accession of the czech republic hungary and poland to the european union impacts on agricultural markets we analyse the consequences on agricultural markets of enlargement of the european union eu to include the czech republic hungary and poland we produce a market outlook up to 2010 for two enlargement scenarios assuming different policy restrictions on grain and dairy production in the acceding countries accession of the three central and eastern european countries ceecs leads to a permanent but moderate decrease in eu prices for most commodities in the three acceding ceecs domestic prices increase drastically final consumption of agricultural products decreases in most instances while production increases higher domestic prices in the ceecs reduce exports of most commodities to non union countries consequently excess supplies are placed in stocks or exported to the original 15 member countries supply management mechanisms in the dairy and grain sectors would reduce the build up of surpluses in the new member states but limit their ability to take advantage of the expanded market accession of the three ceecs would increase the cap budget over its proposed maximum if area payments are extended to incoming crop producers

representing the influence of multiple social interactions on monthly tourism participation behavior abstract based on japanese panel data derived from 12 monthly waves and 1253 questionnaires the study examines the impact of social interactions on tourism participation social interactions are classified into three types namely endogenous exogenous and correlated effects it is empirically confirmed that endogenous social effects have significant influences on tourism participation behavior for example it is found that interactions with people of the same income groups an example of endogenous social effects are generally significant across most months of the year however it is worth noting that endogenous social effects will be overestimated if the correlated social effect is not taken into account the results suggest that social multiplier effects can be discerned that have potential implications for promotion and management of tourism participation rates

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

the tale of two research communities the diffusion of research on productive efficiency abstract the field of theoretical and applied efficiency analysis is pursued both by economists and people from operational research and management science each group tends to cite a different paper as the seminal one recent availability of extensive electronically accessible databases of journal articles makes studies of the diffusion of papers through citations possible research strands inspired by the seminal paper within economics are identified and followed by citation analysis during the 20 year period before the operations research paper was published the first decade of the operations research paper is studied in a similar way and emerging differences in diffusion patterns are pointed out main factors influencing citations apart from the quality of the research contribution are reputation of journal reputation of author number of close followers colleagues cadres of proteges ph d students and extent of network invisible college such factors are revealed by the citing papers in spite of increasing cross contacts between economics and operations research the last decades co citation analysis reveals a relative constant tendency to stick to own camp references

efficiency analysis in banking firms an international comparison abstract the intensive process of financial european integration together with the profound transformation and deregulation that has taken place in the spanish banking system justifies the evaluation of its efficiency in comparison with that of other banking systems in this context the aim of this study is to analyze the productivity efficiency and differences in technology of several banking systems using a non parametric approach together with the malmquist index we compare the efficiency productivity and differences in technology of different european and us banking systems for the year 1992

an index number approach to measuring bank efficiency an application to mergers abstract the current wave of bank mergers has resulted in an interest in the measurement of consequent efficiencies previous studies have generally focused on the measurement of merger induced cost efficiencies in this paper we turn to the production side and examine the change in relative productivity arising from bank mergers after deriving our superlative multilateral productivity index we compute the indexes for our entire sample of banks approximately 2 000 banks in each of the years 1984 1988 and for a cohort of 160 banks that merged in 1986 we find that acquiring banks achieve no gains in efficiency and this finding supports those of other studies on the other hand we find that our acquiring banks are consistently more productive than the sample as a whole by implication if mergers can be generally characterized as the acquisition by a relatively more productive bank of a relatively less productive bank an empirically valid supposition then industry performance should improve as a result of these mergers

bias in malmquist index and cost function productivity measurement in banking this paper illustrates how many prior studies ofproductivity growth in the banking industry have been overstated this occurs with both dea malmquist index and parametric stochastic cost frontier productivity measurement approaches the problem is not due to the technique used but in how it is applied it is easiest to see in the banking industry due the nature ofthe data available the bias is eliminated when all outputs and inputs are included in the analysis ensuring that the balance sheet restriction is met although simple in concept this problem and its solution have so far been neglected in the literature r 2002 elsevier science b v all rights reserved

identifying determinants of branch performances in agricultural bank of china a spatial econometric approach this paper identifies determinants of branches performances in agricultural bank of china using the spatial econometric approach studies on changes of spatial patterns of a financial industry are scarce especially at the branch level this paper is the first attempt to take spatial interdependence and urbanisation effects into account to investigate the determinants of china s bank branches performances from 1997 to 2011 we have chosen the world s 10th largest bank the agricultural bank of china because it discloses the most complete panel data of all empirical evidence indicates that spatial effects and urbanisation have large statistically significant impacts on branches performances it highly and positively corresponds to tertiary industry output domestic consumption and urbanisation this signals that the abc has evolved from a state owned specialised bank to a listed commercial bank

