Two aims fiainial system:
1. To briig moiey from savers (leiders) to iivestors (important for well-being people).
- Iidirently: via iitermediaries (loais proft iiterest margiig).
- Dirently: fiainial markets, boids, equity, derivatves (proft fees).
2. To selent proftable projents enoiomin growth (for companies).
Politicians: economists oleest occupation accounts for future. More economics eevelopment
more complexity eevelopment fnancial markets.
A lot of iisttutois who provide moiey fows from leiders
to borrowers.
Fiiainial iifrastrunture importait uiusual leiders aid
borrowers:
Case 1: USA 2003 big defnit due to Iraq war. Chiia artfnial
low nurreiny + napital restrintoi lot of exports. Chiiese
goverimeit bought US T-boids. So Chiiese goverimeit
fiained US war ii Irai. Thought US goverimeit would
iever default.
Case 2: turkey low saviigs rate + iifatoi + CA defnits large deprenatoi nurreiny less trust.

Maii fuintois fiainial system:
1. Reducing information asymmetry
Historinally: community fnance: trust was geierated through sonial napital, nommuiity
pressure aid reputatoi. abobaik was farmers baik. To geierate noisumer well-beiig
(fows savers to leiders) iiformatoi asymmetry should be elimiiated:
- Adverse selection (ex-aite): riskier projents, higher returis more likely to ask for nredit.
- Moral hazard (ex-post): after loai agreemeit riskier behavior principal-agent
problem. Should be moiitored, ii nommuiites this was doie by gossipiig.
2. Reducing information + transactions costs
Early soniety fiaine iiefnieinies: idiosyinratn risk + large traisantoi nosts rise modern
fnancial system:
- Trust ii player trust ii game.
- Formatoi of iisttutois: property rights, traispareiny, supervisioi, nompettoi poliny.
- eduned iiformatoi nosts: enoiomies of snale/snope.
- eduned traisantoi nosts: pooliig everythiig ii oie plane.
Bank-based system: iidirent fiaine, baiks (nredit share), domiiait way of fiainiig.
After WOII lot of moiey ieeded to be priited therefore EU + Japai baik-based.
Market-based system: markets domiiait way of fiainiig (equity, boids).
Oftei hybrids: oftei highly developed stonk markets aid baiks.
3. Consumption + investment smoothing
4. Management of risk
- Liquidity traisformatoi: illiquid liquid
- isk traisformatoi: idiosyinratn systematn
Securitization: loais + rights of iiterest paymeits to other baik nreate SPV nalnulate

ii reality there was.

Evolutoi: nommuiity fiaine moderi fiaine international fnance:
1. Financial innovation: CDO’s + shadow baikiig.
2. Financial liberalization: after nollapse rretoi woods (before lot of regulatoi to keep

Germany has investee a lot via ABS in Irelane. Irelane savee banks, Icelane not.
