long run estimates of technological change and scale economies in a dynamic framework australian permanent building societies 1974 1990 abstract this paper formulates and estimates a dynamic model to investigate the characteristics of the cost function of australian permanent building societies while the results suggest that the societies adjust costs quickly to long run levels the modelling of cost dynamics is shown to have a significant influence on estimates of scale economies and on the identification of the timing of shifts in the cost frontier and changes in the growth of total factor productivity

mixing and matching prospective financial sector mergers and market valuation abstract which types of mergers are likely to be most productive for banks and other financial firms in the us from a management perspective mixing disparate firms may be difficult but may offer significant gains from diversification the opposite applies to matching similar firms this paper considers life insurance property and casualty insurance securities and commercial firms as potential matches for banks it examines a measure of diversification gains from potential consolidation based on option pricing and a model of the building blocks of the industries based on arbitrage pricing theory the results identify potential diversification gains from virtually all combinations involving banking and insurance which arise because common factors are combined in different ways and because insurance is already well diversified

an equilibrium conflict model of land tenure in hunter gatherer societies i apply features of the economics of conflict and spatial competition in developing a model of the emergence of land ownership in hunter gatherer societies tenure regimes are the result of interactions between those seeking to defend claims to land and those seeking to infringe on those claims the model highlights the dependence of land ownership on ecological parameters such as resource density and predictability and allows for situational ownership in which the nature of ownership changes as realized ecological conditions change the paper concludes with a comparative assessment of tenure across a representative sample of hunter gatherer peoples

do mergers improve the x efficiency and scale efficiency of u s banks evidence from the 1980s a central issue currently debated among bank analysts and economists is whether mergers enhance the efficiency of surviving banks this paper investigates the postmerger performance of acquiring banks that participated in a merger during the period 1980 90 the evidence suggests that acquirers failed to improve x efficiency after the merger acquiring banks however experienced moderate gains in scale efficiency relative to a control sample the second part of the paper uses regression analysis to identify factors influencing the performance of merging banks the regression results suggest that improvements in postmerger performance depend on the ability of the bank to strengthen asset quality the author finds no evidence to support the theory that in market mergers lead to significant improvements in efficiency copyright 1997 by ohio state university press

determinants of bank growth choice abstract we study the determinants of bank growth in a two stage logistic regression model we first compare banks that branch bank acquire or product expand with banks that do not grow externally banks that are federally chartered in states with higher income growth and with higher labor prices are less likely to grow externally larger banks are more likely to grow externally in the second stage we study determinants of growth activity for banks that expand products branch or acquire other banks depending on the time period bank structure regulatory environment performance and balance sheet characteristics determine bank growth choices

alternative designs for tariffs on embodied carbon a global cost effectiveness analysis in the absence of effective world wide cooperation to curb global warming import tariffs on embodied carbon have been proposed as a potential supplement to unilateral emissions pricing we consider alternative designs for such tariffs and analyze their effects on global welfare within a multi region multi sector computable general equilibrium cge model of global trade and energy our analysis suggests that the most cost efficient policy could be region specific tariffs on all products based on direct plus electricity emissions in the end however the potential cost savings through carbon tariffs must be weighed against the administrative costs as well as legal issues and political considerations

the competitive dynamics of geographic deregulation in banking implications for productive efficiency deregulation of geographic restrictions in banking over the past 20 years has intensified both potential and actual competition in the industry the accumulating empirical evidence suggests that potential efficiency gains associated with consolidating banks are often not realized we evaluate the impact of this increased competition on the productive efficiency of nonmerging banks confronted with new entry in their local markets and find that the incumbent banks respond by improving cost efficiency thus studies evaluating the impact of bank mergers on the efficiency of the combining parties alone may be overlooking the most significant welfare enhancing aspect of merger activity

systemic risk and diversification across european banks and insurers the mutual and cross company exposures to fat tail distributed risks determine the potential impact of a financial crisis on banks and insurers we examine the systemic interdependencies within and across the european banking and insurance sectors during times of stress by means of extreme value analysis while insurers exhibit a slightly higher interdependency in comparison with banks the interdependency across the two sectors turns out to be considerably lower this suggests that downside risk can be lowered through financial conglomeration

explaining bank market to book ratios evidence from 2006 to 2009 abstract this paper examines the market price to book value ratio for 6604 bank stock observations from december 31 2006 through june 30 2009 we relate each bank s market price to book value ratio to several fundamental ratios and whether the bank took funds from the us treasury under the troubled asset relief program tarp the results of this study show that banks who took tarp funds have lower market price to book value ratios in addition lower relative costs higher non interest income and lower assets in non accrual or foreclosed status are associated with higher market price to book value ratios while controlling for size and other bank attributes

