Firm Entry under Financial Frictions [PDF]
Review of Development Economics, 2013 AbstractHow does a general‐equilibrium model behave when incorporating competitive firm entry that requires external finance? After conducting a steady‐state analysis, we reach three main results. First, the financial constraint has contractionary effects on both equity investment and the labor supply as they are inversely related to the marginal ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

FLUCTUATIONS AND MARKET FRICTION IN FINANCIAL TRADING [PDF]
International Journal of Modern Physics C, 2002 We study the relation between stock price changes and the difference in the volume of sell and buy orders. Using a soft spin model, we describe the price impact of order imbalances and find an analogy to the fluctuation–dissipation theorem in physical systems.

Advanced Materials, EarlyView.Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Monetary Policy and Reserve Requirement in a DSGE Model with Financial Frictions
Economia Aplicada, 2015 This paper modifies the DSGE model of Gertler & Karadi (2011), which includes financial frictions on the balance sheet of the financial intermediaries, to introduce reserve requirements that must be held at the Monetary Authority and a confidence shock ...

Advanced Materials, EarlyView.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Informality, Frictions and Monetary Policy [PDF]
How does informality in emerging economies affect the conduct of monetary policy? To answer this question we construct a two-sector, formal-informal new Keynesian closed-economy.
