to respond because excess production goes into
stocks with the government’s effective purchase of
supplies at the loan rate. Thus, market demand faces
prices that are held higher than they would otherwise
be. This not only means that domestic market
demands see higher prices, such as higher market
prices for feed that increase production costs to
livestock producers, but that U.S. exports to
international markets are at higher prices, thereby
reducing U.S. competitiveness in global trade and
encouraging increases in foreign production.
In subsequent years, the government sells or
releases stocks when prices are higher, keeping
prices from rising further, but also extending market
impacts over a longer time period. Although this
imposes further distortions to the marketplace, effects
are in the opposite direction to those that occur in the
lower-price years when the government accumulates
stocks. As a result, government stock accumulation
in low price years and stock release in higher price
years may contribute to some reduction in multi-year
price variability. Also, while effects of price
supporting loan programs may extend over a longer
period of years, multi-year cumulative impacts on
total supply may be largely offsetting.
Marketing Loans
In contrast, program benefits under marketing
loans are provided through an income transfer rather
than through a price support. Per-unit revenues to
producers are supported but market prices are not.
Government budgetary costs are largely through
direct payments to farmers and costs of net loan
activity (including marketing loan gains), but there are
not significant governmental stockholding costs. In
contrast to price-supporting loans with costs reflecting
the full loan rate paid on part of the crop, marketing
loan costs reflect a portion of per-unit revenues (the
gap between the loan rate and the market price)
potentially paid on the full production of the crop.
As for price-supporting loans, production is
increased as farmers base planting decisions on net
returns that reflect program benefits. However, for
marketing loans, net returns reflect part of the
revenues coming from the marketplace and part from
the government in the form of the marketing loan
benefit (either a marketing loan gain or a loan
deficiency payment). Again, economic efficiency is
lowered because of the resulting misallocation of land
and other resources. With marketing loans, the
government does not remove production from the
marketplace through stock accumulation, so the
increase in production results in prices in the
marketplace being allowed to decline.
Impacts on equilibrium levels of quantities
demanded largely reflect market adjustments to the
higher production and lower prices. In domestic
markets, lower market prices for feeds, for example,
benefit livestock producers by reducing their
production costs. Foreign demand is influenced by
factors such as income, prices, and exchange rates.
Thus, the reduction in prices due to marketing loans’
impact on production pushes U.S. exports higher,
reflecting increased competitiveness in global trade.
In contrast to price-supporting loans, effects of
marketing loans occur mostly in years when
marketing loan benefits exist. While there may be
small dynamic carryover effects to subsequent years
through marginally higher private-sector stockholding,
there is no substantial release of government-held
stocks as can occur with price-supporting loans. As
a consequence, production impacts in low price years
are not offset in later periods. Thus, while marketing
loan distortions are more focussed in years of
marketing loan benefits, multi-year impacts on supply
are likely larger than for price-supporting loans.
Market prices are more variable than with a price-
supporting loan program, but per-unit revenues to
producers are increased.
Looking Towards the Future: Operating
Provisions Important
Other provisions are also important for the
operation of commodity loan programs, whether
implemented as price-supporting loans or as
marketing loans. For example, there is a wide range
of potential procedures for setting loan rates. Rates
could be pre-determined in agricultural legislation or
they could be allowed to vary across years, based on
formulas that use historical market prices, for
example. If set by formulas, they could be subject to
caps, as in the 1996 Farm Act. Additionally, the
