Abstract This article argues that the lockdown of Hubei province in China due to Coronavirus outbreak provides a natural experiment study importance China's role global value chains. Since started during Lunar New Year, Hubei's migrant workers who went home could not return workplaces other provinces, resulting massive labor supply shock. I feed shock through Ricardian model with intermediate g...

The U.S. shale revolution, using new technologies to extract crude oil, has led dynamics in the supply side of global oil market. We ask whether revolution dampened role geopolitical risk price volatility. extend a reduced form Structural Break Threshold Vector Autoregressive (SBT-VAR) model structural SBT-VAR and identify innovations by allowing conditional heteroskedasticity. Compared with co...

The current study investigates the impact of real oil price shocks on Eurozone banking sector from February 2009 to 2022, using Structural Vector Autoregressive method distinguish reaction between bank indices and three structural indicators in market shocks. include global demand, supply shock, specific Our findings show that responds positively toward an oil-specific demand shock (oil price) ...

One of the important requirements in projectiles is to design a power supply for fuse consumption. In this study, an optimum design for the power supply, which includes a Miniaturized Inertia Generator (MIG), was introduced. The main objective of this research was to optimize the dimensions of the MIG with the aim of increasing energy. To achieve this, the design of experiment (DOE) was carried...

Motivated by the effects of COVID-19 pandemic, we present a theory Keynesian supply shocks: shocks that reduce potential output in sector economy, but that, reducing demand other sectors, ultimately push aggregate activity below potential. A shock is more likely when elasticity substitution between sectors relatively low, intertemporal high, and markets are incomplete. Fiscal policy can display...

Abstract We construct text-based measures of the primary concerns listed firms associated with spread COVID-19 and other epidemic diseases. identify which perceive to lose or gain from a given textually decompose epidemic's effect on firm's demand supply. find that effects manifest as simultaneous shock supply, both shocks affecting firms’ market valuations in equal measure average. By contrast...

The supersonic flow of a reactive gas mixture with Mach reflection oblique shocks and pulsed energy supply at the stem is considered within framework Chapman–Jouguet theory. An approximate analytical model proposed that quickly determines shape size shock-wave structure as well parameters in various regions. As an example application model, “first barrel” highly overexpanded jet air-methane hig...
