We examine the expectational stability (E-stability) of rational expectations equilibrium in the "New Keynesian" model where monetary policy is optimally derived and interest rate stabilization is added to the central bank's traditional objectives of inflation and output stabilization. We consider both the case where the central bank lacks a commitment technology and the case of full commitment. We show that for both cases, optimal policy rules yield rational expectations equilibria that are E-stable for a wide range of empirically plausible parameter values. These findings stand in contrast to Evans and Honkapohja's findings for optimal monetary policy rules in environments where interest rate stabilization is not a central bank objective. 相似文献

The contribution of natural resources to tax revenues has generally yielded mixed results in the literature. This study asserts that the missing link to explaining these differences is the quality of institutions. More resource revenues reduce tax revenues when institutions are poor. Using an interaction term for natural resources and institutional quality, we show that institutions are decisive for the contribution of natural resources to tax revenue mobilisation. The interaction effect is statistically significant after controlling for per capita gross domestic product (GDP), an alternative measure of quality of institutions and additional regressors. This finding is robust to different econometric specifications and the type of natural resources. 相似文献

This study examines how smoke-free laws influence turnover among restaurant workers. The study uses a unique data set of payroll records of a franchisee of a national full-service restaurant chain operating 23 restaurants in the state of Arizona, a state where several communities have adopted smoke-free laws. Municipal smoke-free laws did not, on average, have a statistically significant effect on the probability of employee separation in the years after implementation. These results suggest that training costs associated with employee turnover would not rise for full-service restaurants in municipalities that adopt smoke-free laws. ( JEL I18, J63) 相似文献

The purpose of this research was to investigate the changes occurring in biscuits under domestic storage conditions. The experimental work involved the storage of manufactured biscuits under closed, open/light and open/dark conditions for appropriate periods of time. Moisture content, texture, colour and peroxide value were determined throughout the storage time. The results indicate that the moisture content of the samples increased under all storage conditions, with a softening of texture. Peroxide values increase with rapid acceleration towards the end of the storage period. Very little change was observed in the colour of the biscuits. 相似文献

The IRR (internal rate of return) and the NPV (net present value) are the two most common and important indicators in investment decisions. These two indicators, however, have intrinsic differences between one another. The IRR is a financial indicator and the NPV an economic indicator of a capital investment. The former gives the private investor's point of view and the latter the society's point of view. The value of ERR varies with the change of Financial arrangement of an investment. The NPV, however, does not but remains constant no matter how the financial arrangement changes. This paper uses an illustrative example to show their intrinsic differences and then describes a mathematical proof to substantiate the different natures of IRR and NPV. 相似文献
