Summary & outline Preliminary study of HIV/AIDS morbidity & mortality impacts on rural economies in Malawi, direct & indirect effects (through labour & non-tradable markets) • Core questions: impact of HIV/AIDS epidemic on wages? • if it depresses labour demands more than it contracts labour supply • lower wage rates damage livelihoods of all poor households. • labour saving enterprises & technologies could be disastrous for the healthy poor. • Household livelihood models investigate direct impacts of HIV/AIDS morbidity and mortality. • Aggregate partial equilibrium informal rural economy model investigates direct & indirect impacts of HIV/AIDS morbidity & mortality • Conclusions
RURAL ECONOMY Different responses by different households? HIV/AIDS Systemic local market & environment impacts etc? EXTERNAL ENVIRONMENT Different impacts on different households? Disaggregated analysis of impacts of HIV/AIDS • Systemic impacts of HIV/AIDS not easy to study • Wages & food prices particularly important, affect • households directly affected by HIV/AIDS • the poor, even without any sick or deceased members.
Wage impacts: alternative hypotheses • Contractions in labour force raise wages? • Market labour demand falls, supply increases: wages fall? • poor affected households hire out more labour to meet urgent cash needs • reduced demand for unskilled on-farm labour among less poor affected households • unable to finance labour hire from savings, semi-skilled or skilled employment, remittances • reductions in family labour & capital shortages cause shift out of labour demanding cash crops • non farm labour demand falls as local demand for goods & services is reduced by depressed incomes • increases in poverty incidence & severity increase unskilled labour supply into the market
Methodology: Investigate direct and indirect impacts • Household typology • Household livelihood models • Aggregation of household models to partial equilibrium ‘informal rural economy model’ • HIV/AIDS morbidity & mortality scenarios • Impacts • household welfare & activities • wages
Non-Linear Programming Livelihood model • 7 household types in major zone, standard model structure, varying resource endowments • Seasonality: in prices, labour, capital (cash, maize), activity demands for labour/ inputs, (4 periods) • Resources: initial cash and maize, land, seasonal labour (skill classes) • Activities: various crops & technologies (subsistence, cash), unskilled & semi-skilled non-farm activities • Imperfect input & output markets/ transaction costs: price wedges • Risks: consumer & producer price risk • LES calorie, cash & leisure consumption by period
Morbidity/ mortality scenarios Household impacts • Morbidity: varying % loss of 1 unskilled adult female or 1 skilled adult male labour & increase of 1600MK expenditure • Mortality: Loss of unskilled female or skilled male labour & consumption, MK800 pre-season cash reduction IRE ‘Sick’ households: 40% labour loss & expenditure increase
Wage impacts: alternative hypotheses Market labour demand falls, supply increases: wages fall? • poor affected households hire out more labour to meet urgent cash needs NO • reduced demand for unskilled on farm labour among less poor affected households YES • unable to finance labour hire from savings, semi-skilled or skilled employment, remittances YES • reductions in family labour & capital shortages cause shift out of labour demanding cash crops YES Overall farm labour surplus falls slightly • non farm labour demand falls as local demand for goods & services is reduced by depressed incomes ??? • increases in poverty incidence & severity increase unskilled labour supply into the market ???
Discussion • Hypotheses 2 & 3 supported: HIV/AIDS can lead to • reduced demand for unskilled on farm labour among less poor affected households as • unable to finance labour hire • shifting out of labour demanding cash crops • non farm labour demand falls as local demand for goods & services is reduced by depressed incomes • Overall loosening of labour market can cause wage falls • healthy poor suffer • increased inequity • labour saving technology impacts? • Food price impacts - & knock on effects ? • Validity of the model & scenarios? • Further research? • Immediate policy? • High risk factors & areas? Diversity? • Policy responses?
