the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

are group affiliated firms really more profitable than nonaffiliated the role of corporate center in influencing the economic performance of business units has been a central research topic in the industrial organization and strategic management literature a common finding is the limited corporate and business group effects recently an emerging line of studies argues that the market inefficiencies and institutional voids in emerging markets can be overcome more efficiently by large diversified business groups than by non group small firms some empirical evidence also shows that non group small firms are significantly less profitable than group affiliated firms this paper raises this issue by empirically investigating the influence of group affiliation on the return on assets and tobin s q of 340 group affiliated firms versus 423 non group firms in taiwan during the period of 1997 1999 the statistical results show that group affiliation can not always create value for member firms the size of the business group matters when affiliated with the largest business groups member firms indeed show improved stock market performance but when firms are affiliated with small and medium sized groups their accounting performance suffers findings of this paper suggest a threshold effect and a u shape relationship between group affiliation and profitability in emerging economies

farm size land yields and the agricultural production function an analysis for fifteen developing countries abstract the paper analyzes the relationship between factor inputs land yields and labor productivity for farms of different size on the basis of fao farm management data for 15 developing countries for all but three countries a strong negative correlation is found between farm size on the one side and factor inputs and yields per hectare on the other the fitting of unconstrained production functions to the above data suggests that in only few cases the decline in yields for increasing farm size can be attributed to decreasing returns to scale the higher yields observed in small farms are mainly to be ascribed to higher factor inputs and to a more intensive use of land therefore where conspicuous labor surpluses exist the superiority of small farming provides solid arguments in favor of land redistribution such an agrarian reform would determine higher output higher labor absorption and a more equitable income distribution thus contributing in a decisive manner to the alleviation of rural poverty the paper also provides estimates of cross sectional production functions for the 15 countries analyzed empirical relations are found between the output elasticities of land labor and intermediate inputs and physical indicators of their scarcity the paper concludes by proposing a simple method for deriving a long term production function for agriculture

farm size and the determinants of productive efficiency in the brazilian center west this paper explores the determinants of technical efficiency and the relationship between farm size and efficiency in the center west of brazil this is the region where agricultural production and total factor productivity have grown the fastest since 1970 it is also a region characterised by unusually large farms technical efficiency is studied with data envelopment analysis and county level data disaggregated by farm size and type of land tenure the efficiency measure is regressed on a set of explanatory variables which includes farm size type of land tenure composition of output access to institutions and indicators of technology and input usage the relationship between farm size and efficiency is found to be non linear with efficiency first falling and then rising with size type of land tenure access to institutions and markets and modern inputs are found to be important determinants of the differences in efficiency across farms

the firm size farm size and transaction costs the case of hazelnut farms in turkey this study analyzes the effects of transaction costs on the size of hazelnut farms in turkey the study finds that higher land slope and higher variance of rain as transaction cost increasing natural effects lead to smaller hazelnut land holdings high slope and weather variation can increase the costs of monitoring the laborers make moving inputs or output up and down harder limit the use of machinery and reduce contractual performance of labor contracts for farm production functions land is a complex input with measurable interactions with nature contrary to common production theory approaches that take natural properties of land as given the study develops a production function that incorporates natural properties such as slope and rain variance the study utilizes two separate data sets for the estimations the first data set explores the characteristics of hazelnut farmers while the second one analyzes the regional characteristics of hazelnut farms

firm size effects on transaction costs associated with effects of scale scope experience and learning there are effects of firm size on transaction costs in the stages of contact contract and control these effects are due to threshold costs in setting up contacts contracts and governance schemes and to differences with respect to the factors that cause transaction costs bounded rationality opportunism uncertainty and transaction specificity of assets implications are considered for firm strategy and public policy

does lack of access to formal credit constrain agricultural production evidence from the land tenancy market in rural india while it is commonly believed that lack of access to government subsidized formal credit underlies observed differences in farm productivity in rural india there is little empirical evidence on this issue in this paper i address this issue by examining whether households use the farm land rental market to equilibrate their access to formal credit as they are known to do in the case of other imperfectly marketable inputs this research reveals however that the advantage formal borrowers enjoy in the tenancy market does not reflect their access to formal credit per se but their greater ownership of inputs such as irrigated land

the political economy of farm size in india the elusive quest the political economy of farm size recognizes both economic and political reasons for an agrarian policy that attempts to influence the size of holdings that any single entrepreneur or family may control after nearly 30 years of discussion and debate and an extensive empirical literature on the subject the interest is still high and definitive answers are still elusive an impressive array of economists have studied this issue in the context of indian agriculture and it is to this literature that we will devote our attention to attempt a synthesis and clarification of the farm size productivity issue even for a single country is daunting yet informed policy requires a sound basis for conscious social choices that would restrict an individual s presumed right to acquire yet more land

