July 2018Positively Aware? Conflicting Expert Reviews and Demand for Medical Treatment
with Nicholas W. Papageorge, Shaiza Qayyum: w24820
We study the impact of expert reviews on the demand for HIV treatments. A novel feature of our study is that we observe two reviews for each HIV drug and focus attention on consumer responses when experts disagree. Reviews are provided by both a doctor and an activist in the HIV lifestyle magazine Positively Aware, which we merge with detailed panel data on HIV-positive men’s treatment consumption and health outcomes. To establish a causal relationship between reviews and demand, we exploit the arrival of new drugs over time, which provides arguably random variation in reviews of existing drugs. We find that when doctors and activists agree, positive reviews increase demand for HIV drugs. However, doctors and activists frequently disagree, most often over treatments that are effective, but...
September 2007Realizing the Gains From Trade: Export Crops, Marketing Costs, and Poverty
with Irene Brambilla, Guido Porto: w13395
This paper explores the role of export costs in the process of poverty reduction in rural Africa. We claim that the marketing costs that emerge when the commercialization of export crops requires intermediaries can lead to lower participation into export cropping and, thus, to higher poverty. We test the model using data from the Uganda National Household Survey. We show that: i) farmers living in villages with fewer outlets for sales of agricultural exports are likely to be poorer than farmers residing in market-endowed villages; ii) market availability leads to increased household participation in export cropping (coffee, tea, cotton, fruits); iii) households engaged in export cropping are less likely to be poor than subsistence-based households. We conclude that the availability of mark...

March 2005Globalization and Complementary Policies: Poverty Impacts in Rural Zambia
with Guido Porto: w11175
In this paper, we have two main objectives: to investigate the links between globalization and poverty observed in Zambia during the 1990s, and to explore the poverty impacts of non-traditional export growth. We look at consumption and income effects separately. On the consumption side, we study the maize marketing reforms and the elimination of maize subsidies. We find that complementary policies matter: the introduction of competition policies at the milling industry acted as a cushion that benefited consumers but the restriction on maize imports by small-scale mills hurt them. On the income side, we study agricultural export growth to estimate income gains from international trade. The gains are associated with market agriculture activities (such as growing cotton, tobacco, hybrid maize...
