    Abstract of associated article: In this paper we examine the effects of model misspecification (robustness or RB) on international consumption correlations in an otherwise standard small open economy model with endogenous capital accumulation. We show that in the presence of capital mobility in financial markets, RB lowers the international consumption correlations by generating heterogeneous responses of consumption to productivity shocks across countries facing different macroeconomic uncertainty. In addition, we show that RB can also improve the model's predictions in three other moments of consumption dynamics: the relative volatility of consumption to income, the persistence of consumption, and the correlation between consumption and output. After calibrating the RB parameter using the detection error probabilities, we show that the model can explain the observed international consumption correlations as well as the other consumption moments quantitatively. Finally, we show that the main conclusions of our benchmark model do not change in an extension in which the agent cannot observe the state perfectly due to finite information-processing capacity

    0 + 0 = 2: Changeover of Stability and Photopolymerization Kinetics for the Rotator Phase of Long-Chain Acrylate through the Ultra-Addition Effect in Binary Systems

    The stability and lowest existing temperature for the rotator phase of long-chain acrylate were improved remarkably simply through the ultra-addition effect of physical blending of two long-chain acrylates, which leads to a wider operation window and better rotator-state photopolymerization. Hexadecyl acrylate (HDA) and tetradecyl acrylate (TDA) were proved existing rotator phase like previously reported octadecyl acrylate (ODA). The binary rotator phase systems were constructed by mixing HDA or TDA with ODA and investigated in detail through thermal analysis, X-ray diffraction, and photopolymerization kinetics. The chain-reaction photopolymerization conversion of the binary system significantly increased to 60% from near 0 for pure acrylate, which realized “0 + 0 = 2”. The mechanism of such an ultra-addition effect was explained on the basis of X-ray diffraction data and calculation of the geometric model. The effect of difference in chain length between two components on this enhancement was studied, and a threshold value was found

    Octadecyl acrylate was proven to exist in rotator phases, and the mechanism of its chain-reaction photopolymerization was revealed. The polymorphic behavior of octadecyl acrylate was studied by differential scanning calorimeter (DSC) and X-ray diffraction, which concluded that octadecyl acrylate exhibits two rotator phases (<i>R</i><sub>II</sub> and <i>R</i><sub>I</sub>), one orthorhombic crystal phase (<i>C</i><sub>ort</sub>), and one triclinic crystal phase (<i>C</i><sub>tri</sub>) phase. The chain-reaction photopolymerization of four phases of octadecyl acrylate were studied by photo-DSC, and the theoretical possibilities of one-dimension chain propagation in <i>R</i><sub>II</sub>, <i>R</i><sub>I</sub>, and <i>C</i><sub>ort</sub> phases were analyzed by using the molecular dynamics simulation results. Combining the experimental and calculation results, the chain-reaction polymerization mechanism either intralayer or interlayer was discussed and disclosed. The question of whether the chain-reaction polymerization of octadecyl acrylate can occur in crystal was answered, and the reason was explained
