WHEN THE DOLLAR LOST GOLD AND GAINED OIL

In 1973, oil seemed poised to bring the dollar to its knees. Almost the opposite happened: the break with gold and the oil shock ended up cementing the dollar at the center of global finance. The Soviet Union had a great, once-in-a-lifetime opportunity to put its enormous oil profits to good use. It threw that opportunity away, and history took a different course—one that continued through the collapse in 1991 and beyond. (Testo in italiano)

ABSTRACT

The Yom Kippur War did not bring Bretton Woods to an end: the fixed-exchange-rate system had already collapsed in March 1973. The crisis had been prepared by U.S. inflation, the buildup of dollar liabilities abroad, and the growth of the Eurodollar market, all of which made gold convertibility increasingly difficult to sustain. The
closing of the gold window and the subsequent abandonment of fixed parities transformed the Gold Exchange Standard into a de facto dollar standard based on fiat money. The October 1973 war and the political use of oil then turned an already open monetary crisis into a worldwide energy and financial crisis. The connection, however, was not linear: fiscal and monetary policies, expectations and nominal rigidities,
supply shocks, exchange rates, and international credit operated as interacting causes and feedback loops. The new oil surpluses flowed into an existing dollar-based system, but they were also deliberately recycled and reinvested.

1. Bretton Woods: The Order of the Convertible Dollar

The Bretton Woods conference, held in July 1944 with 44 countries
participating, created a system of fixed but adjustable exchange rates.
Participating currencies were pegged to the dollar, while the dollar
remained convertible into gold for foreign monetary authorities at the
official price of $35 an ounce. The International Monetary Fund and the
International Bank for Reconstruction and Development, the nucleus of
the future World Bank, also emerged from that compromise.¹

In the negotiations, the American approach associated with Harry
Dexter White largely prevailed over John Maynard Keynes’s more ambitious
plan. The U.S. advantage was structural: after the war, the United
States held a dominant share of the world’s gold reserves and possessed
unmatched productive capacity. The system worked as long as the rest of
the world trusted Washington’s ability to convert official dollar
holdings into gold.

2. The Contradiction Before 1973: Inflation, Offshore Dollars, and
   Gold

During the 1960s, the Bretton Woods crisis grew out of the
interaction of two trends. U.S. economic and monetary policy became more
inflationary just as the dollar was expected to remain credible as
gold’s monetary equivalent. At the same time, American investment,
lending, aid, and overseas spending generated a growing stock of dollar
claims held outside the United States. The issue therefore concerned not
merely banknotes, but the full range of dollar liabilities held by
foreign banks, corporations, and monetary authorities.²

2.1. Why U.S. Monetary Policy Became More Inflationary

U.S. inflation predated the end of Bretton Woods; it was not created
by the “Nixon Shock.” From the mid-1960s onward, Washington
simultaneously pursued full employment, Great Society programs, and
financing for the Vietnam War. Fiscal imbalances interacted with a
monetary policy that remained accommodative for too long and with the
then-influential belief that somewhat higher inflation could be
tolerated in exchange for lower unemployment. It would nevertheless be
too simple to reduce the Great Inflation to a single mechanism: wage and
price rigidities, inflation expectations, imperfect data, food and
energy supply shocks, and wage-and-price controls all helped, at
different times, to amplify or prolong it. The Federal Reserve’s
historical account dates the beginning of the Great Inflation to 1965
and ultimately traces it to policies that allowed excessive growth in
the money supply; the 1973 oil shock then added a major cost-push
component to an inflationary process already under way.³

The link to Bretton Woods is crucial. As long as official
convertibility remained in force, an overly expansionary policy could
produce external deficits, an accumulation of dollars in foreign
official hands, and demands for conversion into gold. Gold outflows from
U.S. reserves therefore imposed an external discipline: in principle,
they should have pushed the Federal Reserve toward higher interest rates
and tighter policy. After August 15, 1971, that particular constraint
disappeared. Inflation did not become inevitable, but foreign central
banks could no longer present dollars to the U.S. Treasury and demand
gold at the official price.

