optimal contracting and the organization of knowledge we study contractual arrangements that support an efficient use of time in a knowledge intensive economy in which agents endogenously specialize in either production or consulting the resulting market for advice is plagued by informational problems since both the difficulty of the questions posed to consultants and the knowledge of those consultants are hard to assess we show that spot contracting is not efficient because lemons in this case self employed producers with intermediate knowledge cannot be appropriately excluded from the market however an ex ante firm like contractual arrangement uniquely delivers the first best this arrangement involves hierarchies in which consultants are full residual claimants of output and compensate producers via incentive contracts this simple characterization of the optimal ex ante arrangement suggests a rationale for the organization of firms and the structure of compensation in knowledge intensive sectors our findings correspond empirically to observed arrangements inside professional service firms and between venture capitalists and entrepreneurs

x efficiency in australian banking an empirical investigation this paper empirically investigates the x eaciency technical and allocative in australian banks a non parametric method of data envelopment analysis dea has been used to arrive at the eaciency scores banks in this sample were found to have low levels of overall eaciency compared with the banks in the european countries and in the us the results indicate that as a source of overall ineaciency the technical component was more important than the allocative component thus the ineaciency in australian banks can be attributed to wasting of inputs technical ineaciency rather than choosing the incorrect input combinations allocative ineaciency domestic banks were found to be more eacient than foreign owned banks the study has important implications such as guiding the government policy regarding deregulation and mergers since the study pinpoints the sources of ineaciency it would also help banks with strategic planning 2001 elsevier science b v all rights reserved

energy transitions in small scale regions what we can learn from a regional innovation systems perspective the prevalent theories in the debate on sustainability transitions have been criticised for not sufficiently addressing energy change processes at the local level this paper aims to enhance our understanding of local energy reorganisation processes drawing on the regional innovation systems ris approach we argue that local development dynamics result from the interaction of various subsystems science politics public administration industry finance intermediaries and civil society the analysis of the involved subsystems and their interaction shows how energy transitions are shaped by different individual and organisational actors as well as institutions on the local level empirical evidence from case studies on the german cities of emden and bottrop illustrates our theoretical conceptualisation of energy transitions we conclude by presenting characteristic interaction patterns for energy transition drawn from the two cases

banking technology and the existence of a consistent output aggregate abstract this paper addresses the question of the existence of a consistent output aggregate in banking specific necessary and sufficient conditions for output aggregation are developed and tested in the context of a second order approximation to any arbitrary multi product bank cost function the analysis provides evidence that a composite aggregate measure of output fails to provide a proper representation of banking technology and therefore previous studies that used aggregate output measures may well be subject to specification errors

banking costs generalized functional forms and estimation of economies of scale and scope recently researchers have claimed that the primitive cobb douglas production technology captures banking cost functions adequately these findings rule out scope economies and u shaped cost curves the rejection of the generalized flexible form postulated by the above authors is a necessary but not a sufficient condition to justify a cobb douglas specification using restricted generalized functional forms the authors find that the composite output cobb douglas specification is an inadequate description of banking cost technology translog specifications with multiple products capture the data best suggesting the presence of both scope and scale economies copyright 1989 by ohio state university press

costly communication and incentives this paper discusses the introduction of incentive considerations in a model of costly communication it starts from a simplified version of a team theoretic model due to dessein and santos 2003 which relates the design of an organization to its adaptiveness to environmental uncertainty incentives are introduced in this setting following an approach developed by dewatripont and tirole 2005 doing so enriches the analysis by allowing for the coexistence of various forms of communication in particular cheap talk versus costly communication 2006 by the european economic association

planning of renewables schemes deliberative and fair decision making on landscape issues instead of reproachful accusations of non cooperation abstract the main issues related to successful implementation policies concern the socio economic institutions that are conditional to planning in the energy policy domain but also in the domain of spatial planning successful investments and the siting of renewable power plants eventually determine the success rate of national efforts in establishing renewable capacity central planning usually has several objectives and these often have a detrimental effect on the goal of renewable energy application current problems related to implementation decisions concerning wind power schemes are an example to those who will be faced by other renewable power plants notably biomass regarding community acceptance of wind power schemes the visual evaluation of the impact of wind power on the values of the landscape is by far the most dominant factor in explaining opposition or support type of landscape fully overshadows other attitudinal attributes as well as other visual and scenic factors such as the design of wind turbines and wind farms and the number and the size of turbines planning regimes and decision making practices that really enhance the implementation processes of renewable energy require strong ecological modernization this means institutional changes that create involvement and trust of actors at the actual implementation level local opposition cannot be explained by the egotistical motives of local residents when the inclination to behave according to supposed backyard motives is investigated the scale to measure this phenomenon appears to indicate commitment to equity issues and fairness of decision making hence for wind power local involvement to represent the local values of site specific landscapes is crucial for other renewables the source specific features are different but conflicts can be expected as well because the fairness of implementation decisions will be equally significant

an empirical investigation of changes in scale economies for the commercial banking firm 1979 1986 the period of the 1980s represents a particularly turbulent time for the banking industry a number of technological and regulatory changes have occurred including the elimination of regulation q which had limited the explicit interest payments that banks could pay on some types of deposits it would be expected that these changes would affect the structure of costs for banks the behavior of the cost function is studied over the 1979 1986 time period and in contrast to previous studies using earlier data increasing economies of scale are found in the later years for banks in both unit and branch banking states these results indicate that there may be increased cost pressure for smaller banks to become larger either through mergers and acquisitions or through internal growth this may lead to further consolidation pressures within the industry and reductions in the overall number of banking firms copyright 1991 by ohio state university press

