Abstract While the effect of risk aversion on farmers' decision-making has long been documented, far less is known about the effect of ambiguity aversion. We argue that ambiguity aversion is just as relevant to their decision-making process because they are uncertain about the yield distributions generated by new technologies. By experimentally measuring risk and ambiguity aversion in rural Peru, we provide new evidence on the role of ambiguity aversion on farm decisions in developing countries: ambiguity aversion, not risk aversion, reduces the likelihood that farmers plant more than one variety of their main crop.

Precautionary Wealth

SummaryThis paper uses microdata from the German Socio-Economic Panel Study (GSOEP) to analyse the importance of precautionary saving under income uncertainty. In a cross-section of households, wealth in 2002 is regressed on alternative measures of income uncertainty. In addition to the usual controls, risk aversion is also taken into account. When using net financial wealth, precautionary saving is statistically significant and economically quite important. Precautionary net financial wealth is estimated to make up, on average, around 20% of total aggregate net financial wealth. Unlike net financial wealth, housing wealth is not used as a buffer stock against income uncertainty, the most likely reason being its illiquidity in Germany. Not controlling for risk aversion leads to an overestimation of precautionary wealth. This result contradicts the findings of Fuchs-Schündeln and Schündeln (2005) who suggest that, owing to self-selection, not controlling for risk aversion results in a significant reduction in aggregate precautionary wealth holdings.

New Evidence

In the late 1980s and early 1990s, many academics, think tank analysts, journalists, and government officials came to perceive India as a de facto nuclear weapons power. The consensus among U.S. policymakers was that normative, rather than technical or organizational hurdles, prevented India from transforming its latent nuclear capability into an operational one. New evidence shows, however, that India lacked technical means to deliver nuclear weapons reliably and safely until 1994–95. Further, until the outbreak of the Kargil War in the summer of 1999, political leaders refrained from embedding the weapons within organizational and procedural routines that would have rendered them operational in the military sense of the term. These deficiencies can be traced to a regime of secrecy that prevented information sharing and coordination among the relevant actors. This secrecy stemmed from risk aversion among Indian decisionmakers, who feared international pressures for nuclear rollback, particularly from the United States.

Right Ascension

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.

Impfungen sind einfache und effektive Maßnahmen zur Verhinderung von Reisekrankheiten. Compliance-Probleme sind gering, da alle Impfungen noch vor Abreise verabreicht werden und bei manchen Impfungen nur eine Dosis für den zuverlässigen Schutz nötig ist. Für jeden Reisenden sind die Hepatitis A- und die Diphtherie-Tetanus-Impfung empfohlen, für Asien und Afrika auch die Polioimpfung. Bei Reisen >30 Tagen, jüngeren Personen und Reisenden mit Risikoverhalten sollte immer auch eine Hepatitis B-Impfung, eventuell als Kombination mit Hepatitis A in Betracht gezogen werden. Je nach Reisestil, -destination und -dauer können auch weitere Impfungen wie z.B. die Typhus-, Tollwut-, Zeckenenzephalitis-, Grippe-, Masern-Mumps-Röteln-, Gelbfieber-, Meningokokkenmeningitis- und die Japanische Enzephalitis-Impfung in Frage kommen. Mehrere Impfungen können gleichzeitig verabreicht werden – eine Staffelung ist nicht nötig. i BAG Supplementum VI, Stand Juli 2000 «Impfungen für Auslandreisende»; http://www.admin.ch/bag/infekt/prev/reisemed/index.htm; Safetravel http://www.safetravel.ch; Tropimed
