The problem of detecting unit roots in univariate and multivariate time series data is treated as a problem of multiple decisions instead of a testing problem, as is otherwise common in the econometric and statistical literature. Four examples for such multiple decision designs are considered:...

Realized volatility computed from high-frequency data is an important measure for many applications in finance. However, its dynamics are not well understood to date. Recent notable advances that perform well include the heterogeneous autoregressive (HAR) model which is economically...

Systematic risk factors are very important for economies and their impact becomes significant especially in a crisis period. One of the systematic risk factors is exchange rate risk and exchange market pressure (EMP) is taken as an indicator of exchange rate risk. In this study, we have analysed...

We explore empirically the incidence of price discovery for black pepper in the spot market and the nearby and first distant futures markets with October 2001 to February 2003 daily data from Kerala, India. Modern time series methods of cointegration and directed acyclic graphs show that price...

This study attempts to examine the price discovery process and volatility spillovers in Gold futures and spot markets of National Commodity Derivatives Exchange (NCDEX) by employing Johansen’s Vector Error Correction Model (VECM) and the Bivariate ECM-EGARCH(1,1) model. The empirical result...

This study makes a cross sectional case in investigating the validity, or otherwise, of the finance-driven growth hypothesis in the ECOWAS countries using annual data from 1970 to 2008 for seven countries namely: Burkina Faso, Cote d’Ivoire, The Gambia, Ghana, Nigeria, Senegal and Togo. In...

The 'saving for a rainy day' hypothesis implies that households' saving decisions reflect that they can (rationally) predict future income declines. The empirical relevance of this hypothesis plays a key role in discussions of fiscal policy multipliers and it holds under the null that the...

This paper investigates the relationship between human capital and economic growth in Pakistan with time series data. Estimated with the Johansen (1991) approach, the aggregate production function rejects one version of the endogenous growth formulation. But the fitted model indicates that the...

Die derzeitigen Turbulenzen auf den Immobilienmärkten in Ländern wie den USA und Spanien verstellen den Blick auf die längerfristige Entwicklung der realen Immobilienpreise. Während sie in den vergangenen Jahren in vielen westlichen Industrieländern deutlich anzogen, stagnieren sie...

The paper considers a neo-classical model set in the cost function approach to estimate primary energy factor demands for the Italian economy, using a translog cost function specification. Cointegration theory is employed to estimate the long-run factor share model, and the general to specific...
