New developments in inflationary models
We study models of inflation where the inflaton corresponds to a flat direction in field space and its mass term is generated by gravity mediated soft supersymmetry breaking at high scale. Assuming the inflaton to have non negligible couplings to other fields, its mass runs with scale and can reach the small value required by slow roll inflation at a lower scale, even if its initial value is to...
متن کاملMarket Power in Macroeconomic Models: New Developments
– Earlier work on the market-power foundations of macroeconomics (see Silvestre, Journal of Economic Literature, 1993) adopted static or temporary equilibrium models. This paper surveys the more recent litterature, which is explicitly dynamic (models of overlapping generations, equilibrium fluctuations or neoclassical growth). The issues discussed include: (a) unemployment at low wages; (b) red...
متن کاملSome New Developments in Small Area Estimation
Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...
متن کامل1 New Developments in Latent Class Choice Models
Discrete choice models have proven to be good methods for predicting market shares for new products based on consumers' expressed preferences between choice alternatives. However, the standard aggregate model fails to take into account the fact that preferences (utilities) differ from one respondent to another (or at least from one segment to another). This failure often yields poor share predi...
متن کاملNew Developments in Non-hermitian Random Matrix Models
Random matrix models provide an interesting framework for modeling a number of physical phenomena, with applications ranging from atomic physics to quantum gravity 1, . In recent years, non-hermitian random matrix models have become increasingly important in a number of quantum problems 3, . A variety of methods have been devised to calculate with random matrix models. Most prominent perhaps ar...
