It is well known that fiscal policy can counter-cyclically smooth out the effect of unexpected shocks and public deficit volatility may reflect the (optimal) policy response to them. However, the welfare losses associated to fiscal instability are also an important challenge for many countries, as it typically implies an inefficient allocation of resources, higher sovereign risk premium and an inadequate provision of public services. In this paper, we empirically analyze the political, institutional, and economic sources of public deficit volatility. Using the system-generalized method-of-moments (GMM) estimator for linear dynamic panel data models and a sample of 125 countries analyzed from 1980 to 2006, we show that higher public deficit volatility is typically associated with higher levels of political instability and less democracy. In addition, public deficit volatility tends to be magnified for small countries, in the outcome of hyper-inflation episodes and for countries with a high degree of openness.

Using a panel of annual data for 20 countries we show that synchronized fiscal consolidation (stimulus) programmes in different countries make their business cycles more closely linked, especially in the case of fiscal adjustments lasting 2 or 3 years. We also find: (i) little evidence of decoupling when an inflation targeting regime is unilaterally adopted; (ii) an increase in business cycle synchronization when countries fix their exchange rates and become members of a monetary union; (iii) a positive effect of bilateral trade on the synchronization of business cycles

We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. Consequently, the attempts of fiscal policy to mitigate stock price developments (e.g. via taxes on capital gains) may severely de-stabilize housing markets. The empirical findings also point to significant fiscal multiplier effects in the context of severe housing busts, which gives rise to the importance of the implementation of fiscal stimulus packages. In addition, our results suggest that when governments run a budget deficit, they place an upward pressure on real interest rates, which "crowds-out" private consumption and investment. In contrast, during bust periods, unexpected variation in the fiscal stance crowds-in private spending, which reflects the "direct" and "indirect" effects of policy actions impact arising from a downward movement in real interest rates and an upward revision in price level expectations.

In this paper, we assess the impact of fiscal policy discretion on economic activity in the short and medium-term. Using a panel of 132 countries from 1960 to 2008, we find that fiscal policy discretion provides a net stimulus to the economy in the short-run and crowding-in effects are amplified once crisis episodes are controlled for– in particular, banking crises - giving a great scope for fiscal policy stimulus packages. However, crowding-out effects take over in the long-run – especially, in the case of debt crises -, in line with the concerns about long-term debt sustainability.

Using quarterly data for a group of 20 industrialized countries and both continuous- and discrete-time duration models, we show that financial crisis recessions are associated with a two- to three-fold increase in the likelihood of the end of a housing boom. Additionally, recessions preceded by booms in mortgage credit are especially damaging, as their occurrence coincides with an increase in the duration of housing market slumps of almost 90%.

Using annual data for 13 European countries over the period 1980-2008, we assess the impact of national fiscal consolidations on the income inequality of European regions. Regional dispersion increases in the outcome of consolidation episodes, particularly, when packages are more severe and implemented through spending cuts rather than tax rises. From a policy perspective, these findings suggest that fiscal consolidations driven by reductions in government spending can exacerbate regional disparities and may ultimately counteract the European policy efforts to promote territorial cohesion. Our results are robust to alternative inequality measures, the occurrence of crisis episodes and the exclusion of fiscal outliers.

In this paper, we assess the characteristics of the housing market and its main determinants. Using data for 20 industrial countries over the period 1970Q1–2012Q2 and a discrete-time Weibull duration model, we find that the likelihood of the end of a housing boom or a housing bust increases over time. Additionally, we show that the different phases of the housing market cycle are strongly dependent on the economic activity, but credit market conditions are particularly important in the case of housing booms. The empirical findings also indicate that although housing booms have similar lengths in European and non-European countries, housing busts are typically shorter in European countries. The use of a more flexible specification for the hazard function that is based on cubic splines suggests that it evolves in a nonlinear way. From a policy perspective, our study can be useful for predicting the timing and the length of housing boom–bust cycles. Moreover, it highlights the importance of monetary policy by influencing lending rates and affecting the likelihood of occurrence of housing booms.