big bank mergers in europe an analysis of the cost implications this paper examines the cost implications from hypothetical cross border bank mergers in the eu in light of recent claims that substantial cost savings could be expected as the result of the eu s single market programme for financial services in fact our results suggest only limited opportunities for costs saving from big bank mergers and indicate that such mergers are more likely to result in an increase in total costs while there is a large variation in the simulated cost outcomes the greatest opportunities for cost savings would appear to be generated by mergers between german and italian banks in contrast mergers between french and german banks appear likely to result in substantial cost increases although the overall findings suggest limited benefits from cross border mergers between large banks this may be a reflection of the methodology merger simulations are carried out hypothetically ignoring any prior information about the pairings we assume no premiums or merger costs and no further synergies resulting from such things as branch closures or a restructuring of the product mix these assumptions may cause us to understate the potential reduction in total costs resulting from large bank mergers and therefore our estimates provide the most pessimistic of total cost reduction outcomes in conclusion the substantial variation of cost outcomes generated suggests that large banks seeking economies through cross border mergers should select potential partners with great care

the simple economics of bank fragility banks are linked through the interbank deposit mar ket participations like syndicated loans and deposit interest rate risk the similarity in exposures carries the potential for systemic breakdowns this potential is either weak or strong depending on whether the linkages remain or vanish asymptotically it is shown that the linearity of the bank portfolios in the exposures in combi nation with a condition on the tails of the marginal distributions of these exposures determines whether the potential for systemic risk is weak or strong we show that if the exposures have marginal normal distributions the potential for systemic risk is weak while if e g the student distributions apply the potential is strong

finding the most preferred alliance structure between banks and insurance companies in this paper we have studied alternative alliances between banks and insurance companies first we defined six different possible structure models for such alliances and nine criteria used to evaluate the models the models and the criteria were introduced together with bank and insurance experts the experts are representatives of the top management of finnish banks and insurance companies searching for the most preferred alliance model is a multiple criteria decision making mcdm problem to solve the problem we used an expert panel and the analytic hierarchy process ahp based on the evaluations of the panel the alternatives financial conglomerate and cross selling agreement no overlapping service channels are most preferred which one is chosen depends on how risk is emphasized

scale and scope economies in the multi product banking firm abstract the multi product nature of the banking firm is examined utilizing the translog cost function this analysis indicates that contrary to conventional wisdom natural monopoly scale economies and product specific decreasing costs are not robust characterizations of the banking industry there is however evidence that the cost function is characterized by economies of scope the implications of these results are discussed and extensions of this approach suggested

exclusion and the private enforcement of property rights abstract this paper develops a model of exclusion and property rights consumers choose between legal and illegal use a monopoly provider chooses a price for legal use a fine for illegal use and a level of monitoring to detect illegal use this model features a continuum of exclusion regimes instead of only the poles of private and public provision as is typical since the necessity of enforcing property rights creates two classes of users the provider is forced to price discriminate furthermore both the equilibrium and optimum feature imperfect exclusion and equilibrium exclusion is excessive

the impact of islamic banking on the cost efficiency and productivity change of malaysian commercial banks this study employs stochastic frontier analysis sfa to analyse malaysian commercial banks during 1996 2002 and particularly focuses on determining the impact of islamic banking on performance we derive both net and gross efficiency estimates thereby demonstrating that differences in operating characteristics explain much of the difference in costs between malaysian banks we also decompose productivity change into efficiency technical and scale change using a generalized malmquist productivity index on average malaysian banks experience moderate scale economies and annual productivity change of 2 68 with the latter driven primarily by technical change tc which has declined over time our gross efficiency estimates suggest that islamic banking is associated with higher input requirements however our productivity estimates indicate that full fledged islamic banks have overcome some of these cost disadvantages with rapid tc although this is not the case for conventional banks operating islamic windows merged banks are found to have higher input usage and lower productivity change suggesting that bank mergers have not contributed positively to bank performance finally our results suggest that while the east asian financial crisis had a short term costreducing effect in 1998 the crisis triggered a long lasting negative impact by increasing the volume of nonperforming loans

the sources of productivity change in spanish banking abstract in this paper we examine the pattern of productivity change in spanish banking over the period 1986 1993 two sectors dominate spanish banking commercial banks and the faster growing savings banks we begin by examining productivity change separately within each sector however since the two sectors are gradually becoming more competitive we continue by merging the two sectors and by examining productivity change in the industry the merging procedure follows a methodology originally proposed by charnes cooper and rhodes 1981 in which intra sectoral managerial inefficiency is eliminated prior to merging this procedure allows us to distinguish differences in managerial efficiency within each sector from differences in the institutional efficiency of the two sectors it also enables us to decompose potential productivity change into institutional efficiency change technical change and the impact of scale economies we find the commercial banks to have had a slightly lower rate of productivity growth but a slightly higher rate of potential productivity growth we attribute this phenomenon to differences in both managerial efficiency and institutional efficiency to differences in the rate of technical progress and to the adverse impact of diseconomies of scale in the commercial banking sector

