Abstract
The upswing in euro area commercial real estate (CRE) markets in recent years has reflected, in part, a strong appetite from international investors, including US investment funds. Since 2013 transactions in euro area CRE markets have more than doubled, alongside a 20% increase in prices (15% in real terms) and a decline in average yields from 5.2% to 3.5%. In parallel, the share of transactions by foreign investors increased to 54% in 2018, from an average of 49% in 2013 when a particularly strong pick-up in transaction volumes started. Furthermore, the role of investment funds in foreign transactions increased to 63% in 2018 from 48% in 2013, with around 40% of these on average originating from the United States.

Abstract
Productivity performance in European countries has been a policy concern for some time. This paper shows that productivity can be enhanced by product market policies which, by increasing competition and efficiency, facilitate higher rates of firms’ entry and exit (i.e., firm churning). Drawing on annual country-sector data for the period 2000-2014 across the EU countries, we find that: (i) competition-enhancing regulation is associated with a higher rate of firm churning; (ii) business churning, in turn, appears to be positively related to higher total factor productivity at the sector level by facilitating the entry of new competitive firms and the exit of less productive ones. Overall, we conclude that stringent product market regulation can be indirectly associated, via its impact on business dynamism, with the somewhat weak productivity performance in a number of EU countries. Thus, our results point towards significant productivity gains that could follow from the introduction of further competition-enhancing measures in product markets.

Abstract
This study seeks to answer whether it is possible to design an early warning system framework that can signal the risk of fiscal stress in the near future, and what shape such a system should take. To do so, multiple models based on econometric logit and the random forest models are designed and compared. Using a dataset of 20 annual frequency variables pertaining to 43 advanced and emerging countries during 1992-2018, the results confirm the possibility of obtaining an effective model, which correctly predicts 70-80% of fiscal stress events and tranquil periods. The random forest-based early warning model outperforms logit models. While the random forest model is commonly understood to provide lower interpretability than logit models do, this study employs tools that can be used to provide useful information for understanding what is behind the black-box. These tools can provide information on the most important explanatory variables and on the shape of the relationship between these variables and the outcome classification. Thus, the study contributes to the discussion on the usefulness of machine learning methods in economics.
