What kind of institutions are needed to stabilize and foster democracy? Clearly elections are crucial and much of the institutional and legal surrounding of elections has been subject to research. Two institutional variables have been neglected though, specifically in empirical research: Electoral Management Bodies (EMBs) and International Observer Missions (EOMs). Can EMBs and EOMs foster free and fair elections? If yes, under what conditions? And what kind of competences are needed for them? We hypothesize that both can become crucial institutions for free and fair elections. Whereas independent central banks or audit courts control special issue areas in order to take certain decision out of the realm of politics, EMBs control the moment of the set-up of government—the election, when conflicts of interest of politicians are at its peak. Although other kinds of independent administrative agencies have been the subject of political science and economic research, EMBs and EOMs have also been neglected here. This article undertakes to outline a conceptual framework for testing various hypotheses on the institutional set-up of EMBs. Hypothesizing that de iure and de facto independence of EMBs foster fair elections, the detailed institutional set-up of EMBs as independent variable is outlined in order to test for the level of democracy as a dependent variable. Furthermore, the importance of EOMs as well as their interaction effect with EMBs is analyzed. Although by now EOMs are sent to almost any country with elections, their impact has not been analyzed in an encompassing way in spite of that the mission have intensified in their work, have become more costly and their verdicts are gaining ever more publicity. 相似文献

Abstract. In this paper we study endogenous formation of communication networks in situations where the economic possibilities of groups of players can be described by a cooperative game. We concentrate on the influence that the existence of costs for establishing communication links has on the communication networks that are formed. The starting points in this paper are two game-theoretic models of the formation of communication links that were studied in the literature fairly recently, the extensive-form model by Aumann and Myerson (1988) and the strategic-form model that was studied by Dutta et al. (1998). We follow their analyses as closely as possible and use an extension of the Myerson value to determine the payoffs to the players in communication situations when forming links is not costless. We find that it is possible that as the costs of establishing links increase, more links are formed. 相似文献

The article analyzes optimal portfolio choice of utility maximizing agents in a general continuous-time financial market model under a joint budget and downside risk constraint. The risk constraint is given in terms of a class of convex risk measures. We do not impose any specific assumptions on the price processes of the underlying assets. We analyze under which circumstances the risk constraint is binding. We provide a closed-form solution to the optimization problem in a general semimartingale framework. For a complete market, the wealth maximization problem is equivalent to a dynamic portfolio optimization problem. 相似文献

This paper compares the forecast performance of automatic leading indicators (ALIs) and macroeconometric structural models (MESMs) commonly used by non-academic macroeconomists. Inflation and GDP growth form the forecast objects for comparison, using data from China, Indonesia and the Philippines. ALIs are found to outperform MESMs for one-period-ahead forecasts, but this superiority disappears as the forecast horizon increases. It is also found that ALIs involve greater uncertainty in choosing indicators, mixing data frequencies and utilizing unrestricted VARs. Two ways of reducing the uncertainty are explored: (i) give theory priority in choosing indicators, and include theory-based disequilibrium shocks in the indicator sets; and (ii) reduce the VARs by means of the general-to-specific modeling procedure. 相似文献

Offshoring service work is an accelerating trend. While the cost-savings from offshoring service work are usually clear, operating at a distance also brings with it certain “invisible costs.” We combine existing service operations theory with insights from the literature on communications and culture to present a new conceptual framework, organized around interaction intensity and interaction distance. We identify the drivers of these costs. We conclude with recommendations for controlling or attenuating invisible costs in offshoring service work. 相似文献

Forecasting inflation with an uncertain output gap 总被引:1,自引:0,他引:1
The output gap is a crucial concept in the monetary policy framework, indicating demand pressure that generates inflation.
However, its definition and estimation raise a number of theoretical and empirical questions. This paper evaluates a series
of univariate and multivariate methods for extracting the output gap in Norway, and compares their value added in predicting
inflation. We find that models including the output gap have better predictive power than models based on alternative indicators,
and they forecast significantly better than simple benchmark models. Furthermore multivariate measures of the output gap perform
better than the univariate gaps.

Livestock form key components of the livelihood strategies of many of the world's poorest people. However, despite the potential to alleviate poverty and improve food security through livestock development interventions, the lack of smallholders' participation in the planning and design of breeding programs has often been a major cause of the failure of such programs. Particularly in developing countries where livestock production is still mostly subsistence-oriented and livestock fulfil manifold functions a considerable number of livestock breeding programs have failed. The development of adequate tools to characterise these functions, bearing in mind that these are expressed only rarely in properly functioning markets, is therefore important.This paper seeks to advance the application of such methodologies to the smallholder pig sector in Vietnam. A choice experiment was applied across 140 households involved in pig breeding in order to assess farmers' preferences and the trade-offs for a list of adaptive and productive traits. These included growth, reproduction, disease resistance, feed requirements and appearance.The findings indicate that smallholders highly value both adaptive and performance traits, particularly in resource-driven (i.e. subsistence) production systems. Performance traits were more highly valued in the demand-driven (i.e. market-oriented) systems. These findings have implications for breeding program breed choice and breeding objectives. 相似文献

This article provides evidence that patent protection can have a positive effect on trade, by analysing the impact of the implementation of intellectual property rights (IPR) in developing countries on the US exports of pharmaceutical products, following intense lobbying efforts from the US pharmaceutical industry to have the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement included in the creation of the World Trade Organization (WTO). A gravity model using panel data from 1995 to 2010 suggests that the implementation of minimum standards of patent protection has increased US exports of pharmaceuticals to 108 nonadvanced countries. 相似文献

Abstract This paper uses dictator experiments to examine gender differences in altruistic behavior in the United States when decisions are made individually and jointly. In anonymous individual giving to charity, women give substantially more than men, and in paired settings, mixed-sex groups give the most while all male pairs give the least. Evidence supports social information and negotiation effects as participants change giving toward that of their partners. Social image effects are found only in mixed-sex groups, indicating a gender-based component to the value of the social signal sent. Although men and women appear to have similar influence, the positive social image effect pushes giving in mixed-sex pairs above the sum of the members' individual gifts because the less altruistic partners (usually men) adjust their giving upward more than the more altruistic partners (usually women) reduce giving. Therefore, increasing women's participation in traditionally male spheres of decision making may result in more altruistic economic behavior. 相似文献
