Public and private Investment in Mexico and Chile: An empirical test of the complementarity hypothesis

This paper addresses the important question of whether government investment spending, rather than overall public expenditures, exerts a positive effect on economic growth and productivity. Using time-series data for Chile and Mexico, it estimates a linear growth model that incorporates a number of relevant quantitative and qualitative variables for each country. The empirical results suggest that for both Chile and Mexico, increases in public and private investment spending have a positive and significant effect on the rate of growth in productivity. Moreover, the results for Mexico show that increases in government consumption expenditures have a negative effect on the rate of productivity growth, thus suggesting that the composition of government spending is at least as important as the growth rate of these expenditures in affecting economic growth. From a policy standpoint, these findings call into question the current trend among Latin American countries of indiscriminately reducing public spending because they fall disproportionally on capital expenditures—the type of spending needed to secure the long-term efficiency gains from market-oriented programs.

A Sufficient Condition for Generalized Lorenz Order

In this paper, a sufficient condition for non-negative random variables to be ordered in the Generalized Lorenz sense is presented. This condition does not involve inverse distribution functions. Applications of this result to several income distribution models are given. Journal of Economic Literature Classification Numbers: D36, D69.     

Marx's Theory of Ground Rent: A Critical Assessment

This critical essay provides the reader with an up-to-date assessmentof Marx's relatively neglected theory of absolute ground rentby bringing together in a coherent manner his scattered observationsand arguments contained primarily in Capital, Vol. III and Theoriesof Surplus Value, Vol. II. It also reviews the extant secondaryliterature which suggests that within Marx's theory of rentis an embryonic theory of monopoly from which scholars can drawimportant insights into the history of economic thought andthe workings of mature capitalism. The paper is organized asfollows. After an introductory section, Section II providesthe reader with an overview of Marx's theory of differentialrent and compares it to that of Ricardo, particularly Marx'sdiscussion of differential rent II and whether nature is productiveof exchange value. Section III discusses Marx's theory of absoluterent in light of recent criticisms by prominent scholars andsuggests that what determines whether rent is paid on the marginalland is not technical backwardness or lower productivity oflabor per se, but a social relation, viz., the monopoly createdby the private ownership of land. The last section summarizesthe main arguments and suggests some avenues for future research.     

Wild cards, weak signals and organisational improvisation

This paper addresses the need for reliable action guidelines which can be used by organisations in turbulent environments. Building on current conceptual and empirical research, we suggest an analytical approach to the management of surprising and potentially damaging events. In order to do so we propose the wild card management system. Wild cards refer to sudden and unique incidents that can constitute turning points in the evolution of a certain trend. As the first of the two components of such a wild card system, we advocate a weak signal methodology to take into account those wild cards that can be anticipated by scanning the decision environment. The second component, the nurture of improvisation capabilities, is designed to deal with unanticipated ongoing crises. This paper can be seen as part of a broader agenda on how to manage in conditions of continuous but unpredictable change.

Women,men and organic food: differences in their attitudes and willingness to pay. A Spanish case study

The main purpose of this work consists of displaying the different attitudes of men and women towards organic food, and their willingness to pay for it, in three different consumer intensities: usual, occasional and potential consumers. Several surveys have been carried out to obtain a representative sample of regular food purchasers living in Castilla‐La Mancha (Spain). Statistic analysis previously detecting significant differences with regard to gender and type of consumer has been conducted by univariate analysis to describe attitudes, and multivariate analysis, through ‘logit’ models, to calculate maximum willingness to pay. Results show that women have a more favourable attitude (directly related to their lifestyle) to the purchase and consumption of organic food than men, whereas men are inclined to pay a higher price for organic food than women. In general, men are disposed to pay a higher increase in price than women.     

IS ECONOMIC GROWTH GOOD FOR THE POOR? TRACKING LOW INCOMES USING GENERAL MEANS

We propose the use of an alternative methodology to track low incomes based on Atkinson's “equally distributed equivalent income” functions or “general means” and present a new characterization to justify their application. To evaluate the effects of growth on lower incomes, growth rates are compared for two income standards: the ordinary mean and a low‐income‐sensitive general mean. The question is: How closely related are these two variables? After estimating the growth elasticity, we find that it is not significantly different from zero. Thus, it cannot be concluded that poorer incomes grow proportionately to increases in the average income.     

Spatial heterogeneity and interregional spillovers in the European Union: Do cohesion policies encourage convergence across regions?

Using a spatial econometric perspective, the speed of convergence for a sample of 163 regions of the European Union (EU) over the period 1981–1996 is estimated. For this purpose, we use a specification strategy which allows an explicit modeling of both spatial heterogeneity and spatial autocorrelation found in the analyzed sample. The estimated final model combines groupwise heterocedasticity, the identification of two spatial regimes and spatial dependence. Our results show how an appropriate consideration of the role of spatial effects can shed new insights into the European convergence process. We find that regions in the EU cohesion-fund countries (Ireland, Greece, Portugal and Spain) are converging separately from the rest of regions of the EU. Our estimations indicate that over the analyzed period, there was a faster conditional convergence in relative income levels of the regions belonging to Cohesion countries (5.3%) than in the rest of the regions of the EU (3.3%). Therefore, our results contrast with other evidence that points to the fact that the convergence process in Europe has weakened or even has stopped at the beginning of the 1980s. Moreover, our work shows clear evidence of separate spatial convergence clubs among EU regions.
