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

separability functional form and regulatory policy in models of interfuel substitution abstract counter intuitive results such as positive own price elasticities have been found in some studies of interfuel substitution this paper examines three possible reasons for this problem first including energy materials in petroleum and coal aggregates is found to contribute to incorrect signs second the mathematical properties of the translog function contribute to concavity violations in contrast the linear logit model of cost shares is found to provide more sensible estimates of own price elasticities across alternative model specifications finally natural gas curtailment policies and environmental regulations are found to be significant factors influencing us industrial fuel demand although omission of these factors does not directly contribute to curvature violations

scale economies and input price elasticities in microfinance institutions abstract we evaluate the efficiency of microfinance institutions mfis using a structural approach which also captures these institutions outreach and sustainability objectives we estimate economies of scale and input price elasticities for lending only and deposit mobilizing mfis using a large sample of high quality panel data the results confirm conjectures that improvements in efficiency can come from the growth or consolidations of mfis as we find substantial increasing returns to scale for all but profitability focused deposit mobilizing mfis our results support the existence of a trade off between outreach and sustainability all inputs are inelastic substitutes but we find differences in own price elasticities in lending only and deposit mobilizing mfis

a model of the financial firm with imperfect asset and deposit elasticities abstract the paper develops an intertemporal model to estimate the production technology of financial firms such as banks price taking is testable in each separate market for assets and liabilities and competitive price taking is a nested special case such tests are applied both to outputs and inputs empirical results for a sample of banks in new york and new jersey indicate that price taking applies only in markets for labor and time deposits in markets for loans demand deposits cash and materials the price taking hypothesis is not accepted

a dynamic analysis of interfuel substitution in u s industrial energy demand using data for 1960 92 to analyze interfuel substitution in the u s industrial sector a dynamic linear logit model is shown to provide superior global properties than a comparable dynamic translog model confirming earlier static results by t j considine 1989 the linear logit model provides a direct unbiased estimate of the rate of dynamic adjustment indicating a median response lag of less than two years excluding fuels used for nonenergy purposes yields larger estimates of the price elasticities for coal and oil and indicates generally greater potential for interfuel substitution than when using aggregate data

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

the economic burden of corporate pension liabilities the pension liabilities reported by firms fall far short of the true economic pension liabilities incurred by firms economic liabilities arise not because firms have mnade a legally binding promise to provide a pension but because workers have deposited savings with their firnms in anticipation of receiving a pension upon retirement emnpirical evidence from labor market and stock market data strongly suggests that these savings flows are made by workers as if they expect a real pension at retirement and beyond the results suggest that corporations have in reality incurred liabilities far in excess of their legal liabilities true economic funding ratios for example have been approximately 70 per cent during the postwar period and have varied widely across pension plans if stock market participants calculate these true pension burdens inaccurately or rely only on reported liabilities then stock valuations are likely to contain large errors

rewriting monetary policy 101 what s the fed s preferred post crisis approach to raising interest rates abstract for many years prior to the global financial crisis the federal open market committee set a target for the federal funds rate and achieved that target through small purchases and sales of securities in the open market in the aftermath of the financial crisis with a superabundant level of reserve balances in the banking system having been created as a result of the federal reserve s large scale asset purchase programs this approach to implementing monetary policy will no longer work this paper provides a primer on the fed s implementation of monetary policy we use the standard textbook model to illustrate why the approach used by the federal reserve before the financial crisis to keep the federal funds rate near the federal open market committee s target will not work in current circumstances and explain the approach that the committee intends to use instead when it decides to begin raising short term interest rates

cost structure and technical change in rural banking abstract using the multi product translog cost function this paper examines the cost structure and technical change occurring within the novel ghanaian rural banks the results of the seemingly unrelated error components model indicate substantial unexploited economies of scale in individual products as well as in overall intermediation there is presence of pairwise complementarity between loans and government securities and between deposits and government securities but absence of pairwise complementarity between loans and deposits overall capital using and labour saving technical change has occurred but efficiency loss in deposit mobilization outweighs the efficiency gains in government securities and lending activities operation of agencies reinforces the overall efficiency loss the rural banks must not be hindered from expanding but in any growth strategy deposit mobilization should take a central position and the cost of operating agencies watched closely

