The recent surge in studies analyzing spatial dependence in political science has gone hand in hand with increased attention paid to the choice of estimation technique. In comparison, specification choice has been relatively neglected, even though it leads to equally, if not more, serious...

Political units often spatially depend in their policy choices on other units. This also holds in dyadic settings where, as in much of international relations research, the focus of the analysis is the pair or dyad of two political units. Yet, with few exceptions, social scientists have analyzed...

Famine mortality is preventable by government action and yet some famines kill. We develop a political theory of famine mortality based on the selectorate theory of Bueno de Mesquita et al. (2002, 2003). We argue that it can be politically rational for a government, democratic or not, to remain...

The polity2 variable from the Polity IV project is the most popular measure of a country’s political regime. This article contends that the coding rules employed to create a polity2 score during years of so-called interregnum and affected transitions produce a measure of democracy that lacks...

Causal inference seeks to identify a causal mechanism and the set of cases for which the causal claim makes sense. It is always based on a specific sample analyzed. However, whether results can be reliably generalized to the population depends on whether the sample represents a true random draw...

In spatial econometrics, W refers to the matrix that weights the value of the spatially lagged variable of other units. As unimportant as it may appear, W specifies, or at least ought to specify, why and how other units of analysis affect the unit under observation. We show that theory must...

Health policies seek to achieve conflicting objectives. We argue that the objective of saving lives is best served by a careful balancing of fairness and efficiency considerations. Open, fair and equitable access to health care for all citizens will lower overall mortality rates by enabling the...

Terrorism is an instrument for groups that cannot achieve their political goals legally. One important strategic function of terrorism is to weaken the government - either directly by attacking representatives or supporters of the government or indirectly by causing a political response, which...

The article provides a theoretical framework of international unions in the form of a two-stage game with discounting aimed at generating propositions about widening versus deepening in the integration process. Each player has a preference for a set of regulations. Regulatory differences between...

An emerging "clash of civilizations" should reveal itself in patterns of international terror¬ism. Huntington himself explicitly refers to terrorism in the conflict between specific civilizations, and particularly so in the clash between the Islamic civilization and the West. We confront his...
