Models for which the MLE and the conditional MLE coincide 总被引:1,自引:0,他引:1
The MLE, CMLE and MMLE coincide in a linear regression model with fixed individual effects. In this case, there is no incidental parameters problem and the MLE is consistent. The equivalence of these estimators is important because CMLE=MLE implies both the consistency of the MLE and the efficiency of the CMLE. In general, we cannot expect to find a CMLE or MMLE, since there may be no fixed-dimension sufficient statistic for the effects, nor an appropriate transformation of the data whose distribution does not depend on the effects. However, we show that the MLE, CMLE and MMLE do coincide in systems of seemingly unrelated regressions and in systems of simultaneous equations. We establish this result for systems in which (exogenous) variables in addition to (or other than) the intercept may have coefficients which vary over individuals, provided that the set of such variables is the same in every equation.The financial support of the National Science Foundation is gratefully acknowledged. 相似文献

In this paper the contribution of demand and supply shocks of the fluctuation of output and employment is analyzed using quarterly data for four countries (USA, UK, FRG and Switzerland) covering the period 1966 to 1988 in a long run restricted VAR framework for employment, output, the interest rate and inflation. For the USA output and employment fluctuations seem to be dominated by supply shocks in theshort and long run, whereas interest and price level variations are dominated by demand shocks. The result obtained with German and Swiss data are, however, different with two respects: The contribution of demand shocks to output and employment fluctuations are substantial up to a time horizon of eight quarters and price level variations, are at least in the short run, dominated by supply disturbances. Finally, the analysis of the UK data shows the US pattern of results for employment and the price level, but demand shocks are important for output up to four quarters and interest rate movements are dominated by supply shocks. 相似文献

The paper uses cointegration methods to test the market efficiency hypothesis (MEH) in the foreign exchange markets. Four exchange rates are considered-all relative to the US dollar: BP, DM, SF and JY. Survey data on expectations are used to see whether the violation of the MEH is due to expectational errors or risk premia. The results differ for the one-week ahead and the one-month ahead forecasts. With the weekly data we conclude that it is risk premia, and with the monthly data it is both expectational errors and risk premia that account for the violation of the MEH. Given the volatility of the exchange markets, it appears that forecasts over an extended period fail tests of rationality, but one-week ahead forecasts do not fail such tests. 相似文献

The incipient process of intellectualization of global development is described and the role and behavior of intellectual (nonmaterial) services in the world economic relations is presented. Russia’s position on global nonmaterial service markets is analyzed in comparison with other countries. The scope for utilization of the Russian scientific, educational and other intellectual potential in its foreign economic activities is expounded. 相似文献

The present article examines the predictive ability of gender identity congruity in explaining women's responses to advertising appeals. The contributions of the article are twofold: (1) to demonstrate whether advertisements that are congruent with female consumers' gender identities elicit strong positive responses and (2) to identify the factors that moderate/mediate the impact of gender identity congruity on consumer responses to advertisements. The research findings provide evidence of the ability of gender identity congruity to elicit positive responses to advertising appeals. The relationship between gender identity congruity and responses to the advertisement is mediated by advertising involvement. The moderating roles of national culture, physical concern, and physical view are also supported. Overall, the congruity theory provides a powerful framework to examine consumer responses to gender portrayals in advertising. ©2009 Wiley Periodicals, Inc. 相似文献

In an environment in which the primitive is the space of distribution functions, we characterize the quantile functions by the axioms ordinal covariance, monotonicity with respect to first-order stochastic dominance, and upper semicontinuity. We show how to characterize the VaR in a similar manner. 相似文献

Using in-depth interviews of the CEO/Presidents of 21 small manufacturing firms, this research explored how leaders with a high market-oriented cognitive model have intentionally pursued the implementation of that model and how their activities differed from leaders with a low market-oriented cognitive model. Results indicated that leaders in high market-oriented organizations appeared to be working from cognitive models that reflected market-oriented values, and norms consistent with those suggested by Homburg and Pflesser. Additionally, results indicated strong consistencies across firms in the mechanisms used by leaders to implement their high market-oriented cognitive models and different but equally strong consistencies in the mechanisms used by leaders to implement their low market-oriented cognitive models. Structurally, high market-oriented leaders expressed less departmentalization than low market-oriented firms, used some form of internal customer/supplier networks, had very open communication systems, and established performance management systems designed to initiate and reward market-oriented behaviors among employees. 相似文献
