THE IMPORTANCE OF FINANCIAL MARKETS

Financial Markets (or the ability to borrow and lend) improves welfare in 2 ways.Efficiently allocates investible funds among

alternative investments. Provide the ability to borrow and lend money

allows people to adjust spending patterns over time.

Therefore, access to Financial Markets makes people better off.

MILITARY EXPENDITURES.

U.S. military spending is large compared to GDP and is enormous compared to other countries.

“As many frustrated Americans who have joined the Tea Party realize, we cannot stand against big government at home while supporting it abroad.

We cannot talk about fiscal responsibility while spending trillions on occupying and bullying the rest of the world. We cannot talk about the budget deficit and spiraling domestic spending without looking at the costs of maintaining an American empire of more than 700 military bases in more than 120 foreign countries.

We cannot pat ourselves on the back for cutting a few thousand dollars from a nature preserve or an inner-city swimming pool at home while turning a blind eye to a Pentagon budget that nearly equals those of the rest of the world combined.”

The views from atop Los Angeles Unified School District's downtown headquarters are sweeping: Disney Hall, the Music Center complex, iconic high-rise buildings that make up the L.A. skyline.

Inside the 29-story building, more than 3,400 employees filter through LAUSD's main offices every week. The triangular, 928,000-square-foot tower at 333 S. Beaudry Ave. had historically been difficult to lease while owned by Bank of America. It was purchased and renovated by LAUSD in 2001 for $154 million.

But even today, according to a top LAUSD official, the building seems too ostentatious in light of budget cuts and other financial issues the country's second-largest public school district is grappling with.

But Superintendent David Brewer III maintained that Beaudry should not be viewed as a typical corporate building, saying it lacks the granite, fine wood and other trappings of some of downtown's more grandiose skyscrapers.

"It's pretty austere," Brewer said, adding that his own offices are adequate.

He said that while $154 million might seem pricey for the purchase and rehabilitation of the building, it is far less than the cost of leasing space downtown for all of the district's administrators and support staff. Brewer said he hopes the building eventually will come to be seen as a symbol of efficiency as he reduces the size of the central administration and consolidates leased space at other downtown locations into Beaudry.

"It will be a symbol of success versus a symbol of bureaucracy. We'll consolidate all in one and save a fortune, and that's the ultimate in decentralization.

Obama Officials Defend Solar Loan to Bankrupt Firm as Emails Show Past Concerns

Obama administration officials on Wednesday defended a $528 million loan to a solar-panel company that went bankrupt this month, claiming the firm fell victim to global economic trends but that federal investment in alternative energy must continue. 

The testimony came as Republican and Democratic lawmakers raised sharp questions about the decision that ultimately left taxpayers on the hook for millions, and as newly released emails show administration officials were raising doubts about the loan proposal to Solyndra months before it was finalized. 

But emails released by the House Energy and Commerce Committee show that the relevant credit committee decided "not to engage in further discussions with Solyndra" in the final days of the Bush administration. After the change in administration, officials restarted the loan review process for Solyndra. 

One Republican aide said the emails released as part of that probe show the White House was more concerned with press events surrounding the loan than the soundness of Solyndra. The aide said "corners were cut." 

The emails at least show budget analysts felt rushed by the White House to review the loan guarantee in time for an announcement by Vice President Biden in September 2009. 

The concerns flared in August 2009, when staff with the Energy Department wrote of a "major outstanding issue," relating to the project's solvency. They noted an estimate said the project would run out of cash in September 2011. 

But other administration officials presumed the parent company, as well as private investors, would cushion the project and ensure its completion. 

The company filed for bankruptcy this month.

President Obama visited Solyndra in May 2010, heralding the company as “leading the way toward a brighter and more prosperous future.” He also cited it as a success story from the government’s $787 billion economic stimulus package.

“Less than a year ago, we were standing on what was an empty lot.  But through the Recovery Act, this company received a loan to expand its operations,” Obama said at the time. “This new factory is the result of those loans.”

In 2009, the Obama administration fast-tracked Solyndra’s loan application, later awarding it $535 million in guarantees from the stimulus funds.

