does microfinance change informal lending in village economies evidence from bangladesh this paper examines how availability of microfinance influences households borrowing from informal sources in village economies it uses a unique household level panel data set which spans more than two decades 1987 2008 from rural bangladesh we find that households access to microfinance reduces the incidence of borrowing from informal sources but not the amount of borrowing we find that less poor households benefit more in terms of reducing their reliance on informal borrowing and that the benefit accrues over time we also find that having access to microfinance increases women s informal borrowing for small consumption usage without facilitating access to new business opportunities

assessing interactions among education social insurance and labor market policies in morocco this paper develops a general equilibrium model to assess the impact that integrated reforms of macroeconomic education and social protection policies can have on employment the model presents three innovations first it formalizes the production of skills in the economy by following sex age cohorts through the various levels of the education and training systems given dropout and repetition rates second it incorporates a module that projects social insurance expenditures as a function of the demographic structure of the country and the rules of the pension system finally it develops a very detailed description of the labor market where informality reflects strategic decisions by workers and not necessarily exclusion the model is applied to morocco the results of various simulations illustrate the importance of coordinating macro education and social protection policies in order to achieve meaningful effects on employment levels in particular the author show that isolated interventions to improve the internal efficiency of the education system can aggravate the unemployment problem that subsidies to investments are more efficient in sectors intensive in skilled labor and that not controlling the growth of pension expenditures and the tax wedge can depress employment in the formal sector

from ngos to banks does institutional transformation alter the business model of microfinance institutions microfinance which pledges to provide financial services to people without access to banking is chiefly run by non governmental organizations ngos little is known about the extent to which the transformation of these ngos into shareholder owned and most often regulated firms affects the way microfinance institutions mfis conduct their business by applying the event study methodology to 66 mfis that have transformed we quantify the effect that transformation has on the mfis business models our results suggest that portfolio yield is driven down by 3 9 percentage points due to transformation indicating that clients get more favorable interest rates at the same time mfis are able to significantly cut down their operational expenses of which 1 1 percentage points can be attributed to transformation other findings include a steep increase in commercial debt leverage and deposits a significant decrease in the fluctuation of funding costs and a sharp rise in average loan size profitability goes down in the short and medium term while return on equity is driven up in the medium to long run by exploiting within mfi data our approach goes beyond previous studies that mainly relied on between mfi data overall the results suggest that transformed mfis become an attractive environment for investors potentially encouraging a more profit seeking behavior among transformed mfis

where does microfinance flourish microfinance institution performance in macroeconomic context abstract we study whether and how the success of microfinance institutions mfi s depends on the country level context in particular macroeconomic and macro institutional features understanding these linkages can make mfi evaluation more accurate and further can help to locate microfinance in the broader picture of economic development we collect data on 373 mfis and merge it with country level economic and institutional data evidence arises for complementarity between mfi performance and the broader economy for example mfis are more likely to cover costs when growth is stronger and mfis in financially deeper economies have lower default and operating costs and charge lower interest rates there is also evidence suggestive of substitutability or rivalry for example more manufacturing and higher workforce participation are associated with slower growth in mfi outreach overall the country context appears to be an important determinant of mfi performance mfi performance should be handicapped for the environment in which it was achieved

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

markups aggregation and inventory adjustment in this paper i suggest a unified explanation for two puzzles in the inventory literature first estimates of inventory speeds of adjustment in aggregate data are very small relative to the apparent rapid reaction of stocks to unanticipated variations in sales second estimates of inventory speeds of adjustment in firm level data are significantly higher than in aggregate data the paper develops a multisector model where inventories are held to avoid stockouts and price markups vary along the business cycle the omission of countercyclical markup variations from inventory targets introduces a downward bias in estimates of adjustment speeds obtained from partial adjustment models when the cyclicality of markups differs across sectors this downward bias is shown to be more severe with aggregate rather than firm level data similar results apply not only to inventories but also to labor and prices montercarlo simulations of a calibrated version of the model suggest that these biases are quantitatively significant

