I discuss the role to be played by central banks in payment systems by way of an oligopoly model of a payments market where
firms exert negative risk externalities upon each other. A central bank participating actively in this market is modelled
as benign in two ways: exerting less externalities than other banks and maximizing welfare rather than profit. Because other
banks react strategically to the central bank’s presence due to its low externalities, there is a risk that it backfires,
with these other banks’ taking more risky positions than if the central bank were not there. The proper role of the central
bank may actually be to stay out. 相似文献

This paper contains some of the main results of an investigation into the use of educated manpower in Norwegian industries. An input-output model with labour inputs specified by education is presented. Per unit of final delivery, Norwegian exports in 1960 used relatively less labour, and less educated labour, but more capital (measured by depreciation) than the other categories of final demand. But when the use of labour is compared to the income created by the final deliveries, the differences are much smaller. 相似文献

This paper generalizes the informational environment of the Rock model to address empirical evidence and conjectures that cannot be addressed within the standard model based on informed and uninformed investors such as underpricing being positively related to market returns observed prior to the IPO, the number of IPOs being positively related to market returns, underpricing being partly predictable based on public information, and the return to uninformed participation being negative overall but positively related to market returns observed prior to the IPO. Finally, the model suggests that a positive relation between market returns and underpricing need not represent an inefficiency in the pricing of IPOs. 相似文献

Recent work by Clements and Hendry elucidate why forecasting systems that are in terms of differences, dVARs, can be more accurate than econometric models that include levels variables, EqCMs. For example, dVAR forecasts are in some cases insulated from parameter non-constancies in the long run mean of the cointegration relationships. In this paper, the practical relevance of these issues are investigated for RIMINI, the quarterly macroeconometric model used in Norges Bank (Central Bank of Norway), an example of an EqCM forecasting model. We develop two dVAR versions of the full RIMINI model and compare EqCM and dVAR forecasts for the period 1992.1–1994.4. We also include forecasts from univariate dVAR type models. The results seem to confirm the relevance of the theoretical results. First, dVAR forecasts appear to provide some immunity against parameter non-constancies that could seriously bias the EqCM forecasts. Second, the misspecification resulting from omitting levels information generates substantial biases in the dVAR forecasts 8 and 12 quarters ahead. 相似文献

In an ultimatum bargaining experiment, we study how subjects bargain over the returns to their investments of money and time. The most notable finding is that a third of the subjects demand no compensation for their time investments, whereas almost all subjects demand compensation for equally costly monetary investments. 相似文献

Is there a credit channel for monetary policy? Has the deregulation of financial markets had any temporary or permanent effects on the monetary transmission mechanism? We present empirical evidence on these issues for Norway by estimating a dynamic system of money, credit, real income and inflation. We find that the deregulation process has not caused any permanent shifts in the long‐run demand functions. Within a small simultaneous dynamic model, there is some evidence for the credit view of the monetary transmission mechanism, as both credit and money exhibit strong and stable effects on aggregate demand.

Industrial companies today are becoming increasingly service-oriented and therefore need to shift from selling hardware to valuing services and managing customer relationships. A new and particularly significant challenge for these companies is how to initiate relationships which is an issue that has received surprisingly limited scientific attention. The aim of this study is to develop a conceptualization that explores the dynamics in the relationship initiation process in service-dominant settings. Narratives from three sellers of professional services, augmented with narratives from a buyer's view, form the empirical basis of the study. The dynamics in the relationship initiation process are clarified with three new concepts: status, converter, and inhibitor. The paper concludes with implications of the new conceptualization and suggestions for future research. 相似文献

The significance of mindsets is apparent in everyday business life. As today’s managers and companies face uncertainty and disruptive change in the business environment and markets, there is a growing need to understand and strategically address such change. This becomes challenging when disruptive market forces confront the institutional logic or rules of the game based on collectively acquired experience of doing business in the given field. In overcoming such challenges, managers’ hidden reasoning remains an untapped potential while their existing mindset influences what they attend to and what they decide to do. This article elaborates a diagnostic framework, accompanied by a tool to help managers make sense of disruptive markets and reflect individually and collectively on possible courses of action. The framework has two principal dimensions—strategic scope and focus—that are further divided into three business elements of strategic market-oriented management: offering, customer, and market. The tool offers a practical means of profiling individuals’ mindsets. In increasingly dynamic business environments, reflection capabilities represent a new source of competitive advantage. 相似文献

Abstract The concept of optimum stratification was introduced in a paper published in this journal 1950 (1), where as well a technique was devised to determine the condition for optimum stratification. This technique is based upon the representation of the population by a density function ? (y). The variance V ( y ) of the estimate y for a specific type of allocation of the sample to the k strata is then dealt with as a function of the points Yi of stratification. By solving the equations: the conditions that these points Yi must fulfil in order to make V ( y ) a minimum are arrived at. In a second paper (2) further results were given. 相似文献
