The effective federal funds rate is determined in a competitive interbank market, while the target federal funds rate represents a policy variable. This paper proposes a theory of the determination of the effective funds rate. According to the main result, the latter is a Lagrange multiplier that vanishes if excess reserves emerge. This is exactly what happened in the United States in September...

A mutant of the NAD-malic enzyme-type C(4) plant, Amaranthus edulis, which lacks phosphoenolpyruvate carboxylase (PEPC) in the mesophyll cells was studied. Analysis of CO(2) response curves of photosynthesis of the mutant, which has normal Kranz anatomy but lacks a functional C(4) cycle, provided a direct means of determining the liquid phase-diffusive resistance of atmospheric CO(2) to sites o...

Reverse transcription quantitative real-time polymerase chain reaction (qRT-PCR) is a powerful analytical technique for the measurement of gene expression, which depends on the stability of the reference gene used for data normalization. Suaeda aralocaspica, an annual halophyte with heteromorphic seeds and possessing C4 photosynthesis pathway without Kranz anatomy, is an ideal plant species to ...

Photorespiration rates in tissue cultures of a C(4) plant, Portulaca oleracea, were compared to those in tissue cultures of a C(3) plant, Streptanthus tortuosus. The C(4) plant tissue cultures have one-half to one-third the photorespiration rate of the C(3) plant tissue cultures and respond to varying O(2) concentrations in a manner typical of C(4) plants. The results suggest that the lack of d...

In Brodeur, Cook, and Heyes (2020) we present evidence that instrumental variable (and to a lesser extent difference-in-difference) articles are more p-hacked than randomized controlled trial regression discontinuity design articles. We also find no (i) published in the top five journals different; (ii) “revise resubmit” process mitigates problem; (iii) things improving through time. Kranz Pütz...

Background: Understanding some part of the human body such as serous membrane, peritoneal cavity, lesser sac and proper mesentery is difficult for medical students. The objective of this study was to determine the effect of animal dissection on improving medical student knowledge and view related viscera and serous membrane anatomy. Methods: In YUMS in 2011, sixty eight medical students were ra...
