Sigma-convergence in the OECD: Transitional Dynamics or Narrowing Steady State Differences?
The empirical literature of growth has steadly improved the econometric methods used mainly to address the effect of cross-country heterogeneity in the estimated convergence rate. In this paper, we highlight an important implication of this process of econometric refinement that has so far received little attention. We show that the picture that emerges from models that allow for generalised heterogeneity changes our view of the process of convergence within the OECD. Estimation methods that allow for non or partial heterogeneity stress the importance of transitional dynamics in the process of convergence. Thus sigma-convergence is mostly accounted for by beta-convergence. On the contrary, …
Convergence in the OECD: Transitional Dynamics or Narrowing Steady-State Differences?
I. INTRODUCTION Research on growth and convergence has proceeded through several stages that can be described as a process of accommodating cross-country heterogeneity into the convergence equation. In the first stage, the world could be described as countries approaching to equal (absolute convergence) or to different (conditional convergence) steady states. In both cases--see Baumol (1986) Barro and Sala i Martin (1992), or Mankiw et al. (1992)--the assumption of parameter homogeneity of the underlying production function was assumed and not tested. Later, some researchers (Knight et al. [1993], Islam [1995], Durlauf and Johnson [1995], or Caselli et al. [1996], among others) began to cha…
Macroeconomic performance and convergence in OECD countries
Abstract This paper investigates the robustness of the correlation between growth and a set of variables which comprises accumulation rates in human and physical capital and medium term macroeconomic indicators in OECD countries. We include these variables as additional regressors in the standard growth equation that comes from the human capital-augmented Solow model. Our results show that variables related to medium term macroeconomic performance affect both growth and convergence. In some periods these variables even outperform the explanatory power of the conventional growth variables such as the accumulation rates. Our results also suggest that it is difficult to analyse the contributio…
Structural reforms in a debt overhang
We assess the effects of reforms in product and labor markets in a model economy featuring credit restrictions and pre-existing long-term debt. Both elements, which are core features of the current scenario faced by some euro area countries, combine to produce a slow and protracted deleveraging of the private sector and a persistent recession following a negative financial shock. In this environment, we show that product and labor market reforms may stimulate output and employment even in the short run, despite their defl ationary effects. Furthermore, by favoring a faster recovery of investment and collateral values, product market reforms bring forward the end of deleveraging and the exit…
Households' Balance Sheets and the Effect of Fiscal Policy
En este trabajo identificamos seis tipos de hogares en Estados Unidos en funcion de la composicion de su balance financiero en el Panel Survey of Income Dynamics. Desde 1999 se observa una acusada disminucion en la proporcion de hogares ahorradores y un aumento en la proporcion de hogares endeudados, en particular aquellos que presentan una riqueza neta negativa. Utilizando como marco teorico un modelo neokeynesiano con estos seis tipos de hogares, asi como con imperfecciones en los mercados de credito y de trabajo, exploramos como los cambios en la distribucion de los hogares en funcion de su balance afectan la transmision de los shocks del gasto publico al consumo agregado, al empleo y al…
Debt Sustainability and Fiscal Space in a Heterogeneous Monetary Union: Normal Times Vs the Zero Lower Bound
In this paper we study fiscal policy effects and fiscal space for countries in a monetary union with different levels of public debt. We develop a dynamic stochastic general equilibrium (DSGE) model of a two-country monetary union, calibrated to match the characteristics of Spain and Germany, in which debt sustainability is endogenously determined a la Bi (2012) to shape the responses of the risk premium on public debt. Policy shocks change the market’s expectation about future primary surplus, producing a direct effect on the sovereign risk premium and macroeconomic responses of the economy. In normal times the costs of a government spending driven fiscal consolidation in the high-debt cou…
The Stabilizing Role of Government Size
This paper presents an analysis of how alternative models of the business cycle can replicate the stylized fact that large governments are associated with less volatile economies. Our analysis shows that adding nominal rigidities and costs of capital adjustment to an otherwise standard RBC model can generate a negative correlation between government size and the volatility of output. However, in the model, we find that the stabilizing effect is only due to a composition effect and it is not present when we look at the volatility of private output. Given that empirically we also observe a negative correlation between government size and the volatility of consumption, we modify the model by i…

