This paper presents a simple model of subsidies with export share requirements (ESR) in a heterogeneous firm environment. A two-country general equilibrium version of the model with a single 100% ESR is calibrated using firm-level data from the 2002 wave of the Business Environment and...

Special economic zones, one of the most important instruments of industrial policy in developing countries, often feature export share requirements. That is, firms located in these zones are obliged to export more than a certain stated share of their output to enjoy the wide array of incentives...

This paper studies the export decision of risk-averse firms in a model featuring aggregate uncertainty and no capital markets. Firms seeking to enter the foreign market face a sunk cost as well as a fixed participation cost every period they export. Using a calibrated version of the model, I...

There is growing interest in using messaging to drive prosocial behaviors, which contribute to investment in public goods. The authors worked with a leading nongovernmental organization in Peru to randomize nine different prorecycling messages that were crafted on the basis of best practices,...

This paper investigates the potential of information technology to improve public service delivery and empower citizens. The investigation uses two randomized natural experiments in the renewal of national identification cards by the Bolivian Police. The first experiment arises from the random...

Evidence from historical and epidemiological literatures show that epidemics tend to spread in the population according to a logistic pattern. We conjecture that the impact of new technologies on output follows a pattern of spread not unlike that of typical epidemics. After reaching a critical...

This paper extends Grossman and Helpman’s seminal work (1991), and presents an endogenous growth model where innovations created in a high-tech sector may be assimilated or adapted by a low-tech sector. Applying a simple Heckscher-Ohlin framework, the effects of technological diffusion are...
