We explore international variation in business cycle dynamics to gain insights into the recent pattern of robust productivity growth during downturns (productive recessions) and weak employment growth during recoveries (jobless recoveries) seen in some advanced economies. We find that sectoral change is associated with productive recessions but that labor market rigidity can impede reallocation and reduce the probability of a productive recession. We also find evidence of a link between productive recessions and jobless recoveries and that recessions dominated by reductions to employment, rather than changes in average employee hours, are more likely to be associated with jobless recoveries.

Abstract.  Programs that defer taxes on savings (e.g., RRSPs or 401(k)s) are supposed to move income tax systems closer to the more efficient consumption tax. Whether or not RRSPs move income tax systems away from or closer to a consumption tax depends on whether or not interest on debts incurred to make RRSP contributions is deductible for income tax purposes. If people optimize as assumed in simple life‐cycle models, then it may be that governments can convert a non‐linear income tax system to a proportional consumption tax system. I argue this is plausible for some Canadian households. JEL classification: H21, H24  相似文献

The effects of regulation upon technological change in the American meat industry in the period between 1950 and 1978 are examined in terms of the relationship between three alternative models — neoclassical, X-efficiency, and technological exogeneity —and the behavior of regulatory agencies. The paper is based upon patent data, equipment approvals by the United States Department of Agriculture and interviews with meat equipment and meat processing firms. Each theory was found to account for some of the observed transactions between regulation and technological change. Conversely, no single theory encompasses all observed effects.Regulations have added to the cost of developing new products. Increased uncertainty in the late 1970s over the standards sought by regulatory agencies have similarly increased the uncertainties of the profitability of R&D in selected product lines. This uncertainty was also found to be inducing firms to substitute product development via mergers for their own R&D. The Humane Slaughter Act was the proximate spur for technological advances that lead to a rationalization of production processes. The innovations that resulted from this act and from other regulatory standards highlighted, in accordance with the X-efficiency framework, technological opportunities that existed prior to and independent of changes in regulatory standards. Much of the momentum for technological change in the industry was shaped by an initial set of technological advances and the subsequent working through of production bottlenecks in an interrelated production system. These advances were largely independent of and unaffected by regulatory standards.Indeed, there is reason to believe that regulatory standards may themselves have an element of endogeneity in terms of the feasible set of best practice techniques. Thus at any particular time, technological change may serve to generate a production frontier towards which a regulatory agency might seem to propel an industry.Overall, our judgment is that regulation had little discernible impact on the pace of technological change related to the production and distribution of ground beef in the period between 1950 and 1978. If there has been any net effect, regulation probably served more to stimulate than to inhibit technological change.  相似文献

During the Soviet era, directors and workers derived mutual benefits from concealing true capacity, hoarding labour and just fulfilling an enterprise's plan. In an environment of labour shortages and guaranteed markets, managers used informal mechanisms to reward and retain good workers given the absence of unemployment and meaningful wage differentials as mechanisms to discipline workers. This cultivated a paternalistic set of relations between enterprise managers and workers, which, it is argued, are being hollowed out in the post-communist era. This is explored in a case study of evolving labour relations in Moldova. Casualization of the workforce has been used as a buffer against greater instability in both the supply of raw materials and demand. Such a strategy has become feasible as enterprises, such as the case-study firm, now have a large pool of external surplus labour on which they can draw. However, paternalism has not been hollowed out completely but rather a split-level realignment is identified.  相似文献

Almost 1000 adults participated in the development of the Cognitive Style Index (CSI), a new measure designed specifically for use with managerial and professional groups. the objectives of the study were, first, to produce a psychome-trically sound instrument suitable for application in large-scale organizational studies, and second, through its development, to confirm empirically the generic intuition-analysis dimension of cognitive style. Findings suggest that each objective was largely fulfilled. At a time when there is a burgeoning interest in intuition as a basis for decision making and problem solving in organizations, the CSI would appear to be a notable addition to the small collection of measures appropriate for survey research.  相似文献
