Do Bonds Span the Fixed Income Markets? Theory and Evidence for Unspanned Stochastic Volatility

Most term structure models assume bond markets are complete, that is, that all fixed income derivatives can be perfectly replicated using solely bonds. How ever, we find that, in practice, swap rates have limited explanatory power for returns on at–the–money straddles—portfolios mainly exposed to volatility risk. We term this empirical feature "unspanned stochastic volatility" (USV). While USV can be captured within an HJM framework, we demonstrate that bivariate models cannot exhibit USV. We determine necessary and sufficient conditions for trivariate Markov affine systems to exhibit USV. For such USV models, bonds alone may not be sufficient to identify all parameters. Rather, derivatives are needed.     

Real Estate Investment Trusts, Small Stocks and Bid-ask Spreads

This study examines the liquidity of Real Estate Investment Trusts (REITs), as measured by their bid-ask spread. We find that REIT spreads have increased over the period 1986–1990, are inversely related to market capitalization, and are similar in magnitude to spreads on other stocks of comparable size. Analysis of variance tests indicate that REIT spreads are similar across equity, mortgage and hybrid asset types. Multivariate regression results indicate that market capitalization is the primary determinant of REIT bid-ask spreads, and spreads are larger for National Association of Securities Dealers Automated Quotations (NASDAQ) REITs than for New York Stock Exchange (NYSE) REITs. The regression results also indicate that spreads are lower for equity REITs than for mortgage or hybrid REITs, and are inversely related to the fraction of the REIT's shares held by institutional investors. The similarity between REIT spreads and those of other common stocks holds in both bull and bear real estate markets and suggests that, from a liquidity perspective, REITs are similar to other common stocks.     

Despair and the UN development decade

The flow of aid and trade to the third world will be stilled if inflation and recession persist- as seems likely for the 1980s. UN hopes for a Development Decade and a New International Economic Order stand minimal chances of success. Members of OECD, Comecon and OPEC have ignored third world voices at the UN, IMF and elsewhere, for short-sighted, perilous reasons of self-protection.     

Payoff complementarities and financial fragility: Evidence from mutual fund outflows

The paper provides empirical evidence that strategic complementarities among investors generate fragility in financial markets. Analyzing mutual fund data, we find that, consistent with a theoretical model, funds with illiquid assets (where complementarities are stronger) exhibit stronger sensitivity of outflows to bad past performance than funds with liquid assets. We also find that this pattern disappears in funds where the shareholder base is composed mostly of large investors. We present further evidence that these results are not attributable to alternative explanations based on the informativeness of past performance or on clientele effects. We analyze the implications for funds’ performance and policies.     

The role of accounting disaggregation in detecting and mitigating earnings management

Though ample empirical evidence alludes to the importance of disaggregated accounting data in the context of earnings management, extant theory considers biases in reporting mostly at the aggregated level of the accounting report. By introducing accounting disaggregation into the conventional theoretical framework of earnings management, this study highlights the essential role that disaggregated accounting data play in detecting and mitigating reporting manipulations. Disaggregated reports are shown to be especially effective when they consist of accounting items that are tightly interrelated by their fundamental economic nature, differ considerably in their sensitivity to reporting manipulations, and vary in their signs.     

Explaining gender differentials in agricultural production in Nigeria

This article uses data from the General Household Survey Panel 2010–2011 to analyze differences in agricultural productivity across male and female plot managers in Nigeria. The analysis utilizes the Oaxaca‐Blinder decomposition method, which allows for decomposing the unconditional gender gap into: (i) the portion caused by observable differences in the factors of production (endowment effect) and (ii) the unexplained portion caused by differences in returns to the same observed factors of production (structural effect). The analysis is conducted separately for the North and South regions, excluding the west of the country. The findings show that in the North, women produce 28% less than men after controlling for observed factors of production, while there are no significant gender differences in the South. In the decomposition results, the structural effect in the North is larger than the endowment at the mean. Although women in the North have access to less productive resources than men, the results indicate that even if given the same level of inputs, significant differences still emerge. However, for the South, the decomposition results show that the endowment effect is more important than the structural effect. Access to resources explains most of the gender gap in the South and if women are given the same level of inputs as men, the gap will be minimal. The difference in the results for the North and South suggests that policy should vary by region.     

The Political Economy of Strategic Trade Policy and the Brazil–Canada Export Subsidies Saga

In this paper we study the on‐going trade dispute between Canada and Brazil on export subsidies in the aircraft industry and the reasons for its escalation. This is a peculiar case of strategic trade policy insofar as the good, i.e. regional jets, is heavily dependent on sub‐systems that are imported in the two countries. The hypothesis that the dispute solely derives from the search for rents and externalities is therefore incomplete. Without downplaying the role of interest politics, we argue that in both countries ideas about the goals of trade policy have an important place in explaining why this dispute drags on. For Canada, the belief in a rules‐based trading regime has led it to strongly oppose violations, while insecurity about its competitiveness has led to a variety of government schemes to support firms in advanced sectors like aerospace. For Brazil, its place as a leader of the developing world acted as a rallying point for government and firms alike. The research also argues that the WTO process has actually made a resolution of the dispute more difficult by making it too costly for firms and countries to comply with the costs of losing.     

Predator–Prey Model Estimates of the Cyclical Profit Squeeze

This paper extends the empirical literature on the cyclical profit squeeze (CPS) theory of crisis by developing a multivariate model with superior decomposition methods. A structural time series (unobserved components) model with trend and structural VAR components is employed. The VAR captures the dynamic cyclical interaction between unemployment and profit's share of income and is interpreted as a linear version of Goodwin's (1967) predator-prey model. Model extensions incorporate the accumulation process and structural shifts. Estimation results for the US economy are used to sort out the controversial relevance of the CPS in the post-1970 period. It is concluded that the CPS is relevant during the period from 1949 to 1985, but is moderately weakened in the post-1970 period. Inconclusive statistical support for the CPS is found for the post-1985 era.
