It uses a methodology developed by Sims, Waggoner e Zha (2008), which is a Bayesian estimation procedure that allows for state (regime) dependent endogenous change in models parameters and the states follow a markovian process of regime change. It estimates a Structural Bayesian VAR model with Markov Switching regimes (MS-SBVAR).

The software MATLAB / Dynare was used to estimate the model and the results suggest the occurrence of 2 or 3 regimes in the two best data fitting models. The different estimated multipliers show the correct signs and, as expected, they are higher for exogenous shocks to public administrations fixed capital gross formation which are effective, since they have values higher than one and long-term impact on GDP - when compared with exogenous shocks to public administrations consumption, which have a small persistence and are ineffective (less than one), and a negative and persistence response of GDP to shocks in net tax burden. The results do not also show a higher fiscal multiplier in regimes with higher models residuals variance.

On the dynamic effects of fiscal policyTsoungui Belinga, Vincent de Paul 05 1900 (has links)
Dans le sillage de la récession mondiale de 2008-09, plusieurs questions ont été soulevées dans la littérature économique sur les effets à court et à long terme de la politique budgétaire sur l’activité économique par rapport à son signe, sa taille et sa durée. Ceux-ci ont des implications importantes pour mieux comprendre les canaux de transmission et l’efficacité des politiques budgétaires, avec la politique monétaire étant poursuivi, ainsi que pour leurs retombées économiques. Cette thèse fait partie de ce regain d’intérêt de la littérature d’examiner comment les changements dans la politique budgétaire affectent l’activité économique. Elle repose alors sur trois essais: les effets macroéconomiques des chocs de dépenses publiques et des recettes fiscales, les résultats macroéconomiques de l’interaction entre les politiques budgétaire et monétaire et le lien entre la politique budgétaire et la répartition des revenus.
Le premier chapitre examine les effets des chocs de politique budgétaire (chocs de dépenses publiques et chocs de recettes fiscales) sur l’économie canadienne au cours de la période 1970-2010, en s’appuyant sur la méthode d’identification des restrictions de signe développée par Mountford et Uhlig [2009]. En réponse à la récession mondiale, les autorités fiscales dans les économies avancées, dont le Canada ont généralement mis en oeuvre une approche en deux phases pour la politique budgétaire. Tout d’abord, ils ont introduit des plans de relance sans précédent pour relancer leurs économies. Par exemple, les mesures de relance au Canada, introduites à travers le Plan d’action économique du Canada, ont été projetées à 3.2 pour cent du PIB dans le budget fédéral de 2009 tandis que l’ "American Recovery and Reinvestment Act"(ARRA) a été estimé à 7 pour cent du PIB. Par la suite, ils ont mis en place des plans d’ajustement en vue de réduire la dette publique et en assurer la soutenabilité à long terme. Dans ce contexte, évaluer les effets multiplicateurs de la politique budgétaire est important en vue d’informer sur l'efficacité de telles mesures dans la relance ou non de l'activité économique. Les résultats montrent que les multiplicateurs d'impôt varient entre 0.2 et 0.5, tandis que les multiplicateurs de dépenses varient entre 0.2 et 1.1. Les multiplicateurs des dépenses ont tendance à être plus grand que les multiplicateurs des recettes fiscales au cours des deux dernières décennies. Comme implications de politique économique, ces résultats tendent à suggérer que les ajustements budgétaires par le biais de grandes réductions de dépenses publiques pourraient être plus dommageable pour l'économie que des ajustements budgétaires par la hausse des impôts.
