Financial literacy and its consequences: Evidence from Russia during the financial crisis

The ability of consumers to make informed financial decisions improves their ability to develop sound personal finance. This paper uses a panel data set from Russia, an economy in which household debt has grown at an astounding rate, to examine the importance of financial literacy and its effects on behavior. The paper studies both the financial and real consequences of financial illiteracy. Even though consumer borrowing increased very rapidly in Russia, only 41% of respondents demonstrate an understanding of interest compounding and only 46% can answer a simple question about inflation. Financial literacy is positively related to participation in financial markets and negatively related to the use of informal sources of borrowing. Moreover, individuals with higher financial literacy are significantly less likely to report experiencing a negative income shock during 2009 and have greater availability of unspent income and higher spending capacity. The relationship between financial literacy and availability of unspent income is higher in 2009, suggesting that financial literacy may better equip individuals to deal with macroeconomic shocks.     

Heterogeneous life-cycle profiles, income risk and consumption inequality

Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use Consumer Expenditure Survey (CEX) repeated cross-section data on consumption and income to decompose idiosyncratic changes in income into predictable life-cycle changes, transitory and permanent shocks and estimate the contribution of each to total inequality. Our model fits the joint evolution of consumption and income inequality well and delivers two main results. First, we find that permanent changes in income explain all of the increase in inequality in the 1980s and 1990s. Second, we reconcile this finding with the fact that consumption inequality did not increase much over this period. Our results support the view that many permanent changes in income are predictable for consumers, even if they look unpredictable to the econometrician, consistent with models of heterogeneous income profiles.     

Minimum consumption and transitional dynamics in wealth distribution

This paper investigates quantitatively how initial wealth holding differences across households are propagated through time in a one sector growth model economy. A key feature of the model is that household consumption cannot fall below a positive level each period. The existence of a minimum consumption requirement implies that the Intertemporal Elasticity of Substitution not only differs across households but also changes differently over time. This model is calibrated to match some key aggregate statistics of the U.S. economy. We find that, as in the data, the wealth distribution in our benchmark model economy exhibits a (brief) period of increasing inequality, a short period in which inequality diminishes and a steady level of inequality along the balanced growth path. However, our model illustrates that the evolution of inequality is very sensitive to the length of the transition path. Additionally, our model predicts an upsurge in wealth inequality following the productivity slowdown in the 1970s.     

债务杠杆、财务脆弱性与家庭异质性消费行为

本文通过引入财务脆弱性来描述家庭无法及时或完全履行偿债义务而发生的财务困境,实证分析了债务杠杆对家庭消费的异质性影响。理论机制分析和基于中国家庭金融调查(CHFS)数据的实证研究表明,家庭债务杠杆会提升财务脆弱性,从而弱化跨期消费平滑能力,强化消费预算约束,导致家庭落入“高边际消费倾向、低消费支出水平”的低层次消费路径上。进一步分析发现,对于通过负债投资多套房的家庭而言,高债务杠杆会明显增加不确定冲击下的财务脆弱性,进而对消费产生更大的抑制效应;亲友民间借贷的履约机制相对灵活,可以缓解财务脆弱性对家庭消费的抑制效应;债务杠杆上升引致的财务脆弱性,对耐用消费品支出的压缩效应大于非耐用消费品,对农村家庭消费支出的挤占效应大于城镇家庭。本文的研究为我国“不宜依赖消费金融扩大消费”“规范发展消费信贷”等提供了理论解释,对金融服务促进消费发展具有一定政策启示。     

Household Debt Overhang and Transmission of Monetary Policy

We investigate how the level of household indebtedness affects the monetary transmission mechanism in the U.S. economy. Using state‐dependent local projection methods, we find that the effects of monetary policy are less powerful during periods of high household debt. In particular, the impact of monetary policy shocks is smaller on GDP, consumption, residential investment, house prices, and household debt during a high‐debt state. We then build a partial equilibrium model of borrower households with financial constraints to rationalize these facts. The model points to the weakening of the home equity loan channel as a possible reason for the decline in monetary policy effectiveness when initial debt levels are high.     

Monetary and Fiscal Policy Switching

A growing body of evidence finds that policy reaction functions vary substantially over different periods in the United States. This paper explores how moving to an environment in which monetary and fiscal regimes evolve according to a Markov process can change the impacts of policy shocks. In one regime monetary policy follows the Taylor principle and taxes rise strongly with debt; in another regime the Taylor principle fails to hold and taxes are exogenous. An example shows that a unique bounded non-Ricardian equilibrium exists in this environment. A computational model illustrates that because agents' decision rules embed the probability that policies will change in the future, monetary and tax shocks always produce wealth effects. When it is possible that fiscal policy will be unresponsive to debt at times, active monetary policy (like a Taylor rule) in one regime is not sufficient to insulate the economy against tax shocks in that regime and it can have the unintended consequence of amplifying and propagating the aggregate demand effects of tax shocks. The paper also considers the implications of policy switching for two empirical issues.     