demand for rural tourism the effects of quality and information the development of rural tourism is regarded as a promising diversification strategy especially for lagging and mountainous areas of the european union research concerning the demand and or supply of rural tourism services has been limited within the agricultural economics domain despite the significance attached to rural tourism by various rural development policy measures and initiatives the article examines the expenditure behavior of rural tourists within a framework of demand for composite heterogeneous goods the proposed framework captures the quality of the tourism experience as the commodity s unit value a quantifiable economic variable examines its effects on expenditures and allows for the estimation of elasticity in prices regarding expenditure and quantity empirical analysis is facilitated by a survey recording the expenditure behavior of 465 tourists in two rural and lagging areas of greece the quality of the tourism experience is significantly and positively affected by the income the source from which information about the trip is retrieved internet newspapers as well as general press and special travel press and by the amount of information sought by the consumer prior to the trip in turn the quality of the tourism experience is the major endogenous factor that positively influences expenditures for rural tourism further research is needed before evidence provided in this work can be used to draw policy conclusions and recommendations

determinants of pension plan fees in spain pension plans and funds represent a substantial part of the welfare systems in both europe and spain one of the most important factors in the choice of a plan or fund is the performance it obtains in view of the influence that fees have on performance the objective of this study is to analyse the variables that determine the management and custodial fees of individual pension plans the spanish market for pension plans and funds sets legal caps on these fees and at the same time the majority of them are commercialized and managed by financial institutions which can in turn generate a conflict of interests in this article we estimate models with censured variables and our findings show how the average investment per plan the legal status and the size of the management company to which the plan belongs and the style of the plan are all relevant determinants of the management fee in turn the custodial fee is determined by the legal status of the custodial company the size the return and the type

demographic change tourism expenditure and life cycle behaviour abstract the paper explores how demographic changes in human populations may impact on tourism decision making of households over their life cycle by means of hurdle models the study focuses respectively on the decision to travel domestically or abroad and investigates if statistically significant differences exist as to the impact of age and cohort on the decision to travel and tourism expenditure using a vast dataset on italian household expenditures over the period 1997 2007 the empirical results show that demographic aspects do have a strong effect on the tourism behaviour of families and that cohort and age effects act differently on the decision of households to make a trip and on how much they spend on tourism age has a negative effect on the desire to travel but a positive effect on tourism expenditure on the other hand older cohorts are inclined to travel but they have a low propensity to spend on tourism relevant differences in income elasticity along the life cycle of households have also been found finally age and cohort aspects have a different effect on the decision as to whether to travel nationally or internationally

the takeover deterrent effect of open market share repurchases this paper examines whether open market share repurchases deter takeovers we model pre repurchase takeover probability as a latent variable and examine its impact on the firm s decision to repurchase shares given specification tests reject the tobit model we turn to the censored quantile regression method of powell 1986 journal of econometrics 32 143 155 we find a significantly positive relation between open market share repurchases and takeover probability and we reconcile empirical findings in previous studies that contradict predictions repurchase activity is inversely related to firm size consistent with smaller firms having greater information asymmetry and is related to temporary but not permanent cash flows

technical and environmental efficiencies and best management practices in agriculture an input distance function idf is estimated to empirically evaluate and analyse the technical and environmental efficiencies of 210 farms located in the chaudiere watershed quebec where water quality problems are particularly acute because of the production of undesirable outputs that are jointly produced with agricultural products the true idf is approximated by a flexible translog functional form estimated using a full information maximum likelihood method technical and environmental efficiencies are disaggregated across farms and account for spatial variations our results show that there is a significant correlation between the two efficiencies the idf is used to compute the cumulative malmquist productivity index and the fisher index the two indices are used to measure changes in technology profitability efficiency and productivity in response to the adoption of two selected best management practices bmps whose objective is to reduce water pollution we found significant differences acro

bayesian analysis of the two part model with endogeneity application to health care expenditure this paper studies the effect of managed care on medical expenditure using a model in which the insurance status is assumed to be endogenous insurance plan choice is modeled through the multinomial probit model the medical expenditure variable the outcome of interest has a significant proportion of zeros that are handled using the two part model extended to handle endogenous insurance the estimation approach is bayesian based on the gibbs sampler the model is applied to a sample of 20 460 individuals obtained from the medical expenditure panel survey the results provide substantial evidence of selectivity copyright 2006 john wiley sons ltd

