Using Ecological Inference Point Estimates as Dependent Variables in Second-Stage Linear Regressions 总被引:1,自引:0,他引:1
The practice of using point estimates produced by the King ecologicalinference technique as dependent variables in second-stage linearregressions leads to second-stage results that, in general,are inconsistent. This conclusion holds even when all assumptionsbehind King's ecological technique are satisfied. Second-stageinconsistency is a consequence of the fact that King-based pointestimates of disaggregated quantities contain errors correlatedwith the true quantities the estimates measure. Our findingson second-stage inconsistency, as well as a fix that we propose,follow from econometric theory in conjunction with an analysisof simulated and real ecological data sets. 相似文献

We develop an empirical estimator directly from an extensive-formcrisis bargaining game with incomplete information and discussits features and limitations. The estimator makes it possibleto draw inferences about states' payoffs from observationaldata on crisis outcomes while remaining faithful to the theorizedstrategic and informational structure. We compare this estimatorto one based on a symmetric information version of the samegame, using the quantal response equilibrium proposed in thiscontext by Signorino (1999, American Political Science Review93:279298). We then address issues of identificationthat arise in trying to learn about actors' utilities by observingtheir play of a strategic game. In general, a number of identifyingrestrictions are needed in order to pin down the distributionof payoffs and the effects of covariates on those payoffs. 相似文献

This study examined the impact of types of women's verbal refusals, and the timing of her refusal, on men's discrimination of when a female wants her partner to stop making sexual advances. Male students were randomly assigned to 1 of 6 conditions (Explanations × Intimacy Levels). Before listening to an audiotape of a date rape, participants were told they would be listening to an interaction between a man and a woman who had just returned from a date. They were instructed to indicate when the woman wanted the man to stop making sexual advances by pressing a switch that synchronously stopped a timer (yielding the measure of latency). In the vignette, the woman provided an explanation for not engaging in sexual intercourse on the date either during kissing or when the man attempted to touch her breasts. She offered one of three reasons for refusing his sexual advances; fear of pregnancy, waiting until marriage, too early in the relationship. Results revealed an interaction in which participants in the too early in the relationship explanation at the level of breast contact condition displayed significantly longer latencies than individuals in the other groups. The implications of the findings are discussed. 相似文献

The areas of Public Finance and Financial Management present potential problems for small and rural local governments. Responses from a survey of West Virginia local public officials were used to examine the severity of these two issues. Both issues were thought to be of equal importance Instead, the findings showed that Public Finance issues rated very high while Financial Management issues rated very low. Potential influences, such as type of locality, professionalism, and metropolitan area status, fail to explain the differences. Thus, it is concluded that for small and rural localities, Public Finance issues are more important than Financial Management issues 相似文献

This article reports the development and psychometric properties of three standardized and objectively scored measures, the MacArthur Treatment Competence Research Instruments. They were designed to assess abilities related conceptually to four legal standards for competence to consent to treatment: understanding, appreciation, rational manipulation (reasoning), and expressing a choice. Scoring reliability, internal consistency, intertest correlations, and test-retest correlations were examined with data from samples of hospitalized patients with schizophrenia, major depression, and ischemic heart disease, as well as matched non-ill community samples. The results indicate very good interscorer reliability and provide guidance for the use of the instruments and interpretation of their results in future research on patients' decisional abilities in treatment contexts. 相似文献
