Enhanced co-citation analysis using frameworks

The valuation of intangible assets, such as patents, has recently been considered an important technique for R&D strategies. This paper proposes a citation analysis as a method of valuation on patent clusters having patent networks. A citation analysis is a method that examines the value of a patent on the basis of the number of citations of references. In particular, a co-citation analysis is used for coupling patents as the patent cluster and valuating the patent cluster. While the co-citation analysis is of great interest as a method of valuation, this analysis has not been fully examined and does not define any framework for a technology transition and patent strategy. Therefore, in this paper, the conventional co-citation analysis for evaluating the patent clusters is enhanced and frameworks for the technology transition and patent strategy are proposed by analysing citation routes in a co-citation analysis.     

Choice of Techniques in Non-proportionally Growing Economies: a Note on Pasinetti's Analysis

This paper discusses which technology is efficient for non- proportionally growing economies. Pasinetti (1988) claims that if each vertically hyper-integrated sector uses such a set of techniques that the economy chooses if the profit rate equals the growth rate of the sector, the chosen set of techniques is the most efficient for the non-proportionally growing consumption demand. This paper demonstrates that there may exist a more efficient choice of techniques than Pasinetti mentions. This result also implies that if more efficient techniques are invented, economies may have to change techniques gradually rather than immediately.     

Capital Imports and Tariffs

This paper develops a three‐sector, three‐factor specific factor model with a tariff and presents conditions under which capital imports and tariffs can be welfare enhancing in a developing country. The impact on welfare depends on the tariff revenue effect and the repatriation effect. A capital import is welfare enhancing if it reduces the domestic output of imports. A tariff is welfare enhancing only if it reduces the return to foreign capital.     

On the new export sector in developing countries

Abstract

Many developing countries are establishing a new export sector by accepting foreign direct investment. Developing a three-sectors three-factors general equilibrium model with tariff, this paper considers the condition under which the acceptance of direct investment is desirable for the developing countries. We show that the factor intensity rankings among the sectors play a key role on the welfare effects and that direct investment increases the output of both the new export and the traditional export sector and promotes the export-led growth in developing countries.     

THE MODIFICATION OF PASINETTI'S DYNAMIC LABOUR THEORY OF VALUE

This paper discusses how much labour is directly or indirectly necessary for present or future consumption of each commodity. Defining a vertically hyper-integrated labour coefficient for every commodity. Pasinetti claims that it represents the labour which is dynamically necessary for a unit consumption of the commodity. However, if technology and annual growth rates of consumption demand are given, vertically hyper-integrated labour coefficients are not determined uniquely. This paper demonstrates this result and formulates the improved vertically hyper-integrated labour coefficients which are determined uniquely and thus readily applicable to both theoretical and empirical study of technical progress in non-proportionally growing economies.     

A note on the wise girls puzzle

Summary. This article analyzes the two wise girls puzzle, which is a simpler variant of the so-called three wise men puzzle, with some proof-theoretic tools. We formulate the puzzle in an epistemic logic. Our chief assumption is that the reasoning ability of each player of the puzzle is equivalent to what is described by the epistemic logic. We will interpret the behaviors of the players in the puzzle in terms of unprovability of certain statements. The proof-theoretic tools we employ are consequences of a meta-theorem, known as the cut elimination theorem. Received: August 1, 2000; revised version: May 15, 2001     

A Model of Welfare Enhancing Capital Imports

This paper proposes a model of welfare enhancing capital imports in a multi‐dimensional framework. Contrary to the pessimistic conventional wisdom of capital imports and welfare, a justification is provided for the acceptance of foreign capital in developing countries.
