This discussion paper led to a publication in <A href="http://www.tandfonline.com/doi/abs/10.1198/jbes.2011.10070">'Journal of Business & Economic Statistics'</A>, 29(4), 552-63.<P>We propose a new class of observation-driven time-varying parameter models for dynamic volatilities and correlations to handle time series from heavy-tailed distributions. The model adopts...</p></a>

This paper investigates whether the real exchange rate uncertainty depresses Thailand’s exports to the United States and Japan and thus causes the trade balances to deteriorate under the floating exchange rate regime. Monthly data from July 1997 to December 2007 are utilized. Industrial...

This paper examines the role of mechanical refrigeration in temporal and spatial price relationships for regional egg markets in the United States, 1880–1911. Notably, this period encompasses an era in which widespread adoption of mechanical refrigeration greatly impacted the ability to...

The Granger causality test is reduced, after co-integration, to the test of the fact that some coefficients of linear regressions are equal to zero or not. In this paper we will build multi-variate Bayes tests for the signification of the parameters of linear regression provided by the above...

Many questions have been raised as to whether financial accounting has become more conservative. The value relevance and qualitative characteristics of accounting information have become topics of particular relevance given the role they have assumed in influencing the value judgment of...

This paper has attempted to estimate the J-curve phenomenon for Azerbaijan using quarterly industry-level data over the period 2000-2009. A weighted average of the production indexes of Azerbaijan’s four major trading partners, which account for 70% of Azerbaijan’s total trade turnover, was...

This paper examines the presence of nonlinear mechanisms in the exchange rate pass-through (ERPT) to CPI inflation for 12 euro area (EA) countries. Using smooth transition models, we explore the existence of non-linearities with respect to three macroeconomic factors, namely inflation rate,...

This paper uses the cross-sectional variance of the betas from the CAPM model to study herd behavior towards market index in Romania. For time-varying beta determination, three different modeling techniques are employed: two bivariate GARCH models (DCC and FIDCC GARCH), two Kalman filter based...

The study provide an analysis of the macroeconomic issues surrounding the reforms needed to meet the country’s growth target, as well as to identify existing policy and structural constraints and macroeconomic policy reforms measures that would help to remove those constraints. The indicative...

An exploratory estimation of ARFIMA(p,d,q) models showed that the estimated d is sensitive to the short-term dynamics included. To address this issue, I run a series of Monte Carlo experiments and test the performance (i) of the AIC and the SIC in selecting p and q and (ii) of the AIC, the SIC...
