Estimation of global systematic risk for securities listed in multiple markets

In this era of rapid globalization of financial markets there has been a substantial increase in cross-listings of stocks in foreign and regional capital markets. As many as a third to a half of the stocks in some major exchanges are foreign listed. The multiple listings of stocks has major implications for the concept of systematic risk. This paper demonstrates that the estimator for systematic risk and the methodology itself changes when stocks are listed in multiple markets. The paper suggests general procedures, using maximum information from the multiple markets, to obtain the estimator of beta under a variety of assumptions about the error terms of the market models in the different capital markets. The assumptions pertain both to the volatilities of the abnormal returns in each market, and to the relationship between the markets.     

Sale of monopoly information and behavior of rivaling clients: A theoretical perspective

This paper studies a three-stage Bayesian-Cournot game where rivaling firms sign contracts with an information monopoly to purchase proprietary information. The rivaling firms use the external information to create competitive advantage over one another. Knowing the rivalry among its clients, the information monopoly can exploit them by playing one client against another. The information-selling strategy depends on the clients' in-house information technology, the uncertainty of the economic environment, and the number of potential clients. The existence of an information market makes rivaling producers worse off and consumers better off. It is possible that the service of the information monopoly is a private good but a social bad.     

Bus transportation crews planning by goal programming

In the present paper, an integer goal programming model formulation is presented for the bus transportation crews planning to find an optimal schedule in which each crew is assigned two days off (consecutive or non-consecutive) per week and several goals like upper and lower limits on the total number of crews having consecutive and/or non-consecutive days off on each day, lower limit on the number of crews having consecutive days off on the particular pairs of consecutive days, and minimization of the number of crews having non-consecutive days off, are taken into consideration. The model is demonstrated by a numerical example.     

SUSTAINABLE URBANIZATION: NEEDED POLICY CHANGES FOR INDIA

This paper is concerned with two questions: what is it that is unsustainable about the process of urbanization and growth of cities in developing countries?; and why do countries persist with strategies that are evidently unsustainable? Making use of data from India, which today has the second largest urban population in the world, and taking note of increasing global concern for sustainable urbanization, this paper points out that the developing countries have to move beyond a general acceptance of the concept to see it being put into practice.     

Earnings changes associated with relaxing the reconciliation requirement in non-U.S. firms’ SEC filings

We investigate the changes in earnings information content and earnings attributes for non-U.S. firms listed in U.S. equity markets following the 2007 relaxation of the SEC requirement to reconcile IFRS earnings and stockholders’ equity to U.S. GAAP in annual regulatory filings. We analyze a sample of non-U.S. firms listed on U.S. exchanges from 2005 to 2008 that use IFRS, and compare them to non-U.S. firms that continue to use domestic GAAP or U.S. GAAP. Prior literature finds no changes in informativeness following the regulatory change for IFRS-using firms. However, when we partition the IFRS-using firms into two groups based on their history of providing reconciliation information, we find that firms which previously provided more information about the differences between their reporting GAAP and U.S. GAAP had significant increases in the information content of their earnings. In contrast, there is no change in earnings informativeness for firms that provided less informative reconciliations. We regard the reconciliation informativeness as a proxy for firms’ efforts to provide more informative disclosures, which is driven by their disclosure incentives. We also document that the change in the information content of earnings for more informative reconcilers was contemporaneous with a change in earnings attributes for these firms. Consistent with no change in earnings informativeness for less informative reconcilers, there is little change in their earnings attributes. Our results underscore the importance of incorporating disclosure incentives when examining the consequences of a regulatory change.