The deal later came under scrutiny from independent government watch dogs and members of Congress, which said the administration had bypassed key taxpayer protections in a rush to approve the funds — claims the administration has denied.

The efficient allocation, i.e. the allocation that would maximize social welfare, would be to fund the projects with the highest rate or return and leave the ones with lower (or negative) rates of return unfunded.

In a free or unregulated market, this is exactly the allocation that would occur because people investing their own money would seek out the projects with the highest returns.

Adding uncertainty into the mix would not change this result.

FREE MARKETS AND EFFICIENT ALLOCATIONS Generally speaking, loanable funds will be allocated

efficiently if decisions are left in the hands of those who will be rewarded financially if funds are allocated correctly and penalized financially if funds are incorrectly allocated.

This does not mean that every investment funded by private investors will be profitable or able to repay money borrowed because no one can foresee the future.

Private investors will make mistakes but when they do, they alone will suffer the consequences.

Gross misallocation of loanable funds generally occur when the person making the decision about whom to lend to is not rewarded for choosing wisely and not punished for choosing poorly.

http://www.nytimes.com/2010/09/09/business/global/09trade.html In both cases, if producing electricity using wind or the sun was the

lowest cost method of producing power, no government subsidy would be necessary to “promote” the industry. If a solar panel costs $100,000 to produce and produces a flow of

electricity worth $50,000 over its life, subsidizing its production reduces social welfare.

If a solar panel costs $100,000 to produce and produces a flow of electricity worth $200,000 over its life, no subsidy is necessary.

The main beneficiary of the subsidies are purchasing countries like the U.S.

The inter temporal budget constraint shows combinations of consumption now and in the future that are attainable with a certain flow of income and access to financial markets, i.e. the ability to borrow and lend money at the current interest rate.

The present value of the person’s income stream is the horizontal intercept, i.e. what is the maximum amount of consumption the person given his stream of income and access to financial markets, i.e. the ability to borrow and/or lend at market interest rate.

The future value of a person’s income stream is the vertical intercept, i.e. what is the maximum amount of consumption he could engage in given his stream of income and access to financial markets.

REAL AND NOMINAL INTEREST RATES Nominal interest rate makes no allowance for

inflation

Real interest rate is adjusted for changes in price level so it more accurately reflects the cost of borrowing

Ex ante real interest rate is adjusted for expected changes in the price level

Ex post real interest rate is adjusted for actual changes in the price level

FIGURE 1 REAL AND NOMINAL INTEREST RATES (THREE-MONTH TREASURY BILL), 1953–2008

Sources: Nominal rates from www.federalreserve.gov/releases/H15. The real rate is constructed using the procedure outlined in Frederic S. Mishkin, “The Real Interest Rate: An Empirical Investigation,” Carnegie-Rochester Conference Series on Public Policy 15 (1981): 151–200. This procedure involves estimating expected inflation as a function of past interest rates, inflation, and time trends and then subtracting the expected inflation measure from the nominal interest rate.

What does it tell you about inflation that the nominal rate is above the real rate.?

2 MODELS USED TO PREDICT AND UNDERSTAND CHANGES IN INTEREST

RATES

•Basic supply and demand analysis in the bond market.

•Liquidity Preference Model (Keynesian)

Page 37: C HAPTER 4 Understanding Interest Rates. A DMINISTRATIVE D ETAILS. Next week we will run the interest rate experiment from aplia.com. There is a homework.

UNDERSTANDING WHAT CAUSES CHANGES IN INTEREST RATES.

Use basic supply and demand analysis in the bond market.

Assume that there is only one type of bond—a simple discount bond with a face value of $1000.

The price of bonds determines the interest rate and the bond price is inversely related to interest rate.

What happens when bond prices are below the equilibrium price.

For any one year discount bond

i = F - P

PF = Face value of the discount bond

P = current price of the discount bond

The yield to maturity equals the increase

in price over the year divided by the initial price.

As with a coupon bond, the yield to maturity is

negatively related to the current bond price.

If the price of a discount bond with a face value of $1000 is $1000 then the interest rate is zero

If the price of a discount bond with a face value of $1000 is $800 then $800 is being lent, $200 interest is being paid and the interest rate is 25%

UNDERSTANDING WHAT CAUSES CHANGES IN INTEREST RATES.