firm size wage gaps job responsibility and hierarchical matching i present the fact that wage gaps due to firm size increase with job responsibility i use swedish data to determine whether wage gaps increase with a direct measure of job responsibility to compare the age patterns of the wage gaps for blue and white collar workers and to compare wages by job responsibility and spans of control with u s data i compare supervisory to nonsupervisory occupations and find that wage gaps increase with job responsibility for most occupational ladders this fact is consistent with hierarchical matching models in which the larger number of subordinates amplifies managerial talent

estimating willingness to pay for renewable energy in south korea using the contingent valuation method the importance of renewable energy as a response to climate change is universally acknowledged however its successful implementation requires public approval and cooperation this study aims to identify the level of renewable energy acceptance in korea by estimating korean consumers additional willingness to pay wtp using the contingent valuation cv method which is the most widely used to analyze consumer preferences the estimation results indicate that korean consumers are willing to pay an additional usd 3 21 per month for electricity generated with renewable energy however wtp in korea is low relative to other advanced nations indicating that these values could be influenced through policies aimed at improving knowledge and acceptance of renewable energy sources among korean consumers

economies of scale and scope in the securities industry abstract economies of scale and scope for the securities industry are estimated for the first time using previously unavailable survey data and employing the translog multiproduct cost function model the results reveal economies of scale for smaller specialized firms and diseconomies of scale for larger more diversified firms economies of scope do not appear to be important in the industry if the glass steagall restrictions are relaxed the results suggest that banks can enter the securities industry with a brokerage division of moderate scale of about 30 million in revenues the five million in new equity required suggests that only banks with assets over 1 billion and over 60 million in capital can enter the industry with a relatively modest investment there are however a substantial number of banks with over 1 billion in assets who can be considered as potential entrants

undesired reinforcement of harmful self evident truths concerning the implementation of wind power abstract this viewpoint draws attention to a lingering simplistic and faulty interpretation of the complex phenomenon of acceptance of renewables and their implementation in concrete projects by all relevant actors namely the backyard theory during the last decade research that investigated nimby has provided support to disprove the two prime hypotheses proximity and decreasing property value the current mainstream trend in academic circles is clearly towards abandoning nimby explanations however in practice among developers and policymakers nimby thinking still prevails unfortunately there is also some academic writing that persists in recycling the backyard theory despite ample research to the contrary thus feeding this faulty interpretation of implementation problems a recent review of the state of the art of wind power implementation is taken as an example it presents nimby as a common sense self evident truth while to support this explanation it cites publications that actually refute this view and instead support the mainstream move towards abandoning nimby thinking this shift is important because further academic support for this concept would serve to hinder rapid deployment of wind power and also other renewables

hierarchical organization and performance inequality evidence from professional cycling this article proposes an equilibrium theory of the organization of work in an economy with an implicit market for productive time in this market agents buy or sell productive time this implicit market gives rise to the formation of teams organized in hierarchies with one leader buyer at the top and helpers sellers below relative to autarky hierarchical organization leads to higher within and between team payoffs productivity inequality this prediction is tested empirically in the context of professional road cycling we show that 46 of performance inequality in the tour de france is due to hierarchical organization within team whereas team composition only accounts for 6

measuring economies of diversification a frontier approach the purpose of this article is to improve the statistical analysis of multiproduct firm behavior specifically we are interested in modeling and estimating multiproduct technology focusing on size and product line variation thus we offer a new empirical technique that can be used to directly analyze issues such as subadditivity expansion path subadditivity economies of scope and economies of diversification although applied papers employ a wide variety of theoretical multiproduct cost concepts previous work uses nonfrontier estimation techniques we show how to introduce frontier approaches to multiproduct cost analysis that can be applied to any of these concepts and improve the statistical analysis specifically we introduce an empirical test using frontier techniques that allows for direct measures of economies of diversification at the firm specific level

how do banks respond to shocks a dynamic model of deposit taking institutions abstract this paper proposes a dynamic model of the optimal choices of a bank that benefits from market power and takes into account the impact of the deposit generation process interbank lending borrowing emerges as a buffer that assists the bank in smoothing intertemporal adjustments in interdependent loan and deposit choices the bank smooths the impact of interest rates shocks on its customers to minimize the adjustments over time of the stocks of deposits and loans it does not however provide insurance against negative shocks of real origin that increase its expected default costs the predictions of the model help to shed light on the available empirical evidence and to analyze some recent developments of the banking industry

a microfoundation for production functions assignment of heterogenous workers to heterogenous jobs in very different fields of economics economic inference and policy evaluation require economists to parametrize a production function that links measures of input factors to measures of output while doing so strong assumptions are implicitly made about microeconomic variables governing the shape of the aggregate production function in this paper i develop an assignment model that provides a microeconomic foundation for aggregate production functions the shape of the production function depends crucially on the distribution of workers and jobs and the type of technological changes depends crucially on the evolution of these distributions sufficient and necessary conditions are provided for the production function to be of the constant ratio of elasticities of substitution form a form nesting the broadly used constant elasticity of substitution form this model provides a way to evaluate how stringent assumptions about the type of production function or technological change are by comparing the implied distribution of jobs and its evolution over time to observations of the distribution of jobs and its evolution over time

