In This Paper We Present and Implement an Econometric Test of Both Negative Semi-Definiteness of the Matrix of Compensated Price Effects and of the Negative Quasi-Definiteness of the Matrix of Uncompensated Price Effects. This Test Allows Us to Evaluate Two Alternative Characterizations of...

In This Note, We Explain Why Comparing the Total Factor Productivities of Extractive, and Non Extractive, Sectors Is Likely to Be Misleading; Then We Propose a Correction and Implement It for the Cas of Asbestos, Where It Turns Out to Make a Significant Difference.

In Order to Compute an Index of Total Factor Productivity, It Is Necessary to Know Returns to Scale and Interval Valuations of Quasi-Fixed Factors; Neither Are Directly Observable. in Resource Industries This Problem Is Compounded by the Facts That Returns to Scale Are Important and That There...

This Note Presents a Necessary and Sufficient Condition for All Goods to Be Normal, in the Case of Differentiable Individual Demand. This Condition Appears As a Relationship Between the Quantity Effects on Marginal Willingness to Pay and Is Consequently a Characteristic of the Preference Order....

In This Note, We Present the Appropriate Forms of Shephard's Lemma, As Well As the Curvature and Homogeneity Properties, for the Case of a Rate-Of- Return Regulated Cost Function Where Capital Is a Quasi-Fixed Input.

In This Note, We Shall Demonstrate a Slight Extension of the Envelope Theorem and Use It to Prove That an Intertemporatl Economy Can Be Spanned Or Represented by a Sequence of Temporary Economies, Each of Them Preserving the Geometrical and Analytical Structure of the Previous One.

Ce Texte Constitue un Survol des Differentes Approches Destines a Mesurer le Progres Technique. Nous Utilisons une Notation Uniforme Tout au Long des Demonstrations Mathematiques et Nous Faisons Ressortir les Hypotheses Qui Rendent L'application des Methodes Proposees Envisageable et Qui En...

Corporate finance theory predicts that firms' characteristics affect agency costs and hence their efficiency. Cummins et al. (2006) have proposed a cost function specification that measures separately insurer efficiency in handling risk pooling, risk management, and financial intermediation...
