2 Can a recession be the result of impovireshment? In most equilibrium models impoverishment, or in general the desire to save more, induces agents to work harder: an expansion. This project: 1 We build a quantitative model where a contraction in demand (say, because of a shock to financial intermediation or sheer impoverishment) generates a recession. We describe what does it take for such recession to occur. 2 In addition, in our model a reduction in consumption decreases measured TFP even though the technology is unchanged. This channel greatly contributes to the recession. Solow residual Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 2 / 32

4 What are major detonants for crisis in small countries? 1 Productivity/endowment shocks. (Many papers, Backus, Kehoe, and Kydland (1992) RBC, Conesa and Kehoe (2011) with governments facing debt crisis.) 2 Interest rate risk. (Neumayer and Perri (2005)). 3 Financial Shocks that affect firms Some are based on missallocation of investments (Bernanke and Gertler (1989) and others)). Others require insufficient assets within a country (Mendoza (2010)). 4 Financial Shocks that affect households and reduce their consumption Midrigan and Philippon (2011) explore the role that less liquidity has in shaping recessions. Wage and labor rigidity generate recessions. Guerrieri and Lorenzoni (2009), Macera (2012) Mian and Sufi (2012) report that in the current US recession, employment in nontradables drops more where household balance sheet suffers more. Not so for tradables. Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 4 / 32
5 Our paper We complement the view that it is household consumption that triggers a recession, but it is not liquidity difficulties and wage rigidity, (Midrigan and Philippon (2011)), or the zero bound of the interest rate and fixed prices (Guerrieri and Lorenzoni (2009), Eggertsson and Krugman (2011)), although fixed prices and wages surely aggravate recessions. We build a model where the desire to save triggers a recession because it is difficult to reallocate resources from nontradables to tradables or in general from consumption to investment. The recession is amplified by the fact that consumption affects productivity. The recession displays the paradox of thrift.

6 Ingredients 1 Exporting more is feasible but hard. It takes time to reallocate the economy to export more. (Tradables and Nontradables). Closed Economy version 2 Labor markets are not competitive. We pose Mortensen-Pissarides determination of labor market so the static Euler equation of the household does not operate directly, although it does to some extent. We also explore the role of fixed wages. These are the only really necessary ingredients. Our contribution is to pose another channel that makes the outcome easier (i.e. smaller shocks for the same outcome): 3 Reductions in Demand (i.e. consumption expenditures)induce productivity decreases. An extension of Bai, Ríos-Rull, and Storesletten (2011). Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 6 / 32
7 The environment: Consumers within a period Households value varieties of nontradables: [ IN ] 1 ρ ρ 0 cni di Under equal consumption of each variety c N I ρ N = [ IN ] 1 ρ ρ 0 cni di Households also like tradables that combine through a standard (Armington) aggregator with nontradables and dislike work and search for goods yielding u [ c(c N I ρ N, c T ), d, n ]. Households have to search for varieties, its number is a choice. I N = d Ψ d (Q g ) Ψ d (Q g ) Probability (per search unit) of finding a variety. Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 7 / 32
8 The environment: Production Firms post prices before the location is filled. Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 8 / 32 Two sectors that we call tradables, & nontradables, small open economy: fixed r. We include in tradables two items normally deemed to be nontradables: Housing Construction and Structures The tradable sector has a measure one of firms. There are adjustment costs to both capital and labor, and its output is used for exports, investment, and (part of) consumption. F T (k, n, l) may have decreasing returns. The nontradable sector consists of a measure one of firms each one producing a different variety. Each firm/variety has a measure one of locations, each location has its own production function F N (k, n). Locations may or may not be filled (get a customer). They produce only for consumption.
9 Search Goods markets for nontradables. There is a large number of varieties. Agents need to search to find varieties. Random search. There is a CRS matching function Ψ(1, D). Market tightness is Q g = 1 D. The probability that a shopper finds a firm-variety: Ψ d (Q g ) = Ψ D The probability that a firm finds a shopper is the measure of filled locations or of consumers buying the good: Ψ f (Q g ) = Ψ 1 = I N. Total sales of nontradables in units of the tradable good that is the numeraire p I N c N = Ψ f (Q g ) F N (k, n) p Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 9 / 32

Job finding probability Φ e (Q e ) Vacancy filling probability Φ f (Q e ) Exogenous job destruction at rate λ Wages (we explore various mechanisms) Nash bargaining Complete rigidity.

Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 16 / 32
17 Strategy We calibrate this economy to look like a modern economy. We study recessions made up of 1% reductions in output generated by 1 A (relatively) persistent increase to the discount rate β. 2 A destruction of wealth (net foreign asset position.) Note that the effects are the opposite to those in the standard growth model. These shocks are a stand in for whatever deteriorates the financial system. Possibly a combination of the two. We then explore the properties of the recession generated. Huo & Ríos-Rull (UMN, Mpls Fed, CAERP) Engineering a Paradox of Thrift Recession October 9, OSU, Econ 17 / 32
18 First Experiment: Persistent shock to discount factor Assume β t = βe θb t the shock to the discount factor follows an AR(1) process: log θ b t = ρ b log θ b t 1 + ε t, ε t N(0, σ b ) We then pose an initial value for ε 0 to reduce output 1%. The value of ρ b is set equals to Advantage: That induces a desire to increase saving temporarily and later to increase consumption. It makes it similar to a financial shock that increases the wealth to income target of the households. Disadvantage. If taken literally, it is silly, but we will not take it literally.

19 More details about the experiments Output in terms of the tradable goods is: Y = p Ψ f (Q g )F N (K N, N N ) + F T (K T, N T ) Real output, Y is in base year prices (Use steady state, p instead of current p). Two wage protocols: Nash bargaining and complete rigidity 1 Standard Nash wage bargaining: A larger shock is needed. Nontradable firms decrease employment and vacancies but tradable firms increase employment and vacancies. 2 Completely rigid wage: Employment and vacancies drop more. Tradable firms increase employment and vacancies only because the vacancy filling rate is higher.

25 Results: I. Shock to patience, households increase savings We look for shocks to β, that follows an AR(1) with.95 persistence that induces an increased desire to save and that generates a 1% output drop in various economies: 1 Baseline economy: wages determined via Nash bargaining and relatively flexible tradable sector (tradable sector expands by 5%). 2 Baseline economy with high adjustment cost in tradable sector: Figures Wages determined via Nash bargaining and very rigid tradable sector. (tradable sector expands by 1%). 3 Baseline economy with fixed wage rate: Figures same dynamic parameters as the baseline economy but with fixed wage rate. 4 Baseline economy without goods market frictions: Figures same dynamic parameters as the baseline economy but without shopping.

Yes Figures Without the contribution of shopping to productivity, the required size of the shock to generate a 1% drop in output is much larger. This is the main contribution of the paper. *Recover time is measured by the duration of employment below the trend.
27 Properties of Shocks to β A recession can be triggered by a desired to save which generates (temporarily) the paradox of thrift. After consumers cut their consumption: Output, consumption, investment and employment decrease. Prices for nontradables and wage rate (if set by bargarning) decrease. Technology is unchanged, but measured Solow residual decreases. It becomes more difficult for the nontradable firms to find a shopper. Tradable sector with decreasing returns to scale expands. The extent of the recessions depend on the rigidity of prices and the flexibility of factor reallocation.

29 Properties of Shocks to wealth B A permanent output and consumption drop can be triggered by a loss of wealth. Mild permanent reduction in employment There is a permanent deterioration of relative prices. Technology is unchanged, but measured Solow residual decreases. It becomes more difficult for the nontradable firms to find a shopper. The extent of the recessions depend on the rigidity of prices and the flexibility of factor reallocation.

31 Conclusions and Summary 1 We have developed a theory of how a desire to save generates a recession and via the paradox of thrift, a temporal reduction of wealth. 2 We have found that recessions can be the result of a desire to increase savings due to some financial mishap. The crucial ingredients are: Limited drop in interest rates. The more rigid the economy (prices, wages, sector reallocation), the worse the recessions. The shopping structure allow the shocks to be smaller than more standard models with similar ingredients (small open economy, rigid wages, Mortensen-Pissarides). All these are important departures from the standard model with productivity shocks (either new keynesian or neoclassical).

33 A Theory of Household Financial Distress and Savings I Imagine that the household has to use financial services to provide insurance to its non-working members. The total net transfer of resources to non-working members is subject to a financial cost ψ per unit transferred. There are shocks to ψ. Assuming the working and non-working members must exert the same shopping effort, but the level of consumption could be different for the two groups. Nontradable firms catter some of its locations for the employed and some for the unemploeyed.

37 A Theory of Household Financial Distress and Savings II Imagine that the household has to use financial services to provide insurance to its non working members. The total net transfer of resources to non-working members is sublect to a financial cost ψ per unit transferred. There are shocks to ψ. In this world there will be specialization: there is enough of a competitive search structure to differentiate goods by markets. Consequently, the unemployed household members will buy cheaper and harder-to-find non-tradable goods.