an empirical analysis of scale and scope economies and technical change in an irish multiproduct banking firm abstract in contrast to most empirical investigations of the efficiency of multiproduct financial institutions which either estimate scale and scope economies with a given state of technology or only analyse technical change in the presence of overall scale economies this study estimates overall scale economies product specific scale economies and scope economies in the presence of both neutral and non neutral technical change also in contrast to most other empirical studies in this area standard errors are computed for all relevant statistics the findings indicate diseconomies of scope overall diseconomies of scale product specific economies are decreasing for investments and increasing for loans in addition to substantial neutral technical change biased technical change is labour and capital saving and deposits using in character

matching problems with expertise in firms and markets when should expertise be shared in markets and when in firms knowledge exchanges in the market involve less information about the quality of the provider s expertise but facilitate good utilization of experts knowledge in a firm management holds soft information about individuals expertise and thus improves on the matching of experts to problems however the usage of experts is not smooth and thus firms experience over or underutilization of experts time thus the trade off between firms and markets is between utilization the market allows for better smoother utilization of knowledge than firms and the quality of matching between problems and problem solvers the market provides less information about experts quality

maturity intermediation and intertemporal lending policies of financial intermediaries this paper considers the maturity intermediation and intertemporal lending decisions of risk averse financial intermediaries in particular the maturity mismatch problem and the fixed versus variable rate lending decision are modeled when the major source of risk involves uncertain future interest rates the results imply that the strategy of matching the maturity of assets and liabilities is not generally optimal or even minimum risk this is due primarily to the built in hedge that the intermediary has as a result of rolling over short term loans while continuing to finance long term loans intertemporal dependencies between loan demand and costs or both also have an effect on the optimal degree of maturity mismatching and provide one rationale for making loans at rates below current marginal cost

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

the taxation of superstars how are optimal taxes affected by the presence of superstar phenomena at the top of the earnings distribution to answer this question we extend the mirrlees model to incorporate an assignment problem in the labor market that generates superstar effects perhaps surprisingly rather than providing a rationale for higher taxes we show that superstar effects provide a force for lower marginal taxes conditional on the observed distribution of earnings superstar effects make the earnings schedule convex which increases the responsiveness of individual earnings to tax changes we show that various common elasticity measures are not sufficient statistics and must be adjusted upwards in optimal tax formulas finally we study a comparative static that does not keep the observed earnings distribution fixed when superstar technologies are introduced inequality increases but we obtain a neutrality result finding tax rates at the top unaltered

the role of fixed costs and cost complementarities in determining scope economies and the cost of narrow banking proposals narrow banking proposals would separate insured deposits from most types of bank lending using data from large u s banks the authors examine the extent to which narrow banking proposals are likely to result in increased production costs production costs will rise for nonjoint provision of deposit and loan services if there are cost complementarities in producing the two outputs jointly or if joint production enables banks to spread their fixed costs more effectively unlike standard cost function approaches the authors methods allow them to estimate the fixed cost and cost complementarity effects separately they find the net production cost consequences of narrow banking to be negligible copyright 1993 by university of chicago press

multiproduct technology and market structure a recent line of research has exposed some technological determinants of the structure of industries that produce more than one good the analyses of both multiproduct perfect competition and natural monopoly require a generalized notion of average cost and in addition several newly identified technological characteristics pertinent only to joint production this paper provides an overview of these new results and suggests a unifying framework in which the theory can be further developed

nimby or not exploring the relevance of location and the politics of voiced opinions in renewable energy siting controversies local protests against renewable energy facilities have added fuel to the debate about the so called nimby not in my back yard effect this paper identifies six variables that can hamper the comparison between different public perception studies and offers two broad conclusions on aggregate proximity does have strong influence on public attitudes to proposed projects but the nature strength and spatial scale of this effect may vary according to local context and value of the land residents of stigmatised places are more likely to welcome facilities that are relatively green while people who derive a more positive sense of identity from particular rural landscapes are likely to resist such potential developments especially if they also live there secondly the fear of being branded a nimby and the positive ethics associated with the notion of renewable are both likely to colour the responses of many interviewees these aspects need to be clarified and accounted for in analyses of elicited responses both quantitative and qualitative if we are to improve our understanding of the social construction of individual attitudes in siting conflicts

economies of scale in building societies this paper presents new measurements of economies of scale in the building society industry by estimating a translog total cost function jointly with the derived input cost share equations it differs from previous building society studies by defining total cost to include the interest cost of borrowed funds as well as the operating costs of employing labour and capital services in addition to the usual elasticity three further scale economy measures are developed and estimated input specific economies of scale augmented economies of scale and augmented input specific economies of scale

scale economies and cost complementarities in commercial banks on and off balance sheet activities abstract bank off balance sheet obs activities have grown dramatically and have become significantly important especially at large banks we investigate whether failure to incorporate obs products may lead to a misspecification problem models that exclude deposits from the output specification suggest economies of scale which vanish when deposits are included we find that inclusion of obs products has little effect on the scale economies measures with only a few exceptions the results provide no evidence of cost complementarities in joint production the tremendous growth of bank obs activities in the 1980s may be explained by the very small approximately zero pecuniary cost of these activities

