We apply a discrete choice approach to model the empirical behaviour of the Federal Reserve in changing the federal funds target rate, the benchmark of short‐term market interest rates in the US. Our methods allow the explanatory variables to be nonstationary as well as stationary. This feature is particularly useful in the present application as many economic fundamentals that are monitored by the Fed and are believed to affect decisions to adjust interest rate targets display some nonstationarity over time. The chosen model successfully predicts the majority of the target rate changes during the time period considered (1994–2001) and helps to explain strings of similar intervention decisions by the Fed. Based on the model‐implied optimal interest rate, our findings suggest that there is a lag in the Fed's reaction to economic shocks during this period.

This paper suggests that the capacity of indigenous groups to engage effectively in a range of planning activities is crucial to achieving land justice and community goals. This argument is relevant in the face of long-standing tensions between indigenous peoples residing in post-settler societies and nation-states such as Australia, Canada, and New Zealand over questions of land and natural resource use. The paper argues that effective planning is crucial for (i) protecting indigenous interests by engaging the planning activities of the state, (ii) the successful acquisition of lands through legal land claim processes, and (iii) helping indigenous communities achieve their goals by implementing effective community-based planning processes.  相似文献

This paper analyzes countertrade as a special case of a customs union in which the countertrade agreement gives rise (as in customs union theory) to both trade-creating and trade-diverting effects. The net effects on welfare are ambiguous. A detailed case study from Egypt and brief examples from other countries illustrate the relevance of this interpretation .  相似文献

The maritime industry provides an interesting case study of the design and implementation of drug-testing programs in the transportation industry during the 1980s. It is clear that such programs were designed and implemented less because of empirical evidence of safety problems than for political reasons. The results in the maritime industry are indicative of a program that is expensive to operate, intrusive with regard to employee privacy, and which will have little or no impact on safety. Focusing such programs on the issue of impairment rather than on the issue of drug usage per se is likely to improve the outcome of the programs. Although, despite common belief, there is little evidence that drug usage or the “drug problem” in U.S. society as a whole had gotten worse in the preceding years (Schonsheck, 1989, 250–251).  相似文献

The idea of judo economics, building on analogies with the sport of judo, has been around for at least 20 years. But taking these ideas further to judo strategy means that a framework of strategic principles can be developed to help companies put stronger opponents on the mat.  相似文献