Le deuxième chapitre, co-écrit avec Constant Lonkeng Ngouana, estime les effets multiplicateurs des dépenses publiques aux Etats-Unis en fonction du cycle de la politique monétaire. Les chocs de dépenses publiques sont identifiés comme étant des erreurs de prévision du taux de croissance des dépenses publiques à partir des données d'Enquêtes des prévisionnistes professionnels et des informations contenues dans le "Greenbook". L'état de la politique monétaire est déduite à partir de la déviation du taux des fonds fédéraux du taux cible de la Réserve Fédérale, en faisant recours à une fonction lisse de transition. L'application de la méthode des «projections locales» aux données trimestrielles américaines au cours de la période 1965-2012 suggère que les effets multiplicateurs des dépenses fédérales sont sensiblement plus élevées quand la politique monétaire est accommodante que lorsqu'elle ne l'est pas. Les résultats suggèrent aussi que les dépenses fédérales peuvent stimuler ou non la consommation privée, dépendamment du degré d’accommodation de la politique monétaire. Ce dernier résultat réconcilie ainsi, sur la base d’un cadre unifié des résultats autrement contradictoires à première vue dans la littérature. Ces résultats ont d'importantes implications de politique économique. Ils suggèrent globalement que la politique budgétaire est plus efficace lorsqu'on en a le plus besoin (par exemple, lorsque le taux de chômage est élevé), si elle est soutenue par la politique monétaire. Ils ont également des implications pour la normalisation des conditions monétaires dans les pays avancés: la sortie des politiques monétaires non-conventionnelles conduirait à des multiplicateurs de dépenses fédérales beaucoup plus faibles qu'autrement, même si le niveau de chômage restait élevé. Ceci renforce la nécessité d'une calibration prudente du calendrier de sortie des politiques monétaires non-conventionnelles.
Le troisième chapitre examine l'impact des mesures d'expansion et de contraction budgétaire sur la distribution des revenus dans un panel de 18 pays d'Amérique latine au cours de la période 1990-2010, avec un accent sur les deniers 40 pour cent. Il explore alors comment ces mesures fiscales ainsi que leur composition affectent la croissance des revenus des dernier 40 pour cent, la croissance de leur part de revenu ainsi que la croissance économique. Les mesures d'expansion et de contraction budgétaire sont identifiées par des périodes au cours desquels il existe une variation significative du déficit primaire corrigé des variations conjoncturelles en pourcentage du PIB. Les résultats montrent qu'en moyenne l'expansion budgétaire par la hausse des dépenses publiques est plus favorable à la croissance des revenus des moins bien-nantis que celle par la baisse des impôts. Ce résultat est principalement soutenu par la hausse des dépenses gouvernementales de consommation courante, les transferts et subventions. En outre ces mesures d’expansion budgétaire sont favorables à la réduction des inégalités car elles permettent d'améliorer la part des revenus des moins bien-nantis tout en réduisant la part des revenus des mieux-nantis de la distribution des revenus. En outre ces mesures d’expansion budgétaire sont favorables à la réduction des inégalités car elles permettent d'améliorer la part des revenus des moins bien-nantis tout en réduisant la part des revenus des mieux-nantis de la distribution des revenus. Cependant, l'expansion budgétaire pourrait soit n'avoir aucun effet sur la croissance économique ou entraver cette dernière à travers la hausse des dépenses en capital. Les résultats relatifs à la contraction budgétaire sont quelque peu mitigés. Parfois, les mesures de contraction budgétaire sont associées à une baisse de la croissance des revenus des moins bien nantis et à une hausse des inégalités, parfois l'impact de ces mesures est non significatif. Par ailleurs, aucune des mesures n’affecte de manière significative la croissance du PIB. Comme implications de politique économique, les pays avec une certaine marge de manœuvre budgétaire pourraient entamer ou continuer à mettre en œuvre des programmes de "filets de sauvetage"--par exemple les programmes de transfert monétaire conditionnel--permettant aux segments vulnérables de la population de faire face à des chocs négatifs et aussi d'améliorer leur conditions de vie. Avec un potentiel de stimuler l'emploi peu qualifié, une relance budgétaire sage par les dépenses publique courantes pourrait également jouer un rôle important pour la réduction des inégalités. Aussi, pour éviter que les dépenses en capital freinent la croissance économique, les projets d'investissements publics efficients devraient être prioritaires dans le processus d'élaboration des politiques. Ce qui passe par la mise en œuvre des projets d'investissement avec une productivité plus élevée capable de générer la croissance économique nécessaire pour réduire les inégalités. / In the wake of the 2008-09 Global Recession, several issues have been raised in the economic literature about the short and long-run effects of fiscal policy on economic activity with respect to its signs, its size and its duration. These have important implications to better understand the transmission channels and the effectiveness of fiscal policies, along with the monetary policy being pursued, as well as for their economic fallouts. This dissertation is part of this renewed strand of literature to assess how changes in fiscal policy affect economic activity. It therefore relies on three essays: the macroeconomic effects of government spending and tax revenue shocks, the economic outcomes of the interaction between fiscal and monetary policies and the nexus between fiscal policy and income distribution.
