This paper investigates the dynamics of individual portfolios in a unique data set containing the disaggregated wealth of all households in Sweden. Between 1999 and 2002, we observe little aggregate rebalancing in the financial portfolio of participants. These patterns conceal strong household-level evidence of active rebalancing, which on average offsets about one-half of idiosyncratic passive variations in the risky asset share. Wealthy, educated investors with better diversified portfolios tend to rebalance more actively. We find some evidence that households rebalance toward a greater risky share as they become richer. We also study the decisions to trade individual assets. Households are more likely to fully sell directly held stocks if those stocks have performed well, and more likely to exit direct stockholding if their stock portfolios have performed well; but these relationships are much weaker for mutual funds, a pattern that is consistent with previous research on the disposition effect among direct stockholders and performance sensitivity among mutual fund investors. When households continue to hold individual assets, however, they rebalance both stocks and mutual funds to offset about one-sixth of the passive variations in individual asset shares. Households rebalance primarily by adjusting purchases of risky assets if their risky portfolios have performed poorly, and by adjusting both fund purchases and full sales of stocks if their risky portfolios have performed well. Finally, the tendency for households to fully sell winning stocks is weaker for wealthy investors with diversified portfolios of individual stocks.

This paper studies the pricing of volatility risk using the first-order conditions of a long-term equity investor who is content to hold the aggregate equity market instead of overweighting value stocks and other equity portfolios that are attractive to short-term investors. We show that a conservative long-term investor will avoid such overweights to hedge against two types of deterioration in investment opportunities: declining expected stock returns and increasing volatility. We present novel evidence that low-frequency movements in equity volatility, tied to the default spread, are priced in the cross section of stock returns.

We investigate the relation between firms' weighted average cost of capital and internal financial resources, using mandatory pension contributions as a proxy for internal financial resources. Rauh (2006) documents a negative association between mandatory pension contributions and capital expenditures. We find that an increase in mandatory pension contributions increases the cost of capital, but only for firms facing greater external financing constraints. Our results suggest that firms' cost of capital is an intervening variable that can explain Rauh's finding that mandatory pension contributions (i.e., internal financing constraints) result in foregone investment. Overall, we provide evidence consistent with recent studies (Rauh 2006; Almeida and Campello 2007) that conclude that financial market frictions affect real economic activity and, in particular, corporate investment.

This study investigates the association between quantitative disclosure and information risk, hypothesizing that a greater proportion of numerical information in earnings conference calls decreases information risk and thus increases firm value. We find that, even after controlling for earnings information, more extensive numerical disclosure correlates positively with earnings announcement returns. This effect concentrates in firms with poorer information environments and during periods of heightened performance uncertainty. Finally, we show that a greater proportion of numerical disclosure reduces implied volatility, bid-ask spread, and implied cost of capital. Our findings highlight numerical disclosure's role in reducing information risk and emphasize its importance in financial disclosures.

In this paper, we solve a dynamic model of households' mortgage decisions incorporating labor income, house price, inflation, and interest rate risk. Using a zero‐profit condition for mortgage lenders, we solve for equilibrium mortgage rates given borrower characteristics and optimal decisions. The model quantifies the effects of adjustable versus fixed mortgage rates, loan‐to‐value ratios, and mortgage affordability measures on mortgage premia and default. Mortgage selection by heterogeneous borrowers helps explain the higher default rates on adjustable‐rate mortgages during the recent U.S. housing downturn, and the variation in mortgage premia with the level of interest rates.

Over the period 1975 to 2005, the U.S. dollar (particularly in relation to the Canadian dollar), the euro, and the Swiss franc (particularly in the second half of the period) moved against world equity markets. Thus, these currencies should be attractive to risk‐minimizing global equity investors despite their low average returns. The risk‐minimizing currency strategy for a global bond investor is close to a full currency hedge, with a modest long position in the U.S. dollar. There is little evidence that risk‐minimizing investors should adjust their currency positions in response to movements in interest differentials.

This paper explores the effect of equity volatility on corporate bond yields. Panel data for the late 1990s show that idiosyncratic firm‐level volatility can explain as much cross‐sectional variation in yields as can credit ratings. This finding, together with the upward trend in idiosyncratic equity volatility documented by Campbell, Lettau, Malkiel, and Xu (2001), helps to explain recent increases in corporate bond yields.

We show that the external habit‐formation model economy of Campbell and Cochrane (1999) can explain why the Capital Asset Pricing Model (CAPM) and its extensions are betterapproximate asset pricing models than is the standard onsumption‐based model. The model economy produces time‐varying expected eturns, tracked by the dividend–price ratio. Portfolio‐based models capture some of this variation in state variables, which a state‐independent function of consumption cannot capture. Therefore, though the consumption‐based model and CAPM are both perfect conditional asset pricing models, the portfolio‐based models are better approximate unconditional asset pricing models.

The benefits of endowment destruction documented by Ljungqvist and Uhlig (2015), and the related possibility that consumption can lower habits, are fragile. Both issues result from a particular way of discretely approximating the underlying continuous-time model or of adapting it to jumps. Other ways of calculating the discrete-time approximation or extending the model to jumps easily overturn the results, while making no difference to the model's description of asset prices and quantities. This analysis gives an example of how to extend models so that the jump gives the same result as a jump limit of continuous-sample-path movements.
