In this paper, we study the relationships among financial market sub-segments as a way to identify potential financial distress through increased co-movements among them. To study how sub-markets are mutually co-dependent, we combine granular data on over-the-counter derivatives by trade repositories and the joint probability of distress (JPoD) approach introduced by the International Monetary Fund. We define an indicator that combines several distress drivers and observe that results on co-dependencies are similar to those that would be expected: similarities between financial and contractual terms seem to be responsible for stronger co-movements among sub-markets. However, high values for JPoD even in correspondence of quite dissimilar sub-markets suggest the presence of other drivers that should be investigated in future research. To the best of our knowledge, this is the first empirical study on systemic risk assessment based on micro-founded trade repositories’ data on interest rate swaps.  相似文献

In this paper we consider the problem of hedging an arithmetic Asian option with discrete monitoring in an exponential Lévy model by deriving backward recursive integrals for the price sensitivities of the option. The procedure is applied to the analysis of the performance of the delta and delta–gamma hedges in an incomplete market; particular attention is paid to the hedging error and the impact of model error on the quality of the chosen hedging strategy. The numerical analysis shows the impact of jump risk on the hedging error of the option position, and the importance of including traded options in the hedging portfolio for the reduction of this risk.  相似文献

We use stock market data to analyze the quality of alternative models and procedures for forecasting expected shortfall (ES) at different significance levels. We compute ES forecasts from conditional models applied to the full distribution of returns as well as from models that focus on tail events using extreme value theory (EVT). We also apply the semiparametric filtered historical simulation (FHS) approach to ES forecasting to obtain 10-day ES forecasts. At the 10-day horizon we combine FHS with EVT. The performance of the different models is assessed using six different ES backtests recently proposed in the literature. Our results suggest that conditional EVT-based models produce more accurate 1-day and 10-day ES forecasts than do non-EVT based models. Under either approach, asymmetric probability distributions for return innovations tend to produce better forecasts. Incorporating EVT in parametric or semiparametric approaches also improves ES forecasting performance. These qualitative results are also valid for the recent crisis period, even though all models then underestimate the level of risk. FHS narrows the range of numerical forecasts obtained from alternative models, thereby reducing model risk. Combining EVT and FHS seems to be best approach for obtaining accurate ES forecasts.  相似文献

Relational exchange arrangements supported by trust are commonly viewed as substitutes for complex contracts in interorganizational exchanges. Many argue that formal contracts actually undermine trust and thereby encourage the opportunistic behavior they are designed to discourage. In this paper, we develop and test an alternative perspective: that formal contracts and relational governance function as complements. Using data from a sample of information service exchanges, we find empirical support for this proposition of complementarity. Managers appear to couple their increasingly customized contracts with high levels of relational governance (and vice versa). Moreover, this interdependence underlies their ability to generate improvements in exchange performance. Our results concerning the determinants of these governance choices show their distinct origins, which further augments their complementarity in practice.

Consumers’ perception of, and satisfaction with, fruit quality is an important issue for both public policy and commercial reasons. However, because of information problems, consumers cannot easily choose fruits of a quality most likely to satisfy their preferences and health needs. The research reported here employed an experimental auction method to test perceptions of fruit quality by evaluating the willingness to pay (WTP) of consumers for five different varieties of soft citrus under three different information conditions: visual inspection of the fruit before peeling; visual inspection after peeling; and after consumption. Significant differences were found in valuations of the different varieties as consumers gained information. Conclusions are drawn about the value of the methodology and the results themselves, and implications are inferred for policy and for growers and traders. It is argued that product information should be oriented not just towards nutritional education but also towards increasing the pleasure of healthy eating.  相似文献

Two goals of food assistance programs are to improve well-being and to increase participation among those in need. Progress in meeting the first goal can be measured by the difference in well-being between participants and eligible non-participants. This gap in well-being though can be affected by progress made toward the second goal of increasing participation rates. In particular, if those with the lowest levels of well-being disproportionately enter the program, the gap can increase. To examine whether this tension between goals exists empirically, we consider the case of the Food Stamp Program and its effect on food insecurity in the United States, using data from the Survey of Income and Program Participation (SIPP). In particular, we use variation in State policies (the change in administrative error rates and the combined value of Temporary Assistance for Needy Families (TANF) and food stamp benefits) to analyze whether increasing participation rates leads to increases in the difference in food insecurity rates. Controlling for other factors, we find evidence of the tension between these two program goals insofar as States with policies which encourage participation have higher differences in the food insecurity rates of participants and non-participants.  相似文献

Nursing leaders in ambulatory care need to objectively quantify patient intensity to balance patient care needs and nursing resources. In this three-part series, current literature on acuity/intensity tools will be reviewed, and the development of an Ambulatory Intensity System (AIS) to objectively quantify nursing care will be described. In this article, the ongoing implementation of the system, its incorporation into the organization's established computerized appointment system, reliability measures, and related performance improvement activities will be discussed.  相似文献