• Suppose the demand for bonds increases?

DETERMINING THE QUANTITY DEMANDED OF AN ASSET

Analysis of changes in interest rates using The Supply and Demand for bonds requires identifying what causes shifts in the supply and demand curves and doing simple supply and demand analysis.

List of factors that can affect the demand for bonds. Wealth: the total resources owned by the individual, including all

assets

Expected Return: the return expected over the next period on one asset relative to alternative assets

Risk: the degree of uncertainty associated with the return on one asset relative to alternative assets

Liquidity: the ease and speed with which an asset can be turned into cash relative to alternative assets

Page 41: C HAPTER 4 Understanding Interest Rates. A DMINISTRATIVE D ETAILS. Next week we will run the interest rate experiment from aplia.com. There is a homework.

THEORY OF ASSET (BOND) DEMAND

Holding all other factors constant:1. The quantity demanded of an asset is positively

related to wealth

2. The quantity demanded of an asset is positively related to its expected return relative to alternative assets

3. The quantity demanded of an asset is negatively related to the risk of its returns relative to alternative assets

4. The quantity demanded of an asset is positively related to its liquidity relative to alternative assets

SUPPLY AND DEMAND FOR BONDS

• At lower prices (higher interest rates), ceteris paribus, the quantity demanded of bonds is higher: an inverse relationship

• At lower prices (higher interest rates), ceteris paribus, the quantity supplied of bonds is lower: a positive relationship

MARKET EQUILIBRIUM

Occurs when the amount that people are willing to buy (demand) equals the amount that people are willing to sell (supply) at a given price

Bd = Bs defines the equilibrium (or market clearing) price and interest rate.

When Bd > Bs , there is excess demand, price will rise and interest rate will fall

When Bd < Bs , there is excess supply, price will fall and interest rate will rise

SHIFTS IN THE DEMAND FOR BONDS

Wealth: in an expansion with growing wealth, the demand curve for bonds shifts to the right

Expected Returns: higher expected interest rates in the future lower the expected return for long-term bonds, shifting the demand curve to the left

Expected Inflation: an increase in the expected rate of inflations lowers the expected return for bonds, causing the demand curve to shift to the left

Risk: an increase in the riskiness of bonds causes the demand curve to shift to the left

Liquidity: increased liquidity of bonds results in the demand curve shifting right

A bail-out for Greece is just the beginningBy Martin WolfPublished: May 4 2010 20:13 | Last updated: May 4 2010 20:13

Desperate times; desperate measures. After months of costly delay, the eurozone has come up with an enormous package of support for Greece. By bringing in the International Monetary Fund, at Germany’s behest, it has obtained some additional resources and a better programme. But is it going to work? Alas, I have huge doubts.

So what is the programme? In outline, it is a package of €110bn (equivalent to slightly more than a third of Greece’s outstanding debt), €30bn of which will come from the IMF (far more than normally permitted) and the rest from the eurozone. This would be enough to take Greece out of the market, if necessary, for more than two years. In return, Greece has promised a fiscal consolidation of 11 per cent of gross domestic product over three years, on top of the measures taken earlier, with the aim of reaching a 3 per cent deficit by 2014, down from 13.6 per cent in 2009. Government spending measures are to yield savings of 5¼ per cent of GDP over three years: pensions and wages will be reduced, and then frozen for three years, with payment of seasonal bonuses abolished. Tax measures are to yield 4 per cent of GDP. Even so, public debt is forecast to peak at 150 per cent of GDP.

In important respects, the programme is far less unrealistic than its intra-European predecessor. Gone is the fantasy that there would be a mild economic contraction this year, followed by a return to steady growth. The new programme apparently envisages a cumulative decline in GDP of about 8 per cent, though such forecasts are, of course, highly uncertain. Similarly, the old plan was founded on the assumption that Greece could slash its budget deficit to less than 3 per cent of GDP by the end of 2012. The new plan sets 2014 as the target year.

Have your say on Martin Wolf’s column and read contributions by leading economists

Two other features of what has been decided are noteworthy: first, there is to be no debt restructuring; and, second, the European Central Bank will suspend the minimum credit rating required for the Greek government-backed assets used in its liquidity operations, thereby offering a lifeline to vulnerable Greek banks.

