Globalsaon and nernaonal negraon can yeld effcency gans hrough he promoon of compeon and rade n markes for nernaonally raded goods. A he frm level, exposure o compeve pressures has creaed a necessy for frms o operae as close as possble o he echnology froner n order o survve. Furhermore, ncreased negraon has lead o an nflux of nvesmen by Mulnaonal corporaons who brng wh hem echnologcal nnovaons. Ths has he effec of mprovng overall producvy by shfng he bes pracce echnology froner whle a he same me makng ncreasngly dffcul for smaller compeors o survve. In an Irsh conex, he food ndusry has recenly been acknowledged n naonal polcy as an mporan secor for fuure developmen. The am of hs paper s o measure he producvy performance of he food processng ndusry n Ireland and esablsh he exen o whch globalsaon has brough abou effcency and producvy gans o he ndusry. Key Words: Food Indusry, Ireland, Producvy, Sochasc Producon Funcon JEL Codes: D4, L66 1. Inroducon Over he course of he 1990s he Irsh economy grew a an unprecedened rae. Beween 1990 and 003 he numbers n employmen expanded by 55 per cen and oupu grew a an average of 9 per cen per annum. The mos ofen ced explanaon for Ireland s success sory was he change n polcy emphass, dang back o he 1960s, oward an ouward-lookng focus n erms of encouragng expors and nward nvesmen, parcularly n he manufacurng secor. Over he course of he 1990s he ndusral secor n Ireland grew by 7 per cen n erms of employmen, wh 67 per cen of hs accouned for by foregn-owned enerprses, and 49 per cen n erms of ne oupu, 88 per cen of whch was due o foregn-owned enerprses (CSO, 1991; 001). By 001, foregn-owned enerprses consued 87 per cen of ne oupu n he manufacurng secor. A an aggregae level research has shown ha n general foregnowned companes n he Irsh manufacurng secor are more producve 1 and expor nensve han her ndgenous counerpars (Ruane and Ugur, 004). However, n he 1 Based on paral producvy measures. 1

4 face of an ncreasng cos envronmen, poor economc condons n expor markes and gven he secor s ncreasng relance on foregn-owned enerprses, producvy s a key ssue of concern for busness and polcy makers n Ireland as he fuure compeveness of all secors s pushed o he forefron of he polcy agenda. An mporan queson, herefore, for he fuure of manufacurng s o asceran he exen o whch he secor has remaned producve n he face of such pressures. In addon, he mpac of globalsaon n he form of foregn ownershp of frms and an expor orened focus on producvy s also mporan o undersand. Of parcular neres n an Irsh conex s he food processng ndusry. The food drnks and obacco secor n Ireland drecly employed 54,000 people n 004 (.9 per cen of oal employmen) and conrbued 6.4 per cen o GDP (Deparmen of Agrculure and Food, 005). In 003, he value of expors from he food and drnks secor was esmaed a 6.7 bllon (An Bord Ba, 004). Unlke he res of he manufacurng secor n Ireland, food and drnks processng s sll very ndgenous n naure wh foregn companes consung approxmaely 5 per cen of employmen n 001 (compared wh 49 per cen for manufacurng as a whole) (CSO, 001). Indgenous frms n he food and drnks secor, however, accoun for 55 per cen of oal ndgenous expors suggesng ha he secor performs well n erms of compeveness n world markes. The secor has recenly been acknowledged n naonal publc polcy as an mporan secor for he fuure developmen of Irsh ndusry havng been gven a specfc sub-programme n he Operaonal Programme for Indusral Developmen ( ) and subsequenly a seres of naves n he Naonal Developmen Plan Prevous research has found ha he Irsh food ndusry performed well relave o oher EU counres n erms of s compeveness n he md-1990s, bu no n he hgh growh secors (Teagasc, 001). Enhancng he compeveness of he secor has been ced as beng a parcularly mporan facor n ensurng he fuure of he ndusry and Irsh ndgenous ndusry n general. Whls facng he same challenges as he manufacurng secor as a whole n erms of cos pressures, mananng compeveness s even more crucal for he food manufacurng secor; frsly, gven he sgnfcan shfs n consumer preferences over he las decade leadng o a fundamenal change n wha domesc and nernaonal consumers demand; secondly, gven he necessy of frms o adhere o ncreasngly srngen food safey regulaons and he cos pressures hs mposes; and fnally, gven he subsanal reforms of he Common Agrculural Polcy and he general rend oward a more lberal radng envronmen for food producs (An Bord Ba, 004). A key ndcaor of compeveness s producvy and as such he focus of hs paper s on analysng he producvy performance of he food manufacurng secor n Ireland beween 1995 and 003 usng frm level daa provded by Census of Indusral Producon (CSO, ). Ths wll be acheved hrough he paramerc esmaon of sochasc producon funcons of he echnology used by NACE 3-dg sub-secors of frms and he consrucon of ndexes of producvy change for each of hese sub- These measures nclude; capal nvesmen o encourage ncreased effcency; he provson of a research, echnology and nnovaon fund; he provson of a fund o suppor promoonal work by An Bord Ba and o enhance he markeng capables of ndvdual frms; and he provson of a fund o asss n human resource developmen parcularly n he area of ranng (Deparmen of Agrculure and Food, 001).

