Economic resources are often seen as decisive for the outcomes of military conflicts. This paper asks whether “deeper pockets” help win wars. We construct a fine-grained dataset covering more than 700 interstate disputes and rely on exogenous resource price shocks to estimate the causal...

This paper investigates how an increase in military expenditures affects an economy. It is written in the context of rising geopolitical tensions that have spurred increased military spending in the United States, Europe, and other economic areas. It draws on a large literature in...

Europe needs to take more responsibility for its own security. While EU Member States have made substantial new resources available for European defence, and European defence companies are thriving, more needs to be done. National defence spending will likely continue to rise but there is also...

• By reducing reliance on fossil fuels, EU climate policy substantially lowers Russia's financial strength, thereby limiting its military capabilities to sustain its aggression on Ukraine and beyond. • We provide estimates for the security dividend of EU climate policy. • A one-euro...

Europa muss seine Militärausgaben deutlich erhöhen, aber wie? Diese Frage beantworten wir mit einem Blick in die Geschichte. Wie haben Regierungen in der Vergangenheit in ähnlichen Situationen reagiert? Wie wurden Aufrüstung und Kriege typischerweise finanziert - durch Schulden, Steuern oder...

Europe must rapidly increase its military spending, but how? We collect 150 years of data to study what governments in similar situations have done. How were past military buildups financed? What was the relative importance of debt financing, budget cuts, and taxes? Our main finding is that...

Since Russia's full-scale invasion of Ukraine on 24 February 2022, a process of securitisation of the European Union's (EU) external action can be observed. From an institutional perspective, the Common Foreign and Security Policy (CFSP) increasingly overlaps with the Common Security and Defence...

What determines the effectiveness of military buildups? We introduce the concept of the military multiplier: the percentage increase in military equipment an additional dollar buys. It varies with the costs of allocating resources to military production, depending, among other things, on the...

The article examines the evolution of the current technological paradigm, based on digital technologies, considering the interaction between civilian and military trajectories, with a focus on the US case. Building on an original political economy framework, the activities of corporations and...

Die Koalitionssondierungen haben zu einer Einigung bei der Finanzierung von Infrastruktur und Rüstung geführt. Diese sieht vor, die Schuldengrenze im Grundgesetz bestehen zu lassen und sie zugleich mithilfe von kreditfinanzierten Sondervermögen bzw. Ausnahmeklauseln zu umgehen. Das wirft die...

Europe can no longer rely on the United States for its defence but is currently lacking essential capabilities to assure security itself. European countries should not give up on NATO but seek to close capability gaps by developing the European defence industrial base. The EU can play an...

The design of an operationally and militarily prepared Bundeswehr of the future requires the consideration of multiple facets. Its operation requires reliable access to economic resources (labour, capital, land) and their efficient management. This completely addresses the contradiction between...

Various options are being discussed to increase Germany's defense capabilities. Increasing the size of the Bundeswehr is proving difficult, and compulsory military service hardly seems feasible for economic and socio-political reasons. A European army and technological alternatives such as...

This paper revisits the empirical analysis of Nakamura and Steinsson (2014). I reconstruct and extend the original dataset to cover the period 1966-2019, harmonizing two major sources of data: the Defense Contract Action Data System (DCADS) and USAspending.gov. I discuss how to aggregate these...

Europe has to respond to a new and more contested security order. Russia's imperial ambitions threaten stability and peace, while the United States demands from the European NATO countries to contribute more to their own security. To improve defence capabilities, Europe has to increase defence...

Nach jahrzehntelanger Sicherheit ohne Bedrohung von außen und reduzierten Verteidigungsbudgets wurden die europäischen Länder durch die Invasion Russlands in die Ukraine 2022 zur Neubewertung ihrer geopolitischen Sicherheitslage gezwungen. Dennoch haben einige europäische NATO-Staaten ihre...

Germany needs 782 billion euros in additional public spending for its modernisation by 2030. German politicians have so far lacked a reliable financing framework for this purpose; there are constant discussions around spending cuts or a constitutional reform of the debt brake. Neither strategy...

Die Bundesrepublik steht vor der historischen Aufgabe, inmitten sich überlagernder Krisen und nach langem Modernisierungsstau das zu tun, was nötig ist, um auch in den kommenden Jahren Produktivität, Daseinsvorsorge und Sicherheit zu gewährleisten. Dies erfordert auch einen zielgerichteten...

This study aims to examine the relationship between government spending and economic development in Kenya, given the lack of consensus on the topic globally. While there is an agreement that some level of government expenditure is necessary for economic development, the specific areas of...

Governments often choose deficit financing over budget cuts or tax increases to fund public goods, driven by the political unpopularity of the latter options. This study investigates the potential trade-off between maintaining prudent public finances and securing voter support by analyzing the...

Building a European defence union is at the top of the EU's policy agenda. It is essential to preserving the security and wellbeing of EU society from current and future geopolitical threats. A reflection on the efficiency and quality of defence spending is a crucial first step in this process....

This study addresses the under-researched role of state-owned-enterprises (SOEs) in global value chains/production networks (GVCs/GPNs). It examines how the economic performance, foreign trade, and value capture of Ukrainian firms - classified by ownership, position in GVCs/GPNs, size, and...

China-Russia joint military exercises should be taken seriously, considering their frequency, complexity and global reach. Some are designed for communication and political messaging, signalling displeasure with the US military presence in various regions and defence cooperation among Western...

The EU should expand its support to the development of Ukraine's defence industry to sustain the country's fighting power, reduce its dependencies on Western aid and boost its domestic economy. Two broad areas demand particular attention. As a matter of urgency Ukraine needs investment in local...

The need to reconcile climate and defence priorities is becoming increasingly pressing, especially at a time of significant increases in military activities and expenditure. This has received explicit support from the NATO Secretary General, who, in line with efforts undertaken so far by the EU,...

Undertaking climate action and implementing robust climate risk management in the defence sector has become indispensable. Climate change poses significant risks to the defence workforce, both military and civilian. It threatens infrastructures, assets and capabilities, as well as communities in...