"Published online: 19 Oct 2015", Using a panel of 13 advanced economies for the period 1980–2012, we find that periods of impaired financial intermediation mainly accrue to maturity mismatches in sovereign debt. Thus, a higher (lower) share of short-term (medium and long-term) debt leads to an increase in the financial stress index. From a policy perspective, our work suggests that debt management policies translated into longer average maturities of sovereign debt not only reduce the expected debt servicing cost, but also mitigate strains in the financial sector., FCT Fundação para a Ciência e Tecnologia (COMPETE 2020, PORTUGAL 2020, FEDER)

Building on a narrative approach to identify episodes of fiscal consolidation, data for a group of 17 industrial countries over the period 1978-2009 and continuous-time duration models, we find evidence suggesting that the likelihood of a fiscal consolidation ending increases over time, but only for programs that last less than six years. Additionally, fiscal consolidations tend to last longer in non-European than in European countries. Our results emphasize that chronic fiscal imbalances might lead to a vicious austerity cycle, while discipline in the behaviour of fiscal authorities is a means of achieving credible and shorter adjustment measures. Therefore, fiscal fatigue is likely to compromise the implementation and successfulness of fiscal consolidation programmes., COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)

Using data for a large panel of countries, this paper investigates the role played by income inequality and fiscal stimuli episodes in shaping the likelihood of political stability. By means of Tobit estimations, we show that a rise in inequality increases the probability of government crises. However, such adverse distributional effect is reduced when expansionary or increasingly expansionary fiscal stimuli episodes or successful fiscal stimuli programs are put in place., COMPETE2020, Feder, Portugal 2020, FCT

"Published online: 15 Aug. 2014", Using a panel of developed and developing countries and data for the period 1980 to 2005, we find that debt crises trigger financial reforms.We also show that (i) when general economic conditions deteriorate, financial reforms become more likely to take place; (ii) IMF-stabilization programmes and sovereign debt restructurings favour the implementation of financial reforms; and (iii) the quality of economic institutions strongly boosts financial reforms., COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)

We develop a novel empirical approach to assess the effect of discretionary fiscal policy on private spending consisting of three stages: 1) extract the discretionary component of fiscal policy by estimating a fiscal policy rule; 2) use the residuals of the first-stage regression to investigate the existence of crowding-in and/or crowding-out effects both in the short and the medium term; and 3) condition the response of private spending on a set of country characteristics. We find that an expansion in discretionary fiscal policy boosts growth in the short term, but is detrimental in the medium term. In addition, the empirical findings suggest that the effect of discretionary fiscal policy on private spending varies across regions and income groups, and depends on countries' economic characteristics such as the level of economic development, trade openness, government and country size.

This paper analyzes the dynamic impact of discretionary government consumption purchases on private demand. Using a panel of 132 countries from 1960 to 2008, we find that while discretionary changes in government consumption lead to crowding-in effects in the short run, crowding-out effects take over in the medium run. In addition, we also find that both short-term crowding-in and mediumterm crowding out effects are amplified once we control for periods of crisis., COMPETE; QREN; FEDER; Fundação para a Ciência e a Tecnologia (FCT)

Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. As a result, the attempts of fiscal policy to mitigate stock price developments may severely de-stabilize housing markets. The empirical findings also point to: (i) a contractionary effect of fiscal policy on output in line with the existence of crowding-out effects; (ii) a weakening of the effectiveness of fiscal policy in recent times; (iii) significant fiscal multiplier effects in the context of severe housing busts; and (iv) an increase of the sensitivity of asset prices to fiscal policy shocks following the process of financial deregulation and mortgage liberalization. Finally, the evidence suggests that changes in equity prices may help governments towards consolidation of public finances., Fundação para a Ciência e a Tecnologia (FCT) - Programa Operacional Ciência e Inovação 2010 (POCI 2010), Fundo Europeu de Desenvolvimento Regional (FEDER)

"Available online 1 August 2014", We test for nonlinear effects of asset prices on the fiscal policy of threemajor European economies (the UK, Italy and Spain).We model primary government spending and government revenue as time-varying transition probability Markovian processes (TVPMS). We find that while in Italy fiscal policy is substantially neutral vis-à-vis asset price movements, fiscal authorities in the UK and Spain seem to track the dynamics of wealth. In particular, revenue-based fiscal policy interventions in the UK are particularly effective in counteracting shocks in the asset markets induced by sharp wealth fluctuations. Similarly, in Spain, the spending-side of the fiscal policy plays a dominant role in stabilizing stock and housing markets., COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)

We use data for a panel of 60 countries over the period 1980–2005 to investigate the main drivers of the likelihood of structural reforms. We find that: (i) external debt crises are the main trigger of financial and banking reforms; (ii) inflation and banking crises are the key drivers of external capital account reforms; (iii) banking crises also hasten financial reforms; and (iv) economic recessions play an important role in promoting the necessary consensus for financial, capital, banking and trade reforms, especially in the group of OECD-countries. Additionally, we also observe that the degree of globalisation is relevant for financial reforms, in particular in the group of non-OECD countries. Moreover, an increase in the income gap accelerates the implementation of structural reforms, but increased political fragmentation does not seem to have a significant impact., COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)