5 secors. Gven he ndgenous naure of he secor and he mporance of expor markes for many food producon frms, hs sudy wll analyse producvy performance by ownershp and expor saus o asceran who he key drvers of producvy growh n he secor really are. Secon of hs paper oulnes he model and mehods used o acheve hese ams. Secon 3 presens he daa. The emprcal resuls are dealed n secon 4 and he paper concludes wh secon 5.. Mehods The producon echnology n he food processng ndusry s frs defned usng a sochasc producon froner. Producvy changes are hen measured by analysng changes n componens of hs froner over me. In he sochasc producon froner, oupu s expressed as a funcon of npus, echncal neffcences capurng he degree o whch frms produce below he opmal level of producon and a random error componen. y ( x ) + v u = f ; β (1) where y s he oupu of he h frm n me perod, x s he vecor of npus no he producon process of he h frm n me perod, β s he vecor of parameers o be esmaed capurng he relaonshp beween npus and oupus across frms and me, v represens sascal nose and oher random exernal evens nfluencng he producon process 3 and u are he frm specfc neffcency effecs, whch may be me varyng. Coell e al. s (1998) specfcaon of he me-varyng echncal effcency effecs s consdered, ha s u = ( exp ( η( T ))) where η s a parameer o be u u esmaed. 4 If = 0 he frm s effcen and operaes on he producon froner n ha parcular me perod, whle f u > 0, here are neffcences and he frm s operang beneah he froner a me. and are assumed o be ndependen. v u The frs sep n esmang a sochasc producon froner s o specfy an approprae funconal form for he model. In hs paper a Cobb Douglas funconal form s assumed. 5 The Cobb Douglas sochasc producon froner s presened n equaon (). ln y K 0 + βk ln k =1 k = α x + v u () 3 v are assumed o be d N( 0, σ ) v. 4 u are assumed o be d as runcaons of N( µ, σ ) u. 5 A ranslog funconal form s also consdered bu n mos cases s no found o sgnfcanly mprove on he smpler Cobb-Douglas model. Furhermore, due o sample sze and mulcollneary problems he ranslog s no suable o hs parcular applcaon. 3

6 By ncludng a me rend and neracons beween me and he npus, echncal change componens can also be ncorporaed no he funconal form of he model. Ths s llusraed n equaon (3). ln y K K 1 = α 0 + βk ln x k + ω0 + ω00 + ωk ln x k + v u (3) k = 1 k = 1 Maxmum lkelhood esmaon wll produce conssen parameer and neffcency esmaes based on he sochasc producon froner. 6 The model s esmaed usng Saa/S.E. Verson 8.0 (Saa Corporaon, 003). The purpose of consrucng a producvy ndex s o measure oupu growh ha s ne of npu growh, ha s oupu growh due o echncal change, effcency change or he conrbuon of reurns o scale. For a sochasc producon froner, wh a sngle scalar oupu, a Dvsa ndex of he rae of producvy change can be defned as he dfference beween he rae of change of oupu and he rae of change of an npu quany ndex. 7 T FP & y& X& = (4) To fnd he rae of change n oupu, y&, where oupu y s defned by he producon funcon n equaon (1), s necessary o oally dfferenae he log of he producon funcon. Ths yelds hree componens. Frs, he rae of echncal change n frm n perod : ( x ; β ) f TC & ln = (5) Second, he rae of echncal effcency change n frm n perod : u EC & = (6) Thrd, he rae of change n oupu as a resul of a change n an npu quany on frm n perod : ln y X = ε k x& k k (7) where ε k are elasces of oupu wh respec o each of he npus. Subsung equaons (5), (6) and (7) no equaon (4) yelds: 6 The varance parameers σ = σ v + σ u and γ = σ u σ, where γ measures he proporon of oal varance arbued o he neffcency effecs, are also esmaed. 7 Ths approach follows ha of Kumbhakar and Lovell (000) ]. 4

