Annual data for forty-eight states are used to account for changes in the composition of input and output aggregates over space and time, and thereby to obtain new evidence on changes in inputs, outputs, and productivity in U.S. agriculture. The measures change significantly when we use state-specific rather than national prices and when we allow for changes in the composition of the aggregates, especially of labor and capital inputs. We compare our estimates and those reported by Ball et al. ( American Journal of Agricultural Economics 81(1999):164–79). The national estimates are similar but substantial differences are found in state-level productivity growth.  相似文献

This paper investigates the convergence of long‐term ex ante real interest rates (RIRs) obtained from Canadian, French, UK, and U.S. inflation indexed government bonds. In contrast to previous research, our evidence suggests full convergence in the long run and, hence, capital market integration. For the same sample period, global convergence is rejected for RIRs measured in conventional terms. From these results, we conclude that previous tests of the long‐run real interest rate parity might have suffered from weak measurement of real capital market interest rates.  相似文献

在实践中,由于医患双方对医疗侵权诉讼中的举证责任倒置和赔偿范围等问题认识不清,导致医患双方之问的纠纷激增,引发了诸多社会矛盾。本文分析了举证责任倒置的特殊立法成因,指出了立法在加重了医方举证责任的同时,并没有完全免除患方的举证责任。文章最后剖析了医疗侵权损害赔偿的范围问题。  相似文献

How many times is a forecast of a technological development correct? According to many experienced managers, it almost never is. Then what good is a forecast? A forecast helps make important innovation decisions, according to Brian C. Twiss. He argues that precision in forecasting a technological development is seldom needed for purposes of long-term planning and that any innovation so marginal that small errors in forecasting will make a big difference should not be considered anyway. Twiss suggests that technology forecasting can be of real value once it is accepted that it is essentially concerned with modeling human behavior. This is the unexpected viewpoint that Twiss presents in this article. He explains how to develop and how to use a technology forecast in long-range planning.  相似文献

This paper analyzes the money stock effects of the Monetary Control Act (MCA) under a nonborrowed reserve (NBR) operating procedure. Prior to the passage of the MCA, policy was conducted under an interest rate operating target where reserve requirement reforms such as those introduced by the MCA had little influence on money stock variability. Under an NBR procedure however, the structure of reserve requirements may have a significant impact on monetary control. Our analysis indicates that the relative improvement in monetary control greatly depends on the degree of tightness exercised by the Federal Reserve over total reserves in an MCA regime. The tighter the control, the more significant the estimated monetary control benefits of the MCA under an NBR procedure.  相似文献

Criteria for scaling beliefs and evaluations in the Fishbein model are considered, and a procedure is developed and illustrated for the proper test of multiplicative models. Hierarchical regression is shown to be a valid method for testing interaction hypotheses even when measures are only interval or ordinal scaled.  相似文献

A literature on second-best pricing as counterstrategy against monopoly has evolved in economics. The purpose of this paper is to demonstrate that ownership dispersion through forced divestiture can be more effective in restricting the social damage of monopoly. Economists generally hold an ordinal view of utility. To the extent that the second-best literature suggests the possibility of reducing dead-weight loss through counterpricing, most economics would accept counterpricing as welfare increasing and reject ownership dispersion. The example presented in this paper suggests that this mindset may cause us to overlook promising alternatives.  相似文献

This paper examines the usefulness of segmental disclosures required by SFAS No. 14 in assessing the operating risk of the firm. It is shown that the segmental asset data required by SFAS No. 14 is theoretically linked to an assessment of operating risk. In addition, an empirical investigation is conducted to examine whether this new disclosure was material enough to cause a reassessment by market participants of the operating risk of the affected firms. Segmental disclosure policy implications of the findings of this study are also discussed.  相似文献