scale economies in banking a restructuring and reassessment the issue of scale economies in banking has a rich history most earlier studies report modest operating cost scale economies for small institutions those with less than about 50 million of deposits in 1968 dollars but are unclear where these economies might end if at all unfortunately these studies are limited in four important respects first those that were well specified did not measure the total cost of banking operations but concentrated on estimating scale economies for individual banking functions e g demand deposits separately from commercial loans second an average cost curve that could take a u shape over the full range of banks was not fitted either because larger banks were not included or because of the functional form used cobb douglas consequently the optimum or minimum cost size of a bank or office could not be determined third the variables measuring the costs of branching were misspecified fourth the branch

economies of scale and economies of scope in multiproduct financial institutions a study of british columbia credit unions this paper investigates the production technology facing computerized credit unions in canada a full system of translog cost equations is estimated in order to test for economies of scale economies of scope and other production characteristics in a multiproduct context the regression results indicate that most of the credit unions in our sample experience significant increasing returns to scale as they expand their level of output there is also evidence of cost complementarity or economies of scope in their mortgage and other lending activities as a result legislation which limits the ability of credit unions to grow and diversify will likely raise the operating costs of this important group of financial institutions additional structural tests of the most general translog specification suggest that none of the restrictive production conditions commonly imposed by other researchers using cobb douglas and ces specifications provide a valid representation of credit union technology the results of many earlier studies are therefore open to question this paper presents a number of structural tests of the production technology facing large computerized credit unions in canada a full system of translog cost equations is estimated using detailed cross sectional data on british columbia credit unions the parameter estimates obtained from our multiproduct specification allow us to test for economies of scale economies of scope and factor substitution unlike many earlier studies the present paper introduces the various outputs as separate variables instead of crudely proxying them with a single output measure such as total assets the total number of loans or the number of depositors by explicitly recognizing the multiproduct nature of the intermediation process we are able to address more interesting production questions and remove some of the bias caused by misspecification and measurement error in simpler approaches the flexible translog specification allows us to estimate the sensitivity of costs to proportionate increases in all outputs economies of scale as well as the cost savings firms realize by producing several outputs jointly rather than specializing in the production of one economies of scope the test results reported in the latter part of the paper suggest that increasing returns to scale exist in almost all of the credit unions in our sample though

japan s post fukushima challenge implications from the german experience on renewable energy policy the japanese electricity sector is facing serious challenges in the aftermath of the fukushima nuclear disaster the government has responded to the crisis with a new feed in tariff to promote increased utilization of renewable energy and proposed to reduce the dependence on nuclear power in this viewpoint we liken the transition implied by recently updated goals for the diffusion of renewables in japan to the transition in germany in the last decade we argue that some of the lessons learned in germany might prove valuable for the steps japan considers taking in particular we focus on the new japanese feed in tariff for solar photovoltaics in view of the recent developments in germany we emphasize the importance of the scheme s political legitimacy which needs to be maintained through adequate design of both policy instrument and political process we conclude with policy implications and a targeted research agenda

first in village or second in rome though individuals prefer high quality peers there are advantages to being high up in the pecking order within a group in this environment sorting of agents yields an overlapping interval structure in the type space segregation and mixing coexist in a stable equilibrium with transfers this equilibrium corresponds to a competitive equilibrium where agents bid for relative positions and entails less segregation than the efficient allocation more egalitarianism within organizations induces greater segregation across organizations but can improve the allocation efficiency since competition is most intense for intermediate talent effective personnel policies differ systematically between high quality and low quality organizations

a study on long run inefficiency levels of a panel dynamic cost frontier under the framework of forward looking rational expectations abstract this paper aims to provide a theoretical underpinning of the dynamic efficiency model pioneered by ahn s c good d h sickles r c 2000 estimation of long run inefficiency levels a dynamic frontier approach econometric reviews 19 461 492 in the context of a quadratic loss function this paper formulates a multi period forward looking rational expectations model on the evolution of the technical inefficiency level which correctly produces a dynamic panel data model the model is illustrated using panel data of 112 french banks encouraging evidence of superiority in favor of the model is reached substantial cost inefficiency prevails in this industry where the constituent banks are characterized as having volatile adjustment speeds toward their long run steady states the sample banks exhibit increasing returns to scale and product mix economies

the technical efficiency of us banks abstract the paper uses a non parametric frontier approach to measure the technical efficiency of a sample of u s banks the results indicate that these banks could have produced the same level of output with only 70 of the inputs actually used in addition most of this inefficiency is due to pure technical inefficiency wasting inputs rather than scale inefficiency operating at non constant returns to scale finally regression analysis indicates that the technical efficiency of the banks is positively related to size negatively related to product diversity and not at all related to the extent to which branch banking is allowed

consumers willingness to pay for renewable and nuclear energy a comparative analysis between the us and japan abstract this paper examines consumers willingness to pay for nuclear and renewable electricity as two alternatives to fossil fuels for the reduction of greenhouse gas emissions we conduct a choice experiment of consumer stated preferences on the basis of an online survey in four us states and japan after the fukushima nuclear plant accident first the results suggest that us consumers willingness to pay for a 1 decrease in greenhouse gas emissions is 0 31 per month which is similar to the results for the us a decade ago japanese consumers show a slightly lower willingness to pay of 0 26 per month second the average consumer in both countries expresses a negative preference for increases in nuclear power in the fuel mix to a greater extent in japan third renewable energy sources were endorsed by both us and japanese consumers who show a willingness to pay 0 71 and 0 31 per month for a 1 increase in the use of renewable source energy this study also examines the differences in respondents characteristics approximately 60 of the us respondents who did not change their perception concerning the use of nuclear energy subsequent to the fukushima nuclear crisis have almost no preference for variation in nuclear power which is in stark contrast to the japanese respondents opposition to nuclear energy