the impact of changes in household vacation expenditures on the travel and hospitality industries two large tourism industries travel and hospitality are strongly affected by changes in household demand for vacations in recent years rising income and declining prices per unit of quality have led to changes in patterns of household vacation consumption to understand the impact of these changes on the travel and hospitality industries we develop a theoretical model distinguishing between travel and on site expenditures and apply it to israeli data we find that under certain circumstances the changes in income and prices are responsible for a shift toward multiple short vacations this trend can be a boon to the travel industry but a disadvantage for the hospitality industry both industries are expected to face a rise in the demand for high quality products

modelling r d expenditure data with zero observations two equation model this article attempts to analyse the determinants of firms research and development r d expenditures in korea by considering the business environment after the economic crisis in 1997 in addition to take into account zero r d expenditure this article employed a two equation model unlike models used in other studies this method incorporates a two level decision structure the participation decision and the decision on the amount to spend once the issue of participation has been decided according to the estimation results while the proposition that larger firms are more active in r d is true the proposition that firms that possess market power are more active in r d is not true for korea technical cooperation among korean firms seems to be less active than in other countries in addition the results indicate that foreign investment stimulates the firms r d expenditure furthermore a number of factors were found to play a role in promoting firms r d activities the external conditions of the f

dea and sfa research on the efficiency of microfinance institutions a meta analysis microfinance has played a key role in the fight against exclusion and the promotion of entrepreneurship in developing countries an important question today is how to increase the reach and profitability of microfinance in a context where subsidies are withdrawing to promote the viability and sustainability of microfinance institutions mfis efficiency analysis has found favor in this context and has attracted growing interest among professionals partners and researchers abundant empirical work has been conducted over the last ten years on this subject in very different contexts and with different methodologies the purpose of this article is to provide a meta regression analysis on parametric and nonparametric estimations of mean technical efficiency mte in microfinance using a data set of 262 observations from 38 studies the results show that in the microfinance industry mte scores have increased over time however with an mte rate of approximately 61 1 there is room for improving efficiency mfis use more resources than necessary for the results achieved in terms of outreach and revenue generated our results show heterogeneity of mte according to the methodological approach of the studies studies with a larger number of variables inputs and outputs produced higher mte scores than did those with a smaller number of variables studies using the variable returns to scale assumption resulted in higher mte scores than those using constant returns to scale in addition those with a production approach had higher mtes than did those using the intermediation approach while studies of a large number of mfis had lower scores than did those involving a small sample size moreover research estimating social efficiency generated lower mtes compared to those estimating financial efficiency studies using data from african mfis obtained lower mtes than did those on mfis in latin america and mena which confirms the poor performance of african microfinance

consumer choice and competition policy a study of uk energy markets consumer choice is increasingly recognised as a crucial factor in competition policy to illustrate the implications of such choice we present an investment model of the switching choice in the uk residential natural gas market and examine responses to a specially commissioned survey of nearly seven hundred consumers identifying search and switching costs through an assessment of the savings which consumers say they require to switch supplier together with an evaluation of consumer switching behaviour we deduce that the incumbent retained considerable market power suggesting that some continued regulation may be necessary

technical efficiency and scale efficiency in the italian banking sector a non parametric approach measures of technical and scale efficiencies are derived in the italian banking industries by implementing non parametric data envelopment analysis on a cross section of 174 italian banks taken in 1991 the methodology of the parametric and non parametric approaches to measure efficiency are discussed the existence of both technical and allocative efficiency is established this result is robust to modifications in the specification of inputs and outputs suggested by the intermediation approach and by the asset approach in implementing both the intermediation and the asset approach the traditional specification of inputs is modified to allow an explicit role for financial capital in addition regression analysis is used on a bank specific measure of inefficiency to investigate determinants of banks efficiency efficiency is best explained by productive specialization size and to a lesser extent by location

university library benchmarking an international comparison using dea abstract this paper proposes a framework for assessing the technical efficiency of 118 university libraries from australia austria canada germany switzerland and the united states the flexible non parametric approach of data envelopment analysis has been chosen to analyse the performance differentials of university libraries we also investigate whether the institutional settings affect the degree of library efficiency the findings of the intercountry efficiency comparison revealed that almost one third of the university libraries are technically efficient using environment specific frontiers to distinguish differences in managerial efficiency from differences in environmental efficiency we found considerable differences in technical efficiency between european and non european university libraries however as regards the environmental setting the non european best practice frontier outperforms the european best practice frontier