The first chapter examines the effects of fiscal policy shocks (government spending and tax revenue shocks) on the Canadian economy, building on the sign-restrictions-VAR approach developed by Mountford and Uhlig [2009]. In response to the Global Recession, fiscal authorities in advanced economies including Canada typically implemented a two-phase approach to fiscal policy. First, they introduced unprecedented stimulus packages to revive their economies. For instance, stimulus measures in Canada, introduced through Canada's Economic Action Plan, were projected at 3.2 percent of GDP in the 2009 federal budget while the American Recovery and Reinvestment Act (ARRA) was estimated at 7 percent of GDP. Following the stimulus, they shifted gears, adopting adjustment plans to reduce public debt and ensure long-term fiscal sustainability. Against this backdrop, examining the size of fiscal multiplier is important to informing the effectiveness of such policy measures in reviving or not economic activity. I find that tax-cut multipliers vary between 0.2 and 0.5, while spending multipliers range between 0.2 and 1.1. Spending multipliers tend to be larger than tax-cut multipliers over the last two decades. For policy implications, these results tend to suggest that fiscal consolidations through large spending cuts could be more harmful to the economy than tax-based fiscal adjustments.
The second chapter, co-written with Constant Lonkeng Ngouana, provides estimates of the US government spending multiplier over the monetary policy cycle. Government spending shocks are identified as forecast errors of the growth rate of government spending from the Survey of Professional Forecasters (SPF) and from the Greenbook record, further stripped from their predictable components. The state of monetary policy is inferred from the deviation of the Fed funds rate from the target rate, using a smooth transition function. Applying the local projections method to quarterly US data over the period 1965-2012, results show that the federal government spending multiplier is substantially higher under accommodative than non-accommodative monetary policy. The estimations also suggest that federal government spending may crowd-in or crowd-out private consumption, depending on the extent of monetary policy accommodation. The latter result reconciles---in a unified framework---apparently contradictory findings in the literature. These findings have important policy implications. They broadly suggest that fiscal policy is more effective when needed the most (e.g., at times of slack), if supported by monetary policy. They also have implications for the normalization of monetary conditions in advanced economies: the exit from UMP would lead to much lower federal government spending multipliers than otherwise, even if some amount of slack was to remain in the economy. This further highlights the need for a careful calibration of the timing of exit from unconventional monetary policy.
