A new bivariate distribution in natural exponential family

We propose a new bivariate distribution following a GLM form i.e., natural exponential family given the constantly correlated covariance matrix. The proposed distribution can represent an independent bivariate gamma distribution as a special case. In order to derive the distribution we utilize an integrating factor method to satisfy the integrability condition of the quasi-score function. The derived distribution becomes a mixture of discrete and absolute continuous distributions. The proposal of our new bivariate distribution will make it possible to develop some bivariate generalized linear models. Further the discrete correlated bivariate distribution will also arise from an independent bivariate Poisson mass function by compounding our proposed distribution (Iwasaki and Tsubaki, 2002).Received March 2003     

REPORTING GUIDELINES FOR META-ANALYSIS IN ECONOMICS

Meta-analysis has become the conventional approach to synthesizing the results of empirical economics research. To further improve the transparency and replicability of the reported results and to raise the quality of meta-analyses, the Meta-Analysis of Economics Research Network has updated the reporting guidelines that were published by this Journal in 2013. Future meta-analyses in economics will be expected to follow these updated guidelines or give valid reasons why a meta-analysis should deviate from them.     

The Advertising–price Relationship: Theory and Evidence

The relationship between advertising and price is important because the welfare effect of advertising depends upon the price effect of advertising. We attempt to provide a better understanding of the theoretical relationship between advertising and price. We establish theoretical conditions sufficient for advertising to raise prices. This will occur, for example, when firms play a supermodular game – a structure that considers the type of advertising (i.e., persuasive, image creating, or informative) and the effect that advertising has on a firm’s demand and costs. We also compare results from two simple duopoly models, one with horizontal and the other with vertical differentiation, and find that only the model with horizontal differentiation is supermodular for the forms of advertising that are thought to raise price (e.g., persuasive advertising). In consideration of these theoretical issues, we then develop an empirical model to determine whether advertising raises prices in the US brewing and cigarette industries.     

The determinants of corruption in transition economies

This paper examines the determinants of corruption in transition economies. We found that the progress of structural reform, comprising marketization, rule of law, and democratization had a crucial impact on the extent of corruption control in former socialist countries.     

The determinants of board composition in a transforming economy: Evidence from Russia

Using a unique dataset of 730 joint-stock companies, we studied the determinants of corporate board composition in Russia. Despite the widespread image of insider control in the 1990s, a large number of Russian companies now actively appoint outsider directors to monitor top management. The findings reported in this paper strongly suggest that the theories and empirical methods of financial and organizational economics help to pinpoint the factors affecting the extent of outsider directorship. We also found that, among potential determinants, bargaining variables have considerable explanatory power. Furthermore, our empirical evidence demonstrated that Russia's legal system and its peculiarities as a transition economy also exert a certain degree of influence on board composition.     

The effect of marketing regulations on efficiency: LeChatelier versus coordination effects

Government regulations designed to promote social welfare can have unintended consequences on efficiency. According to the LeChatelier Principle, regulations that effectively limit substitution possibilities among inputs will reduce firm and industry-wide efficiency. In imperfectly competitive markets, however, government constraints on a strategic variable can facilitate coordination. An advertising restriction, for example, would improve efficiency if it enables firms to produce the same level of sales with less advertising spending. We use data envelopment analysis to estimate the effect of marketing regulations on efficiency in the U.S. cigarette industry. Unlike previous studies, we do not assume that marketing and production technologies are separable. Our results demonstrate that coordination effects dominate LeChatelier effects. Cigarette producers have benefited from advertising restrictions, a result consistent with the capture theory of regulation.

The relationships between stress,health, and physically active leisure as a function of life‐cycle

This article examines relationships between stress, health, and participation in physically active leisure using data collected as part of the 1985 and 1990 U.S. National Health Interview Surveys (NHIS). In particular, the article analyzes: (a) the effects of life‐cycle progression (controlled for gender) on subjectively perceived stress and self‐reported health; (b) the role of physically active leisure in enhancing health or buffering adverse health outcomes of stress; and (c) the effects of selected social‐economic factors, such as education and income, on the relationships between life‐cycle, stress, health, and physically active leisure. According to our analyses: (1) stress is unevenly distributed across the life span; (2) stress‐reducing effects of physically active leisure are present among retired older people more so than in the middle‐aged life‐cycle groups; and (3) direct health‐enhancing effects of participation in physically active leisure are more evident than the buffering effects of leisure on stress‐health relationships. A critical discussion of methodological and substantive issues facing researchers interested in the relationships between leisure, stress, and health is provided.     

The governance mechanism of Russian firms: its self-enforcing nature and limitations

The legal form of business enterprises in contemporary Russia is diversified to almost the same extent as those in major advanced countries. Joint-stock companies are now the most common form of incorporation among leading industrial enterprises. The law on joint-stock companies in Russia provides for the governance mechanism of joint-stock companies, in order to implement the concept of a ‘self-enforcing’ organisation in which the legal code of business management should be observed voluntarily by managers and large stockholders. This fundamental idea is embodied in many aspects of the current system, including the mechanism of management and supervision characterised as ‘diarchial leadership’, the balance of power between stockholders and corporate officers, and the internal audit system. However, the self-enforcing nature of the Russian enterprise has been undermined by a number of factors, including the overwhelming expansion of closed joint-stock companies, the predominance of insider ownership, the short history of internal auditing and the lack of legal enforcement power. As a result, breaches of company law are rampant in Russia today. This raises serious problems for the Russian corporate system, along with the legal peculiarity of privatised firms and people's enterprises, which complicates the system of joint-stock companies and deprives it of transparency.     

The State Budget Compilation Process in Russia: Institutional Framework and Practice

This article clarifies the institutional framework and practice of the state budget compilation process in Russia, taking the 2001 federal budget as an example. The budget was the first one compiled under the new national financial system, including the Budget Code of the Russian Federation, which came into force in January 2000. The Budget Code is greatly superior to the preceding one, in the socialist era, which regulated Russia's financial activities during the initial phase of the transition period. Under the new legal system the 2001 budget was drafted by the Ministry of Finance, approved by the government, submitted to the Federal Assembly, discussed at the State Duma and finally approved by the Federation Council. A detailed analysis of this process shows that a certain order is emerging in the budget compilation process due to the comparatively amicable relationship between the government and the Federal Assembly and because of the establishment of the new legal system, including the Budget Code. The new financial system, however, has many problems, indicating that Russia will not be able to accomplish institutional changes in this field all at once.