Implicit Public Debt Thresholds: An Empirical Exercise for the Case of Spain
We extend previous work that combines the Value at Risk approach with estimation of the correlation pattern of the macroeconomic determinants of public debt dynamics by means of Vector Auto Regressions (VARs). These estimated models are used to compute the probability that the public debt ratio exceeds a given threshold, by means of Monte Carlo simulations. We apply this methodology to Spanish data and compute time-series probabilities to analyse the possible correlation with market risk assessment, measured by the spread over the German bond. Taking into account the high correlation between the probability of crossing a pre-specified debt threshold and the spread, we go a step further and …
Intertemporal substitution and the liquidity effect in a sticky price model
Abstract The liquidity effect, defined as a decrease in nominal interest rates in response to a monetary expansion, is a major stylized fact of the business cycle. This paper first confirms that, with separable preferences, a low degree of intertemporal substitution in consumption is a necessary condition for the existence of the liquidity effect. In contrast to this result, in a model with non-separable preferences and capital accumulation it takes an implausibly high elasticity of intertemporal substitution to produce a liquidity effect. The robustness of these results to alternative degrees of nominal rigidities, capital adjustment costs and stochastic monetary processes is also analysed…
Banking Competition, Housing Prices and Macroeconomic Stability
We develop a dynamic general equilibrium model with an imperfectly competitive bank-loans market and collateral constraints that tie investors credit capacity to the value of their real estate holdings. Banks set optimal lending rates taking into account the effects of their price policies on their market share and on the volume of funds demanded by each customer. Lending margins have a significant effect on aggregate variables. Over the long run, fostering banking competition increases total consumption and output by triggering a reallocation of available collateral towards investors. However, as regards the short-run dynamics, we find that most macroeconomic variables are more responsive …
Households' Balance Sheets and the Effect of Fiscal Policy
Using households' balance-sheet composition in the Panel Survey of Income Dynamics, we identify six household types. Since 1999, there has been a decline in the share of patient households and an increase in the share of impatient households with negative wealth. Using a six-agent New Keynesian model with search and matching frictions, we explore how changes in households' shares affect the transmission of government spending shocks. We show that the relative share of households in the left tail of the wealth distribution plays a key role in the aggregate marginal propensity to consume, the magnitude of fiscal multipliers, and the distributional consequences of government spending shocks. W…
Money and the natural rate of interest: structural estimates for the United States and the Euro area
We examine the role of money, allowing for three competing environments: the New Keynesian model with separable utility and static money demand; a non-separable utility variant with habit formation; and a version with adjustment costs for holding real balances. The last two variants imply forward-looking behavior of real money balances, as it is optimal for agents to allow their forecast of future interest rates to affect current portfolio decisions. We distinguish between these specifications by conducting a structural econometric analysis for the U.S. and the euro area. FIML estimates confirm the forward-looking character of money demand. Using these estimates we find that, in response to…
Household Leverage and Fiscal Multipliers
We study the size of fiscal multipliers in response to a government spending shock under different household leverage conditions in a general equilibrium setting with search and matching frictions. We allow for different levels of household indebtedness by changing the intensive margin of borrowing (loan-to-value ratio), as well as the extensive margin, defined as the number of borrowers over total population. The interaction between the consumption decisions of agents with limited access to credit and the process of wage bargaining and vacancy posting delivers two main results: (a) higher initial leverage makes it more likely to find output multipliers higher than one; and (b) a positive g…
Technological differences and convergence in the OECD
Abstract. In this paper we test the homogeneity of the technological parameters among OECD countries, which is the maintained hypothesis in most of the empirical growth literature. We first identify differences in the constant term of the convergence equation estimated for the OECD 1960/1990 sample using a fixed- effects estimator. Then we provide a formal test of the homogeneity of technological parameters across groups of countries. We identify at least two different groups within the OECD, with significantly different technologies. Convergence within each group is fast, supporting the notion of club convergence. Nevertheless, the implausible parameter values obtained for the leading tech…
