How Leading International Dairy Companies Adjusted to Changes in World Markets

This Discussion Paper focuses on strategic adjustments made by leading international dairy firms in response to world market developments in the late 1990s and early 2000s. Firms whose strategies were analyzed include Fonterra, Nestle, selected other Western European companies (including the Kerry Group and Parmalat), Kraft Foods, Dairy Farmers of America, and Land O'Lakes. In part, the paper describes dairy industry success stories that have implications for a broader group of dairy companies. It also shows how even successful dairy firms have pursued strategies that expose the companies to significant risks. Strategic alliances entered into by the companies received emphasis in the study.International Dairy Companies, Business Strategies, Agribusiness, Demand and Price Analysis, Financial Economics, Industrial Organization, International Relations/Trade, Marketing, Risk and Uncertainty,

CURRENT ISSUES AFFECTING TRADE AND TRADE POLICY: AN ANNOTATED LITERATURE REVIEW

This review provides a base of literature describing current issues and research on the impacts of lobalization and the industrialization of agriculture and recent approaches to analyze and model agricultural trade and trade policies. Three key factors of the survey are differentiated goods, global economic integration and international supply chain linkages. The review covers 182 publications, which are presented alphabetically by author with a brief annotation describing how it relates to the above criteria. The articles are also indexed by keyword. A brief summary highlights the documented literature and includes a series of issues for future discussion and research.International Relations/Trade,

Measurement of the Nodal Precession of WASP-33 b via Doppler Tomography

We have analyzed new and archival time series spectra taken six years apart during transits of the hot Jupiter WASP-33 b, and spectroscopically resolved the line profile perturbation caused by the Rossiter-McLaughlin effect. The motion of this line profile perturbation is determined by the path of the planet across the stellar disk, which we show to have changed between the two epochs due to nodal precession of the planetary orbit. We measured rates of change of the impact parameter and the sky-projected spin-orbit misalignment of $db/dt=-0.0228_{-0.0018}^{+0.0050}$ yr$^{-1}$ and $d\lambda/dt=-0.487_{-0.076}^{+0.089}$~$^{\circ}$ yr$^{-1}$, respectively, corresponding to a rate of nodal precession of $d\Omega/dt=0.373_{-0.083}^{+0.031}$~$^{\circ}$ yr$^{-1}$. This is only the second measurement of nodal precession for a confirmed exoplanet transiting a single star. Finally, we used the rate of precession to set limits on the stellar gravitational quadrupole moment of $9.4\times10^{-5}<J_2<6.1\times10^{-4}$.Comment: Published in ApJL. 5 pages, 3 figures.

The ethical limits of bungee research in ICTD

Research in ICTD is difficult because engineers with technical expertise are separated from the challenges that they are trying to address by large physical distances and significant social differences. To overcome these challenges, much research involves occasional short visits by external researchers to developing regions to investigate problems and generate ideas which are then developed back at the engineers' home base before further return visits for deployment and evaluation. This paper highlights the ethical limitations of this `bungee research', and reflects on our experiences in evolving more fruitful research practices. We argue that relying on bungee research as a primary model of research engagement is unethical, and we suggest some minimal conditions that are necessary, but not sufficient, for such visits to be ethically defensible in ICTD research

A Survey of Global Impacts of Climate Change: Replication, Survey Methods, and a Statistical Analysis

The present study has two objectives. The first is a review of studies that estimate the global economic impacts of climate change using a systematic research synthesis (SRS). In this review, we attempt to replicate the impact estimates provided by Tol (2009, 2014) and find a large number of errors and estimates that could not be replicated. The study provides revised estimates for a total of 36 usable estimates from 27 studies. A second part of the study performs a statistical analysis. While the different specifications provide alternative estimates of the damage function, there were no large discrepancies among specifications. The preferred regression is the median, quadratic, weighted regression. The data here omit several important potential damages, which we estimate to add 25% to the quantified damages. With this addition, the estimated impact is -2.04 (+ 2.21) % of income at 3 °C warming and -8.06 (+ 2.43) % of income at 6 °C warming. We also considered the likelihood of thresholds or sharp convexities in the damage function and found no evidence from the damage estimates of a sharp discontinuity or high convexity

The Share Economy: A Symposium

In June 1985, the Yale Economics Department sponsored a half-day conference on Martin Weitzman’s striking proposal that sharing would be introduced into compensation arrangements. His suggestions have received wide attention in the popular press and from economists, but the organizers believed that the suggestions were sufficiently novel and promising to warrant careful scrutiny from a wide range of points of view. The conference participants therefore examined the “share economy” from the vantage point of labor economics, capital theory, general equilibrium theory, and macroeconomics
