Panel data analysis in comparative politics: Linking method to theory

Abstract.  Re-analyzing a study of Garrett and Mitchell ('Globalization, government spending and taxation in the OECD', European Journal of Political Research 39(2) (2001): 145–177), this article addresses four potential sources of problems in panel data analyses with a lagged dependent variable and period and unit dummies (the de facto Beck-Katz standard). These are: absorption of cross-sectional variance by unit dummies, absorption of time-series variance by the lagged dependent variable and period dummies, mis-specification of the lag structure, and neglect of parameter slope heterogeneity. Based on this discussion, we suggest substantial changes of the estimation approach and the estimated model. Employing our preferred methodological stance, we demonstrate that Garrett and Mitchell's findings are not robust. Instead, we show that partisan politics and socioeconomic factors such as aging and unemployment as expected by theorists have a strong impact on the time-series and cross-sectional variance in government spending.     

Addressing Infant and Toddler Issues in the Juvenile Court: Challenges for the 21st Century

To achieve the goal of permanency for children in the child welfare system, it is critical that different disciplines work together, improve communication, and understand each other's role and expertise in the process. Through a case study, this article attempts to show the problems, conflicts, and solutions in working to ensure a child's best interests from three points of view: a children's attorney from New York City, a judge from Miami, Florida, and an infant mental health specialist and interdisciplinary trainer from Los Angeles. First, we propose that emotional caregiving is a fundamental right of all children and includes a stable, nurturing, and permanent long‐term relationship. Conflicts between the timing of children's needs, parents' needs, and the judge's legal duties are discussed as a tension with which we all must struggle to resolve if we are to successfully address children's “irreducible needs” (Brazelton & Greenspan, 2000). If the provision of custodial care shifts toward including emotional care as a goal for the growing number of infants entering the foster care system, the ensuing conflicts will provide opportunities for all parts of the foster care system—including the courts—to rethink how infants' needs are evaluated and factored into decision making.     

CONTINGENCY CONTRACTING WITH JUVENILE OFFENDERS

This study was designed to test whether or not juvenile subjects who were on probation and were under a court order to pay fines would show an increased rate of work when positive contingencies of reinforcement were used in the form of contingency contracts.
