Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

The monetary economy has properties that cannot be analyzed using the tools of today's dynamic general equilibrium analysis. Keynes's economics, far from being an aberration in the otherwise orderly evolution of modern macroeconomics from Adam Smith's ideas about the invisible hand, was a major...

A view advanced in the aftermath of the late-2000s financial crisis is that lower than optimal interest rates lead to excessive risk taking by financial intermediaries. We evaluate this view in a quantitative dynamic model where interest rate policy affects risk taking by changing the amount of...

This paper analyzes the effects of the implementation of a monetary union on the international transmission of monetary and fiscal policies. A dynamic three-country general equilibrium model, exhibiting monopolistic competition and sticky prices, is used to show how asymmetric monetary and...

The conservative central banker has come under attack recently. Explicitly modeling the interaction of a trade union with monetary policy, it has been argued that the standard solution to the inflationary bias in monetary policy might actually be welfare reducing if the trade union has an...

This paper traces the evolution of debate about the question of Rules versus Discretion in monetary policy from about 1800 until the mid 1930s. Particular attention is paid to long-versus-short-run issues, notably with respect to the 1844 Bank Charter Act, and the Bagehot Principle, as well as...

Realized volatility is a nonparametric ex-post estimate of the return variation. The most obvious realized volatility measure is the sum of finely-sampled squared return realizations over a fixed time interval. In a frictionless market, the estimate achieves consistency for the underlying...

We examine the sources of macroeconomic economic fluctuations by estimating a variety of medium-scale DSGE models within a unified framework that incorporates regime switching both in shock variances and in the inflation target. Our general framework includes a number of different model features...

We develop a set of necessary and sufficient conditions for equilibria to be determinate in a class of forward-looking Markov-switching rational expectations models, and we develop an algorithm to check these conditions in practice. We use three examples, based on the new Keynesian model of...

This paper contributes to the policy evaluation literature by developing new strategies to study alternative policy rules. We compare optimal rules to simple rules within canonical monetary policy models. In our context, an optimal rule represents the solution to an intertemporal optimization...
