one size fits all towards a differentiated regional innovation policy approach innovation has moved to the foreground in regional policy in the last decade concrete policies were shaped by best practice models derived from high tech areas and well performing regions these are often applied in a similar way across many types of regions here an attempt is made to show that there is no ideal model for innovation policy as innovation activities differ strongly between central peripheral and old industrial areas in this paper we analyse different types of regions with respect to their preconditions for innovation networking and innovation barriers based on this classification different policy options and strategies are developed

evaluating welfare reform in the united states this paper reviews the economic literature on welfare reform over the 1990s a brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes the paper then critically reviews the econometric and experimental literature on caseload changes labor force changes poverty and income changes and family formation changes a growing body of evidence suggests that recent policy changes have influenced economic behavior and well being one particular set of new style welfare programs seems to show especially promising results with significantly increased work and earnings and reduced poverty

universities as strategic actors in the knowledge economy the university plays a particular role in the global knowledge economy as provider of both public and private goods related to education research and societal impacts at the same time universities in the plural play many different roles and exhibit a rich experimentation in organizational forms and knowledge foci adapting to local and global conditions there is also an aspect of uneven regional development and agglomeration of competencies as the individuals and organizations must also balance local interests and stakeholders with global networks in science technology and innovation thus we can identify empirically that universities are changing their strategies organizational structures and competencies in order to respond to new external demands and internal management practices bonaccorsi and daraio 2007 the question is how to explain this theoretically and identify empirical trends and pathways little previous research has focused upon how universities are learning to compete and why they try to act strategically this article as well as the selected articles in the special issue focus upon how and why this transition is occurring as well as the impacts for understanding universities as strategic actors in the knowledge economy section 2 provides an overview it introduces the three themes and articles collected in this special issue providing a summary of the main contributions section 3 then provides our perspective on how to analyze and understand universities as strategic actors it discusses relevant literature as a way of beginning to provide our perspective of the necessity and elements involved in a more united theoretical and empirical understanding this includes statement of predictions as well as empirical evidence that these trends are occurring section 4 concludes with relevant research themes for the future

scale economies and consolidation in hog slaughter we use establishment based panel data to estimate a cost function which identifies the role of scale economies in hog slaughter consolidation we find modest but extensive technological scale economies in the 1990s and they became more important over time but wages rose sharply with plant size through the 1970s and those wage premiums generated a pecuniary scale diseconomy that largely offset the effects of technological scale economies the size wage relation disappeared in the 1980s with growing technological scale economies and disappearing pecuniary diseconomies large plants realized growing cost advantages over smaller plants and production shifted to larger plants copyright 2000 oxford university press

accounting for the decline in afdc caseloads welfare reform or the economy we use state level monthly panel data to assess the relative contributions of the macroeconomy and welfare reform in accounting for the 1993 96 decline in aid to families with dependent children afdc caseloads our results suggest that the decline in per capita afdc caseloads is attributable largely to the economic conditions in states and not to waivers from federal welfare policies nationwide we attribute 66 percent of the decline to the macroeconomy however we do find substantial heterogeneity in the impact and timing of alternative waivers on afdc caseloads states with waivers impacting parental responsibilities experienced greater caseload declines than states with waivers that made work more attractive overall our model predicts that had it not been for the influence of economic factors welfare reform would not have led to any decrease in aggregate caseloads

the tradeoff between oligopsony power and cost efficiency in horizontal consolidation an example from beef packing in this paper we model the tradeoff between regional oligopsony power and cost efficiency resulting from consolidation in a food processing industry the model can be used to calculate the cost reductions necessary to offset the anticompetitive effects of market power and to compare them to actual cost savings achieved through plant scale or multiplant operating economies for an application we choose the beef packing industry for this case we find that the estimated cost savings necessary to neutralize the anticompetitive effects of consolidation in beef packing are about half the actual cost savings from scale economies

