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...

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...

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 sets up a two-period, two-sector trade model of a developing country which is abundant in a natural resource but scarce in industrial goods. It shows that lower future travel costs, rising demand for tourism and higher preferences for the environment slow down today´s depletion of...

This article introduces an innovative and exible dynamic forward calibration method for disaggregated new quantitative trade models, particularly the Eaton and Kortum model, within a computable general equilibrium framework. The model is parameterized based on distinct, consistent future...

This article tries to increase public awareness of a crucial but rarely discussed global challenge by introducing a novel economic analysis: drawing on insights from various disciplines, it studies policies regulating sand extraction and trade. While sand is essential for construction and land...

This article evaluates the recent protectionist US trade policy and the retaliation of the EU and China. The article employs a New Quantitative Trade Theory model and an Armington model for comparison. The simulation results show that US car tariffs are a credible threat to the EU, but the steel...

This article introduces a new Melitz-type model of heterogeneous producers with decreasing returns to scale and different productivities. Different to previous models, it describes smallholder producers in rural areas of developing countries in the context of environment and development...
