An axiomatic characterization of a generalized index of concentration

The Hannah-Kay [1977] generalized concentration index contains the well-known Herfindahl [1950]-Hirschman [1945] and the entropy indices as particular cases. In this papaer we show that the Hannah-Kay class can be regarded as a particular member of a generalized family of indices, which we refer to as self-weighted quasilinear means. We then show that among all self-weighted quasilinear means the Hannah-Kay family is the only class of concentration indices which satisfies the replication principle, a requirement which states that an m-fold replication of the industry, firm by firm, will multiply the concentration index by the factor 1/m.The refereeing process of this paper was handled through N.R.

The role of stochastic volatility and return jumps: reproducing volatility and higher moments in the KOSPI 200 returns dynamics

This paper investigates the role of stochastic volatility and return jumps in reproducing the volatility dynamics and the shape characteristics of the Korean Composite Stock Price Index (KOSPI) 200 returns distribution. Using efficient method of moments and reprojection analysis, we find that stochastic volatility models, both with and without return jumps, capture return dynamics surprisingly well. The stochastic volatility model without return jumps, however, cannot fully reproduce the conditional kurtosis implied by the data. Return jumps successfully complement this gap. We also find that return jumps are essential in capturing the volatility smirk effects observed in short-term options.

The implications of private tutoring on the school education in LDCs

In many LDCs, we observe that the public school teachers receive low wages, expend less than their full effort at school, and provide private tutoring to the students for a fee. To capture this institutional arrangement, we develop a theoretical model which shows that in comparison with ‘no-tutoring’, ‘tutoring’ is welfare reducing for all students in the economy. However, if the government considers only the students in the public system, then ‘tutoring’ can be welfare improving. In that case, the government would set a lower tax rate to pay wages to the teachers and let them provide tutoring to the students for a fee.

Regulating prices for shifting between service providers

The price that a regulated access provider charges for shifting customers between service providers has significant welfare implications. Typical regulatory approaches to pricing, such as pricing based on fully allocated cost or incremental cost, ignore the characteristics of consumer demand. A theoretical alternative, Ramsey pricing, considers only the elasticity of demand for given products. This paper directs attention to the competitive process. Using US long-distance telephone services as an example, this paper shows how empirical evidence concerning customer acquisition costs, customer switching costs, and churn among service providers can help to inform price regulation.     

Stochastic Growth Models and Their Econometric Implications

This article considers the consequences of explicitly allowing for stochastic technological progress and stochastic labor input in the discrete-time Solow-Swan and AK growth models. It shows that the capital-output ratio, but not output per capita, is ergodic irrespective of whether there is a unit root in technology, and thus is the more appropriate measure to use in the cross-sectional analysis of the growth process. Furthermore, the article derives the cross-sectional and time-series implications of the stochastic Solow-Swan model and contrasts these to those of its deterministic counterpart. Among these implications are that the mean of the capital-output ratio depends in a precise way not only on the saving rate and the growth rate of labor input, but also on the variance and higher-order cumulants of the capital-output ratio. Using the Summers-Heston data for seventy-two countries from 1960 to 1992, strong support is found for the predictions of the stochastic Solow-Swan model as compared to those of its deterministic counterpart (as well as those of the AK model), including a significant negative cross-sectional relationship between the mean and the variance of the capital-output ratio.     

Eighteenth-Century Evolutionary Thought and its Relevance in the Age of Legislation

This essay revisits the evolutionist writingsof the eighteenth century to clarify their key ideas concerninglegal and social evolution and to assess their relevance in thepresent era of pervasive legislation. The discovery of the principleof the accumulation of design is traced to these writings andthe continuity of twentieth century spontaneous-order theoryand new institutional economics with this tradition is noted.While highlighting the contributions of other institutional theoriststo the elucidation of the role of purposive action in legal evolution,the author argues that input designing does not alter the fundamentalnature of legal emergence as postulated by the eighteenth centuryscholars. The essay supports the ideal of legal generality, freespeech, property and contractual freedom as normative implicationsof the evolutionary viewpoint.
