Saving and Portfolio Allocation Before and After Job Loss

We investigate the development of household labor income, financial wealth, and asset holdings over a 9‐year period around job loss, using unique administrative panel data from Norway. Consistent with predictions from theory, the data show additional saving and a shift toward safer assets in the years leading up to unemployment, and depletion of savings after job loss. In the years after job loss, the households' after‐tax labor income is reduced by about USD 12,500. Over the same time period, households deplete USD 3,000 of their financial assets, of which one third is accumulated prior to the job loss. This suggests that at least some households can foresee and prepare for the upcoming unemployment, which indicates that private savings can, to some extent, serve as a substitute for publicly provided unemployment insurance.     

Saving and investing for early retirement: A theoretical analysis

We study optimal consumption and portfolio choice in a framework where investors adjust their labor supply through an irreversible choice of their retirement time. We show that investing for early retirement tends to increase savings and reduce an agent's effective relative risk aversion, thus increasing her stock market exposure. Contrary to common intuition, an investor might find it optimal to increase the proportion of financial wealth held in stocks as she ages and accumulates assets, even when her income and the investment opportunity set are constant. The model predicts a decrease in risk aversion following strong market gains like those observed in the nineties.     

Optimal consumption and asset allocation with unknown income growth

Recent empirical evidence supports the view that the income process has an individual-specific growth rate component [Baker, M., 1997. Growth-rate heterogeneity and the covariance structure of life-cycle earnings. Journal of Labor Economics 15, 338-375; Guvenen, F., 2007b. Learning your earning: Are labor income shocks really very persistent? American Economic Review 97, 687-712; Huggett, M., Ventura, G., Yaron, A., 2007. Sources of life-cycle inequality. Working paper, University of Pennsylvania]. Moreover, the individual-specific growth component may be stochastic. Motivated by these empirical observations, I study an individual's optimal consumption-saving and portfolio choice problem when he does not observe his income growth. As in standard income fluctuation problems, the individual cannot fully insure himself against income shocks. In addition to the standard income-risk-induced precautionary saving demand, the individual also has learning-induced precautionary saving demand, which is greater when belief is more uncertain. With constant unobserved income growth, changes in belief are not predictable. However, with stationary stochastic income growth, belief is no longer a martingale. Mean reversion of belief reduces hedging demand on average and in turn mitigates the impact of estimation risk on consumption-saving and portfolio decisions.     

Revisiting asset pricing under habit formation in an overlapping-generations economy

By incorporating habit formation into an overlapping-generations economy, we show that the middle-aged consumers’ savings decision has a substantial impact on the equity premium. The higher incentive for savings for the middle-aged, resulting from the habit formation preference, causes an even higher demand for bonds and a lower demand for equity, which eventually generates a lower risk-free rate and a higher required return for holding equity than does the framework of non-habit forming models. Calibration results verify that the habit formation setting, together with an OLG framework is capable of yielding lower bond returns and higher equity returns than the standard CRRA utility models, and the borrowing constraint imposed on the young-aged consumers amplifies the positive effect of habit formation on the equity premium. The findings imply that habit formation preferences within the overlapping-generations framework under the borrowing-constrained economy can provide a more improved explanation of the equity premium puzzle.     

Money and liquidity in financial markets

We argue that there is a connection between the interbank market for liquidity and the broader financial markets, which has its basis in demand for liquidity by banks. Tightness in the market for liquidity leads banks to engage in what we term “liquidity pull-back,” which involves selling financial assets either by banks directly or by levered investors. Empirical tests on the stock market are supportive. Tighter interbank markets are associated with relatively more volume in more liquid stocks; selling pressure, especially in more liquid stocks; and transitory negative returns. We control for market-wide uncertainty and in the process also contribute to the literature on portfolio rebalancing. Our general point is that money matters in financial markets.     