industry performance and structural efficiency measures solutions to problems in firm models abstract it is shown that average unit structural efficiency measures do not measure the level of technical efficiency in a firm model of an industry alternative structural efficiency measures generalized to multiple input and multiple output technologies are presented as a solution to the problem of how to estimate the relative performance of an industry as a whole where reallocation of inputs across firms is not feasible compared to existing measures the proposed measures require additional information therefore the linear programming dea models needed to obtain this information are presented this non parametric approach to relative efficiency measurement is also used to obtain economic efficiency estimates for an industry as a whole without imposing a priori restrictions on the relative input and output weights

a fractionally integrated autoregressive moving average approach to forecasting tourism demand the primary aim of this paper is to incorporate fractionally integrated arma p d q arfima models into tourism forecasting and to compare the accuracy of forecasts with those obtained by previous studies the models are estimated using the volume of monthly international tourist arrivals in singapore empirical findings demonstrate the evidence that the approach we propose generates relatively lower sample mean absolute percentage errors mapes this study also deals with the volatile data faced by a forecaster we use the asian financial crisis and the september 11 event as examples of economic and political shocks with respect to the objective of shaving the coefficient mape forecasts based on the selected arfima models dominate convincingly

income and the substitution pattern between domestic and international tourism demand this article analyses the role of income in the decision of participating in the tourism demand within 1 year the tourists who are participating can travel to domestic destinations only abroad destinations only or to both of them such a substitution pattern is modelled using a bivariate probit model the analysis is carried out to the regional level using a survey conducted in 15 european eu 15 countries in addition to the traditional socioeconomic variables the analysis adds new variables to the outbound tourism demand modelling such as the attributes of the place of residence the results show that tourism demand is income elastic however there are marked differences in the income elasticities of the probabilities of travelling domestically or abroad above certain income threshold the substitution pattern between destinations takes part the probability of travelling domestically only remains constant whereas the probability of travelling abroad keeps growing additionally the article prov

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

efficiency measures and productivity indexes in the context of university library benchmarking data envelopment analysis dea has attracted considerable attention during the last few decades as an intuitively clear method for performance assessment theoretical developments have taken turns with empirical efficiency studies in this paper we empirically analyse performance differences across university libraries from different countries from a cross section and a longitudinal perspective we use the malmquist index approach to disentangle environmental efficiency from technical efficiency te to highlight performance differences eventually induced by environmental factors beyond the control of library management as well as to decompose productivity changes over time into changes in te and changes in technology in our cross section analysis we found that north american na libraries are more productive at higher input levels than the european libraries from germany and austria at which we looked in this contribution moreover the largest na libraries are still able to improve performance as t

seminonparametric estimation of conditionally constrained heterogeneous processes asset pricing applications the overidentifying restrictions of the intertemporal capital asset pricing model are usually rejected when tested using data on consumption growth and asset returns particu larly when additively separable constant relative risk utility is attributed to the representa tive agent this article investigates the extent to which specification error can explain these rejections the empirical strategy is limited information maximum likelihood in conjunc tion with seminonparametric expanding parameter space representations for both the law of motion and utility we find that consumption growth and asset returns display conditional heterogeneity but this fact does not account for rejection of the overidentifying restrictions as might be anticipated from the work of hansen singleton and others using generalized method of moments methods we also find that expansion of the parameter space in the direction of nonseparable utility causes the overidentifying restrictions to be accepted our estimation strategy provides information on the manner in which the restrictions distort the law of motion in particular imposition of additively separable constant relative risk aversion utility causes the conditional variance of consumption growth to be overpredicted the conditional covariance of asset returns with consumption growth to be overpredicted and an equity premium imposition of nonseparable seminon parametric utility causes distortion in these same directions though the distortions are much smaller which is consistent with the outcomes of the tests of the restrictions

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

welfare impacts of indian apple trade policies in april 2000 india eliminated the quantitative import restriction of apples and instituted a trade barrier in the form of lower ad valorem tariffs this study examines the impacts of indian trade policies on the apple market by reviewing the government policies discussing mathematical and graphical analyses of trade policies presenting estimated equations of demand supply and excess supply and providing solutions of prices quantities and welfare impacts under autarky free trade and tariff regimes given the total population of more than one billion and a vast middle income population and economic reforms and resulting income growth india has a considerable potential to increase its apple consumption our study shows that under free trade india will consume 3008 thousand metric tonnes tmt of apples of which 2237 tmt will be imported also free trade will increase the total welfare by rs 29 512 million these large gains suggest that india should liberalize apple import barriers and move to