2.2. How the Stock of Dollars Held Abroad Grew

The phrase “dollars abroad” should not conjure up mainly physical
banknotes shipped across the Atlantic. In most cases, these were bank
claims, deposits, securities, and official reserves denominated in
dollars. When the U.S. government paid for troops, bases, supplies, or
foreign aid; when an American company invested in Europe; when a U.S.
bank lent to a nonresident; or when an American resident purchased a
foreign asset, the recipient normally acquired a dollar balance recorded
within the banking system. That balance could remain outside the United
States as a deposit or be transferred to the central bank of the country
concerned.

It is important to distinguish the trade balance from the overall
balance of payments. In the early 1960s, the United States could still
record a current-account surplus while running an overall payments
deficit: large private American investments in Europe, overseas military
expenditures, aid, and other capital flows sent more dollars abroad than
came back through those channels. The Federal Reserve explicitly notes
that after full convertibility was restored in 1958, the United States
initially continued to run current-account surpluses, while large U.S.
investments in Europe generated overall payments deficits and
intensified gold outflows.⁴

2.3. Eurodollars: Dollar-Based Bank Expansion Outside the United
States

The Eurodollar market developed on this foundation. A Eurodollar is
not a different currency; in the classic sense, it is a
dollar-denominated deposit held at a bank outside the United States.
London became the market’s principal center. The Bank for International
Settlements⁵ notes that dollar deposits had begun
to accumulate at banks outside the United States by the late 1950s and
that, precisely to track their expansion and potential monetary
consequences, the BIS began compiling international banking statistics
in the 1960s.

The market grew because offshore banks could avoid costs and
restrictions that applied to U.S. domestic intermediaries–deposit-rate
ceilings, reserve requirements, and other burdens–and could therefore
offer higher returns to depositors and competitive terms to borrowers.
In 1966, Regulation Q⁶ became especially restrictive in the
United States, and American banks themselves increasingly turned to
their London offices to raise dollars.

A London bank receiving a dollar deposit could use it to make a loan;
a payment made by the borrower could become another customer’s deposit
at another bank and support additional lending. A growing network of
dollar-denominated deposits and loans thus greatly expanded
international intermediation. This process should not, however, be
treated as a mechanical money multiplier directly controlled by the
Federal Reserve. Offshore banks expanded their balance sheets through
funding, lending, interbank markets, and regulatory arbitrage, subject
to liquidity, capital, and counterparty-risk constraints. They created
dollar claims and deposits, not Federal Reserve reserves. Final
settlement of dollar positions still depended on correspondent accounts
and, ultimately, on the U.S. monetary infrastructure; the Fed was the
settlement anchor, not the direct spigot for every Eurodollar loan.

Circuit in brief: U.S. spending, investment, or
lending sends dollars abroad → a foreign recipient acquires a dollar
claim → the dollars are deposited with a bank or central bank → the
funds are redeployed in the Eurodollar market → new dollar-denominated
loans and deposits are created. The circuit expands offshore credit, but
it does not mechanically create Federal Reserve reserves.

2.4. The Gold Constraint and de Gaulle’s Challenge

The result was the Triffin paradox:⁷ the
world needed dollars to finance trade and build reserves, but every
additional dollar held abroad increased potentially convertible
liabilities against a U.S. gold stock that was not growing at the same
pace. By 1961, according to the Federal Reserve’s account, dollar claims
had exceeded the official-price value of the U.S. gold stock. The more
successful the system became at supplying global liquidity, the more
fragile convertibility became.

