Leith and Wren-Lewis (2007) have shown that government debt is returned to its pre-shock level in a New Keynesian model under optimal discretionary policy. This has two important implications for monetary and fiscal policy. First, in a high-debt economy, it may be optimal for discretionary...

This paper studies the implications of adaptive learning in the modelling of international linkages in a two-region MSG-Cubed (MSG3) model built on micro-founded behaviours of firms and households. The nature of the transmission process under rational expectations versus the adaptive learning...

This paper investigates welfare gains and channels of risk sharing among 14 Middle Eastern and North African (MENA) countries, including the oil-rich Gulf region and the resource scarce economies such as Egypt, Morocco and Tunisia. The results show that, for the 1992-2009 period, the overall...

The early 21st century saw Australia experience its largest and longest terms of trade boom. This paper places this recent boom in a long-run historical context by comparing the current episode with earlier cycles. While similarities exist across most episodes, current macroeconomic policy...

This paper proposes a simple framework that generalizes the timing structure of macroeconomic (as well as other) games. Building on alternative move games and models of "rational inattention" the players' actions may be rigid, ie optimally chosen to be infrequent. This rigidity makes the game...

Opponents of inflation targeting have argued that a commitment to a numerical inflation target reduces policy's stabilization flexibility - increasing output volatility under supply shocks. Using a novel game theoretic approach our paper demonstrates that this claim may fail to account for the...

The importance of the time-consistency poblem depends critically on the model one is working with and its parameterizations. This paper attempts to quantify the magnitude of stabilization bias for a small open economy using an empirically estimated micro-founded dynamic stochastic general...

Monetary and fiscal policies interact in many ways. Recently, the stance of fiscal policy in a number of countries (including the EU and the US) has raised concerns about risks for the outcomes of monetary policy. Our paper first shows that these concerns are justified since - under an ambitious...
