The objective of this dissertation is to verify and explain the forward exchange rate unbiasedness hypothesis in the foreign exchange market. Since in most of the cases the unbiasedness hypothesis fails to hold, we try to provide three different explanations of this puzzling behavior in the three essays. The first essay tries to resolve the forward premium puzzle by addressing the model misspecification issue and thereby adding a time-varying risk premium term in the percentage change specification. The risk premium term is modeled using the GARCH-M representation and the model is estimated by applying a GARCH (1, 1) specification. The second essay attributes the failure of the unbiasedness hypothesis to hold to the nonstationarity of the spot and forward exchange rate. It verifies the existence of a cointegrating relationship between the spot and the forward exchange rates and thus specifies an Error Correction Model to better capture the relation between the spot and the forward rates. Further, a cointegrating or the existence of a long run relationship between the spot and forward exchange rates and the domestic and foreign interest rates is tested. It can be viewed as a robustness check where we ensure whether the cointegrated exchange rates are still related in the long run with the inclusion of the interest rates. The objective of the third essay is to apply the generalized method of moments (GMM) to test the unbiasedness hypothesis in the foreign exchange market. Empirical evidence suggests that the spot and forward rates are nonstationary with unit roots and are cointegrated. Cointegration further suggests that the changes in the spot rate can be modeled by an Error Correction Model. The third essay explicitly derives an ECM from the levels specification and uses the GMM estimation technique to test the unbiasedness hypothesis.

The following thesis is a memoir in essays. The narrative is a reflection of memory as a chaotic system. Each essay stands alone as a single memory but also is part of the larger story of the writer's life. The fragmentation of the story lends itself to what Roland Barthes called a readerly text. That is, a reader may enter the text at any point and read the chapters in an order, and by doing this, the reader creates his/her own version of the author's life. The overall narrative arch is one of self-discovery and self-destruction.

M. Tech. Language Practice / Using the narrative essays of undergraduate students, this study aims to understand certain linguistic relations for text construction; namely, the discourse constructs of cohesion, coherence, content, grammar, and text length in English writing. A greater emphasis in this study is given to the understanding of cohesion and coherence as discourse markers. With this in mind, their relation to other salient components of language, such as content, grammar, and text length, are also investigated. This study tries to investigate the features of cohesion and coherence in relation to content, grammar and text length of the English narratives of a personal experience written by sixty-four first and second year students of two South African Universities in the Gauteng province.
