Replication data for: Panel Effects in the American National Election Studies

My analyses employing a variety of typical regression models suggest that substantial panel biases are likely to be fairly rare in these data, even when panel and cross-section respondents have markedly different characteristics.

However, two of the dependent variables considered here—campaign interest and turnout—do appear to be sufficiently sensitive to panel effects to warrant significant discounting or adjustment of panel data. I propose adjustments for panel effects in both cross-sectional and dynamic analyses, based upon variants of the "fractional pooling" (Bartels 1996) and "two-stage auxiliary instrumental variables" (Franklin 1990) methods.
