The welfare cost of random consumption fluctuations is known from De Santis (2007) to be increasing in the level of individual consumption risk in the economy. It is also known from Barillas et al. (2009) to increase if agents in the economy care about robustness to model misspecification. In...

This paper presents a two-sector, two-country model showing that inflation in the housing market, a low personal savings rate, and a construction investment boom can contribute to a large current account deficit. In the model, demand by a group of households in the domestic country is...

Many indicators of business and growth cycles have been constructed by both private and public agencies and are now in use as monitoring devices of economic conditions and for forecasting purposes. As these indicators are largely composite constructs using other economic data, their frequency...

This paper derives and estimates an aggregate Euler consumption equation which allows one to compare the importance of collateral constraints and non-separability of consumption and leisure as alternative sources of excess sensitivity of consumption to current income. Estimation results suggest...

We study the effects of aging population on the sustainability of fiscal policy in overlapping generations models with government debt and a pay-as-you-go pension system. The smaller the population growth rate, the lower the maximum sustainable level of deficits. When the utility function is of...

I explore the dynamics in overlapping generations models with pure exchange and lump-sum taxes, when the second period after tax endowment is negative, and contrast the characteristics of equilibria to those of models with positive after tax endowments. In particular, if the intertemporal...

Cancellation of income and substitution effect implied by King-Plosser-Rebelo (1988) preferences breaks tight coefficient restriction between the slope of the Phillips curve and the elasticity of consumption with respect to real interest rate in a sticky price macro model. This facilitates the...

This paper studies the implications of labour taxation in determining the sensitivity of an economy to macroeconomic shocks. We construct a New Keynesian business cycle model with matching frictions of the labour market, where sluggish employment adjustment implies a key role for labour markets...

This paper focuses on productivity dynamics of a firm-worker match as a potential explanation for the ‘unemployment volatility puzzle’. We let new matches and continuing jobs differ in terms of productivity level and sensitivity to aggregate productivity shocks. As a result, new matches have...

Most of the papers in the sticky-price literature are based on a log-linearization around the zero inflation steady state, a simplifying but counterfactual assumption. This paper shows that when trend inflation is considered, both the long-run and the short-run properties of DGE models based on...
