- Abstract:
- The world rice market was aflame last spring and for several months it looked as if the trading edifice that had exhibited such resilience over the last two decades was going to burn to the ground. World prices trebled within less than four months and reached a 30- year inflation-adjusted high. Many market observers thought the previous record set in 1974 would soon be toast. The fire was man-made, not the result of natural developments. While the governments in India, Vietnam, and the Philippines did not to set the world market on fire, that was the unintended result of their actions which threatened both innocent bystanders (low-income rice importers as far away as Africa and Latin America) and, ultimately, poor rice consumers at home. This paper describes what sparked the fire and the accelerants that made a bad situation nearly catastrophic. Fortuitously, when the flames were raging at peak intensity, rain clouds appeared, the winds [market psychology] shifted, and conditions on the ground improved, allowing the fire to die down. It remains to be seen, however, if the trading edifice has been seriously undermined by the actions of decision makers in several key Asian rice exporting and importing countries. In describing the cascading negative effects of these seemingly rational domestic policies, this paper aims to help policy makers in the rice exporting and importing nations to avoid a repeat of the disastrous price spike of 2008.

23. Coping with Rising Food Prices: Policy Dilemmas in the Developing World
- Author:

- Abstract:
- Rising food prices cause considerable policy dilemmas for developing country governments. Letting domestic prices adjust to reflect the full change in international prices generates inflationary pressures and causes severe hardship for poor households lacking access to social safety nets. Alternatively, governments can use food subsidies or export restrictions to stabilize domestic prices, yet this exacerbates global food price increases and undermines a rules-based trading system. The recent episode shows that many countries chose to shift the burden of adjustment back to international markets. The use of corn and oilseed for the production of biofuel will result in a recurrence of such episodes in the foreseeable future.

24. The End of ODA: Death and Rebirth of a Global Public Policy

- Abstract:
- The world of international development assistance is undergoing three concomitant revolutions, which concur to the emergence of a truly global policy. First, it is living through a diversification of the goals it is asked to pursue: to its traditional objective of ushering convergence between less and more developed economies have progressively been adjoined those of financing access to essential services and protecting global public goods. Secondly, faced with this new array of challenges, the world of development aid has demonstrated an impressive capacity to increase the number and diversity of its players, generating a governance conundrum for this eminently fragmented global policy. Thirdly, the instruments used by this expanding array of actors to achieve a broader range of policy objectives have themselves mushroomed, in the wake of innovations in mainstream financial markets. Yet surprisingly, this triple revolution in goals, actors and tools has not yet impacted the way we measure both the financial volumes dedicated to this emerging global policy nor the concrete impacts it aims to achieve. This paper argues for the need to move from the conventional measure of Official Development Assistance to the construction of clearer benchmarks for what ultimately matters: resources and results that concur to 21st century international development.

25. Estimating Fully Observed Recursive Mixed-Process Models with cmp

- Abstract:
- At the heart of many econometric models is a linear function and a normal error. Examples include the classical small-sample linear regression model and the probit, ordered probit, multinomial probit, Tobit, interval regression, and truncated-distribution regression models. Because the normal distribution has a natural multidimensional generalization, such models can be combined into multi-equation systems in which the errors share a multivariate normal distribution. The literature has historically focused on multi-stage procedures for estimating mixed models, which are more efficiently computationally, if less so statistically, than maximum likelihood (ML). But faster computers and simulated likelihood methods such as the Geweke, Hajivassiliou, and Keane (GHK) algorithm for estimating higher-dimensional cumulative normal distributions have made direct ML estimation practical. ML also facilitates a generalization to switching, selection, and other models in which the number and types of equations vary by observation. The Stata module cmp fits Seemingly Unrelated Regressions (SUR) models of this broad family. Its estimator is also consistent for recursive systems in which all endogenous variables appear on the right-hand-sides as observed. If all the equations are structural, then estimation is full-information maximum likelihood (FIML). If only the final stage or stages are, then it is limited-information maximum likelihood (LIML). cmp can mimic a dozen built-in Stata commands and several user-written ones. It is also appropriate for a panoply of models previously hard to estimate. Heteroskedasticity, however, can render it inconsistent. This paper explains the theory and implementation of cmp and of a related Mata function, ghk2(), that implements the GHK algorithm.

26. What Is Poverty Reduction?
- Author:
- Owen Barder
- Publication Date:

- Working Paper
- Institution:
- Center for Global Development
- Abstract:
- There is a healthy debate about how to achieve poverty reduction in developing countries, but not enough discussion of what we mean by “poverty reduction.” “Poverty reduction” is often used as a short-hand for promoting economic growth that will permanently lift as many people as possible over a poverty line. But there are many different objectives that are consistent with “poverty reduction,” and we have to make choices between them. There are trade-offs between tackling current and future poverty, between helping as many poor people as possible and focusing on those in chronic poverty, and between measures that tackle the causes of poverty and those which deal with the symptoms. Because donors focus on just one dimension of poverty reduction (growth) they marginalise other legitimate objectives such as reducing chronic poverty or providing social services in countries that cannot otherwise afford them.

