Refinery mix in the U.S., Canada,and the E.E.C.

This paper examines the response of gasoline's share of a barrel of crude oil to changes in relative petroleum product prices. An inter-country comparison of the U.S., Canada, and the E.E.C. allows investigation of different parts of the production possibility frontier. In the U.S. and Canada, with relatively large amounts of cracking capacity, there is price responsiveness of the product mix to changes in relative product prices. In the U.S., both residual and distillates are substitutes in production for gasoline, but for Canada, only distillate is a substitute. Part of this difference is attributed to the U.S. oil quota. For the E.E.C. with relatively small amounts of cracking capacity there was no discernible effect of product prices on product mix.     

Determinants of U.S. direct investment in the E.E.C.: Revisited

This paper expands upon an earlier work in this Review concerning the specification of a model to identify the determinants of U.S. direct foreign investment (DFI) in the E.E.C. Compared to earlier studies, a longer data series is used, an improved tariff discrimination proxy is employed, and ‘predicted sales’ are estimated and used as the output variable in the empirical work. A variable to capture the effect of the U.S. capital control programs is also included. The findings reaffirm the importance of market size, especially in the plant and equipment equations, as being an important determinant of DFI. Strong support was also found for the growth hypothesis. Consistent statistical support was found for the tariff discrimination hypothesis. In addition, the findings imply that a variable to capture the effects of fluctuating exchange rates should be included in future studies.     

Determinants of U.S. direct investment in the E.E.C.: Further evidence

This study attempts to identify the determinants of U.S. direct foreign investment in the E.E.C. Previous studies are examined and an alternative specification is presented. The results indicate that the size of the market, growth of the market, height of trade barriers, and lagged net plant and equipment expenditures are important. Even so, the author feels that the data is too weak to permit strong policy statements from being made, as has been done in some of the previous papers.

An account of the Washington Lend Lease negotiations 1944 by E. A. G. Robinson

In September 1944, John Maynard Keynes set sail for Washingtonwhere Keynes was to be a key negotiator in the talks leadingup to Stage II of Lend Lease. Accompanying him and his wifewas Keynes's colleague and friend, E. A. G. (Austin) Robinson.Robinson's role was to be Head of Programmes Division for theMinistry of Production. While Keynes would deal with Harry Whiteand Henry Morgenthau, Robinson was involved with the underlyingproduction of a case for the urgent financial needs of war-timeBritain. Robinson saw the tensions at all levels of daily lifeand he recorded his demanding times in a series of letters hometo his wife, Joan Robinson. These letters are published herefor the first time.     

ECONOMIC ACCOUNTS FOR DEVELOPING COUNTRIES

This paper has three parts. The first part attempts to analyse the prevailing situation in developing countries. The second part presents a feasible accounting system for such countries, by and large within the framework of the SNA. The third part goes beyond this and tries to obtain a more concise matrix (covering, in concept, those given in the accounting system) furnishing minimal sets of variables and classifications which one has, in any case, to play within the context of policy issues of developing countries. All three authors are jointly responsible for the first part. Uma Datta Roy Choudhury has drafted the second part. The third part has been drafted by the other two authors.

C.E.S. production functions in the light of the Cambridge critique

The Cambridge debate of the 1960s showed conclusively that the aggregation of capital, so as to obtain a surrogate production function according to Samuelson, is not possible in general, with critical implications also for other variants of neoclassical theory. The framework for the demonstration is that of linear activity analysis.There is an individual wage curve in function of the rate of profit for each technique. If these individual wage curves were straight lines, their envelope would define a wage curve resulting from all techniques, from which a surrogate production function could be derived, but all wage curves are straight only, if there is only one industry. And if wage curves are not straight, phenomena such as reswitching show that essential neoclassical hypotheses need not hold. A recent empirical investigation by Han and Schefold has found one empirical example for reswitching and several for reverse capital deepening.A rigorous derivation of surrogate production functions thus is ruled out also on empirical grounds, but the paradoxes seem not to be as frequent as the critics once thought, so that the question arises whether approximate surrogate production functions could be derived, with individual wage curves which would be sufficiently linear to construct approximate surrogate production functions, indicating a relationship between the intensity of capital and output per head which would be sufficiently precise to work with.The paper is part of a wider investigation, in which conditions for the existence of quasi-linear wage curves and the possibility of the construction of approximate surrogate production functions are given. The emphasis here is on the special hypotheses needed to obtain C.E.S. production functions.     

Business ethics in America: A view from the classroom

In the first part we explored the views of business executives; the second part analyzes the beliefs and values of business educators; and the third part will compare and contrast the responses from academic and business leaders.     

