This paper discusses the place of oligopoly in international trade theory, and argues that it is unsatisfactory to ignore firms altogether, as in perfectly competitive models, or to view large firms as more productive clones of small ones, as in monopolistically competitive models.  Doing...

We investigate the properties of the composite likelihood (CL) method for (T x NT) GARCH panels.  The defining feature of a GARCH panel with time series length T is that, while nuisance parameters are allowed to vary across NT series, other parameters of interest are assumed to be common.  CL...

Microfounded macromodels (SDGE models) represent the dominant approach in academic macroeconomics, and their influence now extends to the forecasting models of central banks.  These models appear to adopt a clear methodological approach, which promotes internal consistency above external...

A new test for non-linearity in the conditional mean is proposed using functions of the principal components of regressors.  The test extends the non-linearity tests based on Kolmogorov-Gavor polynomials (Thursby and Schmidt, 1977, Tsay, 1986, and Terasvirta, Lin and Granger, 1993), but...

For some observers, the dramatic growth of the services sector in India reflects rapid strides made by educated professionals.  Some others see it as the expansion of an employer of last resort.  Given this heterogeneity, the object of the paper is to analyze the nature of employment being...

This paper presents new models for aggregate UK data on mortgage possessions (foreclosures) and mortgage arrears (payment delinquencies).  The innovations include the treatment of difficuly to observe variations in loan quality and shifts in forbearance policy by lenders, by common latent...

We model the interplay between a government's performance, its expected lifetime, and the confidence it enjoys. Here, "confidence" can be broadly interpreted as the government's popularity, the size of its parliamentary majority, its reserve of talent, or other factors. Confidence evolves in...

The idea of the 'L-shaped aggregate supply curve', supposedly a feature of primitive macroeconomic models, is in fact a reasonable reconstruction of a well developed way of thinking that specifically denied a relation between wage change and aggregate employment.  Neither that approach nor the...

An individual's learning rule is completely uncoupled if it does not depend on the actions or payoffs of anyone else.  We propose a variant of log linear learning that is completely uncoupled and that selects an efficient pure Nash equilibrium in all generic n-person games that possess at least...

This paper explores the role of culture in determining divorce decisions by examining differences in divorce rates by country of origin of immigrants in the United States.  Because immigrants who arrived in the US at a young age are all exposed to a common set of American laws and institutions,...
