Rational Expectations and Output Supply: Evidence from the Sugar Cane and Coffee Industries in Jamaica
This paper investigates the rationality and price responsiveness of sugar cane and coffee farmers in Jamaica for the period 1960-1980. The output supplied by these farmers is modeled to incorporate anticipation by farmers of commodity board actions. The structure of constraints imposed by the rationality of these anticipated responses 1s derived and tested by means of a likelihood ratio test statistic. The results support the joint hypothesis of rationality and price responsiveness. Policy implications of the anticipated response function are also identifies

RACIAL DISCRIMINATION IN HIRE/PURCHASE LENDING IN APARTHEID SOUTH AFRICA
A partial-observability model finds evidence of racial discrimination by retailers of consumer durables in apartheid South Africa. In particular, black households are 13 percentage points more likely to demand a hire/purchase loan but not to have one supplied than are other households, all else equal.Consumer finance, disequilibrium models, racial discrimination, truncated and censored models, South Africa, Financial Economics,
Taking aim at Mer and Axl receptor tyrosine kinases as novel therapeutic targets in solid tumors
Axl and/or Mer expression correlates with poor prognosis in several cancers. Until recently, the specific role of these receptor tyrosine kinases (RTKs) in the development and progression of cancer remained unexplained. Studies demonstrating that Axl and Mer contribute to mechanisms of cell survival, migration, invasion, metastasis, and chemosensitivity justify further investigation of Axl and Mer as novel therapeutic targets in cancer
Seismic evidence for shallow gas-escape features associated with a retreating gas hydrate zone offshore west Svalbard
Active gas venting occurs on the uppermost continental slope off west Svalbard, close to and upslope from the present-day intersection of the base of methane hydrate stability (BMHS) with the seabed in about 400 m water depth in the inter-fan region between the Kongsfjorden and Isfjorden cross-shelf troughs. From an integrated analysis of high-resolution, two-dimensional, pre-stack migrated seismic reflection profiles and multibeam bathymetric data, we map out a bottom simulating reflector (BSR) in the inter-fan region and analyze the subsurface gas migration and accumulation. Gas seeps mostly occur in the zone from which the BMHS at the seabed has retreated over the recent past (1975â2008) as a consequence of a bottom water temperature rise of 1°C. The overall margin-parallel alignment of the gas seeps is not related to fault-controlled gas migration, as seismic evidence of faults is absent. There is no evidence for a BSR close to the gas flare region in the upper slope but numerous gas pockets exist directly below the predicted BMHS. While the contour following trend of the gas seeps could be a consequence of retreat of the landward limit of the BMHS and gas hydrate dissociation, the scattered distribution of seeps within the probable hydrate dissociation corridor and the occurrence of a cluster of seeps outside the predicted BMHS limit and near the shelf break indicate the role of lithological heterogeneity in focusing gas migration
