ABSTRACTWe introduce well‐known microeconomics productivity measures in Solow models in discrete time or continuous time by adopting a Luenberger‐type approach. In each framework, we derive the productivity indicators and the dynamical paths. First, we show that the expression of the productivity indicators are similar to the well‐known Solow residuals, allowing us to make an analogy between a firm's behavior in a microeconomic setting and a country's behavior in a macroeconomic setting. Second, we demonstrate that the properties of the paths are similar in both frameworks.

This paper investigates the economics of uncertainty using a state‐contingent approach with a focus on the role of non‐convexity. Under efficiency, the slopes of a separating hypersurface measures state‐contingent prices. As argued by Yaari, normalized state‐contingent prices provide a measure of subjective probabilities. But efficiency under non‐convexity can require non‐linear pricing. The analysis identifies non‐convexity conditions under which probability assessments are not appropriate. Implications for economic and welfare analysis under uncertainty are discussed.

ABSTRACTGeneralizing earlier approximation results, we establish exact relations between the Luenberger productivity indicator and the Malmquist productivity index under rather mild assumptions. Furthermore, we show that similar exact relations can be established between the Luenberger–Hicks–Moorsteen indicator and the Hicks–Moorsteen index.

Production frontiers for the manufacturing sector are estimated to determine a "country specific" catching-up
process of Total Factor Productivity (TFP).TFP gains were aimed at assessing the manufacturing industry's productive performances for 14 OECD countries over the period between 1970-2001. Our TFP measure does not assume technical or allocative efficiency which are inherent drawbacks of usual TFP indices. We show that catching-up processes can be very different between sub-periods and across countries. A significant catching-up process was in progress in the manufacturing sector between 1970 and 1986 then it overturned over the period 1987-2001. During the first sub-period, the speed of technological catching-up of the euro-zone countries was definitely higher than those of the other European or OECD nations whereas the divergence noted in second subperiod
had the same order of magnitude amongst the three groups..