Usng hs defnon equaon (8) can be x& k The frs componen of Equaon (9) measures he rae of echncal change, he second componen measures he rae of echncal effcency change and he fnal componen measures he rae of change n oupu as a resul of a change n he scale of producon. Equaon (10) descrbes how T & C relaes o he componens of he Cobb Douglas producon funcon gven n equaon (3). K y TC & = = ω0 + ω00 + ωk ln xk (10) k= 1 The frs wo componens measure neural echncal change, common o all frms. A posve/negave sgn on ω 0 ndcaes neural echncal progress/regress whle a posve/negave sgn on ω 00 ndcaes ha echncal progress/regress s akng place a an ncreasng/decreasng rae. The hrd componen measures non-neural echncal change. A posve/negave sgn on ω k ndcaes ha here s a posve/negave npu bas assocaed wh npu k, leadng o non-neural echncal progress/regress. The echncal change ndex beween perods and +1 s consruced based on an arhmec average of hs componen each year. TCI = ( TC + T& C ) & (11) Snce EC & = u, he effcency change ndex beween perods and +1 s consruced based on he change n he average effcency levels n each year. Tha s: ECI TE = TE + 1 E = ( exp( u ) v ) E( exp( u ) v ) Fnally, each npu elascy can be evaluaed as: (9) (1) 5

The model s esmaed for sx sub-groups of he wo-dg NACE classfcaon, 15, of frms nvolved n he manufacure of food producs (dealed n Table 1). Ths consues 1,10 frms and 6,51 observaons over he enre sample perod.

As dscussed, n hs model producvy can be mproved va hree mechansms: frsly, hrough mprovemens n he bes pracce echnology froner; secondly, hrough mprovemens n he performance of he average frm relave o he bes pracce froner; and fnally, hrough changes n he npu mx (scale effecs), whn he gven echnologcal consrans. The resuls are presened n Table 6.

In he frs subsecor, he producon, processng and preservng of mea and mea producs (NACE 151), producvy growh occurs a an average rae of close o 1 per cen per annum. Ths growh s drven by echncal progress n frs half of he sample perod and 10

Techncal regress of 5 per cen per annum s evden n frs 4 years of he sample wh some recovery hereafer. Average effcency levels remaned sac over he perod suggesng ha he negave mpac on echnology experenced by he secor affeced all frms equally. In conras, changes n he npu mx over me conrbue posvely o producvy n he frs 5 years of he sample leadng o producvy mprovemens of almos 7 per cen per annum.

Wh lle mprovemen n he echnology froner over me, s unsurprsng ha here s some mprovemen evden n average effcency levels wh growh of jus over 1 per cen per annum recorded. The secor nvolved n he manufacure of dary producs (NACE 155), performs well hroughou he perod. Techncal progress of 4 per cen per annum s evden n he frs half selng o a more moderae growh rae of 1 per cen per annum for laer me perods.