a study of bank efficiency taking into account risk preferences abstract i use the stochastic cost frontier approach to investigate efficiency of banks operating in the third federal reserve district accounting for the quality and riskiness of bank output in addition to the mean and mode of the conditional distribution of the one sided error term i calculate confidence intervals for the inefficiency measures based on the conditional distribution the results indicate that third district banks are operating at cost efficient output levels and product mixes but are not efficiently using their inputs the second part of the article relates the inefficiency measures to several correlates

regional heterogeneity of china s energy efficiency in new normal a meta frontier super sbm analysis abstract this study aims at investigating regional heterogeneity of china s energy efficiency in the new normal a model combining meta frontier method and super sbm is proposed which has higher discriminatory power under the group frontier the energy efficiencies of the eastern central western and northeastern china and each provinces were estimated during 2006 2016 we also discussed the technology gaps of different regions the changes in energy efficiency and the main influencing factors of energy efficiency the results show that the highest energy efficiency lied in eastern china surprisingly the technology levels of central and western china have improved rapidly furthermore as china enters a new normal period more regions showed a strong decoupling relationship between energy consumption and economic growth meanwhile the regression results indicate that both state intervention and market openness had negative impacts on energy efficiency in different study periods finally according to the local conditions of different regions several policy recommendations to promote china s regional energy efficiency improvement are proposed

traditional and nontraditional banking an information theoretic approach abstract this paper uses a multiproduct approach to analyze the costs of a sample of large banks where bank outputs are measured to account for the different types of information produced by banks diseconomies of scope are found between traditional banking activities of originating and monitoring loans and nontraditional activities of loan selling and buying this suggests maintaining fire walls between commercial bank functions and investment bank functions after the glass steagall act is repealed will not sacrifice joint production economies it also suggests that arguments for repeal of the act based on the existence of such economies are ill founded

the impact of mean reversion of bank profitability on post merger performance in the banking industry abstract this research study examines the tendency for serial correlation in bank holding company profitability finding significant evidence of reversion to the industry mean in profitability the paper then considers the impact of mean reversion on the evaluation of post merger performance of bank holding companies the research concludes that when an adjustment is made for the mean reversion post merger results significantly exceed those of the industry in the first 5 years after the merger

technological change in large u s commercial banks this article examines technological change its relationship to firm size and its impact on the efficient scale of output and product mix for large u s commercial banks the results suggest that technological change lowered real costs by about one percent per year increased the cost minimizing scale of outputs and affected product mix the authors do not find support for the galbraith schumpeter hypothesis this suggests that the largest banks cannot use innovation alone to outpace smaller banks the major implications are that public policies allowing freer banking combinations do not necessarily run counter to the public interest copyright 1991 by university of chicago press

carbon emissions in china how far can new efforts bend the curve while china is on track to meet its global climate commitments through 2020 china s post 2020 co2 emissions trajectory is highly uncertain with projections varying widely across studies over the past year the chinese government has announced new policy directives to deepen economic reform to protect the environment and to limit fossil energy use in china to evaluate how new policy directives could affect energy and climate change outcomes we simulate two levels of policy effort a continued effort scenario that extends current policies beyond 2020 and an accelerated effort scenario that reflects newly announced policies on the evolution of china s energy and economic system over the next several decades we perform simulations using the china in global energy model c gem a bespoke recursive dynamic computable general equilibrium model with global coverage and detailed calibration of china s economy and future trends importantly we find that both levels of policy effort would bend down the co2 emissions trajectory before 2050 without undermining economic development specifically in the accelerated effort scenario we find that coal use peaks around 2020 and co2 emissions level off around 2030 at 10 bmt without undermining continued economic growth consistent with china reaching the status of a well off society by 2050

a framework for analyzing efficiency risks costs and innovations in the payments system the market for payment instruments such as cash checks and electronic funds transfers is one of the largest most important and economically interesting markets in the economic system virtually every economic transaction requires the use of a payment instrument therefore on a value basis the demand for payment instruments equals the demand for all other goods services assets and other financial instruments traded in the economy combined in a monetary economy the buyers and sellers of any commodity must not only agree on the price and quantity to be exchanged but must also concur on the payment method that will be employed in the exchange that is every commodity buyer takes on the role of a payor and every commodity seller takes on the role of a payee and they jointly demand a payment instrument of equal value to the commodities exchanged the size of payments markets is illustrated in table 1 which shows transactions