understanding tourists economizing strategies during the global economic crisis abstract this paper explores how tourists from 165 regions of eu 27 countries cut back their tourism expenditure during the global economic crisis in 2009 cutbacks in tourism expenditure are divided into two mutually related decisions firstly whether or not the tourists decided to cut back on tourism expenditure because of the crisis and second which of six options they employed as their cut back strategy fewer holidays reduced length of stay cheaper means of transport cheaper accommodation travel closer to home or change the period of travel the econometric model used to address these kinds of simultaneous decisions is an adaptation of the heckman model within a generalized structural equations modelling approach this methodology controls for sample selection bias and correlations between equations this paper highlights patterns in cutback decisions that are associated with the socioeconomic characteristics of the household and the climate in the country of origin

the effects of shared atm networks on the efficiency of turkish banks this study investigates whether forming shared atm networks has yielded positive benefits for banks in turkey by increasing their productive efficiency using a data envelopment analysis dea approach pure technical and scale efficiency scores of turkish banks are estimated and analysed for the period 2000 2003 the results suggest that although it is possible to realize positive effects through atm sharing arrangements there are multiple factors that determine which banks realize such benefits the geographical distribution of shared atms between urban and rural markets and the level of competition between banks within urban areas are shown to be important determinants of differences in bank efficiency this discrepancy between the gains associated with atm sharing may have important implications concerning the adoption and sharing of new technology by banks in developing countries

the effects of mfa quota elimination on indian fibre markets this article examines the effects of multi fibre arrangement mfa quota elimination on indian fibre market the partial equilibrium indian fibre model was developed using a theoretically consistent framework and incorporated regional supply response substitutability between cotton and man made fibres and appropriate linkage between cotton and textile sectors baseline projections were developed for supply demand and prices of cotton man made fibres and textiles under a set of exogenous assumptions the effects of mfa textile quota eliminations were introduced into the model by conducting three scenarios i e increasing textile exports by 10 20 and 30 from the baseline level the results suggest that on an average cotton imports rise by 4 8 annually while the man made fibre exports from india decline with the opening of textile markets in the developed countries the higher domestic cotton prices encourage acreage expansion in cotton in all the three regions in india but not enough to meet risi

tourism participation and expenditure by spanish households the effects of the economic crisis and unemployment abstract this paper examines household tourism participation decisions and tourism expenditure across the business cycle microdata is used from the spanish household budget survey for the years 2006 2010 facilitating an analysis of the consequences of the economic crisis and unemployment on tourism consumption decisions by households by estimating a heckman model the effects of households socioeconomic determinants on participation and expenditure decisions can be identified taking the year 2008 the beginning of the crisis as a reference the stability of the tourism expenditure model is tested identifying variables whose effects alter in times of crisis one important aspect of the study is how household unemployment affects tourism participation and expenditure decisions the effect of unemployment takes into account whether it is the main breadwinner his or her spouse or another member of the household who is unemployed concentrating on those households whose main breadwinner was employed at the time an analysis is also made of how job insecurity affects tourism consumption decisions from the results the unemployment variables can be seen to have a significant explanatory power suggesting that unemployment information does help to explain the evolution of tourism expenditure across the business cycle

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

an analysis of households appraisal of their budget constraints for potential participation in tourism abstract this paper examines the importance of households budget constraints as a barrier to participation in tourism for this purpose a sample of spanish households drawn from the european community household panel was analysed this survey gathers data on the economic and socio demographic situation of all adult household members more specifically it includes a question on each household s capacity to afford a week s yearly holiday the aim of this question is to assess whether households have sufficient financial resources to participate in tourism the results of the analysis demonstrate that budget constraints on tourist travel are binding for a significant percentage of spanish households the results also show that this type of constraint is not only conditioned by the level of income but by a more complex appraisal that also includes other financial variables such as households saving capacity or the unemployment status of its members furthermore non financial variables such as the level of education age and barriers associated with poor health status all help to determine the degree of importance with which households perceive their budget constraints

determinants of vacation travel among israeli seniors theory and evidence this study investigates determinants of vacation travel among seniors a consumer choice model is developed that incorporates effects of retirement and health on available leisure time and effects of age and education on disposable income the empirical implications of the model depend on leisure and income patterns that in turn determine if time and budget constraints are binding the model is illustrated using data collected from israeli seniors results confirm theoretical predictions regarding the changing effectiveness of constraints as seniors grow older