The relationship between saving and finance: theory and evidence from E.U. countries

This paper investigates the relationship between saving and investment in an effort to shed light on the issue of mobility of capital and whether or not this is prevented by the presence of any barriers. The data of our analysis are annual and come from 14 E.U. countries during the 1960–1994 period. The econometric analysis shows that for the E.U. countries, saving and the provision of credit are two cointegrated variables, which means that for each E.U. country (Belgium was the only exception) the amount of money saved is closely related to the amount of money that is ultimately invested. This result lends support to the view that in E.U. countries the degree of capital mobility plays a minor role in investment, which is primarily influenced by the conditions affecting the domestic provision of savings. In addition, the econometric analysis shows that the causal linkage is in most countries from savings to investment.

The structure of Say's economic writings

The present paper establishes a general picture of Say's economic thought. The first part provides a general view of Say's writings stressing his economic publications other than the Traité, and the non-economic publications covering two other realms of what was labelled the Sciences morales et politiques in France at that time. The second part is devoted to the Traité since this theoretical piece belonging to Classical political economy has a history throughout its various editions. Finally, the third part considers Say's second great book in economics, the Cours complet d'éeconomie politique pratique and explains the reasons why he wrote it.     

A.S.E. events

We are experiencing a situation of increasing criticism of the state in which economics is being represented nowadays. One of the remarks is that economics has become too formalized and too abstract and that the state of discipline has become increasingly unable to express many phenomena of “real life” with its concrete socioeconomic specifica. Criticism has found a way to get cumulated in different terms of economic pluralism. The claim for fostering interdisciplinary research which we also find nowadays reflects the diagnosis that our islands of shared knowledge have become too fragmented. When reflecting what is going on in recent times a view back to the end of the nineteenth century may help to contextualize recent debate. Looking at the debate between Carl Menger and Gustav Schmoller which was later classified as the first battles in social sciences helps to sort up arguments which are still on the agenda, inductive versus deductive methods or empirism versus abstract theorizing.     

Lucas on involuntary unemployment

The aim of this paper is to examine critically Lucas' argumentsagainst Keynes's General Theory and in particular against Keynes'sconcept of involuntary unemployment. It comprises two main parts.In the first part of the paper, the author questions Lucas'sclaim that Keynes betrayed the equilibrium discipline by freeinghimself from the postulates of optimising behaviour and marketclearing. In the second part, Lucas’ three arguments againstthe involuntary unemployment concept are discussed—first,that there is no rationale for drawing a distinction betweentwo sorts of unemployment; second, that every economic outcomefeatures the voluntary and the involuntary jointly; and third,that alternatives to unemployment are always present.

NOUVEL ESSOR DES FONDATIONS AU QUÉBEC ET AU CANADA: POUR UNE ANALYSE SOCIOPOLITIQUE FONDÉE SUR LE CONCEPT D'ÉCONOMIE PLURIELLE

Philanthropic foundations are the object of little research in Canada and Quebec. Our article recognizes the role of these organizations, as well as the presence of powerful new foundations, rich in assets and donations. This article consists of three parts. The first part presents a theoretical review of the American literature published from 2000 on. The second part examines data that we extracted from three main repertoires. Though informative, these repertoires tend to classify Canadian and Quebec foundations in categories that are mostly fiscal and legal and tend to break them down as public or private foundations. We therefore question the limits of studies based on such categories. In the third part of the article we propose a theoretical framework based on a sociopolitical point of view in an attempt to transcend the binary approach. Our approach borrows from the concepts of social and solidarity economy (SSE) and plural economy in order to better understand the new institutional arrangements in which foundations operate. This theoretical framework allows us to analyse foundations as actors of the SSE even though they might not reproduce automatically the principles and the values of the SSE in their behaviours. On the contrary, from the standpoint of a plural economy we may be in a better position to develop a sound sociopolitical analysis of diverse configurations and hybrid forms resulting from emulations or transactions between the principles of the social and solidarity economy (reciprocity), the private economy (competition) and the public economy (redistribution).     

Inventories and the Business Cycle: Testing a Sequential Trading Model

The uncertain and sequential trading (UST) model of inventories behavior with iid shocks predicts that (a) the beginning of period inventories is a sufficient statistic for past variables and (b) an increase in the beginning of period inventories reduces output, employment, hours per employee, and effort. I find empirical support for the second hypothesis but not for the first. The rejection of the first hypothesis is rather informative and points in the direction of adjustment costs and/or serially correlated shocks.
