    Earnings inequality, returns to education and immigration into Ireland
    (Institute for the Study of Labor, 2000-06) ; ;
    Increasing earnings inequality has been an important feature of the US and UK labour markets in recent years. The increase appears to be related to an increased demand for skilled labour and an increase in the returns to education. In this paper we examine what has happened to earnings inequality and the returns to education in Ireland between 1987 and 1997. We find that while both increased between 1987 and 1994, the increases slowed dramatically between 1994 and 1997. This is somewhat surprising as the exceptional growth in the Irish economy occurred from 1994 on. We look to immigration as being a contributing factor to this pattern because a large group of skilled workers flowed into the Irish labour market between 1994 and 1997. We develop a model of the Irish labour market and use it to simulate the impact of an increase in skilled labour. The simulation suggests that immigration did indeed reduce earnings inequality. This result is an interesting corollary to work from the US that shows the immigration of unskilled workers increasing earnings inequality.

    A quantitative analysis of the net benefits of grid integrated wind
    Throughout the world significant development is being encouraged in wind energy for electricity generation. A complete cost and benefit analysis has been conducted in this paper on grid connected wind generation. It takes into account system costs such as reserve requirements, start-up and ramping implications for conventional plants as well as wear and tear costs. The benefits of wind generation analysed include the emissions benefits, the saving on the fuel bill, the electricity generated and the capacity value. These costs and benefits are then used to generate net benefit curves for wind generation and the sensitivities of the curves are tested with changes in the underlying assumptions. A complete unit commitment model with wind generation is used to determine the dispatches upon which the costs and benefits are calculated.
