This paper develops a consistent theoretical framework for measuring irrigation water effectiveness and its impact on productivity growth rates by assuming a smooth transition process from traditional to modern irrigation technologies among individual farmers.
In many sectors technological conditions of firm production require the use of specific inputs that are at the same time hazardous for firm workers. Safety rules on the application of these health damaging inputs are not always followed. This in turn implies that firms suffer from important productivity losses due to deterioration of their human capital.
