Normal Utilization as the Adjusting Variable in Neo-Kaleckian Growth Models: A Critique

As well-known, the canonical Neo-Kaleckian growth model fails to reconcile actual and normal rates of utilization in equilibrium. Some recent contributions revive an old proposal for solving this problem – making the normal rate of utilization an endogenous variable that converges to the actual utilization rate – justifying it with new, micro-founded premises. We argue that these new justifications for the convergence of normal to actual utilization do not stand closer scrutiny. First, the proposed microeconomic model relies on various restrictive assumptions, some of which are mutually inconsistent. Second, the derivation of the macroeconomic adjustment mechanism from the microeconomic analysis involves a logical leap, that can be justified only by a very arbitrary assumption with little economic justification. Finally, we discuss the way in which this mechanism has been incorporated into the Neo-Kaleckian growth model by proposers of this approach. We show that, even if one puts aside, for the sake of argument, the first two points, the existence of autonomous components of demand is sufficient to invalidate the resulting macroeconomic model

Broadband quadrature-squeezed vacuum and nonclassical photon number correlations from a nanophotonic device

We report the first demonstrations of both quadrature squeezed vacuum and photon number difference squeezing generated in an integrated nanophotonic device. Squeezed light is generated via strongly driven spontaneous four-wave mixing below threshold in silicon nitride microring resonators. The generated light is characterized with both homodyne detection and direct measurements of photon statistics using photon number-resolving transition edge sensors. We measure $1.0(1)$~dB of broadband quadrature squeezing (${\sim}4$~dB inferred on-chip) and $1.5(3)$~dB of photon number difference squeezing (${\sim}7$~dB inferred on-chip). Nearly-single temporal mode operation is achieved, with raw unheralded second-order correlations $g^{(2)}$ as high as $1.87(1)$ measured (${\sim}1.9$~when corrected for noise). Multi-photon events of over 10 photons are directly detected with rates exceeding any previous quantum optical demonstration using integrated nanophotonics. These results will have an enabling impact on scaling continuous variable quantum technology.Comment: Significant improvements and updates to photon number squeezing results and discussions, including results on single temporal mode operatio

Low-dimensional quite noisy bound entanglement with cryptographic key

We provide a class of bound entangled states that have positive distillable secure key rate. The smallest state of this kind is 4 \bigotimes 4. Our class is a generalization of the class presented in [1] (IEEE Trans. Inf. Theory 54, 2621 (2008); arXiv:quant-ph/0506203). It is much wider, containing, in particular, states from the boundary of PPT entangled states (all of the states in the class in [1] were of this kind) but also states inside the set of PPT entangled states, even, approaching the separable states. This generalization comes with a price: for the wider class a positive key rate requires, in general, apart from the one-way Devetak-Winter protocol (used in [1]) also the recurrence preprocessing and thus effectively is a two-way protocol. We also analyze the amount of noise that can be admixtured to the states of our class without losing key distillability property which may be crucial for experimental realization. The wider class contains key-distillable states with higher entropy (up to 3.524, as opposed to 2.564 for the class in [1]).Comment: 10 pages, final version for J. Phys. A: Math. Theo

Bioenergetics of the cave cricket, Hadenoecus subterraneus

1. 1. In late spring, cave crickets in Mammoth Cave National Park were investigated in order that their bioenergetics might be elucidated.2. 2. A predictive relation between crop-empty live weight and hind femur length independent of sex was found.3. 3. Long-term weight loss patterns were 1.55 and 1.19mg/hr for females and males, respectively, suggesting feeding intervals of 11.5 and 9.9 days.4. 4. Calorific assimilation efficiencies were found to be 80.4% for females and 82.5% for males.5. 5. The estimated maximal metabolic rates were half that expected for insects of similar mass.6. 6. The mixed waste calorific levels were found to be exceptionally low.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26417/1/0000504.pd

Water budgets of cave crickets, Hadenoecus subterraneus and camel crickets, Ceuthophilus stygius

1. 1. Studies of cave and camel crickets from cave entrances in Mammoth Cave National Park have produced estimates of total water budgets and component contributions to water balance.2. 2. Weight specific (mg/g crop-free live weight/hr) total water loss (3.200 vs 2.220) and water gained in food (2.393 vs 1.902) are greater in cave than in camel crickets, respectively.3. 3. Weight specific evaporative water loss in both humid, still air (2.269 vs 1.325) and dry, moving air (15.28 vs 9.85) is greater in cave than in camel crickets, respectively.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26939/1/0000505.pd

Minsky and the Subprime Mortgage Crisis: The Financial Instability Hypothesis in the Era of Financialization

The aim of this paper is to develop a structural explanation of the subprime mortgage crisis, grounded on the combination of two apparently incompatible financial theories: the financial instability hypothesis by Hyman P. Minsky and the theory of capital market inflation by Jan Toporowski. Our thesis is that, once the evolution of the financial market is taken into account, the financial Keynesianism of Minsky is still a valid framework to understand the events leading to the crisis