the deterrent effect of antitrust enforcement in this paper we formulate and test a model of collusive pricing in the presence of antitrust enforcement we show that a cartel s optimal price is likely to be neither the competitive price nor the price that the cartel would set in the absence of antitrust enforcement but rather an intermediate price that depends on the levels of antitrust enforcement efforts and penalties our empirical results reveal that increasing antitrust enforcement in the presence of a credible threat of large damage awards has the deterrent effect of reducing mark ups in the bread industry

the effects of ownership on bank efficiency in latin america in recent years many countries have privatised their state owned banks and encouraged foreign investment this article investigates the roles of state and private ownership and foreign and domestic ownership on the performance of banks across latin america using a range of financial and economic ratios data envelopment analysis dea and regression modelling the study reveals that by 2001 there was surprisingly little difference in performance between state owned and privately owned banks and between foreign and domestically owned banks the study also reports significantly different levels of bank performance in different latin american countries suggesting that country differences outweighed ownership differences in explaining performance

sector decomposition of china s national economic carbon emissions and its policy implication for national ets development abstract uncovering the contributions of each sector s driving factors to the growth of national economic carbon emissions has great significance for china in developing its nationwide emission trading scheme ets the paper applies the index decomposition analysis ida and logarithmic mean divisia index lmdi model to discuss the underlying drivers behind china s national economic carbon emissions during the period 1996 2012 from both sector and factor decomposition perspectives and accordingly offers policy proposals for china s national ets development major conclusions include 1 six heavy industry sectors the transport storage post sector and the construction sector are the largest contributors and hence proposed for incorporation into the ets s coverage 2 the rapid expansion of economic output dominantly increases carbon emissions the design of cap on emissions should allow for a proper increment and establish a new entrant reserve to coordinate economic development 3 as the dynamics of carbon emissions vary markedly across sectors allowance allocation needs to consider the changing sectoral structure of emissions 4 the combined effects of sectoral energy intensity and structure changes largely offset carbon emissions benchmarking is suggested as an ideal allocation mechanism and the setup of sectoral carbon intensity benchmark should synthetically evaluate the potential impacts of related factors 5 manufacturer based manner and carbon offset mechanism are respectively recommended for the initial implementation of carbon trading in the transport storage post sector and the construction sector

malmquist indices of productivity growth during the deregulation of norwegian banking 1980 89 productivity growth during the deregulation of the norwegian banking industry is studied within the framework of data envelopment analysis which explicitly allows for multiple outputs introducing malmquist indices for productivity growth total growth can be decomposed into frontier growth and change in each bank s distance to the frontier both the total growth index and its components can be consistently chained over time we find productivity regress at the average bank prior to the deregulation but rapid growth when deregulation took place deregulation also led to less dispersion of productivity levels within the industry

india s disappearing common lands fuzzy boundaries encroachment and evolving property rights opportunistic land encroachment occurs in many low income countries gradually yet pervasively until discrete areas of common land disappear this paper motivated by field observations in karnataka india demonstrates that such an evolution of property rights from common to private may be efficient when the boundaries between common and private land are poorly defined or fuzzy using a multi period optimization model and introducing the concept of stock and flow enforcement i show how effectiveness of enforcement effort whether encroachment is reversible and punitive fines influence whether an area of common land is fully defined and protected or gradually or rapidly encroached

do mergers improve efficiency evidence from restructuring the us electric power sector abstract this paper analyses the performance impact of the merger wave which took place in the us electricity industry during the period 1994 2003 it does so by analyzing the impact on operating and total cost in electricity distribution while there are past studies of efficiency and productivity effects as well as of prices profits and other outcomes this study differs in several ways first the database consists of many merging and non merging firms rather than only a few on which to base inferences second all of these mergers arise in a single industry greatly facilitating controlled comparison third we have data on the several years of pre merger and post merger efficiency of the specific merging units unlike virtually all past studies finally we employ a powerful nonparametric technique data envelopment analysis to measure the efficiency of each operating unit the results indicate that electricity mergers are not consistent with improved cost performance