choice of contracts in turkish agriculture sharecropping and fixed rent tenancy have coexisted under extremely diverse settings for centuries from labor abundant south and east asia to land abundant west africa and the americas this fact has intrigued generations of economists since adam smith marshall s lucid exposition of the productive inefficiencies of sharecropping in the principles paved the way for a major effort to reconcile neoclassical theory with the reality of coexistence 1 another substantial segment of the literature condemned sharecropping as an exploitative mechanism in semifeudal societies and predicted its downfall 2 more recent theoretical treatments however hail the share contract as a simple yet ingenious arrangement that guarantees the second best outcome in environments characterized by risk input market imperfections and moral hazard 3 the intuition underlying this argument is widely accepted but has yet to yield a general explanation of the real world coexistence phenomenon nor should we expect such an explanation each country and historical episode has its unique climatic technological and institutional characteristics and different motives for the adoption of share contracts may dominate in different settings 4 it is troublesome in fact that our empirical knowledge is so thin given that our theory of agricultural contracts is so rich 5 one reason of course is that appropriate data are costly and difficult to collectfor contractual choice is stubbornly complex and is best observed at the individual agent or household level there has been empirical work but much of it has examined the well worn marshallian theme is sharecropping less efficient than self cultivation 6 our knowledge of the conditions under which different contracts are likely to arise is limited to a handful of studies on the indian subcontinent or the united states in this article i examine the determinants of contractual choice during the 1970s for samples of individual turkish landlords and tenants the data were drawn from a 1973 survey that was national in

the new wave of regional innovation networks analysis characteristics and strategy today the number one priority for competitive advantage is innovation a new approach to regional business development has been pioneered in europe and the u s a this involves building a regional innovation infrastructure learning through networking has proven to be a successful approach in some of europe s more dynamic regional economics such as baden wurttemberg and emilia romagna this involves maximising the complete range of regional innovation assets the state of pennsylvania and other older industry centres are showing that such an approach is transferable from europe to the u s a the paper assesses knowledge transfer at the regional level and outlines the key elements for successful regional innovation networking practices the major finding s are that business networking is an effective way of increasing company turnover that not for profit organizations are excellent for setting up networks because they are trusted and that innovation networks are perhaps the most difficult thought requiring but important of the types of business network conceivable

agency costs and the agricultural firm in the last decade there has been a major rekindling of interest among economists in the form of institutions used to organize resources for production and distribution jensen 1983 distinguishes two agency literatures that share the comparative institutions perspective introduced by coase 1937 1960 principal agency theory e g stiglitz 1975 harris and raviv 1978 shavell 1979 h61mstrom 1979 lewis 1980 provides a mathematical formulation of contractual choice and has been primarily directed to the trade off between risksharing and incentives against labor shirking positive agency theory pioneered by coase 1937 resurrected by alchian and demsetz 1972 and currently represented for example by fama and jensen 1983a is nonmathematical and places relatively more emphasis on explaining actual patterns that characterize industrial organization in agriculture the theory of organizational form has centered largely around tenure choice the theory of tenure choice has an illustrious history in the economics literature e g smith 1922 marshall 1920 heady 1955 day 1967 cheung 1969 rao 1971 stiglitz 1974 reid 1976 newbery and stiglitz 1979 binswanger and rosenzweig 1984 in recent years alternative tenancy arrangements are commonly viewed as types of employment contracts e g newbery and stiglitz 1979 braverman and stiglitz 1975 harris and raviv 1978 shavell 1979 hw1mstrom 1979 lewis 1980 in an innovative departure from the view of tenancy as an employment contract eswaran and kotwal 1985 have modelled share tenancy as a partnership between a landowner who specializes in decision making and a tenant who specializes in labor supervision more generally questions of tenure choice employment contracts manag ment systems and farm size can all be usefully viewed as aspects of agricultural organization the purpose of the present paper i to elucidate this view and to investigate tenure choice as a part of the general study of the nature and causes of the agricultural firm the paper is organized to highlight the inductive approach employed section 2 classiies agricultural firms according to the degree of specialization and who gets the residual payment the classification is combined with previously documented patterns of tenure choice in order to posit a preliminary hypothesi about the relationship between the econo ic environment and the nature of the agricultural firm section 3 uses a principalagency framework to construct a theory of the hypothesized relationship between the degree of separation between labor and management nd l nd quality section 4 provides an illustrative statistical verification of the hypothesis based on a sample of philippine sugarcane f rms section 5 summarizes the paper and discusses two implications of the transaction cost approach for institutional design

