We estimate a dynamic network (DN) directional output distance function for 100 Japanese banks operating during 2007–2012. Network production occurs in that deposits and other funds raised are produced as intermediate products in stage 1 and those intermediate products are used to generate a portfolio of assets in stage 2. The dynamic technology links production periods via nonperforming loans (NPL) and carryover assets, which take the form of excess reserves. Carryover assets expand the future production possibility set while NPL shrink future production possibilities. We extend previous DN methods to measure the performance of three types of Japanese commercial banks: city banks, regional banks and second regional banks. We test for and find differences in the three bank technologies relative to a common technology. Such differences are likely due to different institutional and regulatory structures. Unlike previous DN studies, we also allow for a non‐uniform abatement factor between previously‐produced NPL and other inputs in stage 1 and between performing loans and NPL in the current period. Measured productivity change is greater when each bank faces their own group technology rather than the pooled technology consisting of all bank types. 相似文献

This article examines trends in relative wages between high- and medium-skilled workers and between medium- and low-skilled workers in Finland, Germany, Italy, South Korea and the US over the period 1970–2005. It is found that there are large differences in the evolution wage inequality across the countries in our sample, with some countries showing a long-run upward trend in relative wages (such as the US, Germany and Italy) and others showing a long-run downward trend (such as Finland and Korea). The main conclusion from our results is that inequality is not an inevitable by-product of technological change. 相似文献

In a market where sellers compete by posting trading mechanisms, we allow for a general search technology and show that its features crucially affect the equilibrium mechanism. Price posting prevails when meetings are rival, i.e., when a meeting by one buyer reduces another buyer's meeting probability. Under price posting buyers reveal their type by sorting ex-ante. Only if the meeting technology is sufficiently non-rival, price posting is not an equilibrium. Multiple buyer types then visit the same sellers who screen ex-post through auctions. 相似文献

Ad valorem versus unit taxes: monopolistic competition, heterogeneous firms, and intra-industry reallocations 总被引:1,自引:1,他引:0
Real-world industries are composed from heterogeneous firms and substantial intra-industry reallocations take place, i.e.
high productivity firms squeeze out low productivity firms. Previous tax-tool comparisons have not included these central
forces of industry structure. This paper examines a general equilibrium monopolistic competition model with heterogeneous
firms and intra-industry reallocations. We show that the welfare superiority of ad valorem over unit taxes under imperfect
competition is not only preserved but amplified. The additional difference between the tools arises because unit taxes distort
relative prices, which in turn reduces average industry productivity through reallocations (the survival and increased market
share of lower productivity firms). Importantly, numerical solutions of the model reveal that the relative welfare loss from
using the unit tax increases dramatically in the degree of firm heterogeneity. 相似文献

AbstractNational parks in Canada operate under the dual mandate of conservation and visitor use, which involves balancing ecological integrity and nature-based tourism activities. Climate-induced environmental change may increase the existing tension between conservation and visitor use as major tourism resources located in protected areas (PAs) are projected to undergo large-scale changes. This study draws upon the behavioural approach, scenario planning, and landscape visualizations to examine the relationship between climate change impacts, visitor perceptions, and visitor experience management at the Athabasca Glacier in Jasper National Park, Canada. Four tourism development scenarios defined by two management drivers (ecological integrity and visitor demand) with corresponding storylines and visualizations were developed for 2050. The visualized scenarios were presented to visitors (n?=?304) in a survey to understand potential implications on visitor satisfaction. The results suggest that park managers need to find a balance between ecological integrity and visitor use in a way that ensures commercialized tourism development is limited, educational material is prioritized, and ecological integrity is maintained. While understanding the behaviour of future tourists is complex, it is a critical component of climate change adaptation planning and decision-making processes that needs to be prioritized by policymakers and PAs managers. 相似文献

This paper explores career identity and its relation to career anchors and career satisfaction, key demographic and job variables, specific to convention and exhibition (C&E) industry professionals in Asia. It reviews the key literature relating to career identity and career anchors, which is followed by a discussion of findings of an online survey of C&E industry professionals in Asia. Study results indicate that the majority of C&E professionals displayed a strong cognitive and affective identification with their career in the C&E industry. However, career identity varied significantly with the time respondents had been in the industry, job seniority and age. In terms of career anchors, the lifestyle anchor was found to be the most dominant career anchor, followed by challenge and autonomy. Examining the relation between career anchors with career identity revealed that the lifestyle anchor was more important to respondents with a weak career identity, whereas the challenge anchor was more important to respondents with a strong career identity. Managerial implications of the study findings and suggestions for future research are provided. 相似文献

Tourism self-congruity studies use two facets to personify destinations, namely, brand-as-person and brand-as-user. These features have been considered synonymous in previous research, and thus the differences between these facets, which may demonstrate biased congruity, must be investigated. This study uses projective techniques to personify brand-as-person and brand-as-user for two tourist destinations. Both facets are distinct and must not be used interchangeably in tourism-related self-congruity studies. 相似文献

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices. 相似文献

Universal Service provision has a special role for the public utilities sector in many Organization for Economic Co-operation and Development (OECD) countries. These public utilities have largely been subject to privatization during the last 3 decades. Efficiency effects of privatization are widely documented while the impacts on the quality and accessibility of the Universal Service are not much examined. By using a unique dataset on privatization for 21 countries over the period 1980–2007 for the postal sector, we are able to show that privatization, in particular formal privatization, has led to a decrease in the quality of the Universal Service. 相似文献
