A well known result is that the Gaussian log-likelihood can be expressed as the sum over different frequency components. This implies that the likelihood ratio statistic has a similar linear decomposition. We exploit these observations to devise diagnostic methods that are useful for...

The size and sign of the government spending multiplier crucially depends on how the spending is financed and how consumers respond to implied future tax increases. I investigate this issue in an estimated New Keynesian DSGE model with distortionary labor and capital taxes and, importantly, with...

This paper focuses on an econometric investigation of the macroeconomic and political factors that contributed to Greece’s excessive debt accumulation and its failure to adequately address its fiscal imbalances, from the restoration of democracy in 1974 till the crisis of 2009. The econometric...

This paper presents a political economy model of inflation as a result of social conflict. Agents are heterogeneous in terms of income. Agents’ income levels determine their ability to hedge against the effects of inflation. The interaction of heterogeneous cash holdings and preferences over...

A reduction in income tax rates generates substantial dynamic responses within the framework of the standard neoclassical growth model. The short-run revenue loss after an income tax cut is partly - or, depending on parameter values, even completely - offset by growth in the long-run, due to the...

The latest economic growth figures confirm that the UK economy is slowly recovering from the deep recession of 2008/09. But according to researchers at the Centre for Economic Performance (CEP), the recovery will probably continue to be slow, and there is still no sign of a significant reversal...

Labor market institutions, via their effect on the wage structure, affect the investment decisions of firms in labor markets with frictions. This observation helps explain rising wage inequality in the US, but a relatively stable wage structure in Europe in the 1980s. These different trends are...

This paper investigates the relationship between infation uncertainty and investment using a panel of loan-level data from small businesses. Micro-level data makes it possible to study phenomena that are obscured in country or industry aggregates. The data show that periods of increased...

Whether or not the marginal product of capital (MPK) differs across countries is a question that keeps coming up in discussions of comparative economic development and patterns of capital flows. We use easily accessible macroeconomic data to shed light on this issue, and find that MPKs are...
