In this paper, I study how an increase in the use of new work practices that involve multi-tasking has affected the returns to experience.  If each task in a job has a concave learning curve, then increasing the number of tasks may increase the returns to experience.  Using the Panel Study of...

We develop a model of endogenous skill-biased technical change in developing countries.  The model reconciles wildly dispersed existing estimates of the elasticity of substitution between more and less educated workers.  It also produces an estimating equation for the elasticity, which allow...

Schooling has been shown to provide substantial externality benefits by increasing farm output and shifting the production frontier outwards. This paper investigates the role of schooling at the household- and site-levels in the adoption and diffusion of agricultural innovations in rural...

Using data from a randomized control trail in Sri Lanka, this paper explores whether cash and in-kind grants helped microenterprises approach the productivity level of SMEs.  The paper first estimates production functions and subsequently treatment effects on TFP levels.  Most significantly,...

We run a novel field experiment to link managers of African manufacturing firms.  The experiment features exogenous link formation, exogenous seeding of information and exogenous assignment to treatment and placebo.  We study the impact of the experiment on firm business practices outside of...

This paper builds a dynamic stochastic general equilibrium (DSGE) model of endogenous growth that is capable of generating substantial degrees of endogenous persistence in productivity.  When products go out of patent protection, the rush of entry into their production destroys incentives for...

Much has been written on the determinants of input and technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well...

Information technology, like the telephone, influences market access; this paper answers the question about a reverse effect, does market access affect information technology, in particular its adoption?  Using the introduction of the telephone in Bavaria, I demonstrate with a rank, order and...

A large literature describes how local risk sharing networks can help individuals smooth consumption in the face of idiosyncratic economic shocks.  However, when an entire community faces a large covariate shock, and when the transaction costs of transfers are high, these risk sharing networks...

In this paper we explore whether low rates of sustained technology use can be explained by heterogeneity in returns to adoption.  To do so we evaluate impacts of the Cocoa Abrabopa Association, which provided a package of fertilizer and other inputs on credit to cocoa farmers in Ghana.  High...
