This paper explores zero lower bound (ZLB) economics. The ZLB is widely invoked to explain stagnation and it fits with the long tradition that argues Keynesian economics is a special case based on nominal rigidities. The ZLB represents the newest rigidity. Contrary to ZLB economics, not only...

Over the last decade a new consensus model has emerged in monetary macroeconomics, labelled New Keynesian macroeconomics (Clarida et al., 1999). It consists of three simple building blocs: a forward-looking IS-equation that is derived from the optimization problem of a representative household,...

While the IS/LM-AS/AD model is still the central tool of macroeconomic teaching it has been criticised by several economists. The model is unable to deal with a monetary policy that uses the interest rate as its operating target ( Romer [2000]). Walsh [2002] has criticised that it is not suited...

We study monetary policy under climate change in order to answer the question of whether monetary policy should take into account the expected impacts of climate change. The setup is a new Keynesian dynamic stochastic general equilibrium model of a closed economy in which a climate module that...

This paper provides a critique of zero lower bound (ZLB) economics which has become the new orthodoxy for explaining stagnation. ZLB economics is an extension of pre-Keynesian economics which attributes macroeconomic dysfunction to rigidities and market imperfections. The ZLB is the latest...

100 years after Böhm-Bawerks death and nearly 70 years after Keynes has died there is still fundamental controversy about the factors which determine the interest rate in the long run. While Economists in the Austrian tradition see it as solely driven by real phenomena, Keynesian authors mainly...

A system of thought allowed for the free market price of land to cyclically go down to zero. This is the economics of Moses. The economics of Jesus is a restatement of the economics of Moses. The first was applied during Biblical times and the latter, united with Aristotle’s thought and...

We analyze a recent paper that claims that dollarizing an economy in the presence of a “dollar shortage” will provoke an immediate sharp reduction in real output and welfare. We find many problems with the model that supports this conclusion: confusion about the nature of a dollar shortage...

We assess the role of external debt in shaping the dynamics of domestic credit cycles. Using quarterly data for 40 countries between 1980 and 2015, we examine four dimensions of external debt composition: instrument, sector, currency and maturity. We show that the first two dimensions provide...

We investigate the impact of climate change on the macroeconomic performance of a small open economy. The setup is a new Keynesian dynamic stochastic general equilibrium model of a small open economy without monetary policy independence in which a climate module that interacts with the economy...
