Welland Canal/St. Lawrence Seaway Authority fonds, 1826-1880, 1905-1951

The Welland Canal Company was formed in 1824 by William Hamilton Merritt. Construction of the first Welland Canal began in 1829 and was completed in 1834. The canal ran south from Port Dalhousie along Twelve Mile Creek to St. Catharines. An extension was built in 1833 to Gravelly Bay, now Port Colborne. As ships became larger and the wooden locks deteriorated, the need for a new canal became apparent. In 1839, the government purchased the Welland Canal Company’s assets and began making plans for the construction of a second canal. Construction began in 1841 and was completed by 1845. In 1887, a third Welland Canal was completed, which operated until 1932, when a fourth canal was completed. This canal remains in operation today.

Essais sur la gestion des ressources forestières

Cette thèse est composée de trois essais en économie forestière. Les deux premiers s'intéressent à la fixation de la redevance optimale à laquelle fait face le propriétaire d'une ressource forestière dans un contexte d'information asymétrique. Le troisième analyse l'impact à long terme du recyclage sur la surface de terre affectée à la forêt. La gestion des ressources forestières implique souvent la délégation des droits de coupe par le propriétaire forestier à une entreprise exploitante. Cette délégation prend la forme d'un contrat de concession par lequel le propriétaire forestier octroie les droits d'exploitation aux compagnies forestières, en contrepartie d'une redevance (transfert monétaire). L'octroie des droits d'exploitation s'effectue généralement sous plusieurs modes, dont les plus répandus sont les appels d'offres publics et les contrats de gré à gré, où le propriétaire forestier et la firme exploitante spécifient entre autres la redevance dans les clauses d'exploitation de la forêt. Pour déterminer le mécanisme optimal (choix de la firme, âge de coupe et redevance), le propriétaire forestier a idéalement besoin de connaître les coûts de coupe et de reboisement. Or en réalité, les firmes sont mieux informées sur leurs coûts que le propriétaire forestier. Dans ce contexte d'information asymétrique, le mécanisme optimal doit donc prendre en considération des contraintes informationnelles. Les deux premiers essais caractérisent, sous ces conditions, l'âge de coupe optimal (la rotation optimale) et la redevance optimale. Le premier essai examine le contrat optimal quand le propriétaire forestier cède les droits de coupes à une firme par un accord de gré à gré ou par une procédure d'appel d'offre public au second prix. L'analyse du problème est menée premièrement dans un contexte statique, dans le sens que les coûts de coupe sont parfaitement corrélés dans le temps, puis dans un contexte dynamique, où les coûts sont indépendants dans le temps. L'examen en statique et en dynamique montre que la rotation optimale va satisfaire une version modifiée de la règle de Faustmann qui prévaudrait en information symétrique. Cette modification est nécessaire afin d'inciter la firme à révéler ses vrais coûts. Dans le cas statique, il en résulte que la rotation optimale est plus élevée en information asymétrique qu'en situation de pleine information. Nous montrons également comment le seuil maximal de coût de coupe peut être endogénéisé, afin de permettre au propriétaire d'accroître son profit espéré en s'assurant que les forêts non profitables ne seront pas exploitées. Nous comparons ensuite la redevance optimale en information asymétrique et symétrique. Les redevances forestières dans un arrangement de gré à gré étant généralement, en pratique, une fonction linéaire du volume de bois, nous dérivons le contrat optimal en imposant une telle forme de redevance et nous caractérisons la perte en terme de profit espéré qui résulte de l'utilisation de ce type de contrat plutôt que du contrat non linéaire plus général. Finalement, toujours dans le contexte statique, nous montrons à travers un mécanisme optimal d'enchère au second prix qu'en introduisant ainsi la compétition entre les firmes le propriétaire forestier augmente son profit espéré. Les résultats obtenus dans le contexte dynamique diffèrent pour la plupart de ceux obtenus dans le cas statique. Nous montrons que le contrat optimal prévoit alors que chaque type de firme, incluant celle ayant le coût le plus élevé, obtient une rente strictement positive, laquelle augmente dans le temps. Ceci est nécessaire pour obtenir la révélation à moindre coût à la période courante du véritable type de la firme. Comme implication, la rotation optimale s'accroît aussi dans le temps. Finalement, nous montrons qu'il y a distorsion en asymétrique d'information par rapport à l'optimum de pleine information même pour le coût le plus bas (la réalisation la plus favorable). La concurrence introduite dans le premier essai sous forme d'enchère au second prix suppose que chaque firme connaît exactement son propre coût de coupe. Dans le deuxième essai nous relâchons cette hypothèse. En réalité, ni le propriétaire forestier ni les firmes ne connaissent avec précision les coûts de coupe. Chaque firme observe de manière privée un signal sur son coût. Par exemple chaque firme est autorisée à visiter un lot pour avoir une estimation (signal) de son coût de coupe. Cependant cette évaluation est approximative. Ainsi, le coût de chaque firme va dépendre des estimations (signaux) d'autres firmes participantes. Nous sommes en présence d'un mécanisme à valeurs interdépendantes. Dans ce contexte, la valeur d'une allocation dépend des signaux de toutes les firmes. Le mécanisme optimal (attribution des droits d'exploitation, redevance et âge de coupe) est exploré. Nous déterminons les conditions sous lesquelles le mécanisme optimal peut être implémenté par une enchère au second prix et dérivons la rotation optimale et le prix de réserve dans le contexte de ce type d'enchère. Le troisième essai de la thèse analyse l'impact à long terme du recyclage sur la surface de terre affectée à la forêt. L'un des principaux arguments qui milite en faveur du recours au recyclage est que cela entraînerait une réduction de la coupe de bois, épargnant ainsi des arbres. L'objectif est donc d'aboutir à un nombre d'arbres plus important qu'en l'absence de recyclage. L'idée d'accroître le stock d'arbre tient au fait que les forêts génèrent des externalités: elles créent un flux de services récréatifs, freinent l'érosion des sols et des rives des cours d'eau et absorbent du dioxyde de carbone présent dans l'atmosphère. Étant donné la présence d'externalités, l'équilibre des marchés résulterait en un nombre d'arbre insuffisant, justifiant donc la mise en oeuvre de politiques visant à l'accroître. Le but de ce troisième essai est de voir dans quelle mesure la promotion du recyclage est un instrument approprié pour atteindre un tel objectif. En d'autres mots, comment le recyclage affecte-t-il à long terme la surface de terre en forêt et l'âge de coupe? Nous étudions cette question en spécifiant un modèle dynamique d'allocation d'un terrain donné, par un propriétaire forestier privé, entre la forêt et une utilisation alternative du terrain, comme l'agriculture. Une fois les arbres coupés, il décide d'une nouvelle allocation du terrain. Il le fait indéfiniment comme dans le cadre du modèle de Faustmann. Le bois coupé est transformé en produit final qui est en partie recyclé comme substitut du bois original. Ainsi, les outputs passés affectent le prix courant. Nous montrons que, paradoxalement, un accroissement du taux de recyclage réduira à long terme la surface forestière et donc diminuera le nombre d'arbres plantés. Par contre l'âge de coupe optimal va s'accroître. L'effet net sur le volume de bois offert sur le marché est ambigu. Le principal message cependant est qu'à long terme le recyclage va résulter en une surface en forêt plus petite et non plus grande. Donc, si le but est d'accroître la surface en forêt, il pourrait être préférable de faire appel à d'autres types d'instruments de politique que celui d'encourager le recyclage.