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

the dominance of inefficiencies over scale and product mix economies in banking abstract this study measures and analyzes inefficiencies for all u s banks in 1984 inefficiencies are measured relative to a thick frontier cost function and are found to dominate measured scale and product mix economies most inefficiencies are operational in nature involving the overuse of physical inputs rather than financial involving overpayment of interest also technical inefficiencies proportionate overuse of all inputs dominate allocative inefficiencies improper mix of inputs these results suggest that competitive pressures in banking from deregulation will be focused primarily on banks that do not control costs rather than on those of a particular size or product mix

economies of scope of lending and mobilizing deposits in microfinance institutions a semiparametric analysis microfinance emerged as an innovation in lending to the rural poor in asia and in response to frequent failure of previous interventions in rural financial markets such as directed and subsidized production credit disbursed by agricultural development banks while it started as a collection of banking practices built around providing small loans typically without collateral and accepting tiny savings deposits armendariz de aghion and morduch 2005 p 1 today many microfinance institutions mfis expand their services and strive to offer payment and savings facilities insurance housing and longer term loans to marginalized clientele in rural and urban settings estimates show that there are at least 10 000 microfinance programs worldwide two related and important trends are now emerging the first is toward commercialization which essentially is transforming ngo mfis into regulated intermediaries with the intent to lower costs by accessing deposits as well as strengthen the organizations by privatization the second trend is a renewed interest in experimentation to mobilize savings with emphasis on rural savings economies of scope imply that expansion into the savings market can be more cost efficient if done by the same mfis which makes it a significant factor in assessing the feasibility of these innovations however there are few studies that estimate the magnitude and sign of scope economies in this paper we present some preliminary evidence on scope economies using a large sample of mfis

do regulated microfinance institutions achieve better sustainability and outreach cross country evidence in spite of increasing pressure on microfinance institutions mfis operating in developing countries to transform into regulated financial intermediaries to date no study has investigated whether regulated mfis actually achieve better financial results and reach more poor clients than nonregulated mfis this article explores the impact of regulation on mfi performance using newly released data for 114 mfis from 62 countries in an empirical model where performance is specified as a function of mfi specific regulatory macroeconomic and institutional variables consistent with recent cross country evidence on the impact of banking regulations on bank performance barth et al 2004 this article finds that regulatory involvement does not directly affect performance either in terms of operational self sustainability or outreach the article also finds that less leveraged mfis have better sustainability the policy implication is that mfis transformation into regulated financial institutions is may not

unionism mio the cyclical behavior of the labor tv rket in u s manufacturing t he traditional view of market dynamics implies that when demand varies intertemporal variation in quantities exchanged increases as prices become less flexible this reasoning leads to the proposition that wage and price rigidities are important contributors to cyclical fluctuations in output fischer 1977a and gray 1978 based formal macro models on this principle although this view is common it has little empirical support the coexistence of union and nonunion establishments engaged in similar activities contains potential for testing its merits economists have long maintained that in the short run union wages are less flexible than nonunion wages dunlop 1950 rees 1951 this difference should produce larger fluctuations in union employment and hours empirical studies have generally supported the union wage rigidity hypothesis lewis 1963 ashenfelter johnson and pencavel 1972 and hendricks 1981 2 but until recently lack of data precluded analysis of hours and employment definitive answers to the important questions concerning unions influence on cyclical behavior require yet unavailable information matching the behavior of firms and characteristics of workers but data from modem surveys have allowed considerable progress nevertheless it remains a challenge to determine how much of differences observed in the stability of labor utilization are attributable to differences in the stability of demand medoff 1979 and raisian 1979 report that cyclical variation of employment and hours is indeed greater for union labor but despite attempts to allay suspicion that their finding arises primarily from concentration of union members in cyclically sensitive industries both studies leave room for doubt raisian estimated functions relating an individual s wage and weeks worked in a year to a proxy for excess demand that year s unemployment rate in the worker s industry the technique is attractive but raisian s data included workers from the entire economy and the industries were broad aggregates thus differences in the union and nonunion groups compositions may play a large role medoff who confined his study to production workers in manufacturing and used data allowing finer partitions investigated the importance of composition more thoroughly but he did not estimate relationships between adjustments in employment or hours and a measure of demand furthermore his focus was principally on the composition of manhours adjustments rather than their size in this paper i combine the strongest features of the medoff and raisian studies in further examination of the influence of unionism on cyclical fluctuations using current population surveys u s department of commerce 1978 from may of 1973 75 my analysis covers production workers in manufacturing during a period of rising inflation and unemployment the heart of the analysis is a measure of residual employment that quantifies by three digit industry and year shortrun excess demand for labor i construct this variable from employment time series and use it to estimate union nonunion differences in the cyclical responses of unemployment hourly wage rates and hours worked the results are consistent with the view that increasing rigidity in wages amplifies cyclical fluctuations in the utilization of labor the wage regressions add further to the literature s already strong support for the union wage rigidity hypothesis the employment status and hours regressions imply that the sensitivities of employment received for publication august 12 1981 revision accepted for publication february 11 1983 federal reserve bank of dallas this paper is based on my ph d dissertation which was completed at ucla with financial assistance from the rand corporation and the department of labor comments by referees and by participants of labor workshops at ucla and the university of chicago as well as the computation assistance of brian mckee are gratefully acknowledged i am responsible for any remaining errors the views expressed should not be attributed to the federal reserve bank of dallas or the federal reserve system one study is gordon 1982 who concludes page 41 that macroeconomic instability in the united states has been aggravated by the unusually sluggish behavior of nominal wages in the postwar era 2see also johnson 1975 parsley 1980 and moore and raisian 1980

