The effects of inflation on real wage dispersion and welfare are studied in a cash-in-advance economy with a Walrasian goods market but a labor market with search friction. In the labor market, firms post wages and both employed and unemployed workers search among the posted wages. In...

The increase in income per capita is accompanied, in virtually all countries, by two changes in the structure of the economy: an increase in the share of government spending in GDP and an increase in female labor force participation. This paper suggests that these two changes are not just...

This paper employs a new global panel data set on innovation related variables to examine patterns of R&D investment across the development process. We find that R&D effort measured as a share of GDP rises with development at an increasing rate, but that several countries have experienced...

This paper estimates dynamic random effects models for intakes by 100 Kenyan school children (6-9 years) of dietary energy, protein, calcium, iron, zinc, niacin, riboflavin, thiamin, and vitamins A, C, D, and E within a multivariate longitudinal framework. The explanatory variables were...

The increase in income per capita is accompanied, in virtually all countries, by two changes in the structure of the economy: an increase in the share of government spending in GDP and an increase in female labor force participation. This paper suggests that the changes in female labor force...

This paper develops a limiting theory for Wald tests of weak exogeneity in error correction models (ECMs). It is well known that Wald statistics on cointegrated systems may involve nonstandard distribution and nuisance parameters, if $I(1)$ variables are not negligible in the statistics. To...

This paper proposes a new empirical representation of US inflation expectations in a Stace-Space Markov-Switching framework in order to identify the expectations regimes which are associated with short and long term Phillips curves. Results suggest that the dynamics of in‡ation expectation...

Abstract: The paper analyzes cyclical comovements in the Mercosur area differentiating idiosyncratic from common shocks. In the Mercosur (or any region for that matter) shocks can be country-specific, affecting only one country or a specific set of countries (for example, a weather-related...

We introduce continuous-time models that capture the salient features of the short-term interest rate and remain tractable for asset pricing applications. We extend classical specifications within and outside of the affine class to multi-factor settings with latent variables that are readily...

This article studies two extensions of the compound Poisson process with iid Gaussian innovations which are able to characterize important features of high frequency security prices. The first model explicitly accounts for the presence of the bid/ask spread encountered in price-driven markets....
