Verbos de movimento, preposições direcionais e escalas

Prepositions para and até are apparently similar in some contexts, but they give rise to distinct interpretations that are related to the aspectual profile of the predications. This work aims to explore the differences between para and até regarding the telicity of the predications projected by verbs of movement of the type caminhar. Two theoretical perspectives are compared and the data presented suggest that the contribution of these prepositions to the telicity of the predications can be described in a more accurate way by using the notion of 'scale', in a similar way to apparently unrelated constructions such as Degree Achievements

Converse to the Parter–Wiener theorem: The case of non-trees

AbstractThrough a succession of results, it is known that if the graph of an Hermitian matrix A is a tree and if for some index j, λ∈σ(A)∩σ(A(j)), then there is an index i such that the multiplicity of λ in σ(A(i)) is one more than that in A. We exhibit a converse to this result by showing that it is generally true only for trees. In particular, it is shown that the minimum rank of a positive semidefinite matrix with a given graph G is ⩽n-2 when G is not a tree. This raises the question of how the minimum rank of a positive semidefinite matrix depends upon the graph in general

Fiscal episodes in the economic and monetary union: Elasticities and non-Keynesian effects

We estimate short- and long-run elasticities of private consumption for fiscal instruments, using a fixed-effects model for the 19 Euro area countries during the period of 1960–2017, to assess how fiscal elasticities vary during fiscal episodes. According to the results, positive ‘tax revenue’ elasticities indicate that consumers have Ricardian behaviour, whereby they perceive an increase in taxation to be a sign of future government spending. ‘social benefits’ appear to have a non-Keynesian effect on private consumption. In addition, using a narrative approach to identify fiscal consolidations, it is seen that private consumption continues to exhibit a non-Keynesian response to tax increases, both in the short and long-run, and ‘other expenditures’ have a recessive impact during ‘normal times’. Furthermore, ‘social benefits’ are more contractionary in consolidations than in both expansions and ‘normal times’. In addition, after the launch of the Economic and Monetary Union, expansionary fiscal consolidations became harder to observe, and ‘other expenditure’ and ‘investment’ lost their non-Keynesian role.info:eu-repo/semantics/publishedVersio

Sovereign yield spreads in the EMU : crisis and structural determinants

We use a panel of 11 EMU countries in the period 2000-2014 to assess the importance of political and economic determinants as explanatory factors in sovereign bond yield spreads. According to the results, there is evidence that those spread determinants gained importance after the beginning of the financial crisis. Following the crisis, the debt ratio, fiscal balance, expenditure on pension funds, the level of liquidity, GDP growth rate, and structural reforms have become relevant determinants of sovereign spreads, while fiscal rules have reduced spreads.info:eu-repo/semantics/publishedVersio

Fiscal multipliers in the Eurozone: an SVAR analysis

We compute the value of fiscal multipliers (for government primary expenditure, Income and wealth taxes and for Production and import taxes) in the Eurozone countries since the creation of the currency union (2000Q1-2016Q4), in order to understand how the values can vary according to the public debt level, the pace of economic growth, and the output gap. Imposing quarterly fiscal shocks, the results showed that government expenditure had a positive effect on output, with an annual accumulated multiplier of 0.44, whereas tax multipliers presented negative signs: the Income and wealth and the Production and import taxes stood at −0.11 and −0.55, respectively. Furthermore, the spending multiplier showed a higher value for countries with lower levels of public debt, during recessions, and in countries with negative output gaps. On the other hand, tax shocks seemed to be recessive in highly indebted countries and those facing positive output gaps.info:eu-repo/semantics/publishedVersio

Fiscal multipliers in the Eurozone : a SVAR analysis

We compute the value of fiscal multipliers (for government primary expenditure, Income and wealth taxes and for Production and import ones) in the Eurozone countries since the creation of the currency union (2001Q1-2016Q4), and to understand how the values may vary according to the public debt level, the rhythm of economic growth and the output gap. Imposing quarterly fiscal shocks in the period 2000-2016, the results shown that the government expenditure had a positive effect on output, with an annual accumulated multiplier of 0.64 while the tax multipliers presented negative signs - the Income and wealth and the Production and import taxes stood at -0.10 and -0.32, respectively. Furthermore, the multipliers shown higher values for countries with higher levels of public debt (to small levels, the expenditure multiplier is close to zero and the tax multipliers seem to have positive signs), during recessions, and in countries with positive output gaps.info:eu-repo/semantics/publishedVersio