27. Making Markets for Merit Goods: The Political Economy of Antiretrovirals

- Abstract:
- This paper examines the role of policy entrepreneurs and global activists in shaping the international market for antiretroviral drugs to combat HIV/AIDS. When ARVs first came on the market in the 1990s they were exceedingly expensive; the cost of treatment was upwards of $10,000 per year. These drugs were thus accessible only to those patients who had high incomes. But in 2006, the “international community,” meeting at a United Nations General Assembly Special Session (UNGASS), made an astonishing pledge to those who were infected with HIV. It proclaimed that there should be universal access to ARV treatment. This UNGASS, following up on an earlier historic UN special session devoted entirely to AIDS in 2001, marked the first time in history that the international community pledged itself to chronic care for the ill, which in this case includes the approximately 30 million people around the world estimated to be HIV positive. How do we explain the transformation of ARVs from private goods, which only a few could afford, into merit goods that were (at least declaratively) to be made available to everyone? In other words, how does a norm of “universal access to treatment”—that no person should be denied these life-extending drugs—become the ethical basis for global public policy with respect to pharmaceutical allocation? What are the lessons of the ARV story for other global issues? These are the primary questions we explore in this paper. Briefly, we argue that the policy entrepreneurs and activists who promoted the creation of a universal access to treatment regime—of the transformation of ARVs into global merit goods—relied on a combination of moral arguments and ideas with favorable material circumstances. From the ethical perspective, the task of these entrepreneurs was to convince the “international community” that access to ARVs was a “human right,” or conversely to convince decision-makers that it was morally wrong to allocate these life-enhancing drugs solely on the basis of ability to pay. But from a material standpoint, these arguments were greatly facilitated by the lowering prices of ARVs caused by a combination of differential pricing (that is, lower prices for drugs in the developing world than in the advanced welfare states) and competition from generics producers, coupled with increases in foreign aid spending devoted to HIV/AIDS and other diseases.

28. Through the Looking-Glass, and What OLS Found There: On Growth, Foreign Aid, and Reverse Causality

- Abstract:
- The cross-country literature on foreign aid effectiveness has relied on the use of instruments to distinguish causality from mere correlation. This paper uses simple non-instrumental techniques in the spirit of Granger to demonstrate that the main aid-growth connection is a negative causal relationship from growth to aid—aid, that is, as a fraction of recipient GDP. Coarsely, when GDP goes up, aid/GDP goes down. The endogeneity of aid, long-suspected, is real. Less understood is that adding certain common controls to regressions puts this relationship through the looking-glass, flipping both its sign and apparent direction: aid seems to cause growth. Ideally, instrumentation expunges the endogeneity shown here. In practice, estimates of aid's impact have run into problems. Autocorrelation in the errors is widespread, and can render endogenous lagged variables used as regressors or instruments. The pitfalls of “difference” and “system” include invalidity and proliferation of instruments. Multicollinearity in term pairs of interest, such as aid and aid or “project” and “program” aid, can amplify endogeneity bias. The combination of specification problems and widespread fragility (shown in earlier work) leads to pessimism about the ability of cross-country econometrics to demonstrate aid effectiveness. This does not rule an average positive effect, nor does it contradict the fact that aid has saved millions of lives, but it does suggest that the average effect on economic growth is too small to be detected statistically.

29. Prevention Failure: The Ballooning Entitlement Burden of U.S. Global AIDS Treatment Spending and What to Do About It - Working Paper 144

- Abstract:
- U.S. global AIDS spending is helping to prolong the lives of more than a million people and is widely seen as a foreign policy and humanitarian success. Yet this success contains the seeds of a future crisis. Life-long treatment costs are increasing as those on treatment live longer, and the number of new HIV infections continues to outpace the number of people receiving treatment. Escalating treatment costs coupled with neglected prevention measures threaten to squeeze out U.S. spending on other global health needs, even to the point of consuming half of the entire U.S. foreign assistance budget by 2016.

30. Inexcusable Absence: Why 60 Million Girls Still Aren't in School and What to do About It

- Abstract:
- The images of girls returning to school in Afghanistan after the fall of the Taliban drew attention to the lack of educational opportunities for girls all too common in many developing countries. Girls' education is indisputably crucial to development, and the development community has worked hard to get more of them into school. The result: since 1960, there have been remarkable increases in primary school enrollment rates for both boys and girls in developing countries. In most countries, girls' participation has converged with that of boys, bringing gender equity to the educational systems of many poor countries. But the international community has largely overlooked a key issue: that out of the remaining 60 million girls ages 6-11 still not in school, 70 percent belong to socially excluded groups.
