We disentangle the contribution of unobserved heterogeneity in idiosyncratic demand and productivity to firm growth. We use a model of monopolistic competition with Cobb-Douglas production and a dataset of Italian manufacturing firms containing unique information on firm-level prices to reach...

Two otherwise identical firms that enter the same market in different months, one in January and one in December, will report dramatically different annual sales for the first calendar year of operations. This partial year effect in annual data leads to downward biased observations of the level...

This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...

We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behaviour of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological...

This paper considers the sources of long-term economic growth for Turkey over the period 1880-2005. The period in question covers the decline and eventual dissolution of the former Ottoman Empire and the emergence of the new Turkish Republic in 1923. Hence, the paper provides a unique look at...

This paper shows that fiscal policy, when used for stabilization purposes, can have a positive effect on the economy's growth, on human capital accumulation, and on welfare, along the transition path. We introduce symmetric productivity shocks into a model in which productivity is augmented...

We construct and numerically solve a dynamic Heckscher-Ohlin model in which the initial distribution of production factors in the world makes worldwide factor price equalization impossible, and leads countries to group in two diversification cones. We study the dynamics of income per capita and...

An unstable macroeconomic environment is often regarded as detrimental to economic growth. Among the sources contributing to such instability, the literature has assigned most of the blame to political issues. This paper empirically tests for a causal and negative long-term relationship between...

This paper develops empirical growth models suitable for dual economies, and studies the relationship between structural change and economic growth. Structural change matters because, if the marginal product of labour varies across sectors, changes in the structure of employment can raise...
