Business cycles are often regarded as aggregate phenomena. However, against the backdrop of rapid structural transformation in Chinese economy, they are also influenced by cyclical changes in various sectors and the evolution of the economic network structure. From the perspective of production...

This paper compares the renowned GARCH model with a novel one, the Generalized Autoregressive Score (GAS) model in terms of forecasting performance. Considering the gap in the literature, this study focuses on the Turkish stock and FX markets. The analysis covers 25 years (1999-2023), of which...

This paper examines the phenomenon of inflation inertia in Türkiye focusing on its persistence and the role of interconnected price-setting behaviors. Utilizing monthly data from 2004 to 2024, the study applies a novel augmented Phillips Curve framework, integrating a Time-Varying Parameter...

We introduce a new class of semiparametric dynamic autoregressive models for the Amihud illiquidity measure, which captures both the long-run trend in the illiquidity series with a nonparametric component and the short-run dynamics with an autoregressive component. We develop a GMM estimator...

We study the out-of-sample predictability of the real price of crude oil using forecast combinations constructed from several individual predictors. We find that forecasts of themonthly average price of oil are more accurate than the no-change forecast at horizons ranging from 1 to 24 months...

This article defines the Autoregressive Fractional Unit Root Integrated Moving Average (ARFURIMA) model for modelling ILM time series with fractional difference value in the interval of 1൏𝑑൏2. The performance of the ARFURIMA model is examined through a Monte Carlo simulation. Also, some...
