What is the output gap? There are many definitions in the economics literature, all of which have a long history. I discuss three alternatives: the deviation of output from its long-run stochastic trend (i.e., the "Beveridge-Nelson cycle"); the deviation of output from the level consistent with...

The expansion in the supply of energy services over the last couple of centuries has reduced the apparent importance of energy in economic growth despite energy being an essential production input. We demonstrate this by developing a simple extension of the Solow growth model, which we use to...

Against the backdrop of Baumol’s model of ‘unbalanced growth’, a recent strand of literature has presented models that manage to reconcile structural change with Kaldor’s ‘stylized fact’ of the relative constancy of per-capita GDP growth. Another strand of literature goes beyond...

Literature notes many factors as affecting capital flows, but the effects of these flows over the recipient economies and the overall effect over growth are highly debatable. This study claims that although capital flows may be required for the increase in output, other forces are causing this...

In this paper, we test whether the growth experience of a sample of OECD countries over the past three decades is more consistent with the human-capital augmented Solow model of exogenous growth, or with an endogenous growth model à la Uzawa-Lucas with constant returns to scale to broad (human...

This paper notes that the Mankiw, Romer, and Weil formulation of the augmented Solow growth model has implications not only for the steady-state growth rates but also for how these growth rates would change if there are changes in fundamentals. The analysis supports several of Mankiw, Romer, and...

This paper describes the correlations between inequality and the growth rates in cross-country data. Using non-parametric methods, we show that the growth rate is an inverted U-shaped function of net changes in inequality: Changes in inequality (in any direction) are associated with reduced...