product line deregulation and the cost structure of us savings and loan associations recent legislative actions restrict thrift powers which were broadened by deregulatory actions in the early 1980s using nationwide data for savings and loans s ls evidence is found that these restrictions may rise intermediation costs for s ls by limiting their ability to exploit economies of scope between mortgage related and other outputs in addition economies of scale for a wide size range of s ls are found evidence is also found to suggest that insolvent s ls have higher costs for the same level of outputs than solvent s ls

economies of superscale in commercial banking most previous studies of scale economies in banking have excluded banks larger than 1 billion in assets thus study by contrast estimates cost functions for the 100 largest us commercial banks hedonic terms are incorporated to correct for the aggregated nature of the call report data available for these banks in addition we attempt to quantify the cost benefit of diversification in the model we estimate efficient bank scale to range from 15 billion to 37 billion in total assets a thousandfold increase over some previous findings these results are supported by comparison of actual average costs as well as by casual historical observation and the level of widespread concern over interstate banking our findings suggest some cost incentive or benefit to expansion or consolidation among large regional banks including interstate expansion or consolidation

hierarchies and entrepreneurship we establish a correlation between the hierarchical structure of a firm and the likelihood of business creation among its former employees using a sample of 16 million observations of swedish workers and a novel proxy for hierarchies based on occupation data conditional on firm size and many other variables employees in firms with more layers are less likely to enter entrepreneurship to become self employed and to switch to another employer the effects of layers are much stronger for business creation than for job switching and they are stronger for entrepreneurship than for self employment we discuss two potential explanations for the distinctive hierarchy effect we find part of the effect could be to be due to preference sorting by employees and part due to employees in firms with fewer layers having a broader range of skills one test showing that the probability of entrepreneurship increases with their prior rank in an organization is consistent with ability sorting and inconsistent with preference sorting

social acceptance of renewable energy innovation an introduction to the concept this paper introduces the special issue on social acceptance of renewable energy innovation it is a collection of best papers presented at an international research conference held in tramelan switzerland in february 2006 while there are ambitious government targets to increase the share of renewable energy in many countries it is increasingly recognized that social acceptance may be a constraining factor in achieving this target this is particularly apparent in the case of wind energy which has become a subject of contested debates in several countries largely due to its visual impact on landscapes this paper introduces three dimensions of social acceptance namely socio political community and market acceptance factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects the third dimension market acceptance has received less attention so far and provides opportunities for further research particularly from management scholars

inequality and the organization of knowledge since the seminal work of lawrence f katz and kevin m murphy 1992 the study of wage inequality has taken as its starting point a neoclassical constant elasticity of substitution production function using as inputs capital and lowand high skill labor this approach assumes that the organization of production is fixed and determined by a particular specification of technology and it ignores both the source of the interaction between workers and the organizational aspects of this interaction these shortcomings are particularly important in light of growing empirical evidence that points first to the importance of decreases in the cost of processing and communicating information and second to the complementarity between organizational change and adjustments in the distribution of wages e g timothy f bresnahan et al 2002 this paper argues that theories that seek to guide empirical research on these areas must put knowledge and information at the center of the analysis of organizations and link the organizational structure with aggregate variables via equilibrium frameworks in garicano and rossi hansberg 2003 we present a model of this kind it determines the patterns of organization as manifested by the communication and specialization patterns and the implied wage structure that result from different costs of acquiring and communicating information here we present a simple variant of this theory that allows us to focus on one of the main aspects of that framework the sorting of agents into teams and the wage and organizational structure that accompanies that sorting we use this simple model to analyze the changes in organization and wages that result from a very specific type of technological change a reduction in the cost of communicating knowledge or information this model allows us to consider the effect on within class wage inequality and the impact of information technology on the creation and form of organizations e g size distribution of hierarchies however because knowledge is exogenously given and agents cannot invest in learning an important margin of the model in garicano and rossi hansberg 2003 is fixed namely the degree of decentralization or the extent to which problems are solved at lower levels that model allows the simultaneous study of the acquisition of knowledge spans of control and matching in equilibrium moreover it goes beyond the current analysis in that it allows for organizations with an unconstrained number of layers and in that it studies two aspects of the impact of information technology communication technology like here and the technology to acquire knowledge or information e g processing power through cheaper database access

a multiproduct cost study of savings and loans this paper investigates the cost structure of savings and loans most studies of financial institutions have failed to take into account the multiproduct nature of these institutions using the multiproduct approach the existence of subadditivity multiproduct global and product specific economies of scale and scope and substitutability between inputs is investigated a translogarithmic cost function is estimated using 1982 data on california savings and loans restrictive functional forms also estimated are rejected standard errors for the statistics calculated are estimated and various statistical tests are conducted previous authors have not calculated standard errors for these statistics no evidence of subadditivity in the industry is found in order to investigate the impact of deregulation on the financial services industry it is necessary to know the cost structure of the industry optimal firm size and product mix can be determined once the structure is known the presence of scale economies would imply that smaller firms or entering firms that operate at a small scale would be at a cost disadvantage compared with larger established firms a finding of economies of scope i e economies of joint production would imply that firms that were specialized would be at a cost disadvantage and that regulations that restrict the outputs a firm is allowed to produce may lead to inefficient production

vertical aspects of male female disparity in the labor market abstract the organization based economy model presented by garicano and rossi hansberg g rh 2004 is used to study the vertical dimensions of male female disparity in the labor market this sheds a new light on the major aspects of the phenomenon

