background and objectives: evaluating the performance of clinical units is critical for effective managementof health settings. certain assessment of clinical variables for performance analysis is not always possible,calling for use of uncertainty theory. this study aimed to develop and evaluate an integrated independentcomponent analysis-fuzzy-data envelopment analysis approach to accurate the...

This paper compares three reduced-form models of heterogeneity in survey inflation expectations. On the one hand, we specify two models of forecasting inflation based on limited information flows of the type developed in Mankiw and Reis [2002. Sticky information versus sticky prices: a proposal to replace the new Keynesian Phillips curve. Quarterly Journal of Economics 117(4), 1295–1328]. We pr...

Although a decrease in the rate of Chinese inflation happens, it will still be higher than was before global financial crisis. The international economy continue to deteriorate 2022 due geopolitical tensions and slowdown economic development experience small recession 2023. Studies show that EPU (economic policy uncertainty) index strongly explains large changes equity markets like S&P 500 ...

Noncommutative inflation is based upon the consideration of some effects of the space-time uncertainty principle motivated by ideas from string/M theory. The CMB anisotropies may carry a signature of this very early Universe correction from the spacetime uncertainty principle and can be used to place constraints on the parameters of the noncommutative inflation model. In this paper we analyze t...

To address the need for efficient and unbiased experimental testing of methods for decision under uncertainty, we devise an approach for probing weaknesses of these methods by running numerical experiments on readily available or easily obtainable databases of real life data. Since the approach uses real life data, it allows us to study the effect of modeling error on the performance of a metho...

inflation has always been an economic problem and different solutions have been proposed to control it. although it is said that “higher output lowers inflation rate” but it is true when other factors are constant. this study searches the answer to the following question: “what is the effect of inflation rate and output in a case that inflation rate and output growth has a volatility trend?” to...

Empirical evidence presented in this paper shows that the predictability of inflation at long horizons varies considerably across countries. Both simple theory and empirical evidence suggest that the crucial factor is the extent to which systematic monetary policy succeeds in stabilising the incipient unit root in inflation. The mechanism by which it does this appears however to be complicated ...
