In the U.K., following the publication of the Radcliffe Report, it was widely believed that monetary policy was impotent because any attempt to make use of monetary policy would be fully offset by perfect money substitutes which were not controlled by the monetary authorities. This paper tests whether such substitutes exist. The technique is to fit a money demand function to a long run of data allowing the interest elasticity to vary from observation to observation, and using a procedure which permits infinite values of the elasticity. It was found that, although the elasticity does vary, no observation was consistent with the Radcliffe view. This was true for both interest rates tried, and the function proved very stable when tested. We conclude that the Radcliffe Hypothesis can be decisively rejected.  相似文献

This paper provides an analysis of how political factors affect the incidence of the evaluation of public policies, with a focus on Randomized Control Trial (RCT) experiments in international development. We argue that political environments where incumbents face greater electoral competition and smaller ruling margins are more likely to host RCT experiments. Using various data sources for the incidence of RCTs both at the cross-country level and at the sub-national level in India, we find that RCTs are more likely to occur in politically competitive jurisdictions. We employ fixed effects regressions using various estimators and an instrumental variable strategy that exploits an electoral reform in India which limited the entry of independent candidates and exogenously affected the degree of electoral competition in state-level politics. The effect seems concentrated on RCTs that have the government as a partner, suggesting that political competition has an important demand-side effect on the incidence of RCTs.  相似文献

This paper assesses the degree of market integration in the U.S. natural gas market following the FERC’s ‘open access’ reforms. Daily spot prices at 76 market locations from 1993 to 1997 are used to examine the geographic extent of the market and the speed with which market forces move prices toward equilibrium in the face of ongoing price shocks. The empirical results suggest that the East and Central regions form a highly integrated market, but that this market is quite segmented from the more loosely integrated Western market.  相似文献

Kaplow (1992) shows in a complete-information environment that allowing income tax deductions for losses as partial insurance is undesirable in the presence of private insurance markets. This paper elaborates on Kaplow's finding by studying two extreme types of asymmetric information structures in private insurance markets: Either the insured or insurers possess superior information. It is shown that our derived result is consistent with Kaplow's if the insured have superior information; however, Kaplow's negative conclusion with respect to the income tax deduction will be overturned if insurers have superior information instead. A policy implication from our finding is that whether or not to allow an income tax deduction for losses needs to be more refined and, specifically, it should be tailored to the “adverse selection” information structures of private insurance.  相似文献

This article investigates the relationship between household income and private transfers received in developing countries. If private transfers are unresponsive to household income, there is less likelihood of expansions in public social security crowding out private transfers. Most literature finds that private transfers are unresponsive, but this may be because responses have been obscured by the methods that ignore nonlinearities. Threshold regression techniques find such nonlinearity in the Philippines and scope for serious crowding out, with 30–80% of private transfers potentially displaced for low-income households (Cox et al., 2004). To see if these nonlinear effects occur more widely, semiparametric and threshold regression methods are used to model private transfers in four developing countries – China, Indonesia, Papua New Guinea and Vietnam. The results reported in this article suggest that nonlinear crowding out effects are not important features of transfer behaviour in these countries. The transfer derivatives under a variety of assumptions only range between 0 and ?0.08.  相似文献

Buying firms are increasingly looking to suppliers for technological innovations that enhance the competitive position of their new products. However, extant research provides limited guidance on how buying firms may gain access to suppliers' innovative technologies. To address this gap in the literature, we draw from social exchange theory to posit sequential relationships among buyer behaviors, preferred customer status, and supplier's willingness to share technological innovations. We test our assertions by applying structural equation modeling statistical analyses to survey response data from 233 sales personnel of production good suppliers in the U.S. automotive industry. Whereas our results show that two buyer behaviors – early supplier involvement and relational reliability – positively affect preferred customer status, a third behavior – share of sales – has no effect. In turn, we find that preferred customer status is positively associated with supplier's willingness to share new technology with the buyer. Further, our findings indicate that preferred customer status fully mediates the benefits exchanged within a buyer–supplier relationship. Hence, our study highlights why buyers seeking innovations should take care that their behavior is appropriate for managing suppliers' perceptions. Accordingly, our results provide specific guidance to buyers as to how they may increase their access to suppliers' new technologies.  相似文献
