International Interactions

King, Keohane, and Verba (1994, pp. 27-28) argue that we should "maximize the validity of our measurement," "ensure that data-collection methods are reliable," and make all data and analysis replicable. In an effort to improve the measurement of the events data collected by the Intranational Political Interactions (IPI) project, this extension of the project produces two new valid and reliable interval-like scales.

Replication data for: Time Series Intervals and Statistical Inference: The Effects of Temporal Aggregation on Event Data Analysis

While many areas of research in political science draw inferences from temporally aggregated data, rarely have researchers explored how temporal aggregation biases parameter estimates. With some notable exceptions (Freeman 1989, Political Analysis 1:61–98; Alt et al. 2001, Political Analysis 9:21–44; Thomas 2002, "Event Data Analysis and Threats from Temporal Aggregation") political science studies largely ignore how temporal aggregation affects our inferences. This article expands upon others' work on this issue by assessing the effect of temporal aggregation decisions on vector autoregressive (VAR) parameter estimates, significance levels, Granger causality tests, and impulse response functions. While the study is relevant to all fields in political science, the results directly apply to event data studies of conflict and cooperation. The findings imply that political scientists should be wary of the impact that temporal aggregation has on statistical inference

Coding Disaggregated Intrastate Conflict: Machine Processing the Behavior of Substate Actors Over Time and Space.

This article describes a new machine-coded event data set specifically designed to study the spatially, temporally, and tactically disaggregated actions of multiple state and nonstate actors in a systematic fashion. The project develops an extensive set of dictionaries for multiple actors and employs a new coding scheme to organize information on such actors and their behavior. The author describes the machine content-analysis methods used to collect the data and the newly developed coding scheme

Replication data for: "Whither Will they Go? A Global Study of Refugees' Destinations, 1965-1995."

A common public perception in OECD countries suggests that refugees are mostly ‘economic migrants’ in search of a better standard of living. Does the empirical record belie this belief? The authors explore that question within a rationalist approach using aggregate level data that allows them to explore a variety of other co-variates of the choice to seek refuge in one country relative to another. In addition to wages they consider fear of persecution, culture, and the costs of relocation. The results are at odds with the ‘bogus refugees’ image: the effect of average wages is mediated by proximity such that higher average wages are associated with fewer refugees, except among bordering countries. In addition refugees seek asylum in neighboring countries, especially those at war with their own country or those experiencing a civil war. Those who seek refuge in countries other than their neighbors follow colonial tie
