Design-Based Properties of Linear Calibrated Estimators of a Finite Population Total

We extend Godambe's famous nonexistence theorem to classes of linear calibrated estimators. We also propose a new method for comparing sampling strategies in the design‐based framework without recourse to simulation.     

Accounting Practices and the Market Valuation of Accounting Numbers: Evidence from Indonesia, Korea, Malaysia, the Philippines, Taiwan, and Thailand

This study examines the relation between stock prices and accounting earnings and book values in six Asian countries: Indonesia, South Korea, Malaysia, the Philippines, Taiwan, and Thailand. The analysis is based on a residual earnings model that expresses the value of the firm in terms of book value and residual income. The model holds for any clean surplus accounting system. However, for finite time horizons, biased accounting may affect model estimates. The six countries examined in this study differ in faithfulness to clean surplus accounting as well as bias (conservatism). The study addresses two questions. First, are there systematic differences across countries in the value relevance of accounting, and are these differences related to accounting differences? Second, are there systematic differences in the incremental and relative information content of book value per share (BVPS) and abnormal (residual) earnings per share (REPS) across the countries, and are such differences related to accounting differences? We find differences across the six countries in the explanatory power of BVPS and REPS for firm values. Explanatory power for Taiwan and Malaysia is relatively low while that for Korea and the Philippines is relatively high. These differences are generally consistent with differences in accounting practice; however, since Korean accounting practice is strongly influenced by tax law, we did not expect the high association for Korea. Second, with respect to the incremental and relative explanatory power of BVPS and REPS, we find BVPS to have high explanatory power in the Philippines and Korea but little in Taiwan. In all six countries REPS has less explanatory power than BVPS in most years. Again, the evidence may be interpreted as suggesting accounting practice affects valuation (with Korea again as the exception). Finally, we provide evidence on the sensitivity of the timing of comparisons of stock prices and accounting values. We find that comparing prices at year-end (even though annual accounting information has not been released at that time), in general, provides the highest correlation between market and accounting numbers.     

The effective use of marketing research consultants

Relatively little has been written about effectively managing the buyer-seller relationship for marketing research services. To provide insights into effectively managing this relationship, a survey of both buyers and sellers of marketing research services was conducted. Major findings were that proper problem definition, a familiarity with research methods by the research buyer, and continuous communication between buyer and seller were critical determinants of a successful consultant relationship. For best results the market research buyer-seller relationship should be treated as a mutually beneficial one, not one of conflict or acrimony.     

Cooling-Off Periods in the Consumer Laws of the EC Member States. A Comparative Law and Economics Approach

Lawyers tend to see cooling-off periods in consumer laws as a remedy for the problems caused by unequal bargaining power between sellers of goods and consumers. This article takes a different approach and argues that cooling-off periods can be seen as efficiency-enhancing devices. From an economic point of view, cooling-off periods provide a remedy for irrational behaviour on the part of consumers and may cure market failures, in particular problems caused by situational monopolies and asymmetric information. In spite of these important benefits, the economic approach also warns against possible disadvantages. The latter range from a moral hazard problem on the side of the consumer to the adverse counter-productive effects of cooling-off periods. A legislator who is informed by economic analysis may design cooling-off periods in ways that maximise their ability to cure inefficiencies and at the same time minimise their potential detrimental effects. Unfortunately, the relevant EC Directives and the current consumer laws of the Member States are not in perfect harmony with an efficiency enhancing-approach.

The causes of the economic crisis

The authors are attempting an objective elucidation of the economic crisis in Portugal. They are dealing with the influence of excess investment, with external economic factors such as the energy crisis and the recession in the industrial countries, and with the consequences of the revolutionary process.     

The determinants of medical malpractice incidents: Theory of contingency fees and empirical evidence

Summary A common criticism of the contingent fee arrangement is that it increases the total number of claims [Dietzet al., 1973, pp. 87–167]. This is true. But without contingent fees, risk averse plaintiffs would not offer the fair value of an incident and, as a consequence, would bear more of the cost of medical malpractice. This conclusion was reached in Section II by examining an expected utility model of plaintiff's decision-making.Section III presented empirical evidence on the determinants of malpractice incidentsper capita. High income, exposure to surgical operations, and a favorable legal system encourage incidents. The supply price of lawyers' time is negative and significant.This project was supported by Grant Number HS 01971 to the Health Services Research Center of the University of North Carolina at Chapel Hill from the National Center for Health Services Research, HRA.
