In particular, we estimate a model on the EONIA spread since the introduction of the new operational framework in March 2004 until August 2006. We show that the increase in the EONIA spread can for the largest part be explained by the current liquidity deficit. Moreover, tight liquidity conditions as well as an increase in banks’ liquidity uncertainty lead to a significant upward pressure on the spread. The ECB’s liquidity policy only reduces the spread if a loose policy is conducted during the last week of a maintenance period. Interestingly, interest rate expectations have not been found to have an important influence.

Emerging retail payments are prone to operational and fraud risks, especially security breaches and potential use in illicit transactions. This article describes an economic framework for understanding risk control in retail payments. Risk control is a special type of good because it can protect one payment participant without diminishing the protection of other participants. As a result, the authors' economic framework emphasizes risk containment, primarily through the establishment and enforcement of risk management policies. Application of the framework to three types of emerging payments suggests that a payments system can successfully manage risk if it quickly recognizes problems, encourages commitment from all participants to control risk, and uses an appropriate mix of market and public policy mechanisms to align risk management incentives. The authors conclude that providers of emerging payment methods must mitigate risk effectively or face rejection in the payment market.","PeriodicalId":170505,"journal":{"name":"Macroeconomics eJournal","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115114051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the macroeconomic scenarios satisfying some plausibility constraint we determine the worst case scenario which causes the most harmful loss in loan portfolios. This method has three advantages over traditional macro stress testing: First, it ensures that no harmful scenarios are missed and therefore prevents a false illusion of safety which may result when considering only standard stress scenarios. Second, it does not analyse scenarios which are too implausible and would therefore jeopardize the credibility of stress analysis. Third, it allows for a portfolio specific identification of key risk factors. Another lesson from this paper relates to the use of partial stress scenarios specifying the values of some but not all risk factors: The plausibility of partial scenarios is maximised if we set the remaining risk factors to their conditional expected values.","PeriodicalId":170505,"journal":{"name":"Macroeconomics eJournal","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114626191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Labor income seems like a \"money market mutual fund\" whose balance in one or two years is predictable but a wide dispersion results after many years, reflecting fluctuations in economic conditions. We use the Martingale method to derive an analytical solution, finding that Merton's well-known \" constant-mix strategy\" is still true after incorporating human capital from the perspective of \"total wealth\" management. Moreover, the proportion in risky assets implicit in the agent's human capital is the main factor determining the optimal investment strategy. The numerical examples suggest that young investors should short stocks because their human capital has large market exposure. As they age, however, their human capital becomes \"bond-like\", and thus they have to hold stocks to achieve optimal overall risk exposure.","PeriodicalId":170505,"journal":{"name":"Macroeconomics eJournal","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123925120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on a large dataset of countries from Standard and Poor's and Moody's, we find strong statistical evidence of a large ratings premium-nearly two notches-for those oil-producing countries with a large share of net oil revenue to gross domestic product, relative to countries with similar economic fundamentals. We have some limited forecast information from the rating agencies and the effect increases when we include this information, providing further evidence that this ratings premium is not driven by expected improvements in fundamentals. This finding has significant implications for asset prices in oil-producing countries and highlights the risk that in the event of a sharp unanticipated drop in oil prices, sovereign rating downgrades of oil-producing countries could be sharper than the deterioration in their economic fundamentals.","PeriodicalId":170505,"journal":{"name":"Macroeconomics eJournal","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121910448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exchange Rate Regimes and Capital Mobility: How Much of the Swoboda Thesis Survives? 汇率制度与资本流动:斯沃博达理论还能站得住多少?

This paper takes another look at the evidence for this hypothesis using two popular de facto classifications of exchange rate regimes. That evidence supports the bipolar view for the advanced countries, the sample for which it was originally developed, but not obviously for emerging markets and other developing countries. One interpretation of the contrast is that there is a tendency to move away from intermediate regimes in the course of economic and financial development, implying that emerging markets and other developing countries will eventually abandon intermediate regimes as well. Another interpretation is that the advanced countries have been faster to abandon soft pegs because they have been faster to develop attractive alternatives, notably Europe's monetary union. In this view, other countries are unlikely to abandon soft pegs because of the absence of the distinctive political conditions that have made the European alternative feasible. A final interpretation is that the advanced countries have been able to abandon soft peg because of their success in substituting inflation targeting for exchange rate targeting as the anchor for monetary policy. The paper presents some evidence for this view, which suggests the feasibility of further movement by emerging markets and developing countries in the direct of greater exchange rate flexibility.","PeriodicalId":170505,"journal":{"name":"Macroeconomics eJournal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129154118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
