The correlation between persistent changes in the markup in one sector of an economy and the inflation rate is quantified in a 2-sector dynamic general equilibrium model. How this relationship is affected by monetary policy is also studied. We find that the correlation is in general positive under an exogenous money growth rule as well as under an inflation targeting rule. That is, a decrease o...

This paper formulates a stylized New Keynesian model in which each individual firm can select the frequency of its price adjustments, and we demonstrate that the endogeneity of the contract structure has a dramatic impact on the magnitude of the aggregate effects of steady-state inflation. We start by analyzing the exact nonlinear properties of a benchmark economy with exogenous contract durati...

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 policy leads to excessive inflation therefore predict lower average inflation in more open econo...

in macroeconomic studies, social welfare is assumed as a function of inflation and unemployment. although the social welfare function which is dependent to unemployment and inflation variables has been used widely in macroeconomic theories, but this relation needs to be tested through empirical observations. this paper, using variables such as to economics of happiness area and subjective wellb...

This study investigates the relationship between globalization and income inequality by developing a new globalization index based on economic growth. In addition two other indices of globalization, non-parametric Kearney and parametric principal component analysis are used as benchmarks to compare the results. The proposed new index is decomposed into four sub components. The index is also est...

We point out that, if quantum field renormalization is taken into account and the counterterms are evaluated at the Hubble-radius crossing time or few e-foldings after it, the predictions of slow-roll inflation for both the scalar and the tensorial power spectrum change significantly. This leads to a change in the consistency condition that relates the tensor-to-scalar amplitude ratio with spec...

Spacetime singularities have been discovered which are physically much weaker than those predicted by the classical singularity theorems. Geodesics evolve through them and they only display infinities in the derivatives of their curvature invariants. So far, these singularities have appeared to require rather exotic and unphysical matter for their occurrence. Here we show that a large class of ...

The essential reason that a 100-percent-reserve gold standard should be the ultimate goal of monetary reform is that it would secure the economic system against the evils both of inflation and of deflation–depression. In addition, it would be consistent with the fundamental moral–political principle of the absence of the initiation of physical force and thus the positive presence of individual ...

We perform a numerical investigation of the fields evolution in the supersymmetric inflationary model based on radiative corrections. Supergravity corrections are also included. We find that, out of all the examined initial data, only about 10% give an adequate amount of inflation and can be considered as ”natural”. Moreover, these successful initial conditions appear scattered and more or less...