determination of employment with wage and price speculation the purpose of this paper is to investigate whether aggregate fluctuations in employment may be explained within a market clearing framework as intertemporal substitution in labor supply and demand an intertemporal substitution model for the firm is derived this model is estimated with a lucas rapping type supply equation empirical results with finnish data lend support to the intertemporal substitution model particularly concerning the demand function specification on the other hand the results for the supply equation are somewhat mixed being rather sensitive to the dynamic specification

buffer stocks and labor demand further evidence this paper presents estimates of a multivariate flexible accelerator model of labor demand hours and the number of production workers which shows that stocks of finished goods unfilled orders and materials inventories have significant impacts upon labor demand univariate time series models are used to capture expectations of the determinants of desired stocks new orders real wages and real raw materials prices and these magnitudes are found to follow a random walk without drift expected new orders and errors in forecasting new orders are found to have an important impact upon labor inputs real wage forecasting errors are found to be important for hours demand

the commercialization of the microfinance industry is there a personal mission drift among credit officers recent research suggests that many microfinance institutions increasingly focus on financial performance at the expense of the social component of their dual objectives existing studies typically assume that capital providers and managers mainly drive this so called mission drift in this study we investigate whether personal mission drift at the credit officer level can further explain the reduced emphasis on poorer clients among microfinance institutions we present both qualitative and quantitative evidence that more experienced credit officers tend to serve fewer vulnerable clients specifically we show that all else being equal credit officer experience is negatively correlated with the provision of small loans loans to young clients and loans to clients with disabilities our qualitative analysis suggests that perceived client risk and preferences for increased time efficiency mainly drive more experienced credit officers relative neglect of more vulnerable clients this drift appears to be reinforced by the industry s incentive schemes therefore credit officer incentives and training should be designed to prevent this mission drift which is observed at the microfinance institution level but is actually initiated at the credit officer level

microfinance mission drift summary claims have been made that microfinance institutions mfis experience mission drift as they increasingly cater to customers who are better off than their original customers we investigate mission drift using average loan size as a main proxy and the mfis lending methodology main market and gender bias as further mission drift measures we employ a large data set of rated multi country mfis spanning 11 years and perform panel data estimations with instruments we find that the average loan size has not increased in the industry as a whole nor is there a tendency toward more individual loans or a higher proportion of lending to urban costumers regressions show that an increase in average profit and average cost tends to increase average loan and the other drift measures more focus should be given to cost efficiency in the mfi

financial performance and outreach a global analysis of leading microbanks microfinance contracts have proven able to secure high rates of loan repayment in the face of limited liability and information asymmetries but high repayment rates have not translated easily into profits for most microbanks profitability though is at the heart of the promise that microfinance can deliver poverty reduction while not relying on ongoing subsidy the authors examine why this promise remains unmet for most institutions using a data set with unusually high quality financial information on 124 institutions in 49 countries they explore the patterns of profitability loan repayment and cost reduction the authors find that institutional design and orientation matter substantially lenders that do not use group based methods to overcome incentive problems experience weaker portfolio quality and lower profit rates when interest rates are raised substantially for these individual based lenders one key to achieving profitability is investing more heavily in staff costs a finding consistent with the economics of information but contrary to the conventional wisdom that profitability is largely a function of minimizing cost

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

determinants of the performance of microfinance institutions a systematic review microfinance institutions mfis generally aim at improving the access of the poor to financial services while at the same time being financially sustainable but what do we know about how mfis reach and combine these two goals we carry out a systematic review of close to 170 papers discussing the determinants of the financial and social performance of mfis the review shows that the most important determinants addressed in the literature are mfi characteristics size age and type of organization their funding sources the quality of organizational governance and the mfis external context such as macro economic institutional and political conditions the evidence on these issues is rather mixed moreover the direction of the relationship between these drivers and mfi performance depends on the context particularly the country specific context finally there is a lack of consensus in the literature on the measurement of financial and social performance due to the complexity of the concept we argue that social performance should only be assessed by using a multidimensional perspective this can be done either by applying recent and holistic social performance measures such as the spi4 or at least by using a combination of proxies such as outreach gender and rural measures

