This statement outlines the objectives and policies of the new journal, Macroeconomic Dynamics, which is dedicated to the advancement of macroeconomics as a science. This Editorial is to appear at the front of the first issue of that journal and is copyright by Cambridge University Press.

Hall (1978) theorized that future consumption could be written only as a function of its current consumption. Since this result is known to be wrong in data, we reexamine, from Flavin's original equations (1981), how they may have reached this conclusion. In the Appendix, we derive a generic...

This paper presents a new approach to assess the role of price mismeasurement in the productivity slowdown. I invert the firm's investment decision to identify the embodied and disembodied components of productivity growth. With a Cobb-Douglas production function, output price mismeasurement...

In spite of elaborate descriptive and correlational studies, the most ubiquitous phenomenon in economics, namely inflation, has remained unexplained in terms of its mathematical origins. Keynes had attempted to relate inflation to a mechanism of "sticky wages and prices". Hitherto, such theories...

Most prices and interest rates display fluctuating levels that embody extractable energy and equivalent amounts of money. Such fluctuations are also associated with varying degrees of uncertainty. Shannon's derivations of spectral entropy and information content offer computational techniques...

Compared to several cross-country studies on the determinants of growth, time series approaches are relatively few and limited in scope. However, time series studies are useful for country-specific policies. But in the recent time series works, with a few exceptions, ad hoc specifications of...

In environments with no commitment and with a need for intertemporal trade, bounded recall is shown to be a sufficient friction for a receipt system (fiat money) to lead to improved allocations in an otherwise frictionless Walrasian model. The absence of other frictions makes price determination...

The large wealth and consumption inequality in the U.S. is usually attributed to two market frictions: debt constraints and incomplete markets. Recent literature has argued that debt constraints are the critical friction while market incompleteness plays only a secondary role. We evaluate the...

This paper derives a model of maintenance expenditures from an analytical framework in which maintenance, utilization and service life are appropriately integrated and estimates it with the help of automobile data from Greece. On the theoretical plain it is shown that the model allows...

The conventional wisdom is that high European unemployment is the result of job markets that are rigid and inflexible. This paper presents new empirical evidence that challenges this received wisdom. A major contribution of the paper is that it fully accounts for both micro- and macroeconomic...