UK commercial property lease structures: Landlord and tenant mismatch

UK commercial property lease structures have come under considerable scrutiny during the past decade since the property crash of the early 1990s. In particular, tenants complained that the system was unfair and that it has blocked business change. Government is committed, through its 2001 election manifesto, to promote flexibility and choice in the commercial property lettings market and a new voluntary Commercial Leases Code of Practice was launched in April 2002. This paper investigates whether occupiers are being offered the leases they require or whether there is a mismatch between occupier requirements and actual leases in the market. It draws together the substantial data now available on the actual terms of leases in the UK and surveys of corporate occupiers' attitude to their occupation requirements. Although the data indicated that UK leases have become shorter and more diverse since 1990, this is still not sufficient to meet the current requirements of many corporate occupiers. It is clear that the inability to manage entry and exit strategies is a major concern to occupiers. Lease length is the primary concern of tenants and a number of respondents comment on the mismatch between lease length in the UK and business planning horizons. The right to break and other problems with alienation clauses also pose serious difficulties for occupiers, thus reinforcing the mismatch. Other issues include repairing and insuring clauses and the type of review clause. There are differences in opinion between types of occupier. In particular, international corporate occupiers are significantly more concerned about the length of lease and the incidence of break clauses than national occupiers and private-sector tenants are significantly more concerned about leasing in general than public-sector occupiers. Proposed solutions by tenants are predictable and include shorter leases, more frequent breaks and relaxation of restrictions concerning alienation and other clauses. A significant number specify that they would pay more for shorter leases and other improved terms. Short leases would make many of the other terms more acceptable and this is why they are the main concern of corporate occupiers. Overall, the evidence suggests that there continues to be a gap between occupiers' lease requirements and those currently offered by the market. There are underlying structural factors that act as an inertial force on landlords and inhibit the changes which occupiers appear to want. Nevertheless, the findings raise future research questions concerning whether UK lease structures are a constraining factor on UK competitiveness.

