This study examines the relationship between public debt on both short and long-run economic growth, in a panel of selected Asian countries for the period of 1980–2012. We employ several econometrics methods: pooled mean group, mean group, dynamic fixed effects and also allow for common correlated effects. The impact of a change in public debt is also analysed using asymmetric panel ARDL method. Our results indicate that an increase in government debt is negatively associated with economic growth in both the short and long-run.

We examine whether the stock return performance of 620 Eurozone companies based on their environmental, social and governance (ESG) ratings both before and during the Covid‐19 pandemic on both a nominal and risk adjusted basis. We also look at how country level governance indicators interact with our samples of ESG_High and ESG_Low companies to affect both nominal and risk adjusted investment returns. We use both panel data and cross‐sectional regressions as well as the difference‐in‐differences approach to derive the empirical results. We generally find some evidence that highly rated ESG firms performed slightly worse than lower rated ESG both overall and during the pandemic. However, once we control for governance at the country level, we find that in high governance scoring countries ESG_High companies perform better than ESG_Low companies. Finally, when we examine the relative performance of EU companies compared to companies in economies less impacted by the Covid‐19 pandemic, namely South Korea and Australia, we find that during the pandemic, the South Korean and Australian companies performed much better than their counterparts in Europe.

A non parametrictest of popular modern exchange rate models under alternative expectation specifications is presented. It is found that there is little difference in the predictive success of the alternative exchange rate models, however, there are significant differences in the performance of a model depending upon the expectations mechanism specified. Our most important finding is that the flexible price monetary model, the portfolio balance model and a hybrid model under extrapolative and adaptive expectations mechanisms provide statistically significant information about the direction of exchange rate movements. By contrast, the same models when employing static, regressive and rational expectation mechanisms do not provideany satistically significant information.
