This paper examines the effect of heterogeneity in clearing members’ exposure management practices under central clearing. Our network model specifies the dynamics of prenetted interbank exposures to shape interdependent exposure distributions beyond normality. Employing over-the-counter derivatives market data from the U.S. Office of the Comptroller of the Currency, our simulation results indicate that heterogeneity in bank-to-bank exposure dynamics is systemically desirable, while the entire system benefits more from the central clearing in more homogeneous environments. Policymakers should incentivize individual clearing members to enhance resiliency and stability in counterparty exposure management to maximize netting efficiency under central clearing. 相似文献

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services. 相似文献

Using data on job approval ratings of governors, U.S. senators, and the president, we find that firms located in states with high approval ratings outperform firms located in states with low approval ratings by .64% per month. Furthermore, this relationship is stronger when investors are actively involved in politics, when local politicians are closer to the center of political power, for small firms that have a larger proportion of local investors, and for financially strong areas where investors are ready to execute investments in local stocks. Overall, our study shows that investors’ political sentiment is important in determining stock returns. 相似文献

Terms, such as “out-of-stock,” “sold out,” and “unavailable” are commonly used by retailers to communicate a product or brand outage. Although these terms are technically equivalent, prior research on product outage and product scarcity suggest that they may be interpreted and processed differently by consumers. The present research investigated whether the manner in which a product outage was framed elicited different consumer behavioral intentions, attributions, and perceptions in the context of online retailing. Data were collected by means of an online experiment. The experiment incorporated a hypothetical scenario approach in which research participants were asked to react to a particular combination of treatment and blocking factors. Results demonstrated that ceteris paribus, framing a product or brand outage as “sold out” produces fewer negative product and website reactions than does framing it as “out-of-stock” or “unavailable.” 相似文献

This paper studies the problem of an uninformed decision maker who acquires expert advice prior to making a decision. I show that it is less costly to hire partisan agents than impartial agents, especially under advocacy, and that the decision maker prefers partisan advocacy to other forms of institutions. I also extend the literature, originating with Dewatripont and Tirole ( 1999 ), to a setting with contracts that condition on information provided and not just the decision made. 相似文献

We perform event analysis on particular episodes of tension in the Korean peninsula between 2000 and 2008, and investigate the effect of the events on South Korean financial markets (stock markets, bond yield spreads and the exchange rate) given that South Korea would be the first affected by a military aggression from North Korea. Surprisingly, in nearly all cases, these events, which have often been dramatized in the world media, have no significant impact on either of these variables or only a very small one. We also find no significant impact of events on listed firms that would a priori be likely to suffer from increased tension between the two Koreas. Since financial markets often contain better predictions than expert opinions or surveys, these results strongly suggest that the North Korean threat is non‐credible. 相似文献

Using data on corporate default experience in the U.S. and market rates of CDX index and tranche swaps of various maturities, we estimate reduced-form models of correlated default timing in the CDX High Yield and Investment Grade portfolios under actual and risk-neutral probabilities. The striking contrast between the estimated processes followed by the actual and risk-neutral arrival intensities of defaults, and between the parameters governing the actual and risk-neutral dynamics of the risk-neutral intensities, indicates the presence of substantial default risk premia in CDX swap market rates. The effects of risk premia on swap rates covary strongly across maturities, and depend on general stock market volatility and several measures of credit spreads. Large moves in the effects of these premia on swap rates have natural interpretations in terms of economic and financial market developments during the sample period, April 2004 to October 2007. Our results suggest that a large portion of the movements in CDX swap market rates observed during the sample period may be caused by changing attitudes toward correlated default risk rather than changes in the economic factors affecting the actual risk of clustered defaults, which ultimately governs swap payoffs. 相似文献

This research examines the effects of impression management on consumers’ coupon redemption and suggests different underlying mechanisms with respect to cultural self‐construal. Four studies show that, when primed with impression management, individualistic (vs. collectivistic) consumers are more likely to redeem coupons, because individualists believe that coupon redemption creates the impression of being smart. On the other hand, collectivistic consumers are less likely to redeem coupons when coupon usage is visible to others, because they believe that coupon redemption gives the impression of being cheap. These findings are explained within the context of cultural self‐construal and regulatory focus theory. 相似文献
