Soviet Household Saving Function

In this paper, the Soviet household saving function is estimated using reconstructed data from the unpublished archival material: the Soviet family budget survey data. In addition, a shortage indicator is developed to capture both household purchasing power in comparison with the availability of consumer goods in the official market and the spillover of the household demand for consumer goods from the official retail market to the secondary one. A long-run solution of the Soviet household saving function, which includes a shortage indicator as one of the independent variables, is estimated using these data. The reliability of the long-run solution is confirmed by the short-run dynamics of the Soviet household saving function, which satisfy super-exogeneity, parameter constancy, and several diagnostic tests. The highly significant coefficient of the shortage indicator suggests that Soviet household saving behaviour was affected by shortages of consumer goods during 1965–1989.

Trade-offs in the allocation of prosecution resources: an opportunity cost of overcriminalization

One in every five citizens has a criminal record in Korea. Scarce prosecution resources have been severely skewed toward prosecuting more ‘legislated crime’ than ‘conventional crime’. We estimate the opportunity cost of this prosecutory pattern in terms of spillovers to conventional crimes. The cost was found to be substantial. For example, in 2003, the total spillovers accounted for approximately 25% of the increase in conventional crimes for 3 years from 2000 because of the disproportionate prosecutory focus on legislated crimes compared with that of the 1990s. This article has relevance to those countries with an overcriminalizing trend for legislated crimes.     

Full versus quasi MLE for ARMA-GARCH models with infinitely divisible innovations

We compare the backtesting performance of ARMA-GARCH models with the most common types of infinitely divisible innovations, fit with both full maximum likelihood estimation (MLE) and quasi maximum likelihood estimation (QMLE). The innovation types considered are the Gaussian, Student’s t, α-stable, classical tempered stable (CTS), normal tempered stable (NTS) and generalized hyperbolic (GH) distributions. In calm periods of decreasing volatility, MLE and QMLE produce near identical performance in forecasting value-at-risk (VaR) and conditional value-at-risk (CVaR). In more volatile periods, QMLE can actually produce superior performance for CTS, NTS and α-stable innovations. While the t-ARMA-GARCH model has the fewest number of VaR violations, rejections by the Kupeic and Berkowitz tests suggest excessively large forecasted losses. The α-stable, CTS and NTS innovations compare favourably, with the latter two also allowing for option pricing under a single market model.     

A Taxonomy of Industries Based on Knowledge Flow Structure

With the advent of the knowledge-based economy, the inter-industrial flow of technological knowledge is reckoned as the principal determinant of national competitiveness. The mode of knowledge flows, however, is intractably complex. Taking it as a network, this paper aims at providing an inductive taxonomy of industries based on the knowledge flow structure and thus identifying the user-supplier relationship among industries in terms of knowledge diffusion. Some proxy indexes are developed first to measure the knowledge flows, then the interactive mechanism among industries is investigated by the network analysis and eventually a taxonomy of industries is presented according to the characteristics of respective industries. The taxonomic approach highlights the importance of inter-industrial knowledge management system that facilitates knowledge flows across industries based on the idiosyncratic features of respective industries.     

Adam Smith's theory of economic history and economic development

Abstract

The aim of the paper is to show that Smith has a theory of economic history grounded in a politico-economic modeling (as well as a sort of economic theoretical modeling). In terms of the politico-economic approach, in the Wealth of Nations (Book III.ii–iv) Smith tried to offer a systematic account of economic development from feudalism to capitalism in Europe. These lead to suggest that the seeming internal inconsistency between the natural and the actual courses of progress in Book III may be resolved, and that Smith may be treated as a precursor of Douglass North, who stressed an inextricable link between the polity and the economy in economic history.     

Standardization in electronic money

Abstract

Electronic money services are provided by the combination of Integrated Circuit (IC) cards and terminals. The compatibility of different brands of electronic money can be enabled by firms' joint adoption of standard terminals. In this paper, we analyse the effect of achieving compatibility among different brands of electronic money. We show that, if the unit production cost of a standard terminal is not so much different from that of a non-standard one, firms' joint adoption of standard terminals will increase the total sales of IC cards and the network size of terminals, thus raising consumers' surplus and firms' profits. On the other hand, if the unit cost of a standard terminal is so high that firms are discouraged from voluntarily adopting standard ones, the government may employ subsides to enhance efficiency. However, if the duty of implementing standardization is placed solely on the firms without subsidies, all the agents, including consumers and retailers, will be left worse off.     

A Pre-purchase Product Trial of a Monopolist with Multiple Products

For the heterogeneous consumers who do not know their individual utilities from a new product, a pre-purchase product trial would be helpful. We found out that a monopoly firm with two similar products would have a strong incentive not to allow a pre-purchase product trial, even though it is socially optimal to allow it. Furthermore, it is more likely for a monopoly firm with a pre-purchase product trial policy to introduce a new product to the market when introducing a new product is socially optimal.     

Nonlinear Mean Reversion across National Stock Markets: Evidence from Emerging Asian Markets

This paper seeks empirical evidence of nonlinear mean-reversion in relative national stock price indices for Emerging Asian countries. It is well known that conventional linear unit root tests suffer from low power against the stationary nonlinear alternative. Implementing the nonlinear unit root tests proposed by Kapetanios et al. (2003 Kapetanios, G., Shin, Y. and Snell, A. 2003. Testing for a unit root in the nonlinear STAR framework. Journal of Econometrics, 112: 359–379. [Crossref], [Web of Science ®] , [Google Scholar]) and Cerrato et al. (2009 Cerrato, M., de Peretti, C., Larsson, R. and Sarantis, N. 2009. “A nonlinear panel unit root test under cross section dependence”. Working Papers 28, Department of Economics, University of Glasgow [Google Scholar]) for the relative stock prices of Emerging Asian markets, we find strong evidence of nonlinear mean reversion, whereas linear tests fail to reject the unit root null for most cases. We also report some evidence that stock markets in China and Taiwan are highly localized.     

The Effects of Tariffs and Export Subsidies on Entry Barriers and Investment

This paper explains the effects of unilateral tariffs and export subsidies on entry decisions in an imperfectly competitive industry, and suggests that carefully targeted trade policies play a strategic role in shifting the industry structure and the terms of subsequent competition. The model provides a new justification for tariffs which is different from the traditional infant industry argument; the tariff affects foreign firms' reactions as well as those of the domestic firms.

The Permanent Export Hypothesis and Foreign Trade of a Centrally Planned Economy: A Case Study of North Korea

Huge outstanding debts of Third World Centrally Planned Economies(CPEs) notwithstanding, their trades with industrialized countries have been continuing briskly. In order to safeguard against an aggravation of current debts of the CPE, however, an industrialized country determines annually the maximum amount of imports permitted for a CPE on the basis of the CPE's permanent exports. This paper attempts to develop a permanent export model and apply it to the foreign trade of North Korea. [F 14]
