Um die Bestimmungsgründe, Ausbreitungsmechanismen und Wirkungen von Umweltinnovationen zu erklären, wurde bisher stark auf einzelnen Fallstudien abgestellt. Um die Forschung auf eine neue und breitere Grundlage zu stellen, führt das ifo Institut derzeit eine Studie zu Entstehung, Diffusion...

Qualitative studies and media reports suggest that the presence of Chinese oil or mining companies generates resentments among local extractive communities due to low wages, poor working conditions, environmental degradation, the employment of foreign labour, and perceived racial discrimination....

This paper proposes a simple framework to better understand an opposition group’s choice between peace, terrorism, and open civil conflict against the government. Our model implies that terrorism emerges if constraints on the ruling executive group are intermediate and rents are sizeable,...

This study employs interactive quantile regressions to assess the conditional role of foreign aid in reducing the potentially negative effect of terrorism on fuel exports in 78 developing countries for the period 1984-2008. Bilateral and multilateral aid indicators are used whereas terrorism...

The sudden rise in land acquisitions in developing countries during the last decade has drawn the attention of scholars and think tanks. A set of recent papers by Deininger (2011), Deininger (2013), and Arezki et al. (2013) sought to understand the empirical determinants of the land rush. They...

This paper provides evidence of the long-run effects of a permanent increase in agricultural productivity on conflict. We construct a newly digitized and geo-referenced dataset of battles in Europe, the Near East and North Africa covering the period between 1400 and 1900 CE. For variation in...

A model of different species competing for the same environment is presented, and possible explanations of peaceful coexistence or rather internecine conflicts are consequently derived. By means of a Lotka-Volterra dynamic system we describe the evolution of two populations (bees and locusts)...

Supply shocks in the global gas market might affect countries differently since the market is regionally interlinked but not perfectly integrated. Additionally, high supply side concentration might expose countries to market power in different ways. To evaluate the strategic position of...

A model of the global gas market is presented which in its basic version optimises the future development of production, transport and storage capacities as well as the actual gas ows around the world assuming perfect competition. Besides the transport of natural gas via pipelines also the...
