EXPLANATION OF THE BASIC FORMULA PRICE PROVISIONS OF THE PROPOSED RULE
An important segment of milk marketing order reform involves replacing the current BFP. This working paper explains the background of the BFP issue, the options considered and the provisions of the proposed rule as related to the BFP issue.Marketing,

SOUTHERN FARMERS EXPOSURE TO INCOME RISK UNDER THE 1996 FARM BILL
Arguably, since the 1930s, what farmers produced has been markedly influenced by farm programs. The 1996 farm bill affects farmers in terms of what they produce and their level of risk exposure. This paper investigates the farm level impacts of the 1996 farm bill on the South. Focus group perceptions of risk sources, observed acreage changes, and the farm level impact of increased price risk are evaluated.Agricultural and Food Policy, Agricultural Finance,

Ground-based near-IR observations of the secondary eclipse of CoRoT-2b
We present the results of a ground-based search for the secondary eclipse of
the 3.3 Mjup transiting planet CoRoT-2b. We performed near infrared photometry
using the LIRIS instrument on the 4.2 m William Herschel Telescope, in the H
and K_s filters. We monitored the star around two expected secondary eclipses
in two nights under very good observing conditions. For the depth of the
secondary eclipse we find in H-band a 3 sigma upper limit of 0.17%, whereas we
detected a tentative eclipse with a depth of 0.16+-0.09% in the K_s-band. These
depths can be translated into brightness temperatures of T_H<2250 K and T_{K_s}
= 1890(+260-350) K, which indicate an inefficient re-distribution of the
incident stellar flux from the planet's dayside to its nightside. Our results
are in agreement with the CoRoT optical measurement (Alonso et al. 09) and with
Spitzer 4.5 and 8 micron results (Gillon et al. 09c).Comment: Astronomical Journal, accepte
Constraints on the Spin Evolution of Young Planetary-Mass Companions
Surveys of young star-forming regions have discovered a growing population of
planetary-mass (<13 M_Jup) companions around young stars. There is an ongoing
debate as to whether these companions formed like planets (that is, from the
circumstellar disk), or if they represent the low-mass tail of the star
formation process. In this study we utilize high-resolution spectroscopy to
measure rotation rates of three young (2-300 Myr) planetary-mass companions and
combine these measurements with published rotation rates for two additional
companions to provide a look at the spin distribution of these objects. We
compare this distribution to complementary rotation rate measurements for six
brown dwarfs with masses <20 M_Jup, and show that these distributions are
indistinguishable. This suggests that either that these two populations formed
via the same mechanism, or that processes regulating rotation rates are
independent of formation mechanism. We find that rotation rates for both
populations are well below their break-up velocities and do not evolve
significantly during the first few hundred million years after the end of
accretion. This suggests that rotation rates are set during late stages of
accretion, possibly by interactions with a circumplanetary disk. This result
has important implications for our understanding of the processes regulating
the angular momentum evolution of young planetary-mass objects, and of the
physics of gas accretion and disk coupling in the planetary-mass regime.Comment: 31 pages, 10 figures, published in Nature Astronomy,

A FARM-LEVEL LOOK AT THE FUTURE OF AMERICAN AGRICULTURE
Relatively low crop prices over the past two years, as well as regional weather adversity, has been the catalyst for the passage of "ad hoc" emergency relief. This paper examines the economic and financial status of 41 representative panel farms over the 1999-2002 period. When forecasting through the life of the 1996 Farm Bill, the representative crop farms are assessed by Texas A&M's Agricultural and Food Policy Center to be in the weakest condition observed over the last decade for liquidity and the related need to refinance.agricultural policy, farm profitability, liquidity, Agricultural and Food Policy, Agricultural Finance,