cross country comparisons of efficiency evidence from the uk and italian investment firms abstract this paper compares and reconciles two new methods for cross country comparisons of the cost efficiency of uk and italian investment firms over the period 1995 1998 it employs four different specifications of the stochastic frontier methodology using a translog cost function in order to measure x efficiency the traditional common frontier reveals that italian investment firms are nearly as efficient as uk firms to overcome traditional limitations two methods are used in this paper they provide consistent results the first method shows differences between the efficiency of the two countries by incorporating environmental variables into the cross country common frontier the second method shows differences in the efficiency of the domestic versus foreign investment firms in the two countries by testing the ability to monitor and control on a cross border basis finally to identify investment firms that are both cost and profit efficient we undertake a profitability test

forecasting tourism demand with arma based methods abstract the forecast of tourism volume in the form of arrivals is of special importance for tourism and other hospitality industries because it is an indicator of future demand thereby providing basic information for subsequent planning and policy making in this paper three univariate arma based models are applied to tourism demand as represented by the number of world wide visitors to hong kong japan korea taiwan singapore thailand the philippines australia and new zealand the study employs both monthly and quarterly time series generated from nine principal tourist destinations in asian pacific region in the forecasting exercise to ensure the reliability of the forecasting evaluation forecasting performance based on disaggregated arrival series in a particular destination is examined as well the general impression is that the arma based models perform very well and in some cases the magnitude of mean absolute percentage error is lower than 2 level

banking efficiency in the nordic countries abstract evidence of the relative competitiveness of the banking industries in three nordic countries is provided by applying data envelopment analysis of productivity on the national and the pooled data sets the analysis produces a detailed account of how well banks from different countries and different sizes may be prepared to meet the more intense competition of a common european banking market

dea ar profit ratios and sensitivity of 100 large u s banks abstract several important dea ar concepts were applied here to banking for the first time this application includes classification sensitivity uniqueness linked cones lcs and profit ratios notably large bank behavior seems to be explained better by profit ratios than by relative efficiency measures of dea efficiency ar efficiency and lc profit ratios were made for a bank panel of the u s s 100 largest banks in asset size from 1986 to 1991 high levels of inefficiency were found as in previous studies classification of the dea efficiency measures identified the inefficient dmus with some positive primal slacks sensitivity analysis of the dea efficiency measures showed that the extreme efficient classification was generally relatively insensitive to errors in the data the ars eliminated i 44 to 60 of the dea extreme efficient dmus and ii all of the banks with unprofitable actual profit ratios some statistical analyses highlight the superiority of the lc profit ratios relative to the ar efficiency measures

identifying price linkages a review of the literature and an application to the world market of cotton this paper reviews the literature of price linkages and examines the degree to which cotton prices are linked it also tests whether such linkages have improved over the last decade it concludes that the degree of linkage has improved over the last decade while the main source of this improvement appears to be a result of short run price transmission and to a lesser extent long run co movement

a micro econometric analysis of vacation behaviour we present a micro econometric limited dependent variable model which simultaneously explains the decision whether to go on vacation or not the choice of destination and the decision on the level of the vacation expenditures the model has been estimated on the basis of a cross section of dutch households we find a striking difference in income elasticity between domestic vacations and vacations abroad and a large impact of owning certain durables such as a boat on the choice of destination to illustrate the potential of the model some simulations are performed

is there a single frontier in a single european banking market abstract this paper attempts to estimate comparable efficiency scores for european banks operating in the single market in the eu using a data set of more than 5000 large commercial banks from all major european banking markets over the period 1993 2004 the application of meta frontiers enables us to assess the existence of a single and integrated european banking market we find evidence in favor of a single european banking market characterized by cost and profit meta frontiers however compared to the meta frontier estimations pooled frontier estimations tend to underestimate efficiency levels and correlate poorly with country specific frontier efficiency ranks

intertemporal efficiency analysis of sales teams of a bank stochastic semi nonparametric approach abstract the primary role of a bank branch is evolving from a service provider towards a sales channel previous branch level studies of sales efficiency consider a static setting of a single time period ignoring the stochastic nature of sales outcomes in this paper we examine efficiency and performance of sales teams in a bank branch network over time taking into account the changing demand and operational conditions as well as random disturbances the intertemporal sales frontier is estimated from the panel of monthly data over the years 2007 2010 using the stochastic semi nonparametric envelopment of data stoned method the efficiency scores of sales teams and the trajectories of performance over time allow managers and the sales force to learn from past events and to develop the managerial and work practices across the network while this study focuses on the case of a specific bank some of the innovative features of our approach are applicable to sales efficiency assessment in other banks and financial institutions as well as other network based sales organizations

