The article reports from a study of 835 Berlin citizens, in which their needs for legal counselling in five walks of life were ascertained. Subjectively experienced problems were related by the respondents, both spontaneously and as answers to a standardized questionnaire; in the same manner, the investigators tried to find out in which way, if any, the respondents had tried to solve the problems. In this paper, only some results from the questions dealing withconsumer problems are reported. Among the results of the study can be mentioned: -Many more problems are reported for consumer durables than for insurance, holiday travel, and consumer credit (although when a problem arises in the latter spheres, they give rise to much concern). Doctors and consumer services (in particular, car repairs) show rather high problem rates, too; -Most problems have to do with perceived deficits of the delivered goods and services (rather than with the activities of the seller); -About 26% of the respondents explicitly stated that they had undertaken nothing by way of remedying the problem. The tendency to do nothing about it is clearly related to income (low income = proneness to do nothing). The relationship with education is less clear-cut. -In particular, those persons who had resorted to legal counselling as a means of solving their problem, were very satisfied with this, and planned to use the method again if need arose. Contacts with the seller were less favourably evaluated as a problem-solving means. Also those who had not undertaken any action in order to solve their problem, state to a surprisingly high degree that they plan to use legal advice (lawyers, consumer advice centres, courts) the next time a problem arises. Plans to use legal counselling are mentioned by many more than have used them in an actual conflict, and these intentions do not differ dramatically among different social classes. -Very few respondents (3%) report the use ofcollective action in attempts to solve their problem, but considerably more (15%) indicate a desire to solve future problems together with other consumers who find themselves in an similar situation. On the basis of the results of the study and theoretical considerations, the authors draw the following conclusions:
- A public consumer policy which entails the goals of consumer co-determination and self-reliance is more likely to succeed if it relates to deficiencies of goods and services perceived by the consumers. Consumer counselling should therefore change its focus from giving advice prior to decisions to giving advice about how to solve post-purchase problems.
- Because of consumer expectations, consumer guidance must include legal counselling. It should not be limited to such counselling, however, since most consumer problem alleviation takes place outside the legal system.
- Legal counselling should primarily aim at strengthening the position of the consumer innon-legal problem-solving attempts. Knowledge about the legal position is important because it gives self-confidence and increases the perceived rightfulness of one's concern. It creates the awareness that the problem is not an individual and rare one, and may give impetus to collective action. It makes it possible to see how one's problem is connected to other, related problem types. It strengthens the consumer's feeling of possessing negotiation power, since he can threaten with legal action, in case the seller does not yield, and it makes it possible for the consumer to specify minimum requirements in his dealings with the seller.
- Legal counselling that has as its only purpose the securing of consumer rights throughlegal procedures, puts the consumer under tutelage and runs the risk of becoming an instrument which isolates consumers from each other and make them incapable of solidarity with fellow citizens.
- Consumer counselling should as its starting-point take the problem-solving procedures usually employed by consumers (direct contacts with the seller, seeking advice from friends and colleagues) and attempt to make these procedures more efficient. The declared preparedness of consumers to consider collective actions should be put to use.
- Consumer counselling should not address itself to specific, “weak” consumer groups (old people, low-income groups, non-employed women) but should in the first place concentrate its attention on those kinds ofproblem situations (certain types of goods and services, certain types of confrontations with sellers, etc.) in which such especially vulnerable consumers find themselves.

The paper considers environmental regulation of a consumption good and an externality which influence demand and costs in a nonseparable way. Under monopoly two instruments are always required for first-best. The Pigouvian tax is more complicated than anticipated. 相似文献

Multiplier methods are used to round probabilities on finitely many categories to rational proportions. Focusing on the classical methods of Adams and Jefferson, we investigate goodness-of-fit criteria for this rounding process. Assuming that the given probabilities are uniformly distributed, we derive the limiting laws of the criteria, first when the rounding accuracy increases, and then when the number of categories grows large. 相似文献

This paper empirically analyzes the impact of exchange-rate uncertainty, exchange-rate movements, and expectations on foreign
direct investment (FDI). Using data on US outward FDI for the period 1984–2004 we examine two competing measures of exchange-rate
volatility. While the standard measure yields a discouraging effect on FDI outflows in all industries the alternative risk
specification reveals a clear distinction between manufacturing and non-manufacturing industries, with the latter showing
a positive correlation with increased exchange risk. A real appreciation of host-country currency was associated with higher
FDI flows, while expectations about an appreciation showed a negative result. 相似文献

The German Federal Government wants to establish Germany as a leading market for electric mobility. Potential environmental benefits and changes in the economic framework conditions of the energy sector are described in this paper. In order to quantify the electricity split which is actually used for charging electric vehicles, two economic models for the energy sector, a model for the market penetration of electric vehicles, a vehicle model and an LCA model are brought together. Based on an assumed dynamic increase of electric vehicles to 12 million in 2030, an additional electricity demand of about 18 TWh is calculated. If the vehicles are charged directly after their last daily trip, the peak load increases by 12%—despite the small increase in electricity demand. First model calculations for the development of the European power generation system show that the direct impact on the construction of new power plants remains low even until 2030. An impact of electric mobility on CO2 certificate prices can only be seen from 2025 onwards and is limited to an increase in certificate prices by a maximum of 8 % in 2030. An optimisation is possible with intelligent charging strategies: The peak load without demand side management can be reduced by 5 GW and about 600 GWh of additional wind energy can used which would otherwise have been throttled due to feed-in management—about 3.5 % of the total electricity demand of electric vehicles. On the other hand, demand side management leads to more coal power plants instead of gas power plants being used to meet the additional electricity demand. If additional renewable sources are installed along with demand side management, the electricity for electric vehicles is almost carbon free. This is also reflected in the life cycle balance of electric vehicles which also includes vehicle and battery production: With today’s average electricity split in Germany, the greenhouse gas emissions of electric vehicles are about comparable to vehicles with conventional combustion engines. However, the electricity split in 2030 or the use of additional renewable energy sources lead to a significant advantage in the greenhouse gas balance. 相似文献

We bring in hierarchical education and skill formation within a standard Jonesian specific-factor model of production and trade for a developing economy. There are three types of labor, unskilled, medium skilled and high-skilled. The unskilled can only develop into medium-skilled and medium-skilled into high-skilled. As capital becomes internationally mobile, educational capital gets concentrated in particular types of education. In the process the society gets polarized between the highly educated and the absolutely uneducated. 相似文献

Abstract. In this paper the welfare effects of tariffs and import quotas in the presence of involuntary unemployment are derived and compared. The framework used is the standard model of a competitive small open economy with many goods and factors. Optimum levels of the respective trade policy instruments are derived, as well as welfare increasing reform strategies. In all cases, the labour intensity of the import‐competing sectors turns out to be a crucial variable for deriving the welfare effects. JEL classification: F13, F16 相似文献

The paper considers the evaluation of a nonmarket good on the basis of a complete conditional demand system. It introduces two conditions allowing to identify a generally unique underlying preference ordering which can be employed for evaluation. The functional structure of the corresponding expenditure/indirect utility function and the demand system is described. The conditions proposed turn out to be equivalent to the property of base level independence in the equivalence scale literature. The approach is operational. 相似文献
