In this paper, we investigate the relationship between economic development, investments, savings, insecurity and social conditions in Colombian departments. Using a dynamic heterogeneous panel analysis, we study the effects of insecurity and social conditions on economic development through an estimation of panel data cointegration techniques. The models applied in this study suggest a long-term relationship among economic development, investments, savings, social conditions and insecurity. Investments, savings and human development index have a positive and significant coefficient, which indicates that these variables produce incentives for economic development, whereas GINI and homicides have a negative relationship, demonstrating that these variables undermine economic development. All findings are important in the design of strategies and policies that strengthen income distribution equality, a key factor that determines growth and development through adequate government expenditures that encourage savings and investment decisions with the aim to improve welfare and the standard of living. 相似文献

The analysis of diffusion processes in financial models is crucially dependent on the form of the drift and diffusion coefficient functions. A new model for a stock market index process is proposed in which the index is decomposed into an average growth process and an ergodic diffusion. The ergodic diffusion part of the model is not directly observable. A methodology is developed for estimating and testing the coefficient functions of this unobserved diffusion process. The estimation is based on the observations of the index process and uses semiparametric and non-parametric techniques. The testing is performed via the wild bootstrap resampling technique. The method is illustrated on S&P 500 index data. 相似文献

This paper reviews three strands of the innovation literature that have presented innovation as a distributed process that combines knowledge of designers and users: user innovations, Science and Technology Studies (STS), and domestication research. These literatures have explored different aspects of the micro-processes through which use and design knowledge are locally embedded. This paper pulls together insights from the literatures, and identifies an important gap: the connections between the local embedding of use and design knowledge, and the meso dynamics of industrial and technological change. The paper then develops a number of integrating concepts and propositions for a framework to study the co-evolution of use and design in innovation processes. It also demonstrates that this framework is most valuable in researching how societal challenges become articulated over time in processes of technological change and innovation. 相似文献

Market Coupling and the CWE Project 总被引:1,自引:0,他引:1
The article copes with the ongoing effort to establish implicit auctions to allocate transmission capacity on cross-border interconnectors in the power grid. By the means of implicit auctions (in contrast to explicit auctions), cross-border capacities are included in the clearing of local power exchanges. Concerning the day ahead auction, ‘market coupling’ plays an important role. Market coupling connects (formerly often national) electricity markets, simplifying cross-border trade. One of the main drivers of market coupling projects is the pursuit of European market integration i.e. allowing for convenient cross-border trade. The other reason is the perception that explicit auctions of transmission capacity (in addition to energy auctions which are often performed later) do sometimes lead to sub-optimal results. The objective function of market coupling is the maximisation of total welfare of all connected markets. Further to the explanation of different market coupling models (also regarding capacity calculation), the current development in Europe is wrapped up—including the CWE market coupling (Central Western Europe) project. The CWE market coupling is announced to start in fall 2010, coupling the day-ahead electricity markets of Belgium, France, Germany, Luxembourg and the Netherlands. 相似文献

In this paper, we study how risk-shifting incentives and the design of debt covenants are affected by the pattern of temporal resolution of uncertainty (TRU) in the underlying technology of the firm. We show that the extent of risk-shifting as well as the yield demanded on corporate debt are larger the later the resolution of uncertainty (thus providing one explanation for the empirical evidence of Reisz and Perlich (2006)). We allow for contracting based on verifiable information disclosed by the manager. In this context, we characterize optimal covenants restricting investment. The effects of these covenants on the firm's investment policy and corporate bond yields under different disclosure policies and patterns of TRU are studied. Empirical implications are derived and discussed. 相似文献

The paper analyses and compares the role that the tightening in liquidity conditions and the collapse in risk appetite played for the global transmission of the financial crisis. Dealing with identification and the large dimensionality of the empirical exercise with a Global VAR approach, the findings highlight the diversity of the transmission process. While liquidity shocks have had a more severe impact on advanced economies, it was mainly the decline in risk appetite that affected emerging market economies. The tightening of financial conditions was a key transmission channel for advanced economies, whereas for emerging markets it was mainly the real side of the economy that suffered. Moreover, there are some striking differences also within types of economies, with Europe being more adversely affected by the fall in risk appetite than other advanced economies. 相似文献

Regional networking can help companies to gain competitive advantage, provided that the network is actively coordinated and managed. For this purpose, cluster initiatives aiming at delivering potentials for success for their members arouse in many regions in previous years. Based on literature, this article analyzes the different stages of development of a cluster initiative and the specific tasks of the cluster management in these stages. Applying the relational and the resource-based view, we explain possible company’s competitive advantages resulting from cooperation. Subsequently, we distinguish each stage and describe the specific tasks of the different protagonists of a cluster. Finally, we discuss these theoretic findings of how to develop cluster initiatives and their applicability by a case study of the HESSENMETALL Cluster Initiative and derive implications for science and management. 相似文献

We study how the sequence of financing of R&D varies according to the ease with which property rights over knowledge can be defined. There are two financiers: a venture capitalist (VC) and a corporation. The knowledge acquired in costly research becomes embodied in the researcher's human capital, and she may hold up the financier and walk away with the project to develop it elsewhere. The main results are: (1) When property rights are strong, research is always funded by the VC, development is performed efficiently, and breakaways from the VC to the corporation are observed in equilibrium. (2) When property rights are weak, projects may be financed by the VC or the corporation, or may remain unfunded. (3) When property rights are weak, no breakaways occur in equilibrium; local spillovers and strong product market competition increase the likelihood that research projects will get funding. (4) The equilibrium sequence of R&D finance need not be first-best efficient. (5) In equilibrium, and controlling for the strength of property rights, VCs finance projects that are more profitable on average. 相似文献

Artists face choices between the pecuniary benefits of selling to the market and the nonpecuniary benefits of creating to please their own tastes. We examine how changes in wages, lump-sum income, and capital-labor ratios affect the artist's pursuit of self-satisfaction versus market sales. Using our model of labor supply, we consider the economic forces behind the high/low culture split, why some artistic media offer greater scope for the avant-garde than others, why so many artists dislike the market, and how economic growth and taxation affect the quantity and form of different kinds of art. 相似文献

We present a model of coups in autocracies. Assuming that policy choices cannot be observed but are correlated with the short-run performance of the economy we find that: (a) the threat of a coup disciplines autocrats; (b) coups are more likely in recessions; (c) increasing per capita income has an ambiguous effect on the probability of a coup. The implications of the model are consistent with the evidence. On average, one recession in the previous year increases the probability of a coup attempt by 47 percent. By contrast, the effect of the level of per capita income is weak. 相似文献
