 So I have a question directed to Florence and Baptiste. So what's really crucial in the matching estimator that you implement for the causal inference that you want to draw is to be sure that you include the parameters that potentially unobserve parameters that would guide on the one hand the propensity to save, on the other hand the propensity to remit, potentially also. So you don't have a lot of observable variables to control for, but I was wondering to which extent you could include observable for migratory status. I could not really understand how, well, to which extent the sample that you have is a selected sample already that would make that, even the people that would take outside of the orange users are already a bit comparable in terms of migration or not, but I guess that the position, whether they are migrants or not would strongly influence the propensity to remit. Family structure, if you think of the contribution of Marie, probably the family structure and the extent, and the magnitude of the shape could also be a variable that would be interesting to control for. And I could not, well, what's striking in your propensity to score estimation is that it seems that the orange users are poorer than the rest of your sample. So it's a bit disturbing. So is it the case that orange are specifically focused on the poorest populations? Or else is it the case that you are here capturing the fact that you have people who are migrants who have individualised earnings and when you have... So perhaps also the extent to which earnings are individualised or not could influence the propensity to use them and then to transfer to others. So I think there are many, many other variables you could think of, but I think that those ones could be... Serena? So I have a question for Florence and one for Marie. So for Florence, I wasn't entirely sure because I think from the presentation it came out that there was nothing on deposits. So the rate of deposits is an increase, but then in the end you discuss that this may be related to precautionary savings in some way. So I was just wondering if you could kind of go deep... because I'm working on something similar. So if you could go deeper into the precautionary savings motive just because it wasn't clear. And then under the remittances, you said that you haven't found anything on the sum transferred but just on the frequency, correct? So have you tried perhaps and divide the sample in terms of the... well, the tersiles or whatever of the income distribution to see if it's the poorer they receive more frequently because there may be an issue of them having an urgency to get... because if it's not the sum but just the frequency then that may be something. So for Marie, it was just something on the endogeneity. You know, the number of siblings is fine, I can understand it. But the social mobility measure, I was wondering on what grounds do you think that that's not endogenous to the amount of savings? Yes, Han. And then Mikhail. Just a quick... Han from UNewider. I just wanted to add on to that point about the nature of the remittances in terms of who the... the treatment group is if you just anecdotally, if you look at who's remitting money, it's the foreign workers standing outside a remittance company on their payday. And I believe you have that in your data, whether or not the respondent is a native of the city that I think could be a proxy for whether or not it's a migrant or a native. So I thought that was what I was thinking about as you were presenting as well. The nature of the remittances it's almost as important as the sum that's remitted and the frequency. Thanks. Mikhail. That's on the paper by Florence. One of the selection effects are potentially so strong here because even how you construct your comparison that you say, okay, we compare those who have recently made use of it to those who have not made use of it. So, well, of course it's not at all surprising to see that they use it more frequently and that they may even save a bit more. So that's really what you find. But, I mean, what can we really draw from this and say, can you say a bit more, maybe how others are saving? So if you say this seems to be cheaper lower transaction costs so they can also use it more frequently. I mean, I tried to compare it with other interventions and you can think of, I don't know, you distribute malaria bed nets and then you look at usage. But, you know, given that you have this exogenous distribution then there's really the question is there an uptake? But here this question of uptake isn't really there because it's so actively they decided to use it so I wonder a bit how far you can push the conclusion. Thank you. Thank you for all these questions. I'm going to try to answer you with my poor English. I'm very sorry. About Denis's question. You're right. We made a choice. We know that to match people we can choose to take into account observable characteristics or unobservable using after instrumental variables methodology. Well, we thought that between our two groups of populations there are enough differences, observable differences to implement the matching methodology. We implement and via the paper Wilcoxon ranking test which confirmed that about the number of remittances sent and received our estimation were robust. So we agree that with the fact that it's possible that our two sub-population presents differences in terms of unobservable characteristics but to our knowledge it isn't possible to correct at the same time both differences. So we made this choice with its limits. You're right too. We have a few vectors of significant variables in our probit estimation. But we think it's sufficient because when we implement balancing tests