We use a structural vector autoregression model to identify and compare demand and supply shocks between euro area countries and central and eastern European countries (CEECs). The shocks and the shock adjustment dynamics of these countries are also compared to western European EU countries that have not yet adopted the euro. Focusing on the period 1993-2001, we find that there are still considerable differences in the shocks and in the adjustment process to shocks between the euro area and the CEECs. However, there are indications that the differences between several individual CEECs and the euro area have declined recently.

We use official intervention data for the period 1993-2000 that were released only recently by the BoJ and find that the interventions of the BoJ increased the volatility of the yen/U.S. dollar exchange rate. We find that that the interventions of the BoJ, in particular those interventions not reported in the financial press, were positively correlated with exchange rate volatility.

Using 30-minute tick returns, we examine the impact of changes in the number of COVID-19 news on eight different stock markets during the initial two months of the coronavirus crisis 2020. We do not find evidence that stock returns are sensitive to the changes in the number of COVID-19 news. However, there is strong evidence that changes in COVID-19 news increase stock market volatility in European markets. The findings also suggest that a substantial part of market uncertainty can be explained by changes in the number of COVID-19 news. Our results are also robust to changes in the time intervals.

The first group includes non-EMU EU countries, the second group EFTA countries and the third group central and eastern European countries which seek EU membership over the next years. Our results suggest that, so far, EMU enlargement towards central and eastern European countries would involve significantly higher costs than EMU enlargement towards countries of the other two groups.
