Most of the canonical macroeconomic models simulate liquidity anomalies by changing economic fundamentals or adding massive financial shock to firms’ collateral constraints, but a few facts somehow tell different story. Instead relying on exogenous shocks, we introduce uncertainty into an otherwise classical framework and try answer what worsens aggregate in absence simulations firm dynamics fi...

one of the most fundamental components of healthcare system on each country is blood supply chain management. this chain is comprised of two significant components including collecting donor’ bloods and supplying blood’s products. the main purpose of this paper is to concentrate on supplying blood products and present a novel constrained bi-objective mathematical model for a two-echelon blood s...

The electricity industry is a basic industry of the national economy. It has experienced several large-scale power shortages, hard power shortage and soft power shortage, which have brought a great threat to China’s sustainable economic development. To solve this problem better, it is necessary to make a quantitative assessment of the economic impacts of power shortage. The CGE model is commonl...

PURPOSE With the previous norepinephrine shortage, alternative agents were required to treat patients with septic shock. This retrospective study evaluated whether the shortage of norepinephrine had an adverse effect on patients admitted to the intensive care unit with a diagnosis of severe sepsis or septic shock.

The aging of the nursing workforce, and the global nature of this shortage, compound usual contributing factors. Given the far-reaching implications of the projected shortage, I explore key i...

background and objectives: a sudden jump in blood demand during natural disasters may have strong negative impact on the performance of blood supply chain. appropriate response to the emergency situations, requires predictive approach to determining the optimal allocation of blood supply chain resources for various disaster scenarios. the present study, thus, presents an optimization model aime...