So does this programme look sensible, either for Greece or the eurozone? Yes and no in both cases.

Let us start with Greece. It has now lost access to the markets (see chart). Thus, the alternative to agreeing to this package (whether or not it can be implemented) would be default. The country would then no longer pay debt interest, but it would have to close its primary fiscal deficit (the deficit before interest payments), of 9-10 per cent of GDP, at once. This would be a far more brutal tightening than Greece has now agreed. Moreover, with default, the banking system would collapse. Greece is right to promise the moon, to gain the time to eliminate its primary deficit more smoothly.

Page 57: C HAPTER 4 Understanding Interest Rates. A DMINISTRATIVE D ETAILS. Next week we will run the interest rate experiment from aplia.com. There is a homework.

Yet it is hard to believe that Greece can avoid debt restructuring. First, assume, for the moment, that all goes to plan. Assume, too, that Greece’s average interest on long-term debt turns out to be as low as 5 per cent. The country must then run a primary surplus of 4.5 per cent of GDP, with revenue equal to 7.5 per cent of GDP devoted to interest payments. Will the Greek public bear that burden year after weary year? Second, even the IMF’s new forecasts look optimistic to me. Given the huge fiscal retrenchment now planned and the absence of exchange rate or monetary policy offsets, Greece is likely to find itself in a prolonged slump. Would structural reform do the trick? Not unless it delivers a huge fall in nominal unit labour costs, since Greece will need a prolonged surge in net exports to offset the fiscal tightening. The alternative would be a huge expansion in the financial deficit of the Greek private sector. That seems inconceivable. Moreover, if nominal wages did fall, the debt burden would become worse than forecast.

Willem Buiter, now chief economist at Citigroup, notes, in a fascinating new paper, that other high-income countries, notably Canada (1994-98), Sweden (1993-98) and New Zealand (1990-94), have succeeded with fiscal consolidation. But initial conditions were much more favourable in these cases. Greece is being asked to do what Latin America did in the 1980s. That led to a lost decade, the beneficiaries being foreign creditors. Moreover, as creditors are now paid to escape, who will replace them? This package will surely fail to return Greece to the market, on manageable terms, in a few years. More money will be needed if debt restructuring is unwisely ruled out.

For other eurozone members, the programme prevents an immediate shock to fragile financial systems: it is overtly a rescue of Greece, but covertly a bail-out of banks. But it is far from clear that it will help other members now in the firing line. Investors could well conclude that the scale of the package required for tiny Greece and the overwhelming difficulty of agreeing and ratifying it, particularly in Germany, suggest that further such packages are going to be elusive. Other eurozone members might well end up on their own. None is in as bad a condition as Greece and none has shown the same malfeasance. But several have unsustainable fiscal deficits and rapidly rising debt ratios (see chart). In this, their situation does not differ from that of the UK and US. But they lack the same policy options.

This story, in short, is not over.

For the eurozone, two lessons are clear: first, it has a clear choice – either it allows sovereign defaults, however messy, or it creates a true fiscal union, with strong discipline and funds sufficient to cushion adjustment in crushed economies – Mr Buiter recommends a European Monetary Fund of €2,000bn; and, second, adjustment in the eurozone is not going to work without offsetting adjustments in core countries. If the eurozone is willing to live with close to stagnant overall demand, it will become an arena for beggar-my-neighbour competitive disinflation, with growing reliance on world markets as a vent for surplus. Few are going to like this outcome.

The crises now unfolding confirm the wisdom of those who saw the euro as a highly risky venture. These shocks are not that surprising. On the contrary, they could have been expected. The fear that yoking together such diverse countries would increase tension, rather than reduce it, also appears vindicated: look at the surge of anti-European sentiment inside Germany. Yet, now that the eurozone has been created, it must work. The attempted rescue of Greece is just the beginning of the story. Much more still needs to be done, in responding to the immediate crisis and in reforming the eurozone itself, in the not too distant future. [email protected]

There are two main categories of assets that people use to store

their wealth: money and bos s d d

nds.