Exit strategies for business tenants

Many businesses in the UK occupy premises on fixed term leases, which usually run for several years. During this time property requirements can change. This research critically examines the three main mechanisms by which tenants can bring their leases to an end; breaks, assignment and subletting. We examine the legal rules governing these devices and undertake an analysis of lease data and surveys. Break clauses are providing a useful exit mechanism for many tenants, but they cannot give the more general flexibility of assignment and subletting. However, change is necessary to ensure that these latter provisions provide real flexibility for tenants.

Small business lease reform - can the UK learn from the Australian experience?

This paper addresses the commercial leases policy issue of how to deal with small business tenants. The UK has adopted a voluntary solution to commercial lease reform by using Codes of Practice which is in contrast to the legislative approach adopted by Australia to attempt to solve its perceived problems with small business retail tenancies. The aim of the research was to examine the perceptions of the effectiveness of the legislation in Australia and discuss any implications for the UK policy debate. The research used a combination of literature and legislation review and a semi structured interview survey to investigate the policy aims and objectives of Australian Federal and State Governments, identify the nature and scope of the Australian legislation and examine perceptions of effectiveness of the legislation in informing small business tenants. The situation is complicated in Australia due to leases being a State rather than Federal responsibility therefore the main fieldwork was carried out in one case study State, Victoria. The paper concludes that some aspects of the Australian system can inform the UK policy debate including mandatory information provision at the commencement of negotiations and the use of lease registrars/commissioners. However, there are a number of issues that the Australian legislation does not appear to have successfully addressed including the difficulties of legislating across partial segments of the commercial property market and the collection of data for enforcement purposes.

Small business legislation in Australia: does it provide a solution to part of the UK lease reform debate?

This paper addresses the commercial leases policy issue of how to deal with small business tenants. The UK has adopted a voluntary solution to commercial lease reform by using Codes of Practice which is in contrast to the legislative approach adopted by Australia to attempt to solve its perceived problems with small business retail tenancies. The major aim of the research was to examine the perceptions of the effectiveness of the legislation in Australia and discuss any implications for the UK policy debate but the results of the research also raise questions for the Australian regime. The research used a combination of literature and legislation review and a semi structured interview survey to investigate the policy aims and objectives of Australian Federal and State Governments, identify the nature and scope of the Australian legislation and examine perceptions of effectiveness of the legislation in informing small business tenants. The situation is complicated in Australia due to leases being a State rather than Federal responsibility therefore the main fieldwork was carried out in one case study State, Victoria. The paper concludes that some aspects of the Australian system can inform the UK policy debate including mandatory information provision at the commencement of negotiations and the use of lease registrars/commissioners. However, there are a number of issues that the Australian legislation does not appear to have successfully addressed including the difficulties of legislating across partial segments of the commercial property market and the collection of data for enforcement purposes.

Information sources and advice used by small business tenants when leasing commercial property

Many small businesses lease commercial premises. The terms of a lease can affect the ability of the business to grow and adapt and have an impact on cashflow. Ensuring that they have the information with which to negotiate terms is part of the UK government policy focus on small businesses. Such information is most effectively disseminated through the sources of advice that small businesses use during the leasing process. Therefore these sources of advice need identifying. An interview survey of small business tenants who have recently taken leases provides initial results that suggest small businesses do not seek out advice during the leasing process or see the need to be better informed. The only formal professional input is from solicitors but this is not until after the main commercial terms have been agreed. The landlords’ letting agents play a key, but ambiguous, role in providing information as well as advice. These results suggest that the most effective way of disseminating information by government could be via the letting agents, the very people with whom the tenants are negotiating.

Do small business tenants need protecting in commercial lease negotiations?

This paper sets out the findings relating to small business tenants of a major UK Government funded study into the commercial and industrial property landlord and tenant relationship. The UK Government is concerned that small business tenants do not appreciate many of the implications of signing leases, which in the UK are generally longer than in most other countries of the world. The objectives of the paper are to identify the characteristics of leases in the UK and any differences between those signed by small, medium and larger companies. It also examines the negotiation process and identifies whether small business tenant negotiations exhibit different characteristics. The findings are that small business tenants occupy on different terms to larger tenants including shorter terms and that the negotiation process is also different. Many small business tenants are unrepresented at the commercial stage of negotiations and take the first terms on offer. They are largely unaware of attempts to make them more informed by voluntary industry Codes of Practice. This can lead to small business tenants being unaware of the implications of certain terms within leases, hence the continuing Government concern over the issue.