A generalized volatility bound for dynamic economies

We develop a generalization of the Hansen-Jagannathan (1991) volatility bound that (i) incorporates the serial correlation properties of return data and (ii) allows us to calculate a spectral version of the bound. This generalization enables us to judge whether models match important aspects of the data in the long run, at business cycle frequencies, seasonal frequencies, etc. Our bound permits evaluation of models without requiring their explicit solution in a way that respects the dynamic implications of the fundamental component of the models, namely, the Euler equation that links asset returns to the intertemporal marginal rate of substitution.     

The Operating Performance of Firms that Switch Their Stock Listings

In this article we examine the operating performance of stocks that switch from NASDAQ to the American Stock Exchange (AMEX) or the New Stock Exchange (NYSE) and from AMEX to the NYSE. Specifically, we investigate whether post‐listing operating performance is consistent with the reported negative long‐term drift of post‐listing stock returns and whether there is evidence of self‐selection of the listing time. We find evidence of negative post‐listing changes in operating return on assets and sales, which, on a match‐adjusted basis, are significant for the relatively small NASDAQ stocks switching to AMEX. We also find evidence that firms self‐select the time of listing changes.     

The smart money is in cash? Financial literacy and liquid savings among U.S. families

Most financial advisors recommend storing three to six months of expenses in liquid assets in case of an emergency. Yet we estimate that more than half of U.S. families do not have at least three months of their non-discretionary expenses in liquid savings. We find that financial literacy is strongly predictive of having three months of liquid savings, controlling for income, income variability, and even parental resources. We also find that financial literacy predicts liquid savings across the income distribution. These results indicate that accumulation of an emergency fund is not simply a function of income. Finally, financial literacy is predictive of liquid savings even among high illiquid wealth households. This suggests that the phenomenon of “wealthy hand-to-mouth” families may reflect financial mistakes rather than portfolio optimization. Our paper highlights the importance of financial knowledge in explaining families’ preparedness to deal with unexpected expenses or disruption in their income.     

Safe Assets as Commodity Money

This paper presents a model in which safe assets are systemic because they are the medium of exchange in risky assets. It connects the literature from banking and finance on safe assets to the monetary literature on alternative monetary systems involving commodity money, interest bearing money, and private money creation. Because safe assets have intrinsic value, changes in their supply lead to changes in market efficiency. Additionally, because safe assets are costly to produce, there is overproduction of safe assets relative to the social optimum. When the model is calibrated to plausible liquidity premiums the resulting inefficiencies are not large.     

Interest rate co-movements, global factors and the long end of the term spread

The decoupling of US short and long interest rates has been a distinctive feature of the 2000s. We employ recent advances in panel econometrics to document this disconnect for industrial countries and link it to a global latent factor in long term rates. We investigate whether international forces, such as global inflation, global output, or the global savings glut may be behind this global latent factor. The savings glut is the most likely contender, suggesting that reserve accumulation and a search for yield from emerging markets has lowered long rates internationally, driving a wedge between domestic short and long rates.     

The term structure of real interest rates: theory and evidence from UK index-linked bonds

This paper studies the behavior of the default-risk-free real term structure and term premia in two general equilibrium endowment economies with complete markets but without money. In the first economy there are no frictions as in Lucas (Econometrica 46 (1978) 1429) and in the second risk-sharing is limited by the risk of default as in Alvarez and Jermann (Econometrica 68 (2000) 775; Rev. Financial Studies 14 (2001) 1117). Both models are solved numerically, calibrated to UK aggregate and household data, and the predictions are compared to data on real interest rates constructed from the UK index-linked data. While both models produce time-varying risk or term premia, only the model with limited risk-sharing can generate enough variation in the term premia to account for the rejections of expectations hypothesis.     

Financial market participation and the apparent instability of money demand

This paper uses multi-period cross-sectional data on financial assets holdings to shed light on the postwar stability of money demand in the United States. I first present a new measure of the evolution of financial market participation, by relating participation to the extensive margins of money demand, and quantify the influence of wealth on participation decisions. I then relate the increase in participation to the period of “missing money” and to the subsequent higher interest rate elasticity of monetary aggregates. The paper indicates that time-series estimations of money demand relationships are inherently flawed and tend to inappropriately suggest instability.     

