An increase in the availability of emergency contraception (EC) may lead to a decrease in the abortion rate. The 2006 FDA ruling, which relaxed the prescription requirement for EC for women 18 and older, allows us to apply the difference-in-difference methodology on the age-by-year-by-state...

Demand for water will continue to increase as per capita income rises and the population grows, and climate change can exacerbate the problem through changes in precipitation patterns and quantities, evapotranspiration, and land cover—all of which directly or indirectly affect the amount of...

We analyze the forecasting performance of small mixed frequency factor models when the observed variables share stochastic trends. The indicators are observed at various frequencies and are tied together by cointegration so that valuable high frequency information is passed to low frequency...

In many parts of the world, irrigation and groundwater consumption are largely dependent on groundwater. Minimizing the adverse effects of water scarcity requires optimal as well as sustainable groundwater management. A common recommendation is to limit groundwater extraction to maximum...

Richard ButlerÕs tourism area life cycle envisions tourism destinations to evolve in stages from exploration to rapid growth followed by slackening, stagnation, and even decline. The eventual slow-down in tourism growth is attributed to the destinations reaching their physical and social...

Environmentally friendly technologies typically yield social returns far in excess of the private returns to the innovating firm. Governments issue grants to fund such projects in an attempt to increase their supply, but completion is uncertain and many projects never yield a successful...

Existing studies of risk pooling among groups of countries are predicated upon the highly restrictive assumption that all countries have symmetric responses to aggregate shocks. We show that the conventional risk sharing test fails to isolate idiosyncratic fluctuations within countries and...

Sustaining water availability at current prices in the face of growing demand and declining resources is not possible, and scarcity is further exacerbated by falling recharge levels due to climate change, urbanization, and watershed depreciation. We discuss an integrated approach to...

Neoclassical trade theory suggests that factor price convergence should follow increased commercial integration. Rising commercial integration and foreign direct investment followed the 1994 North American Free Trade Agreement between the United States and Mexico. This paper evaluates the degree...

Recovery has begun in the United States and global economies. The US recovery is likely to be anemic by historical standards, raising the possibility that additional stimulus may be desirable. The President and Democrats in Congress have called for a “jobs bill,†and the Federal...
