In 2011, the publicly held debt-to-GDP ratio in the United States reached 68% and is expected to continue rising. Many proposals to curb the government de…cit and the resulting debt are being discussed. In this paper, we use the standard neoclassical growth model to examine the future path of output, budget de…cits, and debt in the U.S. economy under di¤erent tax policies. While this framework ...

Objective Fungi produce many different carotenoids and some are attractive in medical and industrial sources. In this work the ability of Mucor hiemalis (PTCC 5292) to produce carotenoids in media with different nitrogenous and carbon sources and incubation with white, yellow, blue and red lights (15W, 220V, E27) against dark-grown were studied. Materials and Method The microorganism cultiva...

This paper focuses on developing models to study influential factors on the inflation rate for a panel of available countries in the World Bank data base during 2008-2012‎. ‎For this purpose‎, Random effect log-linear and Ordinal logistic models are used for the analysis of continuous and categorical inflation rate variables‎. ‎As the original inflation rate response to variables shows an appar...

Three experiments examined the e€ect of costs associated with investments on the judgments of the causal e€ectiveness of those investments, and on the type of information utilised when making those judgements. Using operant conditioning technology, in an experimental analogue of making economic investments, it was found that greater costs associated with an investment reduced the judgement abou...

When a boom ends, the downturn is generally sharp and short. When growth resumes, the boom is more gradual. Our explanation rests on learning about productivity. When agents believe productivity is high, they work, invest, and produce more. More production generates higher precision information. When the boom ends, precise estimates of the slowdown prompt decisive reactions: Investment and labo...

In many countries, wage changes tend to be clustered in the beginning of the year, with wages being set for xed durations of typically one year. This has been, in particular, documented in recent years for European countries using microeconomic data. Motivated by this evidence we build a model of uneven wage staggering, embedded in a standard DSGE model of the euro area, and investigate the mon...

Background—Progenitor CD34 cells are capable of differentiating into endothelial cells and play a role in neoangiogenesis. Circulating CD34 cells and endothelial progenitor cells are increased in acute coronary syndrome (ACS) patients possibly because of peripheral mobilization. We tested the hypothesis that circulating apoptotic progenitors are detectable in healthy subjects and altered in ACS...
