- Abstract
- This paper studies the design of Ramsey optimal monetary policy in a Health New Keynesian (HeNK) model with Susceptible, Infected and Recovered (SIR) agents. The nonlinear model is estimated with maximum likelihood techniques on Euro Area data. Our objective is to deconstruct the mechanism by which contagion risk affects the conduct of monetary policy. If monetary policy is the only game in town, we find that the optimal policy features significant deviations from price stability to mitigate the effect of the pandemic. The best outcome is obtained when the optimal Ramsey policy is combined with a lockdown strategy of medium intensity. In this case, monetary policy can concentrate on its price stabilization objective.

- Abstract
- How does contagion risk affect the business cycle? We find that the presence of contagion risk significantly alters the transmission of standard macroeconomic shocks. Relative to the first-best equilibrium, the contagion externality significantly reduces the response of output to a technology shock. We also argue that the magnitude of the trade-off between health and the economy crucially depends on how the probability of infection is specified. If the probability of infection only depends on agents’ endogenous choices, a weaker trade-off emerges. In such a framework, and relative to the laissez-faire equilibrium, suboptimal policies such as zero COVID strategies, health insurance, or mandatory testing substantially attenuate recessions that are caused by epidemics. Therefore, policies primarily aimed at preserving public health do not necessarily come at the cost of deeper recessions.

- Abstract
- Climate change is one of the most pressing issues of our time. The challenge for policymakers is that climate policies could have a negative impact on the economy in the short term. In this article we discuss how this trade-off between fighting climate change and ensuring a stable business cycle affects the design of environmental policies. We argue in favour of a time-varying carbon tax that is increased during booms and decreased during recessions.

- Abstract
- This paper studies the effects of imperfect risk-sharing between lenders and borrowers on commercial property prices and leverage. The key friction is that agents use different discount rates to evaluate future flows. Eliminating this pecuniary externality generates large reductions in the volatility of real estate prices and credit. Therefore, policies that enhance risk-sharing between lenders and borrowers reduce the magnitude of boom-bust cycles in real estate prices. We also introduce health shocks to study the effect of the COVID-19 crisis on the commercial property market.

- Abstract
- Climate change is one of the greatest economic challenges of our time. Given the scale of the problem, the question of whether a carbon tax should be introduced is hotly-debated in policy circles. This paper studies the design of a carbon tax when environmental factors, such as air carbon-dioxide emissions (CO2), directly affect agents’ marginal utility of consumption. Our first result is that the optimal tax is determined by the shadow price of CO2 emissions. We then use asset-pricing theory to estimate this implicit price in the data and find that the optimal tax is pro-cyclical. It is therefore optimal to use the carbon tax to “cool down” the economy during booms and stimulate it in recessions. The optimal policy not only generates large welfare gains, it also reduces risk premiums and raises the average risk-free real rate. The effect of the tax on asset prices and welfare critically depends on the emission-abatement technology.

- Abstract
- This paper studies the effects of money supply shocks in a general equilibrium model that reproduces a term premium of the magnitude observed in the data. In an environment where financial frictions are the main source of monetary non-neutrality, I find that money supply shocks are less effective at stimulating inflation in recessions than in expansions. In terms of quantitative magnitude, the impact effect on inflation of a money supply shock is about half as large during recessions than during booms. This state dependence is essentially due to the time-variation in stochastic discounting that is needed to match the data.

- Abstract
- This study augments the neoclassical growth model with a mechanism that creates a novel transmission channel through which financial shocks propagate to the real economy. By affecting agents’ ability to finance consumption expenditures, financial frictions create a demand for safe assets that exposes the economy to asset quality shocks. My main finding is that this mechanism provides a potential explanation for the co-movement observed during the 2007-2009 financial crisis in the eurozone. My results also suggest that these shocks are a plausible source of aggregate risk that could explain business cycle fluctuations as well as standard asset pricing puzzles. Finally, introducing this transmission mechanism into the neoclassical growth model increases the welfare cost of business cycle fluctuations by several orders of magnitude.

