Nominal versus indexed debt: A quantitative horse race

The main arguments in favor and against nominal and indexed debts are the incentive to default through inflation versus hedging against unforeseen shocks. We model and calibrate these arguments to assess their quantitative importance. We use a dynamic equilibrium model with tax distortion, government outlays uncertainty, and contingent-debt service. Our framework also recognizes that contingent debt can be associated with incentive problems and lack of commitment. Thus, the benefits of unexpected inflation are tempered by higher interest rates. We obtain that costs from inflation more than offset the benefits from reducing tax distortions. We further discuss sustainability of nominal debt in developing (volatile) countries.     

Hedging structured credit products during the credit crisis: A horse race of 10 models

Pricing and hedging structured credit products poses major challenges to financial institutions. This paper puts several valuation approaches through a crucial test: How did these models perform in one of the worst periods of economic history, September 2008, when Lehman Brothers went under? Did they produce reasonable hedging strategies? We study several bottom-up and top-down credit portfolio models and compute the resulting delta hedging strategies using either index contracts or a portfolio of single-name CDS contracts as hedging instruments. We compute the profit-and-loss profiles and assess the performances of these hedging strategies. Among all 10 pricing models that we consider the Student-t copula model performs best. The dynamical generalized-Poisson loss model is the best top-down model, but this model class has in general problems to hedge equity tranches. Our major finding is however that single-name and index CDS contracts are not appropriate instruments to hedge CDO tranches.     

Sell on the news: Differences of opinion,short-sales constraints,and returns around earnings announcements

Miller [1977. Risk, uncertainty, and divergence of opinion. Journal of Finance 32, 1151–1168] hypothesizes that prices of stocks subject to high differences of opinion and short-sales constraints are biased upward. We expect earnings announcements to reduce differences of opinion among investors, and consequently, these announcements should reduce overvaluation. Using five distinct proxies for differences of opinion, we find that high differences of opinion stocks earn significantly lower returns around earnings announcements than low differences of opinion stocks. In addition, the returns on high differences of opinion stocks are more negative within the subsample of stocks that are most difficult for investors to sell short. These results are robust when we control for the size effect and the market-to-book effect and when we examine alternative explanations such as financial leverage, earnings announcement premium, post-earnings announcement drift, return momentum, and potential biases in analysts’ forecasts. Also consistent with Miller's theory, we find that stocks subject to high differences of opinion and more binding short-sales constraints have a price run-up just prior to earnings announcements that is followed by an even larger decline after the announcements.     

Many small antelopes make a dragon

This study focuses on small business in Taiwan. It first discusses the most important features that modern small firms provide, how they are involved in the growing integrated world economy, and the recent rising trends in the number of small and medium sized enterprises (SMEs). This trend, which follows an earlier decrease is further investigated in the context of the Taiwan economy. Finally, three conditions of Taiwan’s successful small firm sector are discussed: appropriate policy, global involvement, and entrepreneurship. Alternative small business futures depend on the conditions that encourage the development of SMEs. In one scenario, where SMEs can find the niche markets quickly, and enhance their expertise in logistics, a rise in SMEs in the global market may be expected. In another scenario, if SMEs fail in forming alliances and networks when confronting with giant firms or large Foreign Direct Investment, there might be a reduction in enterprising behavior. Judging from the former performance of Taiwan’s SMEs, it can be concluded that there is a good chance that SMEs will remain a vibrant and important participant of its economy and the world economy in the future.     

How to make India a knowledge-based society

The National Knowledge Commission set up by the Prime Minister of India, Dr. Manmohan Singh, in 2005 was, perhaps, the first of its kind. One of its three objectives is to make India a knowledge-based society. Among the important areas in the country where problems need to be addressed to achieve the above objective, three—education, knowledge empowerment of Panchayats (the lowest of the three-tier local self-government system in India), and ethical commercialization of the country's creative and cultural tradition—are briefly described in the article. Some steps that need to be taken in each area are stated. For example, in regard to education, we must decommercialize school and higher education, and set up 400,000 high schools in the country where children would receive high-quality free education for 10 years—that is, up to the age of 16. As regards the Panchayats, we need to institute a system so that they are empowered through knowledge in areas of immediate interest to them as well as knowledge that would make them truly informed citizens of the country. In regard to traditional knowledge, it needs to be ensured that the keepers and practitioners of this knowledge are compensated adequately and fairly if such knowledge is commercialized.     

It's time to make management a true profession

In the face of the recent institutional breakdown of trust in business, managers are losing legitimacy. To regain public trust, management needs to become a true profession in much the way medicine and law have, argue Khurana and Nohria of Harvard Business School. True professions have codes, and the meaning and consequences of those codes are taught as part of the formal education required of their members. Through these codes, professional institutions forge an implicit social contract with society: Trust us to control and exercise jurisdiction over an important occupational category, and, in return, we will ensurethat the members of our profession are worthy of your trust--that they will not only be competent to perform the tasks entrusted to them, but that they will also conduct themselves with high standardsand great integrity. The authors believe that enforcing educational standards and a code of ethics is unlikely to choke entrepreneurial creativity. Indeed, if the field of medicine is any indication, a code may even stimulate creativity. The main challenge in writing a code lies in reaching a broad consensus on the aims and social purpose of management. There are two deeply divided schools of thought. One school argues that management's aim should simply be to maximize shareholder wealth; the other argues that management's purpose is to balance the claims of all the firm's stakeholders. Any code will have to steer a middle course in order to accommodate both the value-creating impetus of the shareholder value concept and the accountability inherent in the stakeholder approach.

Divergence of opinion and initial public offerings

This article analyzes several IPO patterns in the framework of divergence of opinion. Considering a new industry with few publicly traded companies, the investors in this IPO market do not initially have complete knowledge about the industry, but may learn from other IPOs in the sector. Our model shows that the equilibrium is consistent with empirical evidence documented for IPO underpricing and hot issue markets. We also characterize the association between share overhang, trading volume, and IPO prices. Furthermore, we discuss the decision of going public, analyst coverage, and IPO lockup expiration in the presence of divergent opinions.
