demand or they can't finance their production or both.

"Since we want to increase the denominator anyway, to get NGDP back up to trend, to reduce unemployment, that seems the sensible way to go."

There should be a model where raising prices causes real GDP to fall lowering employment. If real wages being too low (probably negative) caused the recession then trying to make real wages negative by raising prices may make the situation worse. I also don't believe trying to make firms more profitable thru price increases will help employment and/or wages when corporate profits as % of GDP are at or near a record high.

About real earnings being negative:

http://advisorperspectives.com/dshort/updates/Median-Household-Income-Update.php

I believe price inflation measured by a lower/middle person's budget is about 1% to 2% higher than CPI. That would make the charts look worse. I think that is where Peter N got his first chart.

"What happened in 2008?"

It was a currency denominated debt crisis that led to the amount of medium of account (MOA)/medium of exchange (MOE) to fall creating a shortage.

Ralph Musgrave said: "But I’m puzzled as to why giving the wealthy cash in exchange for government debt will greatly increase their spending: they make a small capital gain as a result of QE, but against that, their marginal propensity to consume is low."

Exactly. The central bank buys some bonds from a bank. The bank buys some bonds from Apple and Warren Buffett. I don't see either one spending to consume or spending to invest, just some financial assets being exchanged (the demand deposits just sit in Apple's and Buffett's checking accounts with zero velocity in the real economy). If lower interest rates (the central bank will probably overpay) don't get the savers to spend and no one else goes into currency denominated debt, then the economy is basically going nowhere. In other words, both Apple and Buffett want to continue to save (not consume and not invest).

"Plus the REAL PROBLEM (if David Beckworth is right) is lack of confidence amongst LESS WELL OFF households. QE gives that lot no inducement to spend."

It is not about confidence. It is about reality smashing their previous incorrect assumptions and straining the monthly budget.

Leo said: "There was a big run-up in oil prices in 2007-2008, causing a noticeable increase in transportation costs in North America."

I'd say it contributed. That was one price going up more than wages, straining monthly budgets. It also affected the budgets of other entities.

home equity, consumer debt and federal debt. Fall in equity precedes fall in debt. Increasing federal debt effectively transfers the debt to the public sector. Total debt decreases. This is austerity that at least sort of works. In Europe you have increasing government debt and increasing consumer debt. That's austerity that doesn't work.

As part of what happened in 2008 note in the graph above the huge drop in financial sector credit. That has to be extremely contractionary. And it's still going down. It's amazing the economy is doing as well as it is.

I think there may be some value in having these charts together like this. This one is from one from FT Alphaville that DeLong included in a paper he put up today on 2008 and fiscal policy. The subject of the chart is safe assets.

Peter N said: "For every borrower, there is a lender, but the loan is an asset to the lender."

How are you defining borrower and lender?

If I loan you $1000, I create an $1000 asset, the loan, in place of a $1000 cash asset and you create a $1000 cash asset and a $1000 liability for the loan. In a sense nothing has happened, since both sides have the same net worth before and after.

If I were a bank, however, you would two get pieces of paper (conceptually). One would say you owed me $1000 and the other that I owed you $1000. You would give me the same. However since I was a bank, my liability (your deposit) is money. You could, of course, ask me to satisfy it in cash, but then you would deposit it in some other bank and they would have the liability (deposit).

For each borrower there is a lender because financial assets and liabilities are created pairwise. The difference is that if I weren't a bank, my IOU to you wouldn't be very good money (would not be very liquid).

Moreover, as a bank, I can lend as much as I like subject to some not very restrictive reserve requirements and a more restrictive capital to assets at risk ratio. A bank will lend up to it's capital limit (with a small margin for prudence) provided that it can find credit-worthy borrowers willing to pay a satisfactory premium.

When banks are lending less than they could, it means either that there is insufficient demand for loans at the premium or that there is a lack of borrowers who meet the banks' credit standards.

The Fed can control bank lending by changing the rate it charges for lending reserves, but it doesn't directly restrict the amount of reserves it lends, and banks can borrow reserves elsewhere. So money is endogenous, but the Fed can restrict the amount created to the extent it controls the cost of funds and is willing to raise short term interest rates.

Note that as we go up the money hierarchy from M1 to M4, the Fed's control becomes clumsier. It can be unwilling to go to the necessary lengths to control something like M4, for both economic and political reasons.

The important point is that increased credit becomes increased investment and adds to GDP, but the way GDP is calculated hides this effect. GDP = GDI = GDE is an accounting identity, and it's dangerous to draw conclusions from it about aspects of the economy it deliberately ignores.

For this stuff I highly recommend Monetary Economics by Godley and Lavoie, which is stock and flow correct. The software to implement their models is freely available.

As someone once said:

"There's something really wrong with the way we do short run macroeconomics. We focus all our attention on the output of newly-produced goods and services. That's what we call "Y". We talk about Aggregate Demand and Aggregate Supply, and what we mean by AD and AS is the demand and supply of those same newly-produced goods and services.

