The Economic Impact of the South-North Water Transfer Project in China: A Computable General Equilibrium Analysis

Abstract: Water resources are unevenly spread in China. Especially the basins of the Yellow, Hui and Hai rivers in the North are rather dry. To increase the supply of water in these basins, the South-to-North Water Transfer project (SNWT) was launched. Using a computable general equilibrium model this study estimates the impact of the project on the economy of China and the rest of the world. We contrast three alternative groups of scenarios. All are directly concerned with the South-to-North water transfer project to increase water supply. In the first group of scenarios additional supply implies productivity gains. We call it the "non-market" solution. The second group of scenarios is called "market solution". The market price for water adjusts such that supply and demand are equated again. In the third group of simulations the economic implications of China's capital investment in infrastructure for the water South-North water transfer project is analyzed. Finally, the investment is combined with the increased capacity of water. If an increase in water supply in China leads to an increase in productivity of their water-intensive goods and services (non-market solution) this would result in a huge positive welfare effect from increased production and export. The effect on China's welfare would still be positive, if a market for water would exist (market solution), but the world as a whole would lose. The negative effect for the rest of the world is largely explained by a deterioration of its terms-of-trade. Well functioning water markets in China are unlikely to exist.

Environmental tipping points significantly affect the cost-benefit assessment of climate policies.

Abstract: Most current cost−benefit analyses of climate change policies suggest an optimal global climate policy that is significantly less stringent than the level required to meet the internationally agreed 2 °C target. This is partly because the sum of estimated economic damage of climate change across various sectors, such as energy use and changes in agricultural production, results in only a small economic loss or even a small economic gain in the gross world product under predicted levels of climate change. However, those cost−benefit analyses rarely take account of environmental tipping points leading to abrupt and irreversible impacts on market and nonmarket goods and services, including those provided by the climate and by ecosystems. Here we show that including environmental tipping point impacts in a stochastic dynamic integrated assessment model profoundly alters cost−benefit assessment of global climate policy. The risk of a tipping point, even if it only has nonmarket impacts, could substantially increase the present optimal carbon tax. For example, a risk of only 5% loss in nonmarket goods that occurs with a 5% annual probability at 4 °C increase of the global surface temperature causes an immediate two-thirds increase in optimal carbon tax. If the tipping point also has a 5% impact on market goods, the optimal carbon tax increases by more than a factor of 3. Hence existing cost−benefit assessments of global climate policy may be significantly underestimating the needs for controlling climate change.

Human capital depreciation during hometime

Abstract: We estimate human capital depreciation rates during career interruptions due to family reasons (parental leave and household time) in male- and female-dominated occupations. If human capital depreciation due to family related career breaks is lower in female than in male occupations, this can explain occupational sex segregation because women will take the costs of future breaks into account when optimizing their lifetime earnings. We find that short-run depreciation rates in high-skilled occupations are significantly lower in female than in male occupations. In low-skilled occupations, there is no evidence of this difference. Our findings support the self-selection hypothesis with respect to occupational sex segregation in the more skilled jobs, i.e. high-skilled women might deliberately choose female occupations because of the lower short-term wage penalties for family-related career interruptions.
