Balance sheet expansionary policies in the Euro Area : macroeconomic impacts and a vulnerable versus non-vulnerable comparison : a Bayesian structural VAR approach
Employing a Bayesian structural vector autoregressive (VAR) model, we estimate the impact
of the European Central Bank’s (ECB) balance sheet expansionary policies (BSEP) on a range
of economic and financial variables including real GDP, inflation, long-term sovereign bond
yields, systemic stress, unemployment, bank loans, and equity markets in the period from
2009:Q1 to 2021:Q4. The main conclusion from this study is that more vulnerable euro area
countries had larger magnitudes in desirable impulse responses to BSEPs shocks. To reach
this conclusion, we estimated the same model for 16 euro area countries and used maximum,
minimum, and cumulative impulse responses to assess the heterogenous responses to BSEPs
across member states. We then attempt to find correlations of impulse responses with measures
of financial and economic vulnerability such as debt-to-GDP ratios, unemployment, GDP per
capita (PPP), and tier 1 bank capital ratios. Our results suggest that the magnitude of the
responses are more pronounced in countries with higher levels of vulnerability. These findings
are akin to theoretical assumptions that suggest that unconventional monetary policies are
most effective in periods of severe systemic stress.info:eu-repo/semantics/publishedVersio
Impacts of Basel III announcements on European bank business models
The Basel regulation put forth by the Basel Committee of Banking Supervision (BCBS) is an
ambitious endeavor that aims at regulating the banking industry worldwide. The Basel III
accord introduced in 2010 is the latest iteration of this effort. Implementation of Basel III is
well underway today and programmed to take full effect in 2019. The criticism towards Basel
III is mainly pointed towards the negative impact it could have on the economy and the profitability
of banking institutions. In addition, the impacts on different banking business models
could be heterogeneous, benefitting some models more than others. The main question this
thesis tries to answer is if wealth effects on European exchange traded banks brought by Basel
III will be negative and if different business models will be impacted differently. To answer
this question a group of European banks were selected. Bank business models were assigned
using the k-means clustering algorithm where banks are clustered into traditional vs.
non-traditional categories depending on the asset and liability structure of the balance sheet.
An event study is then conducted to measure the wealth effects caused by the introduction of
Basel III on an aggregate level and by business model. The event studies are conducted on six
key dates from press releases by the BCBS to better capture the full effects of Basel III. Lastly,
a regression model is used to check whether there is any relationship between the abnormal
returns on the pre-specified event dates and bank business models. This thesis finds that
impacts on different event dates were not homogenous: some resulted in positive abnormal
returns and some negative therefore it was not possible to conclude if the impact of Basel III
was negative on European exchange traded banks. From the results, it was not possible to
conclude if any business model is impacted more or less severely by Basel III. The results
suggest that there are more dynamics at play that could influence the value of exchange traded
European banks
Unconventional monetary policy in the Euro Area. Impacts on loans, employment, and investment
Using a difference-in-differences identification strategy on a micro panel at the bank and firm level, we study the transmission effectiveness of ECB’s large-scale asset purchasing programs programs (i.e. APP and PEPP) in the Euro area. Our findings show: first, balance sheet composition of banks is an important determinant of monetary policy transmission. We tested this hypothesis by showing that banks more exposed to government debt securities had higher loan growth than less exposed banks after the APP announcement. By extension, this could lead to heterogeneous economic impacts depending on the geographical location of exposed banks. For the PEPP, contrary to the APP, we did not find a portfolio-rebalancing channel for banks that were more exposed to government debt securities. Second, using balance sheet data on corporates, we verify that firms that borrowed more increased employment and fixed capital investment, albeit to a lesser degree than before the APP announcement. Furthermore, our sample shows that corporations in countries with banks more exposed to government debt securities had higher borrowing growth and fixed capital growth versus countries with less exposed banks.info:eu-repo/semantics/publishedVersio
Do the projected fiscal deficits play a role in ECB monetary policymaking?
We estimate a large number of alternative monetary policy reaction functions for the ECB in order to robustly
find if fiscal stance matters for the monetary policy conduct. We use GMM and SVAR methods to estimate
inflation-output reaction functions with and without a fiscal deficit indicator from 2001 until 2022 with the
thick-modelling approach. The results revealed that ECB actions have exhibited desirable stabilising monetary
policy properties and have generally been found to be consistent with the Taylor principle. Most importantly,
the projected euro area fiscal deficit usually is not statistically significant in explaining ECB monetary policy
stance. Nevertheless, when the fiscal deficit indicator is statistically significant, the sign of its coefficient is
always positive, implying that increasing deficits lead to a more restrictive monetary policy stance. These
findings speak against the “fiscal dominance” regime in the euro area where monetary policy is single and
fiscal policies are decentralised. The results remain qualitatively similar independent of the precise
specification of the GMM and SVAR models and if the sample period is shortened from 2012.info:eu-repo/semantics/publishedVersio
THE INFLUENCE OF SWIMMING VELOCITY ON THE KINEMATIC CHARACTERISTICS OF BACKSTROKE SWIMMING
Under standard workout conditions, swimmers spend most of their time swimming at rates significantly lower than racing speed. Specificity of training is not just a metabolic problem, but also a technical and a kinesiological one. The purpose of this study was to determine to what extent swimming the backstroke at different speeds implies a change in the stroke pattern and in the kinematics of the propulsive movements. We also studied the technical characteristics associated with performance in short distance efforts. A third aim of this study was to compare the intra-cycle velocity variation of the center of gravity of the body to the intra-cycle velocity variation of the hip point.
