Discrete time models of the term structure of interest rates and interest rate contingent claims

In this study, discrete time one-factor models of the term structure of interest rates and their application to the pricing of interest rate contingent claims are examined theoretically and empirically. The first chapter provides a discussion of the issues involved in the pricing of interest rate contingent claims and a description of the Ho and Lee (1986), Maloney and Byrne (1989), and Black, Derman, and Toy (1990) discrete time models. In the second chapter, a general discrete time model of the term structure from which the Ho and Lee, Maloney and Byrne, and Black, Derman, and Toy models can all be obtained is presented. The general model also provides for the specification of an additional model, the ExtendedMB model. The third chapter illustrates the application of the discrete time models to the pricing of a variety of interest rate contingent claims. In the final chapter, the performance of the Ho and Lee, Black, Derman, and Toy, and ExtendedMB models in the pricing of Eurodollar futures options is investigated empirically. The results indicate that the Black, Derman, and Toy and ExtendedMB models outperform the Ho and Lee model. Little difference in the performance of the Black, Derman, and Toy and ExtendedMB models is detected. ^

Illicit interest groups: The political impact of the Medellin drug trafficking organizations in Colombia

Although drug trafficking organizations (DTOs) exist and have an effect on health, crime, economies, and politics, little research has explored these entities as political organizations. Legal interest groups and movements have been found to influence domestic and international politics because they operate within legal parameters. Illicit groups, such as DTOs, have rarely been accounted for—especially in the literature on interest groups—though they play a measurable role in affecting domestic and international politics in similar ways. Using an interest group model, this dissertation analyzed DTOs as illicit interest groups (IIGs) to explain their political influence. The analysis included a study of group formation, development, and demise that examined IIG motivation, organization, and policy impact. The data for the study drew from primary and secondary sources, which include interviews with former DTO members and government officials, government documents, journalistic accounts, memoirs, and academic research. To illustrate the interest group model, the study examined Medellin-based DTO leaders, popularly known as the "Medellin Cartel." In particular, the study focused on the external factors that gave rise to DTOs in Colombia and how Medellin DTOs reacted to the implementation of counternarcotics efforts. The discussion was framed by the implementation of the 1979 Extradition Treaty negotiated between Colombia and the United States. The treaty was significant because as drug trafficking became the principal bilateral issue in the 1980s; extradition became a major method of combating the illicit drug business. The study's findings suggested that Medellin DTO leaders had a one-issue agenda and used a variety of political strategies to influence public opinion and all three branches of government—the judicial, the legislative, and the executive—in an effort to invalidate the 1979 Extradition Treaty. The changes in the life cycle of the 1979 Extradition Treaty correlated with changes in the political power of Medellin-based DTOs vis-à-vis the Colombian government, and international forces such as the U.S. government's push for tougher counternarcotics efforts.

Foreign aid and the national interest : the cases of the United States and Japan

Developed countries give foreign assistance for many reasons, one of which is the protection of national interests. Foreign aid gives a donor country leverage in international relations and is used as a tool of foreign policy. The United States and Japan are the two largest aid donors in the world. Each of these countries exert influence over specific regions through foreign assistance. Although the national interests of each country are different, both use foreign aid to protect these interests. This thesis discusses the means by which the United States and Japan use foreign aid in foreign policy. It looks specifically at U.S. food aid to Central America and Japanese aid to Asia.
