The Feldstein Horioka Puzzle by groups of OECD members: the panel approach.

This paper investigates investment savings relationships in 26 OECD countries and how these relationships change when countries in the considered panel vary. Therefore panel estimations using annual data for the period 1970-2008 are made for different groups of developed countries, such as the OECD, EU15, NAFTA and G7. Additionally, this paper examines changes in investment saving relationships in groups of developed countries taking into account the presence of structural shifts in countries where they exist. Recent panel techniques are employed in this study to examine investment savings relationships and to estimate saving retention coefficients. The empirical findings reveal that the Feldstein-Horioka puzzle exists only in the panel of G7 countries where the saving-retention coefficient is estimated at the level 0.754 and 0.864 for the full sample of G7 countries and for stable countries, respectively. The estimated saving-retention coefficient for the G7 group of unstable appear at the 0.482 level, indicating a higher level of capital mobility in unstable countries compared to stable ones. This conclusion is supported by estimations for OECD and EU15 countries.Feldstein-Horioka puzzle, capital mobility, structural breaks, panel estimations, OECD.

Determinants of current account in the EU: the relation between internal and external balances in the new members

This paper considers the major determinants of the current account in the new members of the EU. It examines the long-run and short-run impact of real exchange rate, investment, private and public savings on current account. The bounds testing autoregressive distributed lag (ARDL) approach to cointegration is used and the results indicate that twin deficit exists; in another words, government budget deficit shocks have led to deficit in current accounts in Czech Republic, Latvia, Lithuania, Slovenia and Slovakia for the considered period. At the same time, empirical evidence was found that private savings, investment and real exchange rate are key variables as well, causing changes in the current account in the long-run as well as in the short-run. Finally, stability tests were applied to the model indicating no evidence of any structural instability in the model of these countries

Determinants of the Current Account in the Eu and PIIGS

This paper investigates the relationship between current account balance and national savings, investment, budget deficit, and real exchange rate. These determinants of the current account are studied empirically by applying the Generalized Method of Moments for a sample of 24 European countries. The sample data are divided into three different groups, PIIGS, EU-PIIGS, and EU in order to study the group-specific estimations. The main result of the paper is that the determinants of our model are capable of accurately explaining past movements in current accounts for all selected groups. Additionally, current account determinants in the economically weak members, PIIGS, behave slightly differently from the rest of the EU

Current trends in cannulation and neuroprotection during surgery of the aortic arch in Europe†‡

OBJECTIVES To conduct a survey across European cardiac centres to evaluate the methods used for cerebral protection during aortic surgery involving the aortic arch. METHODS All European centres were contacted and surgeons were requested to fill out a short, comprehensive questionnaire on an internet-based platform. One-third of more than 400 contacted centres completed the survey correctly. RESULTS The most preferred site for arterial cannulation is the subclavian-axillary, both in acute and chronic presentation. The femoral artery is still frequently used in the acute condition, while the ascending aorta is a frequent second choice in the case of chronic presentation. Bilateral antegrade brain perfusion is chosen by the majority of centres (2/3 of cases), while retrograde perfusion or circulatory arrest is very seldom used and almost exclusively in acute clinical presentation. The same pumping system of the cardio pulmonary bypass is most of the time used for selective cerebral perfusion, and the perfusate temperature is usually maintained between 22 and 26°C. One-third of the centres use lower temperatures. Perfusate flow and pressure are fairly consistent among centres in the range of 10-15 ml/kg and 60 mmHg, respectively. In 60% of cases, barbiturates are added for cerebral protection, while visceral perfusion still receives little attention. Regarding cerebral monitoring, there is a general tendency to use near-infrared spectroscopy associated with bilateral radial pressure measurement. CONCLUSIONS These data represent a snapshot of the strategies used for cerebral protection during major aortic surgery in current practice, and may serve as a reference for standardization and refinement of different approache

Capital mobility in Latin American and Caribbean countries: New evidence from dynamic common correlated effects panel data modeling

This study investigates the degree of capital mobility in a panel of 16 Latin American and 4 Caribbean countries during 1960 to 2017 against the backdrop of the Feldstein-Horioka hypothesis by applying recent panel data techniques. This is the first study on capital mobility in Latin American and Caribbean countries to employ the recently developed panel data procedure of the dynamic common correlated effects modeling technique of Chudik and Pesaran (J Econ 188:393-420, 2015) and the error-correction testing of Gengenbach, Urbain, and Westerlund (Panel error correction testing with global stochastic trends, 2008, J Appl Econ 31:982-1004, 2016). These approaches address the serious panel data econometric issues of cross-section dependence, slope heterogeneity, nonstationarity, and endogeneity in a multifactor error-structure framework. The empirical findings of this study reveal a low average (mean) savings-retention coefficient for the panel as a whole and for most individual countries, as well as indicating a cointegration relationship between saving and investment ratios. The results indicate that there is a relatively high degree of capital mobility in the Latin American and Caribbean countries in the short run, while the long-run solvency condition is maintained, which is due to reduced frictions in goods and services markets causing increase competition. Increased capital mobility in these countries can promote economic growth and hasten the process of globalization by creating a conducive economic environment for FDI in these countries