elasticities in aids models in the literature a variety of approaches have been used to calculate demand elasticities in almost ideal demand system aids models of demand it is common to estimate the linear approximate almost ideal demand system la aids instead of the aids when the la aids is estimated all of the previously reported approaches to compute elasticities are theoretically incorrect this paper presents correct formulas for la aids elasticities and illustrates the potential errors from using incorrect computing the almost ideal demand system aids of deaton and muellbauer 1980a b has become popular in recent years anderson and blundell blanciforti and green 1983a b blanciforti green and king chalfant eales and unnevehr fujii khaled and mak fulponi heien and willett murray parsons ray a variety of approaches to computing elasticities has been used and some of the approaches may lead to significant errors this paper clarifies the differences between alternative approaches to estimating demand elasticities in aids models

nonparametric and semiparametric methods for economic research abstract developments in the vast and growing literatures on nonparametric and semiparametric statistical estimation are reviewed the emphasis is on useful methodology rather than statistical properties for their own sake some empirical applications to economic data are described the paper deals separately with nonparametric density estimation nonparametric regression estimation and estimation of semiparametric models

deregulation ownership and productivity growth in the banking industry evidence from india this paper analyzes the relationship between deregulation and total factor productivity tfp growth in the indian banking industry using a generalized shadow cost function approach tfp growth is decomposed into a technological change a scale and a miscellaneous component a disaggregated panel data analysis using the population of public and private banks over 1985 96 that covers both pre and post deregulation periods indicates that a significant decline in regulatory distortions and the anticipated increase in tfp growth have not yet materialized following deregulation while private sector banks have improved their performance mainly due to the freedom to expand output public sector banks have not responded well to the deregulation measures

parametric and semi parametric modelling of vacation expenditures we analyse several limited dependent variable models explaining the budget share that dutch families spend on vacations to take account of the substantial number of zero shares two types of models are used the first is the single equation censored regression model we estimate and test several parametric and semi parametric extensions of the tobit model second we consider two equation models in which the participation decision and the decision on the amount to spend are treated separately the first decision is modelled as a binary choice model the second as a conditional regression we estimate and test parametric and semi parametric specifications

deregulation and productivity decline the case of spanish savings banks abstract during the 1980s many regulatory constraints limiting competition in spanish banking were relaxed or removed although deregulation came later to savings banks than to the rest of the banking sector two consequences of partial deregulation of savings banks have been a rapid growth in branching activity much of it geographically dispersed and a burst of merger activity in this paper we investigate productive efficiency and total factor productivity change in spanish savings banks over the 1986 1991 post deregulation period neither branching nor mergers provide an adequate explanation for the magnitude or the nature of the productivity decline we observe over the period

a note on banking efficiency in portugal new vs old banks following entry into the european community in 1986 portugal transformed rapidly its repressed banking system with deregulation the opening of borders the granting of new banking licenses and privatization in a more competitive banking system one would expect a priori an increase in operational efficiency this paper attempts to quantify the magnitude of efficiency gains over the years 1990 1995 moreover the paper documents the relative efficiency performance of new domestic banks not hampered by a legacy of inefficiency from the past they could operate nearer the efficiency frontier the case of portugal provides unique information on the joint effect of deregulation and the granting of new banking licenses on the change in operational efficiency of a previously repressed banking system

analyzing and forecasting tourism demand with arar algorithm abstract this study investigates the arar model and its usefulness as a forecast generating mechanism for tourism demand for nine major tourist destinations in the asian pacific region the analysis is conducted on monthly inflow of international visitors covering the period 1975 01 2006 12 in monthly series we consider 6 12 18 and 24 months ahead forecasting horizons the accuracy of the forecasts in most cases is robust to the forecasting horizon based on such forecasting performance metric as mean absolute percentage error mape and root mean square error rmse the study is further expanded by including quarterly series in the forecasting exercise to ensure the reliability of the forecasting evaluation the 2 4 6 and 8 quarters ahead forecasting horizons are investigated a comparison between forecasts generated by monthly and quarterly data reveals that the performance is broadly similar finally the forecasts of arar are compared with those of seasonal arima which has been proven reliable in many forecasting contexts indeed arar model can be deemed as credible alternatives when modeling and forecasting tourism demand

