i am sorry, there is someone else booked all my slides and books. But I have another Chinese classmate of Economics and Finance of Aging. She is also going to sell her books and documents. Do you want hers? The Econometric book she sell is exactly the same as mine, and the price is 6 euro. There is another book for investment analysis II, which is a selective course, and the price of that book is 7 euro. She also wnats to sell all her slides with price 10 euro totally. If you want any of them, you can just contact with me. Wish you good luck in your future studying in Tilburg!
