热钱与金融稳定

热钱总是偏爱快速经济增长的新兴市场国家。我国自然是热钱流入的热土。热钱的流入必然导致国内资产价格的大幅度波动,造成金融市场的不稳定。为此,短期内加强对资本流动的监管,有效地阻止热钱的流入,长期内建立金融稳定监控和预警系统。

Credit lender–borrower relationship in the credit card market – Implications for credit risk management strategy and relationship marketing

Lehman Brothers filed for bankruptcy in 2008, precipitating the international financial crisis. Many questioned the banks’ risk-taking credit system. Understanding credit risk and how the credit system functions may provide knowledge on managing credit, to avoid another such international crisis. We study the credit card field and present a pricing decision model for managing credit risk. Recent credit lenders’ portfolio re-pricing practices call for immediate attention to the credit lender–borrower relationship and relationship marketing. A literature review and recent phenomena in the credit card industry reveal that the lenders’ re-pricing strategy negatively affects the credit lender–borrower relationship and relationship marketing. Thus, we introduce a pricing decision model incorporating the lenders’ re-pricing strategy and the credit lender–borrower relationship. Further, we discuss the implications of, and the role of marketing in, credit risk management and the implications of relationship marketing for credit lenders in foreign markets, including the US market.     

A Critical Assessment of Basel III and its Implications on the Mauritian Banking Sector

This paper probes into the application of Basel III in Mauritius. Findings show that although Mauritian banks are well-capitalized and carry excess liquidity, they will have to restructure their balance sheets by incorporating highly liquid assets such as government securities. While Basel III will foster greater financial stability, this will translate into lower supply of credit, higher cost of credit and lower returns with potential strains on SME lending. Similarly, Bank of Mauritius’s ability to control credit growth will be hindered because banks’ existing leverage ratios are already higher than the stipulated minimum leverage ratio of 3%. To harness the full benefits of the reforms, additional measures tailored to the specificities of the Mauritian economy will be needed. Other challenges prevail like establishing robust data management, risk methodologies, reporting systems and IT architecture as well as identifying the timing and the size of the Countercyclical Capital Buffer. Local banks anticipate Basel IV in the coming years as a refined tool.

Exchange rate versus inflation targeting: a theory of output fluctuations in traded and non-traded sectors

This paper develops a basic model for output fluctuations in traded and non-traded sectors under two alternative monetary policy regimes; exchange rate targeting (or monetary union) and inflation targeting. The conventional wisdom from one-sector models says that inflation targeting gives better output stabilization than exchange rate targeting when demand shocks occur, but the opposite when supply shocks occur. In a model with a traded and a non-traded sector, we show that the conventional wisdom holds for the non-traded sector. However, for the traded sector, we show that inflation targeting destabilizes output compared with exchange rate targeting when both supply and demand shocks occur. The only shocks where inflation targeting provides the better output stability for the traded sector are shocks to world market prices. The two-sector structure introduces new mechanisms that may turn around earlier results for aggregate production. For instance, a demand shock may induce higher aggregate output fluctuations with inflation targeting than with exchange rate targeting. Furthermore, a positive demand shock may prove to be contractionary under inflation targeting.     

Does scoring a subpopulation make a difference

Scorecards used by consumer credit providers to assess the probability that an applicant will default are usually built for the population of potential applicants as a whole. This paper investigates whether it is permissible and worth-while to build a separate scorecard for each subpopulation of applicants. We review the legal requirements to find that it is permissible to use separate scorecards for many, but not all, personal characteristics. Second, using data supplied by a credit card organization separate scorecards were built for several subpopulations for each of twelve personal characteristics. The predicted performance of each was compared with that gained form estimating a scorecard for the full population using three methods for setting the cut-off scores in an `independent' way. These methods differ in the degree to which the cut-off scores are independent of information about other subpopulation, in the level of discrimination achieved between likely good payers and defaulters and in the degree to which each method is robust to new data. We conclude, first, that creating scorecards using subpopulations does not necessarily give better discrimination between likely good payers and defaulters. Second, none of the three methods examined to set the cut-off scores dominates the others using the three desirable properties described; trade-offs are required. Finally, subpopulation scorecards lead to the rejection of fewer applicants than scorecards built on full populations.
