Cette thèse comporte trois essais en économie des ressources naturelles. Le Chapitre 2 analyse les effets du stockage d’une ressource naturelle sur le bien-être et sur le stock de celle-ci, dans le contexte de la rizipisciculture. La rizipisciculture consiste à élever des poissons dans une rizière en même temps que la culture du riz. Je développe un modèle d’équilibre général, qui contient trois composantes principales : une ressource renouvelable à accès libre, deux secteurs de production et le stockage du bien produit à partir de la ressource. Les consommateurs stockent la ressource lorsqu’ils spéculent que le prix de cette ressource sera plus élevé dans le futur. Le stockage a un effet ambigu sur le bien-être, négatif sur le stock de ressource au moment où le stockage a lieu et positive sur le stock de ressource dans le futur. Le Chapitre 3 étudie les effects de la migration de travailleurs qualifiés dans un modèle de commerce international lorsqu’il y a présence de pollution. Je développe un modèle de commerce à deux secteurs dans lequel j’introduis les questions de pollution et de migration dans l’objectif de montrer que le commerce interrégional peut affecter le niveau de pollution dans un pays composé de régions qui ont des structures industrielles différentes. La mobilité des travailleurs amplifie les effets du commerce sur le capital environnemental. Le capital environnemental de la région qui a la technologie la moins (plus) polluante est positivement (négativement) affecté par le commerce. De plus, je montre que le commerce interrégional est toujours bénéfique pour la région avec la technologie la moins polluante, ce qui n’est pas toujours le cas pour la région qui a la technologie la plus polluante. Finalement, le Chapitre 4 est coécrit avec Yves Richelle. Dans ce chapitre, nous étudions l’allocation efficace de l’eau d’un lac entre différents utilisateurs. Nous considérons dans le modèle deux types d’irréversibilités : l’irréversibilité d’un investissement qui crée un dommage à l’écosystème et l’irréversibilité dans l’allocation des droits d’usage de l’eau qui provient de la loi sur l’eau (irréversibilité légale). Nous déterminons d’abord la valeur de l’eau pour chacun des utilisateurs. Par la suite, nous caractérisons l’allocation optimale de l’eau entre les utilisateurs. Nous montrons que l’irréversibilité légale entraîne qu’il est parfois optimal de réduire la quantité d’eau allouée à la firme, même s’il n’y a pas de rivalité d’usage. De plus, nous montrons qu’il n’est pas toujours optimal de prévenir le dommage créé par un investissement. Dans l’ensemble, nous prouvons que les irréversibilités entraînent que l’égalité de la valeur entre les utilisateurs ne tient plus à l’allocation optimale. Nous montrons que lorsqu’il n’y a pas de rivalité d’usage, l’eau non utilisée ne doit pas être considérée comme une ressource sans limite qui doit être utilisée de n’importe quelle façon.

The main purpose of the present study is to examine the growth and development problems of a new industry ,the chemical industry in the state of kerala. Problems of productivity and efficiency are studied with respect to the different branches of the industry such as fertilizers and insecticides basic inorganic and organic chemicals drugs and pharmaceuticals and miscellaneous chemicals. A study of partial input output linkages between the different chemical units is also attempted. The chemical industry is generally characterized by high linkage effects .These linkages could be used to generate subsidiary industries and thereby help in the growth and diversification of the industry. The efficiency of the working of individual units is also studied to understand the problems involved and to suggest remedial measures.

Thc tea industry in lndia is going through a period of crisis. The crisis in brought about mainly by cost caculation and declining or stagnant prices. The impact of the present crisis is felt most by the owners of tea plantations in Kcrala . The present study assumes significance due to the fact that the critic which already affected Keralas tea industry is now threatening to extend to other tea-growing areas in south India. Today, ensuring a favourablc price to the producers via-a-via possibilities or reducing the cost of production through increase in productivity of land and labour are the main considerations. The main purpose of the study is to analyse the factors behind the crisis as well as exploring immediate and long-term measures for the sustained growth of the industry.

