Impulse responses to a 10% shock to government consumption.
Impulse responses to a 10% shock to government consumption.</p
Computation and data.
The coronavirus pandemic has revived interest in the effects of fiscal policy. This paper studies the effects of government spending on default risk in emerging economies. We first build a general equilibrium small open economy model where government spending shocks influence external debt and sovereign bond spreads. We show that external debt piles up and sovereign bond spreads increase following a government spending shock. We then develop VAR evidence based on a panel of 18 countries. We find that in response to a 10% government spending increase, (1) the real effective exchange rate appreciates by 1.0% and the current account to GDP ratio deteriorates by 0.0025 on impact; (2) external debt increases by an average of 3.5% in the year following the shock; and (3) the EMBI Global spread rises by an average of 25 basis points within two years and peaks at 132 basis points 14 quarters after the shock, suggesting a higher sovereign default risk. The empirical results confirm the theoretical predictions from the general equilibrium model.</div

Dual Molecular Recognition Leading to a Protein–Polymer Conjugate and Further Self-Assembly
Supramolecular conjugation between
native protein concanavalin
A (ConA) and synthetic polymer PEG (polyethylene glycol) was achieved
by dual molecular recognition interactions via a linker, βCD-Man,
of which β-cyclodextrin (βCD) and α-mannopyranoside
(Man) recognized the adamantane (Ada) end of PEG and lectin ConA orthogonally.
Further self-assembly of the resultant supra-conjugates of ConA-PEG
was induced by the addition of αCD, which was selectively threaded
by PEG chains, leading to nanoparticles in dilute solution or hydrogel
at a higher concentration. The moduli of the obtained hydrogel were
three magnitudes higher than those of the control sample without ConA,
showing the dramatic cross-linking effect of ConA achieved by its
rather weak interaction with α-d-mannopyranoside
Cascade Molecule–Particle–Molecule Self-Assemblies for Fabricating Narrowly Size-Distributed Polymeric Superparticles with a Bicontinuous Nanostructure
Broader developments of nanoscience and nanotechnology
require
complexly but regularly structured nanoparticles whose fabrications
in turn pose a great challenge to nanoscience and nanotechnology.
In this communication, we report a new and robust method with a clear
mechanism for fabricating narrowly size-distributed superparticles
with a bicontinuous inner structure. The processes for the fabrication
include: molecular self-assembly of a triblock copolymer in its selective
solvent into the core–shell–corona micelles, the self-limited
aggregation of the micelles (particles)
into narrowly size-distributed superparticles constructed by the integrated
micelles, and the final molecular self-assembly confined within the
superparticles into cylinders that are crowded and interconnected
to form the bicontinuous nanostructure; the molecular self-assembly
into the micelles, the self-limited aggregation of the particles (i.e.,
the micelles), and the further molecular self-assembly within the
superparticles occurred in a cascade manner
