Investment criteria for production processes of non-storable goods with periodic demand and constant production constraints

Following Pareto's principles a general economic optimum is worked out for the producer of a non-storable good who has to satisfy a periodic demand with a constant production capacity. It is found that the marginal cost pricing rule applies, with some accommodations when the production capability of the plant is inelastic.A general investment criterion is also obtained, and it is shown that this general criterion can take simplified forms when applied to some well-defined classes of actual production functions.These results should find a broad application in peak-load pricing and in investment policies for such industries as electricity production, railways, telephone, etc.,…, i.e., for producers of non-storable commodities subject to seasonal demand variations.     

At the origin of post-war mainstream of economics: On pareto’s influence on economic theory

Allais (1968) maintained that Pareto’s influence on the development of economics was felt only after considerable delay and was confined to Italy and France. This paper provides a reconstruction of the intellectual dissemination of Pareto’s thought through Europe and the United States in the period 1900–1940, showing that it was influential in the period from c.1900 to the mid-1920s and that in the 1930s it was highly important in the foundation of mainstream post-war economic theory, although in a more elusive way than before.(JEL:B13, B16, B21, B23, B31)     

Consumption and leisure in Austria

Böhm's (1980) data set on consumption and leisure in Austria is used to estimate the Almost Ideal Demand System (AIDS) of Deaton and Muellbauer (1980). Average income elasticities and average Slutzky price elasticities are calculated and the patterns of consumption and leisure in Austria are described.     

Drinking under communism: Why do alcohol consumption habits in Eastern Europe differ from the west in the long-run?

This paper looks into possible explanations for differences between Eastern and Western Europe alcohol consumption behaviour even twenty years after the collapse of the Soviet regime. It suggests these differences can be viewed as an expression of cultural habits. We explore different ways of defining exposure to the communist regime: using number of years a person spent under the regime and also a dummy indicator for spending formative years (18–25) in it. We find both to be strong factors in explaining alcohol consumption behaviour. We consider differences in frequency of alcohol consumption and binge drinking using European Health Interview Survey (EHIS) micro data from Eurostat. Estimations are run with ordered probit model for men and women separately. Evidence suggests a statistically significant effect of experiencing communist regimes, which is larger for women's alcohol consumption frequency than for men's. It is also the most important factor in explaining more frequent male binge drinking. These effects hold after controlling for socio-economic, country level and time characteristics. This suggests the attitudes towards alcohol consumption could be more permissive in the Eastern Bloc countries.     

The energy cost of satisfying basic human needs

This article attempts to estimate how much energy is required to satisfy basic human needs; previous estimates of human energy needs exist but are found wanting. The analysis is based on the Latin American World Model, a simple econometric model that, assuming basic needs-oriented development and certain basic needs targets and considering three developing regions (Latin America, Africa, and Asia), determines per capita income levels at which basic needs are satisfied. Using figures for income and price elasticities of commercial energy demand and for noncommercial energy consumption from the literature, we calculated a range of 27 × 10³ to 37 × 10³ kcal/day per capita for the energy cost of meeting basic human needs. This energy cost range is below current per capita world energy consumption, implying that theoretically all people's basic needs could be met at today's world energy consumption level.     

Pareto and contemporary economic theory

This paper provides explanations for Pareto’s apparently contradictory approach to demand theory in simultaneously insisting that measurability of utility is not needed to explain the equilibrium of consumers in competitive markets, and embracing concavifiability and thus measurability of utility when this implies restrictions on consumers’ behavior such as the law of demand. It also treats his method of calibrating an aggregate demand function by employing his law of income distribution, so as to reproduce “Gregory King’s law”. Finally, some disputed issues are dealt with concerning the nature of Pareto’s contributions to welfare economics. (JEL: B13, D11, D60).     

A comparison of purchasing power parity and consumption levels in Austria and Czechoslovakia

An attempt is made to estimate purchasing-power parity (Par) for a comparison of Czechoslovakia's consumption level with Austria's in 1980. The Par calculation is based on modified official consumer baskets of both countries and the author's own assessment of quality and structural differences. The main conclusion is that economic development in Czechoslovakia was significantly slower than in Austria. A comparison with results of a methodologically similar study of 1964 implies a significant worsening of Czechoslovakia's relative living conditions.     

The dynamics of preference formation

Individual's preferences are explained on the basis of two types of influences, his own past consumption and the consumption of others which is directly observable by him. These effects are estimated using the “individual welfare function” approach of Van Praag, and a model of preferences formation.     

A new approach to the incorporation of attributes into consumer theory

A framework is developed which can be used to analyze a large class of consumption situations which cannot be handled by Lancaster's model. To achieve this end, a certain “expansion” of attribute space is performed. Subsequently, we formally define the notions of mixability and effective number of goods$\text{n}$. This new model degenerates into Lancaster's model for the special case when $\text{n}\text{= 1}$.     

Technological substitution forecasting with a model based on biological analogy

Although many models of technological substitution processes exist, only a few deal with multilevel technological substitution and still fewer may be easily applied to forecasting of real multilevel substitution processes. We propose a stochastic model of multilevel technological substitution and a forecasting method based on this model. In the author's opinion, the developed algorithm may be easily applied to forecasting various technological substitution processes. An example of the application of this algorithm to forecasting of world energy consumption is presented. The algorithm makes possible an investigation of the impact of future innovation on the system's behavior.     

