A longstanding puzzle of empirical economics is that average labor productivity declines during recessions and increases during booms. This paper provides a framework to assess the empirical importance of competing hypotheses for explaining the observed procyclicality. For each competing hypothesis we derive the implications for cyclical productivity conditional on expectations of future demand...

In this article the growth models of Feldman (1928) and Mahalanobis (1953) are extended to analyse the implications of the process of structural change on the decisions of investment allocation. By using the device of vertical integration, their constructions are shown to be a particular case of the Pasinetti’s (1981) model of structural change. Their analysis is then carried out in a multi-sec...

A range of parameter changes in I(1) cointegrated time series are not reflected in econometric models thereof, in that many shifts are not easily detected by conventional tests. The breaks in question are changes that leave the unconditional expectations of the I(0) components unaltered. Thus, dynamics, adjustment speeds etc. may alter without detection. However, shifts in long-run means are ge...
