Abstract: In the last half-decade, sharp jumps in the prices of wheat, rice, and corn, which furnish about two–thirds of the calorie requirements of mankind, have attracted worldwide attention. These price jumps in grains have also revealed the chaotic state of economic analysis of agricultural commodity markets. Economists and scientists have engaged in a blame game, apportioning percentages of responsibility for the price spikes to bewildering lists of factors, which include a surge in meat consumption, idiosyncratic regional droughts and fires, speculative bubbles, a new “financialization” of grain markets, the slowdown of global agricultural research spending, jumps in costs of energy, and more. Several observers have claimed to identify a “perfect storm” in the grain markets in 2007/2008, a confluence of some of the factors listed above. In fact, the price jumps since 2005 are best explained by the new policies causing a sustained surge in demand for biofuels. The rises in food prices since 2004 have generated huge wealth transfers to global landholders, agricultural input suppliers, and biofuels producers. The losers have been net consumers of food, including large numbers of the world's poorest peoples. The cause of this large global redistribution was no perfect storm. Far from being a natural catastrophe, it was the result of new policies to allow and require increased use of grain and oilseed for production of biofuels. Leading this trend were the wealthy countries, initially misinformed about the true global environmental and distributional implications.

Abstract: Nonlinearities, exponential trends, and Euler equations are three key features of standard dynamic volatility models of speculation, economic growth, or macroeconomic fluctuations with occasionally binding constraints and endogenous state-dependent volatility. A natural way to estimate a model with all such three features could be to use the observed nonstationary data in a single step without preliminary linearization, log-linearization, or preliminary detrending. Adoption of this natural strategy confronts a serious challenge that has been neither articulated nor solved: a dichotomy in the empirical model implied by the Euler equation. This leads to a discontinuity in the regression in the limit, rendering the approaches employed in available proofs of consistency inapplicable. We characterize the problem and develop a novel method of proof of consistency and asymptotic normality. Our methodological contribution establishes a foundation for consistent estimation and hypothesis testing of nonstationary models without resorting to preliminary detrending, an a priori assumption that any trend is exactly zero, linearization, or other restrictions on the model.

Abstract: By including the effects of superstring thresholds, we consider minimal string unification together with the requirement of producing a supersymmetry breaking gluino condensate in the hidden sector. Assigning modular weights to the MSSM fields, consistent with anomaly cancellation, we generate solutions in a class of phenomenologically-viable [Formula: see text] orbifold models. In such models, a hidden photino can be a source of cosmological dark matter.

Abstract: Using the ex le of Merck's donations of ivermectin, to show how tax incentives and non-profit collaborators can make corporate largesse consistent with obligations to maximise returns to shareholders. We obtained information from publicly available data and estimated Merck's tax deductions according to the US Internal Revenue Code. Reviews of Merck-Kitasato contracts and personal interviews provided additional information regarding key lessons from this collaboration. Our best estimate of the direct cost to Merck of the ivermectin tablets donated during 2005-2011 is around US$ 600 million, well below the stated value of US$ 3.8 billion. Our calculation of tax write-offs reduces the net cost to around US$ 180 million in that period. Indirect market benefits and effects on goodwill further enhanced the compatibility of Merck's donation programme with the company's profit-maximising objective. The case offers lessons for effective management of collaborations with public and non-profit organisations. Merck's role in the donation of ivermectin for the treatment of onchocerciasis is widely and justly acknowledged as a prime ex le of corporate largesse in the public interest. It is nevertheless important to note that several public and non-profit collaborators, and United States taxpayers, played significant roles in increasing Merck's incentives, and indeed ability, to conduct the donation programme that changed so many lives in poor countries, while meeting its responsibilities to shareholders. Overall, the record indicates responsible corporate management of Merck's ivermectin programme and demonstrates the feasibility of socially responsible policies in a manner compatible with obligations to shareholders.

Abstract: Song is a learned vocal behavior influenced by social interactions. Prior work has suggested that the anterior forebrain pathway (AFP), a specialized pallial–basal ganglia circuit critical for vocal plasticity, mediates the influence of social signals on song. Here, we investigate the signals the AFP sends to song motor areas and their dependence on social context by characterizing singing-related activity of single neurons in the AFP output nucleus LMAN (lateral magnocellular nucleus of the anterior nidopallium). We show that interaction with females causes marked, real-time changes in firing properties of in idual LMAN neurons. When males sing to females (“directed”), LMAN neurons exhibit reliable firing of single spikes precisely locked to song. In contrast, when males sing alone (“undirected”), the same LMAN neurons exhibit prominent burst firing and trial-by-trial variability. Burst structure and timing vary substantially across repeated undirected trials. Despite context-dependent differences in firing statistics, the average pattern of song-locked firing for an in idual neuron is similar across behavioral contexts, suggesting a common underlying signal. Different LMAN neurons in the same bird, however, exhibit distinct firing patterns, suggesting that subsets of neurons jointly encode song features. Together, our findings demonstrate that behavioral interactions reversibly transform the signaling mode of LMAN neurons. Such changes may contribute to rapid switching of motor activity between variable and precise states. More generally, our results suggest that pallial–basal ganglia circuits contribute to motor learning and production through multiple mechanisms: patterned signals could guide changes in motor output while state-dependent variability could subserve motor exploration.

Abstract: This paper shows that bursts of spikes in the songbird brain during practice carry information about the output motor pattern. The brain’s code for song changes with social context, in performance versus practice. Synergistic combinations of spiking and silence code for time in the bird’s song. This is one of the first uses of information theory to quantify neural information about a motor output. This activity may guide changes to the song.
