This paper presents a novel dynamic factor model for non-stationary data. We begin by constructing a simple dynamic stochastic general equilibrium growth model and show that we can represent and estimate the model using a simple linear-Gaussian (Kalman) filter. Crucially, consistent estimation...

This paper derives series for capital utilisation, labour effort and total factor productivity (TFP) from a general equilibrium model with variable factor utilisation and labour adjustment costs. Impulse responses from the model show that firms initially respond to unanticipated shocks by...

Using Gretl, I apply ARMA, Vector ARMA, VAR, state-space model with a Kalman filter, transfer-function and intervention models, unit root tests, cointegration test, volatility models (ARCH, GARCH, ARCH-M, GARCH-M, Taylor-Schwert GARCH, GJR, TARCH, NARCH, APARCH, EGARCH) to analyze quarterly time...

We study a production-based present-value relation that implies that fluctuations in the marginal profit-to-marginal Q ratio (mq) are driven by variations in the expected growth of marginal profits (cash-flow channel), expected investment return changes (discount-rate channel), or both. We find...

This study estimated Tunisia's potential growth with a Cobb-Douglas production function using an unobservable component model within structural changes context for the period 1989-2023. It investigated the major shocks' effects on the potential growth and its components. In contrast with most...

We analyse micro-level data concerning four financial variables in Sveriges Riksbank's Prospera Survey to evaluate the accuracy of forecasts provided by professionals active in the Swedish fixed-income market. Our results indicate that for the SEK/EUR and SEK/USD exchange rates, and the...