Determinants of the Savings and Fixed Asset Holdings of Turkish Migrants in Germany

This paper investigates the determinants of the bank savings and fixed assets of Turkish migrants residing in Germany. We find that migrants with firmer roots in Germany are more likely to hold savings and fixed assets in Germany, and those with stronger links to Turkey are more likely to hold savings and fixed assets in Turkey. As expected, income is a positive determinant of savings and fixed assets in both countries. Although age has a positive impact on savings and fixed assets in Turkey, it has a negative impact on savings in Germany. These results shed new light on Turkish migrants' short- and long-term savings in Turkey and Germany.     

Longevity risk, retirement savings, and financial innovation

Over the last couple of decades unprecedented increases in life expectancy have raised important concerns for retirement savings. We solve a life-cycle model with longevity risk, which can be hedged through endogenous saving and retirement decisions. We investigate the benefits of financial assets designed to hedge the shocks to survival probabilities. When longevity risk is calibrated to match forward-looking projections, those benefits are substantial. This lends support to the idea that such hedging should be pursued by defined benefit pension plans on behalf of their beneficiaries. Finally, we draw implications for optimal security design.     

Income Uncertainty and IRAs

In a precautionary savings setting, since Individual Retirement Accounts (IRAs) are poor substitutes for precautionary savings due to early withdrawal penalties, those facing more income uncertainty are expected to prefer more liquid assets. This paper investigates the role of income uncertainty in IRA participation. Confidential tax panel data is used to construct a measure of income uncertainty. Greater income uncertainty is found to have a negative influence on IRA participation for those in the immediate pre-retirement stage of the life-cycle. The results appear to be consistent with buffer-stock models of savings where income uncertainty is predicted to have a large effect on wealth accumulation beginning around age 50.     

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.     

On the Structural Interpretation of the Smets–Wouters “Risk Premium” Shock

This article shows that the “risk premium” shock in Smets and Wouters (2007) can be interpreted as a structural shock to the demand for safe and liquid assets such as short‐term U.S. Treasury securities. Several implications of this interpretation are discussed.     

Why does junior put all his eggs in one basket? A potential rational explanation for holding concentrated portfolios

Empirical studies of household portfolios show that young households, with little financial wealth, hold underdiversified portfolios that are concentrated in a small number of assets, a fact often attributed to behavioral biases. We present a potential rational alternative: we show that investors with little financial wealth, who receive labor income, rationally limit the number of assets they invest in when faced with financial constraints such as margin requirements and restrictions on borrowing. We provide theoretical and numerical support for our results and identify the ratio of financial wealth to labor income as a useful control variable for household portfolio studies.     

The term structure of CD rates and monetary policy transmission

The paper investigates the term structure of CD rates and its relationship with the federal funds rate or monetary policy. The term structure derived in this paper is governed primarily by the federal funds rate and secondarily by banks’ income smoothing behavior. It is consistent with the estimation results and differs significantly from the standard term structure of interest rates. The downturn phase of business cycles appears to be accompanied by more aggressive income smoothing by banks (compared with the upturn phase) due to their pessimistic expectations of future profits. The compositional shift in banks’ liabilities during the downturn phase away from CDs toward transaction deposits may pose a greater withdrawal risk for banks.     

Capital over the Business Cycle: Renting versus Ownership

We find that capital renting makes up one‐fifth of U.S. capital expenditures, and it increases during downturns. Further, we present cross‐country evidence that output losses after financial crises are smaller where renting is more prevalent. To understand these findings, we build a general equilibrium model with borrowing constraints and with the option to rent or buy capital. The countercyclicality of rentals occurs because their supply increases, as renting serves as an additional means of savings when credit markets malfunction. Moreover, demand also shifts toward rentals as they become relatively cheaper. By absorbing excess savings, renting mitigates financial crises.