banks responses to deregulation profits technology and efficiency the deregulation of interest rates in the early 1980s raised bank funding costs and lowered profits in response banks raised fees for deposit services reduced branch operating costs and shifted to higher earning assets rates of return did not regain their prederegulation levels until the early 1990s our goal is to decompose the change in bank profits following deregulation into i intemal bank initiated adjustments to the new regulatory structure and ii external contemporaneous changes in banks business environment this decomposition will depend in part on the assumed competitive structure of the banking industry with perfect competition output and input prices are part of the external environment and banks responses are limited to changes in output and input quantities an alternative approach assumes imperfect competition where banks have some control over output prices deposit fees minimum balance requirements and interest rates on certain loans and output quantities and input prices comprise the external environment the altemative model is supported by the data using this model large banks but not smaller banks are found to have relied primarily on changing output prices and input use to mitigate and reverse the negative effects of deregulation on profits the adjustment to deregulation was essentially complete after four years following this additional changes in bank profitability during the late 1980s were primarily due to changes in banks business environment

output allocative and technical efficiency of banks abstract in this paper we calculate output allocative and technical efficiency for a sample of small banks operating in 1982 we do so by estimating a shephard type output distance function as a deterministic frontier in general we find that the banks in our sample are output inefficient

synergy between pollution and carbon emissions control comparing china and the united states abstract we estimate the potential synergy between pollution and climate control in the u s and china summarizing the results as emissions cross elasticities of control in both countries ancillary carbon reductions resulting from so 2 and no x control tend to rise with the increased stringency of control targets reflecting the eventual need for wholesale change toward non fossil technologies when large reductions are required under stringent pollution targets the non target effects tend to be higher in china than in the u s due to china s heavy reliance on coal this result suggests that china may have greater incentives to reduce so 2 and no x with locally apparent pollution benefits but related efforts would at the same time reduce co 2 emissions significantly we also find strong non target effects of co 2 abatement in both countries but the cross effects in this direction depend less on the stringency of control and are stronger in the u s than in china

limited trading of emissions permits as a climate cooperation mechanism us china and eu china examples abstract recent multilateral climate negotiations have underlined the importance of international cooperation and the need for support from developed to developing countries to address climate change this raises the question of whether carbon market linkages could be used as a cooperation mechanism policy discussions surrounding such linkages have indicated that should they operate a limit would be set on the amount of carbon permits that could be imported by developed regions from developing countries this paper analyzes the impact of limited carbon trading between an ets in the eu or the us and a carbon market covering chinese electricity and energy intensive sectors using a global economy wide model we find that the limit results in different carbon prices between china and europe or the us although the impact on low carbon technologies in china is moderate global emission reductions are deeper than in the absence of international trading due to reduced carbon leakage if china captures the rents associated with limited permit trading we show that it is possible to find a limit threshold that makes both regions better off relative to carbon markets operating in isolation

the role of china in mitigating climate change abstract we explore short and long term implications of several energy scenarios of china s role in efforts to mitigate global climate risk the focus is on the impacts on china s energy system and gdp growth and on global climate indicators such as greenhouse gas concentrations radiative forcing and global temperature change we employ the mit integrated global system model igsm framework and its economic component the mit emissions prediction and policy analysis eppa model we demonstrate that china s commitments for 2020 made during the un climate meetings in copenhagen and cancun are reachable at very modest cost alternative actions by china in the next 10 years do not yield any substantial changes in ghg concentrations or temperature due to inertia in the climate system consideration of the longer term climate implications of the copenhagen type of commitments requires an assumption about policies after 2020 and the effects differ drastically depending on the case meeting a 2 c target is problematic unless radical ghg emission reductions are assumed in the short term participation or non participation of china in global climate architecture can lead by 2100 to a 200 280 ppm difference in atmospheric ghg concentration which can result in a 1 1 c to 1 3 c change by the end of the century we conclude that it is essential to engage china in ghg emissions mitigation policies and alternative actions lead to substantial differences in climate energy and economic outcomes potential channels for engaging china can be air pollution control and involvement in sectoral trading with established emissions trading systems in developed countries

the impact of liberalization on the productive efficiency of indian commercial banks abstract we examine the productive efficiency of 70 indian commercial banks during the early stages 1986 1991 of the ongoing period of liberalization we use data envelopment analysis to calculate radial technical efficiency scores we then use stochastic frontier analysis to attribute variation in the calculated efficiency scores to three sources a temporal component an ownership component and a random noise component we find publicly owned indian banks to have been the most efficient followed by foreign owned banks and privately owned indian banks we also find a temporal improvement in the performance of foreign owned banks virtually no trend in the performance of privately owned indian banks and a temporal decline in the performance of publicly owned indian banks we attempt to explain these patterns in terms of the government s evolving regulatory policies

bank capitalization and cost evidence of scale economies in risk management and signaling we amend the standard cost model to account for the role of financial capital in banking the cost function is conditioned on the level of capital but we model the demand for financial capital so that it can serve as a cushion against insolvency for potentially risk averse managers and as a signal of risk for less informed outsiders scale economies are then computed without assuming that the bank chooses a level of capitalization that minimizes cost we find evidence of substantial scale economies and that bank managers are risk averse and use the level of financial capital to signal the level of risk

