The quality of public finances and economic growth
Improving the quality of public finances (QPF) has become a new focus for European policy makers. This focus is largely a response to preparing the European economies for the dual challenge of ageing populations and increased exposure to global competition. At the EU level, the Stability and Growth Pact and the Lisbon Strategy for Growth and Jobs provide, in principle, the appropriate tools for fostering a greater role of QPF in fiscal surveillance but this has not yet fully materialised in practice. This is partly because a broad-based conceptual framework on what makes up QPF has been missing. This paper attempts to close this gap by developing a multi-dimensional approach on QPF. Moreover, it reviews how EU Member States fare in each dimension and summarises empirical findings on the links between QPF and growth, including through a growth-accounting approach using discriminant analysis.Public finances, fiscal policy, public spending, fiscal governance, expenditure efficiency, revenue systems, growth accounting, Barrios, Schaechter
Gauging by numbers: A first attempt to measure the quality of public finances in the EU
Ensuring high quality of public finances (QPF) with a view to supporting long-term economic growth has gained new urgency as the room for fiscal manoeuvre has shrunk in light of the current crisis. To more systematically analyse QPF and compare developments across countries and over time, a greater focus on identifying and developing comparable QPF indicators is needed. This paper provides a first attempt in this respect. Based on the view that QPF is a multi-dimensional concept, it creates composite indicators for twelve areas of public finances that are linked to long-term economic growth. While the proposed alternative calculation methods yield relatively robust results and findings are in line with conventional wisdom, due to data problems the composite indicators should only be seen as a useful starting point for identifying a country's main strengths and weaknesses in QPF. This would need to be complemented by qualitative analysis that also accounts for country and other specificities.

Efficacy of motor imagery in post-stroke rehabilitation: a systematic review
BACKGROUND: Evaluation of how Motor Imagery and conventional therapy (physiotherapy or occupational therapy) compare to conventional therapy only in their effects on clinically relevant outcomes during rehabilitation of persons with stroke. DESIGN: Systematic review of the literature METHODS: We conducted an electronic database search in seven databases in August 2005 and also hand-searched the bibliographies of studies that we selected for the review.Two reviewers independently screened and selected all randomized controlled trials that compare the effects of conventional therapy plus Motor Imagery to those of only conventional therapy on stroke patients.The outcome measurements were: Fugl-Meyer Stroke Assessment upper extremity score (66 points) and Action Research Arm Test upper extremity score (57 points).Due to the high variability in the outcomes, we could not pool the data statistically. RESULTS: We identified four randomized controlled trials from Asia and North America. The quality of the included studies was poor to moderate. Two different Motor imagery techniques were used (three studies used audiotapes and one study had occupational therapists apply the intervention). Two studies found significant effects of Motor Imagery in the Fugl-Meyer Stroke Assessment: Differences between groups amounted to 11.0 (1.0 to 21.0) and 3.2 (-4 to 10.3) respectively and in the Action Research Arm Test 6.1 (-6.2 to 18.4) and 15.8 (0.5 to 31.0) respectively. One study did not find a significant effect in the Fugl-Meyer Stroke Assessment and Color trail Test (p = 0.28) but in the task-related outcomes (p > 0.001). CONCLUSION: Current evidence suggests that Motor imagery provides additional benefits to conventional physiotherapy or occupational therapy. However, larger and methodologically sounder studies should be conducted to assess the benefits of Motor imagery
Increasing upper limb training intensity in chronic stroke using embodied virtual reality: a pilot study.
Technology-mediated neurorehabilitation is suggested to enhance training intensity and therefore functional gains. Here, we used a novel virtual reality (VR) system for task-specific upper extremity training after stroke. The system offers interactive exercises integrating motor priming techniques and embodied visuomotor feedback. In this pilot study, we examined (i) rehabilitation dose and training intensity, (ii) functional improvements, and (iii) safety and tolerance when exposed to intensive VR rehabilitation.
Ten outpatient stroke survivors with chronic (>6 months) upper extremity paresis participated in a ten-session VR-based upper limb rehabilitation program (2 sessions/week).
All participants completed all sessions of the treatment. In total, they received a median of 403 min of upper limb therapy, with 290 min of effective training. Within that time, participants performed a median of 4713 goal-directed movements. Importantly, training intensity increased progressively across sessions from 13.2 to 17.3 movements per minute. Clinical measures show that despite being in the chronic phase, where recovery potential is thought to be limited, participants showed a median improvement rate of 5.3% in motor function (Fugl-Meyer Assessment for Upper Extremity; FMA-UE) post intervention compared to baseline, and of 15.4% at one-month follow-up. For three of them, this improvement was clinically significant. A significant improvement in shoulder active range of motion (AROM) was also observed at follow-up. Participants reported very low levels of pain, stress and fatigue following each session of training, indicating that the intensive VR intervention was well tolerated. No severe adverse events were reported. All participants expressed their interest in continuing the intervention at the hospital or even at home, suggesting high levels of adherence and motivation for the provided intervention.
This pilot study showed how a dedicated VR system could deliver high rehabilitation doses and, importantly, intensive training in chronic stroke survivors. FMA-UE and AROM results suggest that task-specific VR training may be beneficial for further functional recovery both in the chronic stage of stroke. Longitudinal studies with higher doses and sample sizes are required to confirm the therapy effectiveness.
This trial was retrospectively registered at ClinicalTrials.gov database (registration number NCT03094650 ) on 14 March 2017
Increasing upper limb training intensity in chronic stroke using embodied virtual reality: a pilot study
Implementation of Monetary Policy and the Central Bank's Balance Sheet
This paper discusses how the choice of central banks'' operating targets influences the use of their monetary policy instruments and how the latter affect the central bank''s balance sheet. This is of particular interest, since the monetary conditionality in IMF-supported programs has traditionally been linked to central bank balance sheet items. Quantity targeting tends to be practiced today mostly in countries in which money markets are not yet well-developed or a monetary aggregate is used as the intermediate target. Most other central banks prefer to target a short-term interest rate, which results in day-to-day changes in balance sheet items becoming endogenous.Conditionality;central bank, monetary policy, monetary base, inflation, foreign exchange, monetary fund, money markets, inflation targeting, interest rate targeting, monetary aggregate, money demand, money market, monetary policy strategy, foreign currency, monetary policy instruments, open market operations, monetary targeting, liquidity management, reserve requirements, monetary economics, money stock, reserve ratios, monetary phenomenon, monetary policy implementation, monetary approach, demand for money, monetary survey, monetary aggregates, alternative monetary policy frameworks, monetary management, monetary conditions, inflation target, low inflation, monetary targets, money supply, government securities, monetary policy strategies, monetary policy frameworks, monetary model, monetary policy instrument, monetary analysis, high inflation, monetary gold, monetary policy decisions, money growth, monetary transmission, monetary policy regimes, government securities markets, open market sales, sdr holdings, monetary relations, inflationary policy, monetary policy framework, annual inflation, increase in interest rates, monetary transmission mechanism, price stability
