Answers to the first two research questions
| Research question | BRATISLAVA | BUDAPEST | PRAGUE | WARSAW |
|---|---|---|---|---|
| Which of the following economic areas’ sets of variables — i.e. the National, the V4, the EMU, or the USA — best explain fluctuations in the yield rates for the four office markets? | The V4 | The EMU | The National | The USA |
| Which variables representing the consecutive groups of factors — i.e. monetary influence, capital market factors, economic situation, or local market factors — have a dominant impact on the yield rates? | The monetary factor – changes in the inflation rate (DHICPV4) | Long-term impact: The capital market factor – interest of government bonds (B10E); Short-term impact: The monetary factor – changes in the inflation rate (DHICPE) | The monetary factor – changes in the inflation rate (DHICPC) | The capital market factor – changes in interest from government bonds (DB10UL1) |
