In the framework of classical risk theory we investigate a model that allows for dividend payments according to a time-dependent linear barrier strategy. Partial integro-differential equations for Gerber and Shiu's discounted penalty function and for the moment generating function of the discounted sum of dividend payments are derived, which generalizes several recent results. Explicit expressions for the nth moment of the discounted sum of dividend payments and for the joint Laplace transform of the time to ruin and the surplus prior to ruin are derived for exponentially distributed claim amounts.  相似文献

Summary In a previous article I explained the gradual deterioration of Austria's current balance in the seventies and its pronounced deficit in 1976 and 1977 within the framework of the relative absorption approach by reference to capacity utilization rates that were high compared to those of other countries. The high utilization rates in turn were the consequence of an expansive economic policy, in particular of an expansive fiscal policy. Guger-Wörgötter, on the other hand, interpret the deficit in the Austrian current balance as the result of weak foreign demand and view the budget deficit as an attempt to compensate for insufficient aggregate demand; they conclude that full employment policies should be continued disregarding the economic development abroad. The present paper presents additional evidence that the deficit in the current balance is attributable to the fact that Austria's economic policy maintained a higher rate of capacity utilization than abroad. Such a policy serves a useful purpose and can be financed by foreign currency reserves only in the case of a cyclical demand deficiency; in the long run, however, it can be sustained at best only under a regime of flexible exchange rates (continuing devaluation).  相似文献

Many companies now run boot camps--comprehensive orientation programs designed to help new hires hit the ground running. They're intense and intimidating, and new employees emerge from them with strong bonds to other recruits and to the organization. But at Trilogy, organizational consultant Noel Tichy discovered one program that's a breed apart. In this article, Tichy gives us a detailed tour of Trilogy's boot camp, Trilogy University, to demonstrate why it's so different--and so effective. Like the best boot camps, it serves as an immersion in both the technical skills new recruits will need for their jobs and Trilogy's corporate culture, which emphasizes risk-taking, teamwork, humility, and a strong customer focus. But this is a new-employee orientation session that's so fundamental to the company as a whole that it's presided over by the CEO and top corporate executives for fully six months of the year. Why? In two three-month sessions, these top executives hone their own strategic thinking about the company as they decide what to teach the new recruits each session. They also find the company's next generation of new products as they judge the innovative ideas the recruits are tasked with developing--making the program Trilogy's main R&D engine. And they pull the company's rising technical stars into mentoring roles for the new recruits, helping to build the next generation of top leadership. After spending months on-site studying Trilogy University, Tichy came away highly impressed by the power of the virtuous teaching cycle the program has set in motion. Leaders of the organization are learning from recruits at the same time that the recruits are learning from the leaders. It's a model, he argues, that other companies would do well to emulate.  相似文献

ABSTRACT

Infrastructure is a key area of public investment and development cooperation, and can be seen as a critical enabler of trade and integration. Stakeholders increasingly demand evidence on the effectiveness of investments in infrastructure such as railways, in part because these investments typically lock in development patterns for decades. In this article we take stock of the main findings, methodological approaches, gaps and caveats of the current literature with a focus on railways. Based on this analysis, we present a methodology for an impact evaluation framework which builds on existing knowledge and addresses some of these shortcomings. Beyond the dearth of empirical evidence on the socio-economic and environmental impacts of infrastructure, we discuss critiques of the currently prevalent methodological toolbox. Using a real-world railway project in India, the Konkan Railway, we exemplify how a rigorous quantitative impact assessment can integrate inter-disciplinary and mixed-methods features to address these issues. Specifically, we apply different quasi-experimental techniques on the level of intermediate and ultimate outcome and impact indicators, using census, survey and satellite data and information from document analyses, interviews and focus group discussions. We draw on insights from economics, sociology, engineering and geography in making sense of large infrastructure projects and their impacts.  相似文献

Managing strategic change is increasingly a way of life for organizations faced with the turbulent economic, political, and cultural forces of the 1980s. To manage such change, organizations and their managers will have to confront basic questions regarding the organization's technical, political, and cultural foundations. The technical questions include: What business(es) should we be in? How should we be organized to accomplish our strategy? What kinds of people do we need, and how will they be acquired, developed, and rewarded? The political questions include: Who gets to influence the mission and strategy of the organization? How is power allocated both vertically and horizontally across the organization? Who gets promoted to what key positions? The cultural questions include: What values and beliefs are necessary to support the organization's strategy? What subcultures are desirable, and should there be an overarching corporate culture? How should the human resources system shape and mold the culture?  相似文献

Before the breakup of the Bell System, U.S. telephone companies were permitted by law to ask for security deposits from a small percentage of subscribers. The companies used statistical models to decide which customers were most likely to pay their bills late and thus should be charged a deposit, but no one knew whether the models were right. So the Bell companies made a deliberate mistake. They asked for no deposit from nearly 100,000 new customers randomly selected from among those who were considered high risks. Surprisingly, quite a few paid their bills on time. As a result, the companies instituted a smarter screening strategy, which added millions to the Bell System's bottom line. Usually, individuals and organizations go to great lengths to avoid errors. Companies are designed for optimum performance rather than for learning, and mistakes are seen as defects. But as the Bell System example shows, making mistakes--correctly--is a powerful way to accelerate learning and increase competitiveness. If one of a company's fundamental assumptions is wrong, the firm can achieve success more quickly by deliberately making errors than by considering only data that support the assumption. Moreover, executives who apply a conventional, systematic approach to solving a pattern recognition problem are often slower to find a solution than those who test their assumptions by knowingly making mistakes. How do you distinguish between smart mistakes and dumb ones? The authors' consulting firm has developed, and currently uses, a five-step process for identifying constructive mistakes. In one test, the firm assumed that a mistake it was planning to make would cost a significant amount of money, but the opposite happened. By turning assumptions on their heads, the firm created more than dollar 1 million in new business.  相似文献

In this paper, competence is defined in operational terms as the degree to which the firm or its subunits can reliably meet or exceed objectives. Two antecedents to competence (and thus competitive advantage) are then developed and defined. These are the ‘comprehension’ of the management team working on developing competence and the ‘deftness’ of their task execution. Empirical results from a study of 160 new initiatives in 40 organizations from 16 countries suggest that: (1) it is feasible to operationalize and measure these constructs; (2) comprehension and deftness are important correlates of an organization's degree of competence as defined; and (3) a process-centered paradigm for understanding competence development shows promise.  相似文献
