Energy security is the ability of households, businesses, and government to accommodate disruptions in supply in energy markets. This survey considers the economic dimensions of energy security, political and other non-economic security concerns and discusses policy approaches that could enhance...

It is well known that the covariance structure of the data alone is not enough to identify an SVAR, and the conventional approach is to impose restrictions on the parameters of the model based on a priori theoretical considerations. This paper suggests that much can be gained by requiring the...

We provide empirical evidence on the dynamics effects of tax liability changes in the United States. We distinguish between surprise and anticipated tax changes using a timing-convention. We document that pre-announced but not yet implemented tax cuts give rise to contractions in output,...

This paper investigates the source of historical fluctuations in annual US data extending back to the late 19th century. Long-run identifying restrictions are used to decompose productivity, hours, and output into technology shocks and non-technology shocks. A variety of models with differing...

This paper studies the state-dependence of the output and welfare effects of shocks to government purchases in a canonical medium scale DSGE model. When monetary policy is characterized by a Taylor rule, the output multiplier (the change in output for a one unit change in government spending) is...

We explore empirically models of aggregate fluctuations with two basic ingredients: agents form anticipations about the future based on noisy sources of information; these anticipations affect spending and output in the short run. Our objective is to separate fluctuations due to actual changes...

More than fifty years ago, Friedman and Schwartz examined historical data for the United States and found evidence of pro-cyclical movements in the money stock, which led corresponding movements in output. We find similar correlations in more recent data; these appear most clearly when Divisia...

When firms face menu costs, the relation between their output and money is highly nonlinear. At the aggregate level, however, this needs not be so. In this paper we study the dynamic behavior of a general equilibrium menu-cost economy where firms are heterogeneous in the shocks they perceive,...

This paper reviews the leading ideas that have emerged within two paradigms of price adjustment. Neither, it appears, provides a satisfactory theoretical scheme when taken in isolation. This paper concludes that an attempt to merge the more convincing elements of each is needed, and some...