The most explicit challenge came from Charles de Gaulle’s France. On
February 4, 1965, the French president denounced the dollar’s
“privilege” and called for a return to an impersonal gold basis for
international settlements. Paris acted on that position by
systematically converting a growing portion of its dollar holdings into
gold. Valéry Giscard d’Estaing’s memoirs even recount an unrealized idea
attributed to de Gaulle: sending the cruiser Colbert to New
York to speed up the withdrawal of gold corresponding to French dollar
holdings. The later popular image of a ship physically loaded with
banknotes and sent to the United States in exchange for bullion is vivid
but undocumented. The established historical fact is more consequential:
France was in fact exercising its right to convert dollars into gold at
$35 an ounce, draining U.S. reserves.⁸

On August 15, 1971, Richard Nixon closed the “gold window”: foreign
central banks could no longer exchange dollars for gold at the official
price. This was the crucial shift. It was not the moment when the dollar
became legal tender–it already was–but the moment when, in the
international monetary system, it lost its contractual gold anchor and
became fully fiat money, no longer convertible into a fixed quantity of
metal. The Smithsonian Agreement of December 1971 tried to preserve
fixed parities around a devalued dollar, but it did not last. The dollar
was devalued again in February 1973, and the major European currencies
floated against it the following month. The Gold Exchange Standard thus
gave way, de facto, to a dollar standard without gold convertibility:
the dollar remained the principal international unit of account, reserve
asset, and settlement currency without promising gold. Floating was not
an automatic consequence of fiat money, but of the collapse of fixed
parities and subsequent policy choices. The 1976 Jamaica agreements and
the Second Amendment to the IMF Articles of Agreement, effective in
1978, formalized countries’ freedom to choose their exchange-rate
arrangements and reduced gold’s official monetary role. Operationally,
Bretton Woods had ended months before the Yom Kippur War.⁹

3. The Bridge Between Monetary Crisis and Oil: 1971–1972

Here lies an often-overlooked transition. The monetary rupture
directly affected oil-producing countries because benchmark Gulf crude
prices were already denominated in dollars. Dollar devaluation therefore
reduced the international purchasing power of their oil revenues. On
January 20, 1972, under the Geneva Agreement, Gulf OPEC members obtained
an 8.49 percent increase in “posted prices” from the oil companies,
along with an exchange-rate adjustment mechanism. A contemporary CIA
document explicitly linked the demand to the suspension of dollar
convertibility on August 15, 1971, and the subsequent dollar
devaluation.¹⁰

This does not mean that the end of Bretton Woods “caused” the 1973
war. It does mean that by the time war broke out, relations between oil
producers and the Western monetary system had already become politicized
in part because dollar-denominated oil revenues had lost real purchasing
power. Oil pricing and the dollar had already intersected before Yom
Kippur.

4. Yom Kippur: From War to the “Oil Weapon”

On October 6, 1973, Egypt and Syria attacked Israel; the cease-fire
was consolidated by October 26. From the opening hours, Washington
regarded the risk of an oil embargo as very high and asked the CIA to
assess its potential impact.¹¹

On October 17, the Arab members of OAPEC decided on progressive
production cuts of at least 5 percent per month, tying them to Israeli
withdrawal from occupied territories and the Palestinian question. At
the same time, Gulf OPEC members unilaterally raised the price of crude
by 70 percent, from $3.01 to $5.12 a barrel; embargoes or threats of
embargo followed against the United States and other countries regarded
as supporters of Israel.¹²

By December 23, 1973, the average crude price charged by the major
exporters had risen to about $11 a barrel, nearly four times the level
at the beginning of October. The war was therefore the geopolitical
trigger for a shift in bargaining power already prepared by the rise of
OPEC, growing world demand, and the monetary deterioration of the
dollar.¹³

For Israel, the crisis also contained a strategic lesson that
extended beyond the battlefield. In October 1973, Arab producers used
the Arab-Israeli conflict as a political multiplier for oil leverage:
production cuts and embargo measures were explicitly tied to Israeli
withdrawal and the Palestinian question. From that point forward, Israel
had an additional interest in preventing one of its wars from becoming
the “booster” for another surge in oil prices and, with it, a wave of
global economic pressure capable of falling on its own Western allies.
This is a strategic interpretation of the consequences of 1973, not a
quotation from an Israeli doctrine formally stated in those terms.¹⁴

