This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...

Taxation theory rarely takes entrepreneurship into consideration. We discuss how this omission affects conclusions derived from standard models of capital taxation when applied to entrepreneurial income. Some of the defining features of entrepreneurship often omitted by standard capital taxation...

This paper explores the relationship between openness to trade, immigration, and income per person across countries. To address endogeneity concerns we extend the instrumental-variables strategy introduced by Frankel and Romer (1999). We build predictors of openness to immigration and to trade...

Based on the advance-retreat course model, a growth model under environmental pressure, this paper builds an economic growth model that focuses on the aggregation of capital and innovation with environmental pressure. Importantly, the paper presents methods for computing the optimal quantity of...

Big data technologies change the way in which data and human labor combine to create knowledge. Is this a modest technological advance or a transformation of our basic economic processes? Using hiring and wage data from the financial sector, we estimate firms' data stocks and the shape of their...

This paper explores the relationship between product innovation and consumption inequality. We employ a modified version of the agent-based macroeconomic model in Georges (2011, 2015). A rise in rents accruing to salaried workers can shift both production and R&D spending toward products...

We present a theoretical argument to identify the conditions under which a firm prefers to invest in factor saving innovations rather than neutral innovations. We prove that incentives to invest in factor saving innovations positively depend on i) total factor productivity and ii) the scarcity...

Based on a general growth model, this paper finds that the steady-state direction of technological progress is determined by the scale return of the production function and the relative factor supply elasticities. A specific version of that model extends Acemoglu (2002) to provide the underlying...
