Defined Contribution Plans and the Distribution of Pension Wealth

Over the past 20 years, the defined benefit (DB) plan has been replaced by the defined contribution (DC) plan as the most popular form of pension plan. This study examines the likely consequences of this transformation for both the level and distribution of future pension wealth using a sample of DB and DC plans from the Survey of Consumer Finances. The results reveal that the shift from DB to DC plans is likely to simultaneously increase the level and inequality of pension wealth at retirement. The evidence also suggests that the shift to DC plans may result in less pension wealth at retirement for low‐income workers, women, and minorities.     

A Note: Natural Generalization of Black-Scholes in the Presence of Skewness,Using Stable Processes

The Lognormal price model is generalized to the class of Log-Stable Processes, a family which possesses self-similarity properties usually only associated with the Lognormal, but which, more generally, can model negatively skewed distributions of return. This generalization appears to explain several discrepancies between the Black-Scholes Model and observed market phenomena, such as the variation of implied volatility of option price with exercise price and term to expiry, and the nonzero probability of bankruptcy or ‘crash’. It will be argued that the class of maximally negatively skewed Stable distributions (a class which, paradoxically, contains the normal) may be utilized to produce models which imply these phenomena naturally.     

Why Does the Law Matter? Investor Protection and Its Effects on Investment,Finance, and Growth

Investor protection is associated with greater investment sensitivity to q and lower investment sensitivity to cash flow. Finance plays a role in causing these effects; in countries with strong investor protection, external finance increases more strongly with q, and declines more strongly with cash flow. We further find that q and cash flow sensitivities are associated with ex post investment efficiency; investment predicts growth and profits more strongly in countries with greater q sensitivities and lower cash flow sensitivities. The paper's findings are broadly consistent with investor protection promoting accurate share prices, reducing financial constraints, and encouraging efficient investment.     

Growth Opportunities and the Choice of Leverage, Debt Maturity, and Covenants

We investigate the effect of growth opportunities in a firm's investment opportunity set on its joint choice of leverage, debt maturity, and covenants. Using a database that contains detailed debt covenant information, we provide large‐sample evidence of the incidence of covenants in public debt and construct firm‐level indices of bondholder covenant protection. We find that covenant protection is increasing in growth opportunities, debt maturity, and leverage. We also document that the negative relation between leverage and growth opportunities is significantly attenuated by covenant protection, suggesting that covenants can mitigate the agency costs of debt for high growth firms.     

THE ROLE OF COST IN DETERMINING WHEN FIRMS OFFER BUNDLES*

We model competitive bundling and tying, allowing for marginal cost savings from bundling, fixed costs of product offerings, and variation in customer preferences. Pure bundling can arise either because few people demand only one component or because, with high fixed costs, a single product efficiently satisfies customers with diverse tastes. We conclude by analyzing empirically the bundling of pain relievers with decongestants. The discount for the bundled product is large. We argue that our model provides a simpler, more compelling explanation for the size of the discount than the demand‐centered approach to bundling by a monopolist.     

A New Data Set on Monetary Policy: The Economic Forecasts of Individual Members of the FOMC

This paper describes a new data set of the forecasts of output growth, inflation, and unemployment prepared by individual members of the Federal Open Market Committee. The paper discusses the scope of the data set, possibilities for extending it, and some potential uses. It offers a preliminary examination of some of the cross‐sectional features of the data.     

Immigration of Nurses

This paper examines the effects of immigration on a specific occupation, registered nurses (RNs). To learn whether immigrant nurses reduced the earnings of RNs, we applied techniques developed by Goldin (1994) and Borjas, Freeman, and Katz (1996), but found the effect of immigrant penetration either positive or insignificant. We also found that the supply of immigrant RNs was far more elastic than the supply coming from natives. It is often argued that it will be hard to detect negative effects on wages and employment of natives in local markets, because natives will avoid a market which many immigrants have entered. This study finds no support for this hypothesis in this market, based on data that measures the rate of entry of RNs exactly. We find no adverse effect of immigration on native workers in this occupation.     

Work is a Four‐Letter Word: The Economics of Work in Historical and Critical Perspective*

The article highlights and explains the neglect of the activity of work in much of the mainstream economics literature. The neglect of work is seen to have denied space for mainstream economists to engage with the full range of possibilities for progress in human well‐being. The article also considers perspectives on work from within heterodox or non‐mainstream economics and argues that these perspectives provide a superior foundation for the theorization of work.