The third chapter examines the impact of fiscal expansion and fiscal contraction measures on income distribution in a panel of 18 Latin American countries over the period 1990-2010, with a focus on the bottom 40 percent. It therefore explores how these fiscal measures and their composition have affected the income growth of the bottom 40 percent, their income share growth and economic growth. Fiscal expansions and fiscal consolidations are identified by periods for which there is a significant change in the cyclically-adjusted primary deficit as share of GDP. I find that on average, expenditures-based fiscal expansion are more likely to increase the income of the bottom 40 percent than revenues-based fiscal expansion. This result is mainly driven by government current consumption, transfers and subsidies. In addition, these fiscal expansion measures help to reduce income inequality by improving the income share of the bottom segments of the population while reducing the top income share. However, fiscal expansion could either have no effect on economic growth or prevent the latter through capital expenditures increases. Results for fiscal consolidation are somewhat mixed. Sometime, fiscal consolidation is associated with a decline of the income growth of the less well-off and rising inequality, sometime the impact is non-significant. None of the fiscal contraction measures affects significantly GDP growth. These findings have important policy implications. Countries with some fiscal space could initiate or continue to implement safety nets program--like conditional cash transfer programs--necessary to prevent the vulnerable segment of the population to adverse shocks and to improve their living standards. With a potential of stimulating low-skill employment, a wise fiscal stimulus through government current consumption increases could also play a significant role to reduce income inequality. Also, to avoid capital expenditures that hinder economic growth, efficient public investment projects should be prioritized in the policy making process. This consists of implementing investment projects with higher productivity that can enhance economic growth necessary to reduce inequality.

[en] EXPECTATIONS AND THE COORDINATION OF MONETARY AND FISCAL POLICIES / [pt] EXPECTATIVAS E A COORDENAÇÃO DAS POLÍTICAS MONETÁRIA E FISCALCYNTIA FREITAS AZEVEDO 12 February 2019 (has links)
[pt] Essa tese discute o papel das expectativas dos agentes a respeito da
condução das políticas monetária e fiscal na determinação dos efeitos dessas
políticas, na dinâmica da economia e na volatilidades das variáveis macroeconômicas.
O primeiro capítulo mostra que considerar as expectativas dos
agentes a respeito de possíveis mudanças de regime tem efeitos importantes
nas respostas das variáveis macroeconômicas aos choques, mesmo que
essa mudança de regime não se materialize ao longo da trajetória observada
após o choque. O reconhecimento da possibilidade de mudanças de regime
também tem consequências importantes para a volatilidade das variáveis
endógenas que são mais altas do que as obtidas no modelo linear e muito
dependentes dos parâmetros de política escolhidos pelas autoridades fiscal
e monetária em cada regime. O segundo capítulo discute o papel das expectativas
a respeito das políticas futuras na determinação da profundidade de
uma crise quando a economia atinge o limite inferior de zero para as taxas
de juros nominais. Ele mostra que ao analisar o impacto de um estímulo
fiscal durante um episódios de taxa de juros zero, deve-se olhar para além
dos multiplicadores no curto prazo. Para ter efeitos positivos maiores, as
políticas monetária e fiscal devem durar mais do que a crise e precisam ser
coordenadas. O terceiro capítulo apresenta uma avaliação dos estímulos fiscais
em termos das perdas de bem-estar, tornando claro que essa avaliação
deve considerar não apenas o efeitos das políticas sobre a inflação e o produto
no curto prazo, mas também o valor presente descontado da inflação
e do produto nos períodos futuros. Ele também apresenta uma análise de
como se obtém o nível ótimo da taxa de juros nominal uma vez que a economia
não está mais em crise se a autoridade monetária pretende usar o
canal das expectativas para reduzir a profundidade da crise. / [en] This thesis discusses the role of agents expectations regarding the
conduction of monetary and fiscal policies in determining policy outcomes,
economic dynamics and the volatilities of macroeconomic variables. The first
Chapter shows that accounting for agents’ expectations of a possible regime
change has critical effects in the responses of macroeconomic variables to
shocks, even if this switch does not materialize itself along the path observed
after the shock. Recognizing the possibility of regime switches also have
important consequences for the volatilities of endogenous variables, which
are higher than those obtained in the linear model and very dependent
on the policy parameters chosen by monetary and fiscal authorities in
each regime. In the second Chapter, I discuss the role of expectations in
determining the depth of a crisis when the economy hits the zero lower
bound on nominal interest rates. I show that when analysing the impact of
a fiscal stimulus during a zero interest rate episode, there is more than just
short-run multipliers. To have larger positive effects on output and inflation,
monetary and fiscal policies should last longer than the duration of the shock
and be coordinated in their actions. The third Chapter presents a thoughtful
evaluation of a fiscal stimulus in terms of the implied welfare losses making
clear that it should account not only for the effects of policies on short-run
output and inflation, but also for the present discounted value of output
and inflation in future periods as well. It also analyses how to obtain the
optimal level for the nominal interest rate once the economy gets out of the
crisis state, if the monetary authority wants to use the expectations channel
to undermine the depth of the crisis.