interrelated factor demands from dynamic cost functions an application to the non energy business sector of the uk economy in this paper we propose a dynamic cost function which allows us consistently to derive a set of dynamic interrelated factor demand equations in the general error correction form introduced by anderson and blundell 1982 this paper expands results recently published in urga 1996 it shows that the derivation of an effective underlying cost function allows us to identify the full set of parameters of the underlying process this does not happen in the standard anderson blundell formulation we report an empirical exercise used to model the so called supply side of the london busines school large scale economic model where we estimate both the set of factor demands and the underlying dynamic cost function for the non energy business sector of the uk economy

intermediation and cost determinants of large bank liability composition abstract a translog profit function is estimated for an aggregate of large u s money center banks over 1970 1975 estimates of liability substitution elasticities and own price elasticities of demand are obtained and contrasted with results from earlier partial equilibrium studies statistical analyses led to the rejection of two commonly held propositions in banking 1 that the aggregation of all bank debt to obtain a debt equity ratio is valid and 2 that asset structure can be ignored when liability composition is being determined a mixed full information maximum likelihood estimation technique was used in estimation

do large banks have lower costs new estimates of returns to scale for u s banks this paper presents new fully nonparametric estimates of ray scale and expansion path scale economies for u s banks based on a model of bank costs unlike prior studies that use models with restrictive parametric assumptions or limited samples our methodology uses local polynomial estimators and data on all u s banks over the period 1984 2006 our estimates indicate that as recently as 2006 most u s banks faced increasing returns to scale suggesting that scale economies are a plausible but not necessarily only reason for the growth in average bank size and that the tendency toward increasing scale is likely to continue unless checked by government intervention

firm size and employment determination in dutch manufacturing industries this paper examines whether the determination of employment differs between large and small firms an employment equation is estimated on panel data of 67 35 three digit industries in dutch manufacturing 1974 1986 the conclusions are as follows firstly employment adjustment appears to be faster in small firms than in large ones secondly the elasticity of factor substitution and the real wage elasticity at constant output are nearly the same for large and small firms thirdly the estimated output elasticities suggest constant returns to scale in large firms and increasing returns in small ones finally the number of working hours has less impact on employment in small firms than in large ones

the use of linear logit models for dynamic input demand systems this paper demonstrates that a linear logit model with appropriate constraints can be used to specify a system of cost share equations that satisfy neoclassical economic conditions unlike many other flexible functional forms the logistic function is particularly well suited for incorporating dynamic adjustment mechanisms the empirical results suggest that the use of static models overstates short run own price elasticities and understates the corresponding long run price effects

enjoying the quiet life under deregulation evidence from adjusted lerner indices for u s banks abstract the quiet life hypothesis posits that firms with market power incur inefficiencies rather than reap monopolistic rents we propose a simple adjustment to lerner indices to account for the possibility of forgone rents to test this hypothesis for a large sample of u s commercial banks we find that adjusted lerner indices are significantly larger than conventional lerner indices and trending upward over time instrumental variable regressions reject the quiet life hypothesis for cost inefficiencies however lerner indices adjusted for profit inefficiencies reveal a quiet life among u s banks

the impact of technical change scale effects and forward ordering on u s fiber demands this paper estimates a complete system of input cost shares in u s textile production using time series data and a linear logit specification incorporating the impact of technical change and scale effects on derived demands for natural and manmade fibers the specification accounts for forward ordering dynamics in the textile industry technical change has decreased natural fiber use in u s textile mills in favor of manmade fibers decomposition analysis of economic factors affecting long run use of natural versus manmade fiber indicates that nonprice factors account for 70 of the decline in long run natural fiber use

determinants of corporate pension funding strategy abstract several hypotheses concerning pension funding strategy are tested in a cross sectional regression model on a sample of 255 firms results are consistent with the following explanations 1 finance incentives tax benefits and financial slack for high level funding 2 labor incentives for low level funding and 3 financial statement incentives relating to political costs for high level funding and debt contracting costs for low level funding pension funding strategy appears to be complex involving tradeoffs between funding incentives the nature of these interactions and tradeoffs remains to be clarified through future research

