This paper presents some new results on the effects of technology shocks on hours worked based on structural VAR specifications containing various measures of US productivity growth and hours. These specifications can produce different answers depending on which sector of the economy is...

An important trend in macroeconomic research in recent years involves the increased use of optimization-based models with nominal rigidities (such as sticky prices) to analyse how monetary policy affects the economy and how optimal policy should be designed. This paper presents a re-formulated...

Recent years have seen a proliferation in research aimed at assessing monetary policy rules using macroeconomic models built from explicit micro-foundations. In many versions of these models, pricing behaviour is described by a ``new-Keynesian Phillips curve,'' which relates inflation to...

Output per worker can be expressed as a function of technological efficiency and of the capital-output ratio. Because technology is exogenous in the Solow model, all of the endogenous convergence dynamics take place through the adjustment of the capital-output ratio. This paper uses the...

The one-sector Solow-Ramsey model informs how most modern researchers characterize macroeconomic trends and cycles, and evidence supporting the model’s balanced growth predictions is often cited. This paper shows, however, that the inclusion of recent data leads to the balanced growth...

This paper analyzes the stability over time of the econometric process for Euro-area inflation since 1970, focusing in particular on the behaviour of the so-called persistence parameter (the sum of the coefficients on the lagged dependent variables). Perhaps surprisingly, in light of the Lucas...

Unknown-breakpoint tests for possible structural change have become standard in recent years, with the most popular being the so-called Sup-F tests, whose asymptotic distribution was derived by Andrews (1993). We highlight two problems that lead to poor performance when testing for structural...

Using data from the period 1970-1991, Romer and Romer (2000) showed that Federal Reserve forecasts of inflation and output were superior to those provided by commercial forecasters. In this paper, we show that this superior forecasting performance deteriorated after 1991. Over the decade...

Despite the widespread popularity of the Solow growth model, much of the recent empirical work based on the classic framework misrepresents a crucial feature of the model. Namely, the growth rate of technological progress, assumed to be exogenous in the Solow model, is often identified as being...

In 1996, the U.S. Department of Commerce began using a new method to construct all aggregate ``real'' series in the National Income and Product Accounts (NIPA). This method employs the so-called ``ideal chain index'' pioneered by Irving Fisher. The new methodology has some extremely important...
