The financial crisis and U.S. cross-border financial flows

The financial crisis that began in the summer of 2007 caused notable changes in the composition of U.S. cross-border financial flows, especially in the fall of 2008, when the crisis intensified. This article documents three major channels through which financial flows and associated portfolio positions were affected: (1) “flight to safety” shifts away from riskier securities and toward investments in safe and liquid markets, particularly U.S. Treasury securities; (2) unusual flows through the banking system resulting from a shortage of dollar liquidity abroad and a breakdown in interbank markets; and (3) a pullback from cross-border positions during the crisis.Financial crises ; Government securities

SOURCES OF PRODUCTIVITY GROWTH DURING THE TRANSITION TO ALTERNATIVE CROPPING SYSTEMS

Traditional measures of productivity growth may not fully account for all sources of growth during the transition from conventional to alternative cropping systems. This paper treats soil quality as part of the production process and incorporates it directly into rotational measures of productivity growth. An application to data from an experimental cropping system in Pennsylvania suggests that both experimental learning and soil-quality improvements were important sources of growth during the system's transition.Productivity Analysis,

Transplantation of Fetal CNS Tissue Into the Peripheral Nervous System: A Model to Study Aberrant Changes in the Neuronal Cytoskeleton

Defined regions (septum, substantia nigra) of the embryonic central nervous system (CNS) were transplanted into the sciatic nerves of young adult rats. Immunocytochemical techniques were used to examine the expression of neurotransmitter related enzymes and neuronal cytoskeletal proteins in the grafts