Household Debt and Fiscal Multipliers
We study the size of government spending multipliers in a general equilibrium model with search and matching frictions in which we allow for different levels of household indebtedness. The main results of the paper are: (a) the presence of impatient households and private debt helps generate government spending multipliers greater than 1; (b) as financial conditions worsen and impatient consumers find it more difficult to borrow (i.e. in a credit crunch), the size of the government spending multiplier falls; (c) conversely, employment, vacancies and unemployment multipliers are larger when access to credit becomes more difficult; and (d) the model explains the observed pattern of responses …
Instruments, rules, and household debt: the effects of fiscal policy
In this paper, we look at the interplay between the level of household leverage in the economy and fiscal policy, the latter characterised by different combinations of instruments and rules. When the fiscal rule is defined on lump-sum transfers, government spending or consumption taxes, the impact multipliers of transitory fiscal shocks become substantially amplified in an environment of easy access to credit by impatient consumers, regardless of the primary instruments used. However, when the government reacts to debt deviations by raising distortionary taxes on income, labour or capital, the effects of household debt on the size of the impact output multipliers vanish or even reverse, no …
Spain in the euro: a general equilibrium analysis
Bayesian dynamic stochastic general equilibrium (DSGE) models combine microeconomic behavioural foundations with a full-system Bayesian likelihood estimation approach using key macro-economic variables. Because of the usefulness of this class ofmodels for addressing questions regarding the impact and consequences of alternative monetary policies they are nowadays widely used for forecasting and policy analysis at central banks and other institutions. In this paper we provide a brief description of the two main aggregate euro area models at the ECB. Both models share a common core but their detailed specification differs reflecting their specific focus and use. The New Area Wide Model (NAWM)…
Household debt and labor market fluctuations
Abstract The co-movements of labor productivity with output, total hours, vacancies and unemployment have changed since the mid 1980s. This paper offers an explanation for the sharp break in the fluctuations of labor market variables based on endogenous labor supply decisions following the mortgage market deregulation. We set up a search model with efficient bargaining and financial frictions, in which impatient borrowers can take an amount of credit that cannot exceed a proportion of the expected value of their real estate holdings. When borrowers' equity requirements are low, the impact of a positive technology shock on the marginal utility of consumption is strengthened, which in turn re…
FISCAL POLICY, MACROECONOMIC STABILITY AND FINITE HORIZONS
In this paper we analyse the stabilisation properties of distortionary taxes in a New Keynesian model with overlapping generations of finitely-lived consumers. In this framework, government debt is part of net wealth and this adds a number of interesting channels through which fiscal policy could affect output and inflation. Output volatility, in presence of technology shocks, is not substantially affected by the operation of automatic stabilisers but we find interesting composition effects. While the presence of finitely-lived households strengthens the stabilisation performance of distortionary taxes through the reduction of the volatility of consumption, it does so at the cost of more vo…
When Fiscal Consolidation Meets Private Deleveraging
We analyze the interaction between fiscal consolidation and private-sector deleveraging in an economy within a monetary union. Pre-existing long term collateralized private debt – a core ingredient of the deleveraging process – plays a critical role in shaping fiscal multipliers. By buffering the short-run fall in debtors’ spending capacity, long-run private debt reduces the short-run multipliers of aggressive (large and/or fast) consolidations. However, absent credibility concerns, aggressive consolidations raise the intensity and length of private deleveraging, causing higher output losses over the medium run. In terms of discounted output losses and welfare, this latter effect dominates,…
The role of the financial system in the growth–inflation link: the OECD experience
Abstract This paper jointly estimates the effects of financial development and inflation on growth using both cross-section and time-series dimensions of the data on inflation, growth, and some banking and stock market indicators over the period 1961–1993 for a sample of OECD countries. Overall, the results indicate, first, that the long-run costs of inflation are not explained by policies of financial repression and, second, that if inflation affects growth through its interaction with financial market conditions, this is not the only (nor the most important) channel.
