In this paper we establish a general form of the Mass Transference Principle for systems of linear forms conjectured in [1]. We also present a number of applications to problems in Diophantine approximation. These include a general transference of Khintchine–Groshev type theorems into Hausdorff measure statements. These statements are applicable in both the homogeneous and inhomogeneous setting...

Using a new dataset of currency option prices, we study the evolution of investor confidence in 1992-1998 over the chance of individual currencies to converge to the Euro. Convergence risk, which may reflect uncertainty over policy commitment as well as exogenous fundamentals, induces a level of implied volatility in excess of actual volatility (volatility wedge). We show formally that confiden...

This study was conducted in 2016 aimed to investigate the relationship between empowering leadership, uncertainty avoidance, trust, and employee creativity with regard to interaction effects and mediating mechanism. The population consists of 205 employees from the Nomadic affairs of Fars Province. In accordance with the Cochran formula, the sample size of 134 was calculated that were participa...

Based on uncertainty management theory [Lind, E. A., & Van den Bos, K., (2002). When fairness works: Toward a general theory of uncertainty management. In Staw, B. M., & Kramer, R. M. (Eds.), Research in organizational behavior (Vol. 24, pp. 181–223). Greenwich, CT: JAI Press.], two studies tested whether a management style depicting situational uncertainty moderates the relationship between ab...

Uncertainty has an almost negligible impact on project value in the standard economic model. I show that a comprehensive evaluation of uncertainty and uncertainty attitude changes this picture fundamentally. The illustration of this result relies on the discount rate, which is the crucial determinant in balancing immediate costs against future benefits, and the single most important determinant...

Node cooperation during packet forwarding operations is critically important for fair resource utilization in Community Wireless Mesh Networks (CoWMNs). In a CoWMN, node cooperation is achieved by using fairness protocols specifically designed to detect and isolate malicious nodes, discourage unfair behavior, and encourage node participation in forwarding packets. In general, these protocols ca...

Paralleling regulatory developments, we devise value-at-risk and expected shortfall type risk measures for the potential losses arising from using misspecified models when pricing and hedging contingent claims. Essentially, losses from model risk correspond to losses realized on a perfectly hedged position. Model uncertainty is expressed by a set of pricing models, relative to which potential l...

This paper uses a new data set that better measures inflation uncertainty to investigate the effects of inflation and inflation uncertainty on economic growth. In the cross section of forty-four countries that the new data allows, inflation uncertainty has a significant negative impact on economic growth. Uncertainty performs better than inflation crisis as an explanatory variable of economic g...

This paper considers a hierarchical screened Gaussian model (HSGM) for Bayesian inference of normal models when an interval constraint in the mean parameter space needs to be incorporated in the modeling but when such a restriction is uncertain. An objective measure of the uncertainty, regarding the interval constraint, accounted for by using the HSGM is proposed for the Bayesian inference. For...