the effects of the macroeconomy and welfare reform on food stamp caseloads since 1994 there has been an unprecedented decline in the number of people receiving food stamp benefits from a record high of 27 5 million in 1994 the number of food stamp recipients fell over 30 to 18 0 million by mid 1999 during this period the united states has experienced the third longest economic expansion of the twentieth century this has resulted in a dramatic growth of new jobs and the lowest unemployment rate in a generation simultaneously the welfare system has undergone a major transformation beginning in the early 1990s when many states made changes to their welfare programs through federal waivers from aid to families with dependent children afdc requirements the personal responsibility and work opportunity reconciliation act of 1996 prwora furthered these changes by replacing afdc where states contributions were matched by the federal government with a block grant program called temporary assistance for needy families tanf prwora introduced new rules on tanf recipients such as terminal time limits work requirements and personal responsibility measures it also directly changed the food stamp program by ending the eligibility of some recipients and reducing average benefit levels at the same time innovative changes in the delivery of food stamp benefits have been taking place with the introduction of electronic benefit trans

contract production of peas abstract this article analyzes a contract between farmers and the processor danisco foods production of peas for consumption requires highly accurate coordination obtained through centralized decision making the contract is based on a tournament system providing risk sharing between the farmers general problems known from contract theory such as hold up moral hazard risk sharing and discrimination are analyzed the article illustrates trade offs between these problems in the design of contracts by negotiating the contract through the pea growers association the farmers gain some bargaining power thereby the farmers ensure that danisco foods uses only one contract for all farmers this article analyzes the consequences of the farmers strategy throughout the analysis several modifications of the contract are suggested in order to improve the incentives

from knowledge based economy to knowledge based economy reflections on changes in the economy and development policies in the north east of england hudson r from knowledge based economy to knowledge based economy reflections on changes in the economy and development policies in the north east of england regional studies against the background of claims made about the emergence of a new knowledge based economy the paper explores the role of knowledge learning and innovation in the economy and in relation to regional economic development and to successive conceptions of regional development policies through the lens of the successive transformations of a particular regional economy that of north east england rather than seeing knowledge as something that has only recently become relevant to economic performance and to understanding of the economy and economic development it is argued that knowledge is central to all economic activity and that different types of such activity draw upon and require different types of knowledge

testing the theory of tournaments an empirical analysis of broiler production broiler chickens are raised by contract growers whose rewards depend explicitly upon relative performance we use data on the performance of broiler producers facing both tournament and linear performance evaluation compensation structures to test three predictions from the theory of tournaments that changes in the level of prizes that leave prize differentials unchanged will not affect performance that in mixed tournaments more able players will choose less risky strategies and that tournament organizers will attempt to handicap players of unequal ability or reduce mixing to avoid the disincentive effects of mixed tournaments our evidence is consistent with each prediction

universities technology and innovation centres and regional development the case of the north east of england the paper examines the role of technology and innovation centres tics in bridging the gap between the university research base and industry in order to foster economic development in a lagging industrial region the context is provided by an academic literature on the role of universities in regional innovation systems some of which casts doubt on the capacity of universities to operate in this domain particularly within a lagging region the empirical case reports on a bold experiment initiated by the regional development agency in the older industrial region of the north east of england to create and support new tics in the fields of process innovation in high value manufacturing and new and renewable energy and on the engagement of a regionally committed university with these centres the evidence presented suggests that while there are links between the university and the centres both are principally operating in a national science and technology system in which contributing to addressing uneven regional economic development is a secondary concern copyright the author 2012 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

does the welfare state destroy the family evidence from oecd member countries we study the effect of the size of the welfare state on family outcomes in oecd member countries exploiting exogenous variation in public social spending due to varying degrees of political fractionalization i e the number of relevant parties involved in the legislative process we show that an expansion in the welfare state increases the fertility marriage and divorce rates with a quantitatively stronger effect on the marriage rate we conclude that the welfare state supports family formation nevertheless we also find that the welfare state decouples marriage and fertility and therefore alters the organization of the family authors abstract

lucky in life unlucky in love the effect of random income shocks on marriage and divorce abstract economists have long been interested in the extent to which economic resources affect decisions to marry and divorce however this issue has been difficult to address empirically due to a lack of exogenous income shocks we overcome this problem by exploiting the randomness of the florida lottery and comparing recipients of large prizes to those of small prizes results indicate that while positive income shocks of 25 000 to 50 000 do not cause statistically significant or economically meaningful changes in divorce rates single women are less likely to marry as a result of the additional income

