We model strategic interaction in a differentiated input market as a game among two suppliers and n retailers. Each one of the upstream firms chooses the specification of the input which it will offer.Then, retailers choose their type from a continuum of possibilities. The decisions made in these two first stages affect the degree of compatibility between each retailer's ideal input specification and that of the inputs offered by the two upstream firms. In a third stage, upstream firms compete setting input prices. Equilibrium may be of the two-vendor policy or of the technological monopoly type.  相似文献

Few studies have examined customers' beliefs and intentions across different self-service technology channels and different intended uses of these channels. The present work integrates (a) technology acceptance variables (b) trusting beliefs and trusting intention as two distinct constructs, (c) level of customers' information about the channel, in order to test their effect on use intention for two channels, Internet and phone banking, and three banking transactions. Findings from a sample of 762 bank customers reveal that patterns of adoption are quite similar for the two channels but differ across transactions. Furthermore, the trusting intention has a strong mediating role between trusting beliefs and technology-acceptance variables on one hand, and intention to use these channels on the other hand. Several implications for developing intention to use technology-based channels are discussed.  相似文献

A decision support model (DSM) is presented and implemented in order to identify probable and realistic export opportunities for Greece. The aim of the model is to select those combinations of products and countries of destination (markets) that are attractive based on widely recognized criteria (such as country risk indicators, macroeconomic data, market shares, accessibility of destination country, degree of market concentration, etc.). The DSM consists of a filtering process during which the less attractive export opportunities are successively eliminated in order to focus on those markets that have the desired characteristics. International trade data at the HS six-digit level up to 2011 where used. The results indicate that there exist significant export opportunities for Greece. Export opportunities are listed and categorized according to criteria such as the market characteristics of the destination country and Greece’s market share.  相似文献

Greek public pension funds can invest up to 23% into risky assets and are not allowed to invest outside Greece. This paper seeks to investigate the costs of investment constraints on pension fund portfolios. In particular we try to quantify the losses that portfolios suffer due to under-diversification and sub-optimal asset allocation. We find that the high concentration of Greek equity portfolios imposes a substantial return and utility loss which is further increased when the lack of international diversification is taken into account. Restricting the weight of equities to 23% of the total portfolio, leads to sub-optimal asset allocation that costs as much as 2% (3%) per annum compared to a balanced domestic (global) benchmark.  相似文献

Option-Implied Risk Aversion Estimates   总被引:4,自引:0,他引:4  
Using a utility function to adjust the risk‐neutral PDF embedded in cross sections of options, we obtain measures of the risk aversion implied in option prices. Using FTSE 100 and S&P 500 options, and both power and exponential‐utility functions, we estimate the representative agent's relative risk aversion (RRA) at different horizons. The estimated coefficients of RRA are all reasonable. The RRA estimates are remarkably consistent across utility functions and across markets for given horizons. The degree of RRA declines broadly with the forecast horizon and is lower during periods of high market volatility.  相似文献

This paper examines the transmission of GDP growth and GDP growth volatility among the G7 countries over the period 1960Q1 – 2010Q4, using a multivariate GARCH model and volatility impulse response functions (VIRFs) to identify the source, magnitude and the duration of volatility spillovers. Results indicate the presence of positive own-country GDP growth spillovers in each country and cross-country GDP growth spillovers among most of the G7 countries. In addition, the large number of significant own-country output growth volatility spillovers and cross-country output growth volatility spillovers indicates that output growth shocks in most of the G7 countries affect output growth volatility in the other remaining countries. An additional finding is that the duration of output growth volatility spillovers has increased over time from some seven quarters in the 1970s to some ten quarters during the recent crisis, which is likely to be due to the increased integration of goods and financial markets.  相似文献

In this study Malmquist productivity indexes are used to evaluate the performance of acute hospitals in the UK over the period after the introduction of the internal market in the National Health Service in 1991. The indexes are computed using nonparametric programming, known as Data Envelopment Analysis, and they are decomposed into multiple component measures to give insights into the trends in hospital performance. Overall it is found that productivity regressed in the year after the reforms but progressed thereafter so that overall there was a net progress both as far as the inputs and costs are concerned. Productivity progress is mainly due to overall efficiency progress, which in turn is mostly attributed to allocative efficiency improvements. Technical change resulted in a small reduction in the amount of inputs used but also at higher production costs, because of a worsening in the match between input mixes and relative input prices. However, it is suggested that the gains in productivity are not high enough to argue that the internal market has had a significant impact on productivity. Finally, it is argued that the methodologies employed here can be a valuable evaluative and managerial tool in the context of the new NHS reforms about to be introduced.  相似文献

Building on and extending prior research, we propose a comprehensive framework which posits that free cash flow moderates the impact of corporate governance on financial diversification. We argue that because it increases CEO perceived risk, alignment devices increase rather than decrease financial diversification. In a sample of 59 publicly traded French corporations during 2000–2006, we show that financial diversification negatively impacts shareholder return and firm value. We obtain support for several of our hypotheses: at high levels of free cash flow, CEO variable compensation increases financial diversification, whereas chairman/CEO non‐duality reduces it. In contrast, independent directors increase financial diversification at low values of free cash flow (although weakly). We also find that ownership concentration only reduces financial diversification when free cash flow is low.Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

This paper seeks to provide a new economic strategy for the United States while considering a range of development-related impediments to the country’s recent economic performance. It is argued here that strategic industrial policy needs to come to the center stage if local production growth, competency upgrading, and competitiveness improvement are to be aggressively pursued. The first section outlines the present context of the US economy by discussing economic and socio-cultural aspects. The second main section frames an alternative development paradigm for the United States. Policy recommendations are discussed in the third section. Some brief conclusions end the paper.  相似文献
