Ancrage de l'idéologie de l'Union des producteurs agricoles et de l'utopie de l'Union paysanne dans des significations imaginaires sociales.

Le but de cette thèse est de découvrir l'idéologie de l'Union des producteurs agricoles et l'utopie de l'Union paysanne et de les interpréter à la lumière de "significations imaginaires sociales" déterminantes de notre période historique. Dans la première partie de notre thèse, nous présentons l'évolution de l'imaginaire social du syndicalisme agricole québécois de 1924 à 2005. Nous distinguons quatre périodes et notre étude s'attarde à la dernière, c'est-à-dire celle qui débute en 2001 avec la naissance de l'Union paysanne. Afin d'étudier cette période nous présentons d'abord l'imaginaire social de la société, c'est-à-dire une configuration de significations imaginaires sociales (SIS) - des "idées-valeurs" générales et "englobantes" - qui fait qu'une société est ce qu'elle est et qu'elle ne pourrait être autrement compte tenu de son noyau de SIS. Ensuite, nous constatons que les travaux d'auteurs importants nous permettent de parler de niveaux et types d'imaginaires sociaux et d'établir des relations entre ces niveaux et formes d'imaginaires sociaux. C'est par l'entremise de la problématique générale agriculture-ruralité que nous démontrons, dans la deuxième partie de cette thèse, que des imaginaires sociaux "intermédiaires" - l'idéologie de l'UPA et l'utopie de la "minorité active", l'UP - permettent, en les ancrant dans quelqu'un et dans quelque chose, d'une part de découvrir les SIS de l'imaginaire social de la société et, d'autre part, de comprendre et d'interpréter ces deux imaginaires sociaux à la lumière des SIS. La problématique agriculture-ruralité est "opérationnalisée" à l'aide des trois dimensions suivantes: rapport à soi, rapport à l'autre et rapport à la nature. Le rapport à soi dévoile que la sphère du travail de l'agriculteur-éleveur dans l'idéologie de l'UPA correspond à la "sphère de la nécessité" qui implique notamment l'hétéronomie des agriculteurs, alors que l'utopie de l'UP la souhaite à la fois comme "sphère de la nécessité" et comme sphère de l'autonomie. Le rapport à l'autre permet de découvrir une utopie préconisant l'égalité des chances entre différents types d'agriculteurs et d'agricultures et entre la relève et les agriculteurs établis ainsi que l'égalité politique en territoire rural agricole. Dans l'idéologie de l'UPA, l'inégalité des chances et l'inégalité politique sont discutables mais inéluctables. Enfin, abstraction faite des nuances, la relation agriculture et nature est à l'utopie de l'UP ce que la relation agriculture ou nature est à l'idéologie de l'UPA. La construction partielle de l'idéologie et de l'utopie, nous permet, dans la troisième et dernière partie de cette thèse, d'y découvrir les SIS et de démontrer que l'utopie trouve son sens et sa cohérence en l'interprétant par l'entremise du naturalisme-écologie, de l'"autonomie" et de l'"autolimitation" comme SIS dominantes et de l'"expansion illimitée de la maîtrise rationnelle" (technique) et du capitalisme (économique) comme SIS "secondaires". Nous découvrons l'inverse dans l'idéologie de l'UPA. Les SIS dominantes et les SIS "secondaires" de l'utopie de l'UP sont respectivement les SIS secondaires et les SIS dominantes sous-jacentes à l'idéologie de l'UPA, ce qui correspond à la configuration des SIS dominantes de l'imaginaire social des sociétés constitutives de l'Occident contemporain.

Trade Liberalization and the Profitability of Domestic Mergers.

It is often thought that a tariff reduction, by opening up the domestic market to foreign firms, should lessen the need for a policy aimed at discouraging domestic mergers. This implicitly assumes that the tariff in question is sufficiently high to prevent foreign firms from selling in the domestic market. However, not all tariffs are prohibitive, so that foreign firms may be present in the domestic market before it is abolished. Furthermore, even if the tariff is prohibitive, a merger of domestic firms may render it nonprohibitive, thus inviting foreign firms to penetrate the domestic market. In this paper, we show, using a simple example, that in the latter two cases, abolishing the tariff may in fact make the domestic merger more profitable. Hence, trade liberalization will not necessarily reduce the profitability of domestic mergers.

The Effect of Agricultural Zoning on Land Prices, Quebec, 1975-1981

Dans Ce Texte Nous Examinons les Effets de la Loi du Zonage Agricole du Quebec, Proclame En Decembre 1978 Sur le Prix du Sol Dans une Banlieu de Montreal. a L'aide de Donnees Sur les Transactions Normales Faites a Carignan et Saint-Mathias de 1975 a 1981, Nous Estimons, a L'aide des Moindres Carrees Ordinaires, une Equation de Determination du Prix Par Acre Avec Comme Variables Independantes la Dimension du Lot, la Distance de Montreal, les Services Disponibles (Egouts,...) et le Zonage Agricole (Ou Non) du Sol. Nos Resultats Nous Indiquent Que le Zonage Agricole Reduit le Prix D'un Acre de Sol.

