Flattening of Bond Yield Curves for Long Maturities

The paper presents a theoretical proof that flattening of yield curves for par bonds is inevitable for long maturities. This proof implies that behavioral explanations of flattening are unnecessary. The proof also implies that the use of yields to maturity of couponbearing bonds to estimate the true term structure (as well as forward rates) for long maturities has potentially infinite bias, suggesting that a greater effort should be made to directly estimate the true term structure in empirical work.     

The Impact of Collateralization on Swap Rates

Interest rate swap pricing theory traditionally views swaps as a portfolio of forward contracts with net swap payments discounted at LIBOR rates. In practice, the use of marking‐to‐market and collateralization questions this view as they introduce intermediate cash flows and alter credit characteristics. We provide a swap valuation theory under marking‐to‐market and costly collateral and examine the theory's empirical implications. We find evidence consistent with costly collateral using two different approaches; the first uses single‐factor models and Eurodollar futures prices, and the second uses a formal term structure model and Treasury/swap data.     

Debt/Equity Ratio and Expected Common Stock Returns: Empirical Evidence

The expected common stock returns are positively related to the ratio of debt (noncommon equity liabilities) to equity, controlling for the beta and firm size and including as well as excluding January, though the relation is much larger in January. This relationship is not sensitive to variations in the market proxy, estimation technique, etc. The evidence suggests that the “premium” associated with the debt/equity ratio is not likely to be just some kind of “risk premium”.     

INFORMALIZATION OF INDUSTRIAL LABOR IN INDIA: EFFECTS OF LABOR MARKET RIGIDITIES AND IMPORT COMPETITION

Since the 1980s, industrial labor in India has been increasingly informalized, manifested in a rising share of unorganized sector employment and the growing use of temporary and contract workers, and subcontracting in organized manufacturing. Using unit‐level data from the National Sample Survey employment–unemployment survey for 2004–5, the paper investigates econometrically whether labor market rigidities and import competition have been responsible for the informalization of industrial labor in India. The results of econometric models show that labor market reforms tend to increase the creation of regular jobs, while import competition tends to raise casual employment among workers with education levels above primary.     

TRADE LIBERALIZATION AND PRICE‐COST MARGIN IN INDIAN INDUSTRIES

Using panel data for 137 three‐digit industries for 1980/81 to 1997/98, the paper examines the effect of trade liberalization on price‐cost margins in Indian industries. An econometric model is estimated to explain variations in price‐cost margins, taking tariff and nontariff barriers among the explanatory variables. The results indicate that the lowering of tariffs and removal of quantitative restrictions on imports of manufactures in the 1990s had a significant pro‐competitive effect on Indian industries, particularly concentrated industries, tending to reduce the price‐cost margins. The paper notes that despite the pro‐competitive effects of trade liberalization reinforced by domestic industrial deregulation, the price‐cost margin increased in the post‐reform period in most industries and aggregate manufacturing, which is attributed to a marked fall in the growth rate of real wages and a significant reduction in labor's income share in value added in the post‐reform period, reflecting perhaps a weakening of industrial labor's bargaining power.     

Strategyproof Cost Sharing of Multiple Excludable Public Goods

In a model of cost sharing of multiple excludable public goods, we examine the properties of mechanisms satisfying strategyproofness, no subsidy, outcome non‐bossiness, budget balance, individual rationality and consumer sovereignty. We show that such mechanisms in general will not satisfy the equity property of equal treatment of equals. This contrasts with the single excludable public good case.     

An Explanation of Negative Swap Spreads: Demand for Duration from Underfunded Pension Plans

The 30‐year U.S. swap spreads have been negative since September 2008. We offer a novel explanation for this persistent anomaly. Through an illustrative model, we show that underfunded pension plans optimally use swaps for duration hedging. Combined with dealer banks' balance sheet constraints, this demand can drive swap spreads to become negative. Empirically, we construct a measure of the aggregate funding status of defined benefit pension plans and show that this measure helps explain 30‐year swap spreads. We find a similar link between pension funds' underfunding and swap spreads for two other regions.     

Voluntary Disclosure of Intellectual Capital by Hong Kong Companies: Examining Size, Industry and Growth Effects Over Time

This paper investigates voluntary intellectual capital disclosure (ICD) by listed Hong Kong companies. It uses data taken from the years 1992, 1998 and 2002 to give a longitudinal account of voluntary ICD. Company size and industry effects on voluntary ICD are tested, as are the effects of time and level of disclosure on the financial success of a company. We find that levels of voluntary ICD are low but increase over time. Size and industry effects are found, while company financial success is positively correlated with the voluntary disclosure. These findings have implications for policy formulation and practice in relation to the reporting of intellectual capital.
