Determinants of Agricultural Technology adoption: the case of improved groundnut varieties in Malawi AgEcon
Simtowe, Franklin; Asfaw, Solomon; Diagne, Aliou; Shiferaw, Bekele A..
This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the...

Determinants of Moral hazard in Microfinance: Empirical Evidence from Joint Liability Lending Schemes in Malawi AgEcon
Simtowe, Franklin; Zeller, Manfred; Phiri, Alexander.
Moral hazard is widely reported as a problem in credit and insurance markets, mainly arising from information asymmetry. Although theorists have attempted to explain the success of Joint Liability Lending (JLL) schemes in mitigating moral hazard, empirical studies are rare. This paper investigates the determinants of moral hazard among JLL schemes from Malawi, using group level data from 99 farm and non-farm credit groups. Results reveal that peer selection, peer monitoring, peer pressure, dynamic incentives and variables capturing the extent of matching problems explain most of the variation in the incidence of moral hazard among credit groups. The implications are that Joint Liability Lending institutions will continue to rely on social cohesion and...

Estimation of Actual and potential adoption rates and determinants of a new technology not universally known in the population: The case of NERICA rice varieties in Guinea AgEcon
Diagne, Aliou; Sogbossi, Marie-Josee; Simtowe, Franklin; Diawara, Sekou; Diallo, Abdoulaye Sadio; Barry, Alpha Bacar.
The NERICA (New Rice for Africa) rice varieties, developed by the Africa Rice Center during the 1990s, are providing hopes for raising the productivity of upland rice farmers in Africa because of their reported high yield potential and adaptability to the African conditions. The varieties are new and not widely disseminated in farming communities and there is lot of interest in the donor community in knowing their potential for widespread adoption across sub-Saharan Africa (SSA). However, when a technology is new and the target population is not universally exposed it, the observed sample adoption rate and classical models of adoption widely used in adoption studies does not inform reliably on its potential adoption and constraint to it in the full...

EXTERNAL SHOCKS AND DOMESTIC POVERTY ALLEVIATION: SIMULATIONS WITH A CGE MODEL OF MALAWI AgEcon
Lofgren, Hans; Chulu, Osten; Sichinga, Osky; Simtowe, Franklin; Tchale, Hardwick; Teska, Ralph; Wobst, Peter.
Two sets of issues loom large on the economic horizon of Malawi: poverty alleviation and the country’s vulnerability to shocks emanating from the outside world. In this paper, simulations with a Computable General Equilibrium (CGE) model of Malawi are used to analyze aspects of these issues. The primary database that is used is a 1998 Social Accounting Matrix (SAM) for Malawi which in part is based on the recently published Malawian Integrated Household Survey (IHS) 1997-98. The simulations explore the effects of external shocks and domestic policy changes aimed at poverty alleviation. The external shocks reflect episodes to which Malawi’s economy has been exposed in recent times: changes in the international prices of tobacco and petroleum products and...

Improved Legume Seed Demand Systems in Central Malawi: What Do Farmers' Seed Expenditures Say about Their Preferences? AgEcon
Kankwamba, Henry; Mangisoni, Julius H.; Simtowe, Franklin; Mausch, Kai; Siambi, Moses.
The overall objective of this paper is to assess the demand for improved groundnut, bean, and soybean seed in central Malawi. Specifically, it examines how smallholder farmers respond to changes in market prices of improved legume seed. It also assesses factors that affect the decision to participate in improved seed technology transfer. Considering four commodities namely groundnuts, beans, soybeans and maize, a staple food, the paper estimates a multivariate probit and a linear approximate of the Almost Ideal Demand System (LA/AIDS) using cross section data collected by ICRISAT in 2010. Uncompensated price and expenditure elasticities are reported for the LA/AIDS model. The paper finds high own price elasticities in all four commodities considered. It...

The Impact of Access to Credit on the Adoption of hybrid maize in Malawi: An Empirical test of an Agricultural Household Model under credit market failure AgEcon
Simtowe, Franklin; Zeller, Manfred.
Guided by the frame work of a household model under credit market failure, this paper aims at investigating the impact of access to credit on the adoption of hybrid maize among households that vary in their credit constraints. The data used in the study is from Malawi collected by the International Food Policy Research Institute (IFPRI).Using the direct elicitation approach; households are classified into constrained and unconstrained regimes. The impact of access to credit is estimated using a switching regression in a Double-Hurdle model. Results reveal that while access to credit increases adoption among credit constrained households, it has no effect among unconstrained households. Results also show that factors that affect adoption among credit...

The Impact of Agricultural Technology Adoption on Poverty: The case of NERICA rice varieties in Benin AgEcon
Adekambi, Souleimane Adeyemi; Diagne, Aliou; Simtowe, Franklin; Biaou, Gauthier.
This study examines the relationship between agricultural technology adoption and poverty with a focus on New Rice varieties for Africa (NERICA). The NERICAs are a group of rice varieties developed by the Africa Rice Centre during the 1990s, resulting from the inter-specific crosses between the Oryza sativa high yielding rice species from Asia and the locally adapted and multiple-stress resistant Oryza glaberrima African rice species. They are believed to provide great hope for African agriculture. Introduced in Benin in 1998, there has been no published analysis on the impact of their adoption by farmers. The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Local Average Treatment Effect (LATE) of NERICA...

The Impact of credit constraints on the adoption of hybrid maize in Malawi AgEcon
Simtowe, Franklin; Zeller, Manfred; Diagne, Aliou.
The paper investigates the impact of credit constraints on the adoption of hybrid maize among rural households in Malawi using the treatment-effects model. Results reveal that after effectively correcting for endogeneity, credit constraints have a reducing effect on the size of land allocated to hybrid maize. Farmers with larger land holdings allocate more land to hybrid maize while older farmers allocate less land to hybrid maize. These findings suggest that there is scope for increasing the cultivation of hybrid maize in Malawi if credit is targeted at younger farmers that are credit-constrained.
