The nature of bubbles
The nature of bubbles
?   the first recorded speculative (economic)
    bubble
?   a period in the Dutch Golden Age during
    which contract prices for bulbs of the recently
    introduced tulip reached extraordinarily high
    levels and then suddenly collapsed
?   At the peak of tulip mania, in February
    1637, some single tulip bulbs sold for more
    than 10 times the annual income of a skilled
    craftsman
?   The tulip was introduced to Europe in the mid-16th century from
    the Ottoman Empire to became very popular in the United
    Provinces
?   rapidly became a luxury item and a status symbol
?   Growers named their new varieties with exalted titles
?   Tulips grow from bulbs, and can be propagated through both seeds
    and buds. Seeds from a tulip will form a flowering bulb after 7¨C12
    years. When a bulb grows into the flower, the original bulb will
    disappear, but a clone bulb forms in its place, as do several buds.
    Properly cultivated, these buds will become bulbs of their own
?   Tulips bloom in April and May for only about a week, and the
    secondary buds appear shortly thereafter. Bulbs can be uprooted
    and moved about from June to September, and thus actual
    purchases (in the spot market) occurred during these months
?   During the rest of the year, traders signed contracts
    before a notary to purchase tulips at the end of the
    season (effectively futures contracts)
?   Thus created a market for durable tulip bulbs. Short
    selling was banned by an edict of 1610, which was
    reiterated or strengthened in 1621 and 1630, and again in
    1636. Short sellers were not prosecuted under these
    edicts, but their contracts were deemed unenforceable.
?   As the flowers grew in popularity, professional growers
    paid higher and higher prices for bulbs
?   By 1634, in part as a result of demand from the
    French, speculators began to enter the market. In
    1636, the Dutch created a type of formal futures markets
?   Traders met in "colleges" at taverns and buyers were required to
    pay a 2.5% "wine money" fee, up to a maximum of three
    florins, per trade
?   The contract price of rare bulbs continued to rise throughout 1636.
    That November, the contract price of common bulbs without the
    valuable mosaic virus also began to rise in value.
?   no bulbs were actually changing hands, however in February
    1637, tulip bulb contract prices collapsed abruptly and the trade of
    tulips ground to a halt.
?   Neither party paid an initial margin nor a mark-to-market
    margin, and all contracts were with the individual counter-parties
    rather than with the exchange. No deliveries were ever made to
    fulfill these contracts because of the market collapse. This trade
    was centered in Haarlem during the height of a bubonic plague
    epidemic, which may have contributed to a culture of fatalistic
    risk-taking
?   Goods allegedly exchanged for a single bulb of the Viceroy

?   Two lasts of wheat 448?
?   Four lasts of rye 558?
?   Four fat oxen 480?
?   Eight fat swine 240?
?   Twelve fat sheep 120?
?   Two hogsheads of wine 70?
?   Four tuns of beer 32?
?   Two tons of butter 192?
?   1,000 lb. of cheese 120?
?   A complete bed 100?
?   A suit of clothes 80?
?   A silver drinking cup 60?

?   Total 2500?
?   the growing popularity of tulips in the early 17th century
    caught the attention of the entire nation
?   By 1636, tulips were traded on the exchanges of numerous
    Dutch towns and cities. This encouraged trading in tulips by
    all members of society
?   Many individuals grew suddenly rich. A golden bait hung
    temptingly out before the people, and, one after the
    other, they rushed to the tulip marts
?   People were purchasing bulbs at higher and higher
    prices, intending to re-sell them for a profit
?   In February 1637, tulip traders could no longer find new
    buyers willing to pay increasingly inflated prices for their
    bulbs
?   the demand for tulips collapsed, and prices plummeted
?   the panicked tulip speculators sought help from the
    government of the Netherlands, which responded by
    declaring that anyone who had bought contracts to
    purchase bulbs in the future could void their contract
    by payment of a 10 percent fee
?   The mania finally ended with individuals stuck with
    the bulbs they held at the end of the crash¡ªno court
    would enforce payment of a contract, since judges
    regarded the debts as contracted through
    gambling, and thus not enforceable by law
?   Does it question of the efficient market hypothesis?
?   even at its peak the trade in tulips was conducted almost
    exclusively by merchants and skilled craftsmen who
    were wealthy, but not members of the nobility
?   dozens who experienced financial troubles in the time
    period, and even of these cases it is not clear that tulips
    were to blame
?   money had not exchanged hands between buyers and
    sellers. Thus profits were never realized for sellers;
    unless sellers had made other purchases on credit in
    expectation of the profits, the collapse in prices did not
    cause anyone to lose money
?   The increases of the 1630s corresponded with a lull in the
    Thirty Years' War
?   On February 24, 1637, the self-regulating guild of Dutch florists, in a
    decision that was later ratified by the Dutch Parliament, announced
    that all futures contracts written after November 30, 1636 and
    before the re-opening of the cash market in the early Spring, were to
    be interpreted as option contracts
?   This decree allowed someone who purchased a contract to void the
    contract with a payment of only 3.5 percent of the contract price
?   Thus, investors bought increasingly expensive contracts. A
    speculator could sign a contract to purchase a tulip for 100 guilders.
    If the price rose above 100 guilders, the speculator would pocket the
    difference as profit. If the price remained low, the speculator could
    void the contract for only 3? guilders. Thus, a contract nominally
    for 100 guilders, would actually cost an investor no more than 3?
    guilders. In early February, as contract prices reached a peak, Dutch
    authorities stepped in and halted the trading of these contracts
?   that actual sales of tulip bulbs remained at ordinary levels
    throughout the period
?   the "mania" was a rational response to changes in contractual
    obligations
?   Some economists also point to other factors associated with
    speculative bubbles, such as a growth in the supply of
    money, demonstrated by an increase in deposits at the Bank
    of Amsterdam during that period
?   Even though the financial crisis affected very few, the shock
    of tulipmania was considerable. A whole network of values
    was thrown into doubt
?   The idea that the prices of flowers that grow only in the
    summer could fluctuate so wildly in the winter, threw into
    chaos the very understanding of "value
