Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 1 Financial Intermediation and Liquidity Transformation Main Ideas Banks insure consumers against liquidity shocks. Banks also monitor and supply liquidity to …rms. Lending and Deposit-taking are complementary forms of liquidity creation How do Financial Intermediaries create Liquidity? On the liability side: by issuing securities that can be easily sold On the asset side: through relationship lending Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 2 1) Liquidity transformation with no aggregate risk Diamond and Dybvig (1983) Main Idea: (1) investors may be subject to liquidity shocks which force them to liquidate their investments early, (2) liquidation is ine¢ cient and the market structure is incomplete: no claims contingent on an individual’s liquidity shock can be traded. (3) bank deposit contracts can provide insurance against liquidity shocks, but (4) bank deposit taking exposes banks to the risk of a bank run Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 3 The Model: Three periods: Date 0: - consumers have an endowment of one unit of consumptiongood (wheat) they can save - two investment projects: a storage technology which allows them to transfer the good to future periods at no cost. a long-term illiquid investment which delivers C > 1 units of good at date 2 for one unit invested at date 0. Date 1: - Liquidity shocks are realized. impatient consumers (type 1) consume at date 1. liquidating the long term investment at date 1 generates a return of C < 1 for any unit invested at date 0. Date 2: patient consumers (type 2) consume at date 2.

With a continuum of agents, each with the same probability of facing liquidity shocks, the planner needs such that 1 = x1 (law of large numbers), and C = (1 =) )x2 Bolton Gerzensee (August 7, 2013) The optimal Liquidity Transformation and Crises maximizes ex ante expected utility: max u( 1 ) + (1 )u( C 1 =) PE is such that: u0(xP1 E ) = Cu0(xP2 E ) Compare with autarky solution: u0(x?1) = 1 C 1 0 ? u (x2) 1 C ) 7 Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 8 Deposit Contracts and Banks Suppose that contracts conditional on the identity of the agents hit by a liquidity shock are not feasible. Can we still implement the optimal allocation? Consider a bank o¤ering deposits to agents: If an agent deposits 1 unit in t = 0, this agent can withdraw R1 in t = 1 and R2 in t = 2. deposit withdrawals are served sequentially until the bank runs out of cash suppose agent j wants to withdraw R1 in date 1. She then obtains: R1 0 if R1 Aj otherwise where Aj are the total cash reserves of the bank, after all depositors before j have withdrawn their deposits Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 9 Candidate equilibrium: the bank invests xP1 E in the storage technology and (1 )xP2 E in the long term asset. R1 = xP1 E , R2 = xP2 E Only type 1 depositors withdraw at date 1 a type 2 investor who withdraws at t = 1 gets xP1 E , which can be stored until period 2 a type 2 investor who waits until period 2 gets xP2 E at t = 2. =) Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises a type 2 investor prefers waiting if xP2 E 10 xP1 E , from u0(xP1 E ) = Cu0(xP2 E ) and (u is concave). we observe that xP2 E C xP1 E provided that 1. ) If C < 1, everybody withdraws at date 1 when C 1 only type 1 investors withdraw at date 1, assuming type 2 investors trust the bank the proportion of withdrawals at t = 1 is then exactly and the bank is solvent with probability 1 BUT..... Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 11 even if C 1, there is a second bank-run equilibrium where the bank goes bust at t = 1 : suppose the type 2 investor anticipates that all the other type 2 investors withdraw their deposits then bank is forced to liquidate its long-term investment, generating cash of only A = xP1 E + (1 )xP2 E C =) A is too small to cover all the withdrawals xP1 E Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 12 sequential service =) best response is to withdraw as soon as possible ) Bank run as an (ine¢ cient) equilibrium. Barring a bank-run (through forward induction argument?) banks provide an e¢ cient ‘liquidity transformation service’, which allows consumers to improve on their autarky payo¤s. But, are …nancial intermediaries really needed? Can’t consumers achieve e¢ cient liquidity transformation by trading assets or claims on their future output in a competitive secondary market? Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 13 Market Allocation: Suppose now that there is no bank but there is a bond market at date 1: Agents can trade the consumption good against the promise to receive some quantity of goods at date 2. Denote by r the return on the bond: Suppose an impatient (type 1) investor borrows in the bond market: he will receive C from the long-term investment =) he can borrow C r so that x1 = 1 + C r Patient (type 2) investors lend in the bond market and get x2 = (1 )r + C In equilibrium, must have rx1 = x2: Why? No arbitrage condition!

If they can take short positions then again we have a no arbitrage constraint: x1 = px2 Then, as before, ex-ante utility maximization subject to this constraint is achieved for x1 = 1 and x2 = C Bolton Gerzensee (August 7, 2013) Liquidity Transformation and Crises 20 Bank Runs: Explains only speculative bank runs. Investment returns are certain, so no bad news trigger these runs. Empirically, bank runs are also related to bad fundamentals, like poor performance of the loan portfolio. Allen and Gale (1998) make C a random variable (aggregate shock) Cannot explain coexistence of Banks with a bond market Townsend 1982 and Jacklin 1987 no arbitrage condition: optimal bank deposit contract: R1 = xP1 E , R2 = xP2 E must also satisfy: rR1 = R2 but this implies that R1 = 1 and R2 = C!

