This analysis examines the validity of utilizing a subset of reduced form equations, such as from a VAR model, for the construction of counterfactual policy analyses. It is shown that the omission of one of the estimated reduced form (VAR) equations and the substitution of a counterfactual policy rule to complete the model severely limits the admissible structure of the economic model that could have generated the historical data.  相似文献

We evaluate and summarize the large body of audit fee research and use meta‐analysis to test the combined effect of the most commonly used independent variables. The perspective provided by the meta‐analysis allows us to reconsider the anomalies, mixed results, and gaps in audit fee research. We find that, although many independent variables have consistent results, several show no clear pattern to the results and others only show significant results in certain periods or particular countries. These variables include a loss by the client and leverage, which have become significant in comparatively recent studies; internal auditing and governance, both of which have mixed results; auditor specialization, regarding which there is still some uncertainty; and the audit opinion, which was a significant variable before 1990 but not in more recent studies.  相似文献

Research institutions in Ghana are facing various challenges. It is the contention that viable research and development institutions are needed for achieving sustainable change in areas of national importance. A key aspect of institutional viability is strong performance management. This implies clear and workable approaches to performance measurement. This paper looks at the initial experiences in a collaborative effort to develop a performance measurement framework for the Food Research Institute (FRI) and the application of the Balanced Score Card (BSC) at institutional level. The process of diagnosing and analysing institutional monitoring and evaluation capacity and systems is described using a mix of diagnostic tools. Stages in applying the BSC approach are documented and the added value of the scorecard perspectives in highlighting focal areas for performance measurement and management within FRI. These are placed in the context of ongoing changes in the external environment posing both threats and opportunities. Changes implied by the introduction of the concept are discussed in the context of current constraints and the way forward is mapped out in terms of enhancing FRIs' impact orientation through the application of improved performance measurement and management.  相似文献

一、引言“全球化”这一说法是最近才开始流行的,而我们这些贸易经济学家对它的研究历史却有几十年甚至上百年了;世界贸易组织(WTO)也是最近才成立的,而国际贸易方面的法律专家对它和它的前身--GATT的研究也已近五十年了。在前面的两种情况中,国际贸易方面的专家都会强调世界经  相似文献

We develop a methodology to estimate the shadow risk free rate or expected intertemporal marginal rate of substitution, “EMRS”. Our technique relies upon exploiting idiosyncratic risk, since theory dictates that idiosyncratic shocks earn the EMRS. We apply our methodology to recent monthly and daily data sets for the New York and Toronto Stock Exchanges. We estimate EMRS with precision and considerable time-series volatility, subject to an identification assumption. Both markets seem to be internally integrated; different assets traded on a given market share the same EMRS. We reject integration between the stock markets, and between stock and money markets.  相似文献
