The Impact of Fiscal Shocks on the Irish Economy

We study the short-run effects of shocks to government spending on Ireland’s output and its real exchange rate. We show that the impact of government spending shocks critically depend on the nature of the fiscal innovation. Our main finding is that there are important differences between shocks to public investment and shocks to government consumption. Moreover, within the latter category, shocks to the wage and non-wage components also have dissimilar effects.

A Study of the gluon ladder in diffractive processes.

The solution to the non–forward BFKL equation in the Leading Logarithmic approximation is expressed in terms of a sum of iterations of its kernel directly in transverse momentum and rapidity space. Several studies of the non–forward solution are performed both at the level of the gluon Green’s function and for a toy cross–section, including an analysis of the diffusion properties as found in this approach. The method developed in this paper allows for a direct inspection of the momenta in the BFKL ladder, and can be applied to solving the non–forward BFKL equation to next–to–leading logarithmic accuracy, when the corresponding kernel is available

Poor Household Participation in Payments for Environmental Services: Lessons from the Silvopastoral Project in Quindío, Colombia

As the use of Payments for Environmental Services (PES) approaches in developing countries has grown, concern has arisen over the ability of poorer households to participate. This paper uses data from a PES project being implemented in Quindío, Colombia, to examine the extent to which poorer households that are eligible to participate are in fact able to do so. The project provides a strong test of the ability of poorer households to participate in a PES program as it requires participants to make substantial and complex land use changes. The results show that poorer households are in fact able to participate at levels that are broadly similar to those of better-off households. Moreover, their participation was not limited to the simpler, least expensive options. Transaction costs may be greater obstacles to the participation of poorer households than household-specific constraints.Payments for Environmental Services (PES); poverty; silvopastoral; Colombia

Can the Poor Participate in Payments for Environmental Services?: Lessons from the Silvopastoral Project in Nicaragua

This paper uses data from a Payments for Environmental Services (PES) project being implemented in Nicaragua to examine the extent to which poorer households that are eligible to participate are in fact able to do so, an issue over which there has been considerable concern. The study site provides a strong test of the ability of poorer households to participate as it requires participants to make substantial and complex land use changes. The results show that poorer households are in fact able to participate—indeed, by some measures they participated to a greater extent than better-off households. Moreover, their participation was not limited to the simpler, least expensive options. Extremely poor households had a somewhat greater difficulty in participating, but even in their case the difference is solely a relative one. Transaction costs may be greater obstacles to the participation of poorer households than household-specific constraints.Payments for Environmental Services; PES; poverty; participation

Do Concentration Cells Store Charge in Water? Comment on Can Water Store Charge?

In a recent article, Ovchinnikova and Pollack (O&P)(1) reported that the persistent pH gradients (>100 min after electrolysis) generated upon charging a simple electrolytic cell (Pt electrodes in dilute aqueous NaCl solutions) imply that “water can store charge”, in apparent violation of the principle of electroneutrality in bulk macroscopic fluid phases

Fiscal Shocks and The Sectoral Composition of Output

We study the impact of shocks to different types of government spending on the composition of sectoral output for a panel of EMU member countries. We find that fiscal shocks lead to an increase in the relative size of the nontraded sector. There is typically no significant impact on the level of production in the tradables sector but the level of imports increases and the level of exports declines in most cases. Overall, the results show that fiscal shocks matter not only for aggregate variables but also for the sectoral composition of output.

Final states in small x deep inelastic scattering

This talk summarises our work on the calculation of small-$x$ jet rates within the BFKL and CCFM approaches. The two approaches are proven to yield the same results at the leading logarithm level to order ${\bar \alpha}_{S}^{3}$. The proof is then extended to all orders

Solving the BFKL equation in the next-to-leading approximation.

The Balitsky–Fadin–Kuraev–Lipatov equation in the next–to–leading logarithmic approximation is solved using an iterative method. We derive the solution for forward scattering with all conformal spins. A discussion of the infrared finiteness of the results is included
