This paper proposes a new methodology for generating sovereign credit ratings. These are determined by mapping the probability that the debt-GDP ratio might exceed a maximum debt limit at some point in the future into a credit rating. The debt limit can be either ad hoc or based on the financial...

We argue that the conventional approach to assessing the fiscal stance based on econometric tests of the government present value budget constraint (PVBC) is of limited practical use. We propose an alternative measure that focuses on short-run fluctuations in the fiscal stance, namely, a...

In this paper we propose a new way to formulate optimal policy based on a quadratic intertemporal welfare function where the dynamic constraint is based on a VAR model of the economy which we call the PVAR method. We argue that the VAR under control should not be derived simply by replacing the...

We propose a model-based measure of sovereign credit ratings derived solely from the fiscal position of a country: a forecast of its future debt liabilities, and its potential to use tax policy to repay these. We use this measure to calculate credit ratings for fourteen European countries over...

This paper argues that the crisis was an outcome of EMU: setting a common monetary policy for countries with different initial inflation rates. The crisis countries were those with high inflation rates which then had negative real interest rates and consequently over-borrowed. Current policy...

The immediate background to this paper is the downgrade of the U.K.'s credit rating in February 2013, the market's view that this should have occurred earlier and the emphasis in fiscal policy on reducing debt rather than recovery from recession. We propose a measure of the U.K. sovereign credit...

A methodology for generating sovereign credit ratings based on macroeconomic theory is proposed. This is applied to quarterly U.S. data from 1970 to 2011. Over this period the official credit rating of U.S. Treasury securities has been of the highest quality. In contrast, the model-based measure...