- Abstract
- This paper studies the cyclical properties of real GDP, house prices, credit, and nominal liquid financial assets in 17 EU countries, by applying several methods to extract cycles. The estimates confirm earlier findings of large medium-term cycles in credit volumes and house prices. GDP appears to be subject to fluctuations at both business-cycle and medium-term frequencies, and GDP fluctuations at medium-term frequencies are strongly correlated with cycles in credit and house prices. Cycles in equity prices and long-term interest rates are considerably shorter than those in credit and house prices and have little in common with the latter. Credit and house price cycles are weakly synchronous across countries and their volatilities vary widely – these differences may be related to the structural properties of housing and mortgage markets. Finally, DSGE models can replicate the volatility of cycles in house and equity prices, but not the persistence of house price cycles.

- Abstract
- Almost two decades after the introduction of the common currency differences in institutional frameworks remain a major source of cross-country heterogeneity in the eurozone. We develop a two-country model with incomplete international markets in which the availability of credit depends on the country’s institutional environment. Our main finding is that structural differences in domestic credit environments provide an explanation for the procyclicality of net capital inflows observed in the South of Europe. We show that frictions in domestic credit markets generate asymmetries in the transmission mechanism of shocks that are common to both regions.

- Abstract
- Although monetary union created the conditions for improving economic and financial integration in the euro area, in the context of the financial and sovereign crises, it has also been accompanied by the emergence of severe imbalances in savings and investment, credit and housing booms in some countries and the allocation of resources towards less productive sectors. The global financial crisis and the euro area sovereign debt crisis then led to major and abrupt adjustments as the risks posed by the large imbalances materialised. Although the institutional shortcomings in the EU that permitted the emergence of imbalances have been largely addressed since 2008, the adjustment process is not yet complete. From a macroeconomic perspective, the imbalances in the external accounts have led to the accumulation of high levels of external liabilities that need to be reduced, which, in turn, is weakening investment and therefore weighing on growth prospects and growth potential. From a macroprudential perspective, the lingering imbalances have added to systemic risk and rendered the euro area more vulnerable to risks. This Occasional Paper analyses the dynamic patterns in macroeconomic imbalances primarily from the former perspective, addressing in particular the connections between macroeconomic and sectoral adjustments of imbalances and the challenges for economic growth and performance over a longer horizon.

- Abstract
- We study the transmission of liquidity shocks in a dynamic general equilibrium model where firms and households are subject to liquidity risk. The provision of liquidity services is undertaken by financial intermediaries that allocate the stock of liquid asset between the different sectors of the economy. We find that the macroeconomic effects of liquidity shocks are considerably larger in the model economy that generates a realistic equity premium. Liquidity constraints amplify business cycle volatility and have nonlinear effects on risk premia. Our empirical analysis suggests that the Great Recession was primarily caused by liquidity factors.

- Abstract
- We develop a representative agent model of a production economy in order to explain the joint dynamics of house prices and equity returns. In a model generating costly business cycle fluctuations, we find that restrictions on housing supply have important implications for asset pricing. Together with habit formation in the composite of consumption and leisure, building restrictions provide an explanation for the high volatility of house prices and contribute to the resolution of asset pricing puzzles.

- Abstract
- We introduce a specification of habit formation featuring non-separability between consumption and leisure into an otherwise standard New Keynesian model. The model can be estimated with standard Bayesian techniques and the bond pricing implications are evaluated using higher-order approximations. The model is able to reproduce a sizeable risk premium on long-term bonds and the cyclicality of fiscal policy has an impact on the bond premium that is quantitatively important. Technology, government spending, and mark-up shocks are the main drivers of the time-variation in bond premia.

- Abstract
- This article studies the asset pricing and the business cycle implications of habit formation in a production economy with capital adjustment costs and endogenous labour supply. A specification of internal habit in the mix of consumption and leisure which minimizes the wealth effect on labour supply is introduced into an otherwise standard real business cycle model. This mechanism enhances the model's ability to explain asset pricing puzzles.
