This paper reinvestigates the energy consumption-GDP growth nexus in a panel error correction model using data on 20 net energy importers and exporters from 1971 to 2002. Among the energy exporters, there was bidirectional causality between economic growth and energy consumption in the developed...

We checked against the law of one price between urban and rural consumer price indices of goods and services in Nigeria, using data that span January 1995 to April 2024. By first testing for persistence in price indices, we found a similar pattern of persistence that is non-mean reverting in all...

We propose a portfolio construction method that accounts for the regime-dependent behavior of stocks, thereby impacting their expected returns. Using a hidden Markov model (HMM) and a regime-weighted least-squares approach, we estimate forward-looking regime-conditional factors. These factors...

This paper makes a significant contribution to the literature on the policy trilemma by evaluating potential policy combinations that are relevant for the BRICS grouping within the context of the Impossible Trinity. Additionally, the paper introduces a new modeling approach for assessing the...

This paper uses a tax revenues reallocation scheme as the payment vehicle in a choice experiment to value marine restoration in the Black Sea. Two reallocation treatments are administered; one proposing to reduce current public expenditures on renewable energy projects and the other, the training...

Several semiparametric estimators recently developed in the econometrics literature are based on the rank correlation between the dependent and explanatory variables. Examples include the maximum rank correlation estimator (MRC) of Han [1987], the monotone rank estimator (MR) of Cavanagh and...

We study the distributions of the LASSO, SCAD, and thresholding estimators, in finite samples and in the large-sample limit. The asymptotic distributions are derived for both the case where the estimators are tuned to perform consistent model selection and for the case where the estimators are...

This paper develops a wavelet (spectral) approach to test the presence of a unit root in a stochastic process. The wavelet approach is appealing, since it is based directly on the different behavior of the spectra of a unit root process and that of a short memory stationary process. By...

ABSTRACT: In a recent paper, Dominique (2009) argues that for a Walrasian economy with m consumers and n goods, the equilibrium set of prices becomes a fractal attractor due to continuous destructions and creations of excess demands. The paper also posits that the Hausdorff dimension of the...

Traditionally an old concern among economists has referred to the effects that specific financial systems may have on economic performance. Here we investigate the “stylised facts” among financial systems and banking crises by using individual and principal-components indicators and sets of...
