Numerical simulation of nonoptimal dynamic equilibrium models
In this paper we present a recursive method for the computation of dynamic competitive equilibria in models with heterogeneous agents and market frictions. This method is based on a convergent operator over an expanded set of state variables. The fixed point of this operator defines the set of all Markovian equilibria. We study approximation properties of the operator as well as the convergence of the moments of simulated sample paths. We apply our numerical algorithm to two growth models, an overlapping generations economy with money, and an asset pricing model with financial frictions.

The effects of wealth bubbles on consumption
Changes in wealth, according to our simple calculations, can account for almost all of the observed consumption fluctuations of the past two decades.

\\"Frictions in financial and labor markets\\": a summary of the 35th Annual Economic Policy Conference
This article contains synopses of the papers presented at the 35th Annual Economic Policy Conference of the Federal Reserve Bank of St. Louis held October 21-22, 2010. The conference theme was ?Frictions in Financial and Labor Markets.? Leading participants in this field presented their research and commentary.

Can trade links transmit a European crisis?
A GIIPS crisis wouldn't have too strong an effect on the U.S. economy, but an EU-wide crisis may be a serious concern.

Households during the Great Recession: the financial accelerator in action?
Households are the sector that the financial accelerator appears to have hit hardest, according to the data.

The U.S. financial sector's value added: trends now and then
The U.S. financial growth between 1995 and 2006 certainly translated into record-high shareholder returns. Labor compensation returns were also dramatically high at the onset of the current crisis.

The effects of female labor force participation on obesity
This paper assesses whether a causal relationship exists between recent increases in female labor force participation and the increased prevalence of obesity amongst women. The expansions of the Earned Income Tax Credit (EITC) in the 1980s and 1990s have been established by prior literature as having generated variation in female labor supply, particularly amongst single mothers. Here, we use this plausibly exogenous variation in female labor supply to identify the effect of labor force participation on obesity status. We use data from the National Health Interview Survey (NHIS) and replicate ...

Reconstructing the Great Recession
This article uses dynamic equilibrium input-output models to evaluate the contribution of the construction sector to the Great Recession and the expansion preceeding it. Through production interlinkages and demand complementarities, shifts in housing demand can propagate to other economic sectors and generate a large and sustained aggregate cycle.

A macroeconomic analysis of obesity
This paper tries to understand the underlying causes of the rapid increase in obesity rates over recent decades. In particular, we propose a dynamic general equilibrium model to derive the quantitative implications of a decline in the relative (monetary and time) cost of food prepared away from home on the caloric intake of the average American adult over the last forty years. Two channels that lower this relative cost are considered. First, productivity improvements in the production of food prepared away from home. We and that this channel is qualitatively consistent with expenditure trends ...
