This paper investigates methods of assessing dynamic efficiency, points out their shortcomings and develops a new criterion of determining whether or not an economy accumulates too much capital. This criterion is then applied to the OECD countries as well as China. The analysis sheds a new light...

This paper argues that the production constraints in the basic NAIRU model should be distinguished by type: capital constraints and labour constraints. It notes the failure to incorporate this phenomenon in standard macro models. Using panel data for UK manufacturing over 80 quarters we show...

The downturn in fixed investment among advanced economies from the onset of the global crisis was unusually severe, widespread and long-lasting relative to comparable episodes in the past. As a result, investment gaps are large in many countries, not only in relation to past norms but also...

The extent to which domestic and foreign operations of multinational corporations (MNCs) are related has important implications for the analysis of investment demand and its responsiveness to tax policy. We estimate the structural parameters of a model in which domestic and foreign investment...

We develop a theory linking "misallocation," i.e., dispersion in marginal products of capital (MPK), to macroeconomic risk. Dispersion in MPK depends on (i) heterogeneity in firm-level risk premia and (ii) the price of risk, and thus is countercyclical. We document strong empirical support for...

Capital costs are not directly observed since most firms own part of their capital stock. I show how cross-sectional variation in firms' input choices reveals the user cost of capital. Estimating the model using Compustat data, I find that capital costs as a share of output have been declining....
