The ideas of modern macroeconomics provided the intellectual justification of the economic policies of the last 10 to 15 years. It is these ideas which the financial crisis falsified. The dominant paradigm in macroeconomic theory over the past 30 years has been that of rational agents who form...

The recent financial crisis has shown that liquidity fluctuations in asset markets can have a large impact on the real economy. Many central banks started unconventional monetary policies in 2008, but we still have little understanding of optimal monetary and fiscal policies in such an...

It is shown from empirical data that the Keynesian policy of continual stimulus of the US economy over decades has led to a mountain of debt and a destruction of economic growth. The causal mechanism of how this occurs has been identified. Excessive Keynesian monetary stimulation of aggregate...

Empirical data is presented suggesting that high private and, to a lesser extent, public debt levels place a strong drag upon economic growth. A simple, demand-based, cash flow (DBCF) model of the economy is developed, separating out flows by marginal propensity to spend. This approach is both...

The basic asset pricing equation is adapted to include the effects of unemployment, consumers' expectations, the price level and money supply on money market rates and government bond yields. Expected consumption growth is modelled using European unemployment figures and Eurostat Consumer...

The Quarterly Model of Banco de España (MTBE, Modelo Trimestral del Banco de España), is a large-scale macro-econometric model used for medium term macroeconomic forecasting of the Spanish economy, as well as for performing scenario simulations. The model is specified as a large set of error...

This paper asks whether the post-Keynesian or New Keynesian paradigm provides a more realistic description of the effects of fiscal policy on output and consumption. I establish some macro and microeconomic stylized facts on fiscal multipliers and marginal propensities to consume based on the...

Many researchers have recommended to increase public debt in the aftermath of the financial crisis in order to relax borrowing constraints for private households. This advice is based on the common assumption that borrowing conditions of private agents are exogenous to public policy. We study...