a double hurdle analysis of travel expenditure baby boomer seniors versus older seniors abstract this study examined the socio demographic and economic determinants of leisure travel expenditure and compared these determinants in baby boomer senior households and older senior households in the united states unlike previous studies this study performed heckman s double hurdle analysis using the consumer expenditure survey ces to present a two step process for making travel consumption decisions the results revealed that more baby boomer senior households participated in leisure travels than older senior households however among those households that chose to travel the mean expenditure of the older senior group was higher than for baby boomers this study also showed similarities and differences in the determinants of travel consumption decisions between baby boomer seniors and older seniors this two step approach provided in depth information on the processes involved in deciding to travel and how much to spend on travel this additional information will be valuable in understanding senior consumers in the tourism industry

malmquist type indices in the presence of negative data an application to bank branches in this paper we develop an index and an indicator of productivity change that can be used with negative data for that purpose the range directional model rdm a particular case of the directional distance function is used for computing efficiency in the presence of negative data we use rdm efficiency measures to arrive at a malmquist type index which can reflect productivity change and we use rdm inefficiency measures to arrive at a luenberger productivity indicator and relate the two the productivity index and indicator are developed relative to a fixed meta technology and so they are referred to as a meta malmquist index and meta luenberger indicator we also address the fact that vrs technologies are used for computing the productivity index and indicator a requirement under negative data which raises issues relating to the interpretability of the index we illustrate how the meta malmquist index can be used not only for comparing the performance of a unit in two time periods but also for comparing the performance of two different units at the same or different time periods the proposed approach is then applied to a sample of bank branches where negative data were involved the paper shows how the approach yields information from a variety of perspectives on performance which management can use

semiparametric econometrics a survey summary semiparametric econometric models contain both parametric and nonparametric components reflecting in some fashion what has been learned from economic theory and previous empirical experience and what remains unknown they raise such questions as how well the parametric component can be estimated and how to construct rules of inference with good statistical properties the paper attempts to survey the econometric and most relevant statistical literature on semiparametric inference and includes a partial bibliography

the impact of financial liberalization on bank efficiency evidence from latin america and asia this article investigates the impact of financial liberalization on bank efficiency using data for a sample of over 4000 bank year observations from ten emerging economies for the period 1991 2000 we use data envelopment analysis dea to calculate bank efficiency at the individual bank level bank efficiency measures are then aggregated at the country level to investigate the relationship between financial liberalization and bank efficiency using a panel least square fixed effects model overall we find strong support for the positive impact of financial liberalization programmes on bank efficiency

top wealth shares in the uk over more than a century abstract recent research highlighted controversy about the evolution of concentration of personal wealth in this paper we provide new evidence about the long run evolution of top wealth shares for the united kingdom the new series covers a long period from 1895 to the present and has a different point of departure from the previous literature we start with the analysis of the distribution of estates left at death we find that the application to the estate data of mortality multipliers to yield estimates of wealth among the living does not substantially change the degree of concentration over much of the period both in the uk and us allowing inferences to be made for years when this method cannot be applied the results show that wealth concentration in the uk remained relatively constant during the first wave of globalization but then decreased dramatically in the period from 1914 to 1979 the uk went from being more unequal in terms of wealth than the us to being less unequal however the decline in uk wealth concentration came to an end around 1980 and since then there is evidence of an increase in top shares notably in the distribution of wealth excluding housing in recent years we investigate the triangulating evidence provided by data on capital income concentration and on reported super fortunes

china s role in world cotton and textile markets a joint computable general equilibrium partial equilibrium approach under the uruguay round s agreement on textiles and clothing atc the quotas inherited from the multifibre arrangement were gradually phased out between january 1995 and 31 december 2004 this study estimates the impact of the atc s implementation on china s textile industry and china s cotton sector the study finds that assuming equilibrium levels of income and exchange rates the adoption of atc are expected to increase china s net apparel exports textile production cotton consumption cotton production and cotton imports however this study fails to support the hypothesis that the adoption of the atc results in china supplanting the textile industries of the rest of the developing world the impacts on cotton are also smaller than indicated by previous studies these outcomes are somewhat sensitive to estimates of expected efficiency gains around the world

estimating input specific technical inefficiency the case of the tunisian banking industry abstract this paper presents an econometric model to estimate input specific technical efficiency iste in a panel data framework it extends the few existing models to estimate iste it can be applied to any flexible functional form and technical inefficiency is firm specific and time variant this model is applied to obtain estimates of technical inefficiency specific to factors of production in the tunisian banking industry it is shown that technical efficiency of labor and capital inputs are decreasing over time labor input is more inefficiently used than capital input and banks which are relatively more efficient in using capital input are less efficient in using labor input

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