Policy makers have traditionally considered the macroeconomic relations and the variables that can affect the economic objectives that they pursue, such as prices, employment, balance of payments, and economic growth. Recently, microeconomic behavior has also been considered. To complete the analysis, it is necessary to include those variables that define the firm's evolution and activities, and cash flow could be this kind of variable to be included in the analysis. The main objective of this paper is to show the relationship between cash flow and one of the final economic policy targets, economic growth. This paper considers the relationship between cash flow and applied economics, then develops the effects of cash flow on economic growth.  相似文献

This paper analyzes differences in firms’ responsiveness to PROPER, Indonesia’s public disclosure program for industrial pollution control. The overall effectiveness of this program at achieving emissions reductions and its low regulatory costs have earned it a good reputation around the world. PROPER had no deterrents or incentives other than those that arose indirectly from publicly disclosing information about the environmental performances of firms. We analyzed plant-level data to relate short- and longer-term environmental responses to facility characteristics. The results revealed that foreign-owned firms were consistently more likely to respond to the environmental rating scheme, compared to private domestic firms. This is a clear and important insight with consequences for a number of issues, such as understanding the pollution haven debate. Also, firms located in densely populated regions, particularly in Java, responded more positively to the public disclosure of PROPER ratings. The main observed effect was however given by the initial level of environmental performance of firms. Those firms that had bad environmental performance records felt pressure to improve, but if the initial abatement steps had already been taken, the incentives to improve further appeared to diminish.  相似文献

We study minimum cost spanning tree problems with groups. We assume that agents are located in different villages, cities, etc. The groups are the agents of the same village. We introduce a rule for dividing the cost of connecting all agents to the source among the agents taking into account the group structure. We characterize this rule with several desirable properties. We prove that this rule coincides with the Owen value of the TU game associated with the irreducible matrix.  相似文献

Experimental and empirical evidence highlights the role of networks on social outcomes. This paper tests the properties of exogenously fixed networks in team production. Subjects make the same decisions in a team work environment under four different organizational networks: the line, the circle, the star, and the complete network. In all the networks, links make information available to neighbors. This design allows us to analyze decisions across networks and a variety of subject types in a standard linear team production game. Contribution levels differ significantly across networks and the star is the most efficient incomplete network. Moreover, our results suggest that subjects act as conditional cooperators with respect to the information received from the network.  相似文献

The European Treaty supports the application of the polluter pays principle in all environmental policies including the Water Framework Directive. This paper assesses the efficiency of water-charging systems in two European regions. The regions examined are the South west region of Ireland and the Navarre region in Spain which were selected because they are similar in terms of economic indicators but different in terms of water pricing structures. The paper describes the development and application of a simple model to analyse data on water-charging systems from these two regions. We present the results of a detailed scenario-based investigation illustrating the differences between experience, composition and basis, impact and constraints on the application of water charges for both regions. The key findings are that existing water charges do not provide incentives for users to use water efficiently and thereby do not contribute effectively to the environmental objectives of the Water Framework Directive.  相似文献

The aim of this paper is to provide some empirical evidence about black–white differentials in the distribution of income and wellbeing in three different countries: Brazil, the USA and South Africa. In all cases, people of African descent are in a variety of ways socially disadvantaged compared with the relatively more affluent whites. We investigate the extent of these gaps in comparative perspective, and analyze to what degree they are associated with differences in the observed characteristics of races, such as where they live, the types of household they have, or their performance in the labor market. We undertake this analysis with the Oaxaca–Blinder decomposition at the means and with a propensity score approach at the entire distribution. Our results show how the factors underlying the racial divide vary across countries and income quantiles.  相似文献

Open Source Software projects base their operation on a collaborative structure for knowledge exchange in the form of provision or reception of information, expertise and feedback on the creation of source code. Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects’ diffusion over the network.

We study the effects of police monitoring on crime. We exploit detailed information on the location and date of installation of police-monitored surveillance cameras, coupled with data at the street-segment level on all reported crimes in the city of Montevideo, Uruguay. We find that the introduction of police-monitored surveillance cameras reduces crime by about 20 percent in monitored areas relative to a pure control group located outside the city. We also explore potential displacement effects, and we do not find evidence of such effects.  相似文献

In the current global corporate climate that surrounds us, firms would do well to encourage the talent and creativity of their employees in order to achieve success. This is achieved, not by giving priority to individual talent, but by optimizing the collective as a whole and the firm’s activity based on team work and joint effort. Heads of organizations might benefit from creating a favorable context for the birth and growth of collective internal cooperation, which is understood to be the collective ability to create and innovate on the part of the team, the firm or the organization. Having contrasted our hypotheses through research on Spanish firms, we have concluded that job satisfaction and commitment to the team are factors that have a direct and positive effect on collective entrepreneurship.  相似文献

In this paper, we determine the density functions of nonsymmetrised doubly noncentral matrix variate beta type I and II distributions. The nonsymmetrised density functions of doubly noncentral and noncentral bimatrix variate generalised beta type I and II distributions are also obtained.  相似文献
