This study investigates the presentations of Hiroshima and Nagasaki as postwar tourism destinations in a selection of Japanese-language guidebooks. Comparison is made between commonly voiced criticisms of Japanese attitudes toward the two atom-bombed sites and the tourism activities suggested by the publications themselves. An expected presentation emphasizing Japanese suffering as a result of the atom bombs is not found in the guides, but neither is an openness to discussion of the war. The conclusions reached find Hiroshima standing as emblematic of the rebuilding nation as a whole, while Nagasaki remains largely outside of the social and cultural dynamics of postwar Japan.  相似文献

Mortgage-prepayment risk underlies the structuring of mortgage-backed derivative securities, such as tranched real estate mortgage investment conduits. This prepayment comes either from mortgage termination or from curtailment, where the borrower retains the existing mortgage and prepays a portion. There are differences in cash flows from the two types of prepayment. In termination, the loan disappears from a pool, and the scheduled payment to investors in the pool is reduced. In curtailment, the loan survives, and the scheduled payment is unchanged but the term is reduced. There are implications for structuring mortgages and derivative securities. The prepayment decision is embedded in an in-tertemporal household utility maximization framework where choices are made between refinancing, making the regular payment, default or curtailment. Empirical results are presented for Government National Mortgage Association (GNMA) pools, and an algorithm is presented that separates the termination and curtailment components, facilitating the development of derivative securities.  相似文献

Zusammenfassung Die Wirkung von ausl?ndischer Kapitalbeteiligung und Kreditfinanzierung auf Ersparnisbildung und Wachstum in Entwicklungsl?ndern. — Zur Bew?ltigung der internationalen Schuldenprobleme von Entwicklungsl?ndern wird h?ufig vorgeschlagen, die Struktur des Kapitalimports zugunsten von Forderungsarten zu verschieben, bei denen sich die Gl?ubiger am wirtschaftlichen Risiko beteiligen, wie dies etwa bei Direktinvestitionen der Fall ist. Die Wahl zwischen Kapitalbeteiligung und Kreditfinanzierung mag jedoch Risiko-Ertrag-Konflikte zwischen Einkommensstabilit?t und erwartetem wirtschaftlichem Wachstum involvieren. Diese Hypothese wird aus einem entscheidungstheoretischen Modell auf der Basis eines Benutzer-Eigentümer Verh?ltnisses abgeleitet und mittels einer L?nderquerschnittsuntersuchung regressionsanalytisch getestet. Es zeigt sich, da\ bei nichtkooperativen Beziehungen zwischen Schuldnern und Gl?ubigern kreditfinanzierte Kapitalimporte einen vergleichsweise starken positiven Einflu\ auf die Ersparnisbildung und das Wirtschaftswachtum im Schuldnerland ausüben. Kapitalbeteiligungen k?nnen deshalb nicht ohne weiteres als vorteilhaft angesehen werden und auch nicht allen L?ndern empfohlen werden, ohne zu bedenken, wie sich soziale Gruppen gegenüber dem Risiko verhalten.
Résumé Les effets de l’influx de la dette et du capital propre sur l’épargne et la croissance en économies développantes. — L’élément commun des beaucoup de propositions données pour faciliter les problèmes de la dette extérieure des pays développants est l’intention de changer la structure des importations de capital vers l’augmentation du rapport des créances qui basent sur quelque forme de partager les risques, p.e. la participation en capital propre. Cependant, le choix entre le capital propre ou des influx des capitaux financés par des dettes peut induire un conflit de ?rendement-risque? entre la stabilité de revenu et la croissance attendue. Cette hypothèse est dérivée d’un modèle choix-théorique basé sur l’approche agent-principal et testée empiriquement en appliquant l’analyse de régression trans-pays. Les auteurs démontrent que, dans un cadre non-coopératif des relations débiteurcréditeur, des transferts financés par des dettes ont une influence plus positive sur l’épargne et la croissance économique. La participation en capital propre ne peut pas être évaluée supérieure sans ambigu?té et c’est pourquoi elle ne peut pas être recommendée pour tous les pays, indépendant des attitudes sociales envers le risque.

