We combine growth theory with US Census data on individual schooling and wages to estimate the aggregate return to human capital and human capital externalities in cities. Our estimates imply that a one-year increase in average schooling in cities increases their aggregate labor productivity by...

The systems of innovation (SI) approach has been established and extended during the last two decades. Although elementary goals and progress have been reached through seminal contributions by Freeman (1987), Lundvall (1992) or Nelson (1993), in designing a generic approach, displaying the...

This article analyzes empirically the main existing theories on income and population city growth: increasing returns to scale, locational fundamentals and random growth. To do this we implement a threshold nonlinearity test that extends standard linear growth regression models to a dataset on...

This paper explores the local stability properties of the steady state in the twosector neoclassical growth model with sector specific externalities. We show analytically that capital adjustment costs of any size preclude local indeterminacy nearby the steady state for every empirically...

This paper examines the relationship between inequality and growth in the neo-Kaleckian and Cambridge growth models. The paper explores the channels whereby functional and personal income distribution impact growth. The growth - inequality relationship can be negative or positive, depending on...

This essay develops a theory of the evolution of international income levels. In particular, it augments the Hansen-Prescott theory of economic development with the Parente-Prescott theory of relative efficiencies and shows that the unified theory accounts for the evolution of international...

I comment on the controversy around Garrison's secular growth, with special emphasis in Murphy's contribution in this issue. I also argue that further research on this area should focus in formally connecting Garrison's model with neoclassical growth theory

This paper addresses the limitations of Modern Money Theory (MMT) as a guide to development policy. We explore two central questions on this topic: whether MMT policies 1) ought to be implemented in low- and middle-income economies and 2) can be implemented. In relation to the first question, we...

We present a class of convex endogenous growth models and analyze their performance in terms of both growth and business cycle criteria. The models we study have close analogs in the real business cycle literature. We interpret the exogenous growth rate of productivity as an endogenous growth...

This paper presents a tractable model of endogenous production networks with fixed costs associated with the formation of links between firms. The model consists of a finite number of firm types producing differentiated products. Each firm is characterized by firm-specific parameters describing...
