Constellations of Fragility : an Empirical Typology of States

2019-06, Ziaja, Sebastian, Grävingholt, Jörn, Kreibaum, Merle

We present a typology of states that distinguishes constellations of state fragility based on empirical patterns. State fragility is here defined as deficiencies in one or more of three core functions of the state. These functions include violence control, implementation capacity, and empirical legitimacy. Violence control refers to the state’s ability to manage the uses of violence within society. Implementation capacity refers to the state’s ability to provide basic public services. Empirical legitimacy refers to the population’s consent to the state’s claim to rule. Employing three to four indicators per dimension for 171 countries over the period 2005–2015 and finite mixture model clustering, we find six dominant constellations that represent different types of state dysfunctionality.

Foreign Aid

2018-04-05, Dreher, Axel, Lang, Valentin F., Ziaja, Sebastian

This chapter reviews the aid effectiveness literature to assess whether foreign aid given to areas of limited statehood (ALS) can be expected to promote economic and social outcomes in the recipient country. It distinguishes between different types of aid, motives for granting it, recipient country policies and characteristics, and the modalities by which aid is delivered, as these factors have been argued to influence its effectiveness. This chapter then compares these properties between recipients most affected by limited statehood and those least affected. This allows us to assess the relative effectiveness of aid in countries with ALS. We conclude that on average aid given there is less likely to be effective than elsewhere. As countries with ALS, however, constitute a heterogeneous group, the specifics of individual countries and the types of aid given matter.


Method Factors in Democracy Indicators

2018-03-19, Elff, Martin, Ziaja, Sebastian

Method factors represent variance common to indicators from the same data source. Detecting method factors can help uncover systematic bias in data sources. This article employs confirmatory factor analysis (CFA) to detect method factors in 23 democracy indicators from four popular data sources: The Economist Intelligence Unit (EIU), Freedom House, Polity IV, and the Varieties of Democracy (V-Dem) project. Using three different multi-dimensional concepts of democracy as starting points, we find strong evidence for method factors in all sources. Method-specific factors are strongest when yearly changes in the scores are assessed. The sources find it easier to agree on long-term average scores. We discuss the implications for applied researchers.
