This paper proposes a new measure of potential output for the USA. The key idea is that potential output is constructed as the level of output which would correspond to a forecast of no inflation change over the policy horizon. The resultant output gap has a clear interpretation as a measure to...

The restriction of exogeneity of certain variables in structural VAR models is rarely tested for consistency with the actual data. The reason is obvious: such a test requires estimates of the structural parameters. This paper proposes a solution for models that assume long-run or contemporaneous...

The purpose of this paper is to estimate the output cost associated with lowering inflation for Australia. The paper is particularly motivated by a strand of theoretical and empirical evidence in the literature suggesting nonlinearity in the output-inflation relationship, namely, a nonlinear...

This paper proposes a method to estimate the NAIRU for the U.S. It shares the notion of Estrella and Mishkin (1999) that defines the NAIRU as a leading indicator of inflation changes over the policy horizon. Our alternative construction offers a more theoretically sound and practically useful...

This article estimates UK core inflation in a structural Vector Autoregression (VAR) framework. While building on the work of Quah and Vahey (1995), we extend their two-variable VAR model to allow for different dynamics depending on the nature of the shocks that potentially influence the process...

In their VAR model, Blanchard and Quah (BQ, 1989) employed uncorrelatedness between Aggregate Supply (AS) and Aggregate Demand (AD) shocks and the long-run output neutrality condition as identifying assumptions. This article conducts a simple Monte Carlo experiment to gauge how well the BQ...

This paper develops a model for optimal capital investment in continuous time when both existing and new capital stocks are subject to uncertainty. The model is generalized to allow for large and infrequent changes in the dynamics of the capital stock, which may arise as a result of natural and...
