Should one think of zero nominal interest rates as an undesirable liquidity trap or as the desirable Friedman rule? I use three different frameworks to discuss this issue. First, I restate Cole and Kocherlakota's (1998) analysis of Friedman's rule: short run increases in the money stock -...

This paper investigates in a consistent semi-structural empirical framework three current issues of monetary policy in the euro area. First, regarding policy transmission we offer a three-stage procedure to combine the efficient estimation of economic structure prior to EMU with current ECB...

This paper examines the impact of macroeconomic policy shocks in a Real- Business-Cycle Model with money. In addition to technology shocks, I include government consumption, government investment, tax rate and monetary policy as sources of random disturbances. Money is introduced in a...

This paper attempts to provide an empirical determination of the Philippine central bank's (BSP) recent monetary policy stance, before and after its adoption of the inflation targeting framework, as revealed by its interest rate setting behavior. Employing Clarida, Gali, and Gertler's (1998,...

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...

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 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...

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....

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...