the impact of underwriting and dealing on bank returns and risks abstract this study uses portfolio theory to investigate empirically the potential for diversification gains from expanded bank securities powers diversification potential is examined using microeconomic data on returns to existing bank securities and non securities activities over 1976 through 1985 both the mean and standard deviation of returns to securities activities are found to be greater than those of non securities activities some potential for diversification gains is found although this appears to be quite limited experiments designed to estimate the effect of using industry and time aggregated data are performed

technical change organizational form and the structure of bank production of those technological characteristics related to the nature of competition among firms in an industry or market scale economies and technical change are especially important economies of scale are said to exist when an equiproportional increase in all inputs results in a greater than proportional increase in output or equivalently when an increase in output at constant input prices leads to a less than proportional increase in total costs thus average costs decline as output expands depending upon the extent to which costs decline as output increases regulation of the firms in the industry may be necessary l the literature analyzing scale economies in commercial banking is voluminous the early studies on scale economies in banking include those by benston 1965 1972 greenbaum 1967 murphy 1972 and bell and murphy 1968 more recent studies include those by benston hanweck and humphrey 1982 and clark 1984 2 this literature has established that mild scale economies exist in bank

technical scale and allocative efficiencies in u s banking an empirical investigation a nonparametric frontier approach is used to calculate the overall technical pure technical allocative and scale efficiencies for a sample of 322 independent banks the sample was drawn from the federal deposit insurance corporation tapes on the reports of condition and reports of income call reports for the year 1986 the results indicated a low level of overall efficiency the main source of inefficiency was technical in nature rather than allocative separate efficiency frontiers were constructed to test the effect of branching however the distributions of efficiency measures for branching and non branching banks were not found to be different

the productivity effects of bank mergers evidence from the uk building societies abstract this paper presents an empirical investigation of the impact of acquisition activity on financial intermediary productivity specifically it uses an augmented production function approach to investigate the impact of acquisition after controls for input changes the model is estimated on an unbalanced panel of 93 uk building societies over the period 1981 1993 using data on their core financial intermediation activities which it is suggested are particularly appropriate for our purposes in contrast to much of the existing merger literature which for the most part uses financial performance data our results do indicate significant and substantial productivity gains following acquisition these are consistent with an acquisitions process in which less efficient firms are acquired and reorganized the post merger gains appear to increase substantially in the post deregulation period when pressures to minimize cost are widely considered to have increased

short run cost inefficiency of commercial banks a flexible stochastic frontier approach we adopt the intermediation approach and use a flexible stochastic frontier to examine the cost efficiency of united states commercial banks with total assets in excess of million we find an average overall inefficiency of just under 10 percent a level somewhat lower than found in previous work our analysis of intra industry variation concludes that inefficiency generally rises with bank size further banks that have branching networks either domestic or foreign have higher inefficiency on average but at the same time inefficiency falls as the number of offices in the branch network expands state level data on the ease of serviceing the market competition from savings institutions and the financial sophistication of depositors significantly affect bank inefficiency generally with the expected signs finally our findings suggest that regulatory changes that increase capital requirements may lead to increased bank efficiency in the short run copyright 1994 by ohio state university press

megamergers and expanded scope theories of bank size and activity diversity we point to the vast empirical literature in banking to argue that the current expansion of scale and scope in banking represents a puzzle we then present two explanations that help us to understand why banks are getting bigger and doing more our explanations suggest that banks may be doing this to increase their shareholders wealth and or merely to enhance the reputation of their management ceos the latter could lead to herd behavior involving banks that increase size and scope despite a dissipation of shareholders wealth alternatively increasing size and scope may oaer strategic benefits and hence increase shareholder wealth in an environment with suacient profitability in current operations and substantial uncertainty about future core competencies we explore conditions under which either one of these competing explanations may dominate 1999 elsevier science b v all rights reserved

a model of regulated open access resource use abstract this paper develops a model of regulated open access resource exploitation the regulatory model assumes that regulators are goal oriented choosing target harvest levels according to a safe stock concept these harvest quotas are implemented by setting season lengths conditioned on the industry fishing capacity the industry enters until rents are dissipated conditioned on season length regulations harvest levels fishing capacity season length and biomass are determined jointly using parameter estimates from the long regulated north pacific halibut fishery predictions of these variables from the regulated open access model are compared to predictions that arise from the gordon model