Total wealth in the economy = B M = B + M

Rearranging: B - B = M - M

If the market for money is in equilibrium (M = M ),

then the bond market is also in equilibrium (B = B ).

DEMAND FOR MONEY IN THE LIQUIDITY PREFERENCE FRAMEWORK

Why is the demand for money downward sloping? As the interest rate increases:

The opportunity cost of holding money increases… The relative expected return of money decreases…

…and therefore the quantity demanded of money decreases.

The higher the rate of interest the less money you will demand because by holding money you forego interest.

EVERYTHING ELSE REMAINING EQUAL?

Liquidity preference framework leads to the conclusion that an increase in the money supply will lower interest rates------but the liquidity effect and an increase in the price level causes counteracting effects. Income effect finds interest rates rising because increasing

the money supply is an expansionary influence on the economy (the demand curve shifts to the right).

Price-Level effect predicts an increase in the money supply leads to a rise in interest rates in response to the rise in the price level (the demand curve shifts to the right).

Expected-Inflation effect shows an increase in interest rates because an increase in the money supply may lead people to expect a higher price level in the future (the demand curve shifts to the right).

FIGURE 10 RESPONSE TO A CHANGE IN THE MONEY SUPPLY

Whether an increase in the money supply will increase or decrease the interest rate depends on the relative strength of the counteracting forces, i.e. income effect, price level effect, and expected inflation effect.

PRICE-LEVEL EFFECT AND EXPECTED-INFLATION EFFECT

A one time increase in the money supply will initiate a chain of events that will effect interest rates over time as the relative strength of two effects changes. A one time increase in the money supply will cause prices to rise to a

permanently higher level by the end of the year. The interest rate will rise via the increased prices.

Price-level effect remains even after prices have stopped rising.

A rising price level will raise interest rates because people will expect inflation to be higher over the course of the year. When the price level stops rising, expectations of inflation will return to zero.

Expected-inflation effect persists only as long as the price level continues to rise.

EXPECTATIONS THEORY

The interest rate on a long-term bond will equal an average of the short-term interest rates that people expect to occur over the life of the long-term bond

Buyers of bonds do not prefer bonds of one maturity over another; they will not hold any quantity of a bond if its expected return is less than that of another bond with a different maturity

Bond holders consider bonds with different maturities to be perfect substitutes

EXPECTATIONS THEORY: EXAMPLE

Let the current rate on one-year bond be 6%.

You expect the interest rate on a one-year bond to be 8% next year.

Then the expected return for buying two one-year bonds averages (6% + 8%)/2 = 7%.

The interest rate on a two-year bond must be 7% for you to be willing to purchase it.

EXPECTATIONS THEORY

Explains why the term structure of interest rates changes at different times

Explains why interest rates on bonds with different maturities move together over time (fact 1)

Explains why yield curves tend to slope up when short-term rates are low and slope down when short-term rates are high (fact 2)

Cannot explain why yield curves usually slope upward (fact 3)

SEGMENTED MARKETS THEORY

Bonds of different maturities are not substitutes at all

The interest rate for each bond with a different maturity is determined by the demand for and supply of that bond

Investors have preferences for bonds of one maturity over another

If investors generally prefer bonds with shorter maturities that have less interest-rate risk, then this explains why yield curves usually slope upward (fact 3)

LIQUIDITY PREMIUM & PREFERRED HABITAT THEORIES

The interest rate on a long-term bond will equal an average of short-term interest rates expected to occur over the life of the long-term bond plus a liquidity premium that responds to supply and demand conditions for that bond

Bonds of different maturities are partial (not perfect) substitutes

PREFERRED HABITAT THEORY

Investors have a preference for bonds of one maturity over another

They will be willing to buy bonds of different maturities only if they earn a somewhat higher expected return

Investors are likely to prefer short-term bonds over longer-term bonds

LIQUIDITY PREMIUM AND PREFERRED HABITAT THEORIES

Interest rates on different maturity bonds move together over time; explained by the first term in the equation

Yield curves tend to slope upward when short-term rates are low and to be inverted when short-term rates are high; explained by the liquidity premium term in the first case and by a low expected average in the second case

Yield curves typically slope upward; explained by a larger liquidity premium as the term to maturity lengthens