human capital graduate migration and innovation in british regions with the aid of a geographical information system our paper constructs a three stage least squares simultaneous equation model to investigate the interrelationships between the interregional flows of human capital and the innovation dynamism of a region in order to do this we model the interregional migration behaviour of high quality british university graduates from university into first employment and we relate these human capital flows to both the labour market characteristics and the knowledge characteristics of the employment regions this is done for all industries and separately for just high technology industries our results indicate that for england and wales there is a two way causality between the interregional human capital employment migration flows of recent university graduates and the innovation performance of regions however the results for great britain as a whole depend on whether london is included and scotland is excluded we find little or no support for the argument that the presence of local universities or small firms promotes regional innovation

targeting transfers through restrictions on recipients our objective is to design transfer programs that maximize some social welfare function following the optimal income tax formulation we assume that a random process endows individuals with characteristics that influence welfare such as ability to earn income medical condition or unmonitorable income the goal is to maximize the utility of a randomly chosen individual other individualistic social welfare functions would lead to equivalent results if the random characteristics were observable a first best outcome could be achieved by making them the basis for lump sum transfers in practice however we can observe only indicators of these characteristics such as earnings medical expenditures or consumption patterns the challenge for policy is to design an efficient second best transfer program based on indicators in this paper we argue that 1 an optimal transfer program in general must sacrifice productive efficiency to target efficiency this is done by imposing restrictions on the choices made by intended beneficiaries 2 a program that incorporates restrictions such as means tested in kind transfers commodity specific taxes and subsidies and even ordeals i e the imposition of deadweight costs to qualify for a transfer will perform better than programs that rely solely on income taxes and cash transfers

policy watch the 1996 welfare reform welfare reform legislation was passed in the summer of 1996 four key research questions that the new law presents to social scientists are as follows 1 can states design and operate better programs than afdc this includes questions about the ability of afdc women to work a significant number of hours the legislation s effect in areas of concentrated urban poverty and the extent to which women will be able to improve their families economic status under the legislation 2 will jobs be available 3 how will the new block grant affect states fiscal situation and 4 what new research methodology questions does this legislation introduce

technology systems and technology policy in an evolutionary framework the central purpose of this paper is to outline an evolutionary theory of technology policy and to connect it with the emerging literature on national systems of innovation any understanding of technology policy must be based on a clear understanding of the nature of technology and the important differences between science and technology technology can be treated in terms of knowledge skills and artifacts and in each case there are different variety generating mechanisms different selection processes and different institutional structures for policy purposes the degree of connection between these different dimensions of technology is at the core of technology policy c 1995 academic press inc copyright 1995 by oxford university press

mid range universities linkages with industry knowledge types and the role of intermediaries we analyze how mid range universities can contribute to industrial change through the transfer of tacit and codified knowledge in the areas of spin offs licensing and patents contract research consultancy and reach out and graduate and researcher mobility we use archival survey and interview data relating to mid range universities in mid range environments in the uk belgium germany and sweden our findings suggest that mid range universities primarily need to focus on generating world class research and critical mass in areas of expertise as well as developing different types of intermediaries mid range universities may need to develop a portfolio of university industry linkages in terms of the scope of activities and the types of firms with which they interact we also show that different intermediaries have important roles to play in developing university industry linkages for mid range universities

market and cost structure in the u s beef packing industry a plant level analysis a resurgence of consolidation in the u s meat packing industry in the past few decades has stimulated academic and policy debate issues raised include the role of cost economies in driving these patterns and the effects on the agricultural sector cattle producers from market power here plant level cost and revenue data for u s beef packing plants are used to estimate a cost based model incorporating cattle and output market pricing behavior the robust results indicate little market power exploitation in either the cattle input or beef output markets and that any apparent evidence is counteracted by cost efficiencies such as utilization and scope economies copyright 2001 oxford university press

