The Coevolution of the Real and Financial Sectors in the Growth Process   总被引:4,自引:0,他引:4  
The role of debt and equity changes over time and with the levelof development. What are these changes, and why should theysystematically occur across different countries and time periods?This article characterizes financial innovation as a dynamicprocess that both influences and is influenced by the developmentof the real sector. It focuses on the emergence and developmentof equity markets, using a model that allows for growth andfor capital accumulation that is financed externally througha combination of debt and equity. As an economy develops, theaggregate ratio of debt to equity will generally fall; yet,debt and equity remain complementary sources for the financingof capital investments. The results suggest how various governmentpolicy actions might affect capital accumulation and equitymarket activity.  相似文献

This paper uses logistic regression to construct a one‐quarter ahead prediction model for classical business cycle regimes in the UK. The binary dependent variable is obtained by applying simple mechanical rules to date turning points in quarterly real GDP data from 1963 to 1999. Using a range of real and financial leading indicators, several parsimonious one‐quarter‐ahead models are developed for the GDP regimes, with model selection based on the SIC criterion. A real M4 variable is consistently found to have predictive content. One model that performs well combines this with nominal UK and German short‐term interest rates. The role of the latter emphasises the open nature of the UK economy.  相似文献

This article reports the results of a study of innovation and product development at 245 manufacturing sites in the UK and Germany. It examines the relationship between design and performance and the competitiveness of the UK and Germany in design and manufacturing. Overall, few sites reached "world-class" standards - 9% in Germany and 3% in the UK, although many sites were not far below these standards.  相似文献

After highlighting some of the key issues and positions in the debate around appropriate preventive regulation, the paper presents a number of observations directed at the proponents of greater self-regulation. These observations confront directly a number of familiar, but often unchallenged, arguments for self-regulation. More centrally we address claims concerning, the extent to which the chemicals industries have a good and improving ‘safety’ record; and whether the sector consists of companies both motivated and capable in the context of effective crisis and disaster management. Lastly, the paper sets out some ‘new directions’ for the nature and role of regulation in the effective prevention of crises. Thus the paper indicates a number of regulatory developments which are distinct from any shift towards greater self-regulation, but which would result in more effective crisis and disaster prevention in the UK chemicals industries and, indeed, beyond that specific sector.  相似文献

On the Role of Weight Restrictions in Data Envelopment Analysis   总被引:3,自引:3,他引:0  
This paper examines the role that weight restrictions play in Data Envelopment Analysis (DEA). It is argued that the decision to include a factor (input or output) in a DEA model represents an implicit judgement that the factor has a non-trivial weight. It therefore seems perverse to allow DEA to assign a trivial weight to that factor in assessing the efficiency of a unit. There is therefore a strong case for imposing restrictions on factor weights. However, many existing methods of weight restriction are in practice unwieldy. This paper proposes an alternative approach we term contingent weight restriction which is both practical and intellectually consistent with the DEA philosophy. The paper explores the implications of alternative methods of weight restriction using simulated data from a well known production process.  相似文献
