We derive new tests for proper calibration of multivariate density forecasts based on Rosenblatt probability integral transforms. These tests have the advantage that they i) do not depend on the ordering of variables in the forecasting model, ii) are applicable to densities of arbitrary...

Since the outbreak of the COVID-19 pandemic, China's mask and vaccine diplomacy have been widely discussed, but the debate relies on a few stylized data points. This article introduces a systematic way to measure China's foreign aid in almost real-time through official customs records of...

The widespread use of foreign aid to address the "root causes" of irregular migration lacks a robust empirical foundation. In a new study (Fuchs, A., A. Groeger, T. Heidland, and L. Wellner (2023). The Effect of Foreign Aid on Migration: Global Micro-Evidence from World Bank Projects. Kiel...

Der weit verbreitete Einsatz von Entwicklungshilfe zur Bekämpfung von "Fluchtursachen" oder, präziser formuliert, irregulärer Migration, entbehrt einer soliden empirischen Grundlage. In einer neuen Studie (Fuchs, A., A. Groeger, T. Heidland, and L. Wellner (2023). The Effect of Foreign Aid on...

In response to surging immigration pressure in Europe and the United States, Western policymakers advocate foreign aid as a means to fight the 'root causes' of irregular migration. This article provides the first global evidence of the effects of aid on migration preferences, migration flows,...

Is political compliance a precondition for healthy trade relations with China? The Chinese government frequently threatens that meetings between its trading partners' officials and the Dalai Lama will be met with animosity and ultimately harm trade ties with China. We run a gravity model of...

We investigate the informal influence of political leaders' spouses on the subnational allocation of foreign aid. Building new worldwide datasets on personal characteristics of political leaders and their spouses as well as on geocoded development aid projects (including new data on 19 Western...

Development assistance has been criticized for a lack of coordination between aid donors. This paper argues that competition for export markets and political support prevents donor countries from closer coordination of aid activities. To test these hypotheses, we perform logit and fractional...