THE MODEL I. Basic structure • Four period economy. • 2 types of agents, short and long run investors. • The risky asset is the only source of risk. II. Agents • Short Run Investors (SRs): u (C1, C2, C3) = C1 + C2 + δC3 with 0 < δ < 1 • Long Run Investors (LRs): u (C1, C2, C3) = C1 + C2 + C3 III. Financial markets and investment opportunity sets • Assets: Cash, a “long asset,” and a “risky asset.” • Investment opportunities: We assume that – LRs can invest in cash and in the long asset. – SRs can invest in cash and in the risky asset.

The θ parameter (A) It determines the probability that the risky asset pays early, when the short run investors value it the most. (B) It is also the parameter that determines the severity of the adverse selection problem: • The higher it is the more likely the LR is to find “lemons” in period t = 2. (C) It also determines the supply of the assets at t = 2: • The higher the θ the lower the supply of the assets at t = 2 as more agents, θη, obtain the realization ρ and don’t need to liquidate: II. The δ parameter • δ determines the value of the SR of retaining the asset and carrying it to date t = 3 and it introduces existence and commitment issues. Assumptions • LRs carry cash only if they can deploy it to acquire the risky assets at very advantageous prices. Specifically, ϕ0 (κ) > 1, and thus “cash-in-the-market pricing” obtains: Price of risky asset = Outside Liquidity < Expected discounted payoff Amount of risky assets supplied • SRs do not want to invest in the risky asset in autarchy: They only invest in it if when it does not pay off they can liquidate at attractive prices. λρ + (1 − λ) [θ + (1 − θ) δ] ηρ < 1 • But investing in the risky asset is socially beneficial in that the expected return on the asset is greater than cash. ρ [λ + (1 − λ)η] > 1 The problem of the SRs and the LRs I. The SRs decide • how much inside liquidity to carry, m, and how much to invest in the risky technology, 1 − m • and a liquidation policy in the lower branch of the tree. – Essentially, whether to liquidate at date t = 1, q1, and/or t = 2, q2 II. The LRs decide • how much outside liquidity to carry, M , and how much to invest in the long asset, κ − M • when to step in to acquire assets at firesale prices. – Essentially, whether to jump in the market at date t = 1, Q1, and/or t = 2, Q2.

Definition • A vector of portfolio policies, [m∗, M ∗], • prices, [P1∗, P2∗] and • liquidation, [q1∗, q2∗], and acquisition policies, [Q∗1 , Q∗2 ], such that agents maximize and markets clear. • An equilibrium must also specify the price S1∗ that would obtain in event ω1L for payoffs in period 3 and the price S2∗ for these payoffs that would prevail in period 2. II. Two types of equilibria • Immediate trading equilibrium: Trading occurs at date t = 1 - No adverse selection • Delayed trading equilibrium: Trading occurs at date t = 2 - Adverse selection EQUILIBRIUM UNDER FULL INFORMATION • Under full information the only equilibrium is a delayed trading equilibrium. • Why can’t we support an immediate-trading equilibrium? – The conditions for a putative immediate-trading equilibrium are P1i∗ ≥ θηρ + (1 − θ) P2i∗ and P2i∗ ≥ P1i∗ – This implies P1i∗ ≥ ηρ ⇒ P2i∗ ≥ ηρ e – Given that E[ρ|F 1 ] = ηρ under symmetric information, it follows that the expected return of carrying cash for LRs cannot be greater than one and thus Mi∗ = 0 which implies m∗i = 0 • Under full information a delayed trading equilibrium always exists.

Pc0 P1 – This implies that Pc0 ≥ [λ + (1 − λ) η] ρ, – Given that ϕ0 (κ) > 1 LRs do not bring any capital to the putative instantaneous-trading equilibrium. II. General investment opportunity sets • Are the results affected if we allow SRs to invest in the long run project and LRs to invest in risky projects? • No. – SRs ∗ would not invest in long-run assets if δϕ0 (0) < 1. ∗ If they do, analysis goes through for the proportion of initial funds not invested in the long-run asset (and SRs might sell the long asset to LRs at, for example, t = 2.) – LRs ∗ Cash is a constant returns to scale technology. If SRs are partially invested in risky assets then LRs are invested in cash and long-run assets. ∗ LRs may be holding risky assets when SRs are fully invested in risky assets but provide an inadequate supply of risky assets. III. Cash-in-the-market pricing and Arbitrage Contagion • Cash-in-the-market pricing: Key to support an equilibrium where M ∗ > 0. • Cash-in-the-market pricing and the absence of arbitrage implies that the price of one unit of the long run project payable at date 3 has to be such that LRs are indifferent between holding the long run project and cash at t = 1 and t = 2: – In the immediate-trading equilibrium: ∗ S1i P1i∗ <1 = ηρ and ∗ S2i =1 – In the delayed trading equilibrium (when it exists) ∗ S1d ∗ P1d ≤1 = ηρ and ∗ S2d • This occurs even when: – There are no news about the long run project and – The asset is not subject to distressed sales ∗ P2d (1 − θη) = <1 (1 − θ)ηρ
