The integration of markets may improve efficiency by lowering costs or reducing local market power. India, seeking to reduce electricity shortages, recently set up a market for power trade, in which transmission constraints bind nearly half the time, limiting competition between regions and raising prices by forty percent. I use confidential data on bidding to estimate the costs of electricity ...

In the current age of trade and financial openness, local economies in developing countries are becoming increasingly exposed to external investments. The objective of the proposed two-sector model with environmental externalities is to provide an insight into the interaction between external investors and local communities with a focus upon the different strategies and income sources available...

The literature argues that income growth leads to increased demand for environmental quality and thus reduction in pollution. Using a utility theoretic model, we hypothesize that the income±pollution relationship should depend on the level of disamenity of the pollutant. We proxy for disamenity using the toxicity of releases. For counties in the United States, the functional relationship betwee...

This paper analyzes price elasticities in the Austrian market for mobile telecommunications services using data on firm specific tariffs. Both static and a dynamic panel data approaches lead to consistent results which provide evidence for a relatively elastic demand. Furthermore, some basic facts on the Austrian mobile telephone sector are presented. JEL-Classification: C23, L13, L96.

This papers analyses the causes behind Africa’s unfortunate transformation into the source of the world’s slaves over the early modern period. We discuss the economic and technological forces leading to it, and address questions such as why were most slave buyers Europeans and most slave sellers Africans. We then relate the discussion to the long-term determinants of African underdevelopment, a...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between “dirty” (internal combustion engine) and “clean” (e.g. electric and hybrid) patents across 80 countries over several decades. We show that firms tend to innovate relatively more in clean technologies when they face higher tax-inclusive fuel pr...

This paper reports on my replication of the 1997 Sachs and Warner resource curse working paper. Exact pure replication is achieved. A test for statistical replication shows that some of the Sachs and Warner results attempting to determine the cause of the resource curse are not robust to the country sample. A test for scientific replication shows that findings of the resource curse are not sens...