5. The Real Post-Bretton Woods Order: Petrodollars, Banks, and
   Debt

The shock transferred enormous resources from importing countries to
producers in a very short period. In 1974, the current-account surplus
of the major oil-exporting countries reached roughly $68 billion; the
corresponding deficits were concentrated among industrial countries and,
even more heavily, oil-importing developing economies.¹⁵

Those surpluses had to be reinvested, but their destination was not
solely the spontaneous outcome of markets. Some flowed through official
institutions: in 1974 the IMF created an “Oil Facility,” which lent $2.4
billion to 45 countries between 1974 and 1976. An increasing share of
recycling also passed through international banks, which took deposits
from exporting countries and converted them into loans, particularly to
emerging economies. At the same time, Washington deliberately
constructed a political and financial channel with Saudi Arabia. A June
5, 1974 memorandum explicitly linked oil, investment, and monetary
policy and proposed a confidential, privileged financial relationship.
On June 8, the U.S.-Saudi Arabian Joint Commission on Economic
Cooperation was established, alongside a commission on security
cooperation. In July, Treasury Secretary William Simon told Nixon that
he intended to seek a Saudi commitment to place funds in short- and
long-term U.S. securities. The GAO later described the Joint
Commission’s purposes as including stronger political ties through
economic cooperation and the recycling of petrodollars. Markets and
policy therefore worked together. One of the lines leading to the Latin
American debt crisis of the 1980s–together with the later rise in U.S.
interest rates–runs through this circuit.¹⁶

Petrodollar recycling therefore did not arise on empty ground. In
1973–74 it plugged into an infrastructure already built by the
Eurodollar market: banks accustomed to taking dollars outside the United
States, moving them across financial centers, and lending them to public
and private borrowers in other countries. The oil shock multiplied the
scale of the circuit. Importers needed more dollars to pay for crude;
producers accumulated huge dollar surpluses; and much of those surpluses
returned to the international banking system and Western financial
markets. The market, so to speak, supplied the plumbing; policy helped
channel and stabilize a decisive portion of the flows, especially in the
relationship with Riyadh. There is therefore no need to choose between
“spontaneous recycling” and “political recycling”: the first describes
the mechanism of intermediation, the second the strategic effort to
shape its direction, security, and outlets. The BIS explicitly
identifies petrodollar recycling as one of the historical uses of the
international banking statistics developed to track these markets.¹⁷

It is therefore correct to speak of “petrodollars” as a financial
flow; it is less accurate to imagine a new monetary system formally
equivalent to Bretton Woods, with oil simply replacing gold. Gulf crude
was already priced in dollars before 1973, and the available public
record does not establish a June 1974 treaty that newly imposed
exclusive dollar invoicing on all Saudi oil sales. What the sources do
document clearly is more robust: in 1974 Washington and Riyadh tied oil
policy, security, economic cooperation, and surplus reinvestment more
closely together while the United States explicitly sought to attract
Saudi capital into U.S. assets and securities. Oil did not become the
dollar’s new “backing.” Along with the depth of U.S. financial markets
and the Eurodollar circuit, however, it helped reinforce demand for
dollars and the currency’s central international role after the loss of
the gold anchor.¹⁸

