Forecasting with Panel Data : Estimation Uncertainty Versus Parameter Heterogeneity
Pesaran, M. Hashem; Pick, Andreas; Timmermann, Allan - 2022
We develop novel forecasting methods for panel data with heterogeneous parameters and examine them together with existing approaches. We conduct a systematic comparison of their predictive accuracy in settings with different cross-sectional (N) and time (T) dimensions and varying degrees of...

Variable Selection and Forecasting in High Dimensional Linear Regressions with Structural Breaks
Chudik, Alexander - 2020
This paper is concerned with problem of variable selection and forecasting in the presence of parameter instability. There are a number of approaches proposed for forecasting in the presence of breaks, including the use of rolling windows or exponential down-weighting. However, these studies...

Variable Selection in High Dimensional Linear Regressions with Parameter Instability
Chudik, Alexander; Pesaran, M. Hashem; Sharifvaghefi, Mahrad - 2023
variable as well as the correlation of the covariates in the active set are allowed to vary over time, without committing to … establish three main theorems on selection, estimation post selection, and in-sample fit. These theorems provide justification …

Persistence, Non-Linearities and Structural Breaks in European Stock Market Indices
Caporale, Guglielmo Maria - 2019
This paper examines persistence, structural breaks and non-linearities in the case of five European stock market indices, namely the FTSE100 (UK), DAX30 (Germany), CAC40 (France), IBEX35 (Spain) and FTSE MIB40 (Italy), using fractional integration methods. The empirical results provide no...

Cycles and Long-Range Behaviour in the European Stock Market
Caporale, Guglielmo Maria - 2019
This paper uses a modelling framework which includes two singularities (or poles) in the spectral density function, one corresponding to the long-run (zero) frequency and the other to the cyclical (non-zero) frequency. The adopted specification is very general, since it allows for fractional...

Long-Run Linkages between US Stock Prices and Cryptocurrencies : A Fractional Cointegration Analysis
Caporale, Guglielmo Maria; de Dios Mazariegos, José Javier - 2022
This paper applies fractional integration and cointegration methods to examine respectively the univariate properties of the four main cryptocurrencies in terms of market capitalization (BTC, ETH, USDT, BNB) and of four US stock market indices (S&P500, NASDAQ, Dow Jones and MSCI for emerging...

Hybrid historical simulation VaR and ES : performance in developed and emerging markets
Zikovic, Sasa; Filer, Randall - 2009
We introduce a new hybrid approach to joint estimation of Value at Risk (VaR) and Expected Shortfall (ES) for high … lower cost in capital reserves. In ES estimation the hybrid model yields the smallest error statistics surpassing even the …

Imputing Monthly Values for Quarterly Time Series. An Application Performed with Swiss Business Cycle Data
Abberger, Klaus; Graff, Michael; Müller, Oliver; … - 2023
This paper documents a comparative application of algorithms to deal with the problem of missing values in higher frequency data sets. We refer to Swiss business tendency survey (BTS) data which are conducted in both monthly and quarterly frequency, where an information sub-set is collected at...

Forecasting random walks under drift instability
Pesaran, Mohammad Hashem; Pick, Andreas - 2008
This paper considers forecast averaging when the same model is used but estimation is carried out over different … estimation windows. It develops theoretical results for random walks when their drift and/or volatility are subject to one or … more structural breaks. It is shown that compared to using forecasts based on a single estimation window, averaging over …