the efficiency effects of a single market for financial services in europe abstract this paper examines the potential efficiency effects of a single market for financial services in europe the topics covered include universal banking the merger and acquisition process itself cross border ownership and management of financial institutions and the effects of consolidation of financial institutions on the supply of relationship lending services to informationally opaque small businesses the research reviewed here suggests that the creation of a single market for the european financial services industry is not likely to bring about strong efficiency gains and that cross border efficiency barriers may prevent the single market from becoming a reality

efficiency in the savings and loan industry abstract the stochastic econometric cost frontier approach is modified to investigate efficiency in mutual and stock s ls using 1991 data on u s s ls this methodology allows both the cost frontier and error structures to differ between s ls of these two ownership forms a likelihood ratio test indicates that the data support this unrestricted model which implies efficient mutual and stock s ls use different production technologies various measures of inefficiency show that on average stock s ls are less efficient than mutual s ls the second part of the article relates the inefficiency measures to several correlates

carbon dioxide co2 emissions during urbanization a comparative study between china and japan as the world s largest emitter of co2 china is facing increasing domestic and international pressures on emissions mitigation considering japan s leading position in energy conservation this paper conducts a comparative study between china and japan at the urbanization stages to analyze the similarities as well as differences of influencing factors of co2 emissions results indicate that although co2 emissions in japan and china showed the similar characteristics of rigid growth during the urbanization processes significant differences exist in factors such as co2 emissions per capita energy structure and energy intensity between the two countries which are the determinants for co2 emissions growth a cointegration model is constructed to examine the long run equilibrium relationship between co2 emissions and factors including gdp urbanization level energy intensity and cement manufacture empirical results show that there is a quadratic relationship between income growth and co2 emissions granger causality test is then adopted to explore the causal relationships among the variables the future co2 emissions and emission reduction potentials in china are estimated based on scenario analysis finally japan s valuable experience of reducing energy intensity and optimizing energy structure is concluded to provide important policy implications for china s strategic low carbon planning and low carbon transition

mergers and technical efficiency in spanish savings banks a stochastic distance function approach abstract the aim of this paper is to test the temporal variation of technical efficiency of spanish savings banks during the period 1985 1998 furthermore we test whether merged and non merged firms have different levels and temporal patterns of technical efficiency a stochastic output distance function r w shephard theory of cost and production functions princeton university press princeton nj is employed to accommodate multiple output technology the distance function provides the advantage that it does not need information about prices so it can accommodate the multi product nature of the financial sector only using the quantities as data an important point when the assumptions about perfectly competitive markets are unlikely to be met the temporal variation of efficiency is modeled extending the battese and coelli journal of productivity analysis 3 1992 153 169 approach in two ways relaxing the monotonicity of the temporal variation pattern of the efficiency term and allowing for different patterns of efficiency change between merged and non merged firms

property rights by squatting land ownership risk and adverse possession statutes a fundamental aspect of private property is the right to exclude trespassers or squatters nonetheless in all 50 states a trespasser can acquire ownership by continuously occupying a parcel of land until the statutorily set period of limitations runs out although these adverse possession statutes appear to weaken property rights this paper explains how such limits are valuable to property owners by balancing the risk of claims from past legitimate owners against the cost of expelling future trespassers or squatters the empirical analysis using data from 46 states provides evidence that is consistent with the theory

decoupling co2 emission and economic growth in china is there consistency in estimation results in analyzing environmental kuznets curve china is one of the highest growth economies in the world and it has experienced a significant rise in energy consumption and greenhouse gas emissions in recent decades its economic growth heavily depends on fossil fuels of coal and oil which led to huge amount of greenhouse gas emissions this study logically analyzes the nexus of co2 emissions economic growth and energy consumption by decoupling greenhouse gas emission of co2 and economic growth to provide more conclusive evidence on the phenomenon of the environmental kuznets curve ekc over the period 1970 2015 to achieve the objective of consistency in the estimation results the study applies different estimation techniques such as ardl auto regressive distributed lag model fmols fully modified ordinary least squares dols dynamic ordinary least squares and impulse response and variance decomposition in addition the business as usual inverted u shaped relationship between gdp per capita and an economy related co2 emission is hypothesized the result supports the environmental kuznets curve ekc hypothesis from different techniques the turning point hovers around 744665 the estimation result indicates that china ekc turning point shows some inconsistencies when compared to other turning points obtained from different studies the inconsistency of the ekc turning point is attributed to the sensitivity of the result to different data source variables selection different pollutants and scope of the data although the ekc turning point of this present research differs from other china ekc turning points it gives a clear policy roadmap on the pursuance of long run economic growth in favour of environmental quality besides significance of the turning point lies with the need to explore other structural policies such as articulated demographic and energy policies rather than passively waiting for the arrival of the inflexion point one interesting findings of the analysis is the consistency of the estimation results from the different estimation techniques