Resumen El efecto del endeudamiento sobre el ahorro y el crecimiento eneconomías en desarrollo comparado con el de las inversiones directas. — En varias propuestas para aliviar el problema de la deuda externa de los países en desarrollo se sugiere alterar la composición de las importaciones de capital en el sentido de aumentar la proportión de derechos con participación en el riesgo económico, es decir, la participación de la inversión directa. La elección entre inversión directa y deuda considera la relación inversa riesgo-beneficio que existe entre la estabilidad del ingreso y el crecimiento esperado. Esta tesis se dériva de un modelo teórico de elección basado en el enfoque agente-principal, que es sometido a un test empírico de regresión sobre una muestra de países. Se muestra que en el marco de relaciones deudor-acreedor de tipo no cooperativas las transferencias de financiamiento por deuda ejercen una influencia positiva relativamente superior sobre el ahorro y el crecimiento económico. La participación directa en el capital no resulta superior en todos casos y por ello no puede ser recomendada para todos los países, independientemente de las actitudes frente al riesgo que prevalezcan.

The directive on insurance mediation, proposed by the European Commission, is supposed to secure a minimum standard of professional competence for intermediaries to protect customers as well as to ascertain the intermediaries’ freedom of establishment and freedom to provide services in the internal market. Pursuant to the directive, only an intermediary who is registered in his / her home country’s intermediary register will be allowed to mediate insurances. The intermediary has to comply with professional requirements set by the directive in order to be registered. Yet, part-time intermediaries can be exempted from those requirements by the member states. Additionally, the intermediaries are burdened with certain information and documentation duties towards their customers, a breach of which will cause personal liability. Only these contractual duties are to be implemented in the WG (German Insurance Act), which is soon to be basically reformed.  相似文献

Interactive television has arrived, thanks to substantial technology investments that have been made by Sky and others. It is growing in importance as innovative interactive applications are developed for broadcast programmes (eg the BBCi service and Big Brother), and for advertising — and will develop further when broadband deployment gets to critical mass. Readers should not expect a television-variant of the world wide web, however. This was tried during 2000–2002 in the form of web look-alike, interactive ‘walled garden’ sites, and failed to attract critical mass footfall. The model has evolved and now revolves around interactive content synchronised with broadcast, which offers financial services companies an interesting new way to increase awareness and to differentiate the service presentation. Furthermore, over the next ten years, broadband is expected to usher in a new era of personalised television — in which specialised broadcasts (such as personal pensions advice programmes) can be made available on demand. The observations in this paper are mainly drawn from the UK, where digital television penetration is high; the lessons can be applied more broadly, however, and are relevant to any organisation thinking of promoting its service through entertainment channels.  相似文献

Backtesting Value-at-Risk: A Duration-Based Approach   总被引:2,自引:0,他引:2  
Financial risk model evaluation or backtesting is a key partof the internal model's approach to market risk management aslaid out by the Basle Committee on Banking Supervision. However,existing backtesting methods have relatively low power in realisticsmall sample settings. Our contribution is the exploration ofnew tools for backtesting based on the duration of days betweenthe violations of the Value-at-Risk. Our Monte Carlo resultsshow that in realistic situations, the new duration-based testshave considerably better power properties than the previouslysuggested tests.  相似文献

UNEMPLOYMENT, HYSTERESIS AND TRANSITION   总被引:3,自引:0,他引:3  
In this paper, we quantify the degree of persistence in the unemployment rates of transition countries using a variety of methods benchmarked against the EU. Initially, we work with the concept of linear ‘Hysteresis’ as described by the presence of unit roots in unemployment as in most empirical research on this area. Given that this is potentially a narrow definition, we also take into account the existence of structural breaks and nonlinear dynamics in unemployment. Finally, we examine whether CEECs' unemployment presents features of multiple equilibria, that is, if it remains locked into a new level whenever some structural change or sufficiently large shock occurs. Our findings show that, in general, we can reject the unit‐root hypothesis after controlling for structural changes and business‐cycle effects, but we can observe the presence of a high and low unemployment equilibria. The speed of adjustment is faster for CEECs than the EU, although CEECs tend to move more frequently between equilibria.  相似文献