Deciphering the Macroeconomic Effects of Internal Devaluations in a Monetary Union
We study the macroeconomic effects of internal devaluations undertaken by a periphery of countries belonging to a monetary union. We find that internal devaluations have large and positive output effects in the long run. Through an expectations channel, most of these effects carry over to the short run. Internal devaluations focused on goods markets reforms are generally more powerful in stimulating growth than reforms aimed at moderating wages, but the latter are less deflationary. For a monetary union with a periphery the size of the euro area's, the countries at the periphery benefit from internal devaluations even at the zero lower bound (ZLB) of the nominal interest rate. Nevertheless,…
When fiscal consolidation meets private deleveraging
Abstract Inspired by the recent experience in some euro area countries, we analyze the interaction between fiscal consolidation and private deleveraging in a model of a small open economy in a monetary union. The coexistence of long-term private debt and collateral constraints on new loans implies that, following an adverse financial shock, the economy enters a slow private deleveraging process, the duration of which is endogenous to collateral and debt dynamics. In this context, large and/or front-loaded consolidations increase the length and depth of private deleveraging, causing higher relative output losses over the medium run. As a result, such aggressive consolidation strategies entai…
Sticky-Price Models and the Natural Rate Hypothesis
A major criticism of standard specifications of price adjustment in models for monetary policy analysis is that they violate the natural rate hypothesis by allowing output to differ from potential in steady state. In this paper we estimate a dynamic optimizing business cycle model whose price-setting behavior satisfies the natural rate hypothesis. The price-adjustment specifications we consider are the sticky-information specification of Mankiw and Reis (2002) and the indexed contracts of Christiano, Eichenbaum, and Evans (2005). Our empirical estimates of the real side of the economy are similar whichever price adjustment specification is chosen. Consequently, the alternative model specifi…
Money in an Estimated Business Cycle Model of the Euro Area
We present maximum likelihood estimates of a small scale dynamic general equilibrium model for the Eurozone. We pay special attention to the role of money, both through its direct effect upon private agents’ decisions and as a component of the monetary policy rule. Our results can be summarized as follows. First, we find no direct effect of money upon inflation and output but money growth plays a significant role in the interest rate rule. Second, money demand shocks mainly help to forecast real balances while real shocks explain the bulk of price, output and interest rates fluctuations. Third, the estimated model predicts sensible conditional correlations among those variables both to dema…
Banking Competition, Collateral Constraints and Optimal Monetary Policy
We analyze optimal monetary policy in a model with two distinct financial frictions. First, borrowing is subject to collateral constraints. Second, credit flows are intermediated by monopolistically competitive banks, thus giving rise to endogenous lending spreads. We show that, up to a second order approximation, welfare maximization is equivalent to stabilization of four goals: inflation, output gap, the consumption gap between constrained and unconstrained agents, and the distribution of the collateralizable asset between both groups. Following both financial and non-financial shocks, the optimal monetary policy commitment implies a short-run trade-off between stabilization goals. Such p…
Inflation dynamics in a model with firm entry and (some) heterogeneity
We analyse the incidence of endogenous entry and firm TFP-heterogeneity on the response of aggregate inflation to exogenous shocks. We build up an otherwise standard DSGE model in which the number of firms is endogenously determined and firms differ in their steady state level of productivity. This splits the industry structure into firms of different sizes. Calibrating the different transition rates, across firm sizes and out of the market we reproduce the main features of the distribution of firms in Spain. We then compare the inflation response to technology, interest rate and entry cost shocks, among others. We find that structures in which large (more productive) firms predominate tend…

Automatic stabilizers, fiscal rules and macroeconomic stability
This paper analyzes the effect of the fiscal structure upon the trade-off between inflation and output stabilization in the presence of technological shocks in a DGE model with nominal and real rigidities. The model reproduces the main features of European economies and it integrates a rich menu of fiscal variables as well as a target on the debt to output ratio. The main result of this paper is that distortionary taxes tend to increase output volatility relative to lump-sum taxes unless substantial rigidities are present. We explore in detail the mechanisms that generate such a result, and the conditions under which the supply-side effects of distortionary taxes and the procyclical behavio…
Competition and inflation differentials in EMU
