Representative models of the macroeconomy (RMs), such as DSGE models, frequently contain unobserved variables. A finite-order VAR representation in the observed variables may not exist, and therefore the impulse responses of the RMs and SVAR models may differ. We demonstrate this divergence...

The framework used to endogenise technology growth by Acemoglu, Aghion, Bursztyn, and Hemous (2012), hereafter AABH, allows the existence of unstable equilibria and does not provide a rationale for specifying which equilibrium should apply when more than one exists. This paper: (i) suggests a...

The political accord struck by world leaders at the United Nations negotiations in Copenhagen in December 2009 allows participating countries to express their greenhouse gas commitments in a variety of ways. For example, developed countries promised different percent emissions reductions...

Per capita carbon emissions are an important concept in international negotiations of climate policies and also in future projections of aggregate carbon emissions. This paper argues that the convergence studies on per capita carbon emissions in the literature are theoretically biased because...

We explore how and by how much the values of elasticities of substitution affect estimates of the cost of emissions reduction policies in computable general equilibrium (CGE) models. We use G-Cubed, an intertemporal CGE model, to carry out a sensitivity and factor decomposition analysis. Average...

The paper examines climate mitigation strategies to reach net-zero emissions by mid-century, focusing on smoothing macroeconomic costs in the short- to medium-term - the horizon relevant for policymakers. It explores a comprehensive policy package, which complements carbon pricing with an...

Using a unique dataset on daily foreign exchange intervention and a new methodological framework of a latent factor model of central bank intervention, this paper addresses the effects of intervention in an emerging market. Events in financial markets from 2002 to 2010 provide a natural...

We study the response of a three-sector commodity-exporter small open economy to a commodity price boom. When the economy has access to international borrowing and lending, a temporary commodity price boom brings about the standard wealth effect that stimulates demand and has long-run...

This paper explores the domestic and international effects of an increase in observed interest rates (conventional monetary policy) and expected interest rates (forward guidance). We find significant spillovers to a broad range of countries when both are subject to a tightening shock: Output...