Essays on Management of fiscal resources in developing and emerging countries / Décision publique et gestion des ressources budgétaires dans les pays en développement et émergents / Decizia publică și managementul resurselor bugetare în țările în dezvoltare și emergenteMustea, Lavinia Teodora 30 September 2015 (has links)
Une crise financière et économique sans précèdent est apparue aux Etats-Unis en 2007, a progressé rapidement et s’est propagée à de nombreux pays dans le monde. L’instrument budgétaire a été largement utilisé : dans un contexte de contagion financière, les gouvernements ont dû réagir en adoptant dans un premier temps des mesures visant à relancer l'économie, puis, dans un deuxième temps, face à l’endettement croissant, des mesures de stabilisation économique. L'objectif de cette thèse est de mettre en évidence l'importance des caractéristiques spécifiques à la fois régionales et nationales dans la prise de décision publique visant à stimuler la croissance économique. La thèse analyse la relation entre le PIB et le chômage, ainsi que les effets des programmes de relance budgétaire. Dans la première partie, la loi d'Okun est examinée, au niveau régional, dans trois pays émergents d’Europe Centrale et de l’Est. Dans la deuxième partie, un éclairage particulier est porté sur le concept de multiplicateur budgétaire et ses implications de politique économique. Dans la troisième partie, les multiplicateurs budgétaires sont calculés dans des pays émergents, en particulier ceux des régions méditerranéennes et d’Europe Centrale et de l’Est. La thèse mobilise les outils de l’économétrie sur séries temporelles et sur panels de longue durée. / An unprecedented financial and economic crisis irrupted in the US in 2007, and has rapidly grown and spread to many countries around the world. The financial instrument has been widely used: in a context of financial contagion, governments have initially reacted by adopting measures to revive the economy, and then, secondly, facing mounting debt, implemented economic stabilization policies. The goal of this thesis is to highlight the importance of specific features both at regional and national level in the public decision making to stimulate economic growth. The thesis analyses the relationship between GDP and unemployment, as well as the effects of fiscal stimuli. In the first part, Okun’s law is examined at regional level in three emerging Central and Eastern European countries. In the second part, the emphasis is given to the concept of fiscal multiplier and its policy implications. In the third part, fiscal multipliers are assessed in emerging countries, particularly those of the Mediterranean and the Central and Eastern Europe regions. The thesis makes use of time series and panel econometrics methods.

Interactions between fiscal policy and real economy in the Czech Republic: a quantitative analysis / Kvantitativní analýza interakcí fiskální politiky a reálné ekonomiky v České republiceValenta, Vilém January 2004 (has links)
After many decades, macroeconomic effects of fiscal policy have returned to the centre of the economic policy debate. Both automatic fiscal stabilizers and discretionary fiscal stimuli have been used to support aggregate demand during the recent global economic crisis with a subsequent need for large-scale fiscal consolidations. In this context, a proper assessment of the size of automatic fiscal stabilizers and fiscal multipliers represents a key input for fiscal policymaking. This dissertation provides a quantitative analysis of the interactions between fiscal policy and real economy in the Czech Republic. The impact of real economy developments on public finances is assessed based on the methods of the OECD, the European Commission and the ESCB for the identification of general government structural balances, i.e. balances adjusted for effects of the economic cycle and net of one-off and other temporary transactions. I find that the underlying fiscal position, as approximated by the government structural balance, was mostly below the level stabilising the debt-to-GDP ratio since mid-1990s. An indistinct improvement in the structural balance can be identified in the period 2004--2007, which was subsequently reversed by the adverse structural impact of the world economic crisis. At the same time, dynamics of unadjusted fiscal balance was largely determined by one-off transactions in the past. The effects of fiscal policy on real economy are analysed using the structural VAR approach. I find that an increase in government spending has a temporary positive effect on output that peaks after one to two years with a multiplier of around 0.6. Tax multiplier appears to be small and, in contrast to standard Keynesian assumptions, positive. Government spending is supportive to private consumption, contradicting the hypothesis of Ricardian equivalence, but it crowds out private investment in the short run. The results should be interpreted with caution, as the analysis is complicated by rapidly changing economic environment in the period of the economic transition, relatively short available time series and a large number of one-off fiscal transactions.