5.1. The Soviet Union: Energy Rents, Military Priority, and a Missed
Opportunity

The shock also produced a beneficiary outside the Arab front: the
Soviet Union. Moscow was a major oil producer and exporter, and the rise
in world prices sharply increased the value of its sales for hard
currency. A CIA assessment estimated that Soviet oil earnings in 1974
almost doubled, reaching at least $2.5 billion. This hard currency was
not a marginal addition. Soviet dependence on Western agricultural
imports had already become clear before the shock: in 1972 Moscow
purchased roughly 25 million metric tons of grain and soybeans for
nearly $1.6 billion, and in 1972–73 it bought about 37 million metric
tons of grain from the West, roughly 25 million of them from the United
States. The CIA observed that without those imports, significant
sacrifices in consumption would have been required. Energy earnings
therefore did not create the Soviet agricultural deficit; that problem
came first. From 1974 onward, however, oil revenue made recurrent
purchases of Western grain, feed, and other food products–as well as
plants, pipe, machinery, and technology–far more sustainable. In this
sense, oil rents became an essential part of the mechanism by which the
Kremlin could ease food and industrial bottlenecks without correcting
their structural causes.

The point is not that every petrodollar was earmarked in an
accounting sense for the armed forces. The mechanism was more important
and more indirect, and it is here that the true Soviet bottleneck
appears. The idea of resolving a European war through an extremely rapid
offensive had roots in the postwar military posture and remained central
to Soviet planning. It would not, however, be documentarily sound to
turn that idea into a single, unchanging plan attributed to Stalin and
left intact through 1991. The record is strong enough without that
simplification. A 1968 CIA memorandum described a rapid advance across
West Germany to the English Channel; a 1971 estimate spoke of taking
Western Europe “within a few weeks”; and a 1977 analysis described
Soviet doctrine as envisioning a theater offensive of roughly two weeks,
intended to destroy NATO’s military potential quickly and overrun West
Germany, the Benelux countries, and Denmark. Later assessments also
exposed the limits of the concept: simultaneous major offensives on the
central and flank sectors would overload air transport, tactical
aviation, logistics, and command; even large simultaneous airborne
operations against the Danish and Turkish Straits were judged
unsustainable in the first week. The phrase “to the Atlantic in two
weeks” should therefore be used as an effective shorthand for the
extreme compression of operational timelines, not as a literal quotation
from a single order that remained unchanged for decades.

This is where the missed opportunity becomes visible. Higher oil
prices gave the Soviet Union a financial margin that could have
accelerated modernization of the productive system, improved
infrastructure and agriculture, raised the quantity and quality of
consumer goods, and, above all, addressed systemic rigidities through
deeper reforms. To a large extent, the opposite happened. Part of the
new hard-currency income was absorbed by indispensable imports–grain
first of all–that prevented or eased immediate shortages, while energy
rents made it possible to postpone the choice among consumption,
modernization, and military power. Gur Ofer¹⁹
argued that the energy crises of 1973 and 1979 produced temporary
economic benefits for the Soviet Union, helped obscure the economy’s
true condition, and delayed necessary reforms. The CIA, meanwhile,
observed that Soviet leaders did not behave as though cost were the
primary constraint on military decisions and that defense absorbed
exceptional shares of industrial output, machinery, scientific
capability, and managerial resources. The dissipation did not lie in
buying grain; those imports were necessary. It lay in using external
rents to make both the agricultural deficit and a military establishment
built for an extraordinarily demanding continental strategy
simultaneously bearable, thereby postponing the choice between power and
reform. Oil bought the system time, but not productivity; when the
energy and hard-currency margin narrowed, the bottleneck reappeared.²⁰

6. The Italian Repercussion

For Italy, the overlap of the monetary and energy crises was
particularly severe: a weak and floating lira, heavy dependence on
imported energy, already-high inflation, and a worsening external
balance. A Bank of Italy reconstruction notes that the trade deficit
rose from about 1.7 trillion lire in the second half of 1973 to roughly
4.0 trillion lire in the first half of 1974; between December and March,
consumer prices rose at an annualized rate of 26 percent. The oil crisis
did not create Italy’s vulnerabilities by itself, but it amplified them
violently.²¹

The strategic consequence was twofold. On the one hand, Europe
discovered how energy dependence could become diplomatic vulnerability.
On the other, managing deficits and new capital flows became an integral
part of Western economic security. The question was no longer simply
“how much does oil cost?” but who controls supply, in what currency
transactions are settled, where the proceeds are reinvested, and who
finances the resulting imbalances.

