The recent literature on endogenous economic growth allows for effects of fiscal policy on long-term growth. If the social rate of return on investment exceeds the private return, then tax policies that encourage investment can raise the growth rate and levels of utility. An excess of the social...

The empirical evidence reveals conditional convergence in the sense that economies grow faster per capita if they start further below their steady-state positions. For a homogeneous group of economies - like the U.S. states, regions of western European countries, and the GECD countries - the...

This paper explores the five simplest models of endogenous growth. We start with the AK model (Rebelo (1990)) and argue that all endogenous growth models can be viewed as variations or microfoundations of it. We then examine the Barro (1990) model of government spending and growth. Next we look...

In this paper we study the effects of policies of financial repression on long term growth and try to explain why optimizing governments might want to repress the financial sector. We also explain why inflation may be negatively related to growth, even though it does not affect growth directly....

This is a survey of the literature on Economic Growth. In the introduction we analyze the main differences between exogenous and endogenous growth models using fixed savings rate analysis. We argue that in order to have endogenous growth there must be constant returns to the factors that can be...

We construct a model that combines elements of endogenous growth with the convergence implications of the neoclassical growth model. In the long run, the world growth rate is driven by discoveries in the technologically leading economies. Followers converge toward the leaders because copying is...

A key economic issue is whether poor countries or regions tend to grow faster than rich ones: are there automatic forces that lead to convergence over time in levels of per capita income and product? After considering predictions of closed- and open-economy neoclassical growth theories, we...

Concerns about the quality of China's official GDP statistics have been a perennial question in understanding its economic dynamics. We use data on satellite-recorded nighttime lights as an independent benchmark for comparing various published indicators of the state of the Chinese economy....

The dismal growth performance of Africa is the worst economic tragedy of the XXth century. We document the evolution of per capita GDP for the continent as a whole and for subset of countries south of the Sahara desert. We document the worsening of various income inequality indexes and we...

Some natural resources -- oil and minerals in particular -- exert a negative and nonlinear impact on growth via their deleterious impact on institutional quality. We show this result to be very robust. The Nigerian experience provides telling confirmation of this aspect of natural resources....