the impact of mobile financial services usage on microfinance delinquency abstractthis paper studies the impact of mobile financial systems usage on microcredit delinquency ratios in tunisia by using either a two part model or matching econometric procedures our large dataset contains all of the administrative registers that belong to the six branches of enda the incumbent institution leader in tunisia we find a significant reduction of 4 92 days of late repayment for an average user of mfs in an environment where 15 of loans have been paid late at least once we foresee a tremendous opportunity to improve the mfis repayment ratios and consequently provide microcredit customers with more financing for income generating activities

excess labour and the business cycle a comparative study of japan germany the united kingdom and the united states against the background of firm specific human capital theory this paper investigates empirically the relative propensity of manufacturing industries in japan germany the united kingdom and the united states to hold excess labour over the business cycle both stock and utilization dimensions of the labour input are integrated into the study throughout discussion is linked to earlier research that has analysed the relative international performance of the japanese labour market

efficiency and technical progress in banking empirical results for a panel of german cooperative banks abstract using 1989 1992 individual data of 757 german cooperative banks and applying the intermediation approach we specify a multi product translog cost function for this part of the german banking industry for all size classes moderate economies of scale can be identified there is also evidence of economies of scope which supports the notion of universal banking as for cost efficiency we find that the average banks in all size classes deviate considerably from the best practice cost frontier all banks enjoy growth of total factor productivity which is higher for the smaller banks in the sample

do microfinance institutions benefit from integrating financial and nonfinancial services this article examines the impact of microfinance plus i e coordinated combination of financial and nonfinancial services on the performance of microfinance institutions mfis using a global data set of mfis in 77 countries we find that the provision of nonfinancial services does not harm nor improve mfis financial sustainability and efficiency the results however suggest that the provision of social services is associated with improved loan quality and greater depth of outreach

inventories layoffs and the short run demand for labor this paper presents a theoretical and empirical analysis of the short run employment layoff and inventory strategies of firms on average more than two thirds of all layoffs in american manufacturing end in a rehire by the employer of origin martin feldstein 1975 david lilien 1980 these temporary layoffs have recently accounted for about half of all ongoing employer initiated spells of unemployment in that sector see table 1 and have led to a revised interpretation both of the involuntary nature of these separations costas azariadis 1975 feldstein 1976 martin baily 1977 and of the durability of employment relationships evidently a significant proportion of unemployed workers know that the conditions that generated their separations are temporary and so they expect to be recalled within some reasonable time the point of departure for this paper is in interpreting these findings as evidence of a privately and socially efficient stock of excess capacity held against contingent future demands that is as an inventory of a productive input this view leads to empirically refutable hypotheses regarding both the role of temporary layoffs and the circumstances under which they will be important in particular both excess capacity idle resources and inventories are devices by which firms may economize on the costs of rapid adjustments when faced with unstable market conditions george stigler 1939 in such an environment the demands for layoffs and for other buffer stocks are jointly determined elements of long run technology the choice among alternative stocks will depend on relative profitabilities and firms may choose to hold stocks of inputs as a substitute for inventory accumulation especially if the costs of varying capacity or of storage are important this reasoning implies that i the structure of short run employment and layoff decisions will vary across firms and industries and ii differences in these structures will be systematically related to the role of inventories in firms dynamic strategies some perspective is warranted at least since charles holt et al 1960 economists have recognized the production smoothing role of inventories and the necessity of predicting future demand in making current decisions david belsley 1969 gerald childs 1967 michael ward 1978 similarly one of the contributions of recent work on implicit labor contracts is in viewing the exchange of labor services as a bilateral and durable commitment both these lines of analysis are concerned with the methods firms use to respond to fluctuating demand yet the underlying interrelated nature of employment and inventory decisions has rarely been recognized roger miller 1968 m ishaq nadiri and sherwin rosen 1973 r g crawford 1979 robert hall 1972 this paper aims to provide a framework for evaluating these decisions and in so doing to explain some interesting features of observed labor markets the notion of substitution between inventories of human and physical capital suggests a more disaggregated look at the data table 2 shows the importance of temporary layoffs in the distribution of unemployment among manufacturing industries it reports layoff and total unemployment rates for twelve representative industries over the period 197376 and average layoff rates and recall frequencies for 1958 76 among all 21 twodigit manufacturing industries the correlation between layoff and rehire rates is 6 and the table illustrates this evidently industries with larger than normal layoff rates also tend to have larger rehire frequencies from firm initiated spells of unemployment this university of chicago i am indebted to gary becker robert cotterman sherwin rosen jose scheinkman michael ward finis welch the managing editor and an anonymous referee for discussions and comments at various stages the usual disclaimer applies