Are property agents to blame for upward only rent reviews?

In negotiating commercial leases, many landlords and tenants employ property agents (brokers) to act on their behalf; typically these people are chartered surveyors. The aim of this paper is to explore the role that these brokers play in the shaping of commercial leases in the context of the current debate in the UK on upward only rent reviews. This role can be described using agency theory and the theories of professionalism. These provide expectations of behaviour which show inherent tensions between the role of agent and professional, particularly regarding the use of knowledge, autonomy and the obligation to the public interest. The parties to eleven recent lease transactions were interviewed to see if the brokers conformed to the expectations of agency theory or professionalism. Brokers that acted for industrial and office tenants behaved as professionals in using their expertise to determine lease structures. However, those acting for landlords and retail tenants simply followed instructions and behaved as conduits for their clients, a role more usually associated with that of an agent within the principal-agent relationship. None of the landlords’ brokers saw themselves as having responsibilities beyond their clients and so they were not promoting the discussion of alternatives to the UORR. The evidence from these case studies suggests that agents are not professionals; to behave entirely as an agent is to contradict the essential characteristics of a professional. While brokers cannot be held entirely responsible for the lack of movement on the UORR, by adopting predominantly agent roles then they must take some of the blame. However, behind this may be a much larger issue that needs to be explored; the institutional pressures that lead to professionals behaving in this way.

Relative values: residential leasehold reform in England and Wales - valuation of lease extension and enfranchisement

This research report was commissioned by the DETR and examines valuation issues relating to leasehold enfanchisement and lease extension - the right for flat owners to collectively purchase the freehold or buy a longer lease. The two factors examined examined in detail are the yield to be applied when capitalising the ground rent and the relative value of leases with a relatively short period left to run as against the value of the freehold or a new long lease, which determines the level of 'marriage level'. The research report will be of interest to all those involved in the valuation of residential leasehold property and those with an interest in legislative proposals for leasehold reform.

The role of serviced offices in the corporate real estate supply chain

The paper analyses the evolving corporate real estate supply chain and the interaction of this evolution with emerging business models in the serviced office sector. An enhanced model of the corporate real estate portfolio is first presented incorporating vacant, alienated and transitory space. It is argued that the serviced office sector has evolved in response to an increasingly diverse corporate real estate portfolio. For the peripheral corporate real estate portfolio, the core serviced workspace product provides the ability to rapidly acquire high-quality workspace and associated support services on very flexible bases. Whilst it is arguably a beta product, the core workspace offer is now being augmented by managed office or back-to-back leases which enables clients to complement the advantages of serviced offices with a wider choice of premises. Joint venture business models are aligned with solutions to problems of vacant space.

Arnold v. Britton: a ratio and two sets of obiter dicta

Arnold v Britton marks the final stage of the longstanding dispute as to the correct interpretation of a number of 99-year leases of chalets on a leisure park at Oxwich, in the Gower peninsula, near Swansea. The aspect of the case which has attracted most discussion has, understandably, been its main ratio: the proper way to construe a provision of a lease which arguably has an absurd result. This will be considered in this case-note. The judgment of the Supreme Court – particularly the judgment of Lord Neuberger PSC – does, however contain some observations on the possible reform of the law on service charges which are of interest to those engaged in this field. It also contains some obiter comments on ‘letting schemes’ which are – in the view of the present author – highly unorthodox. These three rather disparate issues which are raised by this case will be considered in turn. As they have little in common with each other, they will be considered as separate sections.

Teoria de Leilões com Aplicação ao Mercado de Petróleo Brasileiro

O processo de reforma que ocorreu na indústria petrolífera a partir da década de 1990, associada à transferência de serviços de utilidade pública para o setor privado, trouxe mudanças importantes para a economia. Neste contexto, a intensificação do uso de leilões, para a privatização das empresas públicas e para a concessão de direitos de exploração de seus serviços assumiu um papel de grande relevância na economia brasileira. A discussão sobre o desenho de leilão adotado para a venda de blocos petrolíferos é fundamental, pois representa o ponto inicial desta nova política. Sendo assim, este trabalho aborda os principais aspectos que fundamentam a escolha de um formato apropriado de leilão, detalhando as peculiaridades da indústria petrolífera e, finalmente, discutindo os resultados obtidos.
