Openness and optimal monetary policy

We show that the composition of imports has important implications for the optimal volatility of the exchange rate. Using input-output data for 25 countries we document substantial differences in the import and non-tradable content of final demand components, and in the role played by imported inputs in domestic production. We build a business cycle model of a small open economy to discuss how the problem of the optimizing policy-maker changes endogenously as the composition of imports and of final demand is altered. Contrary to models where steady state trade openness is entirely characterized by home bias, we find that trade openness is a very poor proxy of the welfare impact of alternative monetary policies. Finally, we quantify the loss from an exchange rate peg relative to the Ramsey policy conditional on the composition of imports, using parameter values that are estimated from OECD input-output tables data. We find that the main determinant of the losses is the share of non-traded goods in final demand.

Monetary policy, expected inflation and inflation risk premia

Within a New Keynesian business cycle model, we study variables that are normally unobservable but are very important for the conduct of monetary policy, namely expected inflation and inflation risk premia. We solve the model using a third-order approximation that allows us to study time-varying risk premia. Our model is consistent with rejection of the expectations hypothesis and the business-cycle behaviour of nominal interest rates in US data. We find that inflation risk premia are very small and display little volatility. Hence, monetary policy authorities can use the difference between nominal and real interest rates from index-linked bonds as a proxy for inflation expectations. Moreover, for short maturities current inflation is a good predictor of inflation risk premia. We also find that short-term real interest rates and expected inflation are significantly negatively correlated and that short-term real interest rates display greater volatility than expected inflation. These results are consistent with empirical studies that use survey data and index-linked bonds to obtain measures of expected inflation and real interest rates. Finally, we show that our economy is consistent with the Mundell-Tobin effect: increases in inflation are associated with higher nominal interest rates, but lower real interest rates.term structure of interest rates; monetary policy; expected inflation; inflation risk premia; Mundell-Tobin effect

Design of Wireless Sensor Nodes for Structural Health Monitoring applications

Enabling low-cost distributed monitoring, wireless sensor networks represents an interesting solution for the implementation of structural health monitoring systems. This work deals with the design of wireless sensor networks for health monitoring of civil structures, specifically focusing on node design in relation to the requirements of different structural monitoring application classes. Design problems are analysed with specific reference to a large-scale experimental setup (the long-term structural monitoring of the Basilica S. Maria di Collemaggio, L’Aquila, Italy). Main limitations emerged are highlighted, and adopted solution strategies are outlined, both in the case of commercial sensing platform and of full custom solutions

Multi-Sectoral Cascading and Price Dynamics - A Bayesian Econometric Evaluation

Recent evidence by Bils and Klenow (2004) and Klenow and Kryvstov (2003) shows that the average price duration for US CPI-basket goods is in the order of one to two quarters, challenging the monetary business cycle research to try and explain how short price durations can nevertheless generate a large degree of aggregate inflation persistence. We empirically test the relevance of a cascading structure of production as an explanation for short price durations and large aggregate inflation persistence. The final good is produced through a chain of intermediate goods, which undergo several processing stages. At each stage the price is set in nominal terms, and can be adjusted only at random intervals. Though each individual price is adjusted frequently, because the final good price embeds the intermediate price movements, it will turn out to have a large degree of stickiness. We estimate the model using Bayesian techniques to evaluate the relative role of indexation, pricing contracts length, and cascading production structure in the US postwar data. The estimation shows that short pricing contracts within the standard Calvo pricing mechanism are compatible with large inflation persistence, and inflation indexation turns out to play a much less relevant role - in other words, it ends up being a reduced-form model for the cascading production structureInflation Inertia, Monetary Policy, Bayesian Estimation, Multisectoral Cascading

Comparative karyotype studies in species of Miltinea Ravenna, Phycella Lindl. and Rhodophiala C. Presl (Amaryllidaceae) from Chile

La familia Amaryllidaceae se encuentra distribuida en diversas regiones de Chile y Sudamérica. De los 11 géneros reconocidos por Ravenna, al menos tres de ellos presentan un reconocido potencial ornamental: Miltinea Ravenna, endémico de Chile y conformado por la especie Miltinea maulensis (Ravenna) Ravenna, Phycella Lindley, endémico de Chile, conformado por cuatro especies y distribuido desde el valle de Elqui hasta la altura de la región de Arauco y Rhodophiala C. Presl. presente en el sur de Brasil, Uruguay, Bolivia, Argentina y Chile conformado por un número aproximado de 40 especies. Actualmente, la información taxonómica tradicional para diferenciar los géneros presentes en Chile es insuficiente. Es por ello que se utilizó la citotaxonomía como una herramienta y fuente de evidencia taxonómica. El objetivo de esta investigación fue realizar un estudio comparativo de los cariotipos en representantes de tres géneros de Amaryllidaceae que crecen en Chile con el fin de ayudar a clarificar la posición taxonómica de ellos. Las especies analizadas fueron: Miltinea maulensis (Ravenna) Ravenna, Phycella australis Ravenna, Rhodophiala araucana (Phil.) Traub, Rhodophiala montana (Phil.) Traub, y Rhodophiala pratensis (Poepp.) Traub. Los resultados obtenidos indicaron que Miltinea maulensis y Phycella australis presentan características cariológicas muy similares, tanto en el número cromosómico, fórmula cariotípica e índices cromosómicos. Estas características permitirían considerar Miltinea como un sinónimo de Phycella. Por último, las tres especies de Rhodophiala analizadas comparten características citológicas muy similares, como por ejemplo, la presencia de una región NOR en el brazo largo del cromosoma 7, idéntico número cromosómico e índices de asimetría de los cariotipos casi iguales.The family Amaryllidaceae is widely distributed in Chile and South America. Ravenna recognized 11 genera and at least three of them have ornamental value: Miltinea Ravenna, endemic to Chile consists of only one species, Miltinea maulensis (Ravenna) Ravenna; Phycella Lindley, endemic to Chile, consisting of four species, distributed from the Elqui valley in Northern Chile up to the Arauco region in the South, and Rhodophiala C. Presl. distributed in Southern Brazil, Uruguay, Bolivia, Argentina and Chile with about 40 species. Currently, traditional taxonomic information is insufficient to differentiate the genera of Amaryllidaceae in Chile. For this reason cytotaxonomy was used as a source of taxonomic evidence. The objective of this research was a comparative study of the karyotypes of the three Amaryllidaceae genera growing in Chile in order to clarify their taxonomic position. The studied species were: Miltinea maulensis (Ravenna) Ravenna, Phycella australis Ravenna, Rhodophiala araucana (Phil.) Traub, Rhodophiala montana (Phil.) Traub, and Rhodophiala pratensis (Poepp.) Traub. The results indicated that Miltinea maulensis and Phycella australis have very similar karyological characteristics: same chromosome number, chromosome karyotype formula, and indexes. Karyological evidence supports the hypothesis that Miltinea is a synonym of Phycella. Further on, the three species of Rhodophiala show similar cytological features, such as the presence of a NOR region on the long arm of chromosome 7, the same chromosome number, and a nearly equal index of karyotype asymmetry.Fil: Baeza, Carlos.
