Connecting private dwellings to the water main is expensive and typically cannot be publicly financed. We show that households’ willingness to pay for a private connection is high when it can be purchased on credit, not because a connection improves health but because it increases the time available for leisure and reduces interand intra-household conflicts on water matters, leading to sustaine...

We explore heat-related labor impacts both for their own interest and to understand the role of adaptation in responding to climate change. Focusing on non-agricultural sectors in the United States, we find that hot temperatures exert a causal negative impact on county-level payroll – reducing payroll by several percentage points in a 2◦C hotter year – with larger impacts in highly exposed indu...

I analyze the effect of inequality on economic growth in Latin America, where inequality is measured as the area of family farms as a percentage of the total area of agricultural holdings. Using data from 18 Latin American countries between 1960 and 2004, I find that inequality has a nonlinear effect on economic growth. Overall, for the countries included in this analysis, the share of family f...

Serological classification of Pseudomonas aeruginosa by the slide agglutination test with live organisms was studied, based on the O antigen schema adopted by the international expert panel sponsored by the Subcommittee on Pseudomonas and Related Organisms of the International Committee on Systematic Bacteriology. The typing results obtained by the slide test with well-absorbed O sera were iden...

In this paper we estimate the effect of agricultural electricity subsidies in India on groundwater extraction and agricultural output. Our empirical approach exploits changes in state electricity prices over time controlling for aggregate annual shocks and fixed district unobservables. Electricity subsidies meaningfully increase groundwater extraction, where the implied extensive margin price e...

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...

Beside the strategies like CBT or Cognitive Behavioral Therapy and psychotherapy art therapy is one of the most important strategies which can help to children with PTSD to cope with this disorder.
