This paper introduces changes in the level of ambiguity as a complementary source of time-varying risk aversion. We show in a consumption-based asset pricing model with simultaneously risky and ambiguous assets that a rise in the level of ambiguity raises investors' risk aversion. The effect is...

Both from theoretical and practical viewpoints, I argue that the New Keynesian model's forward-looking IS curve should be derived by quadratic approximation. This leaves uncertainty in the basic three-equation model. After adding exogenous AR(1) processes, I examine the results by numerical...

This paper investigates the role of inflation and output uncertainties on monetary policy rules in Turkey for the period 2002 : 01–2014 : 02. In the literature it is suggested that uncertainty is a key element in monetary policy, hence empirical models of monetary policy should regard to...

We solicit household expectations about the economic costs of the COVID-19 pandemic. Households expect output to decrease by about 6 percent and inflation to increase by 5 percentage points in the 12 months following March 2020. We also document that the uncertainty about the overall effect is...

Bauer et al. (2022) derive market-based monetary policy uncertainty and uncover an 'FOMC uncertainty cycle' characterized by a fall of uncertainty after FOMC announcements and its subsequent built-up. Then, the authors show that the financial markets' response to monetary policy announcements...

We build a new empirical model to estimate the global impact of an increase in the volatility of US monetary policy shocks. Specifically, we admit time-varying variances of local structural shocks from a stochastic volatility specification. By allowing for rich dynamic interaction between the...
