Modeling Markov switching ARMA-GARCH neural networks models and an application to forecasting stock returns. [PDF]
The study has two aims. The first aim is to propose a family of nonlinear GARCH models that incorporate fractional integration and asymmetric power properties to MS‐GARCH processes. The second purpose of the study is to augment the MS‐GARCH type models with artificial neural networks to benefit from the universal approximation properties to achieve ...

Direct versus iterated multiperiod Value‐at‐Risk forecasts
Abstract Since the late nineties, the Basel Accords require financial institutions to measure their financial risk by reporting daily predictions of Value at Risk (VaR) based on 10‐day returns. However, a vast part of the related literature deals with VaR predictions based on one‐period returns.

Estimating the volatility of asset pricing factors
Abstract Models based on factors such as size or value are ubiquitous in asset pricing. Therefore, portfolio allocation and risk management require estimates of the volatility of these factors. While realized volatility has become a standard tool for liquid assets, this measure is difficult to obtain for asset pricing factors such as size and value ...

Do Scarce Precious Metals Equate to Safe Harbor Investments? The Case of Platinum and Palladium
This research establishes the predictability and safe harbor properties of two scarce precious metals, namely, platinum and palladium. Utilizing their spot prices, the study concludes intermediate memory in the return structures of both precious metals, which implies the instability of platinum and palladium returns’ persistency in the long run ...

Testing for long memory in ISE using Arfima-Figarch model and structural break test [PDF]
This study examines long memory in Istanbul Stock Exchange (ISE) by using the structural break test in variance and ARFIMA-FIGARCH model. Our findings indicate that long memory does not exist in the equity return; however, it exits in volatility ...

The mass and energy‐capital conservation equations are employed to study the time evolution of mass and price of nonrenewable energy resources, extracted and sold to the market, in case of no‐accumulation and no‐depletion, that is, when the resources are extracted and sold to the market at the same mass flow rate.
