Backbone of credit relationships in the Japanese credit market

We detect the backbone of the weighted bipartite network of the Japanese credit market relationships. The backbone is detected by adapting a general method used in the investigation of weighted networks. With this approach we detect a backbone that is statistically validated against a null hypothesis of uniform diversification of loans for banks and firms. Our investigation is done year by year and it covers more than thirty years during the period from 1980 to 2011. We relate some of our findings with economic events that have characterized the Japanese credit market during the last years. The study of the time evolution of the backbone allows us to detect changes occurred in network size, fraction of credit explained, and attributes characterizing the banks and the firms present in the backbone.Comment: 14 pages, 8 figure

Mergers in Emerging Markets with Network Externalities: The Case of Telecoms

This paper develops a unifying framework to understand competition issues in networkindustries. It focuses on the telecom(munication) industry and takes two specific effectsof this industry into account. First, the telecom industry is in continuous evolution andalliances affect not only the current market power of the firms but also the evolution ofthe industry. Second, the production of services in the industry is evolving towards theprovision of integrated services in a "system" that benefits from strong "networkexternalities". The analysis suggests that the antitrust authorities should capture as wellsuch effects as the magnitude of the installed bases, the compatibility of the alliance’ssystem with other systems, the switching costs for customers and application writers,and the "credibility" of the alliance to offer the service. The developed frameworkbuilds on the existing models of networks and combines the different network effects. The relevance of the framework is shown for two important merger cases (WorldCom-MCI and MSG cases), involving respectively an existing market and an emerging one.

An Analysis of the Japanese Credit Network

An analysis of the Japanese credit market in 2004 between banks and quoted firms is done in this paper using the tools of the networks theory. It can be pointed out that: (i) a backbone of the credit channel emerges, where some links play a crucial role; (ii) big banks privilege long-term contracts; the "minimal spanning trees" (iii) disclose a highly hierarchical backbone, where the central positions are occupied by the largest banks, and emphasize (iv) a strong geographical characterization, while (v) the clusters of firms do not have specific common properties. Moreover, (vi) while larger firms have multiple lending in large, (vii) the demand for credit (long vs. short term debt and multi-credit lines) of firms with similar sizes is very heterogeneous.Comment: 23 pages with 14 figures; revised and Figure 14 adde

Export-Led Industrialisation and Growth - Korea's Economic Miracle 1962-89

The period 1962-89 witnessed a remarkable transformation of the South Korean economy, from being poverty ridden to the attainment of the status of newly industrialised nation. This transformation was achieved through the adoption of an outward oriented industry led strategy, based, particularly during the period of the 1970s, upon the development of large-scale industrial conglomerates and the attainment of economies of scale and technology to achieve international competitiveness. By the early 1980s this strategy had resulted in major structural imbalances, a weakened financial section, heavy concentration in domestic markets, and a repressed development of small and medium enterprises. By the end of the 1980s, despite attempts at economic reform during this decade, the structural and financial problems remained which were to prove the country’s undoing during the financial and economic crisis of 1997-98. This issue of whether Korea’s performance during this period can be described as an economic miracle is also reviewed. The empirical evidence on this issue is mixed and no conclusive evidence can be drawn. However, despite this, the achievements of the Korean economy during the period under discussion should not be underestimated.TRIPS, legitimacy, World Trade Organization

Lending relationships and credit rationing: the impact of securitization

Do lending relationships mitigate credit rationing? Does securitization influence the impact of lending relationships on credit rationing? If so, is its impact differently in normal periods versus crisis periods? This paper combines several unique data sets to address these questions. Employing a disequilibrium model to identify credit rationing, we find that more intense lending relationships, measured through their length and lower number, considerable improve credit supply and reduce the degree of credit rationing. In general, we find that a relationship with a bank that is more involved in securitization activities relaxes credit constraints in normal periods; however, it also increases credit rationing during crisis periods. Finally, we study the impact of different types of securitization – covered bonds and mortgage-backed securities (MBS) – on credit rationing. While both types of securitization reduce credit rationing in normal periods, the issuance of MBS by a firm’s main bank aggravates these firm’s credit rationing in crisis periods.lending relationships;financial crisis;securitization

Corporate governance, moral hazard and conflict of interest in Italian universal banking, 1914-1933

Universal banking is widely held to enjoy comparative advantages in corporate finance. Recent theories of financial intermediation argue that 'insider systems' are better suited to effectively deal with long-term growth and moral hazard problems. However, little attention (if any) is usually paid to corporate governance problems that are specific to universal banking. How can banks' ownership structure and agency problems influence their ability to address longterm growth and moral hazard problems? Under which institutional arrangements, incentives and constraints can universal banking effectively realize its potential? The paper looks at such issues through the experience of interwar Italy. The evolution of universal banking in the 1920s emerges as heavily exposed to potentially serious problems of moral hazard and conflicts of interest, due to inefficient corporate governance, lack of external controls and a moral-hazard-enhancing institutional set-up. These factors may distort bank managers' incentives, affect strategic trade-offs and lead to unsound banking. The findings are consistent with that part of corporate governance literature which points to the potential for moral hazard and conflicts of interest inherent to universal banking and emphasise the conditional and historically-specific nature of its alleged benefits