A comprehensive approach to measuring the relation between systemic risk exposure and sovereign debt

Using an integrated model to control for simultaneity, as well as new risk measurement techniques such as Adapted Exposure CoVaR and Marginal Expected Shortfall (MES), we show that the aggregate systemic risk exposure of financial institutions is positively related to sovereign debt yields in European countries in an episodic manner, varying positively with the intensity of the financial crisis facing a particular nation. We find evidence of a simultaneous relation between systemic risk exposure and sovereign debt yields. This suggests that models of sovereign debt yields should also include the systemic risk of a country's financial system in order to avoid potentially important mis-specification errors. We find evidence that systemic risk of a country's financial institutions and the risk of sovereign governments are inter-related and shocks to these domestic linkages are stronger and longer lasting than international risk spillovers. Thus, the channel in which domestic sovereign debt yields can be affected by another nation's sovereign debt is mostly an indirect one in that shocks to a foreign country's government finances are transmitted to that country's financial system which, in turn, can spill over to the domestic financial system and, ultimately, have a destabilizing effect on the domestic sovereign debt market.     

Competitive risk sharing contracts with one-sided commitment

This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex post. In any given period, after having observed her income, the agent can walk away from the contract, while the intermediary cannot, i.e. there is one-sided commitment. We consider the extreme scenario that the agents face no costs to walking away, and can sign up with any competing intermediary without any reputational losses. We demonstrate that not only autarky, but also partial and full insurance can obtain, depending on the relative patience of agents and financial intermediaries. Insurance can be provided because in an equilibrium contract an up-front payment effectively locks in the agent with an intermediary. We then show that our contract economy is equivalent to a consumption-savings economy with one-period Arrow securities and a short-sale constraint, similar to Bulow and Rogoff [1989. Sovereign debt: is to forgive to forget? American Economic Review 79, 43-50]. From this equivalence and our characterization of dynamic contracts it immediately follows that without cost of switching financial intermediaries debt contracts are not sustainable, even though a risk allocation superior to autarky can be achieved.     

The Heterogeneous Responses of Consumption between Poor and Rich to Government Spending Shocks

Government spending shocks have substantially different effects on consumers across the income distribution: consumption increases for the poor whereas it decreases for the rich in response to a rise in government expenditure. I shed light on this issue by incorporating a progressive tax scheme and productive public expenditure into a heterogeneous agent model economy with indivisible labor. The model economy is able to successfully match aggregate and disaggregate effects of government spending shocks on consumption. When the government increases its spending and accompanies it by a rise in tax progressivity, the poor are employed and increase their consumption since after‐tax wage rates increase while the rich decrease their consumption because of a fall in after‐tax wage rates.     

Consumption and risk sharing over the life cycle

A striking feature of U.S. data on income and consumption is that inequality increases with age. This paper asks if individual-specific earnings risk can provide a coherent explanation. We find that it can. We construct an overlapping generations general equilibrium model in which households face uninsurable earnings shocks over the course of their lifetimes. Earnings inequality is exogenous and is calibrated to match data from the U.S. Panel Study on Income Dynamics. Consumption inequality is endogenous and matches well data from the U.S. Consumer Expenditure Survey. The total risk households face is decomposed into that realized before entering the labor market and that realized throughout the working years. In welfare terms, the latter is found to be more important than the former.     

Credit Card Debt and Default over the Life Cycle

This paper solves an empirically parameterized model of life cycle consumption, which allows for uncollaterized borrowing and the possibility of default. The simulation results show that: (i) "social stigma " and credit limit have a very large impact on default rates; (ii) education level also has a significant effect on the probability of default, namely, through differences in the shape of lifetime labor income profiles; and (iii) the response of simulated default rates to labor income shocks is determined by the nature of labor income uncertainty (temporary versus permanent). Additionally, the model generates simultaneous consumer holdings of credit card debt and liquid assets.     

Financial Frictions,Investment Delay,and Asset Market Interventions

We construct a dynamic macro model to incorporate financial frictions and investment delay. Investment is undertaken by entrepreneurs who face liquidity frictions in the equity market and a collateral constraint in the debt market. After calibrating the model to the U.S. data, we quantitatively examine how aggregate activity is affected by a shock to equity liquidity and a shock to entrepreneurs' borrowing capacity. We then analyze the effectiveness of government interventions in the asset market after such financial shocks. In particular, we compare the effects of government purchases of private equity and of private debt in the open market. In addition, we examine how these effects of government interventions depend on the option to delay investment.     

Inventory Dynamics and Business Cycles: What Has Changed?

