Accumulating microeconomic evidence points both to firm level adjustment lumpiness and to the significant influence of idiosyncratic disturbances. Do these matter for aggregate fluctuations, or do their effects largely vanish upon aggregation? This paper explores the implications of local...

This paper extends the standard Real Business Cycle model to incorporate sectoral shifts in unemployment. Using relative sectoral technology and sectoral tastes shocks, combined with labor adjustment costs across sectors, we assess the possibility of generating persistent aggregate unemployment....

In this paper, we provide a dynamic general equilibrium framework with an explicit investment-financing constraint. The constraint is intended as a reduced form to capture the balance sheet effects that have been widely regarded as an important determinant of financial crises. We derive a link...

Stackelberg differential games are useful settings in which optimal government policies can be studied. This paper argues that the analysis of these games involves a key technical issue. In particular, we question the necessity for optimality of one boundary condition invoked in existing...

This paper studies consumption dynamics and welfare losses under information processing constraints (it is also called 'rational inattention' (RI) in Sims (2003)) in the permanent income hypothesis (PIH) model. It is shown that incorporating RI into the otherwise standard PIH model can...

We consider linear dynamic models with rational expectations in case of incomplete and asymmetric information as well as agents heterogeneity. This problem requires solving infinite dimensional matrix equations. We propose asymptotic expansion method to reduce this problem to the finite...

In the Universe of Development Economics, Social Development is represented by Endogenous Circle linking Domestic Technology with Domestic Human Potential (Technical Infrastructure) & Economic Development is represented by Exogenous Circle linking Domestic Investment with Domestic Saving...

The cyclical behavior of hours worked, wages, and consumption does not conform with the prediction of the representative agent with standard preferences. The residual in the intra-temporal first-order condition for commodity consumption and leisure is often viewed as a failure of labor-market...

This paper suggests that skill accumulation through past work experience, or ``learning-by-doing'' (LBD), can provide an important propagation mechanism in a dynamic stochastic general equilibrium model, as the current labor supply affects future productivity. Our econometric analysis uses a...

The “neoclassical synthesis” sticky price model exhibits strange behavior when augmented with markets for durable goods with flexible prices. While in the data the output of durable goods responds strongly and positively to a loosening of monetary policy, in dynamic general equilibrium...