social and symbolic capital and responsible entrepreneurship an empirical investigation of sme narratives this paper investigates links between social capital and symbolic capital and responsible entrepreneurship in the context of small and medium enterprises smes the source of the primary data was 144 business profiles written by the owner managers of small businesses in application for a small business awards competition in 2005 included in each of these narratives were claims relating to the firms contributions to wider society relationships with customers employees and stakeholders these narratives were coded and classified in a framework drawn from nahapiet and ghoshal s 1998 academy of management review 23 2 242 266 categorisation of social capital the analysis revealed a range of strategic orientations towards the development of social and symbolic capital along a conceptual continuum ranging from being responsible for oneself to being responsible for others overall the evidence demonstrates the significance of the power inherent in the social relations of smes as a force for ethical behaviour and suggests that normative theories of the development of social capital may provide competitive advantage through responsible behaviour for small business in the global economy

the nature of the agricultural firm abstract models explaining the choice between rent wage and share contracts in agriculture abstract from the large variations within the classes of rent share and owner managed forms of organization regarding the extent to which a specific form accommodates specialization between labor and management as a result modern explanations of agricultural organizations are misleadingly dependent on risk aversion or the assumption that landowners have an absolute advantage in production decisions viewing the agricultural firm as a constitution instead of as a nexus of contracts facilitates an agency explanation of alternative organizational forms and their amenability to specialization

the nature of the farm abstract using a model based on a trade off between moral hazard incentives and gains from specialization this paper explains why farming has generally not converted from small family based firms into large factory style corporate firms nature is both seasonal and random and the interplay of these qualities generates moral hazard limits the gains from specialization and causes timing problems between stages of production by identifying conditions in which these forces vary we derive testable predictions about the choice of organization and the extent of farm integration to test these predictions we study the historical development of several agricultural industries and analyze data from a sample of over 1 000 farms in british columbia and louisiana in general seasonality and randomness so limit the benefits of specialization that family farms are optimal but when farmers are successful in mitigating the effects of seasonality and random shocks to output farm organizations gravitate toward fa

the division of labor coordination costs and knowledge this paper considers specialization and the division of labor a more extensive division of labor raises productivity because returns to the time spent on tasks are usually greater to workers who concentrate on a narrower range of skills the traditional discussion of the division of labor emphasizes the limitations to specialization imposed by the extent of the market we claim that the degree of specialization is more often determined by other considerations especially emphasized are various costs of coordinating specialized workers who perform complementary tasks and the amount of general knowledge available

family economics and macro behavior in this 1987 presidential address to the american economic association the author explores the contributions of the field of family economics to macroeconomic analysis the focus is on family behavior as an active endogenous factor that both affects and is affected by the evolution of the economy much of the time is spent on long term economic growth although i also discuss short and long cycles in economic activity and the interaction between overlapping generations through social security transmission of inequality and in other ways many conclusions in these and presumably other macro areas change radically when family choices get the attention they deserve excerpt

the fable of the bees an economic investigation ever since a c pigou wrote his books on welfare a divergence between private and social costs has provided the main argument for instituting government action to correct allegedly inefficient market activities the analysis in such cases has been designed less to aid our understanding of how the economic system operates than to find flaws in it to justify policy recommendations both to illustrate the argument and to demonstrate the nature of the actual situation the quest has been for real world examples of such defects

the structure of a contract and the theory of a non exclusive resource the process of arriving at a useful concept of analysis is not only slow and painful but also may go astray and attain nothing useful someone begins with one example or observation followed by a theory which is intuitively plausible a theoretical term associated with a vague concept is coined examples of a seemingly different type emerge which call for another theory the process goes on as examples and theories continue to accumulate the different categories under the same heading of analysis serve only to confuse and each associated theory becomes ad hoc such has been the fate of the concept of externality a more useful approach i think is via contractual conditions the example chosen for illustration is marine fisheries where the fishing right is taken

the structure of contracts and transaction costs note it is the purpose of this note to consider the determinants of contract provisions in particular those that stipulate possible actions in the event of the breach of the terms in a credit contract this category of provisions is generally called creditors remedies when used in credit contracts the use of creditors remedies collateral in particular to reduce the likelihood of loan default has been examined in earlier papers 1 2 robert barro s paper 1 p 455 in concluding suggested that useful extensions to the model would include generalizations to the form of the loan contract introduction to other types of transactions costs and analysis of the loan period although we do not extend barro s model we do extend some of his concepts in the direction suggested in particular we will show that a theory based on nonzero information costs is capable of explaining the observed variation in the form or structure of credit contracts and their use of explicit remedies

