This study examined the impact of improved rice varieties adoption on rice productivity and farming households’ welfare in Nigeria using a cross sectional data of 481 rice farmers drawn from three states to represent the major rice producing ecologies (Irrigated, upland and lowland) in Nigeria. Access to seed was found to be one of the significant determinants of adoption. Poverty incidence was...

We examine the impact of incomplete risk-sharing on growth and welfare. The source of market incompleteness in our economy is private information: a household’s idiosyncratic productivity shock is not observable by others. Risk-sharing between households occurs through long-term contracts with intermediaries. We ...nd that incomplete risk-sharing tends to reduce the rate of growth relative to t...

In this paper, we measure the welfare costs/gains associated with financial market incompleteness in a monetary union. To do this, we build on a two-country model of a monetary union with sticky prices subject to asymmetric productivity shocks. For most plausible values of price stickiness, we show that asymmetric shocks under incomplete financial markets give rise to a lower volatility of nati...

This paper analyses the role played by vertical linkages on effects of trade liberalization technology upgrading, average productivity, and welfare in a model with heterogeneous firms. We find that strength shapes produces firms’ survival upgrading decisions, having an impact productivity economy, ultimately, welfare. Our calibration results show linkages, their interaction magnify

Gutenberg’s printing press was the great revolution in Renaissance information technology. Economists have struggled to identify its impact in data on productivity, output, or wages. This paper documents the welfare impact of the technology by exploiting data on the price and consumption of books in England between the late 1400s and 1700. I find that the welfare impact of the printed book was ...

this paper examines the effects of agricultural land productivity improvement on the economy of iran assuming that the domestic and international trade liberalizations will open up the opportunities to expand market access. a 25-sector computable general equi-librium model was developed to simulate the effects of this policy. the simulation results indicate that enhancing agricultural land prod...

EPTD Discussion Papers contain preliminary material and research results, and are circulated prior to a full peer review in order to stimulate discussion and critical comment. It is expected that most Discussion Papers will eventually be published in some other form, and that their content may also be revised. ABSTRACT This paper investigates the patterns and determinants of change in livelihoo...