an empirical study of joint production and scale economies in commercial banking this paper utilizes the translog cost function to test the proposition that the bank productionfunction is characterized by jointness the cross section analysis for the years 1973 through 1978 indicates that bank production is in fact characterized by jointness this result calls into question the findings and implications of studies that utilize the assumption of non jointness in production since virtually all of the major bank cost studies employ the assumption of nonjointness the second part of our analysis examines scale economies for the banking firm while allowing for jointness in production our estimates indicate that scale economies characterize bank production at only small bank sizes and that the cost structure of large banks is characterized by diseconomies of scale

technology and the labour market the assessment this article reviews the evidence on how technology will affect labour markets in advanced democracies over the next 10 15 years in addition to assessing evidence on the impact of technology on the aggregate number of jobs we take a wider view to consider how the digital revolution will affect the quality and composition of jobs how and where we work and whether labour is supplied as part of a larger firm or as a self employed micro entrepreneur this assessment further aims to situate the papers covered in this issue of the oxford review of policy within the broader literature

bank regulation and monetary policy the depository institutions deregulation and monetary control act 1980 and the garn st germain depository institutions act 1982 are the two most significant pieces of bank legislation since the 193os their significance stems from the fact that they have sought to roll back a number of the regulations and restrictions imposed on bank activity and competition in the 1933 80 period among the important provisions of these acts are a gradual elimination of regulation q ceilings on time and savings deposits by march 1986 the amelioration of state imposed usury ceilings on loans the nationwide provision of interest bearing transaction type accounts negotiable order of withdrawal now and super now accounts permission for thritts to expand into bank like products such as commercial and industrial loans consumer loans and credit cards and the development of new types of savings accounts such as mmdas l in addition to legislative deregulation we have also witnessed homemade deregulation as banks have sought to exploit often with great success loopholes in the bank holding

the structure of technology in a multioutput branch banking firm we formulate and estimate a multioutput bank s cost function amenable for distinguishing between economies of scale and economies of network density we find significant returns to network density especially for smaller banks diseconomies of scale are found for the larger banks whereas the hypothesis of constant returns to scale could not be rejected for the smaller banks

keep it local and fish friendly social acceptance of hydropower projects in switzerland hydropower is the largest source of renewable electricity in the world but despite being a mature and clean energy technology it has also been the subject of ecological and social conflict literature suggests that the social acceptance of renewable energy can be increased by respecting procedural justice fair participatory planning processes and distributional justice fairly allocating costs and benefits however empirical evidence about how justice considerations are related to the expansion of hydropower is scarce pre existing studies being mostly qualitative in nature we contribute to filling the gap in the current literature by describing in this paper how choice experiments with 1004 swiss residents were undertaken to explore the influence of procedural and distributional justice on acceptance relative to other attributes of hydropower projects we find that while considerations about justice do play a role in decisions to accept respondents in switzerland care most about ecological impacts and secondly about local ownership

consumer preferences for electricity tariffs does proximity matter abstract the introduction of renewable energy sources fosters the transformation to an energy system with distributed generation this alters the relation between consumers and power generation sites as generation and consumption spatially converge it allows for new configurations within the energy sector and provides opportunities for marketing regional energy we empirically investigate consumer preferences for electricity generation in proximity to end users focusing on the proximity of generation and providers and present representative data for germany in a discrete choice experiment a sample of 780 consumer households and 173 adopters of a renewable energy system prosumers chose from a range of different electricity tariffs we estimate the willingness to pay for the following attributes shares of regional generation power providers and electricity mixes we find evidence in favor of regional production but in spite of positive attitudes towards local generation from renewable sources willingness to pay is not responsive to higher shares of regional generation in addition a preference for regional providers exists the results show that renewable energy mixes are preferred particularly a solar and hydro mix adopters state slightly more distinct preferences as compared to consumer households thus we find there is potential for business models offering regionally generated electricity

valuing wetland attributes an application of choice experiments abstract the interest for wetlands is increasing not only because of the possibility of a cost efficient uptake of nutrients but also because wetlands can be designed to provide other services what values that are supplied depend largely on the design there are numerous different design options and different actors may promote different alternatives whether we want to design a wetland for nutrient retention alone or one that also serves other interests policy makers need information about the value of different options conducting a choice experiment we are able to identify attributes that increase and decrease citizens perceived value of wetlands using a random parameter model we find that biodiversity and walking facilities are the two greatest contributors to welfare while a fenced waterline and introduction of crayfish decrease welfare

the german energy transition as a regime shift abstract in this paper i use the resilience framework to interpret the project of transforming the german energy system into a renewable energy sources res based system the so called energiewende as a regime shift this regime shift comprises several transformations which are currently altering the technological political and economic system structure to build my argument i first sketch how technological political and economic developments reduced the resilience of the conventional fossil nuclear energy regime and created a new res regime second i depict recent changes in german public discourse and energy policy as the shift to the res regime third i highlight the challenges involved with increasing the resilience of the res regime in particular sufficient resilience of the electricity transmission grid appears to be crucial for facilitating the transformation of the whole energy system

effects of cheap talk on consumer willingness to pay for golden rice a large body of literature suggests willingness to pay is overstated in hypothetical valuation questions as compared to when actual payment is required recently cheap talk has been proposed to eliminate the potential bias in hypothetical valuation questions cheap talk refers to process of explaining hypothetical bias to individuals prior to asking a valuation question this study explores the effect of cheap talk in a mass mail survey using a conventional value elicitation technique results indicate that cheap talk was effective at reducing willingness to pay for most survey participants however consistent with previous research cheap talk did not reduce willingness to pay for knowledgeable consumers