Land Ownership, Working Capital, and the Agricultural Output: Egypt, 1913-1958.

A simple model is constructed in which short-term credit is needed to finance the purchase of inputs, in which there is bankruptcy risk, and in which we argue were important characteristics of Egyptian agriculture during the first half of this century, result in aggregate agricultural output being dependant on the distribution of land ownership. The main theorical insight is that aggregate agricultural output will be increased by a decrease in the inequality of the distribution of land ownership when returns to scale are decreasing. Testable short- and long-run empirical propositions are formulated and carefully tested on Egyptian data for the 1913-1958 period. We find that, controlling for factor inputs, there is no tradeoff between equity and efficiency for Egyptian agriculture - they go hand in hand in the short run.

Semi-Parametric Weak Instrument Regressions with an Application to the Risk-Return Trade-off

Recent work shows that a low correlation between the instruments and the included variables leads to serious inference problems. We extend the local-to-zero analysis of models with weak instruments to models with estimated instruments and regressors and with higher-order dependence between instruments and disturbances. This makes this framework applicable to linear models with expectation variables that are estimated non-parametrically. Two examples of such models are the risk-return trade-off in finance and the impact of inflation uncertainty on real economic activity. Results show that inference based on Lagrange Multiplier (LM) tests is more robust to weak instruments than Wald-based inference. Using LM confidence intervals leads us to conclude that no statistically significant risk premium is present in returns on the S&P 500 index, excess holding yields between 6-month and 3-month Treasury bills, or in yen-dollar spot returns.

Directed Technical Change and International Trade

Recent changes in comparative advantage in the largest OECD economies differ significantly from the predictions of Heckscher-Ohlin-Vanek theory. Japan's rising share of OECD machinery exports and the improvement in the comparative advantage of the USA and Germany in heavy industry were accompanied by growing scarcities of the factors used intensively in the favored sector of each country. Here we examine Acemoglu's (1998, 2002) hypothesis that technical change may be directed toward raising the marginal productivity of abundant factors. Testing this hypothesis with 1970-1992 export data from 14 OECD countries, we find evidence that international comparative advantage was reshaped by innovation biased toward the abundant factors in the largest economies.

Economic Development under Alternative Trade Regimes

How does openness affect economic development? This question is answered in the context of a dynamic general equilibrium model of the world economy, where countries have technological differences that are both sector-neutral and specific to the investment goods sector. Relative to a benchmark case of trade in credit markets only, consider (i) a complete restriction of trade, and (ii) a full liberalization of trade. The first change decreases the cross-sectional dispersion of incomes only slightly, and produces a relatively small welfare loss. The second change, instead, decreases dispersion by a significant amount, and produces a very large welfare gain.

The Alberta Dilemma: Optimal Sharing of a Water Resource by an Agricultural and an Oil Sector

The purpose of this paper is to characterize the optimal time paths of production and water usage by an agricultural and an oil sector that have to share a limited water resource. We show that for any given water stock, if the oil stock is sufficiently large, it will become optimal to have a phase during which the agricultural sector is inactive. This may mean having an initial phase during which the two sectors are active, then a phase during which the water is reserved for the oil sector and the agricultural sector is inactive, followed by a phase during which both sectors are active again. The agricultural sector will always be active in the end as the oil stock is depleted and the demand for water from the oil sector decreases. In the case where agriculture is not constrained by the given natural inflow of water once there is no more oil, we show that oil extraction will always end with a phase during which oil production follows a pure Hotelling path, with the implicit price of oil net of extraction cost growing at the rate of interest. If the natural inflow of water does constitute a constraint for agriculture, then oil production never follows a pure Hotelling path, because its full marginal cost must always reflect not only the imputed rent on the finite oil stock, but also the positive opportunity cost of water.

Bundling under the Threat of Parallel Trade

This paper examines the use of bundling by a firm that sells in two national markets and faces entry by parallel traders. The firm can bundle its main product, - a tradable good- with a non-traded service. It chooses between the strategies of pure bundling, mixed bundling and no bundling. The paper shows that in the low-price country the threat of grey trade elicits a move from mixed bundling, or no bundling, towards pure bundling. It encourages a move from pure bundling towards mixes bundling or no bundling in the high-price country. The set of parameter values for which the profit maximizing strategy is not to supply the low price country is smaller than in the absence of bundling. The welfare effects of deterrence of grey trade are not those found in conventional models of price arbitrage. Some consumers in the low-price country may gain from the threat of entry by parallel traders although they pay a higher price. This is due to the fact that the firm responds to the threat of arbitrageurs by increasing the amount of services it puts in the bundle targeted at consumers in that country. Similarly, the threat of parallel trade may affect some consumers in the hight-price country adversely.
