Climate policy negotiations identi ed international technology funding as a means of achieving carbon emissions reductions in developing countries. Such funds are now being realized. This paper is probably the first theory-based discussion of international technology funding. It sets up a Ramsey...

While the worldwide spread of smartphones continues, developing countries have become important markets for these devices. Smartphones' independence of landline networks qualifies them for communication and Internet access in rural areas of developing countries. Drawing upon rural Southeast...

This paper introduces a new trade model type. It combines the gravity model, well-known in international economics, with network theory. With this approach, complicated trade networks can be algebraically solved in form of systems of linear (differential) equations. Business cycles and...

We develop a new concept of rural technology diffusion influenced by labor mobility and business relations. The technology gain effect of labor mobility increases technology diffusiveness, whereas the technology drain effect decreases it. The concept is applied to survey data from the Mekong...

This essay reviews the state of knowledge about the connection of climate change and development aid in a globalizing world and makes three contributions. First, it opts for an integrated treatment of short-term aid, striving for the urgent fulfillment of basic human needs, and long-term aid,...

Besides enabling communication, mobile phones and smartphones support information flows and financial transactions, especially in developing countries, where the coverage of landline networks is limited. Drawing upon new data from rural households in Southeast Asia, this paper shows that mobile...

This paper studies policy instruments that correct insufficient learning-by-doing (LbD) and research and development (R&D) of renewable electricity technologies and insufficient investments in energy efficiency (EE) in the presence of carbon pricing. The theoretical model analysis shows how to...

Klimapolitik wirkt sich auf das Wirtschaftswachstum aus. Laut Modellrechnungen jedoch nur in geringem Maße. Dabei spielt die frühzeitige Verfügbarkeit von Technologien eine wichtige Rolle. Die Auswirkungen klimapolitischer Maßnahmen unterscheiden sich zwischen Industrie- und...

This North-South model of Schumpeterian endogenous growth combines a market, productivity and knowledge effect. A set of various convergent and divergent growth paths is derived that is much richer than in the literature so far. South-North convergence based on North-South technology diffusion...

We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...
