The French Communication Industry Defined and Analyzed through the Social Fabric Matrix,the Filiere Approach,and Network Analysis

This paper examines the relative impact of economic freedom, civil liberties, and political rights on growth. A system of three simultaneous equations is used to unearth the channels through which these institutional dimensions affect economic growth. These include greater efficiency and enlarged investment in physical and human capital. The sample contains 79 countries and six periods covering the years from 1976 to 2005. The results show that the three dimensions of institutional quality are important for economic growth either through a better allocation of resources or, indirectly, through the stimulation of investment in physical and human capital.     

Volume XXXIV – 2000

In the attempt to deepen the understanding of Keynes' thought as an international macroeconomist, we explore the hypothesis of consistency between his general methodological approach to the economic material and his way of reasoning about international economic relations. As a first step toward this direction, we investigate the methodology of The Economic Consequences of the Peace and find that it reflects Keynes' attempt to cope with the attributes of the complexity characterizing the European settlement for the post-war period, e.g., 1) organic interdependence among variables at play, 2) irreducible dilemmas and situations of conflict, as well as 3) the need for external, public assistance to overcome the impasse and promote a "shared responsibilities" approach to the imbalances. Striking similarities appearing with the method of Keynes' economic diplomacy in the 1940s are shown to substantiate the current rediscovery of his plans for Bretton Woods.

The effect of taxation on labour supply: the case of moonlighting

The authors provide a simple test of supply-side economics by estimating the responsiveness of moonlighting labour supply to changes in the marginal tax rate and the wage rate. While standard theory teachers that changes in taxes and wage should have opposite and equal effects on labour supply, taxes affect the entire asset position of the household. In the short run, an adjustment of hours in the second job may be the only option available to an individual in responding to a tax change. Thus, analyses based on after-tax wages may understate supply-side effects. To estimate these effects a tobit procedure is employed. The empirical results suggest a backward-bending supply curve over thet range of moonlighting hours. Data consist of a subsample of male blue-collar workers from the 1978 cross-section of the Panel study of Income Dynamics.     

Productivity change in Canadian mining 1957–1979

This paper calculates multifactor productivity trends in seven Canadian mining industries and relates changes in productivity to various factors, including changes in output and factor prices and the decline in the quality of the ore being mined. It is found that productivity decline in mining has been pronounced and tended to predate that of manufacturing by several years. There are indications that the most important factors in the decline have been the fall in mineral grade, contraction of output, increases in interest rates and an apparent decline in the rate of technical innovation.     

Constrained output maximization and US agriculture

This paper presents a framework for estimating an indirect production function and then applies it to aggregate US agriculture. Issues addressed include tests of standard hypotheses about the underlying technology (homotheticity, neutral technical change, etc.) as well as examination of consistency in aggregation and the effects of changes in the level of aggregate expenditure on farm output. Since there already exist several studies empirically describing agricultural production technologies with indirect objective functions, one might fairly ask whether this paper really breaks any new ground? We feel that it does. One reason is that existing studies (e.g. Binswanger, 1974; Lopez, 1980; Ball and Chambers, 1982; Ray, 1982; and Weaver, 1983) all rely on either profit or cost functions. To date there appears to be only one study using an indirect production (Appelbaum, 1979), and it is not in agriculture. This seems unfortunate because there are many instances in agriculture for which an indirect production function (or revenue function approach) seems more appropriate. The reason why relates directly to one's belief about the objective function and constraints farmers face. Ultimately, it seems plausible in a certainty framework that producers maximize profits. And since cost minimization and output maximization are just constrained versions of profit maximization, both cost and indirect production functions are more appropriately viewed as restricted profit functions. What differs is the constraint. Assuming cost minimization implies that farmers are constrained by a fixed output which they must produce; in most instances, this is implausible. More likely, the level of output is itself a choice variable. Output maximization, on the other hand, suggests that the main constraint is the amount of money that producers can muster to hire resources. In other words, farmers may face binding constraints in obtaining the profit maximizing level on expenditure on input utilization. One might think that expenditure may not be a binding constraint because there exists a relatively active US credit market. However, the US credit market is far from being perfectly competitive in a stylized sense, and thus, the possibility of a farmer being able to finance a given level of expenditure may be limited.

Readers familiar with the dual approach to production problems may already be asking why these ideas rule out cost functions since it is well known that the cost function is the distance function of the indirect production function (Blackorby et al., 1978)? In principle, therefore, one could always estimate a cost function and then invert it to obtain the indirect production function. There are two problems with this approach: the first is that if output maximization is truly the objective, output is not predetermined and cannot be treated as exogenous in cost function estimation. Second, estimation of direct and indirect functions using the same data set does not always yield comparable results. Estimation of a transcendental logarithmic (translog) indirect production function and a translog cost function, separately, does not generally yield identical estimates of the Allen elasticities of substitutions. Solving the first problem in simple, but the second suggests that estimation should proceed on the basis of the objective function the researcher deems most appropriate. Therefore, if output maximization is more plausible than cost minimization an indirect production function should be used.

The plan of the paper is as follows. We first outline the theoretical developments necessary to our approach (included are conditions necessary for consistent aggregation over firms). We then present estimates of an indirect production function and use these estimates to investigate the plausibility of various restrictions on the technology, consistency in aggregation, substitution possibilities in agricultural production, and the effect of expenditure on agricultural input utilization. The paper closes with a discussion of the results and suggestions for future research.