This paper analyzes the impact of financial sector policy changes on the dynamics of public debt. Using a panel of 89 countries from 1973 to 2005, we find that while the implementation of (large) financial liberalisation policies significantly raises the public debt growth rate, the adoption of financial re-regulation measures leads to a mild reduction of public debt. Looking at the different typologies of financial sector policy changes, we show that stricter banking supervision, privatisations and restrictions to international capital flows contribute to a fast decline of the growth rate of public debt. In contrast, the removal of entry barriers and the elimination of interest rate controls boost public debt growth. Finally, our results confirm that financial re-regulation is more likely to succeed when inflation is high, while large financial liberalisation measures significantly raise public debt when economic growth is low. Our results are robust to various estimation techniques and model specifications and to the inclusion of different control variables., COMPETE, QREN, FEDER, FCT

We assess the existence of duration dependence in the likelihood of an end in housing booms, busts, and normal times. Using data for 20 industrial countries and a continuous-time Weibull duration model, we find evidence of positive duration dependence suggesting that housing market cycles have become longer over the last decades. Then, we extend the baseline Weibull model and allow for the presence of a change-point in the duration dependence parameter.We show that positive duration dependence is present in booms and busts that last less than 26 quarters, but that does not seem to be the case for longer phases of the housing market cycle. For normal times, no evidence of change-points is found. Finally, the empirical findings uncover positive duration dependence in housing market booms of European and non-European countries and housing busts of European countries. In addition, they reveal that while housing booms have similar length in European and non-European countries, housing busts are typically shorter in European countries., COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)

We investigate the determinants of the volatility of fiscal policy discretion. Using a linear dynamic panel dataset model for 104 countries from 1980 to 2006 and a system-GMM estimator,we find that more government instability, less democracy and presidentialist systems increase the volatility of the discretionary component of fiscal policy. Additionally, we show that countries with a larger size, a smaller degree of financial openness, and a stable exchange rate system are more insured against the uncertainty about the conduct of fiscal policy. Our results are robust to various regional dummy variables, diferent sub-sets of countries and the presence of high inflation and crisis episodes., The authors would like to thank the following for helpful comments: the Editor, two anonymous referees and participants at the 2009 Annual Meeting of the European Economic Association and the Econometric Society, the Economic Policies Research Unit (NIPE) seminar organised by the University of Minho, the First International Symposium in Computational Economics and Finance (ISCEF 2010), the 2010 Annual Meeting of the European Public Choice Society, the workshop on ‘International Political Economy and Cross-Border Effects’ organised by Queen Mary University of London and the UECE Conference on Economic and Financial Adjustments in Europe.

Using a panel of 17 countries for 1978-2009, we find that tax-driven consolidations increase unemployment by 0.25 percentage points. Labour market flexibility mitigates this: a one-point rise in the flexibility index reduces youth (long-term) unemployment by 0.6-0.7 (1.8-2.2) percentage points., COMPETE; QREN; FEDER; Fundação para a Ciência e a Tecnologia (FCT)

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending cuts seems to be detrimental for income distribution, tax hikes seem to have an equalizing effect. We also show that the size of the fiscal consolidation program (in percentage of GDP) has an impact on income inequality. In particular, when consolidation plans represent a small share of GDP, the income gap widens, suggesting that the burden associated with the effort affects disproportionately households at the bottom of the income distribution. Considering the linkages between banking crises and fiscal consolidation, we find that the effect on the income gap is amplified when fiscal adjustments take place after the resolution of such financial turmoil. Similarly, fiscal consolidation programs combined with inflation are likely to increase inequality and the effects of fiscal adjustments on inequality are amplified during periods of relatively low growth. Our results also provide support for a non-linear relationship between inequality and income and corroborate the idea that trade can promote a more equal distribution of income., COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)

This paper assesses the determinants of the length of fiscal consolidation using annual data for 17 industrial countries over the period 1978-2009. Relying on a narrative approach to identify fiscal consolidation episodes, we show that fiscal variables (such as the budget deficit and the level of public debt) and economic factors (such as the degree of openness, the inflation rate, the interest rate and per capita GDP) are crucial for the fiscal consolidation process. Additionally, we employ duration analysis over a set of consolidation spells and find that, as time goes by, the likelihood of a fiscal consolidation ending is higher. However, the hazard function is not monotonic: indeed, it increases until the eighth or ninth year and starts decreasing afterwards. We also find that: (i) spending-driven consolidations are shorter than tax-driven consolidations; (ii) both types of consolidation are longer in Non-European countries than for European countries; and (iii) the size of the consolidation program (in percentage of GDP) does not significantly affect duration. All in all, our results support the importance of cuts in government spending as a way of bringing economies into a sustainable path for a public debt. Moreover, they highlight the role played by a fiscal framework that imposes discipline in governments as a device of credibly shorten the length of a fiscal consolidation episodes., Fundação para a Ciência e a Tecnologia (FCT)