are women better bankers to the poor evidence from rural microfinance institutions microfinance institutions mfis provide financial services to the poor and in many ways resemble both banks and non profit organizations many mfis target women because more women than men are poor especially in rural areas studies show that women manage money differently from men and have different leadership styles thus in credit unions and financial firms female and male managers achieve different results in microfinance gender diversity on the board of mfis is beneficial and loans authorized by female loan officers have lower default rates motivated by these findings we ask whether mfis with a female chief executive officer ceo are more efficient at serving the poor without jeopardizing financial sustainability we adapt the banking approach to managerial in efficiency to account for the outreach and sustainability goals of the mfis and evaluate whether mfis outreach efficiency differs by the gender of their respective ceos we estimate a stochastic frontier cost function using the battese coelli 1995 model and the true random effects estimators using panel data from over 250 mfis we find that mfis with female ceos have significantly higher outreach efficiency than mfis with male ceos similar results are found with a two step stochastic frontier approach overall the results suggest that promoting gender diversity at the top levels of mfi management is likely to have both social and financial benefits

which microfinance institutions are becoming more cost effective with time evidence from a mixture model italian speakers tend to stress the second component of german morphologically complex words such as compounds and prefix verbs even if the first component is lexically stressed to improve their prosodic phrasing an automatic pronunciation teaching method was developed based on auditory feedback of prosodically corrected utterances in the learners own voices basically the method copies contours of f0 local speech rate and intensity from reference utterances of a german native speaker to the learners speech signals it also adds emphasis to the stress position in order to help the learners better recognise the correct pronunciation and identify their errors a perception test with german native speakers revealed that manipulated utterances significantly better reflect lexical stress than the corresponding original utterances thus two groups of italian learners of german were provided with different feedback during a training session one group with manipulated utterances in their individual voices and the other with correctly pronounced original utterances in the teacher s voice afterwards both groups produced the same sentences again and german native speakers judged the resulting utterances resynthesised stimuli especially with emphasised stress were found to be a more effective feedback than natural stimuli to learn the correct stress position since resynthesis was obtained without previous segmentation of the learners speech signals this technology could be effectively included in computer assisted language learning software

equilibrium adjustment with endogenous information and inventories the paper analyzes the interaction of information acquisition and inventory flexibility with industry adjustment to imperfectly perceived cost and demand disturbances improved information about disturbances reduces the extent to which disturbances are unperceived and dampens the use of inventories reduced inventory flexibility induces firms to devote more resources to acquiring information about disturbances the analysis demonstrates how equilibrium price and output adjustment depend endogenously on the degree of inventory flexibility and other structural parameters influencing the acquisition of information in this paper we analyze how endogenous information acquisition and inventory flexibility influence price and output adjustment in a competitive industry we focus on the potential substitutability of information acquisition for inventory flexibility when disturbances are imperfectly perceived by individual firms the analysis highlights the general issue of how market adjustment depends on structural parameters that influence agents incentives to acquire information there are several reasons why information acquisition may play a role in market adjustment first the rapid development of information technology has enabled firms to gather and process data relevant to production and sales decisions from a greater number of external and internal sources this trend has reduced the costs of forecasting and monitoring factors influencing production and demand conditions for the individual firm relative to those of its competitors as well as for the industry as a whole in particular it has permitted quicker awareness of changing customer demand as well as greater control of the flow of inputs and intermediate goods during the production process this implies that the resources devoted to information acquisition and processing have come to play an important role in firm decisions 2 second improved information about demand and cost conditions may affect the function of inventories inventory adjustment allows a firm s production costs to be smoothed in response to anticipated movements in demand and costs and to be buffered against unanticipated disturbances see ashley and orr 1985 thus

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

on recalls layoffs variable hours and labor adjustment costs abstract the paper analyzes the employment policy of a firm that can vary both hours and the level of employment the analysis differs from previous work in the adjustment cost literature in that the firm is able to change its employment not only through hires layoffs and quits but also by recalls of employees who were previously laid off thus we introduce the possibility of the firm inventorying the labor input it is shown that this labor inventory potential is necessary if the firm is to ever lay off workers further it is demonstrated that linear rather than strictly convex adjustment costs are then required if the firm is to always recall employees who were previously laid off prior to hiring new workers
