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...

Economic policy interventions of a scale as effected in eastern Germany can be expected to have a significant impact on the economy, which may be in accordance with the objectives of the policy measures or manifest itself in distortions of several kinds. This paper analyzes the structural...

Combining micro and macro data, we construct demand-side shocks, which we take to be exogenous for individual firms. We estimate a reduced-form model to describe how firms adjust their production, employment, capital stock, and inventories in response to such shocks. Then, we chose the...

How do firms adjust their output, inventories, employment and capital in response to demandsideshocks? To understand this, we estimate a reduced-form model using firm-level panel dataand we construct a theoretical model that can match the estimated impulse-response functions.A combination of...

Capital reallocation between firms is procyclical and leads to variations in measured aggregate productivity. In this paper, we ask how much of the cyclical variation in measured productivity is the consequence of capital reallocation. We build a heterogeneous-firm model to study the effects of...

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...

Theoretical models point at various channels of the impact of inflation on corporate investment. This article attempts to answer the question what the direction and strength of this possible impact is, examining the relationship between corporate investment and inflation on the sample of 21 OECD...

Since the recovery from the great financial crisis in 2010, global real trade flows grew much slower than pre-crisis, in both absolute terms (growth rates) and relative terms (relative to GDP, from 2:1 in the great 1990’s to 1:1 since 2012) A debate has arisen as to whether this global trade...
