We develop a tractable dynamic model of productivity growth and technology spillovers that is consistent with the emergence of real world empirical productivity distributions. Firms can improve productivity by engaging in in-house R\&D, or alternatively, by trying to imitate other firms'...

I use U.S. manufacturing industry data to estimate a system of three equations implied by a model of R&D-induced growth in steady state. These three equations relate R&D intensity to patenting, patenting to technological progress, and technological progress to economic growth. In each case, I...

We model distribution, the delivery of goods to customers, as an activity governed by its own technology and undertaken by firms subsequently to production operations. We then use the model to investigate how distribution shapes innovation-driven economic growth. We contrast two canonical...

We present a discrete-time version of an otherwise standard Schumpeterian growth model. Discrete time exhibits two important differences from continuous time. First, the probability of successful innovation cannot be homogeneous of degree one in inputs. A natural R&D analogue to constant returns...

Schumpeterian growth theory has operationalized Schumpeter’s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process that could not be properly addressed by alternative theories. In this survey, we focus on...

This paper focuses on the growth and convergence of Central, Eastern and South-Eastern European EU countries (CESEE). We argue that the factors behind the pre-crisis growth model of the region - skilled yet affordable labour force, foreign direct investment, imports of productivity-enhancing...

We show a causal impact of immigration on innovation and dynamism in US counties. To identify the causal impact of immigration, we use 130 years of detailed data on migrations from foreign countries to US counties to isolate quasi-random variation in the ancestry composition of US counties that...

New Örms are often based on ideas that the founders developed while working for incumbent Örms. We study the macroeconomic e§ects of spino§s through a growth model of product variety expansion, driven by Örm entry, and product innovation. Spino§s stem from conáicts of interest between...

We construct a competitive model of innovation and growth under constant returns to scale. Previous models of growth under constant returns cannot model technological innovation. Current models of endogenous innovation rely on the interplay between increasing returns and monopolistic markets. In...

In this chapter we argue that the endogenous growth model with quality-improving innovations provides a framework for analyzing the determinants of long-run growth and convergence that is versatile, simple and empirically useful. Versatile, as the same framework can be used to analyze how growth...
