The difficult art of eliciting long-run inflation expectations from government bond prices

Central banks are always concerned with keeping long-run inflation expectations well anchored at some implicit or explicit low target inflation rate. To that end, they are constantly on the lookout for indicators that can gauge those expectations accurately. One such indicator frequently reported in the specialized financial press and by central banks around the world is constructed with the forward rates technique, which exploits price differentials between government bonds of various maturities. This article examines the theory behind those indicators and assesses the extent to which they can be trusted in practice.Inflation (Finance) ; Government securities ; Forecasting ; Banks and banking, Central ; Monetary policy ; Interest rates

Argentina's recovery and "excess" capital shallowing of the 1990s

The paper examines Argentina’s economic expansion in the 1990s through the lens of a parsimonious neoclassical growth model. The main finding is that investment remained considerably weaker than what the model would have predicted. The resulting excessive “capital shallowing” could be identified as a weakness of the rapid economic growth of the 1990s that may have played a role in Argentina’s ultimate inability to escape the crisis that started to unfold towards the end of that decade. ; Economic Research Working Paper 0204Capital

Tachinidae (Diptera) del Parque Nacional de La Caldera de Taburiente en La Palma (Islas Canarias)

Data on distribution, abundance and phenology of Tachinidae (Diptera) from the Caldera de Taburiente National Park on La Palma are given, based on systematic Malaise trap and yellow pan trap samples between August 1999 and July 2001. The occurrence of 22 species is proved; all of them were already known from the Canary Islands, but two species (Gonia quadrisetosa and Phytomyptera vaccinii) are recorded from La Palma for the first time. The present paper is a result of the project “Inventory and study of the invertebrate fauna of the Caldera de Taburiente National Park”.Se presentan datos de distribución, abundancia y fenología de Tachinidae (Diptera), obtenidos en el Parque Nacional de la Caldera de Taburiente en La Palma con trampa Malaise y trampa amarilla entre agosto de 1999 y julio de 2001. Han sido recolectadas 22 especies, todas ya conocidas en las Islas Canarias, pero dos especies (Gonia quadrisetosa y Phytomyptera vaccinii) son citas nuevas para La Palma. El presente artículo es un resultado del proyecto “Inventario y estudio de la fauna invertebrada del Parque Nacional de la Caldera de Taburiente”

A new species of genus Pseudaspidapion Wanat, 1990 (Coleoptera, Apionidae) from China

Pseudaspidapion botanicum sp. n. from China is described and figured. Its host plant is Grewia biloba G.Don var. parviflora (Bunge) Hand.-Mazz (Malvaceae: Grewioideae). The genus Harpapion Voss, 1966 is recorded as new for China and Vietnam and two comb. n. are proposed: Harpapion vietnamense (Korotyaev, 1985) (from Aspidapion) and H. coelebs (Korotyaev, 1987) (from Pseudaspidapion). A key to the known species of the genus Pseudaspidapion from China is presented.We thank Marek Wanat for kindly providing us references and many good advices, Boris A. Korotyaev for lending paratypes, Steven R. Davis for doing the linguistic review before submission, Yang Ganyan for collecting specimens, Zhou Dakang for providing information about the host plants, Yin Ziwei and Nico M. Franz for providing the brush-pencil Plug-ins of Adobe Illustrator. We also thank two anonymous reviewers whose suggestions considerably improved our work.

Notas nomenclaturales sobre anfibios actuales y fósiles

A review of extinct and living amphibians known from fossils (Allocaudata, Anura and Caudata) has revealed several cases that require nomenclatural changes in order to stabilize the taxonomy of the group. Nomenclatural changes include homonym replacements, corrections of spelling variants and authorships, name availabilities, and in particular, the proposal of new combinations. These changes will allow the incorporation of some palaeontological taxa to the current evolutionary models of relationship of modern forms based on molecular phylogenies. Rana cadurcorum for Rana plicata Filhol, 1877, Rana auscitana for Rana pygmaea Lartet, 1851, and Rana sendoa for Rana robusta Brunner, 1956. Anchylorana Taylor, 1942 is considered a new synonym of Lithobates Fitzinger, 1843. New combinations proposed are: Anaxyrus defensor for Bufo defensor Meylan, 2005; Anaxyrus hibbardi for Bufo hibbardi Taylor, 1937; Anaxyrus pliocompactilis for Bufo pliocompactilis Wilson, 1968; Anaxyrus repentinus for Bufo repentinus Tihen, 1962; Anaxyrus rexroadensis for Bufo rexroadensis Tihen, 1962; Anaxyrus spongifrons for Bufo spongifrons Tihen, 1962; Anaxyrus suspectus for Bufo suspectus Tihen, 1962; Anaxyrus tiheni for Bufo tiheni Auffenberg, 1957; Anaxyrus valentinensis for Bufo valentinensis Estes et Tihen, 1964; Ichthyosaura wintershofi for Triturus wintershofi Lunau, 1950; Incilius praevius for Bufo praevius Tihen, 1951; Lithobates bucella for Rana bucella Holman, 1965; Lithobates dubitus for Anchylorana dubita Taylor, 1942; Lithobates fayeae for Rana fayeae Taylor, 1942; Lithobates miocenicus for Rana miocenica Holman, 1965; Lithobates moorei for Anchylorana moorei Taylor, 1942; Lithobates parvissimus for Rana parvissima Taylor, 1942; Lithobates rexroadensis for Rana rexroadensis Taylor, 1942; Lithobates robustocondylus for Anchylorana robustocondyla Taylor, 1942; Ommatotriton roehrsi for Triturus roehrsi Herre, 1955; Pelophylax barani for Rana barani Rückert-Ülkumen, 1980; Pelophylax meriani for Rana meriani Meyer, 1853; Pelophylax pueyoi for Rana pueyoi Navás, 1922a; Pelophylax quellenbergi for Rana quellenbergi Navás, 1922; Philoria borealis for Kyarranus borealis Tyler, 1991; Pseudepidalea belogorica for Bufo belogoricus Ratnikov, 1993; Pseudepidalea plana for Bufo planus Ratnikov, 1993; Pseudepidalea prisca for Bufo priscus Spinar, Klembara et Meszáros, 1993, and Pseudepidalea stranensis for Bufo stranensis Nemec, 1972.
