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

Abstract The present paper combines loss attitudes and linear utility by providing an axiomatic analysis of corresponding preferences
in a cumulative prospect theory (CPT) framework. In a sense we derive a two-sided variant of Yaari’s dual theory, i.e., nonlinear
probability weights in the presence of linear utility. The first important difference is that utility may have a kink at the
status quo, which allows for the exhibition of loss aversion. Also, we may have different probability weighting functions
for gains than for losses. We apply the model to both portfolio selection and insurance demand. Our results show that CPT
with linear utility has more realistic implications than the dual theory since it implies only a weakened variant of plunging.

Testing measurement invariance using multigroup CFA: differences between educational groups in human values measurement 总被引:1,自引:0,他引:1

This article applies the testing procedures for measurement invariance using multigroup confirmatory factor analysis (MGCFA).
It illustrates these procedures by investigating the factorial structure and invariance of the Portraits Value Questionnaire
(PVQ, Schwartz et al.: J. Cross Cult. Psychol. 32(5), 519–542 (2001)) across three education groups in a population sample (N = 1,677). The PVQ measures 10 basic values that Schwartz postulates to comprehensively describe the human values recognized
in all societies (achievement, hedonism, self-direction, benevolence, conformity, security, stimulation, power, tradition
and universalism). We also estimate and compare the latent means of the three education groups. The analyses show partial
invariance for most of the 10 values and parameters. As expected, the latent means show that less educated respondents attribute
more importance to security, tradition, and conformity values. 相似文献

This paper presents results from a series of experiments designed to test the impact on subject behavior of changes in the risk dominance and payoff dominance characteristics of two player coordination games. The main finding is that changes in risk dominance significantly affect play of the subjects, whereas changes in the level of payoff dominance do not. Observed history of play also has an important influence on subject behavior, both when subjects are randomly rematched after each game and when they remain matched with the same individual for a sequence of games. 相似文献

This paper is a report about the perception of dividends by Chief financial officers (CFOs). The research encompasses five countries, on three continents, and covers three types of economies. Our cross-sectional study is concerned with both inter- and intra-societal differences that may or may not exist regarding the perception of dividends by those who are in charge of making such decisions in the firm. Using a survey instrument, we find that both similarities and dissimilarities exist inter- and intra-culturally. Perhaps the most important conclusion we reach is that dividend research must take a different track than it has been following so far. 相似文献

In order to reduce information asymmetries in relation to a firm's current decisions and long-term strategy, firms must consistently provide information to stakeholders. This paper investigates intellectual capital (IC) information disclosed in mergers and acquisitions (M&A) provided through three different disclosure channels (voluntary press releases, related newspaper articles and subsequent mandatory corporate disclosures in the notes to the financial statements). For a sample of 215 randomly selected US and European M&As, we analyse 215 press releases, 1025 newspaper articles and 215 purchase price allocations. Our findings suggest that IC disclosure in press releases is not perceived as informative and qualitative forward-looking IC information in voluntary corporate disclosures appears to lack credibility. Moreover, we empirically demonstrate interdependencies across the three disclosure channels. The business press seems to filter IC information provided in press releases. The amount of IC disclosure in the notes to the financial statements is positively associated with prior IC disclosure in newspaper articles, but negatively associated with IC disclosure in press releases. The managements of acquirer firms appear to pay attention to news coverage and public opinion. However, both voluntary and mandatory corporate disclosures appear to substitute rather than complement each other. 相似文献
