The efficiency-enhancing role of the vengeance motive is illustrated in a simple social dilemma game in extensive form. Incorporating behavioral noise and observational noise in random interactions in large groups leads to seven continuous families of (short run) Perfect Bayesian equilibria (PBE) that involve both vengeful and non-vengeful types. A new long run evolutionary equilibrium concept, Evolutionary Perfect Bayesian Equilibrium (EPBE), shrinks the equilibrium set to two points. In one EPBE, only the non-vengeful type survives and there are no mutual gains. In the other EPBE, both types survive and reap mutual gains. 相似文献
Building upon social and racial identity theories, this study examines the role of positive relational climate in predicting
interpersonal helping behaviors (IHBs) at the workplace. Within this context, we examine both the role of mutual respect and
psychological safety as exemplars of positive relational climate, and the mediating role of organizational identification
(OI). The study also recognizes the importance of individual differences by examining racial differences in OI and IHBs. Results
support the hypotheses and strengthen claims of social and racial identity theories. 相似文献
Acquisitions and alliances are two pillars of growth strategy. But most businesses don't treat the two as alternative mechanisms for attaining goals. Consequently, companies take over firms they should have collaborated with, and vice versa, and make a mess of both acquisitions and alliances. It's easy to see why companies don't weigh the relative merits and demerits of acquisitions and alliances before choosing horses for courses. The two strategies differ in many ways: Acquisition deals are competitive, based on market prices, and risky; alliances are cooperative, negotiated, and not so risky. Companies habitually deploy acquisitions to increase scale or cut costs and use partnerships to enter new markets, customer segments, and regions. Moreover, a company's initial experiences often turn into blinders. If the firm pulls off an alliance or two, it tends to enter into alliances even when circumstances demand acquisitions. Organizational barriers also stand in the way. In many companies, an M&A group, which reports to the finance head, handles acquisitions, while a separate business development unit looks after alliances. The two teams work out of different locations, jealously guard turf, and, in effect, prevent companies from comparing the advantages and disadvantages of the strategies. But companies could improve their results, the authors argue, if they compared the two strategies to determine which is best suited to the situation at hand. Firms such as Cisco that use acquisitions and alliances appropriately grow faster than rivals do. The authors provide a framework to help organizations systematically decide between acquisition and alliance by analyzing three sets of factors: the resources and synergies they desire, the marketplace they compete in, and their competencies at collaborating. 相似文献
The Solow (1956Solow, R. 1956. A contribution to the theory of economic growth. Quarterly Journal of Economics, 70: 65–94. [Crossref], [Web of Science ®], [Google Scholar]) growth model is extended with an endogenous growth framework to estimate the effects of trade openness on the Steady State Growth Rate (SSGR). Estimates of the augmented production functions are used to compute the SSGRs for Singapore, Malaysia, Hong Kong, India and Thailand. Good policies that increase the growth effects of openness is also tested with an interactive term. Our results show that Singapore has the highest SSGR of 2.75%, followed by Hong Kong and Thailand with 2.5%. India and Malaysia have lower SSGRs of 1.7% and 0.5%, respectively. 相似文献
This study examines the relationship between financial development and economic growth in India for the period 1951–52 to 1995–96. The long-run equilibrium and short-run dynamic models are estimated using financial interrelations ratio and new issue ratio as the measures of financial development, a la Goldsmith (1969Goldsmith, RW. 1969. Financial Structure and Development, New Haven: Yale University Press. [Google Scholar]). The Johansen (1991Johansen, S. 1991. Estimation and hypothesis testing of cointegration vectors in Gaussian vector autoregressive models’. Econometrica, 59: 1551–80. [Crossref], [Web of Science ®], [Google Scholar]) estimator rejects the null of zero cointegrating vector and shows the presence of long-run equilibrium relationship between financial development and economic growth. The error correction model, impulse response and variance decomposition analyses (Sims, 1980Sims, CA. 1980. Macroeconomics and reality. Econometrica, 48: 1–48. [Crossref], [Web of Science ®], [Google Scholar]), and the Toda and Yamamoto (1995Toda, HY and Yamamoto, T. 1995. Statistical inference in vector autoregressions with possibly integrated processes. Journal of Econometrics, 66: 225–50. [Crossref], [Web of Science ®], [Google Scholar]) estimator show the presence of bidirectional Granger-causality between financial development and economic growth. The presence of bidirectional Granger-causality suggested by these estimators points towards the possible problem of endogeneity and simultaneity bias in the growth models that examine the contemporaneous effect of financial development on economic growth. The economic reforms that started since July 1991 emphasized on the liberalization and development of financial sector to supplement the efforts aimed at achieving high economic growth in India. 相似文献
During the 1990s the cooperative dairy processing sector in India was exposed to greater competition from private sector plants. In this paper we measure cost efficiency (decomposed into technical and allocative efficiency) at the dairy plant level in the cooperative and private sectors in India. Two efficiency measurement methods are used: stochastic frontier analysis (SFA) and data envelopment analysis (DEA). The study utilizes an (incomplete) panel data sample of 23 plants, comprising 13 cooperative plants and 10 private plants, observed between 1992/93 and 1996/97. Our results indicate that cooperative plants are more cost efficient than private plants, although this difference is insignificant at the 5 per cent level. Furthermore, we observe that the cost efficiency of cooperative plants has not improved since market liberalization in 1991. These results suggest that the liberalization policy has not yet realized its expected benefits, and also cause us to question the general expectation that private operators will have efficiency advantages relative to cooperatives. 相似文献
This research paper examines one-day-ahead out-of-sample performance of the volatility smirk-based options pricing models, namely, Ad-Hoc-Black–Scholes (AHBS) models on the CNX Nifty index options of India. Further, we compare the performance of these models with that of a TSRV-based Black–Scholes (BS) model. For the purpose, the study uses tick-by-tick data. The results on the AHBS models are highly satisfactory and robust across all the subgroups considered in the study. Notably, a daily constant implied volatility based ad-hoc approach outperforms the TSRV-based BS model substantially. The performance of the ad-hoc approaches improves further when the smile/smirk effect is considered. For the estimation of the implied volatility smile, we apply three weighting schemes based on the Vega and liquidity of the options. All the schemes offer equally competing results. The major contribution of the study to the existing literature on options pricing is in terms of the ex-ante examination of the ad-hoc approaches to price the options by calibrating volatility smile/smirk on a daily basis.
The economy of Fiji has witnessed a pervasive role of information and communications technology (ICT) on one hand and an increase in lifestyle diseases on the other. The government however has put in policies to exploit the gains from ICT and increased budget allocation to combat some of the burgeoning health problems in their effort to modernize the economy. In this paper, we explore the short-run and long run effects of health expenditure and ICT on per worker output within the augmented Solow framework (Q J Econ 70:65–94, 1956) and the autoregressive distributed lag bounds procedure (Pesaran et al. in J Appl Econ 16:289–326, 2001) over the period 1979–2010. The results show that health expenditure has a positive and significant effect in the short-run only (0.11 %). ICT has positive and significant effect both in the short-run (0.90 %) and the long-run (0.62 %). Further, the Granger-causality tests reveals a strong bi-directional causality between health expenditure and per worker output, a unidirectional strong causation from capital per worker to ICT development, and a weak causation from ICT to per worker output. 相似文献
