We analyze complexity of financial (and general economic) processes by comparing classical and quantum-like models for random-ness. Our analysis implies that it might be that a quantum-like prob-abilistic description is more natural for financial market than the classical one. A part of our analysis is devoted to study the possibility of application of the quantum probabilistic model to agents ...

financial concepts and terms in conventional and Islamic banking, the impact of religion and language, and other individual variables on preferences for financial services. Data from a university graduate and undergraduate business students (n = 667) from the United Arab Emirates was used to investigate the role of financial knowledge, religion, and language on self-reported attitudes and prefe...

The concept of Islamic or Shariah-compliant finance is based on core tenets of Islam concerning property rights, social and economic justice, wealth distribution, and governance. One of the key features of the system is prohibition of riba (interest) and gharar (ambiguous contracts or deals) (Kabir and Mahlkrecht 2011, 74; El-Gamal 2009, 58–60). There is consensus among scholars that the prohib...

Vallecular cyst is a rare cause of upper airway obstruction in infants and children and presentation like acute stridor with near fatal respiratory distress is extremely rare. It is one of the rare causes of difficult intubation, during which cyst aspiration can improve the access. Vallecular cyst is commonly managed using microlaryngoscope and specialized instruments. We hereby report a method...

This paper proposes a jackknife Lagrange multiplier (JLM) test for instrumental variable regression models, which is robust to (i) many instruments, where the number of instruments may increase proportionally with sample size, (ii) arbitrarily weak and (iii) heteroskedastic errors. In contrast Crudu, Mellace, Sándor (2021, Econometric Theory 37, 281–310) Mikusheva Sun Review Economic Studies 89...

We develop a new semiparametric Bayes instrumental variables estimation method. employ the form of regression function reduced-form equation and disturbances are modelled nonparametrically to achieve better preditive power endogenous variables, whereas we use parametric formulation in structural equation, which is interest inference. Our simulation studies show that under small sample size prop...