This paper tests for nonlinear effects of asset prices on the US fiscal policy. By modeling government spending and taxes as time-varying transition probability Markovian processes (TVPMS), we find that taxes significantly adjust in a nonlinear fashion to asset prices. In particular, taxes respond to housing and (to a smaller extent) to stock price changes during normal times. However, at periods characterized by high financial volatility, government taxation only counteracts stock market developments (and not the dynamics of the housing sector). As for government spending, it is neutral vis-a-vis the asset market cycles. We conclude that, correcting the fiscal balance and, notably, the revenue side for time-varying effects of asset prices provides a more accurate assessment of the fiscal stance and its sustainability., Fundação para a Ciência e a Tecnologia (FCT), COMPETE; QREN; FEDER

Prova tipográfica, We assess the response of scal policy to developments in asset markets in the US and the UK. We estimate scal policy rules augmented with aggregate wealth, wealth composition (i.e fi nancial and housing wealth) and asset prices (i.e. stock and housing prices) using: (i) a linear framework based on a fully simultaneous system approach; and (ii) two nonlinear speci cations that rely on a smooth transition regression (STR) and a Markov-switching (MS) model. The linear framework suggests that, while primary spending does not seem to react to wealth composition or asset prices, taxes and primary surplus are signi cantly: (i) cut when fi nancial wealth or stock prices rise; and (ii) raised when housing wealth or housing prices increase. The smooth transition regression model shows that primary spending and scal balance are adjusted in a nonlinear fashion to both wealth and price effects, while the Markov-switching framework highlights the importance of tax cuts (in the US) and spending hikes (in the UK) to offset the decline in wealth during major recessions and nancial crises. Overall, our results provide evidence of a non-stabilizing e¤ect of government debt, a countercyclical policy and a vigilant track of wealth developments by scal authorities., COMPETE;QREN; FEDER;Fundação para a Ciência e a Tecnologia (FCT)

We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spending and revenue – responsiveness and persistence–, a feature not captured by automatic stabilisers, we are able to infer about the sources of fiscal deterioration (improvement). Drawing on quarterly data, we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Square method for eight European Union countries plus the US. The results suggest that significant changes in the fiscal stance (including those related to the current crisis) are reflected in the estimates of persistence and responsiveness., Fundação para a Ciência e a Tecnologia (FCT)

We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. Consequently, the attempts of fiscal policy to mitigate stock price developments (e.g. via taxes on capital gains) may severely de-stabilize housing markets. The empirical findings also point to significant fiscal multiplier effects in the context of severe housing busts, which gives rise to the importance of the implementation of fiscal stimulus packages. In addition, our results suggest that when governments run a budget deficit, they place an upward pressure on real interest rates, which ?crowds-out? private consumption and investment. In contrast, during bust periods, unexpected variation in the fiscal stance ? crowds-in? private spending, which reflects the ?direct? and ?indirect? effects of policy actions? impact arising from a downward movement in real interest rates and an upward revision in price level expectations., Nous étudions le rôle de la politique budgétaire pour expliquer la dynamique des marchés d’actifs. À l’aide d’un modèle de données de panel couvrant une dizaine de pays industrialisés, nous montrons qu’un choc budgétaire positif a un effet négatif sur les prix des actifs boursiers et immobiliers. Les premiers réagissent instantanément au choc et l’effet du choc est temporaire. Les prix des actifs immobiliers réagissent progressivement et l’effet du choc est persistant. Par conséquent, toute tentative de stabilisation des marchés immobiliers à l’aide de la politique budgétaire (par exemple à travers les taxes sur les revenus du capital) peut avoir l’effet opposé à celui recherché en déstabilisant ces marchés. Nous trouvons également des effets multiplicateurs significatifs dans les cas d’éclatement des bulles immobilières, ce qui peut justifier le recours à des plans de stabilisation à partir de l’outil de la fiscalité. Nous mettons également évidence des effets d’éviction des déficits budgétaires sur la consommation et l’investissement (à cause de la pression à la hausse exercée sur les taux d’intérêt)., COMETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT)
