While previous research has discussed the effect of interval lengths on congestion control, this paper investigates th...

We address three broad sets of issues: firstly, the effect that immigration has on the host country's labour market.

Wind power is the fastest growing renewable energy source in the United States. Existing empirical studies on the economic impact of wind power development have primarily relied on case studies and input-output models, which have limitations. This study instead uses a linear fixed effects model to estimate the county level effects of wind power in the Great Plains region of the United States fr...

Use of rFVIIa compared to 'usual therapy' is associated with improvements on a number of outcomes, including speed of bleed resolution, duration of pain, and quality of life. The extra costs o...