In a monetary union, inflation rate differentials may be substantial over the business cycle. This paper parameterizes a two-country monetary union in which different economic structures in the two countries generate temporary inflation differentials. Cross-country differences are introduced in (i) the elasticity of demand in the goods markets, which cause producers to discriminate prices, (ii) the degree of price inertia and (iii) the degree of openness or preference for foreign goods in consumption. The model is calibrated to reproduce two average large EMU countries and it is able to generate such inflation differentials. We find the mechanism of price discrimination quantitatively more …
BEMOD: A DSGE Model for the Spanish Economy and the Rest of the Euro Area
In this paper we present the theoretical foundations and the simulation results obtained with a new dynamic general equilibrium model developed at the Banco de España for the Spanish economy and the rest of Euro area. The model is designed to help in simulating the effect of alternative shocks on the main aggregate variables. The main contributions of this work from a theoretical perspective are the modelling of a monetary union composed of two regions, the inclusion of housing as a durable good with its own sector of production and the degree and detail of the disaggregation considered for each country in the model, which replicates the Quarterly National Accounts. On the empirical side, t…
Implicit public debt thresholds: An operational proposal
Abstract Gauging the public debt-to-GDP ratio a country can sustain in the medium-run without putting fiscal sustainability at risk is a question of key relevance for policy-makers. Deviations from a safe level of debt should be watched over in order to take corrective measures. In this paper we make a proposal for an operational characterization of the “prudent debt level”. To do so, we use standard methods based on Vector Autoregressions to compute the probability that the public debt ratio exceeds a given threshold, using the Spanish case as an example. The resulting probabilities are highly and positively correlated with market risk assessment, measured by the spread with respect to the…
Growth, inflation and the exchange rate regime
Abstract According to the Balassa-Samuelson effect, growth and inflation are positively correlated in economies with pegged currencies. This paper shows that the costs of inflation on long-term growth are underestimated in samples that include countries and periods with fixed exchange rate regimes.
Market Polarization and the Phillips Curve
The Phillips curve has flattened out over the last decades. We develop a model that rationalizes this phenomenon as a result of the observed increase in polarization in many industries, a process along which a few top firms gain an increasing share of their industry market. In the model, firms compete a la Bertrand and there is exit and endogenous market entry, as well as optimal up and downgrading of technology. Firms with larger market shares find optimal to dampen the response of their price changes, thus cushioning the shocks to their marginal costs through endogenous countercyclical markups. Thus, regardless of its causes (technology, competition, barriers to entry, etc.), the recent i…
Inflation and optimal monetary policy in a model with firm heterogeneity and Bertrand competition
Abstract We study the joint implications of heterogeneity of total factor productivity and strategic price interactions between firms on the dynamics of inflation and the design of optimal monetary policy. In this setting, more productive firms respond less to shocks affecting their marginal costs than less productive firms. As a consequence, economies with a larger proportion of highly productive firms face a flatter Phillips curve. Moreover, when these two features concur, the Ramsey problem gives rise to an optimal non-zero long run inflation that amplifies the differences in relative prices between more efficient and less efficient firms, thus increasing the market share of the former. …
Macroeconomic Modelling in EMU: How Relevant is the Change in Regime?
We analyse the likely effects of changes in the monetary and financial regimes of EMU countries on the dynamics of output and inflation. In particular, we evaluate the impact of the regime shift on the forecasting performance of reduced-form models. Data for both the pre-EMU and the EMU regimes are generated by a relatively standard open-economy-DSGE model with sticky prices and wages and restricted access to financial markets for some individuals. We find that the effects of the shift in the monetary regime on the processes followed by macroeconomic variables depend on the nature of the shocks hitting the economy. For plausible shocks distributions the reduction in the accuracy of VAR-base…
Sticky-price models and the natural rate hypothesis
Abstract A major criticism of standard specifications of price adjustment in models for monetary policy analysis is that they violate the natural rate hypothesis by allowing output to differ from potential in steady state. In this paper we estimate a dynamic optimizing business cycle model whose price-setting behavior satisfies the natural rate hypothesis. The price-adjustment specifications we consider are the sticky-information specification of Mankiw and Reis (Sticky information versus sticky prices: a proposal to replace the new Keynesian Phillips curve. Quarterly Journal of Economics 117, 1295–1328) and the indexed contracts of Christiano et al. (Nominal rigidities and the dynamic effe…