empirical assessment of energy price policies the case for cross price elasticities abstract evaluations of energy price policies are necessarily based on measures of the substitution of energy and non energy inputs facing a variety of substitution elasticities the central question arises which measure would be appropriate apparently for a long time this question has not been at issue allen s elasticities of substitution aes have been the most used measures in applied production analysis this paper s main contribution is an instructive survey of the origin of substitution measures and of the trinity of empirical substitution elasticities aes cross price elasticities and the morishima elasticities of substitution mes with particular emphasis on their interpretations and the perspectives that will be captured by these measures this survey clarifies why classical cross price elasticities are to be preferred for many practical purposes berndt and wood s rev econom stat 57 1975 259 frequently applied data set of us manufacturing is used to illustrate why assessments of energy price policies would be better based on cross price elasticities like the energy price elasticity of capital rather than on aes or mes

a pooled dynamic analysis of interfuel substitution in industrial energy demand by the g 7 countries a dynamic version of considine s 1990 linear logit model is used to obtain theoretically consistent estimates of long run price elasticities from pooled intercountry data on industrial energy consumption this model also provides a rare direct estimate of the important rate of dynamic adjustment revealing a median lag of ten years the long run demands for oil and coal are the most elastic and the strongest channels for interfuel substitution are between oil and natural gas with no significant evidence of complementarity between fuels

entrepreneurship and human development a capability approach abstract we provide a formal model of entrepreneurship in human development the framework is provided by the capabilities approach ca hence we extend not only the conceptualisation of entrepreneurship in development but the reach of the ca into entrepreneurship from a ca view entrepreneurship is not only a production factor or a means to an end as is often taken to be the case by economists but also an end in itself entrepreneurship can be a human functioning and can contribute towards expanding the set of human capabilities through being both a resource and a process our model shows however that entrepreneurship is not automatically a functioning where it is a necessity it stops being a valued functioning the model also shows that even when entrepreneurship is valued entrepreneurs may often not match their ideas with suitable opportunities policy implications are discussed

modelling energy and non energy substitution a brief survey of elasticities estimating the degree of substitution between energy and non energy inputs is the key for any evaluation of environmental and energy policies yet given the variety of substitution elasticities the central question arises as to which measure would be most appropriate apparently allen s elasticities of substitution have been the most used measures in applied production analysis in line with frondel 2004 this paper argues that cross price elasticities are preferable for many practical purposes this conclusion is based on a survey of classical substitution measures such as those from allen morishima and mcfadden the survey highlights the fact that cross price elasticities are their essential ingredients

dynamic factor demands and the effects of energy price shocks a dynamic model is used to understand how sharp changes in energy prices affect investment behavior employment and energy use the authors discuss the theory behind their model selection model specifications estimation methods and data list parameter estimates and elasticities for the selected model and describe the simulations they conclude that 1 the data strongly reject the hypothesis of constant returns to scale within their specification of aggregate production 2 the data indicate adjustment costs on labor are small and 3 their results help reconcile some of the conflicting estimates of energy demand elasticities appearing in recent literature 23 references 3 figures 3 tables

testing dynamic specification of factor demand equations for u s manufacturing this paper addresses the question of dynamic specification of empirical models of factor demand for annual u s manufacturing data from 1947 to 1981 frequently used models that treat a subset of factors as variable are shown to be misspecified an error correction model is considered as an alternative specification this model is shown to dominate several more parsimonious models in several respects however like the other models considered the error correction model is unable to generate satisfactory estimates of long run elasticities the issue of dynamic specification remains unresolved copyright 1992 by mit press

returns to scale and input substitution for large u s banks the united states commercial banking industry has experienced significant changes in recent years the recent wave of mergers and the near term prospects of interstate banking suggests that the industry is moving toward much larger average banking organizations rhoades 1985 will a more concentrated banking industry result in lower costs due to scale economies we address this question by examining the cost function for large banks numerous studies of economies of scale in banking exist generally tracing their roots to the classic papers by benston 1965 and bell and murphy 1968 a good review of the most recent studies can be found in clark 1988 the majority of the papers uses samples of smaller banks that is under 1 billion in deposits finding generally that economies of scale are quickly exhausted and that further increases in bank size occur at constant or possibly increasing cost the extrapolation of previous findings for samples of smaller banks to large banks may be problematic especially in the current environment first large banks service a different mix of markets and customers than small banks suggesting that large and small banks probably face different cost structures second the process of deregulation may have rendered the results of prior studies moot since the data pertain to periods before significant deregulation since we

