Third world strategies for regulating drug advertising and marketing

In the pharmaceutical area, third world countries have been particularly subjected to excessive pricing and manipulative marketing practices by multinational corporations. Sri Lanka has gained some experience in curbing abuses by establishing a State Pharmaceuticals Corporation. It has been able to achieve substantial price cuts for pharmaceuticals and to adapt to changing economic and political circumstances. The control of advertising and marketing practices remains a problem but has been tackled in Sri Lanka by an Act of 1980. Until similar laws are enacted greater attention should be given to the individual patient by doctors becoming more circumspect in prescribing drugs.

Strategien der Länder der Dritten Welt zur Regulierung des Vertriebs und der Werbung von Arzneimitteln

Zusammenfassung Länder der Dritten Welt sind für multinationale Unternehmen auf dem Arzneimittelsektor ein bevorzugtes Objekt für Ausbeutung durch überhöhte Preise oder manipulatives Marketing. Der Autor, mit diesen Problemen an leitender Stelle persönlich vertraut, beschreibt Versuche in Sri Lanka, Mißbräuche ausländischer Unternehmen durch Errichtung einer staatlichen pharmazeutischen Gesellschaft (State Pharmaceuticals Corporation) zu bekämpfen.Das Unternehmen hat wesentliche Preisreduzierungen für Arzneimittel erreicht und sich an geänderte wirtschaftliche und politische Verhältnisse anpassen können. Werbung und Vertriebsmethoden werden neuerdings in Sri Lanka — wie in anderen Ländern der Dritten Welt — durch ein Gesetz von 1980 kontrolliert, das allerdings für homöopathische und ähnliche Produkte nicht gilt. In der Zukunft kommt es darauf an, den individuellen Patienten durch eine vorsichtigere Verschreibung von Arzneimitteln mehr Aufmerksamkeit zu widmen.

SOME RECENT RESEARCH INTO HOME HEATING

As part of an investigation into the performance of heating systems and the effectiveness of energy saving measures, temperatures have been monitored in forty centrally heated homes. The addition of extra insulation had no effect on the way people operated their heating system or on the temperature level set in the main living room. However, bedrooms were warmer and the importance of individual room temperature controls demonstrated. Differences between people's thermal requirements in domestic and office environments are considered.     

RESPONSES TO RISK IN WEED CONTROL DECISIONS UNDER EXPECTED PROFIT MAXIMISATION

Risk is an important characteristic of decisions about weed control in crops. In this paper it is shown that risk can affect weed control decisions even if the objective of the decision maker is to maximise expected profits: that is, even if the decision maker is ‘risk-neutral’ in the usual economic sense. This is shown for two decision frameworks: the optimal rate approach and the economic threshold approach. Empirical results are presented for control of ryegrass in wheat in Western Australia. It is found that, in general, risk reduces the optimal level of herbicide use under expected profit maximisation. Although individual sources of risk have a small impact on the optimal decision rules, combinations of uncertain variables can have a relatively large effect.     

AGRICULTURAL RESEARCH EXPENDITURES AND AGRICULTURAL PRODUCTIVITY CHANGE

This note comments on the econometric analysis of the dynamic relationship between agricultural research expenditures and agricultural productivity change. The validity of the Almon restrictions, particularly endpoint restrictions, commonly imposed on the distributed lag is questioned. It is suggested that models incorporating such restrictions may lead to biased estimates of the effects of research spending. More fundamentally, doubts are raised as to whether any meaningful relationship between research spending and productivity change can be established from the available data.     

Modern Trends and Problems of Migration in a Russian Border Region: The Far East

The article has analyzed trends and problems in migration processes in the Far East of Russia in the 2010s. There are restrictions on population growth in the Far East due to migration. It has been determined that the implementation of modern policy decisions with regard to the Far East region does not create real prerequisites for increasing the incomes of the population. It has been proved that, in order to attract population to the Far East, it is necessary to institute economic development in the region that can increase incomes and make them comparable to other more successful federal districts.     

Stock market efficiency the evidence from FTA indices of eleven major stock markets

Summary This article presents a survey of recent literature on stock market efficiency, with special reference to the US and Dutch stock markets. Additionally, models are specified and estimated for the daily return since 1987 on FTA indices for eleven major stock markets, allowing for non-normality, heteroskedasticity, leverage effects and autocorrelation. The leverage effect and positive autocorrelation are characteristics of some of the indices investigated. The magnitude of the autocorrelation, however, is so small, that no profitable arbitrage opportunities arise and weak-form efficiency of these stock markets is not rejected.     

Structural changes in U.S. agriculture: Implications for African American farmers

Structural changes in U.S. agriculture, influenced by technological and institutional forces, have altered the economic and social characteristics of rural America, especially that segment of rural America populated by farmers and their families. Changes in the structure of agriculture have greater implications for small scale farmers, many of whom are African American, in that strategic options for their farm-firms are constrained to: increasing their farm size, exiting farming, and obtaining off-farm employment to survive. This article presents a rationale for public support of limited resource farmers, identifies structural trends in U.S. agriculture and their impacts on African American farmers, discusses economic problems unique to these farmers, and recommends needs for specific public policies and development programs.     

Savings,pension rights and taxation

Summary The voluntary saving rate has declined in The Netherlands over the last thirty years. In this paper the increasing share of transfer income in total income, with a high propensity to consume, and the increase in collective pension schemes are simultaneously used to explain this development. Furthermore, the influence of taxes is modelled. The planning horizon of the representative consumer is treated as a parameter to be estimated. The planning horizon obtained (about 4.5 years) appears to be short compared to expected residual lifetime, implying rather small interest elasticities. The estimation results indicate that, in case the obligatory pension schemes are diminished, the representative consumer offsets the loss in pension benefits for 75 per cent by voluntary, additional accumulation of nonhuman wealth in the long run. The working of the model is illustrated by simulation experiments.I wish to thank two anonymous referees, Prof. J. Pen, G.M.M. Gelauff, J.J. Graafland, W. Vossers and other colleagues of the CPB for their helpful comments.