Though of recent origin, commercial poultry farming has achieved momentum in Kerala because of its wide and varied potentials capability of employment creation, low investment, quick returns, lesser combination of various factors of production, enhanced productivity per unit of agricultural land, maintenance of soil fertility etc. Despite all the ancillary attributes characteristic of a thriving venture, the performance of poultry farming in Kerala was not comforting, especially in the case of small and medium size farms. This study has aimed at detailing the various components of cost and revenue in the business of poultry farming, and the adducing of empirical evidences on the nature of relationship of different variables as the gross income, current rate of productivity, extent of capacity utilisation and size of farms in terms of number of birds reared and the farms’ overall financial performance. Alongwith this a descriptive approach was made to highlight the challenges and opportunity poultry farming in Kerala, with special emphasis on its economic and financial aspects.

The importance of industrialisation in achiering rapid economic growth has been recognised in India's development strategy ever since the inception of economic planning in the country. Being the secondary sector in the generation of national income. industry contributes significantly to the process of economic development. Extensive debates have taken place on the nature of the industrialisation strategy to be pursued in the economy since Independence. This is reflected in the industrial policy which evolved through the various five year plans and policy resolutions. Stupendous efforts have been made by the government since the commencement of planning and particularly since the 1960s to industrialise the Indian economy and develop the infrastructural base for sustained industrial development. It is difficult to assess the performance of the industrial sector over the past three decades with respect to the broad objectives of industrialisation. However. there are certain areas in which the achievements have been clearly significant.

Die Dissertation beschäftigt sich mit der komparativen Analyse der deutschen und französischen Innovationssysteme. Ausgehend von der evolutorisch-orientierten Innovationsforschung und der Institutionenökonomik werden die Akteure und deren Interaktionen in den jeweiligen institutionellen Rahmenbedingungen in beiden Innovationssystemen untersucht. Die Arbeit beleuchtet dieses Thema aus verschiedenen Perspektiven und zeichnet sich durch ein breites Methodenspektrum aus. Die Grenzen und Defizite des linearen Innovationsmodells werden aufgezeigt und für ein systemisches, interaktives Verständnis der Entstehung von Innovationen plädiert. Dieses interaktive Modell wird auf die Ebene des nationalen Innovationssystems transponiert, und damit wird der konzeptionelle Rahmen für die weitere Analyse geschaffen. Für die Gestaltung der Innovationssysteme wird die Bedeutung der institutionellen Konfigurationen betont, die von den Innovationsakteuren gewählt werden. Hierfür werden jeweils die Fallbeispiele Frankreich und Deutschland ausführlich untersucht und nach der gleichen Systematik empirisch betrachtet und schließlich werden beide Innovationssysteme systematisch verglichen. Dabei wird auch auf die Pfadabhängigkeiten in beiden Innovationssystemen eingegangen, sowie auf die Notwendigkeit der Berücksichtigung kultureller und historischer Eigenarten der verglichenen Länder. Expertengespräche mit deutschen und französischen Experten, ergänzen die zuvor erzielten Ergebnisse der Arbeit: Durch eine interdisziplinäre Herangehensweise werden politikwissenschaftliche und ökonomische Ansätze miteinander verknüpft, sowie kulturelle Eigenarten berücksichtigt, die Innovationssysteme beeinflussen können. In seinen Schlussfolgerungen kommt der Verfasser zu dem Ergebnis, dass „lernende Politik“ über institutionellen Wandel und Wissenstransfer ein wichtiger Faktor bei der Gestaltung hybrider Institutionen und der staatlichen Innovationspolitik von der „Missions- zur Diffusionsorientierung“ hin ist. Die Betrachtung zweier nationaler Systeme sowie deren Einbindung in internationale Kontexte führt zum Ergebnis, dass die Steuerung der Schnittstelle „Forschung-Industrie“, insbesondere die Rolle der Universitäten und Forschungseinrichtungen in heterogenen Kooperationspartnerschaften, über neue forschungs-und technologiepolitische Instrumente über transnationales Lernen von Institutionen geschehen kann. Dieser institutionelle Wandel wird als Lernprozess betrachtet, der im Übergang zur wissensbasierten Wirtschaft als “comparative institutional advantage“ ein wichtiger Faktor bei der Gestaltung der Institutionen und der staatlichen Technologiepolitik ist.
