This has two implications. First, parents use the same income-dependent relative preferences to measure their children’s well-being. Second, since parents obtain their own utility from consumption in adulthood, they care about their children’s consumption in their adulthood. To capture this latter aspect, I assume that parents are concerned with children’s growth that signals the children’s consumption in adulthood and measure children’s growth with educational output.
This is rooted in the findings in Kageyama
(2012) , which empirically showed that the relationships between LEGAP and these happiness indicators are bidirectional. In one direction, LEGAP negatively affects both HPN and HPGAP . An increase in LEGAP raises women ’ s widowhood ratio, and, since widows are, on average, less happy, it lowers women ’ s average happiness, HPN, and HPGAP . We call this effect the “ marital-status composition effect ” as the marital-status composition plays a central role.
September 1, 2016 Abstract
This article examines the effect of government capital injections into financially trou- bled banks on corporate investment during the Japanese banking crisis of the late 1990s. By helping banks meet the capital requirements imposed by Japanese banking regula- tion, recapitalization enables banks to respond to loan demands, which could help firms increase their investment. To test this mechanism empirically, we combine the balance sheet data of Japanese manufacturing firms with bank balance sheet data and estimate a linear investment model where the investment rate is a function of not only firm pro- ductivity and size but also bank regulatory capital ratios. We find that the coefficient of the interaction between a firm’s total factor productivity measure and a bank’s capital ratio is positive and significant, implying that the bank’s capital ratio affects more pro- ductive firms. Counterfactual policy experiments suggest that capital injections made in March 1998 and 1999 had a negligible impact on the average investment rate, although there was a reallocation effect, shifting investments from low- to high-productivity firms.
• We have assumed that there is only one hedge fund style. What might change if we consider multiple hedge fund styles in the model industry? If the manager’s talent also involves an aptitude for one style over another, then this would be equivalent to having several styles calibrated independently. Since the policy results hinge on broad features of the model and the data, the outcomes of policy experiments are unlikely to change much. The only difference is that some styles tend to rely more heavily on leverage than others, so those are more likely to be hurt by leverage limits. In the working version of the paper, we show that most styles have reported leverage around 1. Out of the fourteen styles considered, four report leverage of around 2 (Convertible Arbitrage, Fixed Income, Equity Market Neutral and Relative Value), and three styles report leverage higher than 2 (Fixed income arbitrage, CTAs and CPOs). Table 8 shows the impact of a leverage cap of 1 on the industry

Note that this assumption implies that learning other bidders’ signals does not affect one’s own valuation – i.e. we have a setting with private, not interdependent values. This assumption may be more palatable for certain securities (such as shorter term securities, which are essentially cash substitutes) than others, but is the most tractable one under which we can pursue the “demand heterogeneity” vs. “market power” decomposition. Note that under this assumption, the additional information that a primary dealer j possesses due to observing her customers’ orders, Z P

load, and if it is a rear or deferred load. Loads are a pricing element (which we have already amortized into the price mea- sure), but they also indicate funds sold with bundled broker services that investors may value. Rear or deferred loads indicate the presence of formal switching costs to removing assets from the fund. We also include a dummy if the fund is an exchange- traded fund (i.e., SPDRs or Barclay’s iShares) to control for the special liquidity and intraday pricing features of ETFs. We mea- sure the number of additional share classes attached to the fund’s portfolio; for a single-share-class fund this value is zero. The number of other funds managed by the same management com- pany is included to capture any value from being associated with a large fund family. Fund age is in the regressions as well. (Here, both the number of family funds and age enter in logs to parsimoniously embody diminishing marginal effects. Recall that we instrument for age because of its possible correlation with unobservable quality.) We add the current fund manag- er’s tenure, measured in years, as a covariate. And while all of the funds in our sample seek to match the return profile of the S&P 500 index, they do exhibit some small differences in their financial characteristics. These can result from skilled trading activities by a fund’s management despite having a severely constrained portfolio. We thus include measures of tax expo- sure (the taxable distributions yield rate), the yearly average of the ratio of monthly fund returns to those of the S&P 500 index, and the standard deviation of monthly returns. To the extent that fund buyers prefer any persistent positive varia- tions in financial performance, these controls should capture much of this effect. 32
Acquirers is the percentage of close CRE potential acquirers whose Tier 1 capital ratios is above the median Tier 1 capital ratio across local potential acquirers. P50 Tier 1 Capital Ratio of HHI Potential Acquirers is the median Tier 1 capital ratio of all potential acquirers whose acquisition of the failed bank would increase local deposit market concentration. % Well-Capitalized HHI Potential Acquirers is the percentage of potential acquirers whose Tier 1 capital ratio is above the median Tier 1 capital ratio among the group of potential acquirers whose acquisition of the failed bank would increase local deposit market concentration. Potential acquirer controls include Size, Liquidity Ratio, % Residential Loans, % CRE Loans, % C&I Loans, % Consumer Loans, 30-89PD Ratio, NPL Ratio, OREO Ratio, and Unused Commitment Ratio .