Essays on Government Growth, Fiscal Policy and Debt SustainabilityKuckuck, Jan 29 April 2015 (has links)
The financial crisis of 2007/8 has triggered a profound debate about public budget finance sustainability, ever-increasing government expenditures and the efficiency of fiscal policy measures. Given this context, the following dissertation provides four contributions that analyze the long-run growth of government spending throughout economic development, discuss potential effects of fiscal policy measures on output, and provide new insights into the assessment of debt sustainability for a variety of industrialized countries.
Since the breakout of the European debt crisis in 2009/2010, there has been a revival of interest in the long-term growth of government expenditures. In this context, the relationship between the size of the public sector and economic growth - often referred to as Wagner's law - has been in the focus of numerous studies, especially with regard to public policy and fiscal sustainability. Using historical data from the mid-19th century, the first chapter analyzes the validity of Wagner's law for five industrialized European countries and links the discussion to different stages of economic development. In line with Wagner's hypothesis, our findings show that the relationship between public spending and economic growth has weakened at an advanced stage of development. Furthermore, all countries under review support the notion that Wagner's law may have lost its economic relevance in recent decades.
As a consequence of the 2007/8 financial crisis, there has been an increasing theoretical and empirical debate about the impact of fiscal policy measures on output. Accordingly, the Structural Vector Autoregression (SVAR) approach to estimating the fiscal multipliers developed by Blanchard and Perotti (2002) has been applied widely in the literature in recent years. In the second chapter, we point out that the fiscal multipliers derived from this approach include the predicted future path of the policy instruments as well as their dynamic interaction. We analyze a data set from the US and document that these interactions are economically and statistically significant. In a counterfactual simulation, we report fiscal multipliers that abstract from these dynamic responses. Furthermore, we use our estimates to analyze the recent fiscal stimulus of the American Recovery and Reinvestment Act (ARRA).
The third chapter contributes to the existing empirical literature on fiscal multipliers by applying a five-variable SVAR approach to a uniform data set for Belgium, France, Germany, and the United Kingdom. Besides studying the effects of expenditure and tax increases on output, we additionally analyze their dynamic effects on inflation and interest rates as well as the dynamic interaction of both policy instruments. By conducting counterfactual simulations, which abstract from the dynamic response of key macroeconomic variables to the initial fiscal shocks, we study the importance of these channels for the transmission of fiscal policy on output. Overall, the results demonstrate that the effects of fiscal shocks are limited and rather different across countries. Further, it is shown that the inflation and interest rate channel are insignificant for the transmission of fiscal policy. In the field of public finances, governmental budgetary policies are among the most controversial and disputed areas of political and scientific controversy. The sustainability of public debt is often analyzed by testing stationarity conditions of government's budget deficits.
The fourth chapter shows that this test can be implemented more effectively by means of an asymmetric unit root test. We argue that this approach increases the power of the test and reduces the likelihood of drawing false inferences. We illustrate this in an application to 14 countries of the European Monetary Union as well as in a Monte Carlo simulation. Distinguishing between positive and negative changes in deficits, we find consistency with the intertemporal budget constraint for more countries, i.e. lower persistence of positive changes in some countries, compared to the earlier literature.
