Issues in the estimation and application of latent structure models of choice

Our paper provides a brief review and summary of issues and advances in the use of latent structure and other finite mixture models in the analysis of choice data. Focus is directed to three primary areas: (1) estimation and computational issues, (2) specification and interpretation issues, and (3) future research issues. We comment on what latent structure models have promised, what has been, to date, delivered, and what we should look forward to in the future.     

CREATING VALUE WITH MERGERS AND ACQUISITIONS

This report addresses two key questions for today's top executives: Do acquisitions create value for acquirers? And under what circumstances have acquisitions created the most value for acquiring shareholders?
The authors' analysis of over 1,500 completed deals by non-financial companies in the United States over the past 12 years shows that, at announcement, acquirers' shareholders suffer small losses, on average, in the short term around the initial deal announcement. Over longer intervals, such as one or two years following the announcement of the transaction, acquirers tend to slightly outperform industry peers.
The average or median market response hides tremendous variability in how the market has reacted to individual deals, however. This article provides evidence that the "right" M&A transaction can create substantial value for acquirers. One-quarter of the transactions lead to market-adjusted gains in excess of 5% for the acquirer and oneeighth of the transactions lead to gains in excess of 10% in the short term. However, some deals have also destroyed substantial shareholder value.
Financing structure is a key driver of the stock market reaction. Stock-financed transactions, on average, have a negative stock market reaction, while cash-financed transactions have benefited acquirers in both the short term as well as the long term.
Acquisitions of private companies or assets and units of public companies have consistently generated higher returns for acquirers than purchases of public companies.
Moreover, EPS dilution is not a major driver of how the stock market reacts to a deal. Although "accretive" deals perform slightly better than "dilutive" ones in the short and long run, the difference is small and not statistically significant. Over the long run, acquiring shareholders have benefited the most from deals within the same industry and that avoid targets with relatively optimistic earnings growth projections.

The quality and effectiveness of marketing strategy: Effects of functional and dysfunctional conflict in intraorganizational relationships

By examining only dysfunctional conflict and ignoring functional conflict, empirical research in marketing has presented only part of the story. This research offers the first systematic look at the antecedents and consequences of both functionaland dysfunctional conflict in intraorganiational relationships. The authors develop and empirically test a causal model for key organizational antecedents of new product strategy quality and market performance. They find that dysfunctional conflict in the decision-making process has deleterious consequences for quality of strategy and market performance, whereas functional conflict improves both quality of strategy and performance. Specifically, organizational design characteristics such as formalization, interdepartmental interconnectedness, low communication barriers, and team spirit improve new product performance by enhancing functional conflict, whereas centralization and high communication barriers lower new product performance by increasing dysfunctional conflict. A post hoc test for common method bias or variance suggests that bias or variance alone cannot explain these findings.

Willingness to Pay to Reduce Mortality Risks: Evidence from a Three-Country Contingent Valuation Study

Valuing a change in the risk of death is a key input into the calculation of the benefits of environmental policies that save lives. Typically such risks are monetized using the Value of a Statistical Life (VSL). Since the majority of the lives saved by environmental policies are those of older persons, there has been much recent debate about whether the VSL should be lower for the elderly to reflect their fewer remaining life years. We conducted a contingent valuation survey in the UK, Italy and France designed to answer this question. The survey was administered in these three countries following a standardized protocol. Our results suggest that the VSL is €1.022 million or €2.264 million, depending on whether we use median or mean WTP. The VSL is not significantly lower for older persons, but is higher for persons who have been admitted to a hospital or emergency room for cardiovascular and respiratory problems. Income is positively and significantly associated with WTP. The income elasticities of the WTP increase gradually with income levels and are between 0.15 and 0.5 for current income levels in EU countries. We use the responses to the WTP questions to estimate the value of an extension in remaining life expectancy. The value of a loss of one year’s life expectancy is €54,000 or €163,000.     

Industrial relations law,employment security and collective bargaining in India: myths,realities and hopes

This article examines the debate on reforms in industrial relations law in India, needed to support its economic liberalisation programme. Analysing a distinctively Indian experience of state intervention in industrial relations, it concludes that the thrust of the reform should be towards entrusting union recognition and promotion of dispute settlement to an authority that is independent of the state executive.     

Sub additive measures of relative information and inaccuracy

Summary In the study of information theoretic measures, additivity has been the basic requirement. However it is quite interesting to investigate the sub-additive measures. Starting from subadditivity for measures associated with a pair of distributions of a discrete random variable, it has been changed into an equality relation using another function of a pair of distributions., Under the sum property of the function and the measures, the relation is expressed in terms of a functional equation of which the most general complex solutions have been obtained. In terms of the real continuous solutions of the functional equation, the sub-additive measures of Relative information and Inaccuracy have been defined and characterized. Particular cases and simple properties particularly the convexities of some of these new measures have also been studied.     

Relationship between generalizedh-Statistics and polykays

Summary In this paper, relationships between generalizedh-statistics which estimate powers and products of central moments unbiasedly and the polykays by using ordered partitions are established. A table expressing generalizedh-statistics of weight 12 in terms of polykays and vice versa is presented. Expressions of weight less than 12 are obtained from this table.

The effectiveness of government spending on education and health care in developing and transition economies

Recent studies show that corruption is associated with higher military spending [Eur. J. Polit. Econ. 17 (2001) 794] and lower government spending on education and health care [J. Publ. Econ. 69 (1998) 263]. This suggests that policies aimed at reducing corruption may lead to changes in the composition of government outlays toward more productive spending. However, little empirical evidence has been presented to support the claim that public spending improves education and health indicators in developing and transition countries. This paper uses cross-sectional data for 50 such countries to show that increased public expenditure on education and health care is associated with improvements in both access to and attainment in schools, and reduces mortality rates for infants and children. The education regressions are robust to different specifications, but the relationship between health care spending and mortality rates is weaker.
