We examine the neglected area of internationalisation by VCs. Using a representative sample of 195 VCs, we show that the decision of a European VC firm to invest internationally is driven by its human resources. Having more VC executives in general and more VC executives with previous international experience in specific, results in a higher probability of investing internationally. In contrast, more VC executives with experience in the VC industry or with an engineering background lead to a higher probability of remaining domestic.  相似文献

Scanner data for fast moving consumer goods typically amount to panels of time series where both N and T are large. To reduce the number of parameters and to shrink parameters towards plausible and interpretable values, Hierarchical Bayes models turn out to be useful. Such models contain in the second level a stochastic model to describe the parameters in the first level.  相似文献

A social choice rule (SCR) is a collection of social choice correspondences, one for each agenda. An effectivity rule is a collection of effectivity functions, one for each agenda. We prove that every monotonic and superadditive effectivity rule is the effectivity rule of some SCR. A SCR is binary if it is rationalized by an acyclic binary relation. The foregoing result motivates our definition of a binary effectivity rule as the effectivity rule of some binary SCR. A binary SCR is regular if it satisfies unanimity, monotonicity, and independence of infeasible alternatives. A binary effectivity rule is regular if it is the effectivity rule of some regular binary SCR. We characterize completely the family of regular binary effectivity rules. Quite surprisingly, intrinsically defined von Neumann–Morgenstern solutions play an important role in this characterization.  相似文献

Measuring volatility with the realized range   总被引:1,自引:0,他引:1  
Realized variance, being the summation of squared intra-day returns, has quickly gained popularity as a measure of daily volatility. Following Parkinson [1980. The extreme value method for estimating the variance of the rate of return. Journal of Business 53, 61–65] we replace each squared intra-day return by the high–low range for that period to create a novel and more efficient estimator called the realized range. In addition, we suggest a bias-correction procedure to account for the effects of microstructure frictions based upon scaling the realized range with the average level of the daily range. Simulation experiments demonstrate that for plausible levels of non-trading and bid–ask bounce the realized range has a lower mean-squared error than the realized variance, including variants thereof that are robust to microstructure noise. Empirical analysis of the S&P500 index-futures and the S&P100 constituents confirms the potential of the realized range.  相似文献

In this paper, a conceptual framework for consumer reporting at the organizational level is developed. Consumer reporting is defined as the provision of information by an organization to its consumers with respect to the effects of its activities judged relevant by those consumers. In this context, the term organization covers business firms but also governmental agencies, hospitals, charities, and other non-profit organizations with relations to their consumers/clients.The concept of consumer satisfaction is regarded as the core element of consumer reporting. Several issues with respect to consumer satisfaction and dissatisfaction as well as their measurement are discussed. It is concluded that perceptual indicators of consumer satisfaction should constitute the core of consumer reporting in establishing the consumer profile of the organization. However, additional information could be provided too, for instance situational indicators of consumer satisfaction or information about consumer dissatisfaction. All of this information should be geared towards the goal of accounting for the resulting organizational strategy and policies towards the consumers. Several practical examples are given to illustrate the items about which information can be provided and the fact that consumer reporting can be realized in practice.
Berichterstattung von Organisationen für Verbraucher: ein konzeptioneller Rahmen
Zusammenfassung Eine solche Berichterstattung wird im vorliegenden Beitrag definiert als Informationen einer Organisation für ihre Konsumenten über diejenigen Wirkungen ihrer Aktivitäten, die von diesen Konsumenten für wichtig gehalten werden. Der Begriff Organisation steht hier nicht nur für kommerzielle Firmen, sondern auch für Behörden, Krankenhäuser, Stiftungen und andere nicht gewinnorientierte Organisationen mit ihren jeweiligen Beziehungen zu ihren Verbrauchern bzw. Klienten.Das Konzept der Verbraucherzufriedenheit steht dabei im Mittelpunkt. Deshalb werden zunächst dieses Konzept und die Methoden zur Messung von Verbraucherzufriedenheit diskutiert. Ergebnis ist dabei, daß das Konsumentenprofil einer Organisation durch perzipierte Indikatoren ermöglicht wird. Figur 1 gibt hierfür ein Beispiel. Das Konsumentenprofiel kann durch situative Indikatoren und durch Informationen über Verbraucherzufriedenheit ergänzt werden (Figur 2). Alle diese Informationen sollten zum Ziel haben, die Unternehmenspolitik gegenüber den Konsumenten zu verantworten.Zum Schluß werden einige praktische Beispiele behandelt, die einerseits zeigen, welche Informationen solche Berichterstattungen enthalten können, und andererseits, daß es in der Praxis bereits Ansätze in dieser Richtung gibt.

Rationing in open economy and dynamic macroeconomics: A survey   总被引:1,自引:1,他引:0  
Summary A survey of rationing in micro theories of macroeconomics is presented. The survey starts with a closed economy with money and inventories, which consists of a representative household, a firm and government. After a discussion of the notional demands and supplies and the properties of the Walrasian equilibrium, a discussion of the effective demands and supplies leads to an analysis of the four regimes (Keynesian unemployment, classical unemployment, repressed inflation and underconsumption). A fiscal and monetary contraction decreases sales and employment when there is Keynesian unemployment, but is expansionary (neutral) when there is repressed inflation (classical unemployment). The survey continues with an analysis of the effects of rationing in a small open economy. It considers the one-sector model and a model with a traded and a nontraded sector. The latter model is used to discuss the effects of an oil discovery on the Gulf countries and on Latin American countries. The survey ends with a discussion of rationing in dynamic economies, which leads to an analysis of the effects of expectations about future constraints on current regimes and to a discussion of boot-strap equilibria.The author is Director of the Network for Quantitative Economics. This paper is a brief and eclectic survey of rationing models of closed one-period and two-period economies and of small open economies. It contains no significant new material. The author is grateful to Professor Theo van de Klundert for his constructive comments on an earlier version of this survey.  相似文献

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.

The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment.  相似文献

Could external restraint and internal balance in Mexico havebeen reconciled at levels of savings and investment that allowedsatisfactory growth in output without the 1989–90 restructuringof debt? What are the likely implications of Mexico's "Bradydeal" on economic growth? What are the macroeconomic effectsof debt-equity swaps? This article develops and estimates amodel to address these issues. The analysis concludes that the1989–90 agreement in Mexico will contribute materiallyto macroeconomic stability and the restoration of economic growth.  相似文献

The Ju/'hoan Bushman Development Foundation (JBDF) is a multi‐dimensional development foundation which has as its main objective the raising of the standard of living of the indigenous Ju/'hoan Bushmen in eastern Bushmanland, Namibia. It has a basic needs approach to development.

The development activities of the Foundation started in 1981. The Nyae Nyae Farmers’ Cooperative, through which the Foundation now directs its development activities, was established in 1986. It is funded by various international development agencies, such as Christian Aid, NORAD, SIDA, Bread for the World, Oxfam Canada, and the EEC.

The basic needs approach of the Foundation addresses the following dimensions: water, food, cash, clothing, health, literacy and education, community esteem, and problems and propositions.  相似文献