broiler production contracts as a multi agent problem common risk incentives and heterogeneity the broiler industry presents two puzzles regarding production contracts why do processors control growers inputs and why do they use a statistically insufficient estimator to calculate growers compensation this paper provides an agency theoretic framework that explains these puzzles in terms of processors response to grower heterogeneity and production risk and to grower risk aversion processors control inputs to reduce the information rents paid to agents by forcing agents to bear additional income risk through the use of an imprecise estimator processors can increase profits due to the combined moral hazard adverse selection nature of the informational problem

the national system of innovation in historical perspective contrary to some recent work on so called globalisation this paper argues that national and regional systems of innovation remain an essential domain of economic analysis their importance derives from the networks of relationships which are necessary for any firm to innovate whilst external international connections are certainly of growing importance the influence of the national education system industrial relations technical and scientific institutions government policies cul tural traditions and many other national institutions is fundamental the historical examples of germany japan and the former ussr illustrate this point as well as the more recent contrast between east asian and latin american countries introduction the national system of friedrich list according to this author s recollections the first person to use the expression national system of innovation was bengt ake lundvall and he is also the editor of a highly original and thought provoking book 1992 on this subject however as he and his colleagues would be the first to agree and as lundvall himself points out the idea actually goes back at least to friedrich list s conception of the national system of political economy 1841 which might just as well have been called the national system of innovation the main concern of list was with the problem of germany overtaking england and for underdeveloped countries as germany then was in relation to england he advocated not only protection of infant industries but a broad range of policies designed to accelerate or to make possible industrialisation and economic growth most of these policies were concerned with learning about new technology and applying it the racialist and colonialist overtones of the book were in strong contrast to the inter nationalist cosmopolitan approach of the classical free trade economists and list s belief that holland and denmark should join the german bund and acquire german nationality because of their descent and whole character reads somewhat strangely in the european community of today nevertheless despite these unattractive features of his outlook he clearly anticipated many contemporary theories after reviewing the changing ideas of economists about development in the years since the second world war the world bank 1991 concludes that it is intangible investment in knowledge accumulation which is decisive rather than physical capital investment as was at one time believed pages 33 35 the report cites the new growth theory

marriage and economic incentives evidence from a welfare experiment can economic incentives be used to affect marriage behavior and slow the growth of single parent families this paper provides new evidence on the effects of welfare benefit levels on the marital decisions of poor women exogenous variation in welfare benefit incentives arises from a randomized experiment carried out in california that allows me to measure responses beyond simple year to year changes in benefit levels i find that a regime of lower benefits and stronger work incentives encourages married aid recipients to stay married but has little effect on the probability that single parent aid recipients marry the effects on married recipients become larger over time suggesting that long run effects may exist

market size fixed costs and horizontal concentration abstract a cournot oligopoly model is used to relate horizontal concentration to market size and fixed costs assuming that higher fixed costs yield a lower level of marginal costs a vertically and horizontally growing market size is shown to cause horizontal concentration to decline if there is free entry in an empirical test focusing on changes in total production the number of suppliers and the variance of market shares in 291 lines of business in west germany over the period 1978 1993 we find evidence for the existence of entry barriers

implications of nash bargaining for horizontal industry integration this article shows how horizontal industry integration can arise from transferable asymmetry of technologies and endowments the nash bargaining solution suggests that greater technological diversity among coordinating parties yields greater gains from horizontal integration the framework fits the case where a firm with a superior technology franchises the technology by horizontal integration the results appear to fit hog production where integration has been primarily horizontal and in part broiler production where integration has been both vertical and horizontal specifically technology has been shared through uniform genetic traits fine tuned feed rations and veterinary services specified in grower contracts

leadership and the provision of safe food modern food production typically involves many interacting stages and two or more decision makers there is reason to believe that inputs in determining quality likely complement and it is not possible to regulate many of these inputs in a food production system possessing these characteristics we show that leadership by one or more firms through communicating actions may be used as a mechanism to increase overall food quality as there may be no private incentive to lead there may be strategic merit in assigning liability through legislation we also suggest the possibility that genetics are leadership instruments in hog production systems copyright 2001 oxford university press