7. Essential Chronology

8. Overall Assessment

• Bretton Woods died from internal monetary contradictions, not from
  the 1973 Arab-Israeli war; what followed should nevertheless be
  understood as a system of interacting causes and feedback loops rather
  than a one-way causal chain.
• Dollar devaluation had already opened a direct dispute with oil
  producers in 1971–72 over the real purchasing power of their
  revenues.
• The Yom Kippur War gave Arab producers the political opportunity to
  turn oil into an instrument of strategic pressure and accelerated the
  redistribution of world income.
• Petrodollar recycling helped consolidate the dollar’s financial
  centrality after the loss of the gold anchor: the Eurodollar
  infrastructure supplied the market mechanism, while U.S.
  policy–especially in the relationship with Saudi Arabia–helped direct
  and stabilize a decisive share of surpluses toward dollar assets and
  U.S. securities. This did not amount to a new “oil-backed gold
  standard.”
• For Europe, and especially Italy, 1973 meant the overlap of three
  vulnerabilities: currency, energy, and the balance of payments. That
  overlap, more than any single event, marks the historical break.
• The events of 1973 showed Israel that a Middle Eastern war could be
  transformed by Arab producers into a global energy lever, multiplying
  the political and economic cost of conflict.
• Higher oil prices simultaneously strengthened the Soviet Union and
  supplied the hard currency needed to sustain agricultural and
  technological imports that compensated for structural inefficiencies.
  The bottleneck was precisely this: an economy forced to buy grain in the
  West continued to allocate exceptional resources to a military
  establishment designed for a rapid, continent-scale European campaign.
  Energy rents bought time, eased shortages, and postponed the choice
  between military power and civilian modernization; the oil dividend was
  therefore both a strategic advantage and a missed opportunity.
• The expansion of the stock of dollars outside the United States was
  primarily a phenomenon of bank balance sheets and international credit,
  not the physical circulation of banknotes. The Eurodollar market was the
  hinge between the Bretton Woods crisis and later petrodollar recycling.
  Offshore dollar credit creation should not, however, be confused with a
  mechanical multiplication of Federal Reserve reserves: Eurodollar
  balance sheets had their own dynamics while remaining anchored to the
  dollar settlement system.
• Closing the gold window did not “invent” U.S. inflation, which had
  been accelerating since the mid-1960s, nor did it make the dollar legal
  tender, a status it already possessed. It severed the official
  dollar-gold link and opened the transition from the Gold Exchange
  Standard to a de facto dollar standard based on fiat money; the collapse
  of fixed parities in March 1973 led to floating rates, later formalized
  within the IMF framework through the Jamaica reform and the 1978 Second
  Amendment.

APPENDIX A

Oil Revenue and Soviet Military Spending, 1973–1980

Hard-currency oil earnings compared with CIA “dollar cost”
estimates of Soviet military activity

The table compares, year by year from 1973 through 1980, Soviet
hard-currency earnings from oil exports with CIA estimates of the
“equivalent dollar cost” of Soviet military activity. Cells carrying
footnotes report figures drawn directly from declassified CIA documents.
Unfootnoted military-spending figures for 1973, 1977, and 1978 are
interpolated estimates between documented points because the relevant
CIA reports for those years were not located.

The CIA’s “dollar cost” estimates represent what Soviet forces and
programs would have cost if developed, procured, and operated in the
United States. They are not actual Soviet budgets and are not direct
ruble-to-dollar conversions. Oil earnings, by contrast, are actual
hard-currency receipts. Adding the two columns shows that oil revenue
amounted to roughly 4–4.5 percent of the cumulative dollar-cost value
attributed to the Soviet military effort over the period.