By separang he resuls for each 3-dg sub-secor by ownershp (foregn vs. domesc) and expor saus (exporng vs. non-exporng) a pcure of he effec of globalsaon on producvy n he secor can be esablshed. Table 7 presens he resuls. I s clear from he above able ha rade and orgn of ownershp mpac on sub-secors n dfferen ways. In general, as mgh be expeced, exporng frms perform beer han non-exporng frms wh he excepon of he manufacure of oher food producs (NACE 158) where exporng frms experence a slghly slower pace of growh han non-exporng. Overall, foregn-owned frms make up a very small proporon of frms n he secor. Neverheless, n some sub-secors hey experence a far superor producvy performance over he sample perod. A more dealed analyss of each of he sub-secors s presened below. For he producon, processng and preservng of mea and mea producs (NACE 151), exporers ouperform non-exporng frms due o a faser pace of echncal progress, parcularly n frs half of he sample perod. Whle hey are also more effcen n ha on average hey are closer o he bes pracce froner, non-exporng frms experence a faser pace of growh n overall effcency levels over he sample perod. I s dffcul o asceran he mpac of foregn ownershp on producvy performance n hs secor as s prmarly an ndgenous secor. The small number of foregn-owned frms ha are presen perform poorly relave o domesc producers. For he processng and preservng of fsh and fsh producs (NACE 15) he exen of globalsaon s hghly correlaed wh producvy mprovemens.

Decomposon by ownershp reveals ha foregn frms perform beer n relaon o echncal change whle ndgenous frms perform beer n relaon o effcency mprovemens. For he manufacure of dary producs (NACE 155), frms servng he domesc marke only are more effcen and more echnologcally progressve, however, exporng frms are beer able o adap her npu mx o benef from reurns o scale. Overall hs leads o a superor performance by exporng frms n hs secor. Foregn-owned frms perform much beer han domesc frms. They are more effcen han domesc-owned counerpars who experence a declne n average effcency levels over he sample perod. They also experence a much faser pace of echncal progress. The fas pace of producvy growh experenced n he secor producng gran mll producs, sarch, sarch producs and anmal feed (NACE 156/7) s prmarly due o exporng frms who perform beer n erms of faser raes of echncal progress and hgher average effcency levels. Indgenous frms perform beer n hs secor bu here are very few foregn-owned enerprses makng dffcul for any conclusons o be drawn. 13

16 Fnally, n relaon o he producon of oher foods (NACE 158), exporers have hgher average effcency levels whch mprove sgnfcanly over me bu, n conras o wha mgh be expeced, non-exporers experence a faser pace of echncal progress leadng o a beer overall producvy performance. Foregn-owned frms have a hgher average level of effcency and perform beer over me on hs measure however ndgenous frms are he forerunners n echnologcal progress experencng a faser rae of echncal change and faser raes producvy growh overall. Gven he ndgenous naure of he Irsh food secor and s success on world markes over he course of he 1990s, mgh be expeced ha domesc frms ou-perform her foregn-owned counerpars. However, hs s only he case n hree ou of he sx subsecors analysed. Despe hs fac, n mos cases, Irsh owned-frms are he fore-runners n echnologcal advancemens n he secor wh foregn-owned frms n general performng beer on effcency measures. Ths s parcularly evden on he scale effcency measure. 19 Ths mgh sugges he presence of a group of neffcen Irshowned companes unable o keep up wh he pace of echncal progress n he secor hus draggng down he average effcency performance of he domesc-owned group. Ths laer fndng could be explaned by he fac ha he Irsh food ndusry has ended o under-nves n ranng poenally leadng o lower average effcency levels and unyelded poenal for greaer economes of scale n domesc frms. 0 In conras, as expeced, he evdence suggess ha for he mos par exporng frms are boh more echnologcally progressve and effcen han hose servng he domesc marke only.

Frsly, o wha exen has he secor has remaned producve n he face of new consrans facng he secor n Ireland n he lae 1990s and early 000s, namely, rsng cos pressures, srucural changes n consumers ases and preferences and ncreased exposure o exernal pressures due o an ncreasngly more lberal rade envronmen. Secondly, hs paper examnes he mpac of globalsaon on producvy by comparng he performance of ndgenous frms wh her foregn-owned counerpars and exporng frms wh hose who solely rely on he domesc marke. In relaon o he frs ssue, an mporan fndng revealed by he resuls presened n hs paper s ha he pace of producvy growh slows, and n some cases producvy self even declnes, beween 1999 and 003 when compared wh producvy growh raes experenced beween 1995 and Ths s a worryng rend parcularly gven he mporance of hs secor o ndgenous ndusry n Ireland.
