This paper asks whether tax cycles can represent the optimal policy in a model without any extrinsic uncertainty. I show, in an economy without capital and where labor is the only choicevariable (a Lucas-Stokey economy), that a large class of preferences exists, where cycles are optimal, as well...

This paper estimates the impact on the US economy of four types of uncertainty about (i) government spending, (ii) tax changes, (iii) public debt sustainability and (iv) monetary policy. Following a one standard deviation shock, uncertainty about debt sustainability has the largest and most...

Using a structural VAR analysis, we document that an increase in government purchases raises private consumption, total factor productivity (TFP) and the real wage. This poses a puzzle for both neoclassical and New-Keynesian models. We extend a standard New-Keynesian model to allow for skill...

Brazil has had a long period of high inflation. It peaked around 100 percent per year in 1964, decreased until the first oil shock (1973), but accelerated again afterward, reaching levels above 100 percent on average between 1980 and 1994. This last period coincided with severe balance of...

This paper stresses a new channel through which global financial linkages contribute to the co-movement in economic activity across countries. We show in a two-country setting with borrowing constraints that international credit markets are subject to self-fulfilling variations in the world real...

We exploit a hidden Markov model where inflation is determined by government deficits financed through money creation and/or by destabilizing expectations dynamics (expectations can potentially divorce inflation from fundamentals). The baseline model, proposed by Sargent et al. (2009), is used...

This paper evaluates whether fiscal and foreign exchange policy shocks can explain both credit and credit supply in Venezuela. Empirical evidence suggests that between 65 and 90 percent of credit growth is linked to the buildup of banks' deposits caused by the monetary effects of fiscal...

We examine the conduct of monetary policy in a world where the supply of outside money is controlled by the fiscal authority-a scenario increasingly relevant for many developed economies today. Central bank control over the long-run inflation rate depends on whether fiscal policy is Ricardian or...
