In this paper, we introduce an analytical perturbative solution to the Merton–Garman model. It is obtained by doing perturbation theory around the exact analytical solution of a model which possesses a two-dimensional Galilean symmetry. We compare our perturbative solution of the Merton–Garman model to Monte Carlo simulations and find that our solutions perform surprisingly well for a wide range of parameters. We also show how to use symmetries to build option pricing models. Our results demonstrate that the concept of symmetry is important in mathematical finance.  相似文献

Past research on gambling behavior has focused largely on cognitive and affective explanations, but has not explored the influence of past gambling behavior or habit. In this study, it was hypothesized that gambling behavior followed predictable patterns based on past behavior. We found that these patterns could be described by the negative binomial distribution (NBD) and NBD–Dirichlet models at game and category levels, respectively. An empirical study using the 1999 Australia Productivity Commission survey dataset provided some support for the usefulness of these models in describing gambling consumption. The paper explores the implications for identifying problem gambling and influencing gamblers’ behavior.  相似文献

Abstract

Following the Common Agency approach to political equilibrium, we examine how domestic interest groups can influence national policies toward FDI and how the choice of instrument by the government can affect lobbying activities. Domestic firms lobby for lower subsidies when a discriminatory subsidy on FDI is applied. However, when a subsidy is applied uniformly to both groups, they may lobby for higher subsidies. The nature of lobbying is also different for proportional and lump-sum profit subsidies when uniformly applied. The qualitative effect of the number of domestic firms or the degree of corruption on the equilibrium depends on the choice of instruments. Finally, with the help of numerical simulation, we examine whether there is any potential conflict between the government and the lobby groups on the choice of the instrument.  相似文献

A number of studies have shown that defence contractors have exhibited a marked reluctance to diversify away from defence and develop civil applications. However, the aero engine manufacturer Rolls-Royce is one defence contractor to which this does not apply. Over a 60-year period it has moved from being almost entirely dependent on defence work to a point where defence now constitutes barely one-fifth of its turnover. This article examines the development of the company's civil aerospace business over the period since 1945. It focuses specifically on the strategies used by Rolls-Royce in the civil aerospace field. These strategies are explored in the context of changes in market conditions, technology, and governance arrangements. The effectiveness of the various strategies, including their contribution to the company's current position, is evaluated.  相似文献

This paper provides an empirical evaluation of the five-factor model recently presented by Fama and French (2015a) that augments the traditional three-factor model with two new factors related to profitability and investment, taking into account the bias in mean returns induced by noise in prices. Using an extensive sample over the period 1997 to 2015, we find that the five-factor model consistently outperforms the three-factor model in the Chinese equity market. In contrast to the findings in Fama and French (2015a), both value and profitability factors are important, while the investment factor is found to be redundant for describing average returns in our sample. With respect to the double-sorted left-hand-side (LHS) portfolios, the main problem with the five-factor model is its failure to fully capture the high average returns of stocks whose returns perform like those of growth firms that invest conservatively due to low profitability. On the other hand, although we find mixed results in the three-dimensional sorting, the LHS portfolios with extremely low average returns are those that cause serious problems for the five-factor model.  相似文献

Literature has widely acknowledged that the main purpose of company–customer relationships is to create value for both sides. Satisfaction, loyalty behaviours, and reputation are considered customer-related performance measures. However, research has not fully uncovered the complicated interrelationships among these constructs, particularly with regard to multiple mediations and in the case of manufacturer corporate brands. To examine the hypothesised relationships between and among our constructs, we go beyond the commonly studied single mediator and test a four-path model (three mediators in a series). The results indicate that satisfaction and loyalty behaviours mediate the relationship between customer value and reputation. In theoretical terms, we contribute to the literature by showing that customer value creation is a reputation-building strategy that bridges the gap among product, brand, and corporate performance levels.  相似文献

The Zobele, located in Trento, Northern Italy, was founded in 1919 by Enrico Zobele Sr., who became famous when he invented his first “killer product” in 1930—flypaper. After the Second World War, the bombed-out factory was rebuilt by his sons, Luigi and Fulvio, who introduced new products for home hygiene and home care. The company globalized under the joint leaderships of Chief Executive Enrico Jr., son of Luigi, and Franco and Giovanni, sons of Fulvio. In 2001, Zobele Chemical Industries reported sales of US$75 million with profits of US$5.1 million. The company had 700 employees, factories in Italy, Spain, Brazil, Paraguay, India, Hong Kong, Mexico, and Malaysia with continuing expansions in Italy and China. This is a case study of the Zobele family and Zobele Chemical Industries, their past history, and present status. It centers on the challenges they face in ensuring global leadership in their served market niches, while maintaining the continuity of family ownership and control. This case presents the practical implications for family enterprises in their attempts to meet the challenges of a globalized marketplace.  相似文献

