Capital efficiency and asset/liability management are part of the Enterprise Risk Management Process of any insurance/reinsurance conglomerate and serve as quantitative methods to fulfill the strategic planning within an insurance organization. A considerable amount of work has been done in this ample research field, but invariably one of the last questions is whether or not, numerically, the method is practically implementable, which is our main interest. The numerical issues are dependent on the traits of the optimization problem, and therefore we plan to focus on the optimal reinsurance design, which has been a very dynamic topic in the last decade. The existing literature is focused on finding closed-form solutions that are usually possible when economic, solvency, and other constraints are not included in the model. Including these constraints, the optimal contract can be found only numerically. The efficiency of these methods is extremely good for some well-behaved convex problems, such as Second-Order Conic Problems. Specific numerical solutions are provided to better explain the advantages of appropriate numerical optimization methods chosen to solve various risk transfer problems. The stability issues are also investigated together with a case study performed for an insurance group that aims capital efficiency across the entire organization. 相似文献

Wage arrears are widespread in Russia, and are one of the main causes of uncertainty in the labour market. In this paper, we use the Russian Longitudinal Monitoring Survey over the period 1994–98 to construct a new and improved measure of household income risk, based on the uncertainty due to wage arrears. We then use this measure of uncertainty to test the precautionary saving hypothesis, according to which households save to self‐insure against risk. We find significant evidence of additional saving by those households whose head is more likely to suffer from wage arrears one year hence. This suggests the existence of a strong precautionary saving motive. 相似文献

We investigate stock market rationality by examining the timeliness and unbiasedness of the market's response to dividend announcements. Our initial findings for market timeliness show a sluggish market reaction to dividend announcements; however, when the ex-dividend effect is controlled for, we find no evidence of a sluggish market reaction. We examine the unbiasedness of the market's response by testing whether the net announcement effect across a sample that is devoid of ex-post selection bias sums to zero. We observe a significant positive net announcement effect and examine several plausible conjectures for this puzzling phenomenon, but none provides a satisfactory explanation. 相似文献

This research attempts to analyze economic effects of spatial integration of urban water service markets in Korea, employing the notion of economies of scale in terms of cost-effectiveness. The economies of scale are measured by the elasticity of supply with respect to the production cost from the translog cost function of urban water supply enterprises. It was found that the economies of scale in most urban water utility firms of Seoul Metropolitan region have continuously increased during the period 1989–1994. While the economies of scale would be hardly influenced by the changes in population density, they would tend to decrease marginally in response to the rise in employment density. If the urban water markets of the Seoul Metropolitan Region were consolidated into a single water service market without any changes to the current spatial network of water supply and regional economic attributes, the production cost would be reduced up to 47.1 percent of the actual cost in 1994. Those savings would be enough to make up for the financial deficit of the water production of the Seoul Metropolitan Region. 相似文献

Several principles of international bank regulatory jurisdictions have emerged since the mid-1970s. Each principle has advantages and disadvantages in promoting cross-border competition, ensuring prudent banking practice, and maintaining worldwide financial stability. At the same time, simultaneous application of different principles by different countries has caused overlapping, underlapping, or sheer avoidance of bank regulations, resulting in less transparency and an uneven playing field for internationally competing banks. To level the playing field, bank regulatory harmonization has been advocated, particularly under the auspices of the Basle Committee on Banking Supervision. However, as demonstrated in the case of setting minimum capital standards for market risks, a successive harmonization approach may not be the panacea. There is a need for rethinking of efficiency in regulation, including incentive-compatible approaches. 相似文献

This paper shows that it is not always correct to make an upward adjustment to the stock beta in calculating the hurdle rate for capital budgeting even when the project under consideration is riskier than existing assets. The paper also shows that the correct hurdle rate is smaller than the market capitalization rate calculated from the firm's stock beta when the project under consideration has the same risk as existing assets. In addition, it is shown that the market capitalization rate will be an underestimate (overestimate) of the correct hurdle rate when the risk of future assets is greater (smaller) than both the risk of assets in place and that of future capital expenditures. These new results are direct consequences of the insight that the firm's investment opportunities are in fact real call options written on underlying assets. 相似文献

Repudiations rarely occur due to their extreme nature. This paper provides an empirical study based on an original database: prices of a Tsarist bond traded in Paris before and after its repudiation by the Soviets. A structural VAR is used to disentangle French market shocks from repudiation specific ones. After the repudiation, we identify shocks that are related with bailouts, hopes of partial bailouts, negotiations with the Soviets and the Russian civil war. We argue that bond prices essentially reflected expected extreme events that never took place and were thus subject to a “Peso problem”.The authors thank Howard Bodenhorn, Michael Bordo, Frans Buelens, Ariane Chapelle, André Farber, Georges Gallais-Hamonno, Jean-Jacques Heirwegh, Marie-Paule Laurent, Larry Neal, Hugh Rockoff, Ariane Szafarz, Gail Triner, Andrey Ukhov, Loredana Ureche-Rangau, Daniel Waldenstr?m, Marc Weidenmier, Eugene White as well as the editor, William Goetzmann, an anonymous referee, the participants of the 2005 BETA workshop in historical economics and of the 2005 European Historical Economics Society Annual Conference for helpful comments.
