We analyse the M-theoretic generalisation of the tangent space structure group after reduction of the D = 11 supergravity theory to two space-time dimensions in the context of hidden Kac–Moody symmetries. The action of the resulting infinitedimensional ‘R symmetry’ group K(E9) on certain unfaithful, finite-dimensional spinor representations inherited from K(E10) is studied. We explain in detail...

Search is embeded in an overlapping-generations model. Young people participate a centralized market and a decentralized market sequentially and olds only participates the centralized market. The demographic feature allows analytical tractability. In a series examples, positve inflation rates are Pareto optimal. JEL classification: E31

Differential tax analysis is used to show how the socially optimal fiscal-tax to liquidity-tax ratio changes with the relative size of the tax-evading hidden economy. The smaller the relative size of the hidden economy, the larger the optimal fiscal-tax to liquidity-tax ratio. The empirical cross-section and panel evidence supports this theoretical result.

This paper estimates a structural VAR model of U.S. consumer and world commodity prices. An equiproportional long-run response of nominal price levels to amonetary shock yields identifying restrictions. Exogenous innovations tomonetary policy account for a sizable share of the co-movement of these series, including during episodes more commonly attributed to “supply shocks.” JEL Categories: C32...

This paper presents out-of-sample inflation forecasting results based on relative price variability and skewness. It is demonstrated that forecasts on long horizons of 1.5-2 years are significantly improved if the forecast equation is augmented with skewness. JEL: E17, E31, C43

Boschen and Weise (Journal of Money, Credit and Banking, 2003) model the probability of a large upturn in in‡ation. We extend their work to show that openness to trade exerts a negative e¤ect on the probability of such an event. Keywords: In‡ation starts, trade openness. JEL classi…cation: E31, F41.

Growing environmental concerns over global warming and depleting fossil fuel reserves are compelling researchers to investigate green fuels such as alcoholic that not only show the concrete decrement in emissions but also enhance engine performance. The current study emphasizes influence of different blends gasoline on performance for an speed ranging from 1200 4400 rpm. obtained results demons...

Page e10 Obesity is a chronic multifactorial desease whose increasing prevalence is associated with several comorbidities. Diabetes, cardiovascular diseases, musculoskeletal diseases, mental health problems and even certain cancers are more common among obese patients. According to World Health Organization (WHO), obesity is one of the ten responsible for more than a third of deaths, being the ...

In this paper we develop the first search-theoretic monetary model of a two-country global economy. We show the connection between deep monetary frictions (i.e. search and matching frictions), capital holdup externalities, and the realization of an endogenous departure from the “excess smoothness” problem in the real exchange rate found in standard models. Using this alternative monetary model,...
