U.S. Government Litigation Strategies in the Federal Appellate Courts
federal judicial system.Critical to this influence are the decisions the government makes as to which of the hundreds of possible cases to request a rehearing en banc by a circuit court of appeals, or to appeal to the U.S. Supreme Court
U.S. Government Litigation Strategies in the Federal Appellate Courts
I examine the decisions of the Department of Justice appellate sections and the Office of the Solicitor General to appeal unfavorable U.S. court of appeals decisions to which the federal government is a party during 1993 and 1994. I hypothesize that factors relating to the cost, reviewability and likelihood of victory in the appeal will be influential in the government's decision, and that the influence of each of these types of factors will vary…
Generalized Estimating Equation Models for Correlated Data
Political scientists are often called upon to estimate models in which the standard assumption that the data are conditionally independent can be called into question. I review the method of generalized estimating equations (GEE) for dealing with such correlated data. The GEE approach offers a number of advantages to researchers interested in modeling correlated data, including applicability to data in which the outcome variable takes on a wide r…
Duration Models and Proportional Hazards in Political Science
period. In recent years political scientists have increasingly adopted a wide range of techniques for modeling duration data. But while the use of duration models by political scientists has increased dramatically, a concomitant examination of the modeling assumptions underlying these methods has not accompanied this growth. An important characteristic of most of these models is the assumption that the relative hazards over different covariate va…

Modeling Duration Dependence
As applications of duration analysis have burgeoned in political science, scholars have become increasingly aware of the potential substantive importance of duration dependence: the extent to which the conditional hazards of the events of interest are rising or falling over time. Here I discuss the issue of duration dependence, focusing on the distinction between “spurious” dependence due to unobserved heterogeneity and “true” duration dependence…
Of Time and Consensual Norms in the Supreme Court
Theory: We argue that levels of concurrence and dissent on the U.S. Supreme Court are functions of norms. These norms arise from, and are influenced by, the behaviors of the individual justices, including the actions of the chief justices. In turn, they cause concurrences and dissents to fluctuate around a common level. Hypotheses: If consensual norms are a substantial influence on the behavior of the Court, the long-run extent of concurrence and…
An Analytic and Empirical Examination of Zero-Inflated and Hurdle Poisson Specifications
This article examines two alternative specifications for estimating event-count models in which the data-generating process results in a larger number of zero counts than would be expected under standard distributional assumptions. The author compares King's hurdle event count model and Greene's zero-inflated Poisson model, using data on congressional responses to Supreme Court decisions from 1979 to 1988. The author shows that each of these mode…
The Strategic Timing of Position Taking in Congress
A critical element of decision making is the timing of choices political actors make; often when a decision is made is as critical as the decision itself. We posit a dynamic model of strategic position announcement based on signaling theories of legislative politics. We suggest that members who receive clear signals from constituents, interest groups, and policy leaders will announce their positions earlier. Those with conflicting signals will se…
