AN INPUT-OUTPUT APPROACH TO THE MEASUREMENT OF PRODUCTIVITY DIFFERENCES

This paper deals with the measurement of efficiency differences among countries within a federation. The key tool is the use of a suitable interpretation of the non-substitution theorem in order to get a natural technological standard. Two alternative indices are proposed. One provides a structural productivity measure, independent of consumption and prices. The other consists of a price index associated with the equilibrium aggregate demand.Input-Output Analysis; Nonsubstitution Theorem; Measurement of Productivity

MULTIDIMENSIONAL INEQUALITY AND SOCIAL WELFARE

This paper provides a cardinal welfare measure for the allocation of a bundle of goods among a group of people. Social welfare is measured as the sum of n partial indices, one for each good, each of which consists of a function of the amount of the good availabe and its dispersion, measured by Theil's first inequality index. Some applications of this welfare measure are also suggested.Inequality and Welfare; Social Goods; Cardinal Welfare Measures.

- VALUATION EQULIBRIUM REVISITED

This paper extends the notion of valuation equilibrium which applies to market economies involving the choice of a public environment. Unlike some other recent work, it is assumed here that consumers and firms evaluate alternative environments taking market prices as given (hence this notion is closer to that of competitive equilibria). It is shown that valuation equilibria with balanced tax schemas yield eficient allocations and that eficient allocations can be decentralized as valuation equilibria, with tax schemas that may be unbalanced.valuation equilibrium, non-convexities, public goods

EFFICIENCY AND CORE PROPERTIES OF VALUATION EQUILIBRIUM WITH INCREASING RETURNS

This paper considers market economies involving the choice of a public environment when there are nonconvexities in production. It discusses the decentralization of efficient allocations by means of valuation equilibrium, adapting to many private goods the notion due to Mas-Colell (1980) which extends the Lindahlian approach to the pure theory of public goods. It is shown that a valuation equilibrium satisfies the two welfare theorems and is in the core.Valuation Equilibrium, Increasing Returns to Scale, Efficiency.

THE THREE MUSKETEERS: FOUR CLASSICAL SOLUTIONS TO BANKRUPTCY PROBLEMS

This paper provides a comparative analysis of some classical solutions to bankruptcy problems from an axiomatic viewpoint. These rules are the constrained equal-awards rule, the constrained equal-losses rule, the proportional rule and the Talmud rule. The purpose of this study is to facilitate the understanding of their differences and to clarify the type of situations in which each of these rules is better.Bankruptcy problems, proportional solution, equal-awards solution

Del anteojo a la óptica adaptativa

Buena parte de lo que conocemos del universo se debe a lo que se aprecia a través de los telescopios, pero estos no siempre han tenido la misma forma, ni la misma precisión. Desde que por primera vez Galileo utilizara un anteojo en el siglo XVII éste no ha dejado de evolucionar

THE TALMUD RULE AND THE SECUREMENT OF AGENTS? AWARDS

This paper provides a new characterization of the Talmud rule by means of a new property, called securement. This property says that any agent holding a feasible claim will get at least one nht of her claim, where n is the number of agents involved. We show that securement together with a weak version of path independence and the standard properties of self-duality and consistency characterize the Talmud rule.bankruptcy problems, Talmud rule, characterization results

Pemodelan Farmakokinetika Berbasis Populasi dengan R: Model Dua Kompartemen Ekstravaskuler: Population-Based Pharmacokinetics Modeling With R: Two Compartment Extravascular Model

A Tutorial of two-compartment extravascular population-based pharmacokinetics modeling was performed by differential equations and non-linear mixed effect model approach. First, three-level differential equations of two-compartment pharmacokinetics were generated. Then, covariate and non-covariate models were developed by nlmeODE and nlme packages installed in R. The best model was selected according to AIC, BIC, and LogLik value. A model without covariates model was selected as the best model. The selected model showed a goodness of fit with experimental dataset and residual plot of the model revealed that no violations of model assumtions.  In conclusion, nlme and nlmeODE is capable to generate an adequate predictive model of two-compartment population-based pharmacokinetics for extravascular rout
