The East Asian crisis and financing corporate investment: is there a cause for concern?

In view of limited empirical evidence concerning the microeconomic aspects of corporate financial problems in the East Asian countries in the 1990s, this paper analyses the financing pattern of corporate investment in Indonesia, Korea, Malaysia, and Thailand. The analysis is based on an unbalanced panel of listed firms during the period 1989–1997. By using firm size, retention practices, and leverage as three different indicators of financial constraint on firm investment, we have examined the role of various internal and external financing variables on corporate investment in the sample countries. Results indicate that a large number of sample firms depend on free cash flow, especially in Indonesia; there was also a steady increase in debt-equity ratio in all countries. There were signs of agency costs in the use of cash flow in Korea and Malaysia and also in the use of debt financing in Malaysia and Thailand. There was also sign of over-investment among the Thai firms during 1994–1997 though it appears very little if at all was done to redress it in time.     

Contestability and two-part pricing

This paper contributes to the debate over the relevance of contestability by demonstrating that the welfare properties claimed by proponents depend on the inability of incumbent firms to divide the market. Given the ability to divide the market using two-part prices, the incumbent can protect profitability. This possibility further illustrates the extremity of the assumptions upon which contestability rests as two-part pricing is commonly observed in some of the very markets that might be suggested to be more nearly contestable.The authors thank Barnali Gupta, William G.

Consistent moment estimators of regression coefficients in the presence of errors in variables

This paper examines the possibilities of moment estimators of regression coefficients in the errors-in-variables problem suggested by Geary (1942) and others [Scott (1950) and Drion (1951)]. This approach yields consistent estimators of regression coefficients based on uni- and bi-variate moments (or cumulants) of third or higher order. These are computationally simple and need milder assumptions than the standard techniques, viz., ML and IV estimation. After a review of past investigations, this paper proposes new moment estimators and compares the asymptotic efficiencies of six estimators proposed earlier or here and of the OLS estimator. The case where the true regressor is lognormally distributed receives considerable attention in this communication.     

An EM algorithm for the destructive COM-Poisson regression cure rate model

In this paper, we consider a competitive scenario and assume the initial number of competing causes to undergo a destruction after an initial treatment. This brings in a more realistic and practical interpretation of the biological mechanism of the occurrence of tumor since what is recorded is only from the undamaged portion of the original number of competing causes. Instead of assuming any particular distribution for the competing cause, we assume the competing cause to follow a Conway–Maxwell Poisson distribution which brings in flexibility as it can handle both over-dispersion and under-dispersion that we usually encounter in count data. Under this setup and assuming a Weibull distribution to model the time-to-event, we develop the expectation maximization algorithm for such a flexible destructive cure rate model. An extensive simulation study is carried out to demonstrate the performance of the proposed estimation method. Finally, a melanoma data is analyzed for illustrative purpose.     

成功应用CRM的三大法宝

现实中,人们常常会因为对现有系统的不满而考虑采用一个CRM系统,但根据一份从2000年以来的客户调查结果显示,超过80%的CRM系统最初都没有经过周密的组织部署,只有少数行业如零售、医药和航空例外。许多公司由于缺乏资金、组织或兴趣,不得不采用渐进式地,自下而上的“游击式”CRM系统（gCRM）。在未来的三年内,成功的CRM战略将克服组织、渠道、价值、产品和技术的障碍,成为极具价值的客户管理系统。但是,这将依赖于IT经理是否对将要进行的CRM项目做战略计划。这里将介绍几种方法来推动CRM项目——虽然目前还没有完美的方…     

How Much of the Gender Difference in Child School Enrolment Can Be Explained? Evidence from Rural India

There are significant gender differences in child schooling in the Indian states though very few studies explain this gender difference. Unlike most existing studies we take account of the implicit and explicit opportunity costs of schooling and use a bivariate probit model to jointly determine a child's participation in school and market jobs. Results obtained from the World Institute of Development Economics Research (WIDER) villages in West Bengal suggest that indicators of household resources, parental preferences, returns to and opportunity costs of domestic work significantly affect child school enrolment. While household resources have similar effects on enrolment of boys and girls, other arguments tend to explain a part of the observed gender difference. Even after taking account of all possible arguments, there remains a large variation in gender differences in child schooling that cannot be explained by differences in male and female characteristics in our sample.     

COOPERATIVE MANAGERIAL DELEGATION,R&D AND COLLUSION

Existing literature on managerial delegation indicates that collusive outcomes can be obtained in an oligopoly game through cooperative managerial delegation. In contrast, this paper shows that, if managers are delegated to choose R&D, in addition to choosing production levels, full‐collusive outcomes cannot be achieved through cooperative delegation. Moreover, (i) under cooperative delegation, semi‐collusion always yields lower profit, higher R&D, higher price and lower social welfare than that in the case of competition and (ii) cooperative delegation leads to a higher profit lower R&D, higher price and lower social welfare than the no delegation case, irrespective of product market conduct.
