Business cycles in emerging economies: the role of interest rates

by Pablo A. Neumeyer, Fabrizio Perri, O Alvarez, Isabel Correia, Patrick Kehoe, Enrique Mendoza, Juan Pablo Nicolini, Martin Schneider - Journal of Monetary Economics
"... We find that in a sample of emerging economies business cycles are more volatile than in developed ones, real interest rates are countercyclical and lead the cycle, consumption is more volatile than output and net exports are strongly countercyclical. We present a model of a small open economy, wher ..."

Grounding language in action

by Arthur M. Glenberg, Michael P. Kaschak - Psychonomic Bulletin & Review , 2002
"... We report a new phenomenon associated with language comprehension: the action–sentence compatibility effect (ACE). Participants judged whether sentences were sensible by making a response that required moving toward or away from their bodies. When a sentence implied action in one direction (e.g., “C ..."

, and sentences describing the transfer of abstract entities, such as “Liz told you the story. ” These data are inconsistent with theories of language comprehension in which meaning is represented as a set of relations among nodes. Instead, the data support an embodied theory of meaning that relates the meaning

Benchmarking cloud serving systems with ycsb

by Brian F. Cooper, Adam Silberstein, Erwin Tam, Raghu Ramakrishnan, Russell Sears - SoCC
"... While the use of MapReduce systems (such as Hadoop) for large scale data analysis has been widely recognized and studied, we have recently seen an explosion in the number of systems developed for cloud data serving. These newer systems address “cloud OLTP ” applications, though they typically do not ..."

not support ACID transactions. Examples of systems proposed for cloud serving use include BigTable, PNUTS, Cassandra, HBase, Azure, CouchDB, SimpleDB, Voldemort, and many others. Further, they are being applied to a diverse range of applications that differ considerably from traditional (e.g., TPC-C like

Openness and Inflation: Theory and Evidence

by David Romer - Quarterly Journal of Economics , 1993
"... Because unanticipated monetary expansion leads to real exchange rate depreciation, and because the harms of real depreciation are greater in more open economies, the benefits of unanticipated expansion are decreasing in the degree of openness. Models in which the absence of precommitment in monetary ..."

in monetary policy leads to excessive inflation therefore predict lower average inflation in more open economies. This paper tests this prediction using cross-country data. The data show a strong and robust negative link between openness and inflation. I.

Geometric diffusions as a tool for harmonic analysis and structure definition of data: Diffusion maps

The Variety and Quality of a Nation’s Exports

by Hummels, Peter J. Klenow - American Economic Review , 2005
"... Large economies export more in absolute terms than do small economies. We use data on shipments by 126 exporting countries to 59 importing countries in 5,000 product categories to answer the question: How? Do big economies export larger quantities of each good (the intensive margin), a wider set of ..."

Semantic Wikipedia

by Max Völkel, Markus Krötzsch, Denny Vrandecic, Heiko Haller, Rudi Studer , 2006
"... Wikipedia is the world’s largest collaboratively edited source of encyclopaedic knowledge. But its contents are barely machineinterpretable. Structural knowledge, e. g. about how concepts are interrelated, can neither be formally stated nor automatically processed. Also the wealth of numerical data ..."

Default risk and income fluctuations in emerging economies’. Working Paper

by Cristina Arellano - American Economic Review , 2005

, with the economies of China and India expanding with double digit growth rates, Asia can become a much larger source of ABCs, depending on the energy path taken to sustain this growth rate. In fact new estimates indicate that BC emissions for China in 2006 have doubled since 2000, whereas SO2 emissions have grown