the origins and dynamics of taiwan s r d consortia a series of collaborative r d ventures have emerged in taiwan within a quite distinctive institutional framework unlike the case of many of the collaborative arrangements between established firms in the us europe or japan where mutual risk reduction is frequently the driving influence in the case of taiwan it is technological learning upgrading and catch up industry creation that is the object of the collaborative exercises the taiwan r d alliances were formed hesitantly in the 1980s but have flourished in the 1990s as institutional forms have been found which encourage firms to cooperate in raising their technological levels several alliances could be counted in taiwan in the late 1990s bringing together firms and public sector research institutes with the added organizational input of trade associations and catalytic financial assistance from government the article discusses the evolving organizational architecture of these r d alliances utilizing several case studies and seeks to draw comparisons between these institutional innovations in taiwan and established collaborative arrangements in the usa japan and europe

transactions costs and the efficient organization of production a study of timber harvesting contracts a transaction costs framework is developed to explain the choice between lump sum and per unit payment provisions in private timber harvesting contracts predictions about which contract type minimizes the transaction costs of presale measurement and contract enforcement and monitoring are derived and tested using private timber sales contracts from north carolina the empirical results provide strong support for the transaction costs approach and also reject several predictions from a risk based model the transaction costs framework also provides insights into the choice between negotiated and competitive sales procedures

a regulatory assessment of the electricity merchant transmission investment in eu current eu energy policy calls for a well integrated internal energy market by 2020 aimed at achieving interconnection of at least 10 of the installed electricity production capacity for all member states ms in 2030 this target will increase to 15 expanding to include the construction of electricity highways to connect ms and non eu neighbouring countries in order to fulfil energy and climate goals while most cross borders interconnections are envisaged as regulated lines private players will play a significant role in increasing interconnection via the merchant transmission investment mti exception by reviewing the procedural and substantive treatment of the existing five mti interconnectors this paper evaluates whether the existing legal and regulatory framework adopted in the eu represents a suitable model for the development of cross border interconnections further the paper explores the mti exception as a potential model for cross border interconnection with non eu neighbouring countries this analysis demonstrates that mti s potential contribution would not significantly impact the achievement of the 2020 target moreover the existing regulatory framework for merchant lines among ms is not apt for mti developed between ms and non eu countries since the interconnection developed with non eu neighbouring countries to date has necessitated non market characteristics too extraordinary to be practical on a continuing basis

the inverse relationship between productivity and farm size a test using regional data from india the farm size productivity debate for india needs little introduction it has occupied a prominent position in the agricultural economics literature since 1962 when sen observed that indian farm management data revealed an inverse relationship between farm size and yields per acre since then no fewer than twenty journal papers have appeared on this subject sen 1975 the objective of this paper is to test two hypotheses that were either not given enough attention or left unresolved in the debate the first is that the inverse relationship is valid for all of indian agriculture it is not merely a phenomenon observed in a few sample villages this means a test of the hypothesis that the small farm sector as a whole is more productive than the large farm sector in indian agriculture the second hypothesis is that the inverse relationship is true only of a traditional agriculture and that it breaks down with technical progress a methodology is developed below which uses cross sectional regional data to test the two hypotheses simultaneously on applying this methodology to indian district level data 272 districts for 1970 71 it is found that the hypothesis of the small farm sector being more productive than the large farm sector cannot be rejected at low levels of agricultural technology but can be rejected at higher levels this suggests that the inverse relationship between yields and farm size although valid for a traditional agriculture cannot be assumed to exist in an agriculture experiencing technical change

fostering sustainability through sourcing from small businesses public sector perspectives this article examines the opportunities for fostering sustainable development through public sector sourcing from small and medium sized enterprises smes buying from small businesses can make such contributions in a variety of forms ranging from a contribution to local economic development through providing innovative green products and services particularly in the food sector to helping the public sector organisation to better align its operations with its community sourcing from small businesses also has implications for the governance of sourcing processes and can benefit from a partnership approach barriers to public sector sourcing from small businesses are discussed and suggestions made on how these can be overcome

altruism in the family and selfishness in the market place adam smith argued in a famous passage that people are selfish in their market transactions it is not from the benevolence of the butcher the brewer or the baker that we expect our dinner but from their regard to their own interest we address ourselves not to their humanity but to their self love and never talk to them of our own necessities but of their advantages 1937 p 14 in an earlier study he said with irony we are not ready to suspect any person of being defective in selfishness 1853 p 446 selfishness in market transactions has been assumed in practically all subsequent discussions of the economic system objections were dismissed with vague allusions to human nature or with an assertion that altruism loses out to selfishness in the struggle to survive in the market sector yet altruism is generally recognized to be important within a family again adam smith said

the relation between farm size and farm productivity the role of family labor supervision and credit constraints abstract the paper shows that if the performance of hired farmhands is affected by supervision from family members and if the availability of credit is dependent on the amount of land owned then a systematic positive or negative relationship between per acre yields and farm size will prevail a model with no supervision effects on labor productivity would predict that yields are unaffected by farm size the paper also investigates the relation between land utilization and owned holding size when land rental possibilities are limited results are shown to be compatible with various observed patterns in ldcs