constructing confidence intervals using the bootstrap an application to a multi product cost function a multi product cost function system is estimated for 387 banks in states that allow branch banking the bootstrap resampling method is used to construct confidence intervals for marginal costs output cost elasticities economies of scale and scope and allen elasticities of substitution confidence intervals for these measures are usually constructed using a first order variance approximation under a normality assumption but such confidence intervals are inexact if the measures are not normally distributed or the variance approximations are imprecise we find that the bootstrap standard error estimates can differ significantly from the usual estimates furthermore we use the bootstrap to expand the analysis of cost function regularity properties copyright 1990 by mit press

dynamic translog and linear logit models a factor demand analysis of interfuel substitution in us industrial energy demand abstract we compare and contrast two popular dynamic flexible functional forms for cost functions the translog and the logit j bus econ stat 8 1990 347 353 using data on us industrial energy demand from 1960 to 1992 which has been analysed by previous studies energy econ 11 1989 89 94 appl econ 21 1989 931 945 j bus econ stat 13 1995 459 465 we show the crucial role played by different dynamic formulations of the translog in this analysis of factor demands with respect to rates of dynamic adjustment and substitution possibilities we conclude that the poor performance of the dynamic translog relative to the dynamic logit cannot be explained solely by dynamic model mis specification or the inclusion of price unresponsive non energy fuel use data our most robust empirical result is that coal and oil are substitutes

banks free banks and u s economic growth the federalist financial revolution may have jump started the u s economy into modern growth but the free banking system 1837 1862 did not play a direct role in sustaining it despite lowering entry barriers and extending banking into developing regions we find in county level data that free banks had little or no effect on growth the result is not just a symptom of the era as state chartered banks seem to have strong and positive effects on manufacturing and urbanization jel g21 n21 o43

politicians and banks political influences on government owned banks in emerging markets abstract government ownership of banks is very common in countries other than the united states this paper provides cross country bank level empirical evidence about political influences on these banks it shows that government owned banks increase their lending in election years relative to private banks this effect is robust to controlling for country specific macroeconomic and institutional factors as well as bank specific factors the increase in lending is about 11 of a government owned bank s total loan portfolio or about 0 5 of the median country s gdp per election per government owned bank

interrelated factor demands for manufacturing a dynamic translog cost function approach abstract in this paper we report the results of estimating a joint model for labour capital and energy using the transcendental logarithmic cost function of christensen jorgenson and lau 1973 this allows us to determine both the own price and cross elasticities of substitution between labour capital and energy we combine a model of factor shares with a dynamic adjustment process for each factor we also impose on the cross equation restrictions necessary to provide additivity homogeneity and symmetry since the covariance matrix in systems of share relationships is singular we follow the suggestions of anderson and blundell 1982 and employ a mullivariate error corrrection model the results suggest that additivity symmetry and homogeneity restrictions do hold and that there are short run increasing returns to scale

how do banks adjust to changing input prices a dynamic analysis of u s commercial banks before and after the crisis abstract the 2000 2013 period was characterized by substantial regulatory monetary and technological change especially after the onset of the global financial crisis this study assesses the total impact of these policy shifts and technological changes on u s commercial banks short run and long run substitution elasticities an endogenous break test divides the sample into a pre crisis period and a post crisis period during the former period banks inputs tend to be inelastic substitutes after the onset of the crisis particularly the long run substitutability of most input factors decreases to even lower levels due to changes in both cost technology and economic conditions at the same time banks response to input price changes becomes more sluggish hence especially after the onset of the crisis banks have little flexibility regarding input factor usage and are thus sensitive to input price changes from a cost perspective

the empirical assessment of technology differences comparing the comparable this paper compares technologies across space and time on the basis of factual and counterfactual substitution elasticities and argues that differences in estimated substitution elasticities should be decomposed into two counterfactual components while the first component is designed to indicate how the ease of substitution is altered by varied economic circumstances the second addresses the question of how technologies would compare under genuinely comparable situations this argument is illustrated by the example of energy price elasticities of capital before and after the oil crisis of the early 1970s

core deposits and physical capital a reexamination of bank scale economies and efficiency with quasi fixed inputs this paper compares measures of bank production efficiency assuming all bank inputs are completely variable with measures obtained from specifications which take account of the quasi fixed nature of core deposits and bank physical capital and the treatment of certain deposits as outputs the empirical results imply that scale economy measures vary substantially for small to medium sized banks whereas those for the largest banks are fairly robust to the different specifications estimates of economies of scope were found to be invariant to different input output specifications whereas efficiency measures varied significantly with changes in the specification of the cost function and with the definition of outputs and inputs copyright 1995 by ohio state university press