the league composition effect in tournaments with heterogeneous players an empirical analysis of broiler contracts we compare welfare effects of tournaments and piece rates in contracts with heterogeneous ability agents and demonstrate that tournaments that mix players of unequal abilities create a league composition effect when leagues are fixed and the time horizon sufficiently long piece rates improve welfare over tournaments using contract production data for broiler chickens we estimate the variances of growers abilities common production shock and grower s idiosyncratic shock growers abilities are heterogeneous and common production shocks are significant leagues in broiler tournaments disintegrate rapidly over time suggesting that tournament contracts offer more welfare than piece rates

incentives information systems and competition we show how dierent competitive regimes aect the ability to provide incentives based on noisy information systems reduced com petition facilitates incentive provision this may rationalize both ver tical integration and horizontal integration as seen in many agricul tural markets with uncertain quality grading moreover if trading terms are settled before the information is observed a noisy infor mation system su ces to give proper incentives this may rationalize the use of long term conditional price contracts in the trading of many agricultural products

information asymmetry as a reason for food industry vertical integration three trends that have been subject to recent discussion are a movement away from undifferentiated agricultural commodities toward more specialized products reduced reliance on open markets for raw agricultural products and a movement toward agricultural industrialization recent research suggests that demographic trends may be causing the first trend while the other two are closely related phenomena this research suggests that information externalities arising from uncertainty concerning the nature of food quality and problems in detecting quality may be reasons why vertical coordination is being used to circumvent the marketplace

the impact of welfare on young mothers subsequent childbearing decisions the impact of welfare on fertility in the united states is explored focusing on the theory that some women have many children to increase their incomes and to prolong their stay on welfare rolls the author examines the relationship between welfare and births to women who already have a child using data on young mothers from the national longitudinal survey of youth nlsy i find that variations in welfare benefit levels and the incremental benefit have no statistically significant impacts on the subsequent childbearing decisions of young mothers in general nor on the subsequent childbearing decisions of women who received welfare in particular furthermore mothers who received welfare to support their first children are no more likely to have additional children in any given year through the age of 23 excerpt

input control in agricultural production contracts tion problems there will be distortionary effects on industry output and returns from production will be distributed in a predictable way regardless of the underlying motivation for contract design the resulting distribution of returns and risks is likely to differ from the traditional spot market distribution understanding the incentives underlying the design of agricultural production contracts will aid in predicting their influence on the distribution of returns as their usage increases in addition to its practical importance the economic analysis of agricultural production contracts provides an opportunity to test contract theory empirically over the past twenty years contract theory or mechanism design has burgeoned as an area of theoretical analysis this growth in the theory has not been matched by an accompanying empirical literature there has been only a limited amount of empirical work in these areas primarily on auctions as well as executive compensation and franchising cf laffont ossard and vuong jensen and murphy and lafontaine agricultural production contracts provide an opportunity to test whether asymmetric information models have explanatory value i consider whether such models are sometimes observationally equivalent to other economic models and what research techniques will aid in distinguishing among explanations i address these issues in the context of a

agricultural markets as relative performance evaluation relative performance schemes such as tournaments are commonly used in markets for a variety of livestock and processing commodities while explicit versions of these schemes are rarely used in markets for fresh fruits and vegetables and specialty grains we show how contracts for these latter commodities do in fact provide relative performance incentives albeit indirectly via a payment mechanism that depends on market prices in such contracts compensation is often an increasing function of revenue this implements a relative performance scheme by making each grower s payment an increasing function of his own output but a decreasing function of other s output in an important 1982 article holmstr om models the problem facing a group of agents each of whom produces an observable quantity of some good by taking an unobservable action a rather robust conclusion from this line of inquiry is that when the production of one agent is not independent of the production of another then the compensation awarded to the first agent should depend not only on his own production but also on the output of others in particular if agents production is positively correlated because of some common shock for example then an agent s compensation should be larger when other agents output is smaller a phenomenon which holmstr om terms relative performance evaluation relative performance evaluation ought to be particularly important for agricultural producers and the various intermediaries who purchase their output these producers face considerable common risk from aggregate production shocks and so one would expect that relative performance evaluation could improve efficiency in fact certain types of agricultural intermediaries do use explicit relative performance schemes as predicted by
