In this study, 3 models of Time-Varying Parameters (TVP), Dynamic Model Selecting (DMS) and Dynamic Model Averaging (DMA) and their comparison via the Ordinary Least Squares (OLS) method in MATLAB in the time period 2003-2013 (monthly) are discussed. In the present study the variables of unofficial exchange rate changes, interest rate changes and inflation oil price forecast returns for stocks ...

This paper investigates the modelling of style returns in the US and the returns to style “tilts” based on forecasts of enhanced future style returns. We use hidden Markov model to build our forecasts. Our finding that style returns are less forecastible in more recent years is consistent with the hypothesis that style returns are the result of anomalies rather than risk premia. The erosion of ...

Volatility in stock markets has been extensively studied in the applied finance literature. In this paper, Artificial Neural Network models based on various back propagation algorithms have been constructed to predict volatility in the Indian stock market through volatility of NIFTY returns and volatility of gold returns. This model considers India VIX, CBOE VIX, volatility of crude oil returns...

The study uses a novel approach to test for the persistence of green asset returns, fossil fuel and climate policy uncertainty. We find evidence in series when asymmetries are considered our test. returns uncertainty have no effect on sustainable returns. Policies around should be long term.

the measurement of rts amounts measures a relationship between inputs and outputs in a production structure. there are many different ways to calculate rts in primal or dual space. but in more realistic cases, governments usually intervene on dmu’s behavior as regulatory agency, this clearly represent a set of limitations and restrictions on behaviors of dmus, so very few decisions in dmus are ...

in this article, the effectiveness of eight different technical indexes including simple moving average, weighted moving average, exponential moving average, relative strength, commodity channel, stochastic, money flow and demand are examined by comparison between indexes returns with buy and hold returns. the results shows the return of buy and hold strategy is more than technical indexes in t...
