A Provincial Perspective of Nonlinear Okun’s Law for Emerging Markets: The Case of South Africa

Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2020
A provincial analysis of Okun’s law in South Africa is provided in this article from 1996 to 2016. Empirically, we rely on the nonlinear autoregressive distributive lag (N-ARDL) model whilst the Corbae-Ouliaris filter is used to extract the ‘gap ...

Electronic structure of small fullerenes : evidence for the high stability of C32 [PDF]

, 1998
The electronic structure of small fullerenes determined experimentally by anion photoelectron spectroscopy is compared with calculations. A huge mass signal and a large gap of 1.3 eV comparable to the gap of C70 have been found for C32, indicating that ...

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

The Correlation Between CO2 Emissions and GDP in a Sustainable Development Framework Using Kuznets Environment Curve

Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2020
After 1990, the problem of finding econometric models to assess the influence of economic development on the environment becomes a global goal, a central element of regional, national and Community policies.

Inference on Common Trends in a Cointegrated Nonlinear SVAR

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We consider the problem of performing inference on the number of common stochastic trends when data is generated by a cointegrated CKSVAR (a two‐regime, piecewise affine SVAR; Mavroeidis, 2021), using a modified version of the Breitung (2002) multivariate variance ratio test that is robust to the presence of nonlinear cointegration (of a known
