Losing a parent is a trauma that has consequences for human capital formation. Does it matter at what age this trauma occurs? Using longitudinal data from the Kagera region in Tanzania that span thirteen years from 1991-2004, we find considerable impact heterogeneity across age at bereavement,...

This paper estimates the aggregate productivity effects of Marshallian externalities generated by foreign direct investments (FDI) in the US. In contrast to earlier work, this paper puts special emphasis on controlling for Marshallian externalities and other intra- and inter-regional spillovers...

How inflation and unemployment are related in both the short run and long run is perhaps the key question in macroeconomics. This paper tests various price equations using quarterly U.S. data from 1952 to the present. Issues treated are the following. 1) Estimating price and wage equations in...

This paper argues that there is a nonzero inflation-unemployment tradeoff in the long-run due to frictional growth, a phenomenon that encapsulates the interplay of nominal staggering and money growth. The existence of a downward-sloping long-run Phillips curve suggests the development of a...

We assess the empirical relevance for inflation dynamics of accounting for the presence of search frictions in the labor market. The New Keynesian Phillips curve explains inflation dynamics as being mainly driven by current and expected future marginal costs. Recent empirical research has...

In this paper we introduce and test the hypothesis that the relation between inflation and unemployment has been in many countries subject to a significant change in the early 1990's after the disinflation period. That period began between 1975 and 1980 after the first (or the second) oil price...

This paper re-examines the validity of the Phillips-Curve framework using US data. We make three main innovations. First, we introduce into the well-known Calvo price staggering framework, a regime-dependent price-changing signal. This means that a state-dependent linearization is no longer...

The canonical new Keynesian Phillips Curve has become a standard component of models designed for monetary policy analysis. However, in the basic new Keynesian model, there is no unemployment, all variation in labor input occurs along the intensive hours margin, and the driving variable for...