To what extent can information-technology led improvements in inventory management account for the apparent moderation of economic fluctuations in the United States since the mid-1980s? We argue that changes in inventory dynamics played a reinforcing—rather than a leading—role in the reduction of output volatility. Since the mid-1980s, inventory dynamics have changed in a manner consistent with a faster resolution of inventory imbalances. However, these changes appear to be a consequence of changes in the response of industry-level sales and aggregate economic activity to monetary policy shocks. Our results suggest that it is the interaction between the changes in inventory behavior at the industry level and the macroeconomic environment—where the latter likely includes changes in the conduct of monetary policy and the responses of the economy to policy disturbances—rather than any single factor, that has contributed importantly to the observed decline in economic volatility.     

Fiscal hedging with nominal assets

We analyze optimal fiscal and monetary policy in an economy with distortionary labor income taxes, nominal rigidities, nominal debt of various maturities and short-selling constraints. Optimal policy prescribes the almost exclusive use of long term debt. Such debt mitigates the distortions associated with hedging fiscal shocks by allowing the government to allocate them efficiently across states and periods.     

Understanding the Distributional Impact of Long‐Run Inflation

The impact of fully anticipated inflation is systematically studied in heterogeneous agent economies with an endogenous labor supply and portfolio choices. In stationary equilibrium, inflation nonlinearly alters the endogenous distributions of income, wealth, and consumption. Small departures from zero inflation have the strongest impact. Three features determine how inflation impacts distributions and welfare: financial structure, shock persistence, and labor supply elasticity. When agents can self‐insure only with money, inflation reduces wealth inequality but may raise consumption inequality. Otherwise, inflation reduces consumption inequality but may raise wealth inequality. Given persistent shocks and an inelastic labor supply, inflation may raise average welfare. The results hold when the model is extended to account for capital formation.     

Inflation and inequality

Cross-country evidence on inflation and income inequality suggests that they are positively related. This article explores the hypothesis that this correlation is the outcome of a distributional conflict underlying the determination of government policies. A political economy model is presented in which equilibrium inflation is positively related to the degree of inequality in income due to the relative vulnerability to inflation of low income households.     

Welfare Consequences of Gradual Disinflation in Emerging Economies

Emerging economies display considerable inequality in monetary asset holdings, rendering the recent disinflation nontrivial. Using a small open‐economy model with uninsurable idiosyncratic risk, this paper shows that a gradual decline of 12% in the quarterly inflation rate leads to an aggregate welfare gain of 0.40% in consumption equivalent terms. The poor gain less than the economy on aggregate, despite holding a more inflation‐prone financial portfolio. This is because unequal cash holdings make inflation tax payments of the poor much smaller than those of the rich. When inflation tax revenues finance redistributive transfers that provide insurance, cross‐sectional gains become even more dispersed.     

Housing and debt over the life cycle and over the business cycle

Housing and mortgage debt are studied in a quantitative general equilibrium model. The model matches wealth distribution, age profiles of homeownership and debt, and frequency of housing adjustment. Over the cycle, the model matches the cyclicality and volatility of housing investment, and the procyclicality of debt. Higher individual income risk and lower downpayments can explain the reduced volatility of housing investment, the reduced procyclicality of debt, and part of the reduced volatility of GDP. In an experiment that mimics the Great Recession, countercyclical financial conditions can account for large drops in housing activity and debt following large negative shocks.     

One Size Fits All? Monetary Policy and Asymmetric Household Debt Cycles in U.S. States

I investigate the nonlinear effects of monetary policy through differences in household debt across U.S. states. After constructing a novel indicator of inflation for the states, I compute state‐specific monetary policy stances as deviations from an aggregate Taylor rule. I find that the effectiveness of monetary policy is curtailed during periods of large household debt imbalances. Moreover, a common U.S. monetary policy does not fit all; it may have asymmetric effects on the economic performance across states, particularly at times of high dispersion in the household debt imbalances, as it may have been the case around the Great Recession.     

Macroeconomic Implications of “Deep Habits” in Banking

Recent empirical evidence shows that price‐cost margins in the market for bank credit are countercyclical in the U.S. economy and that this cyclical behavior can be explained in part from the fact that switching banks is costly for customers (i.e., from a borrower hold‐up effect). Our goal, in this paper, is to study the “financial accelerator” role of these countercyclical margins as a propagation mechanism of macroeconomic shocks. To do so, we apply the “deep habits” framework in Ravn, Schmitt‐Grohé, and Uribe (2006) to financial markets to model this hold‐up effect within a monopolistically competitive banking industry. We are able to reproduce the pattern of price‐cost margins observed in the data, and to show that the real effects of aggregate total factor productivity shocks are larger the stronger the friction implied by borrower hold‐up. Also, output, investment, and employment all become more volatile than in a standard model with constant margins in credit markets. An empirical contribution of our work is to provide structural estimates of the deep habits parameters for financial markets.