Increasing the employment of older working-age adults can entail numerous benefits, including higher individual incomes, higher future pension entitlements, stimulation and retention of cognitive skills, and better mental health. Policy makers must implement interventions designed to encourage the re-employment of older unemployed people.  相似文献

This North–South model of Schumpeterian endogenous growth combines a market, productivity and knowledge effect. Depending upon the interaction of these effects, various convergent and divergent South–North growth paths occur: for example, full or partial convergence of the Southern technology level to the Northern one, conditional convergence or divergence depending upon the Southern initial technology level and absorptive capacity, higher or lower as well as decreasing or increasing growth rates during the phase of catching up, and equal or higher growth rates of the South compared to the North after catching up. This set of growth paths can better explain the diversity of the empirical observations for economies at different income and technology levels than those generated by existing models. In this new model, convergence based on North–South trade and associated flows of patents (innovations) is guaranteed if the knowledge effect dominates the productivity effect. A larger Southern market expands the area of convergence and can prevent divergence. Not only a larger Southern market, but also a higher Southern steady state growth rate benefit the North so that convergence is desirable for both, the South and the North.  相似文献

We employ archival evidence to investigate events culminating in the nationalisation of the Anglo-Iranian Oil Company (AIOC) in 1951, which followed disagreements over profit allocations arising from a previously negotiated concession. The case study expands the traditional obsolescing bargain model (OBM) by accommodating the use and impact of accounting information in negotiation contexts. The analysis reveals that managerial control and the deployment of accounting information by the AIOC temporarily strengthened its bargaining power vis-à-vis the Iranian government leading up to the nationalisation crisis, demonstrating the potential importance of these new dimensions in wider contexts.  相似文献

Recent developments in the global business environment have led to important changes in accounting/auditing regulations, and have implications for the business school curriculum. While many of these issues are covered in advanced accounting courses, generally taken only by majors, the issues are sufficiently important that nonaccounting majors, at both the graduate and undergraduate level, should be aware of these issues as well. Recent developments favoring the adoption of International Financial Reporting Standards (IFRS) in the United States provide an overall compelling context for incorporating these standards into the business curriculum. The purpose of this article is to provide a road map for such incorporation.  相似文献

This paper is an empirical study of inter-industry and inter-temporal variations in entry of new firms using longitudinal data covering all manufacturing establishments in Lower Saxony between 1979 and 1989. Patterns of entry are reported for 29 industries based on numbers of new firms, gross rates of entry, and entry intensities (shares of employees) in different types and size classes of new firms. Entry varies considerably between firm types, industries, and over time. Focussing on entry by small single firms an empirical model is applied to search for industry characteristics that are highly correlated with entry. Pooling of cross-section and time-series data allows to control for influences of varying macroeconomic conditions and unobserved industry characteristics. A highly robust estimation method is applied for the first time in a study of entry rates, and it turns out that extreme observations often have large effect on the results. Entry intensity tends to be positively related to industry growth, concentration, and high unemployment, but negatively to high interest rates, profits, and (insignificantly) to intensive use of capital and R&D. I plead for further research vialearning by asking those who are doing.This paper is part of the research project Production, Employment Growth, and Exports by Lower Saxonian Firms. The computations based on the establishment level data from the official surveys of the manufacturing sector were made possible by a special arrangement between the Ministry of Economics, the Statistical Office, and the Labor Research Group at the Department of Economics, Hannover University. I thank Uwe Rode from the Lower Saxonian Statistical Office for preparing the longitudinal establishment level data base. Financial support from research funds provided by the state of Lower Saxony is gratefully acknowledged.  相似文献

The primary objective of this study is to propose and investigate the integrative model which was formulated by modifying and extending the Triandis model (TRIANM); this explores the structural relationships among knowledge-sharing enablers, process, and outcomes in hotels from a holistic perspective. The hypotheses are examined with data from 327 employees in 10 five-star hotels in Busan, Korea. Anticipated usefulness and reciprocal relationships are confirmed as the two most important enablers of employees' knowledge-sharing behaviour. Other significant enablers include facilitating conditions and social factors. New enablers, enjoyment in helping others and knowledge self-efficacy, that we have added to the TRIANM are also found to be significant. The path from knowledge-sharing behaviour to organizational innovation capability, the path from organizational innovation capability to organizational performance is found to be significant, respectively. The findings and theoretical and practical implications are then discussed.  相似文献