and over-test about quality of our matching process the results are quite good. So we think that these variables are enough. About migration, I haven't with me the questioner but unfortunately I think that we haven't any question. We know where people are born in Thananarive or outside but we don't know if it's in foreign country or in Madagascar. So we can't control by the migrations. It's true that things will be different if we have many migrants in our populations and in our orange money users. But remember that when we implement our survey orange money did not permit to make international remittances. So if we have migrants they can't use these mobile banking services to... Ah, yes. But we control by the place of birth which is a significant variable in the estimation to be an orange money user. OK? No, but we don't know. We don't know. Yes, we don't know why he is coming in Thananarive. Why orange money users are poorer than non-users? We agree it's a result a bit strange but we explain it by the fact that we have a population composed of only orange customers and in Thananarive orange customers are more educated and richer than the rest of the population. So we think that the richest of our orange customers have yet access to multiple sort of banks or financial services but the poorest of the orange customers don't have this access so choose to subscribe to these services. About precautionary savings. I don't remember who asked me this question. It's a great idea to divide the distribution to see if it's just the poorer we receive remittances but we have a short sample so I don't know if statistically it will be possible. We can try to make this division. I'm not sure to have to take the good notes. Ah, yes, I had a question about why I say that orange money users make more precautionary savings because we have a question in our survey which is which service you use the most and this service is the deposit service. People make deposits on their orange money account. So we can think that this service is without interest. It isn't saving with interest but it's a kind of precautionary savings. We can think that people put money in their orange money account to keep it in case of shocks. No, we assume. Sorry, sorry. I think it was Michelle. About the nature of remittances, you asked me something. Who is the treatment group? It isn't a question. I'm a little bit stressed. Then you can. Continue a bit on this. Is it really possible to do that? Baptiste, if you want to complete, you want to complete? No, it's okay. That's it, no? I remember. Thank you. Sorry. Thank you, Serena, for your question. So I agree that... I'm not saying any causal impact here. That's what I said at the end. So through the number of savings, there's no decision to save and transfer. For social mobility, I would argue that since I compare former workers with fathers that were farmers or non-farmers, I'm looking at the different co-efficient between one with both former workers and one as a father with a farmer. I'm not saying that the co-efficient should really be taken as granted, but still we still find that switching signs. So for one it's really negative and for the other it's really positive. And if social mobility should bias the estimate, I would say that people who experience social mobility should be even more safe because they have less inheritance than others and which so they should be even more saving while we find negative effects. I don't know if you can answer your question. I would like to continue with this, to make more clear. Given that you look at these immediate outcomes like making use of it, saving more, making more transfers, it is in fact very close to the process of this taker, which is emotions. So maybe to make it a bit more interesting we should go a bit further. To look at other outcomes, that's maybe less obvious that we may see a difference. So what do you mean by that? What do you mean? Because they save more often do they have higher investment or are they spending more on education or are they going a bit further because of change. If you stop there, you make it more something because you want to transfer, and I think this is actually kind of being even more, it's very much, I think in a bit more ways it's hard to sell it and the more it's okay, what does it mean to tell you? Go a bit further and show some of these other impacts and this becomes ultimately less a problem maybe. Yes, yes, yes. First of all, we must actually make another one with the same population and remember how to do this. Arrange my sentences in the book in September and September 10 and we made the survey only for two days after that. So in our mind we try to just focus on financial and in our mind we think that it's quite simple to use the transfer sense because it is cheaper because it's safer and without the pros and cons it's anonymous. Okay? So you guys sell your hands but we think that to change deeply your financial if you focus on sales if you focus on some of the things that need to be done first more quickly, I think this is something that absolutely has to be learned by the new process. This is why we call this paper learning to work if you want to work you need to you need to be able to trust more confidence in this that you like. The role of that you need to have another knowledge to have perhaps more variables and so on. We have many, many testers and we made lots of your estimations with very different variables cross-vibes and so on and this is the best estimations Thank you, Baptiste. We can continue the conversation after and we have the final panel in 10 minutes so we invite you to attend and thank you very much for the presenters and for you to come to the session. Thanks.
