Asset Pricing and Asset Allocation in the Presence of Durable Consumption Goods

Pages : 76
Book Description
We analyze a model of optimal consumption and portfolio selection in which consumption services are generated by holding a durable good. The durable good is illiquid in that a transaction cost must be paid when the good is sold. It is shown that optimal consumption is not a smooth function of wealth; it is optimal for the consumer to wait until a large change in wealth occurs before adjusting his consumption. As a consequence, the consumption based capital asset pricing model fails to hold. Nevertheless, it is shown that the standard, one factor, market portfolio based capital asset pricing model does hold in this environment. It is shown that the optimal durable level is characterized by three numbers (not random variables), say x, y, and z (where x

We analyze a model of optimal consumption and portfolio selection in which consumption services are generated by holding a durable good. The durable good is illiquid in that a transaction cost must be paid when the good is sold. It is shown that optimal consumption is not a smooth function of wealth; it is optimal for the consumer to wait until a large change in wealth occurs before adjusting his consumption. As a consequence, the consumption based capital asset pricing model fails to hold. Nevertheless, it is shown that the standard, one factor, market portfolio based capital asset pricing model does hold in this environment. It is shown that the optimal durable level is characterized by three numbers (not random variables), say x, y, and z (where x lt; y lt; z). The consumer views the ratio of consumption to wealth (c/W) as his state variable. If this ratio is between x and z, then he does not sell the durable. If c/W is less than x or greater than z, then he sells his durable and buys a new durable of size S so that S/W = y. Thus y is his quot;targetquot; level of c/W. If the stock market moves up enough so that c/W falls below x, then he sells his small durable to buy a larger durable. However, there will be many changes in the value of his wealth for which c/W stays between x and z, and thus consumption does not change. Numerical simulations show that small transactions costs can make consumption changes occur very infrequently. Further, the effect of transactions costs on the demand for risky assets is substantial.

Book Description
In this paper, we investigate the implications of non-separable preferences over durable and nondurable consumption for asset pricing tests when adjusting durable consumption is costly. In an economy without adjustment costs, in which a frictionless rental market exists for the durable good, the standard Euler equation with respect to nondurable consumption will hold for each individual agent as well as for aggregate data. If the adjustment of the durable good is costly, however, aggregation generally fails. We use aggregate data to find substantial deviations from the frictionless model, consistent with the presence of non-convex adjustment costs for the durable good. We also show how empirical asset pricing tests that use aggregate data can be affected by these deviations. We then propose and implement asset pricing tests that are robust to the presence of adjustment costs by relying on microeconomic data. Using household-level observations of nondurable food and durable housing consumption, our estimation results suggest that preferences are indeed non-separable in the two consumption goods and that reasonable structural parameters characterize agents' intertemporal utility optimizations.
Asset Pricing and Portfolio Choice in the Presence of Housing

Book Description
The second essay, "Non-durable Consumption Volatility and Illiquid Assets," finds that factors beyond the volatility of asset payoffs may significantly affect the volatility of the agent's consumption stream. The empirical failure of consumption-based asset pricing models is often attributed to the lack of volatility in aggregate measures of consumption. However, I illustrate in this paper that frictions faced by agents may lead to much higher levels of volatility in individual consumption than we observe in the aggregate data. I develop a life-cycle model of in which the consumer derives utility from non-durable consumption and stock in a risky asset: housing. Non-convex adjustment costs generate lumpy changes in the stock of the risky asset over the life-cycle. The model predicts that non-durable consumption volatility is increasing in both the ability to borrow against the assets held in the consumer's portfolio and in the illiquidity of the portfolio.

Exploring Consumption-Based Asset Pricing Model with Stochastic-Trend Forcing Processes

Book Description
Using Canadian data, the consumption-based asset pricing model is studied, defined in terms of nondurable and durable goods consumption. A two-stage estimation procedure is used, which takes account of the presence of common stochastic trends in the forcing processes. This method yields more reasonable estimates of the preference parameters than the previous studies did, and the asset-pricing equation is not rejected by the data. Moreover, the preference specification adopted in this paper allows a number of useful economic information to be obtained. The additive separability assumption and the Cobb-Douglas functional form of the utility function are ruled complements in the sense of Edgeworth and Pareto.
Durable Consumption and Asset Management with Transaction and Observation Costs

Book Description
Abstract: The empirical evidence on rational inattention lags far behind the theoretical developments: micro evidence on the most immediate consequence of observation costs â?' the infrequent observation of state variables â?' is not available in standard datasets. We contribute to filling the gap with two novel household surveys that record the frequency with which investors observe the value of their financial investments, as well as the frequency with which they trade in financial assets and durable goods. We use these data to test some predictions of existing models and show that to match the patterns in the data we need to modify these models by shifting the focus from non-durable to durable consumption. The model we develop features both observation and transaction costs and implies a mixture of time-dependent and state-dependent rules, where the importance of each rule depends on the ratio of the observation to the transaction cost. Numerical simulations show that the model can produce frequency of portfolio observations and asset trading comparable to that of the median investor (about 4 and 0.4 per year, respectively) with small observation costs (about 1 basis point of financial wealth) and larger transaction costs (about 30 basis points of financial wealth). In spite of its small size the observation cost gives rise to infrequent information gathering (between monthly and quarterly). A quantitative assessment of the relevance of the observation costs shows that the behavior of investors is essentially unchanged compared to the one produced by a model with transaction but no observation cost. We test a novel prediction of the model on the relationship between assets trades and durable-goods trades and find that it is aligned with the data