Firm growth is almost universally portrayed as a good thing, and is commonly used as a measure of success. Applying resource-based reasoning, we argue that growth is often not a sign of sound development. Specifically, we hypothesize that firms which grow without first securing high levels of profitability tend to be less successful in subsequent periods compared to firms that first secure high profitability at low growth. Empirical tests using two large, longitudinal data sets confirm that the profitable low growth firms are more likely to reach the desirable state of high growth and high profitability. In addition, they have a decreased risk of ending up performing poorly on both performance dimensions compared with firms starting from a high growth, low-profitability configuration. The results suggest that academics, managers, investors and policy-makers may benefit by adopting a more nuanced view of firm growth that explicitly incorporates its intricate relationship with profitability.  相似文献

In discussing the nexus between innovations and market structure it is often argued that industry characteristics (called opportunities) might play an important role as determinants of innovation, and that simultaneity rather than one-way causality prevails. We consider a three-equation model for innovation, advertising, and concentration. Based on pooled cross-section time-series data for 26 German manufacturing industries we estimate single equation models with and without fixed industry and/or time effects (to control for unobservable industry or time effects, respectively) and simultaneous equation systems including fixed effects, and controlling for extreme cases (outliers) or not. Furthermore, we use two different measures for innovations, i.e., the percentage of shipments due to new products, and the percentage of firms which classified themselves as innovators. Our results can be summarized as follows: (1) The firm size has no significant effect on innovation. One can, therefore, not conclude from this data set that large firms are more innovative than small ones; (2) unobservable industry effects do matter; (3) the treatment of outliers does matter; (4) simultaneity does matter (5) the way innovations are measured does matter; (6) different stories could be told based on the results of the systems of interdependent equations estimated.Earlier versions of this paper were presented at the annual meeting of the committee of industrial economists of the Verein fuer Socialpolitik at Hohenheim University in March, 1990, and at the 1990 conferences of the European Economic Association and the European Association for Research in Industrial Economics in Lisboa. We would like to thank participants of these meetings and three anonymous referees for helpful comments. A more complete version of the paper with a set of tables for the results of all computations is available from the authors on request.  相似文献

In this paper, we focus on the pricing issue of four types of executive stock options (ESOs) in the Heston–Nandi generalized autoregressive conditional heteroskedasticity option pricing model. Based on the derived benchmark strike prices in the proposed framework, we obtain the closed-form pricing formulae for four types of ESOs. In the numerical part, we investigate the sensitivity and cost efficiency of ESOs and suggest that systematic risk (stock β) and the fraction of wealth invested in restricted stock could impede the cost efficiency of ESOs.  相似文献

This paper adopts industry life cycle approaches to understand better the changing rationales for product strategy development in the worldwide mobile phone industry. Based on both primary and secondary sources, we find that mobile phone manufacturers have radically changed their product strategy over the industry life cycle in response to various factors, such as the intense global competition and the need to respond rapidly to changes in technology and mass-consumer preferences. We also find that, when the mobile phone industry entered a stage of shake-out in the 2000s, contrary to the prediction of the classical product–process life cycle model, mobile phone manufacturers focused their strategy not only on process but also on product innovations. The continuous launch of new and advanced product technologies served mainly to stimulate the demand for replacement purchases. We observe this unexpected key role of product innovation to be very strong also in the stage of industry maturity.  相似文献

This paper uses a new classification of employment in the USA based on hierarchical cluster analysis to analyze trends in employment from 1998 to 2005. Measures of growth in employment at the state level are presented, along with selected analyses of correlates of employment change. Specialization in key clusters is related to state growth rates, and the markets of the clusters are identified through the use of input–output data. Shifting consumption patterns are examined for clusters with strong household markets.  相似文献

The study examines the relationships between consumer trust (cognitive and affective), perceived value (utilitarian and hedonic), and loyalty behavioral intentions (repurchase and advocacy) in a two-dimensional (affect- and rational-based) consumer–service provider model. It provides an alternative theoretical representation of consumer behavior in service relationships and implications for service providers about consumers' loyalty intentions. A mail survey analyzed by SEM supports the model of loyalty as a function of consumers' expressive and instrumental responses resulting from intrinsic and extrinsic perceptions of trust and heuristic and rational-based perceived value. Implications for designing loyalty programs are explored and future research opportunities recommended.  相似文献