   coefficient to each offshore loan.
6. Regulation Q was a U.S. banking regulation introduced in
   the 1930s as part of the system created after the 1929 crash. In the
   context discussed here, it had two main effects: (1) it prohibited U.S.
   banks from paying interest on demand deposits, and (2) it capped the
   rates banks could offer on many time and savings deposits. Its original
   purpose was to curb aggressive competition for deposits and reduce
   practices thought to be destabilizing. As market interest rates rose
   above Regulation Q ceilings in the 1960s, investors often found it less
   attractive to leave dollars in U.S. banks, while London banks could
   offer higher rates.
7. The Triffin paradox, or Triffin dilemma, takes its name
   from Belgian-American economist Robert Triffin, who formulated it in the
   late 1950s. When a national currency also serves as the world’s
   principal reserve currency, as the dollar did under Bretton Woods: (1)
   the world needs dollars to finance trade, investment, and central-bank
   reserves; (2) supplying those dollars requires the United States to send
   them abroad through military spending, investment, loans, aid,
   purchases, and eventually external deficits; and (3) the more dollars
   accumulate abroad, the less credible the promise to convert them into
   gold becomes. Under Bretton Woods, Washington promised foreign central
   banks dollar-gold convertibility at $35 an ounce.

17. Bank for International Settlements, “Introduction to
    BIS statistics”: international banking statistics can be used to track
    the recycling of oil exporters’ petrodollars; see also BIS, “Seven
    decades of international banking,” on the preexisting offshore structure
    of dollar intermediation. https://t.ly/UDyr2 ; https://t.ly/NZ7JJ The
    existence of that banking infrastructure does not exclude later state
    action to channel part of the surpluses toward particular markets and
    financial assets.
18. To avoid a common misunderstanding: U.S. documentation
    from February 1972 shows that Gulf oil “posted prices” were already
    denominated in dollars before the 1973 shock; IMF literature uses
    “petrodollar recycling” to describe the subsequent reinvestment of
    exporters’ surpluses. FRUS, vol. XXXVI, doc. 110; IMF, “Recycling
    Petrodollars in the 1970s,” sources cited in notes 10 and 15. The
    distinction matters. FRUS documentation establishes that Gulf posted
    prices were already in dollars; the 1974 U.S. documents establish
    Washington’s effort to attract Saudi investment and build a special
    relationship around oil, finance, and security. The public primary
    sources consulted do not reveal a June 1974 treaty that newly
    established an exclusive obligation to invoice all Saudi oil in dollars.

    Petrodollars in the 1970s”; GAO, ID-79-7.

19. Gur Ofer (1934–2022) was a prominent Israeli economist,
    a professor at the Hebrew University of Jerusalem, and a specialist in
    the Soviet and Russian economies. Born in Jerusalem in 1934, he studied
    economics and history at Hebrew University and earned a Ph.D. in
    economics at Harvard. He joined the Hebrew University faculty in 1968
    and served as chair of its Economics Department in 1985–86. His main
    research fields included the Soviet economy, reform of planned
    economies, post-Soviet transition, and later Israeli health economics.
    Ofer was one of the leading Western economic Sovietologists and, after
    the collapse of the USSR, played a practical role in training a new
    generation of Russian economists. In 1992 he helped found Moscow’s New
    Economic School with Russian economist Valery Makarov and for years
    chaired its international academic board. The school explicitly sought
    to introduce Russia to economics training modeled on leading Western
    universities.

    Military Spending,” 1975: the cost of military programs is assessed
    partly in terms of civilian goods and services forgone, and the study
    emphasizes defense’s heavy absorption of industrial production,
    machinery, and technical resources. Gur Ofer, “Comment on Yegor Gaidar,”
    in Timothy Besley and Roberto Zagha, eds., Development Challenges in
    the 1990s, World Bank/Oxford University Press, 2005, pp. 72–73: the
    1973 and 1979 energy crises brought temporary economic benefits to the
    Soviet Union, masked the economy’s real condition, and delayed necessary
    reforms. https://t.ly/T-lsz ; https://t.ly/Xy0OC ; https://t.ly/4yeTt On
