We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables. The form of model uncertainty our framework encompasses includes : simple...

This paper builds a DSGE model for a SOE in which the central bank systematically intervenes both the domestic currency bond and the FX markets using two policy rules: a Taylor-type rule and a second rule in which the operational target is the rate of nominal currency depreciation. For this, the...

This paper concerns optimal emissions of greenhouse gases when catastrophic consequences are possible. A numerical model is presented which takes into account both continuous climate-feedback damages as well as the possibility of a catastrophic outcome. The uncertainty in the model concerns...

Este artículo propone una nueva aproximación al análisis de las políticas macroprudenciales basado en el bienestar de la economía. En línea con Gerba (2017), fijamos una función de bienestar con criterios de primer y segundo orden ligados a la utilidad agregada de la economía para...

El presente trabajo muestra que los impuestos lineales sobre el consumo son una herramienta potente para lograr una redistribución eficiente. Este es el resultado que se obtiene en un modelo cuantitativo de ciclo de vida que replica la distribución de la renta y de la riqueza en Estados...

In this paper we use a medium-scale DSGE model to quantitatively assess the macroeconomic stabilisation properties of a supranational unemployment insurance scheme. The model is calibrated to the euro area's core and periphery and features a rich fiscal sector, sovereign risk premia and labour...

The purpose of the "counter-cyclical capital buffer" (buffer) is to dampen procyclicality in the financial system, absorb capital losses and prevent a credit crunch during recessions. In this paper, a stylized analytical expression for optimal buffer policy is presented. Results are derived...

Climate change has become one of the most prominent concerns globally. In this paper, we study the transition risk of greenhouse gas emission reduction in structural environmental-macroeconomic DSGE models. First, we analyze the uncertainty in model prediction on the effect of unanticipated and...

This paper studies the macro-financial implications of using carbon prices to achieve ambitious greenhouse gas (GHG) emission reduction targets. My empirical evidence shows a 0.6% output loss and a rise of 0.3% in inflation in response to a 1% shock on carbon policy. Furthermore, I also observe...

This paper studies the role of intangible capital investment in the timing of optimal capital income tax reforms. Within an infinitely lived worker-capitalist model as in Judd (J Public Econ 28:59-83, 1985), we consider two different economies: one in which capitalists devote physical...
