Ossa, Ralph (2007) International trade and economic development. PhD thesis, London School of Economics and Political Science (United Kingdom).


In this thesis, I theoretically investigate three related aspects of international trade and economic development. First, I present a model of social learning about the suitability of local conditions for new business ventures and explore its implications for the microeconomic patterns of economic development. I show that: i) firms tend to 'rush' into business ventures with which other firms have had surprising success thus causing development to be 'lumpy'; ii) sufficient business confidence is crucial for fostering economic growth; iii) development may involve wavelike patterns of growth where successive business ventures are first pursued and then given up; iv) there is, nevertheless, no guarantee that firms pursue the best venture even in the long-run. Second, I offer a new explanation for the empirical finding that trade liberalization increases firm productivity. In particular, I develop a simple general equilibrium model of trade in which trade liberalization leads to outsourcing as firms focus on their core competencies in response to tougher competition. Since firms are better at performing tasks the closer they are to their core competencies, this outsourcing increases firm productivity. Third, I propose a novel theory of GATT/WTO negotiations which solves two important problems of the standard terms-of-trade theory. First, it is consistent with the fact that GATT/WTO regulations do not constrain export taxes. Second, it does not rely on the terms-of-trade argument but instead emphasizes market access considerations. To achieve this, I consider trade policy in a 'new trade' environment. I first argue that tariffs are inefficiently high in the non-cooperative equilibrium because countries attempt to improve their relative market access at the expense of other countries. I then show how GATT/WTO negotiations can help countries overcome this inefficiency by providing new rationales for the GATT/WTO principles of reciprocity and nondiscrimination.

Research Design and Dissertation in International Development

This information is for the 2017/18 session.

Teacher responsible

Dr Ernestina Coast OLD M. 2.24


This course is compulsory on the MSc in African Development, MSc in Development Management, MSc in Development Studies, MSc in Health and International Development and MSc in International Development and Humanitarian Emergencies. This course is not available as an outside option.

Course content

The course introduces students to a selection of research methods used in development research.  The objective is to enable students to conduct independent research, to assess the methods used to generate evidence, and to critically assess the quality and validity of research analysis and findings in development research and policy.  Students will learn about: the challenges of conducting research; about research design, including how to generate a research question, how to select research methods, how to analyse data, and analytic rigour; what constitutes knowledge; the relative strengths and weaknesses of quantitative and qualitative research; some of the practical and ethical dos and don’ts of doing fieldwork; and, preparing for the dissertation.


30 hours of lectures in the MT. 9 hours of workshops in the ST.

The course combines a dissertation with lectures on research design, methods and use. Each student is assigned an Academic Advisor. The development of the dissertation is conducted under the supervision of a member of the International Development staff, through individual advice and feedback meetings in MT, LT and ST. Students are expected to submit a draft dissertation title and abstract (150-250 words) in the first half of Lent Term.  This is followed by a more detailed dissertation proposal on a topic within Development Studies / Management / IDHE / African Development / Health and International Development. The proposal must be approved by the assigned Academic Adviser. The research proposal forms the basis for discussion, debate and feedback in the compulsory ST dissertation workshops, at which students present their research proposals, led by International Development staff. 


Formative coursework

Students will take formative online Moodle tests, which will be made available in MT. All students are expected to pass these tests. They can be attempted multiple times. 


Dissertation (100%, 10000 words) in the ST.

Students are required to submit a research proposal of not more than 2,000 words the week before the start of ST.

Students will submit a dissertation of not more than 10,000 words, not including references, by midday on the date specified by the Department towards the end of August.
