Closed string tachyon condensation in spacetime generates potentials on the worldsheet that model two-dimensional inflationary cosmology. These models illustrate and elucidate a variety of aspects of inflation, in particular the generation of quantum fluctuations and their back-reaction on geometry. We exhibit a class of Liouville gravity models coupled to matter that can exhibit, for example: ...

Inflation targeting has become the predominant monetary approach across the globe. In this paper, we examine the inflation targeting experience in developing countries. We estimate the effects of inflation targeting on macroeconomic performance in these economies. The approach is based on the methodology applied by Pétursson (2005) which uses panel data to assess the effects of inflation target...

The EU acceding countries are supposed to adopt the Euro as soon as economic convergence is achieved. This paper offers a methodology to quantify the economic consequences of an acceding country’s EMU entrance. A small macroeconomic two-country model is specified and combined with two different monetary policy regimes: (i) national monetary policy, (ii) monetary union. The performance of the tw...

This study is about the earnings-replacement rate of the old-age benefit for the average worker in manufacturing who had average earnings throughout his career. It updates previously published data for earlier years and compares the replacement rate of the combined social security and private pension benefits for selected countries, in an attempt to show what a more complete benefit package mig...

In the wake of steep fall in national savings due to economic shocks, among them COVID-19 pandemic macroeconomic consequences, this study examines what extent inflation explains variation saving behavior developing countries. Most past empirical studies investigated role on only advanced nations. The current will investigate effect culture Kenya. To determine how saving, use s ordinary least sq...

Currently a new version of the distance education platform WeLearn [3] to be combined with an agent system ([1], also developed locally) for providing advanced services [2] is under development. In a previous stage of the project software was created to automatically derive keywords from documents, either from the different versions of metadata already contained (various Microsoft file formats,...

As our ability to store information increases, the mechanisms we employ to access that information become ever more important. In this paper, we present Archosum, a prototype of an organizational system that attempts to encapsulate the benefits of both hierarchical and keyword systems. By introducing abstract entities, Archosum provides a simple interface with which users can build and maintain...

Advanced knowledge-based hazard algorithms would require better knowledge of ttering characteristics of hydrometeors such as , hailstones, and snowflakes. Especially, characteristics becomes important for utilize phase-array dual-polarization radar Traditionally, theoretical approaches [1]...

Describing the nature of the trade-off between inflation and output or unemployment has long been difficult and controversial. The Friedman-Phelps hypothesis, that there is no long-run Phillips curve trade-off between inflation and unemployment, has clearly won over most macro-. economists, but the debate has continued over what, if any, trade-off remains. The subtle notion that an uncertain sh...

Despite the fact that, banks can withstand the effects of inflation in the short run, since banking system mostly operates with reference to interest rate and maturity of financial instruments with less concern about the purchasing power of money. However, the banking system cannot absorb the shocks in the long run. The objective of this paper is to conceptually expose the effect of inflation o...