social acceptance of low carbon energy and associated infrastructures a critical discussion the promotion of low carbon energy and associated infrastructures for tackling climate change is a central task for governments worldwide however public and mainly local opposition to those infrastructures may slow down or even halt that process thus in the last few years a body of research has developed specifically to understand the social acceptance of technologies such as wind turbines or bioenergy plants we argue that the use of acceptance in this literature should be further discussed we contend that using the word acceptance may present some constraints for the theoretical advancement of this area of research and to the implications that may be taken from it to the wider society this is further highlighted through the presentation of findings from surveys conducted with nationally representative samples from the uk and norway which examined their acceptance of and support for new high voltage power lines we conclude by suggesting that the literature on public responses towards low carbon energy and associated infrastructures should be more critical in the conceptualisation of its research agenda become empirically more consistent and transparent and examine other types of relations between people and energy infrastructures besides acceptance or opposition

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

evaluating the cost efficiency of the italian banking system what can be learned from the joint application of parametric and non parametric techniques abstract research on bank efficiency has developed in two separate streams econometric studies and data envelopment analysis a linear programming technique these two branches of literature have developed quickly but separately in this paper these two approaches have been tested on a common panel of 270 italian banks and this has suggested the following i econometric and linear programming results do not differ dramatically when based on the same data and conceptual framework ii when differences arise they can be explained by going back to the intrinsic features of the models moreover some findings on italian banks may be of interest also to the international reader i efficiency scores show a high variance ii the banking system is split in two between northern and southern banks iii there is a direct rather than inverse relationship between productive efficiency and asset quality iv the efficiency of italian banks did not increase over the period 1988 1992

the payoff to skill in the third industrial revolution1 is the third industrial revolution indeed driven by rising payoffs to skill this simple but important question has gone unanswered because conventional models of earnings inequality are based on exceedingly weak measurements of skill by attaching occupational skill measurements to the 1979 2010 current population surveys it becomes possible to adjudicate competing accounts of the changing returns to cognitive creative technical and social skill the well known increase in between occupation inequality is fully explained when such skills are taken into account while returns to schooling prove to be quite stable once correlated changes in workplace skills are parsed out the most important trend however is a precipitous increase in the wage payoff to synthesis critical thinking and related analytic skills the payoff to technical and creative skills often touted in discussions of the third industrial revolution is shown to be less substantial

branching restrictions and banking costs abstract previous research of banking costs has been limited by the choice of the functional form irregularities in the estimated cost functions and a failure to rigorously examine the difference between banks in branching states and banks in unit banking states this paper addresses these shortcomings banks are modelled as three input three output cost minimizing firms a three equation system is estimated using 1985 functional cost analysis data the findings indicate that banks in unit banking states experience diseconomies of scale banks in branching states experience diseconomies of scale at the bank level but economies of scale at the branch level we also find evidence of economies of scope for branch state banks but not for unit state banks

supplier choice and wtp for electricity attributes in an emerging market the role of perceived past experience environmental concern and energy saving behavior abstract this study analyzes customers preferences and their willingness to pay wtp for certain service attributes in an electricity supplier choice context specifically a stated preference choice experiment is conducted in the canary islands residential market where limited competition exists preferences for different electricity suppliers and three level of service attributes are investigated namely supply reliability share of renewable energies and availability of a complementary energy audit service the results might be interpreted as an indication of different aspects new firms need to consider if they plan to enter in the market there is an opportunity for new companies to establish in the market though evidence of brand loyalty to the current company and or significant switching costs are also found especially in the case of older people regarding the estimated wtp several results should be highlighted first customers who have experienced more serious outages in the past tend to show a higher wtp to reduce the outage frequency second highly educated respondents those who state a great concern for the greenhouse gases ghg emissions and those who carry out energy saving actions in their homes exhibit a larger wtp for renewable energies this empirical evidence provides useful information for authorities responsible for energy policy design

modeling preference heterogeneity in stated choice data an analysis for public goods generated by agriculture stated choice models based on the random utility framework are becoming increasingly popular in the applied economics literature the need to account for respondents preference heterogeneity in such models has motivated researchers in agricultural environmental health and transport economics to apply random parameter logit and latent class models in most of the published literature these models incorporate heterogeneity in preferences through the systematic component of utility an alternative approach is to investigate heterogeneity through the random component of utility and covariance heterogeneity models are one means of doing this in this article we compare these alternative ways of incorporating preference heterogeneity in stated choice models and evaluate the sensitivity of estimated welfare measures to which approach is selected we find that a latent class approach fits our data best but all the models perform well in terms of out of sample predictions finally we discuss what criteria a researcher can use to decide which approach is most appropriate for a given data set

the influence of task complexity on consumer choice a latent class model of decision strategy switching the literature indicating that person context and task specific factors cause consumers to utilize different decision strategies has generally failed to affect the specification of choice models used by practitioners and academics alike who still tend to assume an utility maximizing omniscient indefatigable consumer this article 1 introduces decision strategy selection within a maintained compensatory framework into aggregate choice models via latent classes which arise because of task complexity 2 it demonstrates that within an experimental choice task the model reflects changing aggregate preferences as choice complexity changes and as the task progresses the import of these findings for current practice model interpretation and future research needs is examined