Keynesians then go on to divide Y into C+I+G, and C+S+T. Monetarists talk about MV=PY. Both agree that a recession is a fall in Y, caused by a drop in demand for Y.

But a moment's reflection tells you this is wrong. It's not just new stuff that is harder to sell in a recession; it's old stuff too. New cars and old cars. New houses and old houses. New paintings and old paintings. New furniture and antique furniture. New machine tools and old machine tools. New land and old land."

http://worthwhile.typepad.com/worthwhile_canadian_initi/2011/12/why-y.html

Peter N,

Y is divided into Personal Consumption Expenditures + Business Investment + Government Expenditures + Net Exports ( Keynesian style )

Personal Consumption Expenditures = Business Investment * Markup (Value added, profits, etc) + Purchase of existing goods from prior periods

The problem is not in Y, it is a problem in separating the nominal, real, AND depreciated value of Y.

Using the car example. It is relatively easy to track the prices of new cars and guage an inflation rate on new cars. Used cars are trickier because of depreciation. And so you really have three prices for a used car - it's nominal price, its inflation adjusted price, and its depreciation adjusted price. A car manufactured in 2010 sold today will typically sell for less in a year's time even if it has the exact same mileage, wear, and tear.

Used cars don't exist. The car itself is an existing good. A car can only be produced once. GDP only takes account of added value, where value is basically labor cost. That allows GDP to equal GDI, since all goods are investment when they are produced. The investment value is the cost, which is simultaneous. Since cost = cost, you have an identity, even though the goods produced can't possibly be the same goods for which the costs were incurred. The methodology ignores the fact that production takes time.

The closer you look at GDP, the more you realize what a poor basis it is for macroeconomics.

Peter N.

"GDP only takes account of added value..."

No it doesn't.

Nick wrote: ". David's graph starts to head south in 2005. It's just a bit too early for comfort, if you want to say that declining expected nominal income is what caused the 2008 financial crisis and 2009 recession."

You should know better than to admit something like that in public, Nick, as it inspired this sophomoric post.

With used cars, what's counted is the dealers added value. The dealership is a business, so its output has to be part of GDP, but its sort of a service.

Everything in GDP eventually maps to the cost of the labor that produced it. Otherwise GDI = GDP wouldn't be an identity. Since the used car dealer is a business, its payroll direct and indirect makes a contribution to GDP.

If you as an individual sell your car, it doesn't contribute to GDP. If I'm reading this correctly, the amount the dealership pays for the used car isn't income to the seller, so it won't appear in GDI or GDP. Likewise it shouldn't appear in GDE. It couldn't be a consumer expenditure to the buyer from the dealership unless it was consumer income for the seller to the dealership, otherwise the accounts wouldn't balance.

The dealer's added value has to be an expenditure for the buyer so the dealer's labor costs can be income for the dealer's employees. Again, otherwise the books wouldn't balance.

GDI = GDP = GDE is an identity by definition.

Peter N,

Most used vehicles orginate as trade ins. And so the number of people selling their car on their own is insignificant compared to the number of people that trade in their car for a newer model. The used cars are then sold back to the public by used car dealers. The sale of the used car does not show up in the income account for the seller because the net of the transaction (new car price paid - used car price received) is positive.

When a business sells anything from inventory to a consumer, this is consumer expenditure and business disinvestment. This mostly doesn't affect GDP. I say mostly because the rules are complicated. This what the BEA says:

"
Net transactions

Net transactions between persons and other sectors of the economy primarily consist of the wholesale value of purchases by persons from dealers less sales by persons to dealers (either directly or as trade-ins). In addition, transactions may occur between persons and businesses other than dealers (such as the sale of scrapped vehicles), government, and nonresidents. Transactions among persons are intrasectoral and so do not affect PCE.

For both benchmark and nonbenchmark years, estimates of net transactions are developed by valuing the annual change in unit stocks of used motor vehicles held by persons, rather than by explicitly taking into account each type of transaction listed above. Year end unit stocks of used autos and of used light trucks are estimated for each year of original sale (vehicles greater than 11 years old are grouped together) using annual data on new motor vehicle purchases and retention information developed from R.L. Polk & Co. data on vehicles in use by model year. Unit stocks held by business are based on business purchases of new motor vehicles and on retention rates for rental vehicles (6–18 months), leased vehicles (2–4 years), and other business vehicles (1–9 years). Unit stocks held by government are based on government purchases of new vehicles and on assumed retention rates. Stocks held by persons are then calculated as the residual.