technical progress inefficiency and productivity change in u s banking 1984 1993 studies often find that on average u s commercial banks are quite inefficient and the authors find that banks became more technically inefficient between 1984 and 1993 from a new decomposition of the malmquist productivity index into changes in pure technical and scale efficiency as well as both pure technical changes and changes in scale of technology they find that much of the inefficiency increase can be attributed to the general failure of banks to adopt technological improvements made by a few banks that advanced the efficient frontier small banks experienced especially large decreases in both efficiency and productivity

explaining efficiency differences among large german and austrian banks cost efficiency scale efficiency and productivity change are estimated by data envelopment analysis and cost efficiency is regressed on explanatory variables no evidence is found for average productivity responding to deregulation over the period studied state owned banks are found to be more cost efficient likely owing to cheaper funds and cooperative banks to be about as cost efficient as private banks increasing economies of scale but decreasing economies of scope provide rationale for m as among banks with similar product portfolios interbank and capital market funding is found to be more cost efficient than deposits when the cost of retail networks is controlled

merger and optimal number of firms an integrated simulation approach in a market where imperfect competition occurs as a result of mergers this study proposes a framework consisting of both efficiency and risk analyses that allow the simulation of pro forma mergers and hence the determination of the optimal number of firms in the industry this is valuable policy information for regulators concerned with possible intervention in the case of competition and anti trust violations and also for business managers seeking acquisition targets the framework is applied to the banking industry in taiwan results reveal the potential for industrial restructuring in a sector where the optimal number of bank holding companies bhcs is between four and six subject to whether partial control is assumed

regulations market structure institutions and the cost of financial intermediation this paper examines the impact of bank regulations market structure and national institutions on bank net interest margins and overhead costs using data on over 1400 banks across 72 countries while controlling for bankspecific characteristics the data indicate that tighter regulations on bank entry and bank activities boost the cost of financial intermediation inflation also exerts a robust positive impact on bank margins and overhead costs while concentration is positively associated with net interest margins this relationship breaksdownwhencontrolling for regulatory impediments to competition and inflation furthermore bank regulations become insignificant when controlling for national indicators of economic freedom or property rights protection while these institutional indicators robustly explain cross bank net interest margins and overhead expenditures thus bank regulations cannot be viewed in isolation they reflect broad national approaches to private property and competition

evaluation of price policy in the presence of water theft mathematical programming models of representative farms are commonly used to evaluate policies such as input subsidies and output price supports on canals in india upstream farmers routinely use more irrigation water than allotted in such circumstances the programming model should encompass farmers locational heterogeneity here a representative watercourse with thirty farms is calibrated to the eight crops fifteen irrigation turns yield responses to water and seepage in maharashtra not only does water theft increase the social cost of price policies but the policies increased inducement to theft by upstream farmers leaves those downstream with less water and lower incomes

swords or plowshares a theory of the security of claims to property this paper develops a general equilibrium model of the allocation of resources among appropriative and productive activities the model emphasizes the distinction between offensive weapons which are the instruments of predation and fortifications which provide defense against predation the analysis of this model shows how the equilibrium security of claims to property is determined the analysis focuses on the possibility of a nonaggressive equilibrium in which no resources are allocated to offensive weapons and claims to property are fully secure we also analyze the complex relation between economic welfare and the security of claims to property we find for example that a relatively poor agent could be better off in an equilibrium with less secure claims to property

measuring cost efficiency in the property liability insurance industry abstract escalating prices and periodic availability problems in property liability insurance markets are often attributed to insurance company inefficiency and lax claims settlement practices this paper investigates these issues by estimating stochastic cost frontiers for three size stratified samples of property liability insurers over the period 1980 1988 a translog cost function and input share equations are estimated using maximum likelihood techniques the results show that large insurers operate in a narrow range around an average efficiency level of about 90 percent relative to their cost frontier efficiency levels for medium and small insurers are about 80 and 88 percent in relation to their respective frontiers wider variations in efficiency are present for these two groups in comparison with large insurers large insurers slightly over produce loss settlement services while small and medium size insurers under produce this output the small and intermediate size groups are characterized by economies of scale suggesting the potential for cost reductions from consolidations in the industry

bidder returns in bancassurance mergers is there evidence of synergy abstract we provide evidence on the potential for bidder wealth gains in bancassurance mergers by examining a sample of such mergers in the united states and abroad these combinations are expected to produce positive wealth gains if there are synergies between these two types of financial firms we find positive bidder wealth effects that are significantly related to economies of scale as measured by the size of the target relative to the bidder potential economies of scope and the locations of the bidders and targets these results suggest that the bancassurance architectural structure for financial firms does offer some benefits and thus may become more prominent in future years
