Reinforcement Learning and Savings Behavior

We show that individual investors over‐extrapolate from their personal experience when making savings decisions. Investors who experience particularly rewarding outcomes from 401(k) saving—a high average and/or low variance return—increase their 401(k) savings rate more than investors who have less rewarding experiences. This finding is not driven by aggregate time‐series shocks, income effects, rational learning about investing skill, investor fixed effects, or time‐varying investor‐level heterogeneity that is correlated with portfolio allocations to stock, bond, and cash asset classes. We discuss implications for the equity premium puzzle and interventions aimed at improving household financial outcomes.     

The Effect of Audit Quality on Earnings Management*

This study examines the relation between audit quality and earnings management. Consistent with prior research, we treat audit quality as a dichotomous variable and assume that Big Six auditors are of higher quality than non-Big Six auditors. Earnings management is captured by discretionary accruals that are estimated using a cross-sectional version of the Jones 1991 model. Prior literature suggests that auditors are more likely to object to management's accounting choices that increase earnings (as opposed to decrease earnings) and that auditors are more likely to be sued when they are associated with financial statements that overstate earnings (as compared to understate earnings). Therefore, we hypothesize that clients of non-Big Six auditors report discretionary accruals that increase income relatively more than the discretionary accruals reported by clients of Big Six auditors. This hypothesis is supported by evidence from a sample of 10,379 Big Six and 2,179 non-Big Six firm years. Specifically, clients of non-Big Six auditors report discretionary accruals that are, on average, 1.5-2.1 percent of total assets higher than the discretionary accruals reported by clients of Big Six auditors. Also, consistent with earnings management, we find that the mean and median of the absolute value of discretionary accruals are greater for firms with non-Big Six auditors. This result also indicates that lower audit quality is associated with more “accounting flexibility”.

The Integration of Insurance and Taxes in Corporate Pension Strategy

This paper examines the implications of the joint effects of insurance and taxes for the optimal corporate pension strategy. It is shown that neither the “mini-max” nor the “maxi-min” strategy advocated by previous authors is necessarily best in corporate pension management. In the presence of capital market imperfections, the analysis via a single-period contingent-claims model indicates that optimal corporate pension strategy in both asset-allocation and funding decisions can be a noncorner interior solution.     

International Capital Structure Equilibrium

This paper develops a theory of capital structure in an international setting with corporate and personal taxes. We generalize the Miller analysis to an international equilibrium characterized by differential international taxation and inflation in otherwise perfect international capital markets. Our analysis highlights the key role that corporate tax arbitrage plays in generating an international capital structure equilibrium, and we set forth a number of mechanisms for tax arbitrage transactions. We close the paper by outlining some implications of our analysis for national differences in capital structure, the International Fisher Effect, and international tax effects on yield differentials.     

The Puzzle of Financial Leverage Clienteles

Empirically, it appears that common stock of publicly traded corporations with high-debt ratios tends to be held by investors with relatively low marginal taxes while the stock in companies with little debt is held by investors in high-tax brackets. A number of authors have argued that in an equilibrium similar to the one described by Miller [8], these clienteles should exist. We argue that standard portfolio theory does not imply financial leverage clienteles for publicly traded firms. We explain the empirical relationship between investor tax rates and leverage ratios by the existence of dividend clienteles and a positive relationship between dividend yield and leverage ratios.     

解读后现代服装

后现代社会中,服装样式如此之多,时尚变化如此之快,都是前所未有的.人们被众多的时装发布会、媒体报道所包围,令人眼花缭乱是人们对服装的评价,似乎美学规则一夜之间被打破,设计师可以将看起来是垃圾的东西挂在模特身上走上T形台,消费者可以去二手市场淘出半世纪以前的服装穿在身上,招摇过市.时装对于人们来说似乎越来越难懂了,主要原因在于新艺术在对传统颠覆的同时并没有建立起相应的审美理论体系.

Is the Phillips Curve A Curve? Some Evidence and Implications for Australia

The Phillips curve has generally been estimated in a linear framework. This paper investigates the possibility that the Phillips curve is indeed a curve, and shows that a convex short-run Phillips curve may be a more accurate representation of reality than the traditionally used linear specification. The paper also discusses the policy implications of convexity in the Phillips curve. These include the need for policy to be forward looking and to act pre-emptively. Convexity provides a strong rationale for stabilization policy, and it reinforces the need for policy makers to proceed cautiously. It also implies that deep recessions may have only a marginally greater disinflationary impact than shallower ones, unless they induce large credibility bonuses.