preference learning in consecutive experimental auctions this paper explores the origins of the strikingly high price premia paid for new food products in lab valuation exercises our experimental design distinguishes between two explanations of this phenomenon novelty of the experimental experience versus the novelty of the good i e preference learning bids reflect a person s desire to learn how an unfamiliar good fits into their preference set subjects bid in four consecutive experimental auctions for three goods that vary in familiarity candy bars mangos and irradiated meat our results suggest that preference learning is the main source of the high premia and that novelty of the experimental experience does not in itself artificially inflate valuations copyright 2000 oxford university press

whatever the customer wants the customer gets exploring the gap between consumer preferences and default electricity products in germany abstract in liberalized electricity markets residential customers can choose their preferred provider and select among a variety of different electricity products including green power options successful product design and marketing strategies for green electricity may provide electricity providers with a competitive advantage while at the same time contributing to energy policy objectives this requires however a thorough understanding of customer preferences we investigate the relative importance of different product attributes in creating customer value and find that price and electricity mix are the two most important attributes the german electricity customers we surveyed in 2009 expressed an implicit willingness to pay a premium of about 16 for electricity from renewable sources we conclude that consumers are willing to pay a significant price premium for an upgrade from the current default electricity mix in germany to a more environmentally friendly default electricity mix and discuss implications for marketing strategy and energy policy our findings are based on a dataset of 4968 experimental choices made by 414 german residential consumers collected in a stated preference survey

the growing importance of social skills in the labor market the labor market increasingly rewards social skills between 1980 and 2012 jobs requiring high levels of social interaction grew by nearly 12 percentage points as a share of the u s labor force math intensive but less social jobs including many stem occupations shrank by 3 3 percentage points over the same period employment and wage growth were particularly strong for jobs requiring high levels of both math skill and social skills to understand these patterns i develop a model of team production where workers trade tasks to exploit their comparative advantage in the model social skills reduce coordination costs allowing workers to specialize and work together more efficiently the model generates predictions about sorting and the relative returns to skill across occupations which i investigate using data from the nlsy79 and the nlsy97 using a comparable set of skill measures and covariates across survey waves i find that the labor market return to social skills was much greater in the 2000s than in the mid 1980s and 1990s

understanding social acceptance of electricity generation sources abstract social acceptability is a determinant factor in the failure or success of the government s decisions about which electricity generation sources will satisfy the growing demand for energy the main goal of this study was to validate a causal trust acceptability model for electricity generation sources in the model social acceptance of an energy source is directly caused by perceived risk and benefit and also by social trust in regulatory agencies both directly and indirectly through perceived risk and benefit results from a web based survey of chilean university students demonstrated that data for energy sources that are controversial in chilean society fossil fuels hydro and nuclear power fit the hypothesized model whereas data for non conventional renewable energy sources solar wind geothermal and tidal did not perceived benefit had the greatest total effect on acceptability thus emerging as a key predictive factor of social acceptability of controversial electricity generation sources further implications for regulatory agencies are discussed

homogeneity restrictions on the translog cost model a note benston hanweck and humphrey bhh 1 first applied the translog cost model to empirical analyses of depository institutions cost characteristics subsequent studies by benston berger hanweck and humphrey bbhh 2 murray and white 7 gilligan and smirlock 4 and gilligan smirlock and marshall gsm 5 have employed this type of flexible form cost function as a regularity condition the translog cost model should be linearly homogenous in all input prices that is given the following translog cost function

what makes people seal the green power deal customer segmentation based on choice experiment in germany abstract consumers have the power to contribute to creating a more sustainable future by subscribing to green electricity tariffs in order to reach consumers beyond the eco niche identifying the drivers that positively influence the adoption of green electricity is of fundamental importance this paper examines various factors that help to explain the extent to which green electricity subscribers differ from those that display strong preferences towards green electricity but have not yet walked the talk by making use of a latent class segmentation analysis based on choice based conjoint data this paper identifies three groups of potential green electricity adopters with varying degrees of preference for renewable energy findings indicate that socio demographic factors play a marginal role in explaining the differences between green electricity subscribers and potential adopters with the exception that actual adopters tend to be better educated analysis of psychographic and behavioral features reveals that adopters tend to perceive consumer effectiveness to be higher place more trust in science tend to estimate lower prices for green electricity tariffs are willing to pay significantly more for other eco friendly products and are more likely to have recently changed their electricity contract than non adopters policy recommendations associated with these findings are provided

sustainability evaluation of decentralized electricity generation abstract decentralized power generation is gaining significance in liberalized electricity markets an increasing decentralization of power supply is expected to make a particular contribution to climate protection this article investigates the advantages and disadvantages of decentralized electricity generation according to the overall concept of sustainable development on the basis of a hierarchically structured set of sustainability criteria four future scenarios for germany are assessed all of which describe different concepts of electricity supply in the context of the corresponding social and economic developments the scenarios are developed in an explorative way according to the scenario method and the sustainability criteria are established by a discursive method with societal actors the evaluation is carried out by scientific experts by applying an expanded analytic hierarchy process ahp a multicriteria evaluation is conducted that identifies dissent among the experts the results demonstrate that decentralized electricity generation can contribute to climate protection the extent to which it simultaneously guarantees security of supply is still a matter of controversy however experts agree that technical and economic boundary conditions are of major importance in this field in the final section the article discusses the method employed here as well as implications for future decentralized energy supply
