We present a novel formula for Gaussian Berezin correlation functions. A formula well known in the literature expresses these quantities in terms of submatrices of the inverse matrix appearing in the Gaussian action. Our formula allows one to evaluate these integrals without calculating the inverse of the matrix. The derivation of the formula is obtained via a recently proposed method to calcul...

Why are some countries so much richer than others? Development Accounting is a first-pass attempt at organizing the answer around two proximate determinants: factors of production and efficiency. It answers the question “how much of the cross-country income variance can be attributed to differences in (physical and human) capital, and how much to differences in the efficiency with which capital...

Effective communication requires knowing the “right” amount of information to provide; what is necessary for a naïve learner to arrive at a target hypothesis may be superfluous and inefficient for a knowledgeable learner. The current study examines fourto seven-year-olds’ developing sensitivity to over-informative communication and their ability to decide how much information is appropriate dep...

The current study offers insights into how a pricing strategy called partitioned pricing and its transparency can influence auction success variables. In the online auction environment, auction sellers have to make several surcharge decisions such as whether or not to omit surcharge information from their auction listings or how much the surcharge should be, etc. We found that auctions that did...

Aspects of Frequency Control Ancillary Services (FCAS) in the Australian National Electricity Market (NEM) are discussed. Several aspects are identified as being relatively unique and beneficial for the integration of large quantities of variable renewables. These include fully dynamic setting of regulation reserves based upon real-time measurement of the time error, a sophisticated ‘causer pay...
