Old problems in the new solutions?
Despite their disappointing performance in the recent past, fertilizer subsidies have re-emerged as a tool in the agricultural strategies of many countries in Sub-Saharan Africa. The new paradigm for fertilizer subsidies calls for use of such mechanisms as vouchers to target benefits to poor smallholders and publicâprivate partnerships to develop private markets. There is some belief that with these innovations, fertilizer subsidy programs will circumvent the deleterious consequences of the programs of the past. However, there has been a glaring lack of innovation in how to prevent politics from dominating the allocation of subsidy program benefits and exacerbating inefficiencies as was the experience in earlier programs. This paper studies how vouchers, which could be used towards the purchase of fertilizer, were distributed amongst districts in Ghanaâs 2008 fertilizer subsidy program. We find that politics played a significant role in the allocation of vouchers. Higher numbers of vouchers were targeted to districts that the ruling party had lost in the previous presidential elections and more so in districts that had been lost by a higher margin. A district received 2 percent more vouchers for each percentage point by which the ruling party had lost the previous presidential election - this amount is both statistically and numerically significant. The analysis also shows that district poverty levels, which should have been an important consideration in an economic efficiency motivated distribution, were not a statistically significant determinant of districtsâ voucher allocation. The evidence that vouchers were targeted to areas in which the opposition party received strong support is suggestive of the vouchers being used for vote-buying. This finding raises the caution that despite innovations in implementing fertilizer subsidies, politically motivated allocation of subsidy benefits remains a major potential source of inefficiency.Fertilizer, politics, Subsidies,
A New Solution of The Cosmological Constant Problems
We extend the usual gravitational action principle by promoting the bare
cosmological constant (CC) from a parameter to a field which can take many
possible values. Variation leads to a new integral constraint equation which
determines the classical value of the effective CC that dominates the wave
function of the universe. In a realistic cosmological model, the expected value
of the effective CC, is calculated from measurable quantities to be O(t_U), as
observed, where t_U is the present age of the universe in Planck units,. Any
application of our model produces a falsifiable prediction for in
terms of other measurable quantities. This leads to a specific falsifiable
prediction for the observed spatial curvature parameter of Omega_k0=-0.0055.
Our testable proposal requires no fine tunings or extra dark-energy fields but
does suggest a new view of time and cosmological evolution.Comment: 5 pages; v3: version accepted by Phys. Rev. Let

New creative careers: the problems of progression and uncertainty
This chapter presents findings from research which we conducted with participants who were current and former art college students, practitioners in different areas of creative arts and design, and therefore workers in a relatively newly named part of the economy, the âcreative industriesâ. Originally identified by New Labour as a significantly successful new sector, they have subsequently received considerable attention from policy-makers and also academic commentators, in the UK and elsewhere. The list of creative industries cited by New Labour (DCMS 2001) also corresponds closely to the subject areas and activities of many art college courses, indicating how these institutions function as a vocational training ground and entry point for the creative industries. In this chapter, we discuss special issues which our research raised in relation to creative working; the implications of our research findings for vocational learners themselves and for course providers, teachers and institutions; sources of advantage and disadvantage for learners, as indicated by our research, and some further implications for those aiming to assist and expand lifelong learning opportunities

The new Basel accord and developing countries: problems and alternatives
The new Basel Accord framework relies on markets and supervisors to discipline banks. Yet both markets and supervisors fail, and more so in developing countries than in high-income countries. Therefore, the new Accord is not, as its designers claim, suitable for wide application. Nevertheless, developing country policymakers have little choice but to implement it in part or in whole. Hence there are problems of governance in international regulation. I offer seven general principles for the design of a prudential regime more robust to government and market failure. Four alternative capital regimes are evaluated in the light of these principles. Simpler and harsher regimes are likely to achieve greater safety with a given level of resources