Seven well-trained male swimmers participated in this study (age: 14.71±0.76 years, height: 1.74±0.39 m, body mass: 63.14±5.52 kg, %FAT: 15.40±1.81). Each subject performed 3 x 50 m backstroke repeats with 15 min of rest at a velocity corresponding to 90% (v90), 95% (v95) and 100% (vmax) of best performance in the 50 m backstroke. The swimmers were filmed on the sagittal plane, underwater and above the water, with synchronized cameras (60 Hz). Images were mixed and then digitized for further analysis using the APAS system.
Peak mean horizontal velocities of the hand occurred during the upsweep at v90 and v95 and during the finish/exit at vmax. Total stroke duration decreased from v90 to v100 due to the shorter duration of the downsweep, the final downsweep and the finish/exit, but the relative duration of the phases did not show any significant changes. Increasing velocity caused an increase in the distance between point of entry into the water and point of exit of the hand from the water, but mean horizontal pulling length decreased. Swimming velocity at sub-maximal paces correlated well to mean body velocity at the upsweep, but at vmax, the highest association was to body velocity at the final downsweep. Maximal velocity in the 50 m backstroke was inversely correlated to the range of intra-cycle velocity variations of the body center of gravity. This parameter showed a poor individual correlation to the hip velocity variation (r=0.58 ± 0.18). The correlation between the coefficient of variation of the hip and the center of gravity intra-cycle velocities had, on the contrary, a high significance.
Movement of temporal and spatial structures seem to vary little with velocity changes in swimmers who have attained a good stabilization of motor execution. In fast swimming, nevertheless, swimmers apparently achieve a greater anterioposterior stabilization of the hand, which may indicate more pronounced lift oriented sculling actions, and performance becomes more dependent on the final portion of the underwater path. The variation of the mean velocity of the hip cannot be used for quantification of the changes of body velocity from phase to phase, but a coefficient of variation (SD . mean-1 . 100) of intra-cycle hip velocity seems to be an adequate indicator of the intra-cycle velocity variation of the body center of gravity
The monte Molião cistern Lagos, Portugal
Conhecida desde o século XIX, a cisterna de Monte
Molião constitui o elemento arquitectónico mais destacado
do sítio e o único equipamento putativamente público ali documentado até ao momento. A sua escavação em 2011 e 2014
permitiu obter importantes dados sobre a sua tipologia e as
técnicas empregues na sua construção, bem como documentar a estratigrafia correspondente à sua colmatação. Foi assim
possível determinar que esta estrutura corresponde ao modelo
dito a bagnarola, de origem púnica, podendo datar-se do final
da Idade do Ferro ou de Época Romana Republicana, tendo
sido sujeita a reparações durante este último período. Por outro lado, o último período de utilização desta cisterna parece
ter-se verificado entre o Principado de Augusto e o reinado de
Tibério, seguindo-se um período de abandono e o seu eventual entulhamento, datado pelos materiais aqui estudados da
segunda metade do século I.Known since the 19th century, the cistern of Monte
Molião is the most notable architectural element in the site
and the only likely public infrastructure identified so far in
this settlement. Its excavation, undertaken in 2011 and 2014,
has brought to light important data about its typology and
construction techniques; a complete stratigraphic sequence
corresponding to its filling has also been documented. This
structure can be attributed to the so-called a bagnarola model
which originated in the Punic world and could have been constructed either in the Late Iron Age or in the Roman Republican period, having also been repaired in the latter period. Its
last period of use, on the other hand, seems to fall within the
reign of Augustus or Tiberius, being followed by a period of
abandonment and eventually by its intentional filling which,
based on the material studied here, can be dated to the second
half of the 1st centuryCâmara Municipal de Lago
Recent Advances in Welding
Welding is a conventional joining process that has followed the recent developments in other manufacturing processes, continuing to be an extremely used and investigated process. Several technologies developed in other areas of knowledge have converged in the area of welding, allowing significant improvements in the quality of the products obtained and in the increased productivity of the processes. Although some techniques have been implemented and studied for several decades, the interest of researchers in welding has not diminished, as it can be seen through new processes that have emerged, such as Friction Stir Welding, in addition to many other notable developments in welding processes which apparently seemed to have reached their final stage of maturity.
This work brings together a set of very interesting works, being a living proof that welding continues to be heavily investigated and that the developments around this manufacturing process are constantly emerging. Because the materials continue to evolve and the technology around welding also continues to develop at a very good pace, studies on the weldability of new materials and the application of new techniques and technologies to already well known welding processes does not stops happening.
The editors are proud to have collected this set of works that can help scholars and researchers to broaden their knowledge in the field of welding, thus contributing to the creation of a knowledge base that allows researchers to start new investigations and achievements in the coming decades.info:eu-repo/semantics/publishedVersio
Assessing NoSQL databases for telecom applications
The constant evolution of access technologies are
turning Internet access more ubiquitous, faster, better and
cheaper. In connection with the proliferation of Internet access,
Cloud Computing is changing the way users look at data, moving
from local applications and installations to remote services,
accessible from any device. This new paradigm presents numerous
opportunities that even traditional businesses like telecoms
cannot ignore, in particular, enabling new and more cost effective
solutions to old problems.
The work presented in this paper provides a detailed description
of how a telecom application can be migrated to a NoSQL
database. Particularly, by pointing out the necessary change of
how we reason about data as well as the data structures that
support it, in order to take full advantage of Cloud Computing.
In addition, we also present a preliminary evaluation of different
data persistency paradigms based on a fully tunable simulation
platform that mimics the operation of a telecom business
