<> Both -mvprobit- and -triprobit- are user-written and obtained via -findit-, we should add. Mind the FAQ re user-written material... HTH Martin -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Nyasha Tirivayi Sent: Montag, 30. August 2010 20:14 To: statalist@hsphsun2.harvard.edu Subject: st: mvprobit Hello I am now trying to estimate a model on the effects of a food aid program on labour market dynamics of HIV affected households. Receipt of food aid is also an endogenous variable, while I am also trying to deal with the initial conditions problem. I have panel data from pre-food aid and 6 months after food aid program began. I am also suspecting that this could involve 3 recursive simultanaeous equations as follows: Employment at t = f (foodaid, age, gender, household income, education) Food aid = f (age, gender, education, household income, HIV prevalence in area, household dependency ratio, employment at t-1) Employment at t-1 = f (age, gender, household income, education) I am thinking of using mvprobit or triprobit for transition analysis controlling for initial conditions and the endogeneity of food aid. I am especially interested in doing separate sub-group analysis e.g. looking at the transitions for those who were employed pre-program and those who were unemployed. Would you kindly advise on how best to write my code for people who made transition from unemployment to employment? How do I write the code to specifically estimate the transition to employment conditional on previous emplorment state? Do I include employment at t-1 in the current employment equation as a lagged explanatory variable?