Changes in the unit stocks of autos and of light trucks held by persons reflect purchases of new vehicles, scrappage of old vehicles, and net unit transactions other than scrappage. Purchases of new autos and of light trucks by persons are estimated separately (see the section “New motor vehicles”). Scrapped units are calculated by age of vehicle as a proportion of total vehicle scrappage; this proportion is assumed to be equal to the ratio of the unit stock held by persons to the total unit stock. Net unit transactions other than scrappage is then calculated as the residual.

The changes in unit stocks, grouped by age, are then valued at wholesale prices.The average wholesale value for each age group of used autos and of used light trucks is based on average auction prices by model year from ADESA. Scrapped units by age are valued at 8 percent of the wholesale price.

Current quarterly and monthly estimates of net transactions are extrapolated from the annual estimates, using data on retail sales of used car dealers from the monthly retail trade survey. The estimates of real net transactions are prepared by deflation, using the PI for used autos and trucks.

"For each borrower there is a lender because financial assets and liabilities are created pairwise."

That is one way. I'd like to know what Nick thinks about that.

"If I loan you $1000, I create an $1000 asset, the loan, in place of a $1000 cash asset and you create a $1000 cash asset and a $1000 liability for the loan. In a sense nothing has happened, since both sides have the same net worth before and after.

If I were a bank, however, you would two get pieces of paper (conceptually). One would say you owed me $1000 and the other that I owed you $1000. You would give me the same. However since I was a bank, my liability (your deposit) is money. You could, of course, ask me to satisfy it in cash, but then you would deposit it in some other bank and they would have the liability (deposit)."

So are you saying borrowing $1,000 from a friend is the same as borrowing $1,000 from a bank?

"The Fed can control bank lending by changing the rate it charges for lending reserves, but it doesn't directly restrict the amount of reserves it lends, and banks can borrow reserves elsewhere. So money is endogenous, but the Fed can restrict the amount created to the extent it controls the cost of funds and is willing to raise short term interest rates."

I'd change "can control bank lending" to "can attempt to control bank lending".

Plus, what is your definition of money?

"So are you saying borrowing $1,000 from a friend is the same as borrowing $1,000 from a bank?"

No. The accounting works the same way, but the moneyness of the two liabilities is different. You can't write a check on my liability as a lender and have it universally accepted, whereas you can do so with the bank's liability, which is usually known as a deposit.

Money is anything that possesses enough moneyness to have economic significance. You can measure moneyness by the calculating the asset's liquidity premium (which isn't always possible). J P Koning is the blogging guru for thia topic: http://jpkoning.blogspot.com/

The aggregates M0 - M4 are commonly used to track the supply of money. Divisia M3, M4- and M4 are a welcome addition to the family of aggregates, since the Fed killed off the old M3 (which had problems, in any case).

I think that "can attempt to limit bank lending" is better. The Fed's ability to encourage bank lending appears to be much weaker. It is worth noting that trends in the larger aggregates tend to lead M0, not trail it.

IIR Minsky said something like: "Anybody can issue money, the trick is to get other people to accept it."

Peter N,

Governments figured out how to do that a long time ago. They levy taxes.

This is change in debt as a percent of GDP flow charted against change in GDP. Note the close correlation.

It's not the stock of national debt that has an immediate effect om GDP, it's the flow of total debt.

TMCDO is total credit market debt owed
HSTCMDODNS is total credit market debt owed by the household sector
TCMDODNS is total credit market debt owed by the domestic non-financial sector
TCMDODFS is total credit market debt owed by the domestic financial sector

"No. The accounting works the same way, but the moneyness of the two liabilities is different. You can't write a check on my liability as a lender and have it universally accepted, whereas you can do so with the bank's liability, which is usually known as a deposit."

What if you borrow $1,000 in currency from a friend?

W. Peden,

"The bank looks to borrow reserves from other banks to meet its liabilities." So the textbooks say, but in reality? In reality reserve requirements aren't very restrictive. Banks have other sources of funds than demand deposits. The real limits on lending are the ratio of capital to assets at risk, the cost of funds, the availability of credit-worthy borrowers. And, of course, banks sometimes would rather invest than lend.

I have papers from economists about this going back 15 or 20 years. The Fed influences bank lending by using the discount rate to increase or decrease the cost of funds. Assuming a sloping demand curve for loans, and a fairly stable bank margin, increasing the discount rate will decrease the demand for loans as long as banks don't have cheaper sources of funding.

And, of course, as you go up the hierarchy of aggregates from M1 to M4, the Fed's fine tuning ability gets progressively weaker.

I'm curious why imcnoe inequality is not mentioned -- it seems to be the elephant in the room, both in the U.S. and in China. In that situation, you are not going to get rid of excessive patience. It's almost impossible for the top 1% to consume that much -- they are more or less immune to interest rates. But if you believe in a consumption function (a.k.a Carroll and Kimball -- 1996) that is strictly concave in wealth, then re-distribution should be the cure for excessive patience, just as (I believe) the structural shifts towards top earners was the cause of the excessive patience. And better imcnoe security would also help.