Dynamic behavior of a simple neoclassical model with wealth and capital unequal

The paper analyzes the standard one-good neoclassical dynamic model in which wages to consumer-workers are paid in IOU's issued by producers. The wealth of consumers consists of their accumulated IOU's and the model differs from the traditional one in that it is not assumed that consumers' wealth is exactly equal to the value of the capital stock. The dynamic behavior of this model turns out to be quite different from the traditional one, the main result being that, in the absence of “excessive savings” by consumers, the golden rule will always be the unique stable steady state.     

Estimating labor supply and production decisions of self-employed farm producers

This paper proposes a model oriented towards integrating farm households' production and consumption decisions into a unified theoretical and econometric framework. It is argued that, in contrast with other forms of economic organization, farm households' utility and profit maximization decisions are not likely to be independent.Econometric estimation of a farm-household model using Canadian data suggests that utility and profit maximizing decisions are not indeed independent and, moreover, that there are significant gains in explanatory power and efficiency by estimating the consumption and production equations jointly.     

Asymmetries in price and quantity adjustments by the competitive firm

Focusing on the crucial role of inventory carry-overs in the production and sales decision, we describe the profit maximizing behavior of a dynamic competitive firm facing random prices. Each firm's behavior is incorporated into a stochastic equilibrium model of the competitive industry with uncertain demand. The industry model exhibits asymmetric cyclical fluctuations of the “Keynesian” sort: when demand is weak, output contracts while price holds at a fixed floor; when demand is strong, price increases as output is constrained by a ceiling. Even in a pure world of constant returns, without increasing costs, the inability to instantaneously coordinate production and sales along with the existence of inventories is sufficient to yield a “backward L” shaped supply curve for the short run.     

Balanced equilibrium in a consumption loans model

In a consumption loans model with many generations, Gale's theorem on the existence of balanced equilibrium is generalized, allowing more general preferences. The new theorem shows that there are plausible conditions under which there exists a Pareto optimal (non-optimal) balanced equilibrium whenever there exists (does not exist) a monetary golden rule equilibrium.     

Information processing and jury decisionmaking

We develop a model to explore the information processing function that jury deliberation and its analogues perform. The central question we ask is: How much better could a jury possibly perform if it optimally used the collective information available to it than if it decides cases by a simple majority vote before any deliberation or information sharing occurs? It is shown how the answer depends on a number of considerations, including the correlation among jurors' observations, the jurors' assessments of the relative importance of type I and type II errors compared with society's assessment of those errors, and differences in jurors' abilities.     

Reputation and imperfect information

A common observation in the informal literature of economics (and elsewhere) is that is multistage “games,” players may seek early in the game to acquire a reputation for being “tough” or “benevolent” or something else. But this phenomenon is not observed in some formal game-theoretic analyses of finite games, such as Selten's finitely repeated chain-store game or in the finitely repeated prisoners' dilemma. We reexamine Selten's model, adding to it a “small” amount of imperfect (or incomplete) information about players' payoffs, and we find that this addition is sufficient to give rise to the “reputation effect” that one intuitively expects.     

Rational demand and expenditures patterns under habit formation

This paper proposes a model in which habit formation is present in a relatively general but tractable way. The consumer's problem is transformed into a sequence of two-period Fisherian problems by introducing a “reduced utility function” to ensure full dynamic rationality of the consumer. By making preferences dependent on past real expenditure levels rather than past consumption bundles, it is possible to characterize the long-run behavior of the consumer. Stability analysis is performed. The cases of “immediate habit formation” and “delayed habit formation” are discussed.     

Using long-run consumption-return correlations to test asset pricing models

This paper examines a new set of implications for existing asset pricing models regarding the correlation between returns and consumption growth over both the short run and the long run. The findings suggest that external habit formation models face a challenge in producing two robust facts in aggregate data, namely, that stock market returns lead consumption growth, and that the correlation between returns and consumption growth is higher at low frequencies. To reconcile these facts with a consumption-based model, I demonstrate the need for focusing on models that contain a forward-looking consumption component, i.e., models that allow for both trend and cyclical fluctuations in consumption, and that link returns to cyclical fluctuations in consumption. Long-run risk models provide examples of models that contain this consumption component.     

Insulating countries against fluctuations in domestic production and exports: An analysis of Compensatory Financing schemes

For several years the IMF has operated a Compensatory Financing Facility (CFF) whose aim is to smooth out the effects of a shortfall in export receipts in a particular country. In 1981, the Facility was extended to cover imports of foodstuffs, with the objective of reducing food insecurity. The purpose of this paper is to provide a theoretical analysis of the CFF, interpreted as an international scheme whose object is to stabilise some domestic policy target, such as consumption, by providing loans based on the value or volume of a country's exports or imports. The paper shows that, under certain assumptions, the IMF's CFF for exports provides net gains to individual countries. The extension of the scheme to include food imports could provide further gains, but only if it is appropriately redesigned.
